Empirical studies find that fluctuations in output and other macroeconomic aggregates are positively related across countries. Economic theory focuses on two main explanations: common shocks and common transmission mechanisms. In this paper, we conduct an empirical analysis of the international influences, specifically from the U.S. and E.U. on the Greek business-cycle. First, we provide an in-depth analysis of the Greek economy, summarizing crucial aspects and trends by means of relevant econometric techniques such as business cycles extraction and periodization based on filtering, spectral analysis and causality tests. Next, we assess the long-run equilibriums of the Greek economy with the rest of the E.U. countries and the U.S. economy by means of a Vector Error Correction model. Our results imply a significant shift in the long-run equilibriums of the Greek economy towards increasing convergence rates with the U.S. economy after the implementation of the common monetary policy and increasing convergence rates towards the peripheral countries of the E.M.U. Also, the Greek GDP fluctuations are found to be caused, to a certain extent, by the EMU and US fluctuations, implying a transmission mechanism of business cycles from the EMU and the US to the Greek economy.
