The Effects of Monetary Policy in the Euro Area

This paper presents evidence on the monetary transmission processin the euro area, based on macroeconomic data and on micro dataon banks. According to the estimations of macro vector autoregressionand macroeconometric models, a monetary policy tightening significantlyreduces output and—after a time lag—also prices.The effect on output is temporary, while that on prices is permanent.Clear patterns of significant asymmetries in the monetary policyeffects across countries do not emerge. The estimations basedon micro data on banks show that the main factor that determinesthe average bank's response to monetary policy is its degreeof liquidity: the lower its share of liquid assets in totalassets, the more strongly does a bank reduce its lending inresponse to a monetary tightening. Bank size does not emergeas an important factor for a bank's reaction to monetary policy.These results hold for virtually all member countries of theEuropean Monetary Union, despite the differences in their bankingsystems.
