In this paper, I discuss the reasons for Costa Rica's economic performance over the last quarter of a century. Three complementary sets of policies (investments in human capital, careful stabilization, and an intelligent and aggressive integration into the world economy) explain the successful...

The empirical literature addressing links between the labor and the marriage markets is numerous and varied. Despite this, the theoretical (equilibrium) literature that explicitly links the two markets is less developed, particularly so with frictional markets. We build an equilibrium search...

This paper explores the development of public sector capabilities for Productive Development Policies in Costa Rica through four case studies of successful experiences, with less successful cases presented as counterfactuals. To some extent the paper tests the Technical, Organizational and...

This paper summarizes the findings of the recent Inter-American Development Bank book Two to Tango: Public-Private Collaboration Productive Development Policies, based on case studies of 25 productive development policies (PDPs) in five countries and discusses an additional example from Peru....

Inflation and unemployment are central issues in macroeconomics. While progress has been made on these issues recently using models that explicitly incorporate search-type frictions, existing models analyze either unemployment or inflation in isolation. We develop a framework to analyze...

We study the long-run relation between money, measured by inflation or interest rates, and unemployment. We first discuss data, documenting a strong positive relation between the variables at low frequencies. We then develop a framework where both money and unemployment are modeled using...

This paper studies dynamic general equilibrium models where firms trade capital in frictional markets. Gains from trade arise due to ex ante heterogeneity: some firms are better at investment, so they build capital in the primary market; others acquire it in the secondary market. Cases are...

We analyze agents' decisions to act as producers or intermediaries using equilibrium search theory. Extending previous analyses in various ways, we ask when intermediation emerges and study its efficiency. In one version of the framework, meant to resemble retail, middlemen hold goods, which...

Are financial intermediaries inherently unstable? If so, why? What does this suggest about government intervention? To address these issues we analyze whether model economies with financial intermediation are particularly prone to multiple, cyclic, or stochastic equilibria. Four formalizations...

We study economies where firms acquire capital in primary markets then retrade it in secondary markets after information on idiosyncratic productivity arrives. Our secondary markets incorporate bilateral trade with search, bargaining and liquidity frictions. We distinguish between full and...
