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....

We study the macroeconomic effects of international trade policy by integrating a Hecksher-Ohlin trade model into an optimal-growth framework. The model predicts that a more open economy will have higher factor productivity. Furthermore, there is a "selective development trap" to which countries...

We develop a two-country, two-currency, search-theoretic model of monetary exchange, extending previous such models by endogenizing prices using bargaining theory. We analyze features of the environment that make it more likely that a given money circulates internationally. We show the value of...

The Doha Round differs from previous multilateral rounds since a number of participating countries are negotiating and implementing bilateral and regional free trade agreements (FTAs) at the same time as they are negotiating multilaterally. The standard arguments against FTAs involve that they...

Recently, the search-theoretic approach to monetary economics has been generalized to incorporate bilateral bargaining theory in order to determine the purchasing power of money endogenously (the first-generation of models in this literature essentially assume that prices are fixed exogenously)....

I study a version of the Williamson-Wright (1994) model that results from ruling out direct barter. Although one can no longer argue that the value of money comes exclusively from private information, one can use the simplified model to address a variety of other issues. In particular, one can...
