What is the appropriate exchange rate at which neither domestic nor foreign firms gain an unfair competitive advantage? A new study examines whether the estimation methods currently being used are conducive to answering this question. It turns out that this is often not the case.

Can wage hikes in Germany contribute to a reduction in global trade imbalances? A new study answers this question. Applying a general equilibrium model, it shows that, although wage hikes in Germany reduce the country’s trade surplus, the quantitative effects are relatively small and depend on the European Central Bank’s monetary policy response.

Recently, many central banks have begun communicating not just their current monetary policy, but also its probable predicted future path. However, the effectiveness of this communication hinges on how strongly it is able to influence the inflation expectations of households and firms. A standard property of macroeconomic models is that expectations respond very strongly to such announcements. A new theoretical study shows that the effects are much smaller in a model capable of matching survey evidence on expectations formation.

Germany has the second lowest share of homeowners of all OECD countries. This is driven by housing policies that produce incentives to rent. New studies show that alternative policies could increase the homeownership rate and reduce wealth inequality.

Consumer goods prices systematically depend on product age. A new study analyses this dependence and shows that it plays an important role in aggregate inflation and the optimal inflation rate.
