By Charles Hodgson

American Economic Journal: Microeconomics, November 2023

Manufacturers of durable goods can encourage consumers facing transaction costs to upgrade by accepting used units as trade-ins. These "buyback schemes" increase demand for new units, but increase the supply of used units if trade-ins are resold. I invest...

By John A. Clithero, Jae Joon Lee, and Joshua Tasoff

American Economic Journal: Microeconomics, November 2023

The canonical direct-elicitation approach for measuring individuals' valuations for goods is the Becker-DeGroot-Marschak procedure, which generates willingness-to-pay (WTP) values that are imprecise and systematically biased. We show that enhancing elicit...

By Kyle Bagwell and Seung Hoon Lee

American Economic Journal: Microeconomics, November 2023

We consider the single-sector version of the Melitz-Ottaviano model of monopolistic competition with heterogeneous firms. We characterize the first-best and market allocations. We find that the market provides the first-best level of entry but too little ...

We present a learning-based selection argument for Linear Bayesian Nash equilibrium in a Walrasian auction. Endowments vary stochastically; traders model residual supply as linear, estimate its slope from past trade data, and periodically update these est...

A Model of Sequential Crisis Management

By Fei Li and Jidong Zhou

American Economic Journal: Microeconomics, November 2023

We propose a model of how multiple societies respond to a common crisis. A government faces a "damned-either-way" policymaking dilemma: aggressive intervention contains the crisis, but the resulting good outcome makes people skeptical about the costly res...

American Economic Review, November 2023

We study a problem in which policymakers need to screen self-selected individuals by unobserved heterogeneity in social welfare gains from a policy intervention. In our framework, the marginal treatment effects and marginal treatment responses arise as ke...
