The impact of the privatisation of the commons remains a contested topic throughout the social sciences. Focusing on the Spanish case, this article reviews the literature and provides an overall assessment of this historical process based on recent research. Common lands appear to have been reasonably well managed and their dismantling did not foster agricultural productivity. Instead, the privatisation process negatively affected the economic situation of a large proportion of rural households and local councils, as well as deteriorating the stock of social capital. Therefore, the long-standing belief in the existence of a trade-off between equity and efficiency actually turns out to be misleading.

Literature published a decade ago reflected a pessimistic view of the market-oriented reforms that Latin America carried out in the 1980s and 1990s, and many politicians have attacked these reforms openly. Indeed, the atmosphere is so negative that it would be reasonable to assume that many of the reforms have been reversed. This paper will take a new look at the situation ten years later. Our argument is that the reforms have generally not been reversed. The reversal that has occurred has been with respect to privatisation in a few countries; negative public opinion is also concentrated on privatisation; and the reforms helped to enable Latin America to take advantage of favourable conditions leading to high growth in the 2004–8 boom period and a relatively strong performance during the 2008–9 crisis. While much remains to be done to raise growth and improve distribution, objective information about the reforms is needed when policies for the future are made.

In the 1940s, when the governor of Puerto Rico was still appointed by the U.S. president, a large state-owned enterprise (SOE) sector was established. Later, in 1948-1950, the island's first elected government privatised these SOEs. This paper documents both the creation of the SOE sector and its privatisation, and analyses the role played by ideology, political interests and economic concerns in the decision to privatise. Whereas ideological factors might have played a significant role in the building of the SOE sector, the privatisation process was driven by economic factors. In the cement sector, the competing private firm was more efficient and the SOEs in other sectors with no private competitors in the island showed permanent losses.
