Macroeconomic variables and the sovereign risk premia in EMU,non-EMU EU,and developed countries

This project studies and models key macroeconomic variables and their impact on sovereign risk premia across select European economies and developed countries. The sample is divided into three groups of countries: those in the European Monetary Union (EMU); the standalone economies outside the EMU but members of the broader European Union (EU); and other developed economies. The main subject of examination across all three groups is the impact of macroeconomic variables on sovereign borrowing costs. EU countries have experienced high financial stress and a rapid rise in the credit default swaps (CDS) spreads during the EMU debt crisis. A nonlinear vector smooth transition autoregressive model is applied to investigate such a regime change in the finance-output link using sovereign CDS and industrial production index. The paper finds that regime-switching takes place rather suddenly in most EMU countries. The study concludes that due to the potential spillover effects in the EU as a whole, the individual country macroeconomic indicators were less reflected in the financial stress and spillover and contagion effects became dominant.     

Transmission channels of international financial crises to African stock markets: the case of the euro sovereign debt crisis

This article investigates the effects of the European sovereign debt crisis on African stock markets within a Bayesian shrinkage VAR framework. This method allows us to consider both North African and Sub-Saharan African stock markets, and provides a flexible parsimonious specification. The results reveal varying reactions of the impulse response functions. The most exposed African stock markets are those of Egypt, South Africa and Mauritius, while the least affected stock market is, surprisingly, that of Ivory Coast. Our analysis shows that, in addition to direct transmission, several macroeconomic and market channels, such as commodities, exports, and exchange rates, are relevant. Specifically, countries with strong commercial links to European countries will be most impacted by the crisis. The severity of transmission also depends on the country’s dependence on commodities.     

International trade and macroeconomic dynamics: The case of U.S. bilateral trade with G-7 countries

The short- and long-run effects of exchange rates, income, interest rates and government spending on U.S. bilateral trade with the other G-7 countries are investigated using an autoregressive distributed lag (ARDL) model. The primary contribution of this study is to consider separating the analysis of exports and imports in an integrated model that empirically encompasses four major schools of thoughts – elasticity, Keynesian income, absorption and monetary approaches – in order to identify macroeconomic linkages to U.S. bilateral trade with the other G-7 countries accurately. Results suggest that, in both the short- and long-run, U.S. imports and exports are highly sensitive to changes in U.S. and foreign income, while U.S. imports and exports are relatively insensitive to changes in bilateral exchange rate. It is also found that both exports and imports are more responsive to changes in government spending than changes in interest rates in both the short- and long-run.     

Banking solvency determinants in the EU: a model based on stress tests

Using a multilevel regression model, this article aims to find determinants of banking solvency in the European Union. The endogenous variable is defined as the capital ratio determined by stress tests. Both internal (financial ratios and sovereign debt exposures) and external (macroeconomic indicators) variables are proposed as covariates. The results reveal that capitalization, earnings, assets structure and exposure to PIIGS (Portugal, Italy, Ireland, Greece and Spain) sovereign debt are significant among the former, and economic growth, interest and exchange rates, and real estate prices among the latter.     

An Alternative Approach to the Institutional Economics of the Eurozone Crisis

I argue that the Eurozone crisis is neither a crisis of European sovereigns in the sense of governmental over-borrowing, nor a crisis of sovereign debt market over-lending. Rather, it is a function of the “sovereign debt market” institution itself. Crisis, I argue, is not an occurrence, but an element fulfilling a precise technical function within this institution. It ensures the possibility of designating — in the market’s day-to-day mechanisms rather than analytical hindsight — normal (tranquil, undisturbed) market functioning. To show this, I propose an alternative view on the institutional economics of sovereign debt markets. First, I engage literature on the emergent qualities of the institutions “market” and “firm” in product markets, concluding that the point of coalescence for markets is the approximation of an optimal observation of consumer tastes. I then examine the specific institution “financial markets,” where the optimal observation of economic fundamentals is decisive. For the specific sub-institution “sovereign debt market,” I conclude that the fundamentals in question — country fundamentals — oscillate between a status of observable fundamentals outside of markets and operationalized fundamentals influenced by market movements. This, in turn, allows me to argue that the specific case of the Eurozone crisis is due to neither of the two causes mentioned above. Rather, the notion of “crisis” takes on a technical sense within the market structure, guaranteeing the separation of herd behavior and isomorphic behavior on European sovereign debt markets. By the same token, the so-called Eurozone crisis ceases to be a crisis in the conventional sense.

Financial supply cycles in post-transition Europe – introducing a composite index for financial supply

This paper introduces a new composite index – the financial supply index (FSI) – measuring the level of supply of foreign capital to small open economies. FSI is estimated on a sample of 11 EU new member states (NMS) applying Kalman filtering, principal components and variance-equal weights. Results indicated that the main drivers of financial supply to NMS are externally determined, with economic sentiment and business climate in the Eurozone carrying the highest weight. FSI proved to have a good predictive power for debt inflow dynamics. In addition, we create a new indicator – the Refinancing Risk Ratio, which relates the supply and demand for foreign capital – to quantify the external refinancing conditions and risk faced by the government. We distinguish between two recent episodes of high refinancing risk – one during the global crisis, and the other during the European sovereign debt crisis – but the episodes significantly differ in nature.     

Monetary and Fiscal Stabilization of Demand Shocks Within Europe

This paper examines alternative macroeconomic stabilization rules for demand shocks, for a single open economy, and for an integrated European region. These questions are tackled in two ways. First a very simple macroeconomic model is used to focus on intercountry interconnections. Then the effects of shocks are simulated using the McKibbin Sachs MSG2 global economic model. The theoretical model analyzes just how much larger the disturbances caused by asymmetric shocks might be in a European Monetary Union, as compared with outcomes under floating exchange rates, especially (1) if rigid central monitoring and discipline of the fiscal policy prevents the full operation of the inbuilt fiscal stabilizers within individual European countries, and (2) if European monetary policy does not concern itself with fully European objectives. Simulations with the MSG2 model bear out the significance of these risks. They show that a demand shock like GEMU can have strongly negative effects on output in other European countries if either interest rates are raised to counter the demand shock in the originating country, or if, for some reason, fiscal stabilization is not allowed to be as strong as the inbuilt fiscal stabilizers.     

Increase in home bias in the Eurozone debt crisis: The role of domestic shocks

One of the most striking consequences of the recent episode of sovereign debt market stress in the Eurozone has been the increase in the share of public debt held by the domestic sector in fragile economies. However, the causes and potential consequences of this increase were only given scarce attention in the literature on the Euro area sovereign debt crisis. In order to fill this gap, we first determine the shocks that impact the variation in the share of sovereign debt held at home in an SVAR model on a sample of Eurozone countries between 2002 and 2014, distinguishing between external and domestic shocks. Thanks to several alternative tests, we show that home bias in sovereign debt responds positively to country-specific fundamentals and expectation shocks but we find no evidence that the increase in home bias is destabilizing per se in the short-run. Second, a stylized theoretical model backed by the empirical results predicts that the consequences for sovereign debt crisis depend on the relative impact of domestic initial destabilizing shocks and increased home bias. The analysis suggests that an increase in home bias in times of sovereign debt stress, despite reflecting deteriorating fiscal conditions, may make default less likely.     

Debt uncertainty and economic growth: evidence from five highly indebted Eurozone countries

The goal of this study is to examine the relationships between economic growth and debt uncertainty by applying the threshold generalized autoregressive conditional heteroscedasticity modelling methodology in five Eurozone countries spanning the period 2001–2013. The results document that during the European fiscal crisis period, debt uncertainty exerts a significant negative effect on economic growth across all five Eurozone countries that experienced the deterioration of their fiscal positions.     

Mispricing of Risk in Sovereign Bond Markets with Asymmetric Information

The likelihood that a government will repay its sovereign debt depends both on the amount of debt it issues and on the government's future ability to repay. Whilst the former is publicly observable, the government may have more information about the latter than investors. This paper shows that this asymmetric information problem impairs the market's ability to differentiate economies according to their fiscal sustainability, and can lead to a disconnect between bond prices and default risk. The model can help rationalise the behaviour of Eurozone bond prices prior to the recent European sovereign debt crisis.     

The Governance of a Fragile Eurozone

When entering a monetary union, member countries change the nature of their sovereign debt in a fundamental way; that is, they cease to have control over the currency in which their debt is issued. As a result, financial markets can force these countries’ sovereigns into defaulting. This makes the monetary union fragile and vulnerable to changing market sentiments. It also makes it possible that self‐fulfilling multiple equilibria arise. I analyse the implications of this fragility for the governance of the Eurozone. I argue that the role of the European Central Bank as a lender of last resort is crucial in reducing the fragility of the Eurozone. In addition, steps towards a budgetary union are key in structurally strengthening the union.     

PIGS or Lambs? The European Sovereign Debt Crisis and the Role of Rating Agencies

This paper asks whether rating agencies played a passive role or were an active driving force during Europe??s sovereign debt crisis. We address this by estimating relationships between sovereign debt ratings and macroeconomic and structural variables. We then use these equations to decompose actual ratings into systematic and arbitrary components that are not explained by previously observed procedures of rating agencies. Finally, we check whether systematic, as well as arbitrary, parts of credit ratings affect credit spreads. We find that both do affect credit spreads, which opens the possibility that arbitrary rating downgrades trigger processes of self-fulfilling prophecies that may drive even relatively healthy countries towards default.     

European financial crisis and bank productivity: evidence from Eastern European Countries

The paper examines the productivity levels of the largest banks operating in the Eastern European countries over the period of the ongoing European financial crisis. Specifically, the analysis covers the periods of U.S. subprime crisis, the global financial crisis and the sovereign debt crisis. By adopting a fully nonparametric framework, it provides a probabilistic version of a directional input-oriented Malmquist productivity index alongside with its main decomposition. The results from the analysis suggest that banks have faced a deterioration of their productivity levels between the examined periods. It is evident that during the initiation of European sovereign debt crisis, the banks have weakened their ability to utilize efficiently their inputs of production and their ability to realize scale economies.     

Institutional arrangements and public debt threshold limits

Inter-governmental Organisations, such as the IMF and OECD, advocate a medium-term reduction in deficit spending and public debt accumulation among advanced economies to satisfy conditions of fiscal sustainability. Buttressing the need for fiscal austerity, Reinhart and Rogoff claim to have identified a so-called tipping point, beyond which public debt accumulation negatively affects economic growth. While recent data seem to indicate that some Eurozone (non-sovereign) economies have reached a tipping point, for other advanced (sovereign) economies, such as the US, UK and Japan, this is not clear. The mainstream tipping point literature however does not recognise the importance of institutional arrangements for the conduct of fiscal and monetary policy. Furthermore, the literature sheds little light on the transmission mechanism between high public debt and low economic growth. This article draws on the principles of Modern Monetary Theory to discuss institutional arrangements and to justify the theoretical and empirical focus on Eurozone economies. The empirical analysis unpacks the transmission mechanism(s) to reveal that Eurozone economies have reached a public debt threshold limit with respect to long-term interest rates.     

Fiscal devaluation and economic activity in the EU

In the aftermath of the global financial crisis, a fiscal devaluation (hereafter, FD), understood as a shift in taxation from labour to consumption, has been debated as a possible tool for restoring competitiveness, particularly in peripheral countries of the Eurozone. We contribute to this debate. Based on a set of panel and spatial panel models for the EU 27 over the period 1995–2014, we find that FD works, especially where economic activity is heavily subdued and in sectors more exposed on external competition. FD increases value added in exports, improves net exports, accelerates GDP and employment growth, and decelerates growth in labour costs. These effects are nonlinear; they are stronger in the members of the Eurozone and weaker in countries with either more coordinated or more centralised wage bargaining processes or more generous unemployment benefits. The magnitude of these effects is dampened by strict regulatory barriers: they are weaker in countries with higher barriers to entrepreneurship, trade and investment. Most importantly, FD is not a beggar thy neighbour policy, at least in the EU. In our sample, the aggregate demand (‘cooperative’) effect of unilateral FD, which is beneficial for neighbouring countries, outweighs by far the expenditure switching (‘competitive’) effect, which comes at the expense of other countries’ competitiveness. FD implemented in one country can benefit other countries, provided that they are strongly integrated in global value chains. These findings are robust to changes in the estimation methods, the sample composition, the set of explanatory variables and the selection of a spatial weight matrix.     

So alike,yet so different: Comparing fiscal multipliers across EU members and candidates

We estimate, using a Panel Vector Autoregressive approach and data from 2001Q1 to 2017Q1, the fiscal multipliers of the European Union (EU) members and candidates. These countries are grouped according to their stages of integration: original members, new Eurozone members, and candidates for the Eurozone and the EU itself. For each group, we assess the impact of a positive spending shock (expansionary) or a positive tax shock (contractionary) on GDP. Our findings suggest that: (i) rising government spending increases GDP in both the EU and Eurozone candidates (Keynesian multipliers), but slightly decreases it in the Eurozone members (non-Keynesian multipliers); (ii) higher taxes are associated with mixed results in terms of GDP dynamics - both increases and decreases in terms of GDP are found - in the four country groups (suggesting the presence of Keynesian and non-Keynesian multipliers). Overall, these outcomes indicate that spending multipliers are, compared to tax multipliers, more sensitive to European Union or Eurozone membership.     

Emerging market sovereign spreads,global financial conditions and U.S. macroeconomic news

We investigate the impact of global financial conditions, U.S. macroeconomic news and domestic fundamentals on the evolution of EMBI spreads for a panel of 18 emerging market (EM) countries using daily data. To this end, we consider not only the conventional panel cointegration procedures but also the recent common correlated effects method to tackle cross-section dependence that may stem from common global shocks such as contagion. The results suggest that the long-run evolution of EMBI spreads depends on global financial conditions, crises contagion and domestic fundamentals proxied by sovereign ratings. The results from panel equilibrium correction models suggest that EMBI spreads respond substantially also to U.S. macroeconomic news and changes in the Federal Reserve's target interest rates. The magnitude and the sign of the effect of the U.S. news, however, crucially depend on the state of the U.S. economy, such as the presence of inflation dominance.
