Trade-ins and Transaction Costs in the Market for Used Business Jets

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...

Evaluating the Impact of Online Market Integration—Evidence from the EU Portable PC Market

By Néstor Duch-Brown, Lukasz Grzybowski, André Romahn, and Frank Verboven

American Economic Journal: Microeconomics, November 2023

We develop a framework to evaluate the impact of market integration, accounting for spillovers between multiple distribution channels. We adapt the standard random coefficients logit demand model to allow for substitution between channels and consumer arb...

By David J. Cooper and John H. Kagel

We compare behavior of two person teams with individuals in indefinitely repeated prisoner dilemma games with perfect monitoring. Team discussions are used to understand the rationale underlying these choices and how these choices come about. There are th...

Supervised Machine Learning for Eliciting Individual Demand

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 ...

Multihoming and Oligopolistic Platform Competition

By Tat-How Teh, Chunchun Liu, Julian Wright, and Junjie Zhou

American Economic Journal: Microeconomics, November 2023

We provide a general framework to analyze competition between any number of symmetric two-sided transaction platforms, in which buyers and sellers can multihome. We show how key primitives such as the number of platforms, the fraction of buyers that find ...

Monitor Reputation and Transparency

American Economic Journal: Microeconomics, November 2023

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 present a framework that can be used to assess the equilibrium impact of regulation on endogenous innovation with heterogeneous firms. We implement this model using French firm-level panel data, where there is a sharp increase in the burden of labor re...

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...

Unpacking P-hacking and Publication Bias

By Abel Brodeur, Scott Carrell, David Figlio, and Lester Lusher

American Economic Review, November 2023

We use unique data from journal submissions to identify and unpack publication bias and p-hacking. We find initial submissions display significant bunching, suggesting the distribution among published statistics cannot be fully attributed to a publication...
