| Tiivistelmä: | This paper introduces a zonal model of recreation that captures som of the underlying heterogeneity of individual visitors by incorporating distributional information on per-capita income from census sources into the aggregate demand function. This adjustment eliminates the unrealistic constraint of parameters. The corrected aggregate specification reinstates the applicability of generalized maximum-likelihood methods, and inccreases model effiiciency. |
