This paper examines how changes in product market concentration, specifically firm exit, affect prices. I develop a model where firms have variable markups to show that the remaining firms increase their markups and prices after their competitors’ exit. The model predictions are tested using...

This paper examines the welfare implication of banning price discrimination in the intermediate goods market in which a monopolistic supplier contracts with asymmetric downstream retailers. We demonstrate that the supplier has a strong incentive to manipulate interdependent demand structure...

This paper analyzes the behavior of prices and finished-goods inventories in a model of monopolistic competition, where the motivation for holding inventories is the prospect of lost sales. An eventual goal of the present investigation is the development of an empirical framework, based on a...

This paper provides some new empirical features on price setting behaviour for French producers using micro data underlying the producer and business-services price indices over the period 1994-2005. Some crucial methodological issues on the collection of producer prices are raised. Then, the...

We investigate the effect of COVID-19 epidemic and the subsequent stay-at-home order on market efficiency in China’s online markets, by comparing the changes in price dispersion around the date of the lockdown with the corresponding changes in the same period in the lunar year of 2019. We find...
