Testing for convergence of the Okun’s Law coefficient in Europe

Without convergence of macroeconomic parameters representative of the nature of adjustment mechanisms, even a common shock to members of a monetary union can lead to different macroeconomic consequences across the union and, eventually, to the need for more or less co-ordinated specific policies. In this paper, we test for the presence of convergence of the Okun’s Law coefficient (OLC) among several alternative groupings of European economies. The empirical strategy adopted is based on the evaluation of the time path of rolling regression estimates of the OLC for European countries. We then use a testing procedure suggested by Evans [Evans P (1996) J Econ Dynam Control 20:1027–1049] to investigate the convergence, or non-convergence, of the OLC in several groups of European countries by examining how the cross-country variance of the OLC evolves over time in these groups. A hypothesis of medium-term convergence of the OLC is rejected for most of the European country groups examined.      

Modelling profit series: nonstationarity and long memory

The paper examines the convergence properties of productivity in fifteen European countries over the period 1960-1997. European productivity is estimated using modified translog production systems with a completely general intertemporal structure. To capture the notion that trade may have an influence on aggregate convergence, imports are included in the production function. Stationarity tests are used to test for convergence around a common long-run trend, including unit root tests, the KPSS and Bayesian tests, as well as testing based on fractional differencing parameter estimation for long memory models. It is found that convergence inferences are sensitive to the type of test employed.     

Food consumption and economic development in Turkey and European Union countries

This study investigates the relationship between food consumption and economic development in Turkey and European Union countries. Differences in food diets are analysed by using data on per capita consumption in caloric terms based on the period from 1970 to 2000. The cluster analysis is employed to derive country grouping on the basis of similarities in dietary structure in the 1970 and 2000. Existence of a trend towards a common European diet is explored with Beta convergence. The empirical results show that per capita food consumption is becoming less responsive to changes in income and appears to be reaching a ceiling in the majority of EU countries and Turkey. However, the share of animal products in food consumption diet is low and income expenditure elasticity of animal products is higher with 0.84 values in Turkey than that in European countries in 2000. There are great differences in dietary structure between Turkey and the European Union. Differences also exist between European Union countries; however, despite these differences there is a general tendency for dietary structure to become increasingly similar across the majority of European Union countries. The result also supports the absence of a convergence towards a common diet if Turkey joins the European Union.     

Convergence in per capita CO2 emissions: A robust distributional approach

This paper investigates the convergence hypothesis for per capita CO₂ emissions with a panel of 166 world areas covering the period 1960–2002. The analysis is based on the evolution of the spatial distributions over time. Robust measures of dispersion, asymmetry, peakedness and two nonparametric distributional tests – shape equality and multimodality – are used to assess spatial time differences. A robust normal reference bandwidth is also applied to estimate Markov’s transition laws and its subsequent ergodic (long-run) distributions. Our results point toward non-stationary, flattening and right-skewed spatial distributions before the oil price shocks of the 1970s and more stable and symmetric shapes between 1980 and 2000 at the world level and for many country groupings (similar income, geographic neighbors, institutional partners). In the latter period, group-specific convergence patterns emerge with the clearest single-peaked and compact density shapes being reached in the wealthy, well-integrated and European countries during the last years of the panel. No significant multimodality is formally detected in the world distribution over the whole period. The Markov analysis suggests more divergence and larger per capita emissions for the world in the long run, with a doubling in median emissions and stable pollution gaps during the first 50 years of the transition. A variety of steady state distributions are identified in the country subsets.     

Convergence and catching up in ASEAN: a comparative analysis

The increasing diversity of average growth rates and income levels across countries has generated a large literature on testing the income convergence hypothesis. Most countries in South-East Asia, particularly the five founding ASEAN member countries (ASEAN-5), have experienced substantial economic growth, with the pace of growth having varied substantially across countries. Recent empirical studies have found evidence of several convergence clubs, in which per capita incomes have converged for selected groupings of countries and regions. This paper applies different time series tests of convergence to determine if there is a convergence club for ASEAN-5, as well as ASEAN-5 and the USA. The catching up hypothesis states that the lagging country, with low initial income and productivity levels, will tend to grow more rapidly by copying the technology of the leader country, without having to bear the associated costs of research and development. Given the important effects of technological change on growth, this paper also examines whether ASEAN-5 is catching up technologically with the USA.     

Price convergence of peripheral European countries on the way to the EMU: A time series approach

This paper examines price and inflation convergence between three European countries (Italy, Spain and the U.K.) and a European average and, alternatively, between them and Germany from the beginning of the 80's.  For this purpose the long-run stochastic relationships on prices derived from the convergence criteria agreed in the Maastricht Treaty are analyzed. In order to do this, some recent unit root tests have been applied as well as time-varying parameters models.  The results reject the long-run convergence hypothesis in all the cases but allow us to accept the existence of catching-up with the European average and Germany in some cases depending on the nature of the prices and on the countries considered.

Convergence and the Caribbean

This paper examines the convergence experience of selected Caribbean countries. It examines evidence of reduced dispersion in real per capita income—Sigma convergence—and ‘catch up’ growth across the group—Beta convergence. Estimation of the Solow—Swan cross-section model for the Caribbean shows weak evidence of β and σ convergence. However, structural instability and evidence of divergence over the sample period, suggest this convergence to be spurious. Further tests on individual country data showed an absense of steady state convergence for any country over time. Institutional structures and adjustments to economic shocks appear to have been important for the determination of per capita income in the long run.     

Nominal and real convergence between the CEE countries and the EU: a fractional cointegration analysis

This paper examines the real and nominal convergence between the Central and Eastern European countries and the EU, using fractional cointegration analysis for the period 1980–2003. Fractional cointegration analysis is a flexible methodology, which allows for more subtle forms of mean reversion. The tests performed are those of Geweke and Porter-Hudak. The convergence processes are valid when macroeconomic time series used in the study are fractionally cointegrated. The results indicate that inflation and interest rates series of six sample countries are fractionally cointegrated with those of the EU. Therefore, nominal convergence has been achieved by some of the transition countries, but the equilibrium errors display long memory. Results also indicate that industrial outputs of most countries in the sample are not fractionally cointegrated with that of the EU. The results further indicate that both nominal and real convergence have been achieved only for Hungary.     

Socio-Economic Gaps within the EU: A Comparison

This research investigates socio-economic gaps between countries of the European Union (EU). The countries, for comparison purposes, are grouped into five sets to find out if the different groupings differ in means and variances. The overall conclusion is that the 15 core combinations outperform the rest when comparisons are made on the basis of 45 socio-economic variables. However, the newly added countries in the enlargement appear to be fairly homogeneous when compared in accordance with the 45 variables. Of special interest is whether the inclusion of Turkey among the newly admitted would have changed the pattern of homogeneity among them. The answer to this question is a guarded yes.      

Consequences of Economic Partnership Agreements between East and Southern African Countries and the EU for Inter- and Intra-regional Integration

Abstract

The European Union is currently negotiating Economic Partnership Agreements (EPAs) with six African, Caribbean and Pacific country groupings, aiming at establishing mutual free trade. This paper empirically assesses the impact of the EPAs on trade flows and government revenues for 22 East and Southern African countries and discusses implications for intra-regional integration. The results indicate that while moderate trade effects can be expected, relatively large budget effects are likely to occur in a number of these countries, exposing them to considerable structural and financial adjustment requirements. In addition, EPAs would strengthen the need to consolidate overlapping intra-regional integration schemes.     

International Consumption Patterns among High‐income Countries: Evidence from the OECD Data*

This paper examines the effect of economic integration on the product‐level consumption patterns across the OECD in the past decade. Estimation results find evidence of strong convergence in cross‐country consumption patterns with substantial heterogeneity across products and countries. The results are robust to either the benchmark choice, data selection, or the choice of model specification. In addition to documenting convergence, the paper relates the volume of international trade to cross‐country consumption patterns.     

Europe's income convergence and the latest global financial crisis

This paper examines the effects of the 2008 financial crisis on economic growth and convergence across European countries from 1973 to 2012. Employing cross-sectional and dynamic panel data techniques, the results show that the global financial crisis has brought a greater absolute convergence rate rather than divergence, affected richer members more heavily and, presumably, allowed less developed members to recover more quickly. We find evidence that creating the European Union has contributed toward economic growth and convergence; meanwhile, no similar evidence is found concerning the European Monetary Union. Moreover, we present evidence that both the average output per capita and the rate of convergence during the financial crisis fell around 7%.     

Are Current Account Deficits Sustainable? Evidence from Dynamic Panel Data Analysis

This paper examines two issues, namely, whether the current account deficit (CAD) is sustainable, and the degree of sustainability for a panel consisting of 129 countries over the period 1981–2013. To this end, we investigate the relationship between exports and imports for various income and region categories. Our finding from the pooled mean group estimator suggests that CAD is “weakly” sustainable in most of the country groups. This implies that sustainable current account is consistent with the sustainability of external debts. Further, the adjustment coefficient is found to be rather low for all the country groups. This indicates that the speed of convergence toward the long-run equilibrium in the event of short-run disturbances is faster. Finally, we discuss policy implications of our findings.

     

Energy efficiency in transition economies

This article outlines and estimates a measure of underlying efficiency in electricity consumption for an unbalanced panel of 27 transition economies and 6 European OECD countries between 1994 and 2007. A Bayesian Generalized True Random Effects stochastic frontier model with persistent and transient inefficiency is considered by estimating an aggregate electricity demand function that leads to consumption efficiency scores, giving further insights than a simple analysis of energy intensity. There is evidence of convergence between the CIS countries and a block of Eastern European and OECD countries, although other country groups do not follow this tendency, such as the Balkans.     

European Sector Returns and Capital Market Integration

The paper tests European capital market integration at the sector level. It examines the recent trend of sector‐level returns for four European countries, France, Germany, Italy, and the UK, using “return on assets” of a panel of listed firms of these countries for the period 1988–95. Initial findings suggest that sector returns have converged across countries over time. However, when integration is tested within a capital‐asset pricing model framework, the country effect remains strong. The overall results support the view that European capital market integration is under way, but is far from complete.     

The effect of a currency union on trade: Lessons from the Irish experience

This paper studies the introduction of an exchange rate between Ireland and the UK in 1979 to shed light on the effects of a common currency on the composition of international trade. No evidence is found from time series or panel regressions that the change of exchange rate regime had a significant effect on Anglo-Irish trade. This finding is consistent with previous studies of currency unions between larger, developed countries but conflicts with findings based on more heterogeneous country groupings. The reasons for this discrepancy are discussed.     

FISCAL INDULGENCE IN CENTRAL EUROPE: LOSS OF THE EXTERNAL ANCHOR?

In recent years, fiscal performance in Central Europe has steadily deteriorated, in contrast to the improvement in the Baltics. This paper explores the determinants of such differences among countries on the path to European Union (EU) accession. Regression estimates suggest that economic and institutional fundamentals do not provide a full explanation. An alternative explanation lies in the political economy of the accession process, and a game‐theoretic model illustrates why a country with a stronger bargaining position might have an incentive to deviate from convergence to the Maastricht criteria. The model generates alternative fiscal policy regimes – allowing for regime shifts – depending on country characteristics and EU policies.     

Do per capita health care expenditures converge among OECD countries? Evidence from unit root tests with level and trend-shifts

This study examines the stochastic conditional convergence of per capita health care expenditures (PCHCE) among 19 OECD countries over the period 1972–2008. Specifically, newly developed LM and RALS-LM unit root tests with allowance for two endogenously determined structural breaks are employed. The results indicate support for PCHCE convergence among most OECD countries. The results are stronger in more general tests that control for two breaks and nonnormal errors. Panel unit root tests provide additional support for the stochastic convergence of PCHCE.     

Testing convergence of European regions: A semiparametric approach

We provide a reappraisal of income convergence across European regions over the last two decades by using a semiparametric partially linear model to approximate the relationship between the average growth rate of GDP per capita and the initial GDP per capita. Estimation results point out both country heterogeneity and non-linearity in the convergence process. The findings suggest that low income regions, in particular those from new adhesion countries, diverge while medium income regions converge and that there is no evidence of convergence for high income regions.     

Human Capital and the Convergence Process Among Countries

This paper examines the convergence process across countries for the period 1980–2000, giving special attention to the role of human capital as a conditioning factor. The originality of the study is in the use of new proxies for human capital, such as publications and patents ratio and the patents/articles ratio which reflect the efficiency of the scientific work, in contrast to the quantitative measures usually used in the growth literature. The analysis suggests that: (i) convergence is conditional on structural factors, population growth, human and physical capital; (ii) the new proxies of human capital control fairly well the different steady‐states among countries; (iii) the different levels of human capital affect countries differently, according to their levels of development. Higher levels of human capital are suitable to differentiate the convergence process among developed countries, and basic or intermediate levels are more suitable to differentiate convergence among the less developed countries.
