Moral values influence individual behavior and social interactions. A specially significant instance is the case of moral values concerning work effort. Individuals determine what they take to be proper behaviour and judge the others, and themselves, accordingly. They increase their esteem -and...

To help explain differences between the US and EU "social contracts" as well as other cultural differences, we present a model of rational voting over redistribution where individual attitudes toward others are endogenously determined. Individuals differ in their productivities and their degree...

We examine the interactions between individual behavior, sentiments and the social contract in a model of rational voting over redistribution. Agents have moral work values. Individuals self-esteem and social consideration of others are endogenously determined comparing behaviors to moral...

We explore a view of the crisis as a shock to investor sentiment that led to the collapse of a bubble or pyramid scheme in financial markets. We embed this view in a standard model of the financial accelerator and explore its empirical and policy implications. In particular, we show how the...

We study a dynamic economy where credit is limited by insufficient collateral and, as a result, investment and output are too low. In this environment, changes in investor sentiment or market expectations can give rise to credit bubbles, that is, expansions in credit that are backed not by...

We develop a stylized model of economic growth with bubbles. In this model, financial frictions lead to equilibriumdispersion in the rates of return to investment. During bubbly episodes, unproductive investors demand bubbles while productive investors supply them. Because of this, bubbly...

This paper argues that in the presence of intersectoral input-output linkages, microeconomic idiosyncratic shocks may lead to aggregate fluctuations. In particular, it shows that, as the economy becomes more disaggregated, the rate at which aggregate volatility decays is determined by the...

Over the past two decades, technological progress in the United States has been biased towards skilled labor. What does this imply for business cycles? We construct a quarterly skill premium from the CPS and use it to identify skill-biased technology shocks in a VAR with long-run restrictions....
