Abstract
Abstract Routine industrial analyses use internal market characteristics such as market shares to proxy for market power. However, recent studies argue that factors that are external to the market such as contact across multiple markets can be linked to tacit collusion. Using a structural demand and supply model for air travel, we quantify the variable profit effects of multimarket contact. We find that multimarket contact results in increases in variable profits ranging between $15,000 and $20,000 per contact in a quarter. Extrapolating this estimate across all contacts proves to be quite sizeable. These positive responses in profitability are especially stronger in less competitive markets. Our results, taken together, lend support to the mutual forbearance hypothesis.
期刊介绍：
The Review of Network Economics seeks to help policy makers, academics, and practitioners keep informed of new research and policy debate in network economics and related subjects that are relevant to the study of network industries. By publishing high quality research on topical issues relevant to network industries, it is hoped readers will be able to gain a deeper understanding of the economic issues involved and that this will improve the quality of decision making by private and public organisations, and debate among researchers. The articles can cover specific network industries, or may deal with general issues that have relevance to a number of different network industries, including topics in the economics of networks, regulation, competition law, or industrial organisation. Papers that provide insights into policy debates are especially welcome, as are up-to-date surveys, book reviews, and comments.
