There are two independent strands of literature on the geographic distribution of economic activities. One is the new economic geography that emphasizes product diversity, and the other is probabilistic migration that stresses taste heterogeneity in residential location. This article incorporates these two characteristics into a single framework, and analyzes how they affect the number and stab...

Canonical analysis of the classical general equilibrium model demonstrates the existence of an open and dense subset of standard economies that possess fully-revealing rational expectations equilibria. This paper shows that the analogous result is not true in urban economies under reasonable modifications for this field. An open subset of economies where none of the modified rational expectatio...

Ilan Dinstein,* Cibu Thomas, Marlene Behrmann, and David J. Heeger (Current Biology 18, R13–R18, January 8, 2008) On page R15 of this essay, the following sentence contains a problematic citation: ‘‘This circular interpretation has been taken to such an extreme that some recent studies now interpret any fMRI response in areas vPM and aIPS—for example, fMRI responses while observing moving shape...

This paper details the construction of a large-scale computable general equilibrium (CGE) model for a single U.S. region. The model contains detailed treatment of margins and taxes, features not typically given prominence in U.S. regional CGE models. The starting point for the core of the CGE model’s data base is information from IMPLAN, producers of regional I/O data at the U.S. county and sta...

Agglomeration can be caused by asymmetric information and a locational signaling effect: The location choice of workers signals their productivity to potential employers. The cost of a signal is the cost of housing at a location. When workers’ marginal utility of housing is negatively correlated with their productivity, skill-biased technological change causes a core-periphery bifurcation where...

The Northeast Under/Graduate Research Organization for Neuroscience (NEURON) was established 12 years ago in order to foster the training, education, and research of both undergraduate and graduate neuroscience students. NEURON hosts two annual conferences (Boston in the fall; New York City in the spring) to promote and support neuroscience training, education, and research. For 12 years, the o...

Lucas and Rossi-Hansberg (2002) and Fujita and Ogawa (1982, 1989) develop urban models in which economic activity self-organizes due to spillovers in production. However, Fujita and Ogawa (1982, 1989) show that rents and employment density are flat or falling as the city center is approached, while in the simulations of Lucas and Rossi-Hansberg (2002) rents rise at an increasing rate towards th...
