In this paper, I present a theory of dynamic economic growth, business cycles, and asset pricing that integrates (1) Marx's idea (and emphasized by Klein) of a two-class heterogeneity of the ownership structure of physical capital and human capital in a capitalist society, (2) Keynes' idea of...

I argue that progress in understanding economic development (as in other branches of economics)must come from the investigation of mechanisms; the associated empirical analysis can usefully employa wide range of experimental and non-experimental methods. I discuss three different areas of...

It is widely acknowledged that the recent generation of DSGE models failed to incorporate many of the liquidity and financial accelerator mechanisms revealed in the global financial crisis that began in 2007. This paper complements the papers presented at the 2009 BIS annual conference focused...

This paper uses mortgage data to construct a measure of terms on which households access to externalfinance, and relates it to consumption at both the aggregate and cohort levels. The Household ExternalFinance (HEF) index is based on the spread paid by risky borrowers in the mortgage market....

This paper uses a unique data set on more than 600,000 mortgagecontracts to estimate a credit supply function which allows for risk-heterogeneity. Non-linearity is modeled using quantile regressions. Wepropose an instrumental variable approach in which changes in the taxtreatment of housing...

Strong procyclical fluctuations in the durable production are the most prominent featureof the empirical response to monetary shocks. This paper investigates the role of preferencesin matching this feature of the data in a two-sector sticky price model with flexibly priceddurables. The reaction...

We propose a simple and powerful method for determining the transition processin continuous-time DSGE models under Poisson uncertainty numerically. The idea isto transform the system of stochastic dierential equations into a system of functionaldierential equations of the retarded type. We then...

We characterize how public insurance schemes are constrained by hidden financialtransactions. When non-exclusive private insurance entails increasing unit transaction costs,public transfers are only partly offset by hidden private transactions, and can influenceconsumption allocation. We show...

The large spread between equity returns and risk free rates observed in most stock markets (the "equity premium puzzle") has been subject of intense debates. Two main families of models claim to solve this puzzle: habit formation models and loss aversion models. The goal of this paper is to...

This paper studies the Cass-Koopmans-Ramsey model of optimal economic growth with a representative agent whose preferences for consumption can be gradually varied between the standard CES case and Kahneman and Tversky's prospect utility. The numerical analysis of a specific parametrization shows...
