This paper analyses the cost of access travel time variability for air travelers. Reliable access to airports is important since it is likely that the cost of missing a flight is high. First, the determinants of the preferred arrival times at airports are analyzed, including trip purpose, type of airport, flight characteristics, travel experience, type of check-in, need to check-in luggage. Sec...

We hypothesize that owing to limited investor attention and skepticism of complexity, innovative diversity (ID) of a firm's patent portfolio will be undervalued. ID strongly predicts stock returns after controlling for firm characteristics and risk. High ID portfolios provide Carhart alphas of 56-81 basis points per month and stronger and less volatile operating performance. The Diversified Min...

This article explores the development of previous models to determine hubs in a competitive environment. In this paper, by comparing parameters of the ticket price, travel time and the service quality of hub airports, airline hubs are divided into six categories. The degree of importance of travel time and travel cost are determined by a multivariate Lagrange interpolation method, which can pla...
