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 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...

It is standard in experimental economics to use decontextualized designs where payoff structures are presented using neutral language. Here we show that cooperation in such a neutrally framed Prisoner’s Dilemma is equivalent to a PD framed as contributing to a cooperative endeavour....

We show that subjects who set their minimum acceptable offer to zero in an ultimatum game are the most generous players in a dictator game. This finding challenges the interpretation of the acceptance of low offers as payoff-maximizing behavior.

Recent research has documented a U-shaped industrial concentration curve over an economy’s development path. How far can neoclassical trade theory take us in explaining this pattern? We estimate the production side of the Heckscher–Ohlin model using industry data on 44 developed and...

We employ industry data to examine price stickiness of durables versus non-durables to evaluate Barsky et al. (2007) proposal that stickiness of durables’ prices influences aggregate dynamics. Policy impacts from impulse responses accord with sticky-price frameworks even though...

We consider a dual labor market with a frictional formal sector and a competitive informal sector. We show that the size of the informal sector is generally too large compared to the optimal allocation of the workers. It follows that our results give a rationale to informality-reducing policies.

While most of the literature explaining the change in consumption composition has focused on the role of relative prices and non-homothetic preferences, this paper examines the importance of preference shifts. I introduce dynamics in preferences and find that they play a relevant role and that...

This study constructs a general oligopolistic equilibrium model in which Smith’s (1776) famous theory of the division of labor under vertical specialization is embedded. We demonstrate that a pro-competitive government policy weakens the division of labor and hence reduces firm productivity,...

In an experiment, a group of strangers was randomly divided in pairs to play a prisoners’ dilemma; this process was indefinitely repeated. Cooperation did not increase when subjects could send public messages amounting to binding promises of future play.
