14th DUBROVNIK ECONOMIC CONFERENCE The impact of selected structural reforms: Adjustment speed and distributional effects Annabelle Mourougane Lukas Vogel OECD Economics Department Introduction • Good understanding of the long-term effects of structural reforms • Little is known about short-term effects of reforms • Crucial from a political economy point of view Roadmap • Tools used in the paper • Delays of adjustment • Effects of existing market rigidities on the speed of adjustment • Interactions with monetary policy and international spillovers • Distributional effects of reforms Tools A set of complementary tools • Data on institutions provides us insights on ex-post effects of reforms • Models are useful for ex-ante assessments Macro-economic neo-Keynesian models DGE model Delays of adjustment The equilibrium unemployment rate and the contribution of institutions in the European Union Equilibrium unemployment per cent Replacement rate percentage point 10 5 9 4 8 3 7 2 6 1 0 5 1995 1996 1997 1998 1999 2000 2001 2002 Tax wedge percentage point 1995 2003 1996 percentage point 10 5 9 4 8 3 7 2 6 1 5 1997 1998 1999 2000 2001 2002 2003 2002 2003 Product market regulation 0 1995 1996 1997 1998 1999 2000 2001 2002 2003 1995 1996 1997 1998 1999 2000 2001 Note: The sample includes the 20 countries examined in Bassainini and Duval (2006) except Germany, Finland and Sweden.
