We build an oligopoly model of the market of scientific journals that allows us to relate the (in-)efficiency of this market to the exogenous distribution of article quality. Journal quality is endogenously determined by the submission choices of scientists. The efficiency of any stable...

We model strategic interaction on a market where two labeling organizations compete and firms in duopoly decide which labels to offer. The incumbent label maximizes its own profit, and is challenged by an industry standard which maximizes industry profit. Using a nested logit, the result of this...

We examine the role of price transparency in consumer preferences and demand. We assemble a detailed dataset on the driving school industry in Portugal to quantify how firms present the price of the course of instruction, and its individual components, to potential students. Our unique data...

We analyze the effect of consumer information on firm pricing in a model where consumers search for prices and matches with products. We consider two types of consumers. Uninformed consumers do not know in advance their match values with firms, whereas informed consumers do. Prices are lower the...

We study competitive interactions between Intel and Microsoft, two producers of complementary products. In a system of complements, like the PC, the value of the final product depends on how the different components work together. This, in turn, depends on the firms' investments in complementary...

Consumers are attracted by high quality search results. Search engines, though, essentially compete against themselves as consumers are induced to substitute away from advertisement links when their organic counterparts are of high quality. I characterize the effect of such revenue...

We consider an oligopolistic market where firms compete in price and quality and where consumers have heterogeneous information: some consumers know both the prices, and quality of the products offered, some know only the prices, and some know neither. We show that if there are sufficiently many...

This paper examines one of the most important marketing strategies by software producers on the Internet. That is whether to offer free samples and if so, whether to list the samples on shareware repositories. I show that firms with higher value products have a greater incentive to offer free...

This paper presents an examination of whether an antitrust authority should prohibit a quantity-setting duopolists' semi-collusive production cartel after noncooperative quality-improving R&D. Results show that values of the technological spillover and product differentiation parameters exist...

This paper endogeneizes the level of market coverage in a vertically differentiated market where firms decide first their qualities and next their prices. We extend the few endogeneization results to a more realistic setup, with quality dependent unit production costs. We show that, depending on...
