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 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...

Central to Bitcoin is its independence from any institution or government, allowing anyone to engage in a direct transaction at a low cost. So, what exactly is it, and how does it work?

Do developed financial markets lead to economic growth or result from it? While some economists argue for the latter, the author maintains that financial markets—despite their shortcomings of late—are an essential ingredient for an economy to grow in the long run.

We propose a simulated maximum likelihood estimator for dynamic models based on non-parametric kernel methods. Our method is designed for models without latent dynamics from which one can simulate observations but cannot obtain a closed-form representation of the likelihood function. Using the...

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 1999–2002 when the International Monetary Fund (IMF) instituted new...

We develop a model of retirement and human capital investment to study the effects of tax and retirement policies. Workers choose the supply of raw labor (career length) and also the human capital embodied in their labor. Our model explains a significant fraction of the US-Europe difference in...

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...

This paper develops a theory of debt management in which government financing decisions have distributional consequences. We consider a constant aggregate endowment economy in which the government finances exogenous stochastic public spending needs with uniform lump sum taxes and...
