This paper studies the effciency of financial intermediation through securitization with asymmetric information about the quality of securitized loans. In this theoretical model, I show that, in general, by providing reputation-based implicit recourse, the issuer of a loan can credibly signal...

This paper studies the efficiency of financial intermediation through securitization in a model with heterogeneous investment projects and asymmetric information about the quality of securitized assets. I show that when retaining part of the risk, the issuer of securitized assets may credibly...

Most industrialized countries confront at the same time an increasing life-span, low current birth rates and the retirement of the relatively large post World War II generation. This paper considers different policies as potential solutions to the implied funding problem of any Pay-As-You-Go...

From 1961 to 2007, U.S. aggregate hours worked increased and the labor wedge—measured as the discrepancy between a representative household׳s marginal rate of substitution and the marginal product of labor—declined substantially. The labor wedge is negatively related to hours and is often...

This paper characterizes the optimal combination of monetary policy and financial regulation in a quantitative infinite horizon model with a risk taking channel of monetary policy. The model economy is rich enough to match main characteristics of the U.S. economy and its financial sector, yet...

From 1980 until 2007, U.S. average hours worked increased by thirteen percent, due to a large increase in female hours. At the same time, the U.S. labor wedge, measured as the discrepancy between a representative household's marginal rate of substitution between consumption and leisure and the...

This paper analyzes the Canadian economy for the post-1960 period. It uses an accounting procedure developed in Chari, Kehoe, and McGrattan (2006). The procedure identifies accounting factors that help align the predictions of the neoclassical growth model with macroeconomic variables observed...

This paper examines the role of monetary policy in an environment with aggregate risk and incomplete markets. In a two-period overlapping-generations model with aggregate uncertainty, optimal monetary policy attains the ex-ante Pareto optimal allocation. This policy aims to stabilize the savings...

A view advanced in the aftermath of the late-2000s fi?nancial crisis is that lower than optimal interest rates lead to excessive risk taking by fi?nancial intermediaries. We evaluate this view in a quantitative dynamic model where interest rate policy affects risk taking through two channels....
