A large literature has established that the International Monetary Fund (IMF) is heavily politicized.Footnote 1 Despite considerable shifts in the global balance of economic power, influence over the IMF has been largely path dependent.Footnote 2 Several creditor states, particularly the United States and major European countries, continue to exercise outsized influence over IMF lending.Footnote 3 This influence exercised by a subset of states in the IMF—through their overrepresented voting shares, personnel, or informal influence—distorts the application of conditional lending, resulting in harsh treatment of some states and lenient policies toward others. In turn, political intervention often reduces the credibility of IMF conditionality and undermines reforms in borrowing states.Footnote 4
We argue that political imbalances in IMF governance have broader consequences for the global economy. Political influence vis-à-vis the IMF affects expectations about whether and how the institution will intervene in the event of a crisis. This alters the incentives of policymakers and private investors, encouraging risk taking in some countries but not others. Countries that expect favorable treatment from the IMF are subject to moral hazard: the expectation of a generous bailout reduces the perceived costs of risky policies, such as holding less international reserves or relaxing financial regulations. By contrast, countries lacking political influence in the IMF face strong incentives to pursue self-insurance. In effect, the IMF is a biased global insurance mechanism: moral hazard associated with IMF lending is distributed asymmetrically across the international system. “Too big to fail” is a function not of economic importance per se, but of political clout vis-à-vis the IMF.
Our article makes several novel empirical contributions. First, using a panel data set covering the period from 1980 to 2010, we show evidence consistent with the asymmetrical distribution of IMF moral hazard. Specifically, greater political influence vis-à-vis the IMF is associated with: (1) more generous treatment by the IMF (higher likelihood of receiving IMF lending with fewer conditions); (2) underinsurance (lower level of international reserves); and (3) more frequent financial crises (higher likelihood of currency and banking crises). The first finding reinforces the existing literature on IMF lending, while the last two are novel and suggest that political distortions associated with IMF governance have important, previously underexplored effects on international economic relations. We also develop a new measure of political influence vis-à-vis the IMF using principal component analysis, combining information from proxies used in the existing literature that often produced weak or inconsistent findings.
Second, to evaluate our proposed causal mechanisms, we exploit the expulsion of Taiwan from the IMF. Although the IMF has been often criticized for generating moral hazard, it has been tricky to demonstrate empirically.Footnote 5 The institution has near-universal membership and has existed continuously since World War II as the contemporary international financial system developed and matured. Entry into the IMF generally reflects self-selection. There is therefore no obvious control condition against which to evaluate the effect of IMF moral hazard. However, Taiwan offers a useful counterfactual case. Taiwan was expelled from the IMF in 1980 because of a sovereignty dispute with China, abruptly eliminating the possibility of any financial support. Expulsion was involuntary, the precise timing was unknown ex ante, and the final disposition of Taiwan was uncertain. Using the synthetic control method, we demonstrate that expulsion was associated with a dramatic increase in Taiwan's international reserves, consistent with our predictions. Taiwan has also maintained exceptionally conservative financial policies, citing its inability to rely on the IMF.
Political imbalances in the Bretton Woods Institutions are a major subject of contestation among leading economies, particularly with the rise of China and its initiatives to reshape the international order.Footnote 6 Our empirical results suggest that contestation over the IMF is not a simple matter of national prestige, but an issue with significant consequences for international economic relations. The massive accumulation of reserves among some developing states represents a perverse flow of capital from poor to rich countries, which may contribute to broader economic distortions such as trade imbalances and asset price bubbles.Footnote 7 Most existing explanations of economic imbalances associated with reserve accumulation focus on underlying economic factors or mercantilist motivations.Footnote 8 Our findings suggest that political imbalances in the IMF contribute to economic imbalances by distorting the pattern of international reserve accumulation. Similarly, IMF politicization may account for some of the variation in the cross-national incidence of financial crises, which are disruptive economic events whose causes remain a subject of intense debate.Footnote 9
The IMF As a Biased Global Insurance Mechanism
It is now well known that policymaking in the IMF is heavily biased by the political and economic interests of a subset of member states, particularly the United States and several major Western European countries. Consequently, we may think of the IMF as a biased global insurance mechanism. We argue that this bias produces predictable and consequential distortions in international reserve accumulation and the incidence of financial crises.
In most domestic markets, insurance providers are prevented from overt discrimination based on arbitrary characteristics such as social status and race.Footnote 10 Where discrimination occurs, it tends to be ex ante—at the initial stages of entering into a contract—during which the insurer evaluates the feasibility of insurance and the appropriate premium based on allowable risk factors.Footnote 11 It is therefore unusual for insurers to discriminate against policyholders ex post—upon filing of an insurance claim—unless there is reason to suspect material misrepresentation of facts. Similarly, a domestic lender of last resort, such as a central bank, has the regulatory capability to perform ex ante screening—banks that fail to meet risk criteria, such as capital adequacy rules, can be reprimanded or shut down.Footnote 12 This capability is much more limited at the international level where, under normal conditions, a lender of last resort such as the IMF has limited ex ante control over the economic policies of sovereign governments. Available tools tend to be limited to surveillance and consultation.Footnote 13
These limitations put a much greater onus on ex post discrimination for the IMF. When a country experiences balance-of-payments difficulties, the IMF must weigh easy provision of rapid liquidity, which facilitates a resolution to the country's problems, and moral hazard concerns, the possibility that a bailout will incentivize risky behavior in the future. Hence, a decision by the IMF to lend, and on what terms, is a tricky one involving considerable discretion on a case-by-case basis. Consequently, IMF lending decisions tend to be heavily politicized.
Work by both political scientists and economists has shed light on the biases of IMF decision making.Footnote 14 The IMF is relatively path dependent: the institution tends to underrepresent the interests of countries that experienced rapid economic growth since the end of World War II, limiting the ability of Japan and most developing countries to directly shape IMF policy outcomes.Footnote 15 Hence, Western nations, particularly the United States and major European countries, continue to exercise outsized influence over IMF lending decisions.Footnote 16
Our assertion is that political distortions of IMF decision making have broader, systemic consequences for the global economy. The politicization of the IMF follows a predictable pattern. The IMF tends to discriminate against a certain set of country characteristics that have no relevance to economic merits, much as a domestic insurer might discriminate based on economically irrelevant characteristics such as gender, race, or sexual orientation. This pattern of discrimination has important consequences for member states’ policy decisions as well as the general operation of the global financial system.
We focus on two potential sources of discrimination. First, IMF lending can be biased by political imbalances within the decision-making structures and practices of the institution. The United States and major European countries exert outsized influence over IMF decision making, thanks to both formal features such as overweighed voting shares and informal factors, such as overrepresentation of nationals among staff and privileged access to information.Footnote 17 Hence, IMF lending tends to be more forthcoming and generous for countries that are either directly overrepresented or have close economic or diplomatic ties to influential states. Second, as we discuss more extensively in the empirical section, in one extreme case, any possibility of IMF support was terminated for a major economy—Taiwan—for nontechnocratic, political reasons.
Scholars have often called attention to the potential for the IMF to produce moral hazard in the international system.Footnote 18 Our argument is that this potential for moral hazard is asymmetrically distributed. Moral hazard is particularly acute for countries that anticipate generous treatment from the IMF because of direct overrepresentation or strong political or economic ties to influential states within the institution. Equally problematic, but less frequently discussed, is the distortion produced by lack of influence vis-à-vis the IMF. The perception that the IMF is not responsive to their concerns can curtail financial institutions’ incentives to engage in cross-border lending and lead countries toward aggressive accumulation of foreign reserves as a means of self-insurance.
Our predictions are summarized in Table 1. If our premise is correct, countries that are subject to asymmetrical moral hazard—because of direct influence over the IMF or indirect influence through their close ties with the US or major European states—should receive more frequent lending from the institution with less onerous conditionality: this has been well documented in existing literature.Footnote 19 Our core predictions concern the broader consequences of asymmetrical moral hazard on reserves and financial crises: (1) countries that are politically influential vis-à-vis the IMF will hold a lower level of precautionary international reserves because the IMF offers a readily available and attractive insurance mechanism. On the other hand, countries with limited political influence vis-à-vis the IMF will purse self-insurance by holding a higher level of reserves. (2) Political influence vis-à-vis the IMF will be associated with more frequent financial crises. This follows from the asymmetrical moral hazard generated by expectations of generous treatment by the IMF. Expectations of IMF favoritism create incentives for policymakers to pursue risky policies—for example, holding low levels of reserves, loosening financial regulations, or promoting short-term capital inflows—and for private actors to pursue risky lending and investments on the assumption that a generous bailout will be forthcoming in the event of a crisis. In turn, these incentives will elevate the risk of financial crises among countries that are politically influential vis-à-vis the IMF.
Mexico perhaps offers the clearest example of a country subject to asymmetrical moral hazard. Because of its geographical location in North America, Mexico has deep economic ties with the United States in trade, investment, and financial flows.Footnote 20 US policymakers often worry that a disorderly Mexican crisis would trigger large cross-border migrant flows.Footnote 21 The formal and informal influence of the US in the IMF means that Mexico can typically expect generous treatment by the institution. For example, Mexico received rapid support during the 1994 Mexican crisis, when the IMF assembled a $30 billion emergency loan package on top of the $20 billion support promised by the US.Footnote 22 Despite high levels of exposure, US financial institutions emerged relatively unscathed: for example, there were no credit agency downgrades of US financial institutions in 1994 citing the Mexican crisis.Footnote 23
Mexican authorities have also exhibited behavior consistent with asymmetrical moral hazard. Mexican reserves did not increase after IMF intervention in 1994: Mexico chose not to pursue self-insurance despite experiencing a major crisis.Footnote 24 Instead, Mexican authorities have turned repeatedly to the IMF. Between 1952 and 2009, Mexico initiated a new IMF program about once every six years.Footnote 25 Only five years after the Mexican crisis, Mexican authorities entered into an IMF program in response to instability triggered by the 1998 Asian crisis.Footnote 26 During the 2008 global financial crisis, Mexico became the first country to express interest in the IMF's Flexible Credit Line (FCL), a short-term loan lacking the stringent requirements typical of longer-term IMF loans, and it was granted a $47 billion credit line less than a month after application. The FCL arrangement was renewed repeatedly and remains in place as of 2018.Footnote 27
The experience of East Asian countries since the 1997–1998 Asian financial crisis offers a useful contrast.Footnote 28 During the crisis, many regional policymakers felt that the IMF systematically ignored their views and imposed inappropriate policy measures preferred by the US and European states.Footnote 29 Delays in IMF disbursement prompted nations with ailing economies to question the fund's ability to deal with international economic emergencies swiftly and effectively.Footnote 30 Japanese financial institutions, which were heavily exposed to the crisis economies, suffered serious losses: Moody's downgraded all major Japanese banks in 1997–98 explicitly citing exposure to the Asian crisis.Footnote 31
Underlying East Asian skepticism toward the IMF is the perception that the institution poorly reflects the region's interests. Formal underrepresentation in the IMF has been a major diplomatic concern for East Asian states: voting power in the institution underweights the region compared to the West.Footnote 32 East Asian states are also underrepresented in terms of nationals among IMF staff.Footnote 33 The region's economic ties are heavily tilted toward Japan, and more recently China, which themselves exercise relatively weak informal influence over the institution's policies.Footnote 34 For these reasons, government officials in East Asia have argued that the IMF does not appropriately reflect their preferences and often imposes excessively harsh conditionality compared to other potential borrowers.Footnote 35
Their perceived lack of influence in the IMF has compelled many East Asian countries to pursue self-insurance through precautionary reserve accumulation.Footnote 36 A Japanese Ministry of Finance official noted that, after the Asian crisis, “each country wants to have its own insurance policy and not rely on the IMF.”Footnote 37 John Lipsky, first deputy managing director of the IMF, agreed that “Global economic efficiency would have been enhanced if the IMF had been able to provide the insurance demanded by [Asian] countries, but doubts about the amount of available financing and the conditions attached to this financing have encouraged self-insurance.”Footnote 38
In contrast to Mexico, Asian countries have shied away from the IMF after the 1997–98 crisis. During the 2008 global financial crisis, of thirty emerging economies that received IMF financing, none were from East Asia. Several regional countries that came under pressure publicly ruled out IMF support and instead sought bilateral swaps from the US Federal Reserve.Footnote 39 Thai Finance Minister Korn Chatikavanij publicly noted that the IMF remains heavily stigmatized in the region.Footnote 40
Expanding on this illustrative discussion, the next section provides a general test of our propositions. We demonstrate that our theoretical propositions are supported in a panel data set covering 130 countries from 1980 to 2010. Our findings show that countries that can expect to receive favorable treatment from the IMF typically hold lower levels of reserves and experience financial crises more frequently. We then move to consider causal mechanisms, focusing on the expulsion of Taiwan from the IMF in 1980.
Panel Analysis
To test our predictions, we need to proxy for a country's expected influence vis-à-vis the IMF. Existing quantitative analyses of the determinants of IMF lending have used several different measures to quantify political influence. These have typically focused on the possibility that IMF lending might be biased indirectly by a borrower's ties to the US or major European countries. For example, IMF lending appears to be influenced by a country's diplomatic and economic ties to the US or major European countries as expressed by proximity of voting profile in the UN General Assembly,Footnote 41 intensity of trade,Footnote 42 and bank exposure.Footnote 43 Other studies suggest that borrowers may exert influence over the IMF more directly if their nationals make up a large share of IMF employees or they hold a large share of voting power.Footnote 44
Existing work has generally analyzed these proxies in varying combinations, which has often produced inconsistent or contradictory results.Footnote 45 One potential problem is that these variables are intended to proxy for the same underlying concept—the expected political bias of the IMF in favor of a borrower country—and are also relatively highly correlated with each other.Footnote 46 One way to address this issue is to derive a composite measure that draws information from several underlying proxy variables. We use Principal Component Analysis (PCA)Footnote 47 to construct a single-dimension independent variable from eight different variables that have been identified in previous work as plausible proxies for influence over the IMF: number of nationals employed as IMF economists, IMF quota share, UN affinity score with the US and European powers, trade volume with the US and Europe, and US and European bank lending.Footnote 48 Data sources and details for all variables used in our empirical analysis are available in the online appendix. We interpret higher values of the resulting single-dimension independent variable—imf influence—as indicative of greater potential influence over the IMF.
We retain one principal component from the PCA analysis for several reasons. Retaining a single factor is supported by visual inspection of a Scree plot.Footnote 49 The first principal component is also positively correlated with all eight of the original variables, making it a plausible proxy for our theoretical notion of IMF influence, while all other principal components are associated with only a subset of variables with no obvious intuitive interpretation. To consider the possibility that the second component captures a different aspect of influence over the IMF, we also reran the empirical models including two components as explanatory variables, and the coefficient for the second component was inconsistent and generally indistinguishable from zero.
Because the political determinants of IMF lending have been evaluated extensively elsewhere, we focus here on validating our PCA measure. To establish that imf influence is a plausible measure of the likelihood of favorable IMF treatment, we replicate and extend the findings from Barro and Lee, who examined a variety of potential determinants of IMF lending.Footnote 50 The panel data set contains information on 130 countries in five-year increments, that is, 1980–1985, 1985–1990, etc., and we extended the original data over time to encompass 1980–2010. We follow Barro and Lee in using five-year increments because some data, such as representation among IMF personnel, are not available on a yearly basis. Throughout the empirical analysis, independent variables are coded at the beginning of each period, while dependent variables are coded as average levels over the five-year period.
The dependent variables are indicators of IMF lending outcomes: the size of IMF loans as a share of the receiving country's GDP averaged over each five-year period, the fraction of months during each five-year period that a country operated under an IMF loan program,Footnote 51 and a dichotomous indicator for approval of any new IMF programs during the five-year period.Footnote 52 Since lending outcomes may be affected by demand-side factors, we also include a variable that proxies for the stringency of IMF conditionality—the combined total number of prior actions required for loan disbursement, performance criteria, and benchmarks/targets.Footnote 53
Following Barro and Lee, we use Tobit specificationsFootnote 54 for the bounded dependent variables to avoid potential bias from censoring.Footnote 55 For the dichotomous approval variable, we use probit.Footnote 56 We use the economic controls for determinants of IMF lending from Barro and Lee in all statistical models, measured at the beginning of each five-year period: per capita GDP, GDP, the lagged GDP growth rate,Footnote 57 international reserves as a proportion of imports, and a dummy variable indicating membership in the OECD. The squares of per capita and absolute GDP are included to account for any nonlinear relationship between those variables and IMF lending. As Barro and Lee note,Footnote 58 other economic variables, such as magnitude of current account deficits and inflation, are not meaningful predictors of IMF lending once lagged GDP growth and international reserves are included.Footnote 59 We also include dummy variables for each five-year period to control for period-specific effects and report country-clustered standard errors.Footnote 60 Absolute, continuous variables are logged to avoid undue influence of outliers.
The results appear in Table 2. The first three columns show that the imf influence variable is associated, as predicted, with larger IMF loans as a share of GDP, higher rates of participation in IMF programs, and a greater likelihood of IMF loan approval. The fourth column shows that, subject to receiving an IMF program, the imf influence variable is negatively associated with the total number of conditions. In other words, greater influence over the IMF is associated with more generous and frequent lending from the IMF and fewer conditions. These results provide support for our premise that the imf influence variable is a reasonable proxy for political clout vis-à-vis the IMF.
Notes: All independent variables are measured at the beginning of the five-year period. Country-clustered standard errors in parentheses. Asterisk denotes a coefficient at least two standard errors removed from 0. Control variables included in the models but not shown in the table: time period dummies. Observations are in five-year increments (e.g., 1980–1985). IMF-loan GDP ratio is the size of IMF loans as a share of the receiving country's GDP averaged over each five-year period. IMF participation rate is the fraction of months during each five-year period that a country operated under an IMF loan program. IMF loan approval is a dichotomous variable coded as 1 if the IMF approved any new program for the country during the five-year period. Total number of IMF conditions (TC) is measured as the sum of prior actions (PA), performance criteria (PC), and benchmarks/targets (BT).
We now turn to our main analysis. For consistency, we use the same data set covering 130 countries from 1980–2010 we described earlier. Our theoretical prediction is that countries in a position to exert greater influence over the IMF will be more susceptible to moral hazard. These countries are less likely to pursue self-insurance through reserve holdings, and because financial institutions and government policymakers will be more willing to pursue risky behavior, the likelihood of financial crises should be higher. In comparison, countries that have limited leverage over the IMF cannot expect generous treatment in the event of a crisis. Such countries should exhibit a relatively stronger tendency to accumulate reserves for self-insurance and a lower likelihood of crises.
Endogeneity should not be a major concern for the independent variables we use to derive the PCA measure. UN voting affinity and share of IMF staff are unlikely to be affected by a country's reserves or crises. For the other variables, any potential endogeneity will bias the results against findings consistent with our predictions: (1) IMF quotas are, in principle, determined by formulas that include reserves as one input. However, insofar as reserves affect quotas, the relationship should be a positive one, creating a bias against findings consistent with our prediction that countries with high quotas hold a lower level of reserves. (2) Similarly, countries that are seen as risky—holding low reserves and frequently experiencing crises—should attract less, not more, economic ties in the forms of trade and bank lending. In addition, we measure the independent variables at the beginning of each five-year period, while the dependent variables are measured as period averages.
The dependent variable is foreign reserves as a share of GDP.Footnote 61 As with IMF lending, we use Tobit specifications since the dependent variable is bounded at zero: OLS specifications produce substantively similar results.Footnote 62 The results are presented in Table 3. In the first column, we include only our key independent variable, imf influence. In the second column, we include the basic macroeconomic controls used earlier: gdp and gdp per capita and their squares, gdp annual growth, and a dummy for OECD membership. In both specifications, imf influence is statistically significant and negatively associated with reserve holdings.
Notes: Controls included in the models but not shown in the table: time period dummies. Asia and Oil Exporter are omitted from the fixed effects model because of limited temporal variation. Observations are in five-year increments (e.g., 1980–1985, 1985–1990), with reserves measured as a five-year average. All independent variables are measured at the beginning of the five-year period. Country-clustered standard errors in parentheses. Asterisk denotes a coefficient at least two standard errors removed from 0.
The third column includes several additional variables that might be plausibly associated with reserve holdings: the CPI inflation rate, exports, imports, a dichotomous indicator for a currency peg, and a measure of currency undervaluation. Several of these variables are potentially endogenous to government decisions over reserves and should be interpreted with caution. It could be problematic to include these variables in our model because a government that wishes to accumulate reserves for precautionary purposes can do so by weakening the exchange rate and running a current account surplus—we would be effectively controlling for variables that are a consequence of our key explanatory variable.Footnote 63 However, since mercantilism is the leading alternative explanation for reserve accumulation,Footnote 64 it is helpful to examine whether the substantive effect we find runs entirely through the exchange rate and trade channels. The results show that imf influence remains negative and statistically significant even after controlling for these variables.
In the last three columns, we add additional control variables to make sure our results are not biased by unique group- or country-specific factors. To make sure our results are not completely contingent on the East Asian dynamics described in the previous section, we reran the model including a dummy variable for the region.Footnote 65 To account for oil-exporting countries, which tend to hold a high level of reserves for orthogonal reasons, we included a dummy variable for oil exporters. Finally, in the last column, we reran the analysis including country fixed effects to account for any unobserved country-specific factors that might affect the level of reserves.Footnote 66 Since fixed effects in Tobit models tend to produce biased estimates, we use OLS for this specification.Footnote 67 In all cases, imf influence remains negatively and significantly associated with reserves.Footnote 68
We predict that expectations of favorable treatment by the IMF generate moral hazard. One manifestation of this is that countries forgo self-insurance, holding lower levels of foreign reserves. Countries may also pursue more risky policies, such as loosening financial regulations or promoting short-term capital inflows. Expectations of greater IMF leniency will also affect the risk assessments of private financial institutions, which may lend more aggressively to a country believed to be well-positioned vis-à-vis the IMF. The upshot is that heightened risk taking and insufficient self-insurance should make such countries more likely to experience banking and currency crises.
We therefore examine whether higher IMF influence leads to the more frequent incidence of crises. The banking and currency crisis variables we use are dichotomous, with 1 indicating any occurrence of a crisis during the relevant five-year period, and 0 otherwise.Footnote 69 Because the dependent variable is dichotomous, we use logit specifications. Across all models, we include country and time period fixed effects to account for unobserved sources of country-specific and temporal variation in crisis incidence.
Table 4 presents the results. The first and second models include only the key independent variable, imf influence. For both banking and currency crises, imf influence is positively associated with crisis incidence. The third and fourth columns show that this relationship remains robust to the inclusion of macroeconomic controls considered earlier.Footnote 70 Finally, the fifth and sixth columns include additional control variables that are potentially endogenous to moral hazard concerns as discussed earlier. In all model specifications, imf influence is associated with a higher likelihood of financial crises.
Notes: Models include time period and country fixed effects. Observations are in five-year increments (e.g., 1980–1985), with crises coded as 1 if any crisis occurs during the period. All independent variables are measured at the beginning of the five-year period. Asterisk denotes a coefficient at least two standard errors removed from 0.
As a robustness check, we reran the specifications after recoding the dependent variable as “twin crises,”Footnote 71 cases in which banking and currency crises occur simultaneously. Similarly, we considered whether imf influence is associated with the incidence of “financial crises” more broadly defined, by coding a dummy variable for the incidence of any crisis type examined by Reinhart and RogoffFootnote 72—banking crisis, currency crisis, sovereign debt default, inflation crisis, and market crashes. imf influence is positively and significantly associated with financial crises according to these alternative indicators.Footnote 73 We also included several domestic political variables that have been found to be meaningful predictors of currency crises in existing work—democracy, divided government, and turnover.Footnote 74 These alternative specifications did not alter the substantive results: the relationship between imf influence and the incidence of crises remained positive and statistically significant.
Finally, as an additional robustness check, we reran our empirical models using bank lending from financial institutions in the United States and major European countries as a proxy for expected influence over the IMF. Bank exposure is a conventional proxy for IMF influence widely used in existing literature.Footnote 75 By using the variable in lieu of our PCA variable, we can demonstrate that our findings are not driven by the use of a “new” independent variable to capture a country's expected influence over the IMF.
Bank exposure is measured as the bank lending a country receives from a specific source as recorded by the BIS. For European countries, we use combined lending from France, Germany, and the UK since these are the largest international lenders in Europe and likely to hold the most sway in the IMF.Footnote 76 Because the US and major European countries exert asymmetrical influence over the IMF, we expect that moral hazard should be a greater problem among countries receiving large amounts of bank lending from the US and Europe. This should be reflected in a lower tendency to self-insure through reserve holdings, as well as more frequent incidence of financial crises. We also include banking lending from Japan, which has traditionally been the other major source of international bank lending, but is a country that has been historically underrepresented and unable to exert influence within the IMF.Footnote 77 Because of this, we do not expect high exposure from Japanese financial institutions to generate moral hazard.
The results, summarized in the online appendix (Table A5 and A6), provide additional support for our theoretical expectations that IMF moral hazard is distributed unevenly across the world economy. Countries with strong financial ties to the US and Europe tend to hold a lower level of reserves and have more frequently experienced crises. In contrast, bank exposure from Japan is not meaningfully associated with reserves or the incidence of crises. We conducted all robustness checks described earlier in reference to Table 3 and Table 4, and the substantive results remained unchanged.Footnote 78
Causal Mechanisms: Taiwan
In this section, we evaluate our proposed causal mechanisms by leveraging Taiwan's unique history with the IMF. Taiwan is an extreme example of the biased international insurance system created by the politics of the IMF. Taiwan was expelled from the IMF in April 1980 against its will for exogenous political reasons and it is the only major economy that is not an IMF member.Footnote 79 Taiwan is a useful counterfactual case because it cannot expect any support from the IMF despite its deepening integration with the world economy. We show that Taiwan's expulsion from the IMF led to a policy shift consistent with our theoretical predictions: Taiwanese authorities sharply increased international reserves and maintained conservative regulatory policies to shield its economy from potential crises.
Taiwan's Expulsion from the IMF
One of the challenges of causal inference when considering IMF moral hazard is the nature of the institution's membership. IMF membership is now essentially universal, with minor exceptions such as Cuba, North Korea, and several microstates.Footnote 80 Most changes in membership status have occurred as a result of self-selection, making it probable that changes in reserves associated with membership status are at least in part caused by domestic policy changes. For example, a large influx of new members occurred after the end of the Cold War, when post-communist transition coincided with IMF membership.Footnote 81 Changes in relations vis-à-vis the IMF tend to be gradual, reflecting the evolution of voting power or diplomatic and economic ties with influential states.
Taiwan provides an important opportunity to evaluate our proposed causal mechanisms. Taiwan is the only major economy that is not an IMF member. This is a legacy of diplomatic competition with the People's Republic of China, which resulted in Taiwan's expulsion from the IMF in April 1980. Under the “One China” principle of the People's Republic of China,Footnote 82 Chinese entry into the IMF was predicated on the exit of Taiwanese representatives. For this reason, Taiwan is a unique counterfactual case of a major, globally integrated economy without any prospect of being subject to IMF moral hazard.
Taiwanese expulsion from the IMF in April 1980 presents several attractive features for the purposes of causal inference. First, Taiwan's exit represents a sharp disjuncture, immediately and dramatically altering the country's relationship with the IMF. Prior to its expulsion, Taiwan enjoyed a relatively privileged position within the IMF: though not large in absolute terms, Taiwan was overrepresented according to voting power and share of IMF staff,Footnote 83 and it enjoyed close political and economic ties with the United States, which exercises outsized informal influence.Footnote 84 After April 1980, Taiwan could expect no help from the IMF in the event of financial difficulties. As George P. Nicoletopoulos, the director of the IMF's legal department, noted on the eve of Taiwan's departure, expulsion meant that “all official relations under the Articles of Agreement with the Taiwanese authorities would cease.”Footnote 85 Informal ties have also been largely precluded by subsequent Chinese intransigence. US government officials of the American Institute in Taiwan, the de facto embassy, confirm that there are no arrangements, formal or informal, for an IMF bailout of Taiwan in the event of a financial crisis.Footnote 86
Second, the expulsion of Taiwan was involuntary and hence not subject to self-selection. Taiwanese authorities preferred to remain IMF members if possible, but they were removed by a vote of the executive board, which switched Taiwan's credentials to China.Footnote 87 Thus, Taiwan's change in status from an IMF member to nonmember is not attributable to any domestic policy shift. Taiwan's shift from import-substitution industrialization to export-oriented industrialization, a domestic policy change that might have plausibly led to greater reserve accumulation, took place much earlier in 1958–1960.Footnote 88
Third, the disposition and precise timing of Taiwan's expulsion were uncertain ex ante. China had displaced Taiwan in major United Nations agencies in the early 1970s by securing majority support, primarily among developing countries.Footnote 89 In 1973, Chinese Minister of Foreign Affairs Ji Pengfei sent a formal notice to the heads of the IMF and World Bank requesting the expulsion of the “KMT counterrevolutionary clique.”Footnote 90 However, the weighted voting rules of the IMF gave large economies, such as the United States, leverage to resist the credentials change.Footnote 91 In addition, Chinese policymakers were somewhat ambivalent about membership—they feared a lack of influence under the weighted voting scheme and the economic obligations that would come with IMF membership.Footnote 92 Diplomatic negotiations dragged on through the 1970s. As late as March 1980, less than a month before Taiwan's ultimate expulsion, US officials were engaged in negotiations with China to continue Taiwan's membership based on the “Olympic Model” in which Taiwanese membership would be maintained under a different name and national symbols.Footnote 93 It was possible that Taiwan's membership would continue as it ultimately did in the Asian Development Bank, where resistance from the US and Japan resulted in a joint membership arrangement in 1986 that renamed Taiwan as “Taipei China.”Footnote 94
Synthetic Control
We use the synthetic control method to examine the trajectory of international reserves in Taiwan before and after expulsion from the IMF. Synthetic control overcomes some of the problems associated with comparative case studies through data-driven construction of a control case that closely resembles the treated case of interest.Footnote 95 The method was first used to analyze the economic impact of terrorism in the Basque country,Footnote 96 and has since been applied to examine the effects of a wide range of political changes such as German reunificationFootnote 97 and economic liberalization.Footnote 98 In this case, “synthetic Taiwan” represents the weighted average of potential control countries, with weights chosen to closely reproduce the values of a set of predictors of international reserves during the decade prior to IMF expulsion (1970–1979). We can then compare the evolution of reserves in Taiwan and synthetic Taiwan during the subsequent decade (1980–1990).
Our expectation is that Taiwan's reserves should increase sharply after its expulsion from the IMF in 1980 compared to the trajectory for synthetic Taiwan. Taiwan's expulsion shifted its status from a relatively privileged member of the IMF to maximal absence of privilege, that is, no expectation of IMF assistance whatsoever. This change should be associated with a buildup of international reserves as IMF moral hazard was abruptly removed.
As with earlier analyses, we use international reserves as a share of GDP as the dependent variable. We obtained substantively similar results by using reserves in months of imports and the absolute level of reserves in current US dollars. As control cases, we include all countries in the international system for which data on reserves and the relevant control variables are available during the time period of interest. As predictor variables, we use the control variables from the earlier panel analysis: gdp per capita, gdp, the gdp growth rate, the inflation rate, exports, imports, indicator for pegged exchange rate regime, index for currency valuation, a dummy for OECD countries, and a dummy for East Asian countries. We also include prior values of the dependent variable—international reserves in 1979, 1975, and 1970—following the recommendation of Abadie, Diamond, and Hainmueller.Footnote 99 The results are highly robust to alternative selections and combinations of control variables.Footnote 100
As Figure 1 shows, international reserves in Taiwan and synthetic Taiwan closely resemble one another until 1980, the year when Taiwan was expelled from the IMF. Subsequently, a large gap opens up, with Taiwan's reserves increasing dramatically while reserves for synthetic Taiwan remain flat. In the online appendix we show that the predictor means are well balanced and provide a full list of country weights: synthetic Taiwan most heavily weights Thailand (0.42), South Korea (0.33), and Turkey (0.17).
The change in Taiwan's reserves during this period was substantively significant. In 1980, Taiwan's reserves were $1.4 billion US dollars, equivalent to 1.0 month of imports, considerably below the global average of 3.8 months of imports. By 1990, Taiwan's reserves had increased to $72.4 billion, or about 13.2 months of imports, while the global average was essentially unchanged at 3.8 months of imports. No country in the world increased reserve holdings as much as Taiwan during this period: by 1991, Taiwan's reserve holdings exceeded much larger economies such as Japan, the United States, and Germany to become the largest in the world in absolute terms.
We performed several placebo tests to confirm that the movement of Taiwan's reserves after IMF expulsion stands out in international comparison. First, we performed a permutation test in which synthetic control estimates are derived for all control countries as if they were treated in 1980. This allows us to guard against simultaneous shocks that might have affected the reserve accumulation behavior of countries in 1980. The results are presented in Figure 2. For all countries analyzed, the figure depicts the gap in reserves between the “treated” country and the synthetic control. The solid line is Taiwan. As the figure shows, Taiwan clearly stands out in comparison to all countries in the sample: there is no other country that exhibits a similar, sustained increase in reserves compared to the synthetic control after 1980. In statistical terms, the likelihood that Taiwan's reserve accumulation occurred by chance is less than 2 percent.Footnote 101
We also performed an additional placebo test by assigning 1971 as the treatment year. In 1971, Taiwan lost its credentials in the United Nations to China, an event that marked the beginning of international isolation. If international isolation, rather than the loss of IMF membership, was the driver of Taiwan's reserve accumulation, we would expect Taiwan's reserves to start increasing at this point. However, the analysis provides no evidence for this: Taiwan's reserves did not increase in comparison to synthetic Taiwan when the treatment year is set to 1971. These results are available in the online appendix.
Another potential explanation for Taiwan's reserve accumulation is its evolving relationship with the United States. The US initiated “ping-pong diplomacy” with China in 1971, gradually improved informal bilateral relations with the mainland, and switched formal diplomatic recognition from Taiwan to China in January 1979. However, it is highly unlikely that a change in bilateral relations with the US alone precipitated Taiwan's shift in reserve accumulation behavior. For one, severance of formal diplomatic relations in January 1979 was followed by the April 1979 Taiwan Relations Act, which assured that US–Taiwan relations would continue largely unchanged. The act established a de facto US embassy (the American Institute in Taiwan) and maintained the validity of all previous US–Taiwan economic agreements. Economic relations between Taiwan and the US remained virtually unchanged.Footnote 102
We are limited to yearly increments for the synthetic control method because of data availability for the control variables. However, the raw data for Taiwan's reserves are available on a monthly basis. Figure 3 depicts Taiwan's reserves in current US dollars for every month between January 1975 and January 1985. We use the absolute value of reserves because data for GDP and imports are unavailable on a monthly basis. The data are log transformed to allow comparisons of percentage changes during the time period depicted. The figure clearly shows a shift in Taiwan's reserve accumulation immediately after April 1980, the month in which Taiwan was expelled from the IMF. There is no comparable shift associated with any other month depicted, including January 1979, when the US transferred diplomatic recognition to China.
Consistent with our theoretical premises, Taiwan has adopted an exceptionally conservative policy of self-insurance after being expelled from the IMF. Despite its relatively small economy, Taiwan's international reserves have been among the largest in the world since the mid-1980s: they are currently the fifth largest in absolute terms, behind only China, Japan, Saudi Arabia, and Switzerland.Footnote 103 In addition, the reserves have been invested extremely conservatively: Taiwan has no sovereign wealth fund and has allocated its reserves primarily in US Treasuries and gold.Footnote 104
Taiwan has also pursued relatively conservative policies regarding financial liberalization and capital inflows.Footnote 105 Taiwan's conservative regulatory policies and large stock of reserves are frequently cited as reasons for how it was able to weather the 1997–98 Asian crisis and 2008 global financial crisis relatively unscathed.Footnote 106 Taiwanese government officials indicate that this behavior is motivated by the understanding that no international organization will come to Taiwan's rescue in the event of a crisis.Footnote 107 In the words of Taiwan's former finance minister, Paul Chiu, “We are not a member of the IMF or World Bank, so we have to rely on our own resources.”Footnote 108
Taiwan's reserve accumulation is often attributed to its export orientation, though some scholars also recognize the precautionary motivations associated with its lack of membership in the IMF.Footnote 109 The two motivations are somewhat intertwined. Taiwanese authorities accumulated reserves by intervening heavily in foreign exchange markets, holding down the value of the New Taiwan Dollar and running large current account surpluses.Footnote 110 However, it is highly unlikely that export orientation alone accounts for Taiwan's reserve accumulation since 1980. For one, Taiwan's shift to export-oriented industrialization happened much earlier in 1958–1960 than its shift toward reserve accumulation, which took place in 1980.Footnote 111 In addition, among other East Asian export-oriented economies often compared to Taiwan, reserve accumulation was much more modest during the period when Taiwan sharply increased its reserves.Footnote 112 Reserve accumulation in the rest of the region took off primarily after the Asian Financial Crisis, when IMF intervention was widely perceived as unresponsive to regional interests.Footnote 113
Conclusion
Political imbalances within the IMF have important economic consequences for the global economy. Because IMF decision making is heavily politicized and biased toward the interests of a subset of influential states, the international system is effectively governed by a biased insurance mechanism. This bias produces asymmetrical moral hazard, encouraging some countries to pursue risky policies while countries lacking influence are compelled to pursue aggressive self-insurance through the accumulation of international reserves.
We analyzed a panel data set covering 1980 to 2010 and found that countries expected to exercise strong influence over the IMF tend to receive favorable treatment from the institution. Crucially, these countries also exhibit distinct characteristics of moral hazard: relatively low levels of reserves and frequent currency crises. In contrast, countries with limited leverage over the IMF tend to pursue self-insurance, accumulating precautionary reserves and experiencing crises less frequently. To evaluate our causal claims, we leveraged Taiwan's unique status vis-à-vis the IMF. Taiwan's expulsion from the institution in 1980 created an abrupt disjuncture, shifting the country from a relatively privileged position in the institution to nonmembership, under which no future support could be expected. As predicted, this led Taiwanese authorities to pursue aggressive self-insurance, rapidly accumulating reserves and maintaining conservative financial policies.
Our findings have important implications for contemporary debates over global economic imbalances. In recent years, global economic imbalances have become an increasingly salient political and economic issue. The fixed and undervalued exchange rates, reserve accumulation, and current account surpluses of several developing countries, particularly in East Asia—coupled with a large US current account deficit—became widely known as “Bretton Woods II,” a new iteration of the post-World War II international monetary order.Footnote 114 Donald Trump rose to power in the United States promising to revive the country by reversing persistent trade deficits. The pattern of reserve accumulation in recent decades represents a perverse flow of capital from developing countries—where returns on invested capital ought to be higher—to developed states.Footnote 115 Most existing explanations for global imbalances have focused on underlying economic factors.Footnote 116 Our findings suggest that greater attention needs to be paid to political imbalances within the IMF: countries that cannot expect generous treatment by the IMF have a stronger propensity to accumulate precautionary international reserves, contributing to global economic imbalances.
Our findings also suggest an asymmetric impact of IMF lending on the activities of internationally active financial institutions. One of the implications of our quantitative analysis is that the IMF is more likely to bail out highly exposed Western financial institutions on generous terms. In domestic financial markets, large banks that are deemed “too big to fail” receive significant advantages, including higher valuationsFootnote 117 and lower risk premiums.Footnote 118 As we have asserted, “too big to fail” in the international context is a function of influence over IMF policymaking. As such, Western financial institutions enjoy unfair competitive advantages in international lending. For the past several decades, Japanese financial institutions have been the primary non-Western lenders in international markets and hence most likely to face the adverse consequences of this asymmetry. As other countries develop economically and expand their international financial activities, this issue is likely to become increasingly salient.
Our account demonstrates that contestation over representation and influence in the IMF is not simply a matter of national ego or prestige. The IMF has recently pursued a series of reforms to realign its quota shares and formulas. The fourteenth annual review, which came into effect in 2016, shifted about 6 percent of quota shares in favor of underrepresented countries.Footnote 119 However, these measures are modest in their formal effectFootnote 120 and do little to remedy informal biases in IMF governance. These disparities are set to widen further as economic growth in developing countries exceeds that of overrepresented Western countries. The broader consequences of political bias in the IMF will remain an important topic for ongoing research.
