We study insurers' use of prescription drug formularies to screen consumers in the ACA Health Insurance Exchanges. We begin by showing that Exchange risk adjustment and reinsurance succeed in neutralizing selection incentives for most, but not all, consumer types. A minority of consumers,...

Amenities such as good food, attentive staff, and pleasant surroundings may play an important role in hospital demand. We use a marketing survey to measure amenities at hospitals in greater Los Angeles and analyze the choice behavior of Medicare pneumonia patients in this market. We find that...

This paper investigates how increases in concentration can be interrupted or reversed by changes in how firms compete on quality. We examine the U.S. hotel industry during the past half century. We document that starting in the early 1980s, quality competition came more in the form of costs that...

Hirschman's Exit, Voice, and Loyalty highlights the role of “voice” in disciplining firms for low quality. We develop a formal model of voice as a relational contact between firms and consumers and show that voice is more likely to emerge in concentrated markets. We test this model using...

Agglomeration is a location pattern frequently observed in service industries such as hotels. This paper empirically examines if agglomeration facilitates tacit collusion in the lodging industry using a quarterly dataset of hotels that operated in rural areas across Texas between 2003 and 2005....

Using a sample of highly (over-)leveraged Austrian ski hotels undergoing debt restructurings, we show that reducing a debt overhang leads to a significant improvement in operating performance (return on assets, net profit margin). In particular, a reduction in leverage leads to a decrease in...

Online reviews could, in principle, greatly improve consumers' ability to evaluate products. However, the authenticity of online user reviews remains a concern; firms have an incentive to manufacture positive reviews for their own products and negative reviews for their rivals. In this paper, we...

California's per-capita electricity consumption is 50 percent lower than national per-capita consumption. Mild climate, deindustrialization, and its demographics explain part of this differential. California energy efficiency policy is often claimed to be another key factor. A challenge in...

We show that oil production from existing wells in Texas does not respond to price incentives. Drilling activity and costs, however, do respond strongly to prices. To explain these facts, we reformulate Hotelling's (1931) classic model of exhaustible resource extraction as a drilling problem:...

We use field-level cost estimates of all oil and natural gas fields to highlight dynamic aspects of a global carbon tax. Some of the initial reduction in consumption will be offset through higher consumption later on. Only high-cost reserves will be priced out of the market, e.g., at 200 dollars...
