This article analyzes the effects of differential tax treatment of married and single individuals in the United States on marriage formation and composition, divorce, and labor supply. We develop a marriage-market model with search frictions and heterogeneous agents that is sufficiently rich to...

Differential tax treatment of married and single people is a key feature of the tax law in the US and other countries. We develop a matching model with search frictions to analyze the effects these tax provisions have on marriage formation and dissolution. Our main results are the following: (i)...

We define and explore no‐upward‐crossing (NUC), a condition satisfied by every parameterized family of distributions commonly used in economic applications. Under smoothness assumptions, NUC is equivalent to log‐supermodularity of the negative of the derivative of the distribution with...

We analyze how the agent's initial wealth affects the principal's expected profits in the standard principal–agent model with moral hazard.

We introduce and solve a new class of "downward-recursive" static portfolio choice problems. An individual simultaneously chooses among ranked stochastic options, and each choice is costly. In the motivational application, just one may be exercised from those that succeed. This often emerges in...

We study infinitely repeated games with perfect monitoring, where players have [beta]-[delta] preferences. We compute the continuation payoff set using recursive techniques and then characterize equilibrium payoffs. We then explore the cost of the present-time bias, producing comparative...
