We combine census and establishment-level data for 2001-2017 to study the impact of mass layoffs of big manufacturing plants on city-level population and its composition in Canada. We find that manufacturing plant closures and downsizing lead to a decline in subsequent population growth,...

We extend the two-country model by Krugman (1980) to a multi-country set-up and show that the `home-market effect' highlighted with two countries does not readily extend to such a more general setting. In particular, we prove that the most important result, namely the disproportionate causation...

Using a large sample of US urban areas, we provide systematic evidence that mean household income rises with city ('agglomeration'), that this effect is stronger for the top of the income distribution ('polarization'), and that household income inequality increases at a decreasing rate in city...

We develop a two-region population growth model of economic geography and show that a process of urbanization has a substantial impact on the evolution of manufacturing real wages. Whereas real wages decline as the population increases when the spatial structure of the economy is fixed, they...

We investigate where cities are located in a spatial economy and why they tend to get 'locked-in' at particular sites. Building on Fujita and Krugman (1995) we show that geography and/or transportation technology must exhibit some 'non-smoothness' for cities to possibly become 'locked-in' in...

Large cities produce more output per capita than small cities. This higher productivity may occur because more talented individuals sort into large cities, because large cities select more productive entrepreneurs and firms, or because of agglomeration economies. We develop a model of systems of...
