Climate scepticism remains an important barrier to public engagement with accurate climate information, because sceptics often actively avoid information that contains climate science facts. There still lacks a scalable, repeatable intervention to boost sceptics’ engagement with climate information...

A monopoly seller is privately and imperfectly informed about the buyer's value of the product. A designer can provide the seller with additional information, which the seller uses to price discriminate the buyer. We demonstrate the difficulty of screening the seller's information: When the buyer's...

Many platforms use Price Parity Clauses (PPCs) to prevent sellers charging lower prices elsewhere. In a setting where PPCs affect platforms’ data acquisition, we show that buyers and sellers may benefit from PPCs when the market is young.

This article analyzes more than 60,000 assessments of uncertainty made by national security officials from more than forty NATO allies and partners. The findings show that national security officials are overwhelmingly overconfident and that their judgments are especially prone to false positives....

We analyze the effect of media mergers in a model that stresses, on the one hand, the fact that media are two-sided platforms willing to attract advertisers and viewers and, on the other hand, that strong competitors have emerged to challenge traditional media on both sides. We show that a merger...

We construct Nash equilibria in feedback form for a class of two-person stochastic games of singular control with absorption, arising from a stylized model for corporate finance. More precisely, the paper focusses on a strategic dynamic game in which two financially-constrained firms operate in the...

Existing evidence suggests that individuals often misperceive the value of their wealth. We examine the existence, direction, and magnitude of these misperceptions through a laboratory experiment. Our findings indicate that variations in the leverage ratio (the ratio of liabilities to assets)...

This survey examines the economic literature on the incentives that shape both the use and the development of diagnostic tests, with a particular focus on companion (biomarker) tests central to precision medicine. Misdiagnosis, underdiagnosis, and overdiagnosis represent a substantial...

We analyze bubbles and crashes in a model in which some investors are partially sophisticated. While the expectations of such investors are endogenously determined in equilibrium, these are based on a coarse understanding of the market dynamics. We highlight how such investors may endogenously...
