The role of amenities in the flow of migrants has been debated for some years. This paper advances an original model of amenities that work through household production instead of directly through the utility function. Area characteristics (amenities) affect the household production function, causing certain kinds of human capital investments to be rewarded more than others. Area heterogeneity makes such investments specific to certain areas, in that some areas' characteristics will reward certain kinds of knowledge more than others. This specificity, along with an assumed period of exogenous location (before migration can be carried out) increases the opportunity costs of moving and diminishes migration flows between dissimilar locations. The new theoretical results differ from the results of the standard model. Empirical tests of the model's predictions against the predictions of the standard model using the NLSY79 Geocode Data Files are carried out. The results support the hypothesis that childhood investments affect migration flows in the way proposed by the model. Implications for regional development efforts carried out by municipalities are discussed.

Higher nominal wages in urban areas are well-documented phenomena which imply higher productivity of urban workers. Yankow and Wheeler show that these gains come through a variety of sources including static agglomeration economies and dynamic learning and matching efficiencies in cities. Yet, earlier articles offer little evidence of how the effects of learning and matching on urban wage differentials vary by city size. This article allows for the relative importance of these productivity advantages to differ according to the size of the city and finds significant differences between small, medium, and large cities. We find that learning efficiencies are most important in medium-sized cities, while a mix of learning and matching efficiencies are important in the largest and smallest cities.
