Why are financial crises associated with a sustained rise in unemployment? We develop a tractable model with frictions in both credit and labor markets to study the aggregate and micro-level implications of a credit crunch--i.e., a tightening of collateral constraints. When we simulate a credit...

We provide a quantitative evaluation of the aggregate and distributional impact of microfinance or credit programs targeted toward small businesses. We find that the redistributive impact of microfinance is stronger in general equilibrium than in partial equilibrium, but the impact on aggregate...

We quantify the role of financial frictions and the initial misallocation of resources in explaining development dynamics. Following a reform that triggers efficient reallocation of resources, our model economy with financial frictions converges slowly to the new steady state--it takes twice as...

Why doesn't capital flow into fast-growing countries? In this paper, we provide a quantitative framework incorporating heterogeneous producers and underdeveloped domestic financial markets to study the joint dynamics of total factor productivity (TFP) and capital flows. When an unexpected...

Income differences across countries primarily reflect differences in total factor productivity (TFP). More disaggregated data show that the TFP gap between rich and poor countries varies systematically across industrial sectors of the economy: Poor countries are particularly unproductive in...

People's occupations have a significant amount of information about their wages. However, because people - especially young workers - go through multiple occupations and employment statuses during their working lives, we find that their occupations at a young age do not predict their lifetime...

Aggregate productivity growth in the U.S. has slowed down since the 2000s. We quantify the importance of differential productivity growth across occupations and across industries, and the rise of computers since the 1980s, for the productivity slowdown. Complementarity across occupations and...

We analyze the effect of technological change in a novel framework that integrates an economy's skill distribution with its occupational and industrial structure. Individuals become managers or workers based on their managerial vs. worker skills, and workers further sort into a continuum of...

We review the empirical evidence on microfinance and asset grants to the ultra poor or microentrepreneurs, and assess our ability to account for this evidence using quantitative theory. Properly executed, these interventions can help segments of the population increase their income and...

This paper studies whether transparency (measured by accuracy and frequency of macroeconomic information released to the public) leads to lower borrowing costs in sovereign bond markets. We analyze the data generated during the 1999-2002 period, when the IMF instituted three new ways for...
