Recent evidence suggests that competitive intensity has been declining in the US. This column aims to contribute to our understanding of these trends in the euro area. It finds that, in contrast to the situation in the US, market power metrics have been relatively stable over recent years and mark-ups have marginally been trending down since the late 1990s. It suggests that more research on the sectoral level and with better data is necessary to analyse the complex welfare and policy implications of these developments.

The gravity equation has often been used to explain trade between regions or cities within countries. But it assumes that the distribution of industries is exogenous. This column explains how trade estimates are affected if we assume that large, centrally located cities attract more industries whose firms are more likely to export to other cities. Japanese data show exports from these cities are systematically underpredicted by aggregate gravity estimations, as the theory predicts.

What has caused the rapid decline in US manufacturing employment in recent decades? This column uses novel data to investigate the role of US multinationals and finds that they were a key driver behind the job losses. Insights from a theoretical framework imply that a reduction in the costs of foreign sourcing led firms to increase offshoring, and to shed labour.

Recent studies document a 30-year decline in various measures of dynamism in the US, manifested in a decline in the share of young firms as well as their share of job creation. This column shows that this has not been the case in Sweden. Young firms have been more prominent in the Swedish business sector than in the US in recent decades, and policies to encourage entrepreneurship are key to this.

The growth of large cities is often attributed to their proximity to exogenous, first-nature advantages. This column uses data on 450 Japanese cities to show that in fact, the regularity of agglomeration holds as a natural consequence of endogenous agglomeration and dispersion forces at the global or local level, rather than exogenous factors.
