BUBBLES DETECTION FOR INTER-WAR EUROPEAN HYPERINFLATION: A THRESHOLD COINTEGRATION APPROACH.

This paper undertakes an empirical investigation into the existence of inflationary bubbles during the inter-war European hyperinflation for Germany, Hungary, Poland and Russia. Our Monte Carlo simulations show that the residual-based threshold cointegration methodology of Caner and Hansen (2001) is better able to detect periodically collapsing bubbles. Moreover, this methodology possesses greater power against nonlinear stationary alternatives in a finite sample than several commonly used cointegration tests that do not allow for multiple regime shifts. The empirical results of the threshold cointegration tests provide evidence of stationary, regime-switching processes in money demand dynamics, but suggest that there are no inflationary bubbles in any of the countries.
