Summary: | 博士 === 國立政治大學 === 經濟學系 === 105 === Since the global recession in 2008, the economic performance of the Euro area has declined significantly. In particular, there have been great differences in the economic performance among member states in the Euro area. In this dissertation, we attempt to address the issue of economic stability by focusing on two key features: the trade openness and the fiscal fundamentals among member states. In Chapter 2, we compare the impacts of the adverse shocks on countries with different degrees of openness under the monetary union regime, and our finding shows that the monetary union will result in a greater decline in output if the monetary authority attaches a higher weight to output stabilization. In Chapter 3, we build a two-country DSGE model representing a monetary union with both short-term and long-term government bonds. We deduce that the ECB’s public sector purchase programme (PSPP) has asymmetric macroeconomic effects on member states under different fiscal fundamentals. In Chapter 4, we set up an optimal monetary policy model of a monetary union. We find that the differences in the economic performance of individual member states will influence the union-wide welfare. Comparing our results with classical literature of optimal monetary policy at zero lower bound, by adding the PSPP, our study indeed reflects lower volatility of the union-wide economy under either discretion or commitment.
