Convergence in Interest Rates and Inflation Rates Across Countries and Over Time

We examine the relationship between interest rates and inflation rates for 10 countries during the period 1974–95. We find evidence of a unique cointegrating relationship between nominal interest rates of European Monetary System (EMS) countries, the US and Canada, and the US, Germany, and Japan. No similar relationship is obtained between inflation rates with one exception, namely, that between the US and Canada. We interpret these results as convergence in inflation but not in interst rates. Hence, if interest rates represent an indicator of monetary policy, the countries considered have attempted to implement independent policies but not to an extent which produced divergent trends in inflation.     

A simple inflation indicator for the euro zone

This article proposes and estimates an inflation indicator for the European Monetary Union (EMU). This indicator is set up so that it is contemporarily not affected by the changes in price differentials among EMU countries. The results show that the Monetary Union Index of Consumer Prices (MUICP), which is the inflation measure that the European Central Bank (ECB) takes as a reference for monetary policy purposes, could be understating the value of the inflation in the euro zone. It is also concluded that regional peculiarities are fundamental in the evolution of prices in the different EMU countries.     

Catching up: The role of demand, supply and regulated price effects on the real exchange rates of four accession countries

The main aim of this paper is to examine the exchange rate behaviour of a group of four transitional, EU accession countries, with a view to making policy recommendations regarding their full accession to the European Monetary Union. We employ a dynamic OLS panel estimator to investigate the relative importance of demand and supply influences on the exchange rates of these countries. Our analysis shows that both supply‐ and demand‐side effects are important for the accession countries, although their overall effect on inflation differentials and competitiveness seems to be small. An additional focus of the paper is the examination of the role that administrated, or regulated, prices and the productivity of the distribution sector play in the real exchange rate dynamics. Using a unique database we show that administrative prices have been a powerful force behind price and real exchange developments for our group of accession countries. The distribution sector is shown to have an independent effect on the internal price ratio over and above that generated by the Balassa–Samuelson effect.     

The enlargement of the euro area: differences in relative inflation

This paper investigates the structural determinants of relative inflation (i.e. the inflation of non‐tradables vs tradables) in the context of overall inflation differentials in the EU. The analysis is based on the Bergstrand theoretical model. This framework incorporates three alternative hypotheses of relative inflation (Harrod–Balassa–Samuelson, relative factors endowment, and demand effects). Due to the lack of reliable data on capital stocks only a curtailed version of the model is tested here empirically. The various specifications of the model are estimated for the majority of EU countries, using the Pedroni panel group mean FMOLS estimator. In general, relative labour productivity and demand factors turn out to be significant and correctly signed, though evidence in favour of the latter effect seems to be less robust. In addition, differences in the determination of relative prices between the new and old EU Member States are found. They seem to be consistent with theoretical considerations and the transition phenomenon. The estimation results are very sensitive to the definition of non‐tradables. The paper also discusses policy implications for overall inflation, stemming from relative price models. It questions the usefulness of relative inflation models for the analysis of overall inflation differentials and practical policy decisions.     

Nontraded Goods and Real Exchange Rates in a Multi‐Good Ricardian Model

The two‐country Ricardian trade model with discrete goods and uniform transport costs for tradable goods is applied to the decomposition of the real exchange rate into traded and nontraded components. The real exchange rate is driven almost entirely by changes in the productivity differentials in nontraded goods and also explains the Balassa–Samuelson effect of a lower cost of living in poor countries, but extraordinary transport costs for some nontraded goods are necessary to easily explain the Balassa–Samuelson effect.     

Testing similarities of short-run inflation dynamics among EU-25 countries after the Euro

In this paper, we introduce two new definitions of pair-wise and multi-wise similarity between short-run dynamics of inflation rates in terms of equality of forecast functions and show that in the context of invertible ARIMA processes the autoregressive metric introduced by Piccolo (1990) is a useful measure to evaluate such similarity. Then, we study the similarity of short-run inflation dynamics across European Union (EU)-25 Member States during the Euro period. Consistent with studies on inflation differentials and inflation persistence, our findings suggest that after seven years from the launch of the Euro the degree of similarity of short-run inflation dynamics across Euro area countries is still weak. By contrast, we find that EU countries not adopting the common currency, whether old EU or new accession Members, display a higher degree of inflation dynamics similarity both among each other and with Euro area countries.     

Coordination versus flexibility in wage formation: a focus on the nominal wage impact of productivity in Germany,Greece, Ireland,Portugal, Spain and the United States

Wage coordination between countries of the European Monetary Union (EMU) aims at aligning nominal wage growth with labour productivity growth at the national level. We analyse the developments in Germany, the EMU’s periphery countries Greece, Ireland, Portugal and Spain along with the United States over the period 1980 to 2010. Apart from the contribution of productivity to nominal wages, we take into account the contributions of prices, unemployment, replacement rates and taxes by means of an econometrically estimated nonlinear equation resulting from a wage bargaining model. We further study the downward rigidities of nominal wages. The findings show that in past times of low productivity, price inflation and reductions in unemployment still put significant upward pressure on nominal wage growth. The periphery countries are far from aligning nominal wage growth with productivity growth. German productivity is a major wage determinant, but surely not the only one. Within the context of a free bargaining process between employers and labour unions, policy-makers can effectively use the replacement rate to steer the nominal wages outcome.     

Determinants of sovereign bond yield spreads in the EMU: An optimal currency area perspective

In the light of the recent financial crisis, we take a panel cointegration approach that allows for structural breaks to the analysis of the determinants of sovereign bond yield spreads in nine economies of the European Monetary Union. We find evidence for a level break in the cointegrating relationship. Moreover, results show that (i) fiscal imbalances – namely expected government debt-to-GDP differentials – are the main long-run drivers of sovereign spreads; (ii) liquidity risks and cumulated inflation differentials have non-negligible weights; but (iii) all conclusions are ultimately connected to whether or not the sample of countries is composed of members of an Optimal Currency Area (OCA). In particular, we establish (i) that results are overall driven by those countries not passing the OCA test; and (ii) that investors closely monitor and severely punish the deterioration of expected debt positions of those economies exhibiting significant gaps in competitiveness.     

Reallocation and restructuring: A generalization of the Balassa–Samuelson effect

Despite its strong theoretical position when it comes to explaining inflation in transition economies, the empirical findings of the Balassa–Samuelson (B–S) effect assign only a minor role to structural inflation – to the disappointment of analysts and policymakers. This article points to 3 theory-based contributing factors to these ‘weak’ findings and offers an alternative methodological approach. First, a short-term focus makes B–S prone to underestimating the magnitude of the productivity growth differential. Second, the conventional demand side CPI based definition of sectoral value added reduces the extent to which the productivity growth differential is passed through to inflation. Third, by ignoring the dependence between the 2 main B–S components, a further downward bias to the productivity growth pass through comes about. The key to our proposed alternative methodology centres on an endogenous relation between the productivity growth differential and sector sizes. Together with the long-run supply-side approach this allows us to capture inflation drivers that conventional B–S fails to incorporate. In our extension to the conventional B–S model a reduced productivity growth differential can be compensated by an increased productivity growth pass-through, or vice versa – with the effect of augmenting inflation pressure. Hence, the link between productivity growth differentials and the dynamics of structural inflation is shown to be more complex than previously assumed.     

Globalization, the output-inflation tradeoff and inflation

This paper provides comprehensive evidence on the relation between inflation and globalization, defined here as trade and financial openness, using a large cross-section of 91 countries over the period 1985-2004. We establish two main empirical regularities: both higher trade and financial openness (i) reduce central banks’ inflation bias, yielding lower average inflation and (ii) are associated with a larger output-inflation tradeoff. This evidence is at odds with the standard Barro-Gordon framework, which would require globalization to have a negative effect on the output-inflation tradeoff to yield lower equilibrium inflation, but it is consistent with a recent strand of new Keynesian models emphasizing the role of imperfect competition and nominal rigidities. Our findings also support the relevance of the time-inconsistency hypothesis, which underlies the theoretical models predicting a relation between globalization and inflation. For the OECD subsample, however, we do not find an effect of openness on inflation (the output-inflation tradeoff), suggesting that these countries have created an institutional framework for central banks that eliminates distortions due to the time-inconsistency problem.     

Monetary Policy, Nominal Interest Rates, and Long–Horizon Inflation Uncertainty

Empirical evidence presented in this paper shows that the predictability of inflation at long horizons varies considerably across countries. Both simple theory and empirical evidence suggest that the crucial factor is the extent to which systematic monetary policy succeeds in preventing a unit root in inflation. The mechanism by which it does this appears however to be complicated by strong empirical evidence that nominal as well as real interest rates have real effects, which implies that monetary policy need not be so vigorous in reactions to inflation. This helps to explain why inflation rates in the US and (especially) Germany have been relatively predictable, despite monetary policy rules which appear to have been barely stabilising. The paper also presents tentative evidence that the power of nominal interest rate effects is inversely related to long–horizon inflation uncertainty, and hence ultimately uncertainty about monetary policy.     

THE INTERNATIONALIZATION OF AGRICULTURAL TECHNOLOGY: PATENTS, R&D SPILLOVERS, AND THEIR EFFECTS ON PRODUCTIVITY IN THE EUROPEAN UNION AND UNITED STATES

Multilateral indices of total factor productivity (TFP) allow efficiency comparisons between ten European Union countries and the United States from 1973 to 1993. Differences in TFP levels are then explained by land quality differences, public research and development (R&D) expenditures, education levels, private-sector patents, international spillovers of public R&D, and private-sector technology transfer. There is evidence that public R&D results in limited knowledge spillovers between the European countries and the United States. However, the use of international patent data from the Yale Technology Concordance shows not only that patents matter, but also that private sector technology transfer may be the dominant force in explaining TFP trends. The United States and the European Union countries with more advanced research systems (Netherlands, Denmark, France, and Belgium) converge in a high-growth club, while Germany, Luxembourg, Greece, Italy, Ireland, and the United Kingdom form the slow-growth group. Ignoring knowledge spillovers and technology transfer leads to biased estimates of R&D elasticities, which is hardly surprising since the private sector is now spending more than the public in some of these countries. Thus, the estimated rate of return to public agricultural R&D falls from over 60% in the closed economy model to 10% in the model that takes account of international spillovers. (JEL Q16)     

Real wages,inflation and labour productivity in Australia

This article presents an analysis of real wages, inflation and labour productivity interrelationships using cointegration, Granger causality and, most importantly, structural change tests. Applications of tests to Australian data over the 1965 to 2007 period corroborate the presence of a structural break in 1985 and show that a 1% increase in manufacturing sector real wages led to an increase in manufacturing sector productivity of between 0.5% and 0.8%. Comparable estimates for the effect of inflation on manufacturing sector productivity have limited statistical significance. Granger causality test results suggest that real wages and inflation both Granger cause productivity in the long run.     

Inflation convergence in Central and Eastern Europe vs. the Eurozone: Non‐linearities and long memory

In this paper, we consider inflation rate differentials between seven Central and Eastern European Countries (CEECs) and the Eurozone. We test for convergence in the inflation rate differentials, incorporating non‐linearities in the autoregressive parameters, fractional integration with endogenous structural changes, and also consider club convergence analysis for the CEECs over the period 1997 to 2015 based on monthly data. Our empirical findings suggest that the majority of countries experience non‐linearities in the inflation rate differential; however, there is only evidence of a persistent difference in some countries. Complementary to this analysis we apply the Phillips and Sul (2007) test for club convergence and find that there is evidence that most of the CEECs converge to a common steady state.     

Unions,wages and productivity: some evidence from UK engineering firms

Estimates of union wage and productivity effects are derived using primary micro-level panel data for a sample of firms in the UK engineering industry. Union wage differentials of the order of 10% are suggested from the results, whereas union productivity impacts appear to be non-linear with respect to union density.     

Balassa-Samuelson Theory and Predictability of the US/UK Real Exchange Rate

This paper performs a theory-based forecast of the US/UK real exchange rate. The theory is the Balassa-Samuelson hypothesis that productivity differentials between two countries would determine long-run movements of real exchange rates. The relative income and real exchange rate set a bivariate system, which considers the heteroskedasticity in the real exchange rate movements. The model, to which the Kalman filter and Markov-switching algorithm are applied, is compared with the random walk model and reports significant improvements in forecasting in the medium and long term.

Asymmetric behavior of inflation differentials in the euro area: Evidence from a threshold unit root test

This paper tests the existence of persistent inflation rate differentials in the euro area by employing linear as well nonlinear unit root tests. Besides linear unit root tests, a two-regime threshold unit root test examines the conjecture that inflation rate differentials follow a nonlinear two-regime process towards a threshold, switching from the persistent regime to the transitory one and vice versa. The results imply that threshold nonlinearity is confirmed in 10 out of the 16 cases. However, we have found unit root regime-switching behavior only in six out of the 16 cases under investigation. This finding implies that these inflation rate differentials were persistent when they were low (regime 1), but transitory when they were high (regime 2). This asymmetric behavior can possibly be explained by the different degree of pressure exercised on governments, which is accompanied with different inflation rate differentials. On the contrary, despite the evidence of nonlinearity, the majority of the inflation rate differentials are found to be monotonically persistent. Our results have strong implications for policy makers. In particular, the documented persistency in the inflation rate differentials might have long-run costs in terms of price and macroeconomic stability.     

Convergence in Per Capita Income Levels, Productivity Dynamics and Real Exchange Rates in the EU Acceding Countries

During a catch up process – such as the one that thecountries acceding to the EU are undergoing – there emergesa fundamental economic link between nominal and realvariables which surfaces in the dynamics of the realexchange rate (the ``Balassa–Samuelson effect'). Thisarticle analyzes some of the implications of this process forthe acceding countries addressing three main issues.First it focuses on the empirical measurement of convergencebetween acceding countries and EU-member states. Thenit analyzes the economic fundamentals of a catch up processarguing that for this process to be self-sustained, it must bebased on differential productivity growth whereby productivityin the acceding countries grows faster than that in the incumbents.Thirdly, an attempt is made to test empirically theBalassa–Samuelson effect in the EU acceding countries. Finally the article discusses some of the policy implications of thedichotomy ``real-cum-nominal convergence' on the way to EUand EMU accession.     

Labor shares in the old and new EU member states - Sectoral effects and the role of relative prices

The paper studies the labor share among countries of the European Union, with a particular attention to the newer member states of Central and Eastern Europe (CEEU). We find that CEEU countries typically have lower labor shares than older EU member states, both in the aggregate and at the sectoral level. Structural change, while quite pronounced among the CEEU economies, plays only a minor role in the evolution of the labor share. The exception is agriculture, which for some countries has a sizable impact on the level and dynamics of the labor share - partly because of important measurement problems. We also find that a significant part of the difference in conventionally measured labor shares between the more developed EU countries and less developed CEEU countries can be attributed to differences in relative prices. This is consistent with a productivity-based explanation: we show that a simple, calibrated two-sector model with sectoral productivity differentials can explain 36–71% of cross-country variations in the non-agricultural labor share.     

Inflation and Productivity in Europe: An Empirical Investigation

Motivated by the ``Maastricht proposition' that nominal convergence will generate significant real benefits, the paper investigates the inflation-productivity nexus in fifteen European countries over the period 1960–1997. Modern econometric techniques organised around I(1) and cointegration analysis are used to test for the existence of a long-run relationship between inflation and productivity. Bayesian and recently developed causality testing procedures are employed to examine the inflation-productivity relationship. The empirical results suggest the existence of causality in seven countries. Causality is bi-directional in five cases. Notably, causality fails exactly where the ``Maastricht proposition' would be more useful: The European South and the smaller member states of the Union.
