The Balance of Payments Constraint and the Post 1973 Slowdown of Economic Growth in the G7 Economies

This paper presents estimates of export and import demand functions for the G7 economies over the period 1956 to 1995 and over two sub-periods 1956-73 and 1974-95. These estimates are used to construct predictions of the equilibrium growth rates for these economies by use of the 'Thirlwall's Law' relationship. The estimates are consistent with observed cross country growth patterns over the whole sample and the post 1973 period but are less convincing in the pre 1973 sub-period. It is argued that the slowdown in economic growth after 1973 can be partly explained by the growing internationalisation of the world economy coupled with a slowdown in the overall growth of world trade.     

‘Thirlwall's Law’ and balance of payments constrained growth: more on the debate

The various criticisms that have levelled against Thirlwall's Law by McGregor and Swales are examined. It is shown that their arguments are untenable. The relationship between the necolassical law of one price and Thirlwall's Law is clarified. Thirlwall's Law is not overwhelmingly rejected by the evidence as McGregor and Swales assert. Their suppression of the influence of the price term on the estimates used in the test proposed by McCombie is inappropriate. Their regression analyis is also mid-specified and a preferable specification provides no support for their conclusions. They repeatedly argue that Thirlwall's modele cannot account for changes in market shares and the that the estimated income elasticities of demand for exports and imports cannot capture the effects of non-price competition. This was shown to be erroneous by McCombie and the reasons advanced are further elaborated. McGregor and Swales provide another interpretation of the relationship between Thirlwll's Law and the Harrod foreign trade multiplier, But their criticism of McCombie is unwarranted. The methodology of McGregor and Swales seems to be one of ‘naive falsificationism’.     

Thirlwall’s Law and the Stability of Export and Import Income Elasticities

The aim of this paper is to examine the stability of income elasticities used in Thirlwall's law to approximate a country's long-term growth and to see empirically how non-constancy will affect these predictions. For this purpose, three countries - Canada, New Zealand and the UK - are analysed, using annual time series data from 1973 to 1995. These three countries were chosen on the basis of their contrasting trade patterns. The results obtained are different for each country but they still suggest the predictive power of one of the two specifications of Thirlwall's law is good.     

Balance-of-payments constrained growth model for the Turkish economy

Economists have investigated the relationship between output and export in order to explain economic growth for long years. Numerous studies have found very close correspondence between the growth of output and export. It is commonly known that Thirlwall's papers indicate very tight relationship between the growth of output and the ratio of the growth of exports to the income elasticity of demand for imports. This paper aims to apply Thirlwall's balance-of-payments-constrained (BPC) model for the Turkish economy for 1968–2011 period. This research also evaluates the procedures of testing Thirlwall's principle by estimation of the income elasticity of demand for imports using the test of stationarity and cointegration methods. The findings are in accordance with the Harrod–Thirlwall growth model. The test results of Johansen cointegration procedure and the comments on these results are presented as well.     

Modelling economic growth with internal and external imbalances: Empirical evidence from Portugal

Thirlwall's Law considers that growth can be constrained by the balance-of-payments when the current account is in permanent deficit. The Law focuses on external imbalances as impediments to growth and does not consider the case where internal imbalances (budget deficits or public debt) can also constrain growth. The recent European public debt crisis shows that when internal imbalances are out of control they can constrain growth and domestic demand in a severe way. The aim of this paper is to fill this gap by developing a growth model in line with Thirlwall's Law that takes into account both internal and external imbalances. The model is tested for Portugal which recently fell into a public debt crisis with serious negative consequences on growth. The empirical analysis shows that the growth rate in Portugal is in fact balance-of-payments constrained and the main drawback is the high import elasticity of the components of demand and in particular that of exports.     

Distributive cycles and endogenous technical change in a BoPC growth model

Our purpose in this paper is to expand Goodwin's (1967) distributive cycle model to an open economy framework in a way that incorporates the balance-of-payments constraint on growth. We do so by allowing technical change to be endogenous to the cyclical dynamics of the system and by adopting an independent investment function. We show that a Hopf-Bifurcation analysis establishes the possibility of persistent and bounded cyclical paths both for a 3D and a 4D extension of the model. Some numerical simulations are performed based on the analytical models developed. Motivational empirical evidence is also provided for Thirlwall's law using a sample of 16 OECD countries.     

A 'Generalised' Version of the Balance-of-Payments Growth Model: An application to neighbouring regions

This paper applies a 'generalised' version of Thirlwall's balance-of-payments (BOP) constrained growth model by testing for long-run relationships between the output growth rates of OECD countries and two neighbouring regions; South Africa (SA) and the rest of the Southern African Development Community (RSADC). The empirical results find strong support for the 'generalised' BOP growth model, which stresses the mutual interdependence of the world economy where one country's growth rate depends on others'. Although the policy implications are not mutually exclusive, they may be viewed from the individual perspectives of SA and RSADC. SA is only BOP constrained with respect to OECD. The message to SA's policy makers is that faster growth rates may be the result of an improvement in the structural demand features of its exports to OECD. RSADC is only BOP constrained with respect to SA. Growth-promoting policies in SA may have a high and positive impact on the whole SADC region. Policy-makers in RSADC, however, are advised to reduce their dependence on SA by improving the structural demand features of their exports to OECD.     

Unemployment and output dynamics in CIS countries: Okun’s law revisited

Okun’s law is a well-known relationship between the change in the unemployment rate and output growth. The main objective of this article is to provide a rigorous econometric analysis of Okun’s law for several CIS countries using different models and theoretically justified econometric methods. The traditional approach to Okun’s law estimation using OLS regressions does not account for possible endogeneity of regressors and the implied inconsistency of the estimates obtained. These problems point out to incorrectness of applications of the standard OLS estimation techniques. Our study addresses these issues by using econometrically justified instrumental variable regression methods. The article provides the results and discussions on practical use of Okun’s relationships for evaluation of average effects of economic growth on the unemployment rate, and vice versa; importance of accounting for confidence intervals in applications of Okun’s models to economic development analysis and cross-country comparisons and evaluation of effects of crises and other structural shocks on the economies considered. We also discuss in detail the results of formal econometric tests and economic motivation for validity of instrumental variables used in the study. The formal econometric tests, together with economic arguments, allow us to determine the most appropriate Okun-type models for each of the CIS countries under consideration.     

The black market exchange rate and demand for money in sixteen developing countries

Using data for a sample of 16 diverse countries, this study tests the hypothesis that it is the black market exchange rate, not the official rate, that should enter into the demand for money function of countries where there is a black market for foreign currencies. Using several cointegration methods and Hausman tests, it is shown that this hypothesis is strongly supported for most of the countries studied.     

Does monetary policy credibility mitigate the fear of floating?

Based on the argument that monetary policy credibility can reduce the fear of floating, we analyze this hypothesis for a set of 47 countries (of which, 32 are developing countries, 26 are Inflation Targeting countries and 16 are Inflation Targeting developing countries). Our study is the first to empirically assess the impact of monetary policy credibility (defined as the central bank's ability to anchor inflation expectations to the target) on the central banks' reaction through the basic interest rate due to exchange rate fluctuations (fear of floating). Based on panel data methodology applied to different samples, the most important result of this paper is that monetary policy credibility is able to mitigate the fear of floating. However, this effect is weaker after the crisis. Our estimates also reveal that Inflation Targeting developing countries present stronger fear of floating, which is justified by the fear of inflation in these countries.     

Import demand in heterogeneous panel setting

To study the elasticities of import demand function, a heterogeneous panel is built with data of 40 countries and using panel unit root tests (Im et al., 1997) and panel cointegration tests (Pedroni, 2004). The model is tested with two previously used activity variables: GDP and GDP minus Export for a performance comparison. To estimate elasticities, use is made of two modified panel versions of FMOLS and DOLS developed by Pedroni (1996, 2000, 2001). The tests prove that GDP outperforms GDP minus Exports as an activity variable in the cointegration context. FMOLS and DOLS give close results when individual estimates are done. When between‐dimension estimators are used, conflicting results are obtained. Then, the sample is split into developed and developing countries and it is shown that income elasticity in developing countries are not different than unity on average and are higher than in developed countries contradicting previous literature results.     

The unbiasedness hypothesis in the forward foreign exchange market: A specification analysis with application to France,Italy, Japan,the United Kingdom and West Germany

The purpose of this paper is to carry out a specification analysis of a test relation for the unbiasedness hypothesis using thirty-day forward foreign exchange data from France, Italy, Japan, the United Kingdom, and West Germany. The results indicate that econometric problems do exist for each country's test equation over the entire sample. For each country, there is at least one period which admits a statistically adequate regression equation. Results for these periods show that the null hypothesis of the unbiasedness of the forward rate is rejected for some countries but is retained for others.     

The relationship between the inflation rate and its variability: the issues reconsidered

This paper empirically reexamines the hypothesis of a positive relationship between the inflation rate and its variability. The sample consists of 66 countries for the 1955–85 sample period. Using pooled cross-section time series data, empirical tests are performed for nine different country-groupings ranging from the G–7 developed countries to a group of 10 developing Asian countries. Several important conclusions can be derived. First, irrespective of the variability measure employed, the results indicate the presence of a significant positive relationship between the inflation rate and its variability. This provides strong support to Okun's hypothesis. Second, this relationship is stronger during the flexible rather than the fixed exchange rate period. Third, there appears to be an optimum zone of inflation rate within which the predictability of inflation is at its highest and hence uncertainty cost is at its lowest. For the 1955–85 sample period, this optimum zone of average inflation rate lies in the range of 5 to 7 percent.     

Evidence on inflation–output trade-off in developing and industrial countries

This paper subjects Lucas's output–inflation trade-off study to further empirical investigation. The cross-country study divides the 111 countries covered into 90 developing countries and 21 advanced countries. Lucas's proposition is that volatility of aggregate demand growth should reduce the impact of aggregate demand growth on the cyclical output and the implication of this is that there is no output–inflation trade-off in line with the natural rate theory. We employ annual data over periods that fall between 1958 and 1985 in order to conduct the test. Our findings suggest that Lucas's proposition is valid for developed economies but not for developing economies.     

A system of equations model of UK tourism demand in neighbouring countries

This paper uses a system of equations model to examine tourism demand during periods of destination country transition and integration into the wider international community. The Almost Ideal Demand System model is applied to the UK demand for tourism in the neighbouring destinations, France, Spain and Portugal. Spain and Portugal are interesting cases as, during the period under consideration, they experienced a process of transition from economies with characteristics typical of developing countries, only entering the World Bank's industrialized countries classification in the 1980s. The paper examines the evolution of tourism demand during these countries' transition from ‘developing’ to ‘developed’ status. Consideration of France as a neighbouring destination also allows the behaviour of tourism demand to be compared between relatively rich and poor countries. The results show the extent to which the cross-country behaviour of demand becomes more or less similar over time with respect to changes in expenditure and effective prices. The expenditure elasticities are greater for Spain than France during the initial period, indicating that tourism can assist countries to ‘catch-up’ with their richer neighbours. However, this outcome is not always the case and may not persist, as Portugal had a low initial expenditure elasticity and Spain's relatively high expenditure elasticity decreased over time. Destinations' sensitivity to changes in their own and competitors' prices can also change over time, as indicated by the increases in the own- and cross-price elasticities for Spain, compared with the decreases for France and Portugal. The cross-price elasticity estimates indicate substitutability between the immediate neighbours, Portugal and Spain, and France and Spain.     

Money demand, the Cagan model, testing rational expectations vs adaptive expectations: The case of Turkey

This paper estimates the Cagan type demand for money function for Turkish economy during the period 1986:1–1995:3 and tests whether Cagan's specification fits the Turkish data using an econometric technique assuming that forecasting errors are stationary. This paper also tests the hypothesis that monetary policy was implemented in aiming to maximize the inflation tax revenue. Finally, the Cagan model is estimated with the additional assumption of rational expectations for Turkey for the considered period.

The effects of parent company business on occupational credit union behaviour

The allocation of British bilateral foreign aid among developing countries is simultaneously modelled, focusing on allocations during the period 1980–87. Two aid allocation decisions are analysed using a variant of the Lee-Maddala econometric model. The first decision concerns the determination of developing country eligibility for aid, while the second concerns the amount of aid eligible countries are allocated. Given the implied two-part decision-making process, sample selection techniques are employed. It is hypothesized that British bilateral aid eligibility and amount decisions are based on Bristain's humanitarian, commercial and political interests in developing countries. Results obtained indicate that these decisions are generally consistent with each of these interests, especially those relating to the political importance of Commonwealth members.     

ESTIMATING IMPORT AND EXPORT DEMAND ELASTICITIES FOR MAURITIUS AND SOUTH AFRICA

In this paper, we re‐estimate the import and the export demand functions for Mauritius and South Africa using time series data. We use the bounds tests for cointegration and find evidence of a long‐run relationship between import demand, income and prices for both countries. Our long run elasticities reveal that domestic income and relative prices have significant effects on the import demand for both countries, with income being the most important determinant. Furthermore, we find that while South Africa's export demand is not responsive to relative prices or income; for Mauritius income is statistically significant.     

How Do Technical Barriers to Trade Influence Trade?

This paper empirically estimates the trade effects of technical barriers to trade (TBT) based on all TBT notifications from 105 World Trade Organization (WTO) countries during 1995–2008. The paper adopts a modified two‐stage gravity model to control for both sample selection bias and firm heterogeneity bias. It was found that a country's TBT notifications decrease other countries' probability of exporting, but increase their export volumes. The result can be explained by the TBT's differential effects on the fixed and variable cost of export, and consumer confidence. It was further found that (i) a developing country's TBT have significant effects on other developing countries' exports, but no significant effects on the developed countries' exports, (ii) a developed country's TBT have significant effects on the exports from both types of countries, and (iii) exports from developed countries are affected by a developed country's TBT more seriously than a developing country's TBT.     

Productivity Growth And Market Structure In Telecommunications

This study examines sources of telecommunications sector productivity growth. Total factor productivity (TFP) growth is calculated using the Malmquist productivity index for a sample of 74 countries for the period 1991 through 1995. An econometric model is estimated which relates TFP growth to output growth, network digitisation, telecommunications development, output-mix, the business cycle and market structure. Model estimates suggest that higher digitisation rates dampen TFP growth in the short run, and cross-subsidisation of services creates inefficiency. However, developing countries can increase TFP growth through catch up, and increased privatisation and competition are conducive to productivity growth.
