In the standard market-microstructure model of Glosten and Milgrom (1985), public information can have negative social value. Equivalently, an increase in informational asymmetry can raise the total surplus from trade.

We analyze a strategic trading model where an overconfident insider is required to publicly disclose his trades after the fact. We find the more confident insider is more concerned about the effect the initial trading has on the future.

A restricted-perceptions equilibrium exists in which risk-averse agents believe stock prices follow a random walk with a conditional variance that is self-fulfilling. When agents estimate risk, bubbles and crashes arise. These effects are stronger when agents allow for ARCH in excess returns.

We use micro level retail price data from convenience stores to study the link between 0-ending price points and price rigidity during a period of a runaway inflation, when the annual inflation rate was in the range of 60%–430%. Surprisingly, we find that more round prices are less likely to...

Presenting a novel model of local shopping, the benefit of monopoly provision due to market size effects is explored. Prices are lower, variety and aggregate consumer surplus higher, than local shopping but many shoppers’ utility falls. Policymakers should take care.

This paper investigates hypotheses related to efficiency and price uniformity in online competing auctions based on two theoretical predictions from Peters and Severinov [Peters, M., Severinov, S., 2006. Internet auctions with many traders. Journal of Economic Theory 130, 220–245]. The...

The possibility of forward trading has been shown to restore social efficiency in Cournot oligopolies if marginal costs are constant. The paper analyzes the more general case that marginal costs are non-decreasing. I show that increasing marginal costs diminish the “strategic...

Prices that end with 9, also known as psychological price points, are common, comprising about 70% of the retail prices. They are also more rigid than other prices. We take advantage of a natural experiment to document an emergence of a new price ending that has the same effects as 9-endings. In...

We report results from a decentralized bargaining market experiment conducted with farmers and students. Our results indicate that despite its bad reputation, performance is highly efficient (although not as efficient as the competitive equilibrium prediction). Farmers and students perform...

The paper develops a housing deep-habit model to explore linkages between macroeconomic decisions and asset pricing of nondurable and housing goods. Owing to heterogeneous characteristics of housing assets, the model sheds insights into the counter-cyclical property of housing markups.
