To that end we derive monetary policy reaction function from the central bank’s optimization problem. We find that the weights assigned to target variables were not constant over the period 1995-2003. The weight attached to inflation stabilization objective in the central bank’s loss function in Poland was equal to the weight assigned to output gap stabilization in the period 1995-1999 and the latter goal has been disregarded since 2000.17 pages180601 bytesapplication/pdfenMonetary policy reaction function; central bank’s loss function; New Keynesian Phillips curveReportEconomics
