Inter-basin Water Transfers and the Size of Regions: An Economic Geography Example
(Revise and Resubmit)
A two-region, spatial general equilibrium model is developed to explore the implications of interregional water transfers on household migration and the intraregional distribution of land between urban and agricultural use when there are agglomeration economies in urban production. A particular example is considered where an arid region lacks water resources but has a comparative advantage in both agricultural productivity and household amenities. The conditions for the stability of both the dispersed and concentrated equilibria are found. Numerical simulations provide a graphical example of the set of stable equilibria in the parameter space. Finally, the model is calibrated using data on household consumption and agricultural production patterns in the US.
Cultural Workers and the Character of Cities
(Received Springer Award for Best Paper by Early Career Scholar at 2017 Western Regional Science Association Conference)
This paper develops a conceptual two region general equilibrium model with heterogeneous agents in order to explore the tradeoffs between the market size in aggregate demand and market crowding effects in housing costs that cultural producers face in cities that foster industries with agglomeration economies. When all types of workers supply labor inelastically, we find that concentration is always a stable equilibrium and define the conditions for segregated and integrated equilibrium to be stable. An extension is considered where cultural producers can divide their time between working in the arts or in a constant returns production sector.
The development of interregional water transportation over the past fifty years, which has been used to supply arid regions with water for urban and agricultural use, poses an interesting question with the current global trend towards urbanization. If the lack of a sufficient local water supply is no longer an impediment for urban growth or agricultural production, how will water need to be allocated over space when there is heterogeneity in agricultural land and agglomeration economies in cities? This paper develops a two region trade model with heterogeneous agricultural productivity and natural amenities, and interregional mobility of water resources in order to explore the long run spatial allotment of land and water for urban and agricultural use. The effects of key parameters are explored analytically for a special case. In addition, the model is solved numerically to allow comparisons among various policy scenarios.
The Monocentric City with Heterogeneous Land
The purpose of this paper is to integrate heterogeneous land quality into the monocentric city model. Three distinct models are employed. The first adds variable land quality to the developers cost function in a static, land use model, in which all development is perfectly malleable. Structural density is found to be increasing with land quality. A second, dynamic model analyzes how land quality affects development timing and structural density decisions. Sufficient conditions are found for buildings of higher structural density to be constructed earlier and for leapfrog development to occur. These models allow for greater flexibility in the structural density, development timing and bid-rent functions at a finer spatial scale.
