| This study analyses the stochastic behavior of price-cost margins (PCMs) in the U.S. meat industry. It, first, develops and estimates a vertical relationship economic model to derive PCMs in the U.S. meat industry (Beef, Pork, and Poultry). Second it analyzes the behavior of PCMs by decomposing them into their seasonal, cyclical, and trend components using the state-space and the Kalman filtering methods. Price-cost margins in the U.S. meat industry are governed by two common trends and two common cycles. The study also found cyclical variability of PCMs is the highest with chicken, secular variability of PCMs is the highest with pork, while seasonal variability of PCMs is the highest with beef. |

| 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... |
