Thoughts on a Fiscal Union in EMU

Using an estimated large‐scale New Keynesian model, we assess the consequences of introducing a fiscal union within EMU. We differentiate between three different scenarios: public revenue equalisation, tax harmonisation and a centralised fiscal authority. Our results indicate that no country would significantly benefit from introducing any form of fiscal union. Comparing long‐term, that is, steady state, effects we have winners and losers depending on the scenario. Differences in terms of business cycle statistics as well as in terms of risk sharing of asymmetric shocks are minor. This also explains why welfare differences are small across the fiscal union scenarios. A counterfactual exercise indicates that with a fiscal union regime already installed at the start of EMU, key macroeconomic variables would have reacted very similarly while debt dynamics would have changed notably.     

The Minimum Economic Dividend for Joining a Currency Union

A two‐country model is developed to show how the optimality of a currency union depends on whether it brings an economic dividend in terms of potential growth and the Balassa–Samuelson (BS) effect (the steady appreciation of the real exchange rate due to cross‐country differences in intersectoral productivity gaps). The model shows that such dividend needs to be larger, the higher the BS effect, the smaller the size of the economy, the larger the cross‐country difference in the standard deviation of the supply shocks, the smaller their correlation and the larger the standard deviation of real exchange rate shocks. We calibrate the model to quantify such dividend as a function of plausible ranges of the parameter values. The results suggest that both the BS effect and the size of real exchange rate shocks play a key role in evaluating the optimality of accessing the currency union.     

Fiscal Austerity and the Multiplier in Times of Crisis

To address concerns about the sustainability of public debt, most industrialized countries shifted towards fiscal austerity after 2010. A popular concern is that austerity is self‐defeating, because fiscal multipliers can be large. Specifically, a number of recent studies find that multipliers tend to be large during financial crises and/or if monetary policy is constrained by the zero lower bound. However, public debt crises tend to have an offsetting effect by making multipliers smaller than during normal times. Consequently, while austerity is no cure for all, it is unlikely to be literally self‐defeating when sovereign risk is high.     

Asymmetric Shocks and Monetary Policy in a Currency Union

We analyze the conduct of monetary policy in a currency union in the face of asymmetric shocks. In particular, we compare the stabilization properties of a currency union versus alternative exchange rate arrangements. The relative performance of a currency union is shown to depend on the extent of economic integration in patterns of consumption and production and on the relative weights placed on price stability versus employment stability in the monetary authority's objective function.

Do Monetary Unions Make Economic Sense? Evidence from the Scandinavian Currency Union, 1873–1913

Popular propositions as to what constitutes a successful single currency area are examined by looking at the Scandinavian Currency Union (1873–1913) formed by Denmark, Norway and Sweden. Applying a frequently used indicator of the desirability of monetary union, we study the symmetry of country-specific structural shocks (measured net of the non-Scandinavian influence) in these three countries. It is found that country-specific shocks are not highly symmetric. This conclusion is also supported by the absence of clear-cut differences between the pattern of structural shocks in Belgium and structural shocks in the Scandinavian countries. This suggests that the three Scandinavian countries did not form an optimum currency area during the period 1873–1913.

Fiscal Institutions and Wage Bargaining in the Local Public Sector

In a theoretical analysis of the properties of different wage setting and financing systems in the local public sector, two financing systems are considered. A benchmark model with local financing through local taxes is compared with a system of centralized financing through grants, where taxes are decided at the national level. It is shown that the wage outcomes under centralized financing depend heavily on the order of moves in the budgetary game between the central and local levels.

Rating Agencies – An Experimental Analysis of Their Remuneration Model

Does it matter who pays for ratings? Yes, but not for the rating agencies’ behavior. These are the findings of our experiment where we analyze the effect of the remuneration model of rating agencies on their assessments as well as on investors’ and issuers’ behavior. First, we find that rating agencies’ assessments are comparable whether the agency is (partially) paid by issuers, investors or solely by the experimenter. Issuers, on the other hand, more often do not return investor's trust when they or investors pay for ratings. Further, investors more often act according to the agencies’ recommendations when they have to pay for this information.     

The Endogeneity of Optimum Currency Areas Criteria: Some Evidence from the European Union and Portugal

Observing the statistical relationship between business cycles correlation and trade intensity in the European Union, euro zone, and the Portuguese economy, we conclude that there is, in general, a positive effect that supports the endogeneity argument proposed by Frankel and Rose (The Economic Journal 108(449):pp. 1009–1025, 1998). However, if we analyse this relationship in sub-periods – 1967–1975, 1976–1985, 1986–1992, and 1993–2003 – we conclude that endogeneity hypothesis just hold in the first two, although the correlations are increasing. This could mean that, after the Single European Act in 1986, other forces beyond trade are contributing to business cycle synchronization. The Portuguese business cycle correlation with the European Union and the Euro zone had also increased in these four decades, despite the fact that endogeneity hypothesis is at a 90 percent confidence level. We also analyse the bilateral relationships between the Portuguese economy and the other European Union countries and find that the endogeneity is confirmed in just four cases: Spain, Ireland, Netherlands, and UK.     

Stabilizations, crises and the “exit” problem – A theoretical model

Exchange-rate-based stabilizations, even if successful, usually lack credibility initially. This is reflected in high (ex post) real interest rates and some degree of real exchange rate appreciation. Empirical observation suggests that wage inflation declines smoothly over time whilst interest rates are volatile. Our model captures these features and provides insights into: the eruption of exchange rate crises after a long period of apparently successful stabilization; the potential advantages of a heterodox approach; when to delay a stabilization attempt; and the optimal date for “exit” to a floating exchange rate.     

Monetary integration in the ex‐Soviet Union: A ‘union of four’?*

The governments of four ex‐Soviet countries recently discussed forming a currency union. To examine the economic feasibility of this proposition, we use conventional techniques and show that the arrangement is likely to find it difficult to handle the lack of structural symmetry, the asymmetric pattern of shocks, and the lack of market flexibility among the potential participants. Moreover, the union would be a unilateral one. It would require an unusual degree of political commitment to survive. Nonetheless, there are some subtleties in the timing and pattern of mutual dependence between Russia and Kazakhstan, and to a lesser extent in Belarus, which may reduce the strain from a currency union in those countries. Otherwise, the black market will have to provide the necessary market flexibility.     

Fairness Considerations in Labor Union Wage Setting – A Theoretical Analysis

We consider a theoretical model in which unions not only take the outside option into account, but also care about the performance of the firm and base their wage‐setting decisions on a firm internal reference, called the fairness reference. Two references, which measure the earnings situation of the firm, are considered – productivity and profits per worker. Wage and employment outcomes as well as the degree of wage rigidity depend on the size of the fairness reference relative to the outside option. A high fairness reference leads to wage pressure and real wage rigidity, whereas a low fairness reference leads to wage moderation and real wage flexibility. An increase in the weight on the fairness reference amplifies these deviations from the standard model.     

Controlled Dismantlement of the Eurozone: A Strategy to Save the European Union and the Single European Market

The problems with a single currency in Europe are neither temporary nor curable. Any persistent defence of the euro will result in a long‐lasting recession and high unemployment in countries using fiscal austerity to pursue ‘internal devaluation’. It may lead to a revival of populist and nationalist movements, political collapse and disorderly eurozone break‐up. This article argues for a controlled segmentation of the eurozone via the exit of the most competitive countries and an agreement on a new European currency coordination system.     

Fiscal policy,macroeconomic performance and industry structure in a small open economy

We analyse how fiscal policy affects both the macroeconomy and the industry structure, using a multi-sector macroeconomic model of the Norwegian economy with an inflation targeting monetary policy. Our simulations show that the magnitude of the government spending and labour tax cut multipliers, whether monetary policy is active or passive, is comparable to what is found in the literature. A novel finding from our simulations is that the industry structure is substantially affected by an expansionary fiscal policy, as value added in the non-traded goods sector increases at the expense of value added in the traded goods sector. Moreover, expansionary fiscal policy reduces the mark-ups in the traded goods sector, while the mark-ups are roughly unchanged in the non-traded goods sector. The contraction of activity in the traded goods sector increases when monetary tightening accompanies the fiscal stimulus. Hence, we find that such a policy mix is likely to produce significant de-industrialization in a small open economy with inflation targeting.     

Macroeconomic Performance and Wage Bargaining in a Monetary Union

Building on a micro-founded model of a two-region monetary union, this paperanalyses the macroeconomic impact of institutional reforms in labour marketsand central banking that may occur as a result of monetary unification. Thepaper shows that monopoly distortions in the labour market are a key factorin evaluating the effects of central bank's conservativeness and wagecentralisation on inflation and unemployment. Wage restraint is favoured ina highly decentralised wage bargaining setup as well as under a liberalcentral bank, provided competition is high in the labour market.     

Entry and fiscal policy effectiveness in a small open economy within a Monetary Union

In this article I develop an imperfectly competitive dynamic general equilibrium model for a small open economy integrated in a monetary union. Here, the type of entry in the non-traded goods’ sector affects fiscal policy effectiveness. Fiscal policy effectiveness is enlarged when aggregate demand stimuli increase intra-industrial competition (case I). This is due to the counter-cyclical mark-up mechanism generated by entry. Such a mechanism is absent in the usual monopolistic competition where entry only has a sharing effect (case II).

Tax Base and Crowding‐in Effects of Balanced Budget Fiscal Policy

A dynamic general equilibrium business cycle model is constructed with staggered price adjustment, monopolistic wage setting and distortionary taxation. The government purchases goods, runs an unemployment benefit system and balances its budget through a proportional tax on labour income. A temporary tax‐financed increase in government expenditures can lower the tax rate through a demand‐induced widening of the tax base. It is shown analytically that this allows private consumption to rise, under realistic conditions, despite the negative wealth effect of increased fiscal spending.     

Synchronization and diversity in business cycles: a network analysis of the European Union

In this article, we use a correlation matrix and its internal networks to analyse business cycle synchronization across Europe since 2000. This methodology allows us to summarize individual country interactions and co-movements while also capturing the existing heterogeneity of connectivity within the European economic system. Our results indicate that synchronization of the euro zone countries remained stable from 1999 until the current financial crisis, after which co-movements increased sharply and synchronization rose to the highest in the time sample. By endogenously identifying clusters of countries with close connections in their business cycle, we also refute the commonly accepted notion of identifiable core and peripheral euro zone countries.     

Anatomy of a balance-of-payments crisis : Application of a computable general equilibrium model to Turkey, 1978–1980

This paper analyses quantitatively the causes of the foreign exchange crisis in Turkey in the late 1970s through application of a multisector computable general equilibrium (CGE) model. The model incorporates some mechanisms that simulate the actual workings of the foreign exchange market during the turbulent foreign exchange disequilibrium period 1978–1980. It features the simultaneous operation of both quantitative controls and premium rationing schemes. Factors contributing to the foreign exchange crisis are analysed through counterfactual simulations which examine the implications for the Turkish economy of use of a flexible exchange rate, no oil price shock in the 1978–1980 period, and maintaining a constant price-level deflated affective exchange rate. Our results indicate that while exchange rate policy played an important role in bringing about the foreign exchange crisis, the influence of other factors was substancial.
