"Causality and contagion in peripheral EMU public debt markets: a dynamic approach"

Our research aims to analyze the causal relationships in the behavior of public debt issued by peripheral member countries of the European Economic and Monetary Union (EMU), with special emphasis on the recent episodes of crisis triggered in the eurozone sovereign debt markets since 2009. With this goal in mind, we make use of a database of daily frequency of yields on 10-year government bonds issued by five EMU countries (Greece, Ireland, Italy, Portugal and Spain), covering the entire history of the EMU from its inception on 1 January 1999 until 31 December 2010. In the first step, we explore the pair-wise causal relationship between yields, both for the whole sample and for changing subsamples of the data, in order to capture the possible time-varying causal relationship. This approach allows us to detect episodes of contagion between yields on bonds issued by different countries. In the second step, we study the determinants of these contagion episodes, analyzing the role played by different factors, paying special attention to instruments that capture the total national debt (domestic and foreign) in each country.Sovereign bond yields, causality, time-varying contagion, euro area, peripheral EMU countries.

Con este objetivo, empleamos una base de datos de la frecuencia diaria de los rendimientos de los bonos gubernamentales a 10 años emitidos por cinco países de la UEM (Grecia, Irlanda, Italia, Portugal y España), que abarca toda la historia de la UEM desde su inicio el 1 de enero de 1999 al 31 diciembre de 2010. En la primera etapa, se explora la relación causal por pares entre los rendimientos, tanto para la muestra completa y para submuestras cambiantes de los datos, con el fin de capturar posible relación causal en función del tiempo. Este enfoque nos permite detectar episodios de contagio entre los rendimientos de los bonos emitidos por países distintos. En el segundo paso, se estudian los factores determinantes de estos episodios de contagio, el análisis del papel desempeñado por diferentes factores, prestando especial atención a los instrumentos que capturan la deuda nacional total (doméstica y extranjera) en cada país.Sovereign bond yields, Causality, Time-varying contagion, Euro area, Peripheral EMU countries, Rendimientos bonos soberanos, Causalidad, Contagio variable en el tiempo, Eurozona, Países periféricos UEM.

Public debt and economic growth: Further evidence for the euro area

This paper empirically investigates the short and long run impact of public debt on economic growth. We use annual data from both central and peripheral countries of the euro area (EA) for the 1961-2013 period and estimate a production function augmented with a debt stock term by applying the Autoregressive Distributed Lag (ARDL) bounds testing approach. Our results suggest different patterns across EA countries and tend to support the view that public debt always has a negative impact on the long-run performance of EA member states, whilst its short-run effect may be positive depending on the country

Granger-causality in peripheral EMU public debt markets: A dynamic approach

Our research aims to analyze the possible existence of Granger-causal relationships in the behavior of public debt issued by peripheral member countries of the European Economic and Monetary Union (EMU), with special emphasis on the recent episodes of crisis triggered in the eurozone sovereign debt markets since 2009. With this goal in mind, we make use of a database of daily frequency of yields on 10-year government bonds issued by five EMU countries (Greece, Ireland, Italy, Portugal and Spain), covering the entire history of the EMU from its inception on 1 January 1999 until 31 December 2010. In the first step, we explore the pair-wise Granger-causal relationship between yields, both for the whole sample and for changing subsamples of the data, in order to capture the possible time-varying causal relationship. This approach allows us to detect episodes of significant increase in Granger-causality between yields on bonds issued by different countries. In the second step, we study the determinants of these episodes, analyzing the role played by different factors, paying special attention to instruments that capture the total national debt (domestic and foreign) in each country

The causal relationship between debt and growth in EMU countries

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
