We study innovation and the resulting Schumpeterian economic growth that this innovation gives rise to in a model with N heterogeneous regions. For each region i where i=1,...,N, our analysis leads to five findings. First, we define the balanced growth path (BGP) allocations and the equilibrium...

We provide empirical evidence of the dynamics of city size distribution for the whole of the twentieth century in U.S. cities and metropolitan areas. We focus our analysis on the new cities that were created during the period of analysis. The main contribution of this paper, therefore, is the...

We use a dynamic model to study the effects of technology and learning on the long run economic growth rates of a leading and a lagging region. New technologies are developed in the leading region but technological improvements in the lagging region are the result of learning from the leading...

This paper introduces cultural gravity as a new concept for analyzing socio-economic disparities among immigrants. It tests the existence of cultural gravity effects on the geographic concentration and human capital productivity of immigrants. Using cultural distance as a proxy for the local...

This paper analyses the determinants of growth of American cities, understood as growth of the population or of per capita income, from 1990 to 2000. This empirical analysis uses data from all cities with more than 25,000 inhabitants in the year 2000 (1154 cities). The results show that while a...

This paper aims to offer an advanced assessment methodology for sustainable national energy-environment-economic efficiency strategies, based on an extended Data Envelopment Analysis (DEA) in which distinct countries are regarded as Decision Making Units (DMUs). The aim is to show how much...

This paper reconsiders the evolution of the growth of American cities since 1790 in light of new theories of urban growth. Our null hypothesis for long-term growth is random growth. We obtain evidence supporting random growth against the alternative of mean reversion (convergence) in city sizes...

This paper analyses in detail the features offered by a function which is practically new to Urban Economics, the q-exponential, in describing city size distributions. We highlight two contributions. First, we propose a new and simple procedure for estimating their parameters. Second, and more...

Japan is faced with a gFukushima f problem, meaning a nuclear accident leading to electrical power shortage. This problem relates to a non-balanced gEnergy-Environment-Economic h policy which does not, but should incorporate gelectrical power saving h, glow carbon emission h, and geconomic...

According to Oswald's hypothesis homeowners experience more problems in finding a new job after becoming unemployed because their moving costs are higher than those of renters. Empirical research has revealed that this effect is counteracted by the job search behavior of unemployed homeowners:...
