This paper expands the common-pool resource (CPR) game of Walker et al. (1990) to incorporate spatial structure with two spatially linked common-pool resources. Subjects participated in a five-player common-pool resource game under three alternative spatial structures (non-spatial,...

What explains the spatial distribution of wages across US counties? I find that two of the most important factors are spatial technology diffusion and externalities due to the aggregate scale of production. One empirical finding supporting the importance of spatial technology diffusion is that...

I formulate and estimate a model of externalities within countries and technological interdependence across countries. I find that external returns to scale to physical capital within countries are 8 percent; that a 10 percent increase of total factor productivity of a country's neighbors raises...

This paper develops a growth model with physical and human capital externalities to- gether with technological interdependence between economies. It leads to a spatial autore- gressive reduced form for the convergence equation characterized by parameter heterogeneity. A locally linear spatial...
