To estimate the dynamic effects of an absorbing treatment, researchers often use two-way fixed effects regressions that include leads and lags of the treatment. We show that in settings with variation in treatment timing across units, the coefficient on a given lead or lag can be contaminated by effects from other periods, and apparent pretrends can arise solely from treatment effects.
We examine simultaneously the effects of real-exchange-rate movements and tariff reductions on plant death in canadian manufacturing industries between 1979 and 1996. Consistent with the implications of recent international trade models with heterogeneous firms, we find that the impact of exchange-rate movements and tariff cuts on exit is heterogeneous—particularly pronounced among least.

This article reviews macroeconomic models with heterogeneous households. A key question for the relevance of these models concerns the degree to which markets are complete. This is because the existence of complete markets imposes restrictions on (i) how much heterogeneity matters for aggregate phenomena and (ii) the types of cross-sectional distributions that can be obtained.

By allowing for differences among individuals where previous analyses restricted attention to homogeneous labor, i am able to understand the impact of such a consideration on issues of optimal policy and potential equilibria.
The goal of this paper is to simultaneously unbundle two interacting reduced-form building blocks of traditional macroeconomic models: the representative agent and the aggregate production function.

Broadly speaking, models with heterogeneous agents fall into the category of agent-based computational economics (ace) if the agents have adaptive expectations, or into the category of dynamic stochastic general equilibrium (dsge) if the agents have rational expectations. Dsge models with heterogeneneous agents are especially difficult to solve, and have only recently become a widespread topic of research; most early dsge research instead focused on representative agent models.
We model situations in which a principal offers contracts to a group of agents to participate in a project. Agents' benefits from participation depend on the identity of other participating agents. We assume heterogeneous externalities and characterize the optimal contracting scheme. We show that the optimal contracts' payoff relies on a ranking, which arise from a tournament among the agents.
