We study the evolution of trade policies over time and across countries. We consider a model in which own and neighbors' past experiences influence policy choices, through their effect on policymakers' beliefs. We estimate the model using a large panel of countries. We find that there is a...

In Bassetto with Sargent (2004) and Bassetto and Lepetyuk (2007), I developed a model that can be used to quantitatively assess the consequences of departures from Ricardian equivalence on the mix of public goods provided by the government. Those papers assume that mobility is exogenous and that...

We estimate an empirical model of consumption disasters using a new panel data set on consumption and output for over 20 countries and more than 100 years. The model allows for permanent and transitory effects of disasters, nesting both unit root and trend stationary consumption growth. We...

In this paper, we develop a tractable model of the labor market featuring on-the-job search and aggregate fluctuations.

To explore the quantitative implications that AIDS has for the development path of the Sub- Saharan African economies, I extend a standard theory of economic development that reproduces the process of industrialization, Hansen and Prescott (2002), with a population model that relates the age...

Financial crises are costly. In the recent crisis in Argentina, for example, from the onset of sovereign debt repayment difficulties at the end of 2000 until the beginning of 2002, real GDP dropped by almost 20%. A simple aggregate growth accounting exercise suggests that a large part of this...

The paper presents a general equilibrium model with search on the job. Workers differ in terms of skill levels and firms differ in terms of productivity. Depending on the production function characteristics, sorting in matching may occur. The paper estimates the model on Danish match data and...

Educational attainment varies greatly across countries and within countries over time. This paper asks whether the variation in education is primarily due to structural change or to within industry skill upgrading. The main finding is that within industry variation accounts for at least 2/3 of...
