We investigate a multi-market Cournot model with strategic process R&D investments wherein a multi-market monopolist meets entrants that enter one of the markets. We find that entry can enhance the total R&D expenditure of the incumbent firm. That is, entry can stimulate R&D effort. Moreover,...

This paper provides the first analysis of the trade-off between convenient flight connections and airport congestion. A continuous spatial model illustrates this trade-off in a framework where a small gap between flight operating times raises congestion while also shortening a connecting...

This study investigates whether airports should be prohibited from charging differential charges to airlines, as the 1944 Chicago Convention and the EU directive intend. We consider an international network in which two countries’ airports are interlinked and served by each country’s...

This study investigates airport pricing and capacity investment when passengers face schedule and congestion delays. Two countries' airports are served by each country's home carrier. Airports choose their charges on a per-flight and/or per-passenger basis. Carriers choose both quantities and...

This paper investigates airport privatization by two countries. Each country has a (gateway) hub airport a local airport. In each country, a hub carrier operates hub-local and international hub-hub flights, and a regional carrier also operates hub-local flights and forms and alliance with the...

This paper investigates should an airline offer vertically differentiated services, which are substitutes of its own services. The airline operates a certain number of direct flights to offer various types of services including nonstop, one-stop, or multiple-stop services. Homogenous passengers...

Using a general-equilibrium model that includes consumers, airlines, and an airport with both aeronautical service and non-aeronautical service, this paper investigates the airport's decisions on its aeronautical charge and capacity, as well as the size of its non-aeronautical service. In...

This study investigates airport congestion pricing and capacity investment with cost recovery consideration. Two countries’ airports are interlinked and served by each country’s home carrier. Our global welfare maximization shows that when per-passenger subsidies are not feasible under...
