In this paper we consider a risk averse worker who is moving back and forth between employment and unemployment; layoffs are random and beyond the worker s influence, while the re-employment chance is directly affected by search effort. We characterize the worker s optimal savings and job-search...

This paper explores the role of marriage when markets are incomplete so that individuals cannot diversify their idiosyncratic labor income risk. Ceteris paribus, an individual would prefer to marry a hedge (i.e. a spouse whose income is negatively correlated with her own) as it raises her...

The new information and communication technology, ICT, induces households to take over tasks from firms and government agencies, using tools and systems provided by these very same organizations. The result is often joint production activities. We argue that the importance of ICT for the...

Why do some U.S. states have higher levels of marital formation than others? This paper introduces an economic model wherin a state s representative individual may choose to marry in order to diversify his or her idiosyncratic income risk. The paper demonstrates that such a diversification...

This paper studies within-family decision making regarding investment in income protection for surviving spouses. A change in US pension law (the Retirement Equity Act of 1984) is used as an instrument to derive predictions both from a simple Nash-bargaining model of the household and from the...

We develop a behavioral macroeconomic model in which agents use simple but biased rules to forecast future output and inflation. This model generates endogenous waves of optimism and pessimism ("Animal Spiritsʺ) that are generated by the correlation of biased beliefs. We contrast the dynamics...

The deterrent effect of law enforcement rests on the link between the actual and the perceived detection risk. We study the role of word of mouth for this linkage. Our approach makes use of micro data on compliance with TV license fees allowing us to distinguish between households who have been...

We derive the optimal monetary policy in a sticky price model when private agents follow adaptive learning. We show that this slight departure from rationality has important implications for policy design. The central bank faces a new intertemporal trade-off, not present under rational...

We study a general static noisy rational expectations model, where investors have private information about asset payoffs, with common and private components, and about their own exposure to an aggregate risk factor, and derive conditions for existence and uniqueness (or multiplicity) of...

Capitalism is characterized by booms and busts. Periods of strong growth in output alternate with periods of declines in economic growth. Every macro-economic theory should attempt to explain these endemic business cycle movements. In this paper I present two paradigms that attempt to explain...
