Modelling the Eurozone as an Extraordinary Exchange Rate Union

The Trans-European Automated Real-Time Gross settlement Express Transfer system (TARGET) imbalances within the Eurozone can be interpreted as a sign of a missing balance of payments adjustment mechanism for the member countries. As the Eurozone lacks a fiscal union, in theory it is more of an exchange rate union or a system of fixed exchange rates than a monetary union. This paper will show why the TARGET is a crucial indicator for the Eurozone not being a monetary union but instead an exchange rate union, and why countries holding TARGET liabilities against the European System of Central Banks can be compared to a reserve currency country, like the US under the Bretton-Woods System.     

欧债危机成因与前景的制度分析

希腊等欧元区国家的主权债务危机可以说是欧洲区域一体化建设中的独特现象,其折射的是欧元区所存在的一个结构性问题：奉行单一货币政策和各国分散的财政政策,集中暴露出了欧洲货币一体化与欧洲福利资本主义的不相容、以及统一货币运行所要求的财政紧缩与欧元成员国经济增长和福利制度之间的矛盾与冲突;欧元不会就此瓦解,但欧债问题的最终解决困难重重;欧元的未来取决于自由与市场的回归欧洲,取决于欧盟的制度完善与欧式福利资本主义改革的成功与否。     

Contagion across Eurozone’s sovereign spreads and the Core-Periphery divide

This paper investigates the causes of disproportionate increases of sovereign yields with respect to the interest rate on the 10 years German Bund within the Eurozone. Empirical evidence drawn from the Bank for International Settlements dataset on banks’ portfolios shows that rapid financial integration, following the launch of the monetary union, resulted in excess exposure of Core countries’ banks in the Peripheral countries’ financial assets. In order to endogenize the possibility of contagion effects, we conduct econometric estimates through a Global Vector Autoregressive model, where each country’s spread depends upon all Eurozone countries’ spreads. Results show that after the burst of the financial crisis the Core countries’ sovereign yields are essentially determined by the international risk aversion, whereas the spreads of Peripheral countries mainly depend on fundamentals, namely the public debt/GDP ratio and the Real Effective Exchange Rate values with respect to the Eurozone average. These results are supported by the estimate of an impulse response analysis. Macroeconomic failures in public finances and competitiveness seem to originate the exceptional increases in sovereign spreads of the Periphery, through a contagion effect which is limited to this group of Eurozone countries.     

The fundamentals of sovereign debt sustainability: evidence from 15 OECD countries

We study the sustainability of sovereign debt accumulation in 15 OECD countries using quarterly data from 1980 to 2010 with a focus on how and in what countries debt sustainability changed after the commencement of the Euro Convergence Criteria in 1997 as well as after the financial meltdown in 2007. We define sustainability as the validity of the inter-temporal budget constraint of the government and test a sufficient condition motivated by Bohn (Q J Econ, 113(3):949–963, 1998) using single-country and pooled regressions. We find evidence that the Euro Convergence Criteria contributed to the sustainability of debt accumulation. Further, while the yield spreads suggest the debt crisis is a problem of the southern Euro countries, we find a lack of debt sustainability for Greece, Portugal and France but not for Italy and Spain. In terms of debt sustainability, the crisis adversely affected primarily stand-alone countries rather than members of the European Monetary Union. Nevertheless, yield spreads increased more in the southern countries of the monetary union than in stand-alone countries. Our results support the view that countries within a monetary union are more prone to investors’ sentiments than stand-alone countries.     

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.     

The effects of public deficits on money growth in the European Union

The impact of government debt on the money supply has been studied for different countries, with an emphasis on developing countries and the U.S. This topic becomes especially interesting in European Union countries that have high public deficits and low inflation rates. It is also very relevant in the monetary union, with a European central bank controlling monetary policy and introducing monetary measures for all the member countries. The main goal of this paper is to analyze if there is any relationship between public deficits and monetary growth in the European Union. The conclusions presented in the previous literature are ambiguous. Some studies concluded that there is little evidence that government debt influences money in some of the member countries.     

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.     

An Analysis of the Stability and Growth Pact

We use a stylised model to analyse the Stability and Growth Pact for countries that have formed the European Monetary Union (EMU). In our model, shortsighted governments fail to internalise the consequences of their debt policies for the common inflation rate fully. Therefore, while governments have no incentive to sign a stability pact in the absence of a monetary union, they do so with monetary union to restrain this externality. With uncertainty, a monetary union combined with an appropriately designed pact will be strictly preferred to autonomy. With differences in initial conditions, conflicts of interest arise. We study the Nash bargaining solution.     

A Political Economy Application of the “Tragedy of the Anticommons”: The Greek Government Debt Crisis

The tragedy of the anticommons unfolds when separate social agents—be they private owners of a property who intend to use the property for their own economic benefit or political actors who pursue their political objectives—do not hold effective rights to use their economic or political power for their own purposes without consent of the other players of the economic or political game. I shall discuss the Greek government debt crisis and the Eurozone countries’ policies toward Greece within the analytical framework of the tragedy of the anticommons in this paper. I do not intend to dig deep into the structure and long-term trends of public and private finances in Greece. I shall only show that the successive bail-out programs of the Eurozone countries were doomed to fail because of these countries’ competitive and non-cooperative approach to the Greek financial problems. I shall also show that a coordinating agency, say the IMF, can foster the coordinated outcome only under strict informational conditions.     

“Haircuts” for the EMU periphery: virtue or vice?

We use a dynamic game model of a two-country monetary union to study the impacts of an exogenous fall in aggregate demand, the resulting increase in public debt, and the consequences of a sovereign debt haircut for a member country or bloc of the union. Two different scenarios for such a haircut are assumed: an expected and an unexpected haircut. In the union, the governments of participating countries pursue national goals when deciding on fiscal policies whereas the common central bank’s monetary policy aims at union-wide objective variables. The union considered is asymmetric, consisting of a “core” with lower initial public debt, and a “periphery” with higher initial public debt. The “periphery’’ may experience the haircut due to the high level of its sovereign debt. We calculate numerical solutions of the dynamic game between the governments and the central bank using the OPTGAME algorithm. We show that a haircut as modeled in our study is disadvantageous for both the “core” and the “periphery” of the monetary union, both when expected and when unexpected.     

“Core” and “Periphery” in a Monetary Union: A Macroeconomic Policy Game

We develop a dynamic game model of a two-country monetary union to study strategic interactions between macroeconomic policy makers, namely the central bank and governments. In this union, the governments of participating countries pursue national goals when deciding on fiscal policies, whereas the common central bank’s monetary policy aims at union-wide objective variables. The union considered is asymmetric, consisting of a core, with lower initial public debt, and a periphery, with higher initial public debt. For a symmetric demand shock, we derive numerical solutions of the dynamic game between the governments and the central bank using the OPTGAME algorithm. We show that mildly active cooperative countercyclical policies dominate noncooperative solutions and a scenario of no policy intervention. Optimal policies call for a brief expansionary action to bolster the effects on output and a return to a small fiscal primary surplus as soon as the crisis is over until the targeted level of public debt is reached.     

Regional debt in monetary unions: Is it inflationary?

This paper studies the inflationary implications of interest bearing regional debt in a monetary union. Is this debt simply backed by future taxation with no inflationary consequences? Or will the circulation of region debt induce monetization by a central bank?We argue here that both outcomes can arise in equilibrium. In the model economy, there are multiple equilibria which reflect the perceptions of agents regarding the manner in which the debt obligations will be met. In one equilibrium, termed Ricardian, the future obligations are met with taxation by a regional government while in the other, termed Monetization, the central bank is induced to print money to finance the region's obligations. The multiplicity of equilibria reflects a commitment problem of the central bank. A key indicator of the selected equilibrium is the distribution of regional debt holdings. We show that regional governments, anticipating central bank financing of their debt obligations, have an incentive to create excessively large deficits. We use the model to assess the impact of some policy measures within a monetary union as well as dollarization.     

Re-Exploring the Enlargement of the Eurozone: Evidence from the New Member-States

The debt crisis of the Euro Area in 2010 raised plenty of doubts concerning the sustainability of the monetary union. Eurozone includes economies which have different structural characteristics. This event does not allow the establishment of an optimal currency area. The present research attempts to explore if the join of Cyprus, Malta, Latvia, Slovenia and Slovakia in the Eurozone was in favor of their economies. We used the nominal exchange rates as a financial instrument by combing the Error Correction Model with the Threshold GARCH, ECM-TGARCH. The empirical findings highly support that the EU membership influenced positively the relationship between the euro and the Cypriot Pound, the Latvian Lats and the Slovenian Tolar. On the contrary, we discovered that the join of Malta in the EU had a slightly negative and a long-term impact in the relationship between the euro and the Maltese currency. Finally, the entrance of Slovakia in the EU influenced positively the Slovakian currency. However, the relationship between the euro and the Slovakian Koruna remained negative.     

Monetary Policy Coordination and the Level of National Debt

This paper uses the Canzoneri-Henderson benchmark framework of monetary policy coordination in interdependent economies to analyze how high levels of national debt affect monetary policy interactions. Using a two-country model, I first study how central banks interact in a flexible exchange-rate regime. I find that a low-debt country is better off interacting with a country with high debt, when both economies are affected by an aggregate inflationary shock. I also consider a political dependence scenario, in which central banks are subject to political pressure. In the case of a debt-burdened country, the political incentive to reduce interest payments on debt will spur a Gordon–Barro like inflation bias. However, under a flexible exchange-rate regime, the low-debt country will not be affected. Under a monetary union instead, political pressure may affect the low-debt country as well, and possibly create an inflation bias even greaterthan in the flexible exchange-rate regime. This scenario presents another example of how Rogoff's counterproductive monetary cooperation may arise under European Monetary Union.     

Discretionary policy in a monetary union with sovereign debt

This paper examines the interactions between multiple national fiscal policymakers and a single monetary policy maker in response to shocks to government debt in some or all of the countries of a monetary union. We assume that national governments respond to excess debt in an optimal manner, but that they do not have access to a commitment technology. This implies that national fiscal policy gradually reduces debt: the lack of a commitment technology precludes a random walk in steady-state debt, but the need to maintain national competitiveness avoids excessively rapid debt reduction. If the central bank can commit, it adjusts its policies only slightly in response to higher debt, allowing national fiscal policy to undertake most of the adjustment. However, if it cannot commit, then optimal monetary policy involves using interest rates to rapidly reduce debt, with significant welfare costs. We show that in these circumstances the central bank would do better to ignore national fiscal policies in formulating its policy.     

Law in Modern Society

In this article, we study the relationship between monetary policy and the socio-institutional framework. Specifically, we examine the economic policy response to the debt crisis of the Eurozone, applying institutional economics from two perspectives: the theory of social power and the endogenous money supply. The research question is whether monetary policy can be characterized as a countervailing power exercised by European institutions with respect to the member countries. Fiscal and monetary policies have been interpreted through these sources and types of power, as proposed by Galbraith, by distinguishing between those types of power that have had a permanent versus a conjunctural character. We conclude that European Quantitative Easing can be characterized as having been a countervailing power. All of this has strengthened European institutional power despite having been manifested in the context of an economic and financial crisis.     

The Euro at ten: achievements and challenges

In this paper we discuss the achievements and the challenges of the Eurozone. We first analyze the record with respect to inflation. Second, we discuss the degree of price transparency in the Eurozone. Next we analyze the extent to which monetary union has promoted faster economic growth. Fourth, we study the challenges that arise from the increasing divergencies of wages and prices within the Eurozone. We conclude with a discussion of the governance of the Eurozone and the political issues to which this leads.     

A simulation study of an ASEAN monetary union

This paper analyzes some pros and cons of a monetary union for the ASEAN¹ countries, excluding Myanmar. We estimate a stylized open-economy dynamic general equilibrium model for the ASEAN countries. Using the framework of linear quadratic differential games, we contrast the potential gains or losses for these countries due to economic shocks, in case they maintain their status-quo, they coordinate their monetary and/or fiscal policies, or form a monetary union. Assuming for all players open-loop information, we conclude that there are substantial gains from cooperation of monetary authorities. We also find that whether a monetary union improves upon monetary cooperation depends on the type of shocks and the extent of fiscal policy cooperation. Results are based both on a theoretical study of the structure of the estimated model and a simulation study.

On the Role of Labour Market Reform for the Enlargement of a Monetary Union

This paper studies the incentives to join a monetary union,and the incentives to reform within a monetary union and withinthe candidate countries, respectively. We present some "ordersof magnitude" evidence on the size and balance of the incentiveeffects for joining and being joined, and on the desirabilityof reform in and out of the existing EMU in Europe. It is foundthat countries will only want to join a monetary union wherethere has been sufficient labour market reform, and where labourmarkets are more flexible than their own. But existing memberswill want the same properties of their new partners as well.(JEL F02, F15, F33, F 42)
