In this paper we determine the effect of transport cost on commuting flows, on the basis of an analysis of home …-to-work journeys between municipalities in Denmark. Special attention is given to a proper estimation method and the form of the … of commuting reaches a value of –4 for distances around 24 km, while it is close to 0 for both very short and very long …

We employ a semi-parametric estimation approach to analyse observed and unobserved heterogeneity in the value of … savings in travel time and schedule delay. Our econometric approach allows for the estimation of unobserved and observed …, we illustrate the estimation approach and find that there is substantial heterogeneity in the value of savings in travel …

Greece, given the significant impact of tourism on the country's economy. For the empirical analysis the authors estimated an … relatively high and the considered variables are statistically significant. Tourism flows to Greece are negatively affected by … the bilateral distance and climate similarity between Greece and the origin countries; furthermore, the response variable …

Tobit estimation, truncated regression, probit regression and substitutions for zero flows have been suggested. We argue …
