In 2013, the European Commission decided to ask for an in-depth analysis of the German current account surplus, arguing that it might be too large. German politicians responded that the German current account surplus is the cornerstone of Germany's well-being and reflects "a sign of the competitiveness of the German economy and global demand for quality products from Germany".

b. The German government decides to put into place a massive public investment programme. How do you expect the German current account to respond, if at all, and do you expect changes in other euro area countries' current accounts?
