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.     

Capital mobility and foreign debt sustainabilty: some evidence from Turkey

This paper address the extent of capital mobility and foreign debt sustainability in Turkey over the 1962–2003 period by examining the relationship between saving and investment, and imports and exports, respectively. The empirical investment is based on cointegration, error correction models, and threshold and momentum threshold autoregressive models. Our findings are consistent with the existence of capital mobility and the ‘Strong’ form of foreign debt sustainability.     

Mexico's Economic Growth and the Balance of Payments Constraint: A cointegration analysis

This paper applies the basic balance-of-payments constraint model (BPCmodel), developed by A.P. Thirlwall, to the analysis of Mexico's economic growth in 1950-96.With the use of unit-root tests and cointegration analysis it estimates the long-run association between the growth of Mexico's real exports and real output in 1950-96, and selected subperiods. The results tend to show significant and positive cointegration between these two variables, thus giving support to the BPC-model as a relevant hypothesis to explain Mexico's long-term economic growth. Moreover, the findings of cointegration tests for selected subperiods suggest that the slowdown in its economic growth since 1982 is associated with an increase in the long-term income elasticity of imports that made more binding the balance-of-payments constraint on the expansion of domestic output.     

The sustainability of the current account in the Czech Republic,Hungary and Slovenia

The aim of this paper is to investigate empirically the sustainability of the current account in three Central European countries, the Czech Republic, Hungary and Slovenia, since their move towards market economy about 15 years ago. The analysis is based on the intertemporal approach to the current account which states that if real exports and real imports are integrated of order one then cointegration between them is a necessary and sufficient condition for the economy to satisfy its intertemporal budget constraint. On the basis of various unit-root and cointegration tests on the shares of real exports and imports in real GDP, this study concludes that the Czech Republic and Slovenia are not in violation of their intertemporal budget constraint and their trade imbalances are sustainable. However, the real exports and imports of these countries, and also the export, import measures of Hungary, do not seem to behave as random walks, excluding the possibility of cointegration between them.      

Long-run income and price elasticities of demand for Colombian nontraditional exports: a multivariate cointegration framework

A long run income and price elasticities of demand is estimated for Colombian nontraditional exports through a multivariate cointegration analysis. Based on the combination of cointegration and exogeneity concepts and the inclusion of the complete dynamic system, the paper shows the existence of a long-run relationship among nontraditional exports, relative price and foreign demand, and higher long-run elasticities than those provided by the long-run cointegration vector coefficients that are usually reported in the trade literature.     

Estimating Income and Price Elasticities of Trade in a Cointegration Framework

This paper presents further evidence on the empirical regularity known as the "45-degree rule." Income and price elasticities of trade are estimated for 21 countries in a cointegration framework. More specifically, the autoregressive distributed lag (ARDL) modeling approach and the DOLS procedure are adopted to estimate the long-run structure. The empirical results confirm the existence of a systematic relationship between growth rates and income elasticity estimates: faster growing economies have high income elasticities of demand for their exports but lower import elasticities, which implies that faster growth can be observed without any marked secular trend in real exchange rates.     

Tourism,trade and growth: the case of Cyprus

Although the relationship between international trade and economic growth has found a wide application area in the literature over the years, this can not be said about tourism and growth or trade and tourism. This study employs the bounds test for cointegration and Granger causality tests to investigate a long-run equilibrium relationship between tourism, trade and real income growth, and the direction of causality among themselves for Cyprus. Results reveal that tourism, trade and real income growth are cointegrated; thus, a long-run equilibrium relationship can be inferred between these three variables. On the other hand, Granger causality test results suggest that real income growth stimulates growth in international trade (both exports and imports) and international tourist arrivals to the island. Furthermore, growth in international trade (both exports and imports) also stimulates an increase in international tourist arrivals to Cyprus. And finally, real import growth stimulate growth in real exports in the case of Cyprus.     

Coffee exports and industrialization in Brazil

We investigate the dynamic relationship between coffee exports and machinery imports in Brazil from 1869 to 1939. Our tests reveal cointegration and bidirectional causality in the temporal sense. This evidence suggests that foreign exchange real revenues from coffee exports were important for the onset of industrialization, as machinery imports proxy for real investment demand. Capital growth, in turn, also helped to boost the country’s exports.     

Government Expenditures and Revenues in Italy in a Long-run Perspective

The aim of this study is to investigate the sustainability of Italian public accounts using in a long-run perspective, using empirical tests on sustainability and solvency of the country’s fiscal policies. The results of unit root and stationarity tests show that government expenditures and revenues series are first-differences stationary. The empirical analysis considered both the entire period and two sub-periods (1862–1913, 1947–2013). Furthermore, we conduct tests on cointegration, which evidence that a clear long-run relationship between public expenditure and revenues emerges only for the years 1862–1913. In essence, the paper’s results reveal that Italy have sustainability problems in the republican age.

     

Intertemporal Solvency in the Small Open Economy of Australia

This paper employs cointegration and multicointegration analysis to explore the issue of external solvency in the small open economy of Australia. Results indicate that in the fixed exchangerate era exports and imports are multicointegrated while in the more recent floating exchange-rate period the series do not share a conventional long-run equilibrium relationship. The results are consistent with intertemporal external solvency in the early period and insolvency more recently. Sustainability criteria are reviewed. Indications are that low saving and investment rates may inhibit Australia's abiliry to sustain persistent external imbalances, however, recent fiscal adjustments may work to abate this problem.     

对中国国际贸易与FDI相互关系的重新检验

This paper studies the long-term relationship between FDI and imports and exports through evidence from China by using cointegration technology, and the Granger causality test shows that FDI had an obvious effect on imports and exports activities of foreign firms, and in the meantime, the imports and exports of foreign firms greatly promoted FDI. However, there is not a stable equilibrium between FDI and international trade in the long run for all firms in China. This paper provides some explanations for the possible reasons that cause the above difference in estimation results from the perspectives of both location and industry factors.      

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.

     

Is there an export or import-led productivity growth in rapidly developing Asian countries? a multivariate VAR analysis

In contrast to cross-country studies, the paper investigates the relationships between trade and labour productivity for nine rapidly developing Asian countries in a time-series framework using a vector error-correction model. Independent tests on the long-run and short-run relationship between trade variables of exports and imports and productivity are conducted. The results suggest that trade has an important impact on productivity and output growth in the economy, however it is imports that provide the important?‘virtuous’?link between trade and output growth. The results indicate that exports and imports have qualitatively different impacts on labour productivity. The long-run result shows that there is no causal effect from exports to labour productivity growth for Hong Kong, Indonesia, Japan, Taiwan and Thailand; thereby suggesting that there is no export-led productivity growth in these countries. However, significant causal effects were found from imports to productivity growth, suggesting import-led productivity growth in India, Indonesia, Malaysia, Philippines, Singapore and Taiwan. In addition, the results indicate that imports tend to have greater positive impact on productivity growth in the long run.     

Taiwan's exports and trade imbalance against US and Japan: an empirical investigation based on error correction model

This study employs recent advances in time-series analysis, cointegration and error correction model, to examine the long-run and short-run determinants of the exports and trade imbalance between the USA, Japan, and Taiwan. The unit root tests reveal nonstationary in most of the variables. The cointegration tests affirm positive the long-run associations are between the exchange rate changes and the exports as well as the trade imbalance. Once these long-run effects are accounted for, it is found that there are evidences of short-run relationship between these variables.     

ANALYSIS OF THE CURRENT ACCOUNT POSITION OF FOUR ASIAN COUNTRIES BEFORE THE 1997 CRISIS

Abstract.  The current paper presents an empirical analysis of the current account positions during the pre Asian crisis period, in the four most crisis-hit countries (namely Thailand, the Philippines, South Korea and Indonesia). We have employed the procedures advocated by Husted for the presence of stationarity in current accounts by estimating a cointegration relationship between any country's exports and imports. The results do not substantiate the presence of cointegration between the series, implying that the macroeconomic fundamentals in these countries prior to the crisis were far from robust, at least from the perspective of current account sustainability.     

Export-led Growth and Import Compression: Further Time Series Evidence From LDCs

This paper conducts tests of the export-led growth and the import-compression hypotheses for four less developed countries (LDCs) – India, Nigeria, Fiji and Papua New Guinea (PNG). Based on Johansen's multiple cointegration test preceded by unit root tests, we test for cointegration between real output, exports and imports. Non-rejection of cointegration between the variables excludes the possibility of Granger non-causality and suggests at least one way Granger causality. Real output, exports and imports are found to be cointegrated in two of the countries and the resulting error-correction models suggest that Granger causality runs from exports and imports to real output in these cases. Exogeneity tests are conducted for exports with respect to real output. However, while the assumption of weak exogeneity is validated in two of the countries, the null hypothesis of super exogeneity is rejected. The test results therefore cast doubts on policy recommendations for the LDCs based on the export-led growth hypothesis.     

Imports and exports in 50 countries: Tests of cointegration and structural breaks

This paper provides new evidence on the long-run convergence between imports and exports in 50 countries over the quarterly period 1973:2 to 1998:1. Cointegration analyses are based on the Johansen [Johansen, S. (1995). Likelihood-based inference in cointegrating vector autoregressive models. New York: Oxford University Press.] and the Stock and Watson [J. Am. Stat. Assoc. 83 (1988) 1097.] system approaches. Evidence of stability of the cointegration space is examined using the SupF test developed by Hansen [J. Bus. Econ. Stat. 10 (1992) 321]. Based on the Johansen technique, we find evidence in favor of cointegration in 35 of the 50 countries. In addition, cointegration is confirmed for all countries (except Mexico) using the Stock and Watson test. This finding indicates that macroeconomic policies have been effective in the long-run and suggests that these countries are largely not in violation of their international budget constraint. We find evidence that in most of the countries where the slope coefficient on the export variable is positive, the cointegrating coefficient is also unity. The cointegration space appears stable for most of the countries. Nonetheless, the results suggest that countries in the regions of the Middle East, Latin America, and Europe have cointegrating relations that are more unstable than those in other regions.     

ON EXPORT-LED GROWTH IN AUSTRALIA AND CANADA: COINTEGRATION, CAUSALITY AND STRUCTURAL STABILITY*

This paper uses cointegration and vector-error correction (VEC) modelling to investigate whether the export-led growth hypothesis applies to Australian and Canadian exports and labour productivity. The Johansen (1988) procedure is used to test whether manufacturing and aggregate measures of exports and labour productivity are cointegrated. Exports and labour productivity are found to be cointegrated, suggesting the export-led growth hypothesis holds for the small, open Australian and Canadian economies, although the estimated cointegrating vectors suggest the relationship is of small order. The tests suggested in Hansesn (1992), for parameter stability in relationships with I(1) variables, are estimated to examine if the parameters estimated from the Johansen procedure are unstable and whether the null of cointegration can be rejected in favour of structural change. No evidence is found of parameter instability in either the Australian or Canadian long-run relationships at conventional significance levels. Estimation of VEC models suggests that exports are seen to cause productivity growth, although the quantitative impacts are again small. The reverse causality is rejected for both countries, except for the Canadian manufacturing sector for which there is a small, significant positive effect of labour productivity on manufactured exports.     

Are imports and remittances cointegrated for the Central and Eastern European countries?

In this article, we investigate the existence of long-run common trends between imports and remittances in 11 Central and Eastern European countries which are part of the European Union. Using the Engle–Granger two-step procedure, we determine that for all countries in our sample there are no long-run common trends (no cointegration) between imports and remittances. However, the results are mixed when running a Granger causality test. For nine countries, we can establish either a bidirectional or unidirectional Granger causality, indicating that past values of one variable have predictive content on the other variable. In two countries, there is no Granger causality between imports and remittances.     

An Empirical Analysis of Short-run and Long-run Irish Export Functions: Does exchange rate volatility matter?

We analyse the long-run and short-run relationship between merchandise export volume and its determinants, foreign income, relative prices and exchange rate volatility, using the techniques of cointegration and error correction. The model was estimated for Irish exports and sectoral exports SITC 0-4 and SITC 5-8 to the EU using quarterly data for the period 1978-1998. The sectoral classification corresponds to the exports of mainly indigenous Irish firms and multinationals, respectively. We find that the exchange rate volatility has no effect on the volume of trade in the short-run but a significant positive effect in the long run. This is true in the aggregate and for our sectoral classifications. We can tentatively conclude that the decline in intra-EU exchange rate volatility associated with the single currency will lead to a long-run fall in Irish exports to the EU.
