Further we show that such results can be misleading unless age-sex-specific labour-force changes are explicitly considered. We then analyze the performance of the Canadian regional labour markets as an example of the proposed pro...

However, canonical versions of theories of agglomeration – spill-overs, cost advantages and improved match quality – all predict that establishments should be smaller in cities. The paper proposes a theory based on monopsony in labour markets that can explain the stylized ...
