This study considers the anti-competitive effect of fixed-fee pricing, such as the one seen in a recent antitrust case in Japan. We show that fixed-fee pricing has stronger exclusionary effect than the per-use pricing's exclusionary effect. However, the restriction on usage of fixed-fee pricing...

This paper constructs an entry and code-sharing alliances game to demonstrate that the alliance between the incumbent carriers may play a significant role of entry deterrence in a given airline network. We show that incumbents can use the alliances as a credible threat to deter the entry of the...

This paper studies the causal relationship between safety, profitability and the load factor for US airlines taking airline deregulation into account. The results indicate that there is some evidence that profitability and the growth of load factor cause fatalities/accidents. Bivariate causality...

This paper provides estimates of the elasticities of demand for the Brazilian basic plan of local fixed telephony using a cointegration model. We find a long-run price elasticity of –0.24, and an income elasticity of 0.18. These figures are line with other countries' estimates.

Coupled with the early wave of privatization in the 80s of state-owned telecom enterprises, the reform trend in the telecom market has shifted toward the market liberalization since the 90s, resulting in extended multilateral negotiations on the introduction of competition into basic...

We develop methods for calculating profit-maximizing and socially optimal rates of partial refunds on customers' no-shows and cancellations. We demonstrate how partial refunds can be used to screen consumers according to their different probabilities of cancellation and no-shows. Finally, we...

Kang, Weisman, and Zhang (2000) demonstrated that, under a tighter price cap, consumer welfare increases with the independence of demands. Conversely, the tighter price cap may negatively impact consumer welfare in situations involving interdependent demands. This paper identifies an overlooked...

I derive Ramsey optimal prices in one-way access of long-distance operators and enhanced service providers to local loops. As long-distance services and enhanced services become substitutes due to the advance of Internet telephony, the Ramsey principle requires higher access charges assessed on...
