Contrary to predictions that brick-and-mortar banking declines with increased financial innovations and technological adoptions, bank branch network between 2006 and 2018 has tripled and ATM networks have increased four-fold. In this paper, we examine whether network convenience matter for price...

We study firms' responses to minimum standards and other forms of regulatory intervention on both the probability of exit and the distribution of observable product quality, using firm level data for a nationally representative sample of markets. Our empirical work is motivated by the literature...

This paper examines how pharmaceutical firms have responded to changes in intellectual property rights and trade barriers that legalized "parallel imports" within the European Union. The threat of arbitrage by parallel traders reduces the ability of firms to price discriminate across countries....

We investigate mergers in markets where quality differences between products are central and firms may reposition their product lines by adding or removing products of different qualities following a merger. Such mergers are materially different from those studied in the existing literature....

Why are higher quality niches seen as intrinsically more profitable in business circles? Why do high quality products sometimes have a low real price, while it is unusual to see low quality products with high real prices? Can markets have quality differentiation as well as quality bunching? In...

After describing the essential features of the book market, a welfare analysis of the fixed book price agreement is given. Allowance is made for the opportunity cost of reading. Theoretically, the agreement pushes up book prices and depresses book sales. However, more titles will be published,...

This paper analyzes decisions of multi-product firms regarding product selection, innovation and advertising as choices of consumer valuation distributions. We show that a profit-maximizing monopolist chooses these distributions so as to maximize the dispersion of the valuation differences...

In the first essay, I analyze a symmetric duopolistic market where each firm's choice regarding certain quality attributes such as the environmental friendliness of its product is its own private information. I find that the extent of horizontal differentiation between firms plays a crucial role...

We investigate how price ceilings and floors affect outcomes in continuous time, double auction markets with discrete goods and multiple qualities. When price controls exist, the existence of competitive equilibria (the solution concept of classical market theory) is no longer guaranteed; hence, we...

We investigate how competition in product niches affects the ultimate timing of product release for experience goods using data on motion pictures in the United States. We identify product niches that movies occupy along three different product dimensions: common actor, common director, and...

It is widely accepted that firms compete by offering consumers lower prices, high-quality products, and a wide range of choices. With the increasing commercialization of personal, there is now a growing consensus that the level of privacy protection and deployment of Privacy Enhancing...

We investigate how competition in product niches affects the ultimate timing of product release for experience goods using data on motion pictures in the United States. We identify product niches that movies occupy along three different product dimensions: common actor, common director, and...

We uniquely examine the relationship between firm-sponsored training and product quality competition. Using an oligopolistic model of both price and quality competition, we show that an increase in the sensitivity of demand to product quality will strengthen firms’ incentives to train their...

Recent lawsuits and anecdotal evidence suggest that some platforms discriminate against certain users through non-price practices, discouraging their participation without directly increasing revenue. We show that a monopolist two-sided platform with a prejudice against certain users - modeled...

This analysis of global competitiveness of emerging market economies accounts for non-price aspects of competitiveness. Building on the methodology pioneered by Feenstra (1994) and Broda and Weinstein (2006), we construct an export price index that adjusts for changes in the set of competitors...

Do firms under relative payoff s maximizing (RPM) behavior always choose a strategy profile that results in tougher competition compared to firms under absolute payoffs maximizing (APM) behavior? In this paper we will address this issue through a simple model of symmetric oligopoly where firms...

This paper considers horizontal merging decision under price and quality competition and examines whether two competing firms should merge and which merging strategy (i.e., centralized or decentralized merger) is optimal. Although horizontal mergers are prevalent in practice and have been...

New empirical evidence shows substantial heterogeneity in the altruism of healthcare providers. Spurred by this evidence, we build a spatial quality competition model with altruism heterogeneity. We find that more altruistic healthcare providers supply relatively higher quality levels and...

Do firms under relative payoffs maximizing (RPM) behavior always choose a strategy profile that results in tougher competition compared to firms under absolute payoffs maximizing (APM) behavior? In this paper we will address this issue through a simple model of symmetric oligopoly where firms...

This paper examines non-price competition among colleges to attract highly qualified students, exploiting the South Korean setting where the national government sets rules governing applications. We identify some basic facts about the behavior of colleges before and after a 1994 policy change...
