Married men work substantially more hours than men who have never been married, even after controlling for observables. Panel data reveal that much of this gap is attributable to an increase in work in the years leading up to marriage. Two potential explanations for this increase are: (i) men...

Migration plays a key role in city finances with every new entrant reducing debt per person and every exit increasing it. We study the interactions between regional borrowing, migration, and default from empirical, theoretical, and quantitative perspectives. Empirically, we document that...

We use a detailed establishment-level dataset from Germany to document a new dimension of firm heterogeneity: large firms spend a higher share of their wage bill on immigrants than small firms. We show analytically that ignoring this heterogeneity in the immigrant share leads to biased...

We examine a model of the size distribution and growth of firms whereby firms learn about idiosyncratic productivity parameters. Aggregate shocks, by adding noise to learning at the firm level, can produce differentiated response across firms with their reactions depending on the position of the...

We use a very standard life-cycle growth model, in which individuals have a labor-leisure choice in each period of their lives, to prove that an optimizing government will almost always find it optimal to tax or subsidize interest income. The intuition for our result is straightforward. In a...

Portfolio choice models counter factually predict (or advise) almost universal equity market participation and a high share for equity in wealth early in life. Empirically consistent predictions have proved elusive without participation costs, informational frictions, or non standard...

Data reveal that individuals experience a high number of occupational switches. Over 40% of high school graduates transition between white and blue collar occupations more than once between the ages of 18 and 28. This paper develops a life cycle model of occupational choices based on workers...

The standard theory of household-portfolio choice is hard to reconcile with the following facts: (i) Households hold a small amount of equity despite the higher average rate of return. (ii) The share of risky assets increases with the age of the household. (iii) The share of risky assets is...
