On the bi-directional causal relationship between public debt and economic growth in EMU countries [WP]

Abstract

New evidence is presented on the possible existence of bi-directional causal relationships between public debt and economic growth in both central and peripheral countries of the European Economic and Monetary Union. We test for heterogeneity in the bi-directional Granger-causality across both time and space during the period between 1980 and 2013. The results suggest evidence of a “diabolic loop” between low economic growth and high public debt levels in Spain after 2009. For Belgium, Greece, Italy and the Netherlands debt has a negative effect over growth from an endogenously determined breakpoint and above a debt threshold ranging from 56% to 103% depending on the country.
