We study how firms differ from their competitors using new time-varying measures of product differentiation based on text-based analysis of product descriptions from 50,673 firm 10-K statements filed yearly with the Securities and Exchange Commission. This year-by-year set of product...

Is skill dispersion a source of comparative advantage? While it is established that a country's aggregate endowment of human capital is an important determinant of comparative advantage, this paper investigates whether the distribution of skills in the labor force can play a role in the...

Using an incentivized measure of test for competition, this paper investigates whether this taste explains subsequent gender differences in earnings and industry choice in a sample of high-ability MBA graduates. We find that "competitive" individuals earn 9% more than their less competitive...

This paper investigates the efficiency of the Japanese distribution system, measured by the distribution margin. Most of the discussions on the Japanese distribution system have so far relied on institutional descriptions and anecdotal evidence, failing to substantiate the case. The present...

Consumers often benefit from increased competition in differentiated product settings. In this paper we consider consumer benefits from increased competition in a differentiated product setting: the spread of non-traditional retail outlets. In this paper we estimate consumer benefits from...

We analyze a number of unstudied aspects of retail electricity competition. We first explore the implications of load profiling of consumers whose traditional meters do not allow for measurement of their real time consumption, when consumers are homogeneous up to a scaling factor. In general,...

The standard economic model of efficient competitive markets relies on the ability of sellers to charge prices that vary as their costs change. Yet, there is no restructured electricity market in which most retail customers can be charged realtime prices (RTP), prices that can change as...

Prior research shows grocery stores reduce prices to compete with Walmart Supercenters. This study finds evidence that the competitive effects of two other big box retailers - Costco and Walmart-owned Sam's Club - are quite different. Using city-level panel grocery price data matched with a...

The potential benefits of demand side interventions may leak into the profits of suppliers whenever there is market power. In those situations, governments could attempt to regulate the market or to increase competition. We provide the first experimental evidence on the effect of increased...

Regulations aimed at curbing the entry of large retail stores have been introduced in many countries to protect independent retailers. Analyzing a planning reform launched in the United Kingdom in the 1990s, I show that independent retailers were actually harmed by the creation of entry barriers...
