The Optimal Currency Area theory stresses the importance of co-movement of the business cycles of member states in order for the common currency to be successful. Yet, the identification of (European) business cycles has been inconclusive and is complicated by the enlargement to the new member...

This paper investigates the uncovered interest parity hypothesis in an unusual way. We provide empirical evidence on the efficiency of capital markets using a time domain approach. However, a common prediction from theoretical models is that inefficient capital markets cause greater volatility...

In this paper, we show how to derive the spectra and cross-spectra of economic time series from an underlying econometric or VAR model. This allows us to conduct a proper frequency analysis evaluation of economic and financial variables on a reduced sample of data, without it being ruled out by...
