Saving,investment and capital mobility in EU member countries: a panel data analysis of the Feldstein–Horioka puzzle

ABSTRACT

In this paper, we reexamine the long-standing and puzzling correlation between national saving and investment in 14 European Union (EU) countries. We employ a panel data set for the period 1970–2015 and we apply recently developed maximum likelihood panel cointegration methodologies. We find that there exists a long-run relationship between savings and investment for this panel of EU member countries, with the savings retention coefficient being low in magnitude but statistically different than zero. Therefore, we argue that there is weak evidence in favour of the Feldstein–Horioka puzzle and that the long-run international solvency condition is maintained in most of these countries. This evidence implies a moderate degree of capital mobility which is consistent with the macroeconomic experience of these countries during the period under investigation.     

Savings, Investment, Productivity and Economic Growth of Australia 1861–1990: Some Explorations

Policy makers' concerns over sub-optimal savings rates in Australia mistakenly concentrate on symptoms rather than causes of low rates of growth in investment and productivity. A growth model of a small open economy is used to demonstrate possible interdependencies of these variables which are tested using cointegration and long-run Granger causality techniques for the periods 1861–1900 and 1949–90. As expected, no direct long-run relationship is found between savings and investment. However the interactions between investment and productivity growth are found to be complex and evolving, whilst savings appear to be determined residually in the growth process.     

Investment and saving in Angola and the Feldstein–Horioka puzzle

This article analyses the relationship between investment and savings for Angola using the Feldstein–Horioka puzzle, with monthly data from January 2000 to December 2013. Integer and fractional integration and cointegration techniques are employed to investigate the relationship between investment and savings. Several regression specifications are employed, concluding that the Feldstein–Horioka puzzle is not validated for the Angolan economy. Policy implications are derived.     

The missing shock: the macroeconomic impact of British Privatizations

In this paper the impact of privatization on macroeconomic performance in the United Kingdom is tested using quarterly data from 1979 to 1999. Privatization proceeds have been included in a simple analytical framework dealing with both demand and supply-side of the economy. Multivariate cointegration techniques have been used in order to consider the nonstationarity of the time series involved. The empirical results show that privatizations have no long-run effects on output in the UK. This result is consistent with microeconomic evidence that shows that in the UK ownership change per se had little impact on long term productivity trends. Moreover it is found that privatization proceeds have contributed to sustaining public expenditures.     

Saving–investment Association and Regional Capital Mobility in China: A Nonparametric Panel Approach

Using a nonparametric panel data model, this paper estimates the degree of time‐varying and province‐specific capital mobility in China during 1970–2006. We estimate the savings–investment association, that is, the savings retention rate à la Feldstein and Horioka, as a measure of capital mobility. We also split the total savings (investment) into private and government savings (investment) to explore the role of government in improving capital mobility. Over time, we find an improvement in capital mobility after the mid‐1990s. Across provinces, we observe higher capital mobility in eastern/coastal regions. From the 1990s, the government is found to play a less important role in promoting capital mobility. Across provinces, the government is found to be more important in either the municipalities (Shanghai and Beijing) or the less developed inland provinces.     

Pooled Mean Group estimation on international capital mobility in African countries

This paper investigates the relationship between the savings and investment rates for 37 African countries over the period 1970-2006, using the recently developed Pooled Mean Group cointegration technique. Our results show that in the long-run, capital was relatively mobile in African countries, while, in the short-run, coefficients are not significant. However, there are marked differences in ratio retentions between country groups. The savings retention coefficient is higher in civil law countries than in common law countries. Furthermore, our results show that the Feldstein-Horioka coefficient is relatively lower in non-CFA than in CFA countries. These results have some policy implications.     

Do remittances and foreign aid augment the gross savings: Bangladesh,India and Philippines perspective?

Savings is considered to be a principal determinant to achieve long-run economic growth. Remittances and foreign aid are two important foreign capital inflows to meet the savings deficiency of developing nations. The objective of this study is to investigate the long-run impact of remittance to stimulate savings in remittance recipient countries. This paper contributes to the macroeconomic impact of remittance through a comparative study on Bangladesh, India and Philippines that positioned among the top ten largest remittance recipient countries from 2008 and onwards. The analysis makes use of an annual time series data over the period of 1980–2015. The Johansen cointegration test suggested long-run cointegrating relationship of remittance and foreign aid on gross savings. The test result suggests positive effect of remittances on gross savings for Bangladesh and Philippines although an insignificant negative effect for India. However, foreign aid has significant negative long-run impact in all the three cases. Government policy should focus on leveraging remittance flows to facilitate savings and investment for capital accumulation.     

Government Expenditures and Revenues: Evidence of Fractional Cointegration in an Asymmetric Modeling

In this paper, we examine the relationship between the US government expenditures and revenues using a fractional cointegration framework. In doing so, we permit a much richer degree of flexibility in the dynamic adjustment process toward equilibrium than in the classical case of cointegration. Moreover, we relax the assumption of a symmetric adjustment process throughout the use of threshold autoregressive (TAR) and momentum threshold autoregressive (M-TAR) models in the error correction representation of the process. The results show that both individual series are non-stationary I(1) and we do not find evidence of cointegration of any degree. However, if we take into account a structural break at 1973(2), fractional cointegration is found if the underlying process is autocorrelated, especially in the asymmetric modeling.

The savings-growth nexus for the Malaysian economy: a view through rolling sub-samples

The purpose of this study is to re-investigate the savings-growth nexus for the Malaysian economy using bounds testing approach to cointegration and Toda and Yamamoto (1995) and Dolado and Lütkepohl (1996) – TYDL Granger causality test. This study covered the sample period from 1971:Q1 to 2008:Q4. The cointegration results suggest that the variables are moving together in the long run and the TYDL Granger causality results indicate that the relationship between savings and economic growth is bilateral. In addition, the rolling sub-samples TYDL Granger causality test exhibited a relatively stable causal relationship running from savings to economic growth in Malaysia particularly before the onset of Asian Financial Crisis in 1997/1998.     

Consumption and disposable income in the EU countries: the role of wealth effects

We investigate the long run relationship between private consumption and disposable income for a sample of EU countries using recently developed panel cointegration techniques. For the ordinary consumption-income model the evidence on cointegration is ambiguous. In addition, the cointegration vector obtained by efficient estimation methods is not consistent with theoretical reasoning, as it reflects a decline in the savings rate over time. Extending the analysis by financial wealth improves the model fit markedly. In particular, the income elasticity is not different from 1 and therefore in line with the life cycle permanent income hypothesis. The marginal propensity to consume out of financial wealth is in a range of 3–5%, thereby confirming recent time series results.     

Addressing shortfalls in TIA care in the UK: an economic perspective

Abstract

Objective: To estimate the clinical outcomes and costs associated with reconfiguring the management of TIA in the UK to offer patients rapid access to outpatient clinics for specialist assessment and treatment.

Methods: An economic deterministic model was run comparing two pathways – one arm representing current clinical care based on national guidelines and clinical practice and patient referral to a weekly outpatient clinic, and a revised care pathway replicating phase 2 of the EXPRESS study with patient referral to a daily outpatient clinic. The outcomes of the model were measured in terms of recurrent strokes avoided and net budget impact to secondary care.

Results: Reconfiguring TIA care pathways in the UK could result in the avoidance of 8,164 recurrent stroke events. The model predicts savings of £25,573,279 for the UK healthcare system over 12 months. Annual net savings are predicted in England (£24,916,011), Scotland (£80,554) and Northern Ireland (£1,041,817). In Wales, increased costs of £450,435 are estimated.

Limitations: Using the data published from the EXPRESS study, it is not possible to model a stepwise approach to implementing the revised TIA care pathway. It is therefore assumed that it would be possible to implement the revised TIA care pathway as detailed in the EXPRESS study across the UK and achieve the reduction in recurrent stroke risk that was reported.

Conclusions: The model suggests that the reconfiguration of TIA care pathways in the UK to offer rapid access to treatment and assessment could prevent TIA-related future stroke events and potentially result in cost savings to the healthcare system.     

Investment opportunities in the source country and temporary migration

Abstract This paper examines how attractive investment opportunities available to temporary migrants at home affect their saving behaviour and the optimal duration of stay abroad. The model predicts an inverse U‐shaped relationship between migration duration and the expected rate of return on repatriated savings. A higher rate provides an incentive to go back earlier and consume less abroad, while it can also trigger emigration aimed at generating the savings required for investment after return. The paper illustrates how the behaviour of temporary migrants reflects the interaction between their preferences and the opportunities available in labour and capital markets of both countries.     

On the flow of funds accounts and inter-sectoral mobility of capital in India

This study uses the flow of funds accounts framework and undertakes an in-depth analysis of the inter-sectoral mobility of capital in India. Unlike previous studies, the FH model is estimated at the sectoral level using annual data for the period 1950–51 to 2012–13. The model estimated in one-regime setting with no structural break provides a weak and mixed support and that estimated in a sample-split setting with a single structural break provides no support for the presence of a long-run relationship between saving and investment for all the sectors. In contrast, the model estimated with multiple structural breaks provides dominant support for the presence of cointegration between saving and investment for all the sectors. The end-of-sample cointegration breakdown tests suggest the breakdowns of cointegration between saving and investment in all the sub-sample periods for the household and PCB sectors, but not for the public sector. The FOF accounts could be used to monitor the borrowing and lending operations of both financial and non-financial sectors and to identify any deformities in the system. The regulatory and supervisory policies need to be put in place promptly to resolve the identified deformities at their early stages, before they magnify and make the entire system dysfunctional.     

Trade and Investment Linkages and Stock Market Long‐Run Relationship

This paper aims to examine whether the intensity of trade and investment linkages among the countries matter for their stock market long‐run relationship. To achieve this, we classify Australia's bilateral trade and investment partners into major, medium and minor. Empirical findings of an asymmetric generalised dynamic conditional correlation generalised autoregressive conditional heteroskedasticity model show that correlations are time varying and increased significantly during the global financial crisis (GFC). Results of multivariate cointegration test confirm the long‐run equilibrium relationship between the stock markets of Australia and its major partners in the pre‐GFC and during GFC. Based on the full‐sample results, it indicates that the GFC has segmented the stock markets from the long‐run equilibrium relationship. Granger non‐causality test results on full sample show that Australian stock market causes only the New Zealand market while the USA, the UK, Germany, Canada, Switzerland and Italy drives the Australian market. Our results therefore suggest that the intensity of bilateral trade and investment linkages among the countries matter for their stock markets' long‐term relationship.     

Foreign Direct Investment Inflows and Economic Growth: The Case of Korea

The current study examines the relationship between FDI inflows and economic growth of Korea and tests the Bhagwati hypothesis which says that FDI inflow is more beneficial to economic growth in an open trade regime in a multivariate framework. Unlike previous works on the concerned hypothesis, a small‐sample cointegration test is applied to the time‐series data. There is no evidence of cointegration among the variables. The Granger causality test results show that, although FDI inflows do not cause per capita real GDP, the latter is revealed to cause the former when the economic crisis dummy variable is included. There is a unidirectional short‐run causality from domestic investment to per capita real GDP growth rate. The case of Korea does not support the Bhagwati hypothesis.     

Corporate Tax Incentives for R&D Investment in OECD Countries

Differentiating internal equity from debt finance, this study examines the generosity of R&D-specific tax incentives in OECD countries based on an NPV model. The corporate tax system generally favours debt finance and some previous findings on the possible preponderance of internal equity for financing R&D investment cannot be explained in relation to R&D-specific tax concessions. The OECD comparison demonstrates that R&D tax allowances adopted in the Czech Republic, Belgium, the UK, Denmark, Hungary, Austria and Australia generated the most substantial tax savings in 2006. Combined with such incentives, the after-tax NPV increases with the corporate tax rate, suggesting stronger investment stimulation through a tax-rate-increase-cum-base-broadening policy.     

A multivariate innovations state space Beveridge–Nelson decomposition

The Beveridge–Nelson vector innovations structural time series framework is a new formulation that decomposes a set of variables into their permanent and transitory components. The proposed framework is flexible, modelling inter-series relationships and common features in a simple manner. In particular, it is shown that this new specification is simpler than conventional state space and cointegration approaches. The approach is illustrated using a trivariate data set comprising the GDP of Australia, the USA and the UK.     

Regional growth and unemployment in the medium run: asymmetric cointegrated Okun’s Law for UK regions

This article tests for the presence of a medium-run asymmetric Okun’s Law relationship between regional output and regional unemployment rate in UK regions. The test is performed with a panel data version of the hidden cointegration technique suggested by Granger and Yoon. A novelty of the article is to combine the method of hidden cointegration with a panel data method of removing cross-sectional dependence. The medium-run Okun relationship for regions in the UK appears to confirm results found elsewhere in the literature on countries as a whole, although the coefficients tend to be smaller.     

Stochastic growth: a duality approach

We re-examine the representative agent's optimal consumption and savings under uncertainty in the presence of investment constraints using martingale representation and convex analysis techniques. This framework allows us to explicitly quantify precautionary savings which induces a higher average growth rate than in a certainty setup. We provide a closed form solution for a Cobb-Douglas economy. The effect of uncertainty on portfolio selection is analyzed. Consumption growth rate and risk free interest rate exhibit a U-shaped relationship. Uncertainty negatively affects expected consumption growth rate; such a result seems to be supported by empirical evidence.     

A revalidation of the savings–growth nexus in Pakistan

The aim of this study is to understand the relationship between savings and economic growth in Pakistan over the period 1971–2011. The cointegration and the Granger causality tests are adopted to examine the relationship between the variables. The results confirm the existence of long-run equilibrium among the variables of interest. Meanwhile, savings have positively affected economic growth in both the short run and long run. The Granger results also show that savings Granger-cause economic growth. Based upon these findings, we confirm that savings is a catalyst of growth for the Pakistani economy. Additionally, our results seem more likely to support the capital fundamentalists because the long run estimation as well as the Granger causality results also indicates that savings growth can effectively spur economic growth in Pakistan.
