We propose a new and time-varying optimum currency area (OCA) index for the euro area in assessing the evolution of the OCA properties of the monetary union from an international business cycle perspective. It is derived from the relative importance of symmetric vs. asymmetric shocks that result...

This paper presents an empirical assessment of the endogenous optimum currency area theory. Frankel and Rose (1998) study the endogeneity of a currency union through the lens of international trade flows. Our study extends Frankel and Rose's model by using FDI flows to test the original theory...

This paper examines whether macroeconomic convergence is an automatic outcome of forming a currency union by combining an analysis of real interest parity (RIP) in the EU with the argument for the endogeneity of the Optimum Currency Area (OCA) criteria. Using the DF-GLS and the CIPS* panel unit...
