Price Dispersion and Stockpiling by Consumers

Review of Economic Studies 1983 50(3), 443
This paper presents a model of equilibrium price dispersion in which buyers do not search. However they are able to store the non-durable commodity for future use. Such behaviour implies sellers' demand curves are endogenously generated by the observed price distribution. Equilibrium is shown to exist. Although more than one price may be charged in equilibrium, the monopoly price will occur with positive probability. Comparative static results are derived with a linear version of the model, some of which are "perverse".

Inequality in the Local Public Sector

Journal of Political Economy 1982 90(1), 128-145
Effects on renters' welfare of changes in local government spending are examined in a multijurisdiction model. In equilibrium each income class chooses the jurisdiction whose combination of local public output and housing price maximizes utility. Comparative-static analysis of this equilibrium is used to show how inequality in local public expenditure benefits low-income residents. If low-income residents are observed to choose jurisdictions with low levels of per capita public expenditure, then they may be worse off by outside aid which increases local public expenditure in their jurisdictions. The advantages of inequality in the local public sector also exist when a program of tax base equalization is introduced.
