Which Single Currency for Western Europe?

The Maastricht Treaty calls for a single European money in the third and final stage of European monetary integration. The purpose of this paper is to infer the preferred currency from the point of view of economic agents in each EMS country by ranking the realized distributions of returns from holding foreign currencies. These rankings are obtained using the notion of generalized stochastic dominance. The preferred currency varies with time and the portfolio considered. In all cases, the ECU is not supported as a likely dominant money.     

Multiple Wage Bargaining Systems in the Single European Currency Area

Little attention in the EMU literature has been paid to the interaction between centralbank monetary rules and systems of collective wage bargaining. Analytically andempirically, coordinated wage bargaining systems respond with real wage restraintto non-accommodating monetary policy. Since wage determination is dominated bycollective bargaining in all the EMU member states and wage coordination within themember states has grown since 1980, this is a topic of potential importance. In particular, the replacement of the Bundesbank, directly targeting German inflation, by an ECB targeting European inflation has removed a major institutional support of wage restraint in Germany. The consequences of this for EMU are worked out under two scenarios, that inflation expectations will be generated by ECB monetary policy and that they will reflect German inflation outcomes. Possible institutional developments are discussed including government-union bargains. The Bundesbank has also played a major role in maintaining fiscal rectitude by targeting excess fiscal deficits in Germany: again its replacement by the ECB – targeting (if at all) European rather than German fiscal policy – loosens fiscal constraints. For underlying structural reasons therefore, it is possible that Germany and other EMU countries will move to a period of fiscal activism with wage restraint and low inflation purchased through social contract negotiations.     

Exports and Indirect Hedging of Foreign Currency Risk

We present a model of a risk-averse competitive exporting firm under exchange rate risk. Direct hedging instruments are not available. However, there are domestic assets whose prices are correlated to the foreign currency. We consider a market for futures contracts in these domestic assets and investigate the firm's indirect hedging and export policy. It is shown that the availability of many financial instruments correlated with foreign exchange may, under some circumstances, provide the same results as a perfect hedge.

欧洲中央银行统一货币政策的内外制约与协调改进

欧洲央行的统一货币政策实施中在维持物价稳定、促进经济增长等方面起到了一定的作用 ,但在运行中也暴露出了央行责任弱化、决策过程忽略整体利益、货币政策战略目标互相冲突等政策机制的内在缺陷 ;同时 ,也存在货币政策难以达到统一、有效的目标、欧元区成员国相对独立的财政政策与统一的货币政策难以协调等外在制约。因此 ,欧洲中央银行需通过强化非正式的责任义务、保持决策的公开性、建立经济与政治各领域新的制衡机制、处罚机制、调整货币政策战略、统一协调财政政策等措施来改进货币政策。     

West African Single Currency and Competitiveness

This paper compares different nominal anchors to promote internal and external competitiveness in the case of a fixed exchange rate regime for the future single regional currency of the Economic Community of the West African States (ECOWAS). We use counterfactual analyses and estimate a model of dependent economy for small commodity exporting countries. We consider four foreign anchor currencies: the US dollar, the euro, the yen and the yuan. Our simulations show little support for a dominant peg in the ECOWAS area if they pursue several goals: maximizing the export revenues, minimizing their variability, stabilizing them and minimizing the real exchange rate misalignments from the fundamental value.     

Single Beta Models and Currency Futures Prices

The conditional capital asset pricing model is applied to foreign currency futures prices, covariance risk being measured relative to excess returns from a broadly diversified international portfolio of equities. Positive time-varying risk premia are found in all five currencies tested when the difference between the US and the average foreign interest rates is used as an instrumental variable for the expected excess return from the common stock portfolio.     

The Single Market and Geographic Concentration in Europe

The stylized fact that regional concentration is lower in Europe than in the USA has led to the prediction that the creation of the Single Market might increase spatial concentration in Europe. This has raised some fears that the social and political burden of rapid change might counterbalance the economic gains, that the core might win to the detriment of the periphery, and that concentration of industry might make countries more vulnerable to asymmetric shocks in the Monetary Union. This paper uses a new disaggregated dataset to substantiate whether spatial concentration increased during the 1990s. Most other studies have not extended beyond the early 1990s or have used less comprehensive and detailed datasets. The main result is that geographic concentration did not increase, but rather decreased during the 1990s. Industrial patterns of geographic concentration and its dynamics partly conformed to the hypotheses provided by economic geography, trade theory, and industrial organization.     

The Single Currency and Labour Market Flexibility: a Necessary Partnership?

This paper examines the macroeconomic consequences of rigidities in the European labour markets, and shows that attempts to impose a single monetary regime on economies with different structures can lead to a breakdown in co-ordination. Such breakdowns can occur when expenditure-switching effects are dominated by the income effects of greater policy discipline. Market flexibility should therefore be given greater importance than the process of policy formulation in the 'New Europe'     

The impact of West European trade strategies on exports to Eastern Europe

This paper examines the extent to which West European countries have utilized diplomacy and reductions in trade barriers to improve their export performance in East European markets during the 1960's. Equal-price export shares of 7 West European countries are estimated by means of an econometric model, and their behavior over time and among importing regions is related to the commercial and foreign policies of the exporters. Our results demonstrate that East European import decisions have been significantly influenced both by changes in western commercial policies and by diplomatic initiatives such as DeGaulle's effort at détente with the Soviet Union. Our results also indicate that elasticities of substitution in East-West trade are significantly lower than those in trade among western countries.

A sequential approach to regional integration: The European Union and Central and Eastern Europe

This paper develops a theory of optimal sequencing of regional integration and applies it to the specific question of Central and Eastern European countries (CEECs) and the EU. We show that the timing of transition and integration has implications for the long-term trade structure of Europe. In this model the interest to integrate the CEECs comes from harmonization of policies to attract industries. Without integration, European countries will try to inefficiently protect their industries. Because of the transfers implied by the CAP and the Structural Policies, the EU delays enlargement until the CEECs have sufficiently converged. CEECs might at this point prefer to stay outside the EU and attract industries by offering them more generous protection than the EU. Such timing may be inefficient ex ante for all countries because it may prevent full European integration in the long run, inducing firms to relocate outside of the EU and governments in the EU and the CEECs to inefficiently protect industry. During the transition, all countries benefit from regional integration among the CEECs.     

The competition effects of the Single Market in Europe

The reduction in trade barriers in Europe through the Single Market Programme (SMP) was intended to increase competition in European markets, and hence welfare and efficiency. The paper examines how the SMP has affected trade patterns and what can be learnt from this regarding the impact on competitive behaviour. Combining an econometric and computable general equilibrium methodology, it is argued that (1) the SMP has indeed had a strong impact on competitive behaviour; (2) the extent of the impact depends both on changes in the intensity of competition as well as on changes in the nature of competitive interaction; (3) while all economies experience potentially large welfare gains from the SMP, it is the smaller economies that experience the larger gains, but this in turn suggests that they experience a greater degree of restructuring.     

从国家货币到市场货币 --货币与国家关系的解读

本文以货币与国家的历史联系为线索，通过分析国家货币垄断状态下二者的相互作用，说明市场货币是货币与国家协调过程中为适应新环境出现的一种新现象，金融全球化并未从根本上改变国家货币主权。国家货币产生于与民族国家发展相关的历史过程，一旦发展成熟与完善，又反过来增强民族国家的政治特征。货币既产生于民族国家的政治经济诉求，又必将服务于此，这是历史与现实相互作用的结果。     

Exports and economic growth in Central and East European countries during transition

This paper quantifies the contribution of exports to economic growth in Central and East European countries (CEECs) during transition. Two theoretical models are examined: the first is based on an aggregate production function which includes exports as an additional ‘input’; while the second is based on a two-sector (exports and non-exports) model where exports provide positive externalities in non-export production. Each model is estimated with both fixed and random effects using panel data. Results show that the random effects model is preferred and that exports have a significant impact on economic growth.

Monetary Union and the Transaction Cost Savings of a Single Currency

This paper computes the transaction cost savings derived from the European Monetary Union. A continuoustime, stochastic, Baumol-like model is generalized to include several currencies and calibrated to fit European data. The analysis implies an upper bound for the savings derived from reductions in transaction costs of approximately 0.69% of Union GDP. Additionally, the magnitudes of the brokerage fee and the volatility of transactions, whose estimation has traditionally been difficult to address empirically, are approximated for Europe.     

Mundell Revisited: a Simple Approach to the Costs and Benefits of a Single Currency Area

The paper evaluates the costs and benefits of a single currency area within a unified framework. Conventionally, it is argued that a single currency area carries a welfare loss owing to the sacrifice of exchange rate adjustment in the presence of country‐specific shocks. But in 1973 Mundell argued that a single currency area offers risk‐sharing benefits when capital markets are limited in their ability to facilitate consumption insurance. The authors construct a simple model and compare a system of independent national currencies to a single currency area. The presence of country‐specific shocks may either reduce or enhance the benefits of a single currency area, depending on the importance of exchange rate adjustment relative to risk‐sharing. In a simple quantitative analysis, we find that either regime may dominate, although the utility differences between the two regimes are very small.     

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.
