Intertemporal sustainability of current account imbalances: New evidence from the OECD countries

This study estimates the intertemporal model for the relationship between exports and imports and examines the sustainability of current account deficits (CADs) and the validity of intertemporal budget constraint for 24 Organisation for Economic Co‐operation and Development countries. The standard ordinary least squares (OLS)‐based two‐step Engle and Granger test, the cointegration regression Durbin–Watson (CRDW) test, and the Stock–Watson test performed on the one‐regime model with time‐invariant parameters and no structural break provide mixed support for the presence of cointegration between exports and imports. The recursive least squares‐based cumulative sum of recursive residuals (CUSUM) and the cumulative sum of squares of recursive residuals (CUSUMSQ) tests and the OLS‐based Andrews‐Quandt (AQ) and Andrews – Ploberger (AP) tests suggest the presence of structural breaks in the long‐run relationship between exports and imports for a number of countries. The end‐of‐sample new cointegration breakdown tests performed on the OLS, fully modified OLS, and full‐information maximum‐likelihood estimates of the model suggest the presence of cointegration between exports and imports for most countries. The dominant support for cointegration between trade flows points toward the sustainability of CADs and the validity of intertemporal budget constraint. The macroeconomic stabilization policies seem to have been effective in correcting the market failures and maintaining the steady‐state equilibrium relationship between trade flows in the sample countries. The findings of this study have important implications for empirical research. The structural breaks in the cointegrating vector could occur even over the short time periods and at any point in time. It is essentially important to assess the sustainability of the external position in the presence of long‐period as well as short‐period breaks in the cointegrating vector.     

The monetary transmission mechanism: Evidence from the industries of five OECD countries

This paper studies the monetary transmission mechanism using disaggregated industry data from five industrialized countries. Our goal is to document the cross-industry heterogeneity of monetary policy effects and relate it to industry characteristics suggested by monetary transmission theories. Sizable and significant cross-industry differences in the effects of monetary policy are found. Such differences swamp the hardly detectable cross-country variability. Sectoral output responses to monetary policy shocks are systematically related to the industry output durability, financing requirements, borrowing capacity and firm size. These findings are consistent with a quantitatively non-negligible role of financial frictions in the monetary transmission.     

Trade effects of monetary agreements: Evidence for OECD countries

This paper analyses the effects of monetary agreements on trade flows using a sample of 25 OECD countries over the period 1950-2004. We find that these agreements have boosted intra-bloc trade. This result especially applies to the case of the euro. More importantly, in contrast to regional trade agreements, all monetary agreements analysed show evidence of trade-creating effects with third countries. Finally, only the euro shows a symmetric impact for the trade-creating effect with non-members, that is, using the euro promotes both the Eurozone's exports and its imports to non-Eurozone markets to a similar extent.     

Smooth transition,non-linearity and current account sustainability: Evidence from the European countries

In this paper we examine three types of nonlinearities, i.e., nonlinearity stemming from structural breaks, sign nonlinearity and size nonlinearity, for ten European countries and their importance to current account sustainability. For this purpose, we apply a battery of linear and nonlinear unit root tests. Our results show that the structural break nonlinearity and size nonlinearity are vital to the current account-GDP ratios of European countries in testing for the null hypothesis of a unit root. Nevertheless, the current account-GDP ratios of these countries do not exhibit the sign nonlinearity. That is, by taking account of the nonlinear trend, the threshold autoregressive and momentum threshold autoregressive models do not detect any asymmetry in the response of the current account imbalance to deviations from its long-run nonlinear trend.     

Financial markets, the pattern of industrial specialization and comparative advantage: Evidence from OECD countries

Due to underlying technological and organizational differences, industries differ in their need for external finance. Since services provided by the financial sector are largely immobile across countries, the pattern of industrial specialization should be influenced by the level of financial development. Among OECD countries we find a strong causal effect of the financial sector on industrial specialization. Further, the financial sector is a source of comparative advantage in a way consistent with the Hecksher-Ohlin-Vanek model. Results are also presented on which aspects of financial systems are important for specialization and comparative advantage.     

Monetary shocks,exchange rates and trade balances: Evidence from inflation targeting countries

This paper investigates the relationship among monetary policy shocks, exchange rates and trade balances in five Inflation Targeting Countries (ITCs). The investigation is based on Structural Vector Error Correction Models (SVECMs) with long run and short run restrictions. The findings reveal that a contractionary monetary policy shock leads to a decrease in price level, a decrease in output, an appreciation in exchange rate, and an improvement in trade balance in the very short run. Our findings contradict the findings of price, output, exchange rate and trade puzzles that have been found in many empirical studies. Furthermore they are consistent with the theoretical expectations regarding the effect of a contractionary policy. The only long run restriction that we imposed on our models is that money does not affect real macroeconomic variables in the long run, which is consistent with both Keynesian and monetarist approaches.     

Labour Demand and Wage-induced Innovations: Evidence from the OECD countries

This paper shows that increasing real wages steepens or reverses the slope of the labour demand schedule because increasing wages give firms incentives to innovate and to invest in newer and more efficient vintages of capital. Using macroeconomic data for the OECD countries it is shown that the efficiency inducement of higher real wages steepens the traditional neoclassical labour demand function substantially. Taking into account the adverse demand effects of wage reductions it is doubtful that real wage reductions are a cure for the unemployment problem in the OECD countries.     

Creative accounting and electoral motives: Evidence from OECD countries

Using an unbalanced panel of 27 OECD countries over the period 1970–2011, I examine whether electoral motives influenced creative accounting. Governments engage in “below-the-line” operations, such as transactions in financial assets, that do not show up in the deficit figures but give rise to changes in debt. I use the difference between the change in public debt and the deficit (stock-flow adjustment) to measure creative accounting. The results suggest that governments strategically engaged in creative accounting before regular elections so as to sugarcoat the budget balance. I also provide an overview of government interventions that gave rise to large stock-flow adjustments.     

Voting on social security: Evidence from OECD countries

We test the subset of models of public choice of social security that have empirical predictions. The data, collected for this paper from the OECD countries for the years 1960, 1970, 1980, and 1990, provide some support for each of the theories. Higher median voter age, more income heterogeneity, greater similarity in family size, and variables that make a public pension program more profitable are all associated with a larger program. However, none of the theories explains why the shape of the age distribution and the time trend are so important. The results are robust under both fixed effects and random effects estimation.     

The fundamentals of sovereign debt sustainability: evidence from 15 OECD countries

We study the sustainability of sovereign debt accumulation in 15 OECD countries using quarterly data from 1980 to 2010 with a focus on how and in what countries debt sustainability changed after the commencement of the Euro Convergence Criteria in 1997 as well as after the financial meltdown in 2007. We define sustainability as the validity of the inter-temporal budget constraint of the government and test a sufficient condition motivated by Bohn (Q J Econ, 113(3):949–963, 1998) using single-country and pooled regressions. We find evidence that the Euro Convergence Criteria contributed to the sustainability of debt accumulation. Further, while the yield spreads suggest the debt crisis is a problem of the southern Euro countries, we find a lack of debt sustainability for Greece, Portugal and France but not for Italy and Spain. In terms of debt sustainability, the crisis adversely affected primarily stand-alone countries rather than members of the European Monetary Union. Nevertheless, yield spreads increased more in the southern countries of the monetary union than in stand-alone countries. Our results support the view that countries within a monetary union are more prone to investors’ sentiments than stand-alone countries.     

Disentangling the wage-productivity relationship: Evidence from select OECD member countries

Conventional theory proposes that firms reward productivity improvements with higher wages. Conversely, efficiency wage theory suggests that wages can induce greater productivity. This paper applies a statistical technique that disentangles the potential bidirectional feedback between wages and productivity. Wage strategies in six industrialized countries with various labor market institutions are examined. Conventional and efficiency wage practices vary systematically across the industrialized countries; these variations are consistent with the expected effects of labor market institutions.     

Determinants of the sacrifice ratio: Evidence from OECD and non-OECD countries

This paper measures sacrifice ratios for all countries in the world over an approximately forty year time period, in addition to exploring the determinants of worldwide sacrifice ratios. We test the most commonly-cited determinants: the speed of disinflation, openness, inflation targeting, central bank independence, and political factors for both OECD and non-OECD countries. We find that the speed of disinflation is the most important determinant of OECD sacrifice ratios, but puzzlingly has no effect on non-OECD nations' disinflation costs. Instead we find evidence that greater central bank independence and more openness are associated with lower non-OECD sacrifice ratios. We also find that the ratio of government debt to GDP – a variable that is not important when it comes to OECD countries – is highly significant for non-OECD economies. Specifically, we find that higher indebtedness is associated with lower sacrifice ratios in non-OECD nations, suggesting that greater levels of debt do not lead to higher expectations of inflation. Furthermore we find evidence that the negative impact of debt on non-OECD sacrifice ratios is being driven by middle income economies.     

Limits to government debt sustainability in OECD countries

The recent euro area sovereign debt crisis has shown the importance of market reactions for the sustainability of debt in advanced economies. This paper calculates endogenous government debt limits given the markets assessment of the probability to default. The estimated primary balance reaction function to growing debt has the “fiscal fatigue” property (a loosening fiscal effort makes the primary balance insufficient to support rising debt) at high debt levels. The combination of this feature of the primary balance reaction function with the market interest rate reaction to growing debt determines the government debt limit beyond which debt cannot be rolled over. An application to OECD countries over the period 1985 – 2013 with a model-based risk-premium shows that current debt limits are high for most of the OECD thanks to particularly low risk-free interest rates. It also shows for some countries that current debt levels are not sustainable without a change in government behaviour. Most importantly, the framework illustrates the state contingent nature of debt limits and therefore the vulnerability of governments to a change in macroeconomic conditions and to market reactions. Last, computations with an estimated interest rate reaction to public debt illustrate that debt limits are lower in the euro area than in other countries because of a sharper market interest rate reaction to rising debt.     

Personal income tax progressivity and output volatility: Evidence from OECD countries

This paper investigates empirically the effect of personal income tax progressivity on output volatility using macro data from a sample of OECD countries over the period 1982–2009. Our measure of progressivity is based on the difference between the marginal and the average personal income tax rate for the average production worker. We find supportive empirical evidence for the hypothesis that higher personal income tax progressivity leads to lower output volatility. This effect comes in addition to the stabilizing impact of government size and it is equally important in economic terms. All other factors constant, countries with more progressive personal income tax systems seem to benefit from stronger automatic stabilizers.     

On the permanent effect of an aggregate demand shock: Evidence from the G-7 countries

This paper extends the work of Cover, Enders and Hueng (2006) to examine the idea that an aggregate demand shock may have permanent effect on the output level by indirectly shifting the aggregate supply curve. We utilize the bivariate SVAR modeling and adopt an identification scheme, which allows for the possibility that a shift in the aggregate demand curve may induce the long-run aggregate supply curve to shift. We have shown that aggregate supply shocks are positively affected by the demand shocks in each of the G-7 countries. It is found that a one-time positive aggregate demand shock increases the output level permanently in these industrialized economies. We have also shown that our decomposition strategy can help resolve anomalies in the responses of inflation to a positive aggregate supply shock observed in a simple Blanchard-Quah decomposition.     

Trade and business cycle synchronization in OECD countries—A re-examination

This paper re-examines the relationship between trade intensity and business cycle synchronization for 21 OECD countries in the period 1970-2003. Instead of using instrumental variables, we estimate a multivariate model including variables capturing specialization and similarity of economic policies. We confirm that trade intensity affects synchronization, but the effect is much smaller than previously reported. Other factors, like specialization and convergence in monetary and fiscal policies, have a similar impact on business cycle synchronization as trade intensity. The effect of trade on synchronization is not driven by outliers. However, the impact of trade on synchronization is not robust across deciles.     

Causal Relationship Between the Current Account and Financial Account

We demonstrate that a different causal relationship exists between the current and financial accounts in developed and developing countries. Using the Granger causality test, we clearly determine that the financial account is by and large responsible for the current account in developing countries; instead of financing the current account, the financial account thrusts the current account into an imbalance. In developed countries, however, the current account leads the way, and the financial account, as its name indicates, serves to finance a current account imbalance. This represents a forewarning that countries, which lack a sophisticated financial system to channel funds to proper locations, should not recklessly liberalize capital mobility.The author would like to thank an anonymous referee for valuable suggestions.     

Trend shocks and the countercyclical U.S. current account

From 1960 to 2009, the U.S. current account balance has tended to decline during expansions and improve in recessions. We argue that shocks to the trend growth rate of productivity can help explain the countercyclical U.S. current account. Our framework is a two‐country, two‐good business cycle model in which international asset trade is limited to a single, non‐contingent bond. We identify trend and transitory shocks to U.S. productivity using generalized method of moments (GMM) estimation. The specification that best matches the data assigns a large role to trend shocks. The estimated model also captures key facts regarding international co‐movement.     

The effects of economic and political integration on fiscal decentralization: evidence from OECD countries

Abstract .  This paper examines the impact of economic and political integration on the vertical government structure. It argues that, by increasing the market size and the benefits of decentralized provision of public goods, integration triggered the recent process of decentralization in OECD countries. A panel analysis relates the degree of fiscal decentralization to economic and European integration, controlling for interregional heterogeneity, economies of scale, and institutions. The results mostly support a decentralizing effect of economic integration in general and of European integration in particular for heterogeneous EU countries, whereas participation of subnational governments in national decision-making is associated with more centralization.     

Employment to output elasticities and reforms towards flexicurity: Evidence from OECD countries

Labor market reforms in the direction of “flexicurity” have been widely endorsed as a means to increase an economy's ability to adjust to negative shocks while offering adequate social safety nets. This paper empirically examines how such reforms influence employment's responsiveness to output fluctuations (employment–output elasticity). To address this question, we employ a single equation error correction model with policy interactions on a panel of OECD countries, which also incorporates the period of the Great Recession, and distinguish between passive and active labor market policy types. Flexicurity is represented by three policy measures: unemployment benefit generosity, the flexibility of hiring and firing rules, and spending on active labor market policies. We find that the effects of any single policy change are shaped by the broader existing policy mix within which it takes place. A hypothetical flexicurity reform towards the policy mix of Denmark, a well-known example of the flexicurity regime, is found to increase or leave unchanged countries' short-run employment–output elasticities, depending on the initial policy mix. These results are robust to accounting for a large set of additional labor market institutions.
