Changes in behaviour under EMU

Using a simple model of the euro area economy, we explore whether EMU has been associated with changes in behaviour both in the run up to Stage 3 and since it started operating. We find that some behaviour has indeed changed; expectations formation, inflation, country dispersion of behaviour, fiscal policy (although the run up to Stage 3 shows a greater change than within it) and monetary policy (with several caveats). However, EMU does not appear to be associated with changes in the labour markets; employment, output growth and productivity. Substantial caution is needed in attributing these changes to EMU as much of the rest of OECD enjoyed similar changes over the same period.     

Does the Lucas critique apply during hyperinflation?: empirical evidence from four hyperinflationary episodes

Farmer (Review of Economic Studies, 58, 321–32, 1991) suggests that in a model in which there are multiple rational expectations equilibria agents may find it useful to coordinate their expectations in a unique rational expectations equilibrium which is supported by a self-fulfilling forecast rule having the property of being immune to the Lucas Critique. In this paper, Farmer's hypothesis is tested using data from hyperinflationary episodes. It is believed that those episodes are suitable for testing this hypothesis because an agent who lives in a hyperinflationary environment usually faces frequent changes in policy regime. The agent may thus choose a selffulfilling forecast rule which is immune to the Lucas Critique as a way of hedging against unanticipated policy regime switches. The empirical results show mixed evidence on Farmer's hypothesis during the hyperinflationary episodes studied.     

DOES THE ECB HAVE A TIME‐INCONSISTENCY PROBLEM? A NOTE

A standard time‐inconsistency model of monetary policy, extended to include a time‐varying natural rate of unemployment, implies cointegration between the inflation rate and the unemployment rate. An application of the model to data for the EMU countries does not yield strong evidence of cointegration. In addition, the sign of the estimated coefficient of cointegration is not in line with a sign restriction imposed by the time‐inconsistency model.     

Does the Euro follow the German Mark? Evidence from the monetary model of the exchange rate

This paper investigates whether German or synthetic European pre-EMU data provides the appropriate empirical basis for evaluating Euro/Dollar exchange rate behavior. Monetary exchange rate equations are estimated for both data sets over the pre-EMU period, and out-of-sample forecasts are evaluated to assess their ability to explain the Euro/Dollar exchange rate from 1999 to 2004. While forecast accuracy tests confirm the usefulness of synthetic European data for Euro exchange rate analysis, forecasts based on the German pre-EMU experience cannot even beat a random walk. Our results indicate that the Euro does not simply follow the German Mark, but that it has its origins in the other pre-EMU currencies as well.     

In or out? The welfare costs of EMU membership

Sweden and the UK have repeatedly refused to join the European and Monetary Union (EMU). Surprisingly, there is very little work on the welfare consequences of the loss of monetary policy flexibility for these countries. This paper fills this void by providing a framework to evaluate quantitatively the economic costs of joining the EMU. Using a two-country dynamic general equilibrium model with sticky prices we investigate the economic implications of the loss of monetary policy flexibility associated with the EMU for each country. The main contribution of our general equilibrium approach is that we can evaluate the effects of monetary policy in terms of welfare. Our findings suggest that these economies may experience sizable welfare losses as a result of joining the EMU. Results show that the cost associated with the loss of the monetary policy flexibility is higher in the presence of persistent government consumption shocks and small trade shares with the EMU.     

Do real exchange rates really follow threshold autoregressive or exponential smooth transition autoregressive models?

Nonlinear models, especially threshold autoregressive [TAR] and exponential smooth transition autoregressive [ESTAR] classes, are widely applied for modeling real exchange rates in order to examine the validity of purchasing power parity [PPP]. Even though the nonlinear models are theoretically well-motivated, some of the recent findings cast doubts on their relevance for real exchange rates. In particular, the nonlinear models do not necessarily yield improved out-of-sample forecasts over linear models and add little value in resolving the well-documented PPP puzzle. Utilizing a nonparametric entropy measure of dependence proposed by Granger et al. (2004), we show, in this study, that the real exchange rates from four major countries had exhibited quite strong nonlinear serial dependence, which linear autoregressive models fail to replicate. Furthermore, the nonlinear TAR and ESTAR models estimated for the real exchange rates also have some difficulty in generating significant serial dependence structure actually observed in the data. Overall, other nonlinear models than the currently entertained TAR and ESTAR should be considered to study the dynamics of the real exchange rates.     

What drives international financial flows? Politics,institutions and other determinants

This paper uses a large panel of financial flow data from banks to assess how institutions affect international lending. First, employing a time varying composite institutional quality index in a fixed-effects framework, the paper shows that institutional improvements are followed by significant increases in international finance. Second, cross-sectional models also show a strong effect of initial levels of institutional quality on future bank lending. Third, instrumental variable estimates further show that the historically predetermined component of institutional development is also a significant correlate of international bank inflows. The results thus suggest that institutional underdeveloped can explain a significant part of Lucas [Lucas, Robert E. 1990. “Why Doesn't Capital Flow from Rich to Poor Countries?” American Economic Review (Papers and Proceedings), 80 (2): 92–96. 1990] paradox of why doesn't capital flow from rich to poor countries. The analysis also does a first-step towards understanding which institutional features affect international banking.     

Does the Single Currency Affect Foreign Direct Investment?*

Does the creation of the euro partly explain the sharp increase in European investments? To address this question, we derive a simple gravity‐like model for bilateral foreign direct investment (FDI). Using this model, we find that the Economic and Monetary Union (EMU) has increased intra‐EMU FDI stocks on average by around 30 percent. This effect varies over time and across EMU members. It is found to be larger for the outward investments of the less‐developed EMU members. Moreover, contrary to early expectations of FDI diversion effects, EMU countries have invested more in non‐EMU countries since the launch of the euro.     

How far from the Euro Area? Measuring convergence of inflation rates in Eastern Europe

We present a common factor framework of convergence which we implement using principal components analysis. We apply this technique to a dataset of monthly inflation rates of EMU and the Eastern European New Member Countries (NMC) over 1996–2007. In the earlier years, the NMC rates moved independently from an average of the three best performing countries over the past twelve months, while they moved somewhat closer in line with them in the later years. Looking at the sample of the EMU and NMC countries as a whole, there is evidence of a formation of convergence clubs across the two groups.     

The Credibility Problem Revisited: Thirty Years on from Kydland and Prescott*

Macroeconomics research has changed profoundly since the Kydland–Prescott seminal paper. In order to address the Lucas Critique, modeling is now based on micro‐foundations treating agents as rational utility optimizers. Bayesian estimation has produced models which are more data‐consistent than those based simply on calibration. With micro‐foundations and new linear‐quadratic techniques, normative policy based on welfare analysis is now possible. In the open economy, policy involves a “game” with policymakers and private institutions or private individuals as players. This paper attempts to reassess the Kydland–Prescott contribution in the light of these developments.     

MONEY DEMAND STABILITY AND INFLATION PREDICTION IN THE FOUR LARGEST EMU COUNTRIES

In this paper, we analyze the money demand functions of the four largest EMU countries and of the four-country (EMU-4) aggregate. We identify reasonable and stable money demand relationships for Germany, France and Spain as well as the EMU-4 aggregate. For the case of Italy, results are less clear. From the estimated money demand functions, we derive both EMU-4 and country-specific measures of money overhang. We find that the EMU-4 overhang measure strongly correlates with the country-specific measures, particularly since the start of EMU, and is useful to predict country-specific inflation. However, it generally does not encompass country-specific money overhang measures as predictors of inflation. Hence, aggregate money overhang is an important, but by far not an exhaustive, indicator for the disaggregate level.     

Has the Euro changed the business cycle?

In contrast to the notion that the exchange-rate regime is non-neutral, there is little evidence that EMU has systematically changed the European business cycle. In fact, we find the volatility of macroeconomic variables largely unchanged before and after the introduction of the Euro. Exceptions are a strong decline in real exchange rate volatility and a considerable increase in cross-country correlations. To account for this finding, we develop a two-country business cycle model which is able to replicate key features of European data. In particular, the model correctly predicts a limited effect of EMU on standard business cycles statistics. However, further analysis reveals that the Euro has changed the nature of the cycle through its impact on the transmission mechanism. Cross-country spillovers have become relatively more, domestic shocks relatively less important in accounting for economic fluctuations under EMU. This explains why there is little change in unconditional volatilities.     

Self-confirming equilibrium and the Lucas critique

We examine the role of off-path “superstitions” in macro-economics, and show how a false belief about off-path play is the key element underlying both the Lucas Critique and the game-theoretic concept of self-confirming equilibrium. However, the impact of false beliefs in these two cases is different: In the Lucas case, a policy maker's incorrect beliefs about off-path play can lead to the adoption of mistaken policy innovation. However, the consequences of such an innovation provide evidence that the belief that motivated them was wrong. In contrast, play may never escape an undesirable self-confirming equilibrium, as the action implied by the mistaken belief does not generate data that contradicts it; escape from the self-confirming equilibrium requires that players do a sufficient amount of experimentation with off-path actions.     

Revisiting the effects of regional trade agreements on trade flows with proper specification of the gravity model

This paper uses a gravity model to assess ex-post regional trade agreements. The model includes 130 countries and is estimated with panel data over the period 1962-1996. The introduction of the correct number of dummy variables allows for identification of Vinerian trade creation and trade diversion effects, while the estimation method takes into account the unobservable characteristics of each pairs of trade partner countries, the endogeneity of some of the explanatory variables as well as a potential selection bias. In contrast to previous estimates, results show that regional agreements have generated a significant increase in trade between members, often at the expense of the rest of the world.     

Estimating A European Demand For Money

European Monetary Union will come into existence in 1999. This raises questions related to the monetary policy targets that will be adopted by the European Central Bank (ECB). For both likely candidates, targeting a money aggregate or an inflation target, the existence of a stable money demand function at a European level is important. In this paper estimates of such a European money demand for narrow and broad money for the actual 11 EMU countries based on quarterly aggregate data from 1964 to 1994 are presented. It is argued that statistically satisfactory and economically interpretable functions can be found. Moreover, the estimated models appear to be stable over a period of 20 quarters. This raises the hopes that the ECB will face a stable money demand and be able—at least for a certain time—to use past aggregate data for policy purposes.     

Monetary and Fiscal Policy Rules in the EMU

Abstract. This paper studies the design and effects of monetary and fiscal policy in the euro area. To do so, a stylized two‐region model of monetary and fiscal policy rules in the EMU is built. We analyse how monetary and fiscal rules affect the adjustment dynamics in the model. Both the effects on the individual countries and on the EMU aggregate economy are studied. Three aspects play an important role in the analysis: (i) the consequences of alternative monetary and fiscal policy rules, (ii) the consequences of asymmetries between EMU countries (asymmetries in macroeconomic shocks and macroeconomic structures), and (iii) the role of alternative degrees of backward‐ and forward‐looking behaviour in consumer decisions and inflation expectations.     

Aid, policy and growth in post-conflict societies

Countries emerging from civil war attract both aid and policy advice. This paper provides the first systematic empirical analysis of aid and policy reform in the post-conflict growth process. It is based on a comprehensive data set of large civil wars, and covers 17 societies that were in their first decade of post-conflict economic recovery. We first investigate whether the absorptive capacity for aid is systematically different in post-conflict countries. We find that during the first 3 post-conflict years absorptive capacity is no greater than normal, but that in the rest of the first decade it is approximately double its normal level. Thus, ideally, aid should phase in during the decade. Historically, aid has not, on average, been higher in post-conflict societies, and indeed it has tended to taper out over the course of the decade. We then investigate whether the contribution of policy to growth is systematically different in post-conflict countries, and in particular, whether particular components of policy are differentially important. For this we use the World Bank policy rating database. We find that growth is more sensitive to policy in post-conflict societies. Comparing the efficacy of different policies, we find that social policies are differentially important relative to macroeconomic policies. However, historically, this does not appear to have been how policy reform has been prioritized in post-conflict societies.     

Structural breaks in the lending interest rate pass-through and the euro

This paper investigates whether size and speed of the pass-through of market rates into short term business lending rates have increased in the wake of the introduction of the euro. Allowing for multiple unknown structural breaks we find two in four EMU countries, and in the UK as well, and a single one in five other countries. The pattern of dates fits national banking systems adjusting slowly to the new monetary regime and suggests caution in associating structural changes to the introduction of the euro. The estimated equilibrium pass-through in the last break-free period is on average more incomplete, hinting at a reduced effectiveness of the single monetary policy. These results run against the economic intuition that a reduced volatility in money market rates is bound to mitigate uncertainty and to ease therefore the transfer of policy rate changes to retail rates; the run-up to Basel 2 and a deterioration of competition in loan markets could be the motivations. Caution in extrapolating these findings to recent periods is suggested by the differences between the unharmonized and the new harmonized retail rates.     

Structural change in the yellow fats market

The superexogeneity of wage equations is tested in four major European countries. This is an important issue because while only weak exogeneity is needed for estimation purposes and for testing, and strong exogeneity for forecasting, superexogeneity is required for policy analysis. The procedure suggested by Engle and Hendry (1993) is adopted to carry out the empirical analysis. In all cases the conditional model is not affected by the first and second moments of the residuals from the marginal models. This invariance result implies that the estimated linear regression models are not subject to the Lucas critique over the period examined. Differences in wage determination between the various countries can be plausibly interpreted as resulting from the bargaining environment.     

A copula-VAR-X approach for industrial production modelling and forecasting

World economies, and especially European ones, have become strongly interconnected in the last decade and a joint modelling is required. We propose here the use of copulae to build flexible multivariate distributions, since they allow for a rich dependence structure and more flexible marginal distributions that better fit the features of empirical data, such as leptokurtosis. We use our approach to forecast industrial production series in the core European Monetary Union (EMU) countries and we provide evidence that the copula-Vector Autoregression (VAR) model outperforms or at worst compares similarly to normal VAR models, keeping the same computational tractability of the latter approach.
