is characterized by countercyclical default risk. In this paper we develop a quantitative dynamic stochastic small open economy model with incomplete markets,endogenous fiscal policy and sovereign and private sector default where public expenditures and tax rates are optimally procyclical. The...

We incorporate house price risk and mortgages into a standard incomplete market (SIM) model. We calibrate the model to match U.S. data, and we show that the model also accounts for non-targeted features of the data such as the distribution of down payments, the life-cycle prole of homeownership,...

How important is financial development for economic development? A costly state verification model of financial intermediation is presented to address this question. The model is calibrated to match facts about the U.S. economy, such as intermediation spreads and the firm-size distribution for...

This paper considers the problem of optimal unemployment insurance (UI) in a repeated moral hazard framework. Unlike existing literature, unemployed individuals can secretly participate in a hidden labor market. This extension modifies the standard problem in three dimensions. First, it imposes...

Consumer bankruptcies rose sharply over the last 20 years in the U.S. economy. During the same period, there was impressive technological progress in the information sector. This paper provides a theory to understand and quantify the role of improvements in information technologies in consumer...

To address how technological progress in financial intermediation affects the economy, a costly-state verification framework is embedded into the standard growth model. The framework has two novel features. First, firms differ in the risk/return combinations that they offer. Second, the efficacy...

We study the sovereign default model that has been used to account for the cyclical behavior of interest rates in emerging market economies. This model is often solved using the discrete state space technique with evenly spaced grid points. We show that this method necessitates a large number of...
