While private monopolists are generally assumed to maximize profits, the goals of public enterprises are less well known. Using the example of Pennsylvania's state liquor retailing monopoly, we use information on store location choices, prices, wholesale costs, and sales to uncover the goals...

We examine the economies of density associated with the expansion of Amazon's distribution network from 2006 to 2018. We demonstrate that, in placing a fulfillment center in a new state, Amazon faces a trade-off between the revenue implications of exposing local customers to sales tax on their...

Government often chooses simple rules to regulate industry even when firms and consumers are heterogeneous. We evaluate the implications of this practice in the context of alcohol pricing where the regulator uses a single markup rule that does not vary across products. We estimate an equilibrium...

We explore the implications of ownership concentration for the recently-concluded incentive auction that re-purposed spectrum from broadcast TV to mobile broadband usage in the U.S. We document significant multi-license ownership of TV stations. We show that in the reverse auction, in which TV...

Recent technological changes may have altered the balance between technology and copyright law for digital products. While file-sharing has reduced revenue, other technological changes have reduced the costs of bringing creative works to market. As a result, we don't know whether the effective...

In the decade since Napster, file-sharing has undermined the protection that copyright affords recorded music, reducing recorded music sales. What matters for consumers, however, is not sellers' revenue but the surplus they derive from new music. The legal monopoly created by copyright is...

Economists have well-developed theories that challenge the wisdom of the common practice of uniform pricing. With digital music as its context, this paper explores the profit and welfare implications of various alternatives, including song-specific pricing, various forms of bundling, two-part...

Digitization has led to product proliferation, straining traditional institutions for product discovery; but digitization has also spawned crowd-based rating systems. We compare the relative impacts of professional critics and crowd-based Amazon star ratings on consumer welfare in book...

In the past few years, YouTube and other sites for sharing video files over the Internet have vaulted from obscurity to places of centrality in the media landscape. The files available at YouTube include a mix of user-generated video and clips from network television shows. Networks fear that...

Real interest rates rose to historically high levels in 1980 and remained high throughout the decade. Macroeconomists attribute this phenomenon to a combination of tight monetary policy, fiscal deficits, and variable inflation rates. This paper presents preliminary evidence for an additional...
