A large literature characterises urbanisation as resulting from productivity growth attracting rural workers to cities. Incorporating economic geography elements into a growth model, we suggest that causation runs the other way: when rural workers move to cities, the resulting urbanisation produces technological change and productivity growth. Urban density leads to knowledge exchange and innovation, thus creating a positive feedback loop between city size and productivity that initiates sustained economic growth. This model is consistent with the fact that urbanisation rates in western Europe, most notably England, reached unprecedented levels by the mid-eighteenth century, the eve of the Industrial Revolution.

The Great Recession has strongly influenced employment patterns across skill and gender groups in EU countries. We analyse how these changes in workforce composition might distort comparisons of conventional measures of gender wage gaps via non-random selection of workers into EU labour markets. We document that male selection (traditionally disregarded) has become positive during the recession, particularly in Southern Europe. As for female selection (traditionally positive), our findings are twofold. Following an increase in the labour-force participation of less-skilled women, due to an added-worker effect, these biases declined in some countries where new female entrants were able to find jobs, whereas they went up in other countries which suffered large female employment losses. Finally, we document that most of these changes in selection patterns were reversed during the subsequent recovery phase, confirming their cyclical nature.

In the 1930s, countries fought destructive trade conflicts – now we have a similar situation, but the conflicts are taking place in the tax system. These conflicts arise out of the twin impacts of globalization and digitalization. Once upon a time, there was an implicit understanding of fairness in taxation, meaning how countries tax within their borders and how the tax burden is distributed. More specifically, companies and individuals were taxed based on their residence and consumption in the destination country. Such an approach worked while these events were mostly perceived as national. However, the world has changed, and in an increasingly globalized, digitalized, and mobile world, these understandings no longer appear to work smoothly, efficiently, and uncontentiously.
