We use data on wages and rents in different U.S. cities to assess the amenity effects on production and consumption of cultural diversity as measured by diversity of countries of birth of city residents. We show that US-born citizens living in metropolitan areas where the share of foreign-born...

Why do cities differ so much in productivity? We document that most of the measured dispersion in productivity across US cities is spurious and reflects granularity bias: idiosyncratic heterogeneity in plant-level productivity and size, combined with finite plant counts. As a result, economies...

n this paper we determine the main driving forces underlying the structural transformation and urbanization process in rapidly industrializing countries. We use a dynamic, small open economy model with an abundant supply of surplus labor in rural areas, two types of traded goods manufactured in...

Larger cities typically give rise to two opposite effects: tougher competition among firms and higher production costs. Using an urban model with substitutability of production factors and pro-competitive effects, I study the response of the market outcome to city size, land-use regulations, and...

In explaining the uneven spatial distribution of economic activity, urban economics and new economic geography (NEG) dominate recent research in economics. A main difference between these two approaches is that NEG stresses the role of spatial linkages whereas urban economics does not do so. We...

I define a composite amenity that provides aesthetic and consumption value to local residents: Urbanity. A novel data set of geo-tagged photos shared in internet communities serves as a proxy for urbanity. From the spatial pattern of house prices and photos I identify the value of urbanity in...

This paper analyzes a closed, essentially linear polycentric city with homogenous households who probabilistically select their workplace and residence locations. The study utilizes a continuous logit model to describe household location choices. In contrast to the classic urban model with...

We consider taxation by a Leviathan government and by a utilitarian government in the presence of heterogeneous locations within a country, when migration from one country to another is and is not possible. In a closed economy, a utilitarian government may transfer income from the poor to the...

This paper surveys the various forms of market failure that can arise when innovating entrepreneurs consider entering an industry, and outlines possible implications for public policy. Externalities can arise from entrepreneurial activities such as spillover benefits from new innovations and...

This paper proposes a simple partial equilibrium model to investigate the effects of government policy on venture capital backed investments. Giving up an alternative career, entrepreneurs focus their effort on a single, high risk venture each. Venture capitalists acquire an equity stake and...
