1.Is There a Kuznets Curve for Intra-City Earnings Inequality? (Job Market Paper)
Abstract: Many papers have found a positive relation between income inequality and city size in the US and other countries. This literature has assumed that the relation is linear. Tests performed here find that it is concave, resembling the classic Kuznets curve. A theoretical model based on the Income Elasticity Hypothesis (IEH), explains that inequality is a concave function of housing prices that tend to increase with city size. Further tests confirm the concavity of the relation between Gini and housing costs that is predicted by the IEH. Although for most cities, inequality still rises with housing costs, if housing costs continue to grow in large cities, inequality should eventually fall, resembling the Kuznets Curve at the country level.
2.Declining Internal Migration: Testing Migration Models by Decomposing Migration Types
Abstract:Persistent declines in the rates of interstate and intercity migration have been noted in many recent studies. Research has indicated that this trend does not appear to be due to changes in population composition. This paper retests the population composition hypothesis along with two other theoretical possibilities, falling returns to migration, and improved search and matching technology. In the end a range of empirical tests establish results that are partially consistent with the hypothesis of falling returns to migration. The fact that return migration rates have risen while gross, initial and subsequent rates have fallen, reported for the first time in this study, is particularly difficult to reconcile with some existing theories. The results in this paper suggest more study focusing on alternative explanations for the declining rate of internal migration.
3.The Effect of On-line Shopping on Multi-Product Retail Market
Abstract: There is substantial evidence that the rise of on-line shopping is having substantial implications for bricks and mortar retailing. In this paper, a spatial competition model is built with a large multiproduct shopping center and numerous local single-product stores in the market. The model is capable of generating a spatial equilibrium that includes multi-product retail centers and individual retailers. Then on-line shopping technology is introduced. The bricks and mortar structure of retailing changes substantially. Whereas initially multi-product centers had an incentive to use profits from durable goods to subsidize non-durables to attract shoppers from individual retailers, on-line shopping completely reverses this pattern and changes the emphasis of the multi-product retail center. The spacing of both multi-product centers and independent retailers also changes as a result of on-line entry. This is the first paper of its type to generate theoretical implications of the effects of on-line shopping.
