Actual monetary policy independence in a small open economy: the Polish perspective

The aim of this article is to examine the actual degree of monetary policy independence in a small open economy with floating exchange rate that is integrated with the world economy. It is frequently argued that for such a country the primary cost of participation in a currency area is the loss of monetary policy independence. The article raises the question if the proposition of monetary independence provided by floating exchange rate applies to a small open economy, operating within highly liberalised capital flows and highly integrated financial markets. We examine the actual degree of monetary policy independence in Poland using a vector error correction mechanism model and the data for the years 2001–2014. We obtain evidence pointing to the lack of such independence, and we show that this result is robust to extensive changes in specification, including impulse saturation.
