Cities exist because of the productivity gains arising from clustering production and workers, a process called agglomeration. How important is agglomeration for aggregate growth? This paper constructs a dynamic stochastic general equilibrium model of cities and uses it to estimate the effect of...

Urban growth refers to the process of growth and decline of economic agglomerations. The pattern of concentration of economic activity, and its evolution, has been found to be an important determinant, and in some cases the result, of urbanization, the structure of cities, the organization of...

Most economic activity occurs in cities. This creates a tension between local increasing returns, implied by the existence of cities, and aggregate constant returns, implied by balanced growth. To address this tension, we develop a theory of economic growth in an urban environment. We show how...

Cities experience significant, near random walk productivity shocks, yet population is slow to adjust. In practise local population changes are dominated by variation in net migration, and we argue that understanding gross migration is essential to quantify how net migration may slow population...

Combining data from several sources, we build a database of home values, the cost of housing structures, and residential land values for 46 large U.S. metropolitan areas from 1984 to 2004. Our analysis of these new data reveal that since the mid-1980s residential land values have appreciated...

We combine publicly available data from Freddie Mac, the Decennial Census of Housing, and the Bureau of Economic Analysis to construct the first constant-quality aggregate price index for the stock of residential land in the United States. We uncover five main results: (a) since 1970,...

On March 11, 2011 the strongest recorded in Japan earthquake occurred which triggered a powerful tsunami and caused a nuclear accident in the Fukushima Daichi Nuclear Plant Station. The triple 2011 disaster has had immense impacts on people life, health and property, social infrastructure and...

On March 11, 2011, the strongest ever recorded in Japan earthquake occurred which triggered a powerful tsunami and caused a nuclear accident in Fukushima nuclear plant. The latter was a “manmade” disaster having immense impacts on people’s life, health, and property, infrastructure, supply...

We use Texas's constitutional amendment in 1997 that expanded the scope of home equity loans as a source of exogenous variation to estimate the effects of relaxing credit constraints on small businesses. We find, using standard panel data methods and restricted-use micro-data from the US Census...

Un grupo de investigadores especialistas en distintas áreas del conocimiento se reúne para imaginar los próximos cincuenta años. Se plantean el reto de pensar qué país encontraría un peruano que, tras un prolongado sueño, despertará en el año 2062. Proyectar escenarios futuros implica,...
