Policy attention to the security industry increased substantially after the terrorist attacks in the U.S. on September 11th, 2001. With an increased demand for security, the global security market grew a tenfold to around €100 billion in 2011. Many studies expect that growth of the worldwide...

We examine the impacts of the EU-US Open Skies agreement on the environment, in particular looking at the effect of the agreement on emissions from the aviation sector. We use the Hamburg Tourism Model, a model of domestic and international tourist numbers and flows, to estimate these impacts....

This paper analyzes the effects of market structure on price dispersion in the airline industry, using panel data from 1993 through 2006. The results found in this paper contrast with those of Borenstein and Rose (1994), who found that price dispersion increases with competition. We find that...

This paper assesses the impact of the September 11th terrorist attacks and its after-effects on U.S. airline demand. Using monthly time-series data from 1986-2003, we find that September 11th resulted in both a negative transitory shock of over 30% and an ongoing negative demand shock amounting...

This paper documents the growth of low cost carriers (LCCs) in the U.S. airline industry since 1990. By estimating simple probit models, we quantify the market characteristics which have influenced nonstop LCC entry in 351 city-pair markets over the past decade. We confirm that pre-entry market...

This paper analyzes the responses of incumbent hub-and-spoke carriers to low cost carrier (LCC) entry on routes served to and from their hubs over the past decade. Our analysis finds that the typical price and capacity response by incumbent hub-and-spoke carriers to LCC entry has been fairly...

This paper presents an analysis of the structural changes the US-airline industry experienced since deregulation of that industry in 1978. The impact of concentration on competition and prices is evaluated for different segments of the market. Finally, conclusions for the ongoing process of...

We study the competitive effects of five liquidations and six mergers in the domestic U.S. airline industry between 1995 and 2010. Applying fixed effects regression models we find that route exits due to liquidation lead to substantially larger price increases than mergerrelated exits. Within...
