Optimal Collateralized Contracts

We examine the role of collateral in a dynamic model of optimal credit contracts in which a borrower values both housing and nonhousing consumption. The borrower's private information about his income is the only friction. An optimal contract is collatera...

Information Transmission under the Shadow of the Future: An Experiment

By Alistair J. Wilson and Emanuel Vespa

American Economic Journal: Microeconomics, November 2020

We experimentally examine how information transmission functions in an ongoing relationship. Where the one-shot cheap-talk literature documents substantial overcommunication and preferences for honesty, the outcomes in our repeated setting are more consis...

Testable Implications of Models of Intertemporal Choice: Exponential Discounting and Its Generalizations

By Federico Echenique, Taisuke Imai, and Kota Saito

American Economic Journal: Microeconomics, November 2020

The Importance of Commitment Power in Games with Imperfect Evidence

By Francisco Silva

American Economic Journal: Microeconomics, November 2020

The literature initiated by Green and Laffont (1986) studies principal-agent models with hard evidence. Evidence is modeled by assuming that the message set of the agent is type dependent. In this setup, Glazer and Rubinstein (2004, 2006) and Sher (2011) ...

Hybrid All-Pay and Winner-Pay Contests

By Johan N. M. Lagerlöf

American Economic Journal: Microeconomics, November 2020

In many contests in economic and political life, both all-pay and winner-pay expenditures matter for winning. This paper studies such hybrid contests under symmetry and asymmetry. The symmetric model assumes very little structure but yields a simple close...

Informational Cycles in Search Markets

By Eeva Mauring

American Economic Journal: Microeconomics, November 2020

I show that market participants' equilibrium beliefs can create fluctuations in the volume of trading, even in a stationary environment. I study a sequential search model where buyers face an unknown distribution of offers. Each buyer learns about the dis...

From Extreme to Mainstream: The Erosion of Social Norms

By Leonardo Bursztyn, Georgy Egorov, and Stefano Fiorin

American Economic Review, November 2020

Social norms, usually persistent, can change quickly when new public information arrives, such as a surprising election outcome. People may become more inclined to express views or take actions previously perceived as stigmatized and may judge others less...

How Well Targeted Are Soda Taxes?

By Pierre Dubois, Rachel Griffith, and Martin O'Connell

American Economic Review, November 2020

Soda taxes aim to reduce excessive sugar consumption. We assess who is most impacted by soda taxes. We estimate demand using micro longitudinal data covering on-the-go purchases, and exploit the panel dimension to estimate individual-specific preferences....

Seasonal Liquidity, Rural Labor Markets, and Agricultural Production

American Economic Review, November 2020

Rural economies in many developing countries are characterized by a lean season in the months preceding harvest, when farmers have depleted their cash and grain savings from the previous year. To identify the impacts of liquidity during the lean season, w...

Does When You Die Depend on Where You Live? Evidence from Hurricane Katrina

By Tatyana Deryugina and David Molitor

American Economic Review, November 2020

We follow Medicare cohorts to estimate Hurricane Katrina's long-run mortality effects on victims initially living in New Orleans. Including the initial shock, the hurricane improved eight-year survival by 2.07 percentage points. Migration to lower-mortali...

Gambling over Public Opinion

By Deepal Basak and Joyee Deb

American Economic Review, November 2020

We consider bargaining environments in which public opinion provides leverage by making compromises costly. Two parties make initial demands, before knowing the public opinion. If deadlocked, they can bargain again after public opinion forms, but suffer r...
