I explore the dynamics of national production in a two-sector, two country model with cross-sector mobility and forward-looking agents, when trade costs fall or when the news of a boom in a sector is learned. Using the phase diagram method, introduced by Baldwin 1999 in this type of...

This article analyzes empirically the main existing theories on income and population city growth: increasing returns to scale, locational fundamentals and random growth. To do this we implement a threshold nonlinearity test that extends standard linear growth regression models to a dataset on...

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...

The consanguine marriages and/or causine marriages are generally accepted and evaluated in light of the genetic problems. However, in the study, we aim to explain the effects on economic development and genetics problem of consanguine marriages and to investigate the relationship between...

The authors analyze employment growth in the metropolitan region and its relationship to employment in the United States as a whole. They identify a strong cyclical link between the region and the nation, punctuated by occasional, persistent shifts in the region's underlying growth rate. Some...

Identification of the strength of human capital externalities at the aggregate level is still not fully understood. The existing method may yield positive or negative externalities even if wages reflect marginal social products. We propose an approach that yields positive average human capital...

A number of empirical studies have tested the spatial mismatch hypothesis by examining the commuting times of blacks and whites. This note points out that the link between spatial mismatch and commuting times may be weak when employment probabilities decline as the distance from job site to...
