Rivalry in the U.S. Airline Industry
No full textIn this paper, we use Market Share Instability (MSI) as a measure of the intensity of competition among airlines on a specific route. This measure is used to capture not only price competition but also non-price competition notably capacity competition. We test the effect of different variables (used in pricing studies) on MSI on a sample of 400 routes over the period 1987 to 1993. Most of the results found in pricing studies are confirmed using this measure of rivalry. For example the presence of a bankrupt carrier increases rivalry but extensive multimarket contact between rivals decreases competition. We also find that MSI was significantly lower in the early nineties when demand conditions were weak. A decline in the intensity of capacity competition could explain that result.

Demand Uncertainty and Airline Network Morphology with Strategic Interactions
No full textIn this paper, we examine how strategic interactions affect airline network. We develop a three stage duopoly game: at stage 1 airlines determines their network structure (linear versus hub-and-spoke). At stage 2 they decide on their capacities, and at stage 3 firms compete in quantities. The main feature of the model is that firms have to decide on network structure and capacities while facing demand uncertainty. We show that while hubbing is efficient, airlines may choose a linear network for strategic reasons. Furthermore, we show that this structure softens competition by preventing contagion of competition across markets.Airlines, Competition, Capacity constraints, Network, Uncertainty
Can Environmental Regulations be Good for Business? an Assessment of the Porter Hypothesis
No full textThe Porter hypothesis asserts polluting firms can benefit from environmental policies, arguing that well-designed environmental regulations stimulate innovation, which by increasing either productivity or product value, leads to private benefits. As a consequence, environmental regulations would benefit both society and regulated firms. This point of view has found a receptive audience among policy makers and the popular press but has been severely criticized by economists. In this paper, we present some of the arguments in this debate and review the empirical evidence available so far in the economic literature.Porter Hypothesis, Environmental Regulations, Competitiveness
