The Joint Dynamics of Sovereign Ratings and Government Bond Yields

Abstract
Can a negative shock to sovereign ratings invoke a vicious cycle of increasing government bond yields and further downgrades, ultimately pushing a country toward default? The narratives of public and political discussions, as well as of some widely cited papers, suggest this possibility. In this paper, we will investigate the possible existence of such a vicious cycle. We find no evidence of a bad long-run equilibrium and cannot confirm a feedback loop leading into default as a transitory state for all but the very worst ratings. We use a bivariate semiparametric dynamic panel model to reproduce the joint dynamics of sovereign ratings and government bond yields. The individual equations resemble Pesaran-type cointegration models, which allow for valid interference regardless of whether the employed variables display unit-root behavior. To incorporate most of the empirical features previously documented (separately) in the literature, we allow for different long-run relationships in both equations, nonlinearities in the level effects of ratings, and asymmetric effects in changes of ratings and yields. Our finding of a single good equilibrium implies the slow convergence of ratings and yields toward this equilibrium. However, the persistence of ratings is sufficiently high that a rating shock can have substantial costs if it occurs at a highly speculative rating or lower. Rating shocks that drive the rating below this threshold can increase the interest rate sharply, and for a long time. Yet, simulation studies based on our estimations show that it is highly improbable that rating agencies can be made responsible for the most dramatic spikes in interest rates.

The Euro Plus Pact: Competitiveness and External Capital Flows in the EU Countries
Hubert Gabrisch, K. Staehr
Journal of Common Market Studies,
Nr. 3,
2015
Abstract
The Euro Plus Pact was approved by the European Union countries in March 2011. The pact stipulates various measures to strengthen competitiveness with the ultimate aim of preventing accumulation of unsustainable external imbalances. This article uses Granger causality tests to assess the short-term linkages between changes in relative unit labour costs and changes in the current account balance for the period 1995–2011. The main finding is that changes in the current account balance precede changes in relative unit labour costs, while there is no discernible effect in the opposite direction. This suggests that capital flows from the European core to the periphery contributed to the divergence in unit labour costs across Europe prior to the global financial crisis. The results also suggest that the measures to restrain unit labour costs may have only limited effect on the current account balance in the short term.

The Joint Dynamics of Sovereign Ratings and Government Bond Yields
Makram El-Shagi, Gregor von Schweinitz
Abstract
In the present paper, we build a bivariate semiparametric dynamic panel model to repro-duce the joint dynamics of sovereign ratings and government bond yields. While the individual equations resemble Pesaran-type cointegration models, we allow for different long-run relationships in both equations, nonlinearities in the level effect of ratings, and asymmetric effects in changes of ratings and yields. We find that the interest rate equation and the rating equation imply significantly different long-run relationships. While the high persistence in both interest rates and ratings might lead to the misconception that they follow a unit root process, the joint analysis reveals that they converge slowly to a joint equilibrium. While this indicates that there is no vicious cycle driving countries into default, the persistence of ratings is high enough that a rating shock can have substantial costs. Generally, the interest rate adjusts rather quickly to the risk premium that is in line with the rating. For most ratings, this risk premium is only marginal. However, it becomes substantial when ratings are downgraded to highly speculative (a rating of B) or lower. Rating shocks that drive the rating below this threshold can increase the interest rate sharply, and for a long time. Yet, simulation studies based on our estimations show that it is highly improbable that rating agencies can be made responsible for the most dramatic spikes in interest rates.

The Euro Plus Pact: Cost Competitiveness and External Capital Flows in the EU Countries
Hubert Gabrisch, K. Staehr
Abstract
The Euro Plus Pact was approved by 23 EU countries in March 2011 and came into force shortly afterwards. The Pact stipulates a range of quantitative targets meant to strengthen cost competitiveness with the aim of preventing the accumulation of external financial imbalances. This paper uses Granger causality tests and vector autoregressive models to assess the short-term linkages between changes in the relative unit labour cost and changes in the current account balance. The sample consists of annual data for 27 EU countries for the period 1995-2012. The main finding is that changes in the current account balance precedes changes in relative unit labour costs, while there is no discernible effect in the opposite direction. The divergence in unit labour costs between the countries in Northern Europe and the countries in Southern and Eastern Europe may thus partly be the result of capital flows from the core of Europe to the periphery prior to the global financial crisis. The results also suggest that the measures in the Euro Plus Pact to restrain the growth of unit labour costs may not affect the current account balance in the short term.

The Regional Distribution of Foreign Investment in Russia: Are Russians more Appealing to Multinationals as Consumers or as Natural Resource Holders?
K. Gonchar, Philipp Marek
Economics of Transition and Institutional Change,
Nr. 4,
2014
Abstract
This article conducts a plant-level study of the factors affecting foreign direct investment (FDI) inflow to a large opening economy endowed with specific factor advantages. We conclude that the distribution of FDI in Russian regions depends on market access and can be most notably described by the knowledge-capital framework. Factor endowments built by natural resources are more successful in explaining the location decisions of export–platform affiliates. The impact of natural resources depends on how the availability of these resources is measured. The results reject the crowding out effects of resource FDI and prove co-location mode, when service investments are attracted to resource-rich regions. Labour cost advantages better explain the preferences of non-trading service affiliates.

The Determinants of Inward Foreign Direct Investment in Business Services Across European Regions

Abstract
The paper accounts for the determinants of inward foreign direct investment in business services across the EU-27 regions. Together with the traditional variables considered in the literature (market size, market quality, agglomeration economies, labour cost, technology, human capital), we focus on the role of forward linkages with manufacturing sectors and other service sectors as
attractors of business services FDI at the regional level. This hypothesis is based on the evidence that the growth of business services is mostly due to increasing intermediate demand by other services industries and by manufacturing industries and on the importance of geographical proximity for forward linkages in services.
To our knowledge, there are no studies investigating the role of forward linkages for the location of FDI. This paper aims therefore to fill this gap and add to the FDI literature by providing a picture of the specificities of the determinants of FDI in business services at the regional level. The empirical analysis draws upon the database fDi Markets, from which we selected projects having as a destination NUTS 2 European regions in the sectors of Business services over the period 2003-2008. Data on FDI have been matched with data drawn from the Eurostat Regio
database. Forward linkages have been constructed using the OECD Input/Output database. By estimating a negative binomial model, we find that regions specialised in those (manufacturing) sectors that are high potential users of business services attract more FDI than other regions. This confirms the role of forward linkages for the localisation of business service FDI, particularly in the case of manufacturing.
