Competitive industries respond to positive demand-side and negative supply-side shocks in predictable ways. Prices will rise and, under some conditions, margins along with them. Margins may rise because of supply shocks, but they do so in competitive markets without collusion among producers....

A methodology is proposed to estimate structural models of product line competition. This methodology enables researchers to estimate demand systems accounting for the endogeneity of the mix of products available in each market, an issue which is typically ignored in the empirical literature. In...

Motivated by recent trends in apps and electronic media, I study the pricing decision of a durable-goods monopolist to derive conditions under which freemium pricing is optimal. Under freemium pricing, the firm charges a price of zero for the durable good but offers optional micro-transactions...

This paper develops a new approach that combines firm margins, market-level industry data and a static demand model to construct sets containing unbiased estimates of long-run price elasticities for storable good industries. It obviates the need to solve the consumer's value function and can be...

We quantify the welfare effects of zone pricing, or setting common prices across distinct markets, in retail oligopoly. Although monopolists can only increase profits by price discriminating, this need not be true when firms face competition. With novel data covering the retail home improvement...

A large body of research has established that exporters do not fully adjust their prices across countries in response to exchange rate movements, but instead allow their markups to vary. But while markups are difficult to observe directly, we show in this paper that inventory-sales ratios...

We present evidence from 260,000 online auctions of second-hand cars to identify the impact of public reserve prices on auction outcomes. To establish causality, we exploit multiple discontinuities in the relationship between reserve prices and vehicle characteristics to present RD estimates of...

We use more than 63,000 datapoints from a German used car market website to document systematic and substantial price drops at vintage (= year of first registration) thresholds and 10,000 km odometer marks. The latter finding replicates the findings in Lacetera et al. (2012), whereas the first...

In this paper, we study the effect of a firm's local channel exits on prices charged by incumbents remaining in the marketplace. Exits could result in higher prices due to tempered competition or lower prices due to reduced co-location or agglomeration benefits. The net effect of these two...
