The Effect of Service Quality and Price on International Airline Competition
Published 2006-01-01A game theoretic model, integrated with passenger’s international choice behaviour, for the competition between international airlines is developed and used to identify the role of competing service quality. The empirical ...Open AccessWorking Paper -
Reducing Sign Violation for VTTS Distributions through Recognition of an Individual’s Attribute Processing Strategy
Published 2006-06-01A number of authors have recently argued that the selection of the distributional assumptions in mixed logit models, used in deriving distributions of valuation of travel time savings (VTTS) to capture taste heterogeneity, ...Open AccessWorking Paper -
Heteroscedastic Control for Random Coefficients and Error Components in Mixed Logit
Published 2006-03-01Developments in simulation methods, and the computational power that is now available, have enabled open-form discrete choice models such as mixed logit to be estimated with relative ease. The random parameter (RP) form ...Open AccessWorking Paper -
Approximation of Bayesian Efficiency in Experimental Choice Designs
Published 2006-06-01This paper compares different types of simulated draws over a range of number of draws in generating Bayesian efficient designs for stated choice studies. The paper examines how closely pseudo Monte Carlo, quasi Monte Carlo ...Open AccessWorking Paper -
Pricing in Dynamic Vehicle Routing Problems
Published 2006-04-01The principal focus of this paper is to study carrier pricing decisions for a new type of vehicle routing problems defined in a competitive and dynamic environment. This paper introduces the Vehicle Routing Problem in a ...Open AccessWorking Paper
