When Worlds Collide : Different Comparative Static Predictions of Continuous and Discrete Agent Models with Land
Berliant, Marcus - 2019
This paper presents a difference in the comparative statics of general equilibrium models with land when there are finitely many agents, and when there is a continuum of agents. Restricting attention to quasi-linear and Cobb-Douglas utility, it is shown that with finitely many agents, an...

Can Information Asymmetry Cause Agglomeration?
Berliant, Marcus - 2017
the agglomeration of agents in size or mass. We investigate agglomeration in sorting or by type of worker, that implies … agglomeration in size when worker populations differ by type. This kind of agglomeration can be driven by asymmetric information in …

The Indeterminacy of Equilibrium City Formation Under Monopolistic Competition and Increasing Returns
Berliant, Marcus; Kung, Fan-chin - 2018
We study the indeterminacy of equilibrium in the Fujita-Krugman model of city formation under monopolistic competition and increasing returns. Both the number and the locations of cities are endogenously determined. Assuming smooth transportation costs, we examine equilibria in city-economies...

Equilibrium and the Core in Alonso's Discrete Population Model of Land Use
Berliant, Marcus; ten Raa, Thijs - 2013
Conventional wisdom tells us that with no market failure and local non-satiation of preferences, the core is at least as large as the collection of competitive equilibrium allocations.We con.rm this for a standard model featuring land. Next we consider the public land ownership version of the...

The Changing Distribution of Firms and Workers Across Cities
Puga, Diego - 2017
This paper explores the changing distribution of firms and workers across cities. Cities have become increasingly specialized by function rather than sector, with business services, management and innovation concentrating in large urban areas and manufacturing dispersing across smaller cities...
