We study how the import of older and more polluting technologies alters the relationship between output and environmental quality in developing countries within a vintage capital framework. Our results show that old technologies prolong the period until which pollution may eventually decrease...

We study the strategic behavior of two countries facing transboundary CO2 pollution under a differential game setting. In our model, the reduction of CO2 concentration occurs through the carbon capture and storage process, rather than through the adoption of cleaner technologies. Furthermore, we...

The paper investigates how urban primacy affects economic growth across countries. Using semi-parametric estimation techniques on a cross-country panel for the years 1960—90, an increasing relationship is unearthed between urban primacy and growth. This result holds even when limiting the...

This paper proposes to investigate the effect of spillovers on firms' R&D investment decisions. We develop an analysis merging the geographer's toolbox with standard econometric techniques. For a chosen sample of sectors, we test the existence of positive spatial autocorrelation at the level of...

The relationship between growth and pollution is studied through a vintage capital model, where new technologies are more environmentally friendly. We find that once the optimal scrapping age of technologies is reached, an economy may achieve two possible cases of sustainable development, one in...
