Measuring Competition in the U.S. Airline Industry Using the Rosse-Panzar Test and Cross-Sectional Regression Analyses AgEcon
Fischer, Thorsten; Kamerschen, David R..
We employ the Rosse-Panzar test to assess market performance in selected airport-pairs originating from Atlanta. The Rosse-Panzar test stands in the tradition of the New Empirical Industrial Organization. It is based on the comparative statics of a reduced form revenue equation. Therefore, it is less powerful than structural models, but it offers the advantage of less stringent data requirements and reduces the risk of model misspecifications. The test statistic allows us in most airport-pairs to reject both conducts consistent with the Bertrand outcome, which is equivalent to perfect competition, and the collusive outcome, which is equivalent to joint profit-maximization. Rather, the test statistic suggests that behavior is consistent with a range of...

Testing for Oligopoly Power in the Kenyan Seed Maize Processing Industry AgEcon
Nzuma, Jonathan M..
In the recent past, the concentration of seed maize processing and marketing in Kenya has raised serious public concerns. The inability of this industry to ensure affordable prices of certified seed maize for the farming community has led policy makers to question its market behaviour. In spite of these concerns, the performance of agricultural markets in Kenya has received little attention. This study evaluates the market conduct of the industry using the New Empirical Institutional Organization framework and tests the hypothesis of price taking behaviour. A system of five equations was used to estimate conjectural variations elasticity while a Lerner index was constructed to measure market power using data from Kenya's Central Bureau of Statistics. The...
