Recent literature notes that when quality is produced with fixed costs, a high quality firm can undercut its rival's prices and may find it profitable to invest more in quality as market size grows large. As a result, a market can remain concentrated even as it grows large. When quality is...

This paper investigates the effect of (potential) market size on entry of new drugs and pharmaceutical innovation. Focusing on exogenous changes driven by U.S. demographic trends, we find that a 1 percent increase in the potential market size for a drug category leads to a 4 to 6 percent...

This paper explores the risk structure of interest rates. More specifically, we ask whether yields on industrial and commercial bonds indicate that market participants base their evaluations of a bond issue's default risk on agency ratings or on publically available financial statistics. Using a...

We analyze the information content of the digital footprint - information that people leave online simply by accessing or registering on a website - for predicting consumer default. Using more than 250,000 observations, we show that even simple, easily accessible variables from the digital...

For decades credit rating agencies were viewed as trusted arbiters of creditworthiness and their ratings as important tools for managing risk. The common narrative is that the value of ratings was compromised by the evolution of the industry to a form where issuers pay for ratings. In this paper...

Under the Affordable Care Act, individual states have discretion in how they define coverage regions, within which insurers must charge the same premium to buyers of the same age, family structure, and smoking status. We exploit variation in these definitions to investigate whether the size of...

We examine the forecasting power of international portfolio flows for local equity markets and attempt to attribute it to either better information about fundamentals on the part of international investors, or to price pressure. Price pressure is a potential explanation because flows have...

Using a detailed dataset of hospitals' purchase orders, we find that information on purchasing by peer hospitals leads to reductions in the prices hospitals negotiate for supplies. Identification is based on staggered access to information across hospitals over time. Within coronary stents,...

This paper explores the economic role credit rating agencies play in the corporate bond market. We consider three existing theories about multiple ratings: information production, rating shopping and regulatory certification. Using differences in rating composition, default prediction and credit...

We use yield spreads to construct ex-ante returns on corporate securities, and then use the ex-ante returns in asset pricing assets. Differently from the standard approach, our tests do not use ex-post average returns as a proxy for expected returns. We find that the market beta plays a much...
