We develop a duopoly model to analyze the impact of air transport and high-speed rail (HSR) competition on the environment and social welfare. We show that the introduction of HSR may have a net negative effect on the environment, since it may result in additional demand, i.e., there is a...

We study airport competition when some types of commercial services, such as car parking or car rental, may be offered at the time of air ticket purchase through the Internet, in order to stimulate aviation demand. We find that airports set a lower aviation charge than they would have levied in...
