Modeling Heterogeneity in Trip-Distributions with Partial InformationKurt JornstenNorwegian School of Economics (NHH) - Department of Finance and Management Science Gisle KleppeStord Haugesund College Inge ThorsenStord Haugesund College Jan UboeNorwegian School of Economics (NHH) - Department of Finance and Management Science October 2007 NHH Dept. of Finance & Management Science Discussion Paper No. 2007/23 Abstract: In this paper we propose a modified gravity model that takes into account that a population generally consists of heterogeneous groups, and we suggest a new statistical test for heterogeneity. We apply our new model to two real world data sets, and it turns out that this new model fits the data surprisingly well. Not only is the effect of heterogeneity strongly significant, the model also provides far better fits than traditional trip-distribution models on these particular data sets.
