The Rise in US Non-tradeable Goods Prices: Facts and Explanations (with Germán Gutiérrez, Joseba Martinez and Thomas Philippon)

We document a large increase in US non-tradeable goods prices relative to EU non-tradeable prices between 1992 and 2018. This divergence in prices (i) did not occur in tradeable goods; (ii) cannot be attributed to divergent trends in nontradeable industry labor productivity or wages, which followed very similar paths in the US and EU; and (iii) drives the divergent evolution in manufacturing labor shares in the US and EU. A decomposition of changes in prices into changes in productivity, wages, technology and mark-ups (net of returns to scale) suggests that rising markups explain the bulk of the divergence in US non-tradeable prices.

Understanding barriers to trade in banking services: Evidence from the UK (with Shania Bhalotia and John Woods)

The financial sector is crucial for economic growth and financial services are increasingly traded across borders. The UK financial sector amounts to 10% of GDP, which is the largest in terms of share of GDP in the G7. Banking represents about half of the financial sector. However, little is known about the barriers to trade in services in general, and in these services in particular, and its consequent impact. This project studies how changes in non-tariff barriers affect trade in banking services by looking at the change in trade relations between the UK and the EU after Brexit, using data covering banks' cross-border activities. It aims to understand how changes in such barriers effect domestic and foreign activities of banks and productivity dynamics in the sector.
