The U.S. Coal Industry: Market Structure & Implications, Sara Elizabeth Guffey

Graduate Theses, Dissertations, and Problem Reports

The U.S. coal mining industry was once a booming industry which created and defined communities, particularly in Appalachia. The industry has, however, transformed significantly in the last couple of decades with the passage of environmental policies, with competition from the Shale Revolution, from changes in company ownership, and from mine safety regulation. Overall, the coal industry during this time has experienced a massive decline in production and employment. This dissertation is composed of three papers that investigate these mechanisms and their role in understanding market structure, coal transactions and prices, and mine safety outcomes. Motivated by the shutdowns of U.S. …

What’S In Your Wallet (And What Should The Law Do About It?), Natasha Sarin

All Faculty Scholarship

In traditional markets, firms can charge prices that are significantly elevated relative to their costs only if there is a market failure. However, this is not true in a two-sided market (like Amazon, Uber, and Mastercard), where firms often subsidize one side of the market and generate revenue from the other. This means consideration of one side of the market in isolation is problematic. The Court embraced this view in Ohio v. American Express, requiring that anticompetitive harm on one side of a two-sided market be weighed against benefits on the other side.

Legal scholars denounce this decision, which, …

Drilling In The Drought: The Industrial Organization Of Groundwater, Ujjayant N. Chakravorty, E. Somanathan

Ujjayant Chakravorty

China and India together produce about half the world's rice and a third of the world's wheat, but production in both countries is heavily dependent on depleting groundwater resources. A large proportion of farmers buy and sell groundwater - the trading facilitated by small farm sizes and fragments land holdings. The economics of groundwater, when farm sizes are small, is little understood. This paper develops a simple, spatial model of the industrial organization of groundwater markets appropriate for smallholder agriculture. We show that if water is abundant, then equilibrium with free entry results in Bertrand competition, with water sellers charging …

Competition For Innovation, Herbert J. Hovenkamp

All Faculty Scholarship

Both antitrust and IP law are limited and imperfect instruments for regulating innovation. The problems include high information costs and lack of sufficient knowledge, special interest capture, and the jury trial system, to name a few. More fundamentally, antitrust law and intellectual property law have looked at markets in very different ways. Further, over the last three decades antitrust law has undergone a reformation process that has made it extremely self conscious about its goals. While the need for such reform is at least as apparent in patent and copyright law, very little true reform has actually occurred.

Antitrust has …

Multiple-Product Firms And Product Switching, Andrew B. Bernard, Stephen J. Redding, Peter K. Schott

Dartmouth Scholarship

This paper examines the frequency, pervasiveness, and determinants of product switching by US manufacturing firms. We find that one-half of firms alter their mix of five-digit SIC products every five years, that product switching is correlated with both firm- and firm-product attributes, and that product adding and dropping induce large changes in firm scope. The behavior we observe is consistent with a natural generalization of existing theories of industry dynamics that incorporates endogenous product selection within firms. Our findings suggest that product switching contributes to a reallocation of resources within firms toward their most efficient use. (JEL L11, L21, L25, …

Clean Air Regulation And Heterogeneity In Us Gasoline Prices, Ujjayant N. Chakravorty, Celine Nauges, Alban Thomas

Ujjayant Chakravorty

In order to improve public health in areas with air quality problems, the US Clean Air Act imposes a variety of federal regulations on gasoline, which have led to a proliferation of fuel blends known as ‘‘boutique fuels.’’ More than 45 fuel blends are sold nationwide. We examine the effects of this program on wholesale gasoline prices. The methodological innovation in this study is the use of a regulatory distance measure as a proxy for measuring market power that arises from product differentiation. We find that Clean Air regulation increases gasoline prices by increasing the cost of refining, but more …
