China’s real estate has been a key engine of its sustained economic expansion. This paper argues, however, that even before the Covid-19 shock, a decades-long housing boom had given rise to severe price misalignments and regional supply-demand mismatches, making an adjustment both necessary...

Until now, thinking on open economy macroeconomics has been largely schizophrenic. When it comes to analyzing exchange rate dynamics, an empirically-minded economist abandons modern current account models which, while theoretically coherent, fail to address the awkward reality of sticky nominal...

This paper reviews the large and growing literature which tests PPP and other models of the long-run real exchange rate. We distinguish three different stages of PPP testing and focus on what has been learned from each. The most important overall lesson has been that the real exchange rate...

This paper studies the implications of central bank credibility for long-run inflation and inflation dynamics. We introduce central bank lack of commitment into a standard non-linear New Keynesian economy with sticky-price monopolistically competitive firms. Inflation is driven by the...

This paper offers a new approach to measuring the size of the informal economy based on VAT data for the European Union. Although data intensive, our EVADE measure is simpler and more transparent than existing measures. EVADE also shows more variation across coun- tries of Europe than earlier...

This paper provides new estimates of the housing stock, construction rates and price developments by city tier in China in order to understand where excess supply might be concentrated, and the implications of any significant contraction. We also update estimates of the size of China’s rapidly...
