Price Discrimination in the Airline Market: The Effect of Market Concentration

Abstract: We test the hypothesis that price discrimination increases with competition in the airline market. Using a large cross section of tickets offered by several carriers on various routes, we approximate price discrimination with marginal implicit prices of ticket restrictions that carriers typically use to price discriminate: Saturday-night stayover re-quirements and advanced-purchase discounts. We find that the restrictions are associated with lower airfares, but that the discounts are smaller on routes with higher market concentration. The results suggest that price dispersion attributed to ticket restrictions increases as markets becomemore competitive.

Network Externalities and Technology Adoption: Lessons from Electronic Payments

Abstract: We seek to analyze the extent and sources of network externalities for the automated clearinghouse (ACH) electronic payments system using a quarterly panel data set on individual bank adoption and usage of ACH. We provide three methods to identify network externalities using this panel data. The first method identifies network externalities from the clustering of ACH adoption. The second method identifies them by examining whether banks in areas with higher market concentration or larger competitors are more likely to adopt ACH. The third method identifies them by examining whether the ACH adoption by small branches of large banks affects the adoption by local competitors. Using fixed effects and panel data these methods separately identify network externalities from technological advancement, peer-group effects, economies of scale and market power. We find evidence that the network externalities are moderately large.

Network Externalities and Technology Adoption: Lessons from Electronic Payments

Abstract: We analyze the extent of network externalities for the automated clearinghouse (ACH) electronic payments system using a panel dataset on bank adoption and usage of ACH. We develop three methods. The first examines the clustering of ACH adoption. The second examines the impact of market concentration and the size of competitors on ACH adoption. The third examines the impact of ACH adoption by small branches of large banks on local competitors. These methods separately identify network externalities from technological advancement, peer-group effects, economies of scale, and market power. We find evidence that the network externalities are moderately large.

Effect of Consumer Characteristics on the Use of Payment Instruments

Abstract: Predictions about a cashless and checkless society have been made for many years, but retail payments transactions made with electronic payment instruments still constitute only a small fraction of all payments made in the United States. This is the case despite differences in cost and despite marketing and educational campaigns conducted by the Federal Reserve and other institutions. One of the reasons the cost differences have little effect is that the differences in cost among payment instruments typically are not evident to consumers, who are charged the same amount regardless of how they pay. This article explores the possibility that consumer characteristics may affect the adoption of electronic payment instruments. Using data from the 1998 Survey of Consumer Finances, the author estimates the effect of several demographic characteristics on the probability of using electronic payments. She finds strong effects of demographic characteristics and of location on consumers’ choices. She suggests that the importance of location may indicate demand-related network effects, although further analysis of the supply side would be needed to test that hypothesis.

Model entry and exit in a differentiated-product industry: the personal computer market

Abstract: Entry and exit literature focuses almost exclusively on firm-level decisions, leaving out an important aspect of firm behavior: whether to introduce new models while the firm produces similar goods, and where to locate them in the existing product space, taking into account own models and the possibility of new entry. This paper analyzes model entry and exit decisions in the case of the personal computer market. Differences in new model spatial location between incumbents and entrants are found, while both model over- pricing and firm reputation are found to be significant in the probability of model's exit estimation.

The consolidation of the financial services industry: Causes, consequences, and implications for the future

Abstract: This article designs a framework for evaluating the causes, consequences, and future implications of financial services industry consolidation, reviews the extant research literature within the context of this framework (over 250 references), and suggests fruitful avenues for future research. The evidence is consistent with increases in market power from some types of consolidation; improvements in profit eAciency and diversification of risks, but little or no cost eAciency improvement on average; relatively little eAect on the availability of services to small customers; potential improvements in payments system eAciency; and potential costs on the financial system from increases in systemic risk or expansion of the financial safety net. ” 1999 Elsevier Science B.V.

The Economics of Two-Sided Markets

Abstract: At a local Best Buy, a child places a new Sony PlayStation 3 on the cashier’s counter while the parents dig out their Visa card. The gaming system and the payment card may appear to have little connection other than this purchase. However, these two items share an important characteristic that is generating a series of economic insights and has important implications for strategic decision making and economic policymaking. Both video game systems and payment cards are examples of two-sided markets. Broadly speaking, a two-sided market is one in which 1) two sets of agents interact through an intermediary or platform, and 2) the decisions of each set of agents affects the outcomes of the other set of agents, typically through an externality. In the case of a video game system, the intermediary is the console producer—Sony in the scenario above—while the two sets of agents are consumers and video game developers. Neither consumers nor game developers will be interested in the PlayStation if the other party is not. Similarly, a successful payment card requires both consumer usage and merchant acceptance, where both consumers and merchants value each others’ participation. Many more products fit into this paradigm, such as search engines, newspapers, and almost any advertisersupported media (examples in which consumers often negatively value, rather than positively value, the participation of the other side), as well as most software or title-based operating systems and consumer electronics. Malls which seek retailers and consumers, convention organizers which seek buyers and sellers, dating services which seek men and women, and The Journal of Economic Perspectives which seeks content and readership, all experience the economics of two-sided markets. The multi-sided nature of many Internet and high-technology markets, as well as

Social Networks and Technology Adoption in Northern Mozambique

Abstract: Despite their potentially strong impact on poverty, agricultural innovations are often adopted slowly. Using a unique household dataset on sunflower adoption in Mozambique, we analyse whether and how individual adoption decisions depend upon the choices of others in the same social networks. Since farmers anticipate that they will share information with others, we expect farmers to be more likely to adopt when they know many other adopters. Dynamic considerations, however, suggest that farmers who know many adopters might strategically delay adoption and to free-ride on the information gathered by others. We present empirical evidence which shows that the relationship between the probability of adoption and the number of known adopters is shaped as an inverse-U. In line with information sharing, the network effect is stronger for farmers who report discussing agriculture with others. The data contains information which is needed to ameliorate the identification issues that commonly arise in this context. In particular social networks are precisely identified, and in addition we can control for village heterogeneity and endogenous group information.
