Trade Imbalances and Fiscal Policy in the Eurozone: An Analysis of Economic Interrelations with a Global Supermultiplier Input-Output Model
研究了欧元区核心国与外围国之间的贸易失衡问题，通过全球超级乘数投入产出模型分析财政政策扩张对贸易平衡的影响，发现仅靠凯恩斯主义措施难以替代新自由主义政策。
We investigate the potential of European-wide Keynesian policies as an alternative to the current neoliberal response to trade imbalances. In particular, we examine the implications for balancing trade of an uncoordinated fiscal policy expansion, and whether coordinated reflationary measures in core Eurozone countries could promote balanced trade and significant growth in peripheral countries. Accordingly, we analyse the structural interdependencies in income and trade between peripheral and central Eurozone countries, such as Spain and Germany. To this end, we employ a comprehensive set of accounting multipliers derived from a Keynesian supermultiplier model that accounts for interindustrial and interregional relations in a global setting. Computations rely on global input-output tables and national accounts that cover the years 1995 to 2014. We conclude that scepticism about the effectiveness of relying solely on Keynesian measures as an alternative to neoliberal policies in Europe is in order.
