The European debt crisis shares features of the historical episodes of outright default on domestic public debt identified by Reinhart and Rogoff (2008) as a forgotten research subject. This paper proposes a theory of domestic sovereign default in which a government chooses debt and default...

This study undertakes a quantitative investigation of the distributional and welfare consequences of a sharp reduction in inflation in a small open economy. In the first chapter, a monetary model of a small open economy with uninsured idiosyncratic earnings risk is analyzed. In this model,...

In this paper I ask whether a model of firm capital accumulation with entry and exit calibrated to match the investment regularities of U.S. establishments is capable of generating the dependence of firrm dynamics on size and age. Firms face uncertainty in the form of idiosyncratic productivity...

the main business cycle regularities of emerging economies.

and productivity shocks similar to the assumptions in Chatterjee, Corbae, Nakajima, and Rios-Rull (2007, Econometrica).

First Draft: November 1, 2011 We propose a theory of endogenous firm-level volatility over the business cycle based on endogenous market exposure. Firms that reach a larger number of markets diversify market-specific demand risk at a cost. The model is driven only by total factor productivity...

Accepted for publication, Journal of Economic Dynamics and Control The aim of this paper is to quantify the role of formal-sector institutions in shaping the demand for human capital and the level of informality. We propose a firm dynamics model where firms face capital market imperfections and...

We develop a model of banking industry dynamics to study the quantitative impact of capital requirements on bank risk taking, commercial bank failure, and market structure. We propose a market structure where big, dominant banks interact with small, competitive fringe banks. Banks accumulate...

This paper develops a political economy model to evaluate how inequality affects policies via the political process. The model is an extension of Krusell and Rios-Rull (1999) to incorporate uninsured idiosyncratic risk to income. Using this framework, we evaluate the response of social insurance...

This paper uses a dynamic political economy model to evaluate whether the observed rise in wage inequality and decrease in median to mean wages can explain some portion of the relative increase in transfers to low earnings quintiles and relative increase in effective tax rates for high earnings...
