The defense‐growth nexus is investigated empirically using time series data for the US and allowing the effect of defense spending on growth to be non‐linear. Using recently developed econometric methods involving threshold regressions, evidence of a level‐dependent effect of military expenditure on GDP growth is found: the positive externality effect of defense spending prevails for relatively lower levels of defense spending (with respect to the history of defense spending in the US) and reverts its influence for higher levels.  相似文献

This study revisits the relationship between defence spending and economic growth via a Keynesian model in Pakistan using the autoregressive distributive lag bounds testing approach to cointegration. Empirical evidence suggests a stable cointegration relationship between defence spending and economic growth. An increase in defence spending reduces the pace of economic growth confirming the validity of Keynesian hypothesis in this case. Current economic growth is positively linked with economic growth of previous periods while a rise in non-military expenditures boosts economic growth. Interest rate is inversely associated with economic growth. Finally, unidirectional causality running from military spending to economic growth is found.  相似文献

The purpose of this paper is to investigate regional effects of military base closures in Sweden during the last decades. Our analysis is based on a regional growth model, where two equations are estimated; one equation describing the average income growth rate and one equation describing the net migration rate. The data set is a panel of 31 Swedish municipalities covering the period 1983–1998. Our main finding is that a closure of a military base has not had any significant impact on the subsequent average income growth rate nor the net migration rate in the affected municipalities. One potential explanation for these results relates to the labour market and the composition of the labour force.  相似文献

Using the Solow–Swan growth model and the time‐trend included in the aggregate production function, this study applies the multivariate cointegration approach to re‐investigate the long‐run and causal relationships between defence expenditures and GDP while controlling for capital and labour input in Taiwan during the 1955–2002 period. It examines the long‐run causal relationship using the weak exogeneity test and utilizes general impulse response functions to determine whether a shock to defence expenditures affects economic growth or vice versa. Our findings provide substantive evidence in favour of the existence of a long‐run equilibrium cointegrated relationship between defence expenditures, GDP, labour and capital stock. The results of the weak exogeneity test indicate that a bi‐directional causal relationship exists in the long‐run between defence expenditures and GDP. Thus, the main policy implication that emerges from the long‐run results is that increasing defence expenditures in Taiwan is an effective means to boost overall economic performance and, with this improved economy, it should then be able to increase its defence expenditures further. Lastly, from our dynamic vector error correction model estimations, it is found that defence expenditures are a major means of adjusting for disequilibria that occur within the system.  相似文献

The causal relationship between economic growth and defence spending has attracted considerable attention and has been the subject of many empirical studies. This paper investigates the existence of a causal link between military expenditure and economic growth in the case of Greece for the period 1955–93. By European Union standards, Greece allocates substantial human and material resources to defence. At the same time, Greece is the poorest European Union member facing chronic economic problems. Using the concept of Granger‐causality, the findings reported herein suggest that neither variable Granger‐causes the other disclosing thereof the absence of any causal ordering between them.  相似文献

There are a number of studies which consider the relation between military spending and economic growth using Granger causality techniques rather than a well‐defined economic model. Some have used samples of groups of countries, finding no consistent results. Others have focused on case studies of individual countries, which has the advantage of the researchers bringing to bear much more data than the cross country samples and a greater knowledge of the structure of the economy and the budget. This paper adds to the literature by providing an analysis of two countries, Greece and Turkey, which are particularly interesting case studies given their high military burdens, the poor relations between the two and the resulting arms race in the area. In addition to analysing the data using standard “pre‐cointegration” Granger causality techniques, this paper employs modern vector autoregressive (VAR) methodology that utilises cointegration via Granger's representation theorem. The standard Granger causality tests suggest a positive effect of changing military burden on growth for Greece, but this is not sustained when the cointegration between output and military burden is taken into account. The only evidence of significant Granger causality is a negative impact of military burden on growth in Turkey.  相似文献

This empirical note re-examines the causal linkages between military expenditures and economic growth for the BRICS countries (Brazil, Russia, India, China, and South Africa) and that for the USA during the period 1988–2012. Results of Granger causality tests show that military expenditures influence economic growth in the USA, economic growth influences military expenditures in both Brazil and India, a feedback between military expenditures and economic growth in Russia, and no causal relation exists between military expenditures and economic growth in China and South Africa. The findings of this study can provide important policy implications for the BRICS countries and also for the USA.  相似文献

This study contributes to the literature on political instability and economic growth by specifically investigating the impact of political instability on the economic growth of member countries of the Economic Community of West African States (ECOWAS). West Africa is regarded as the riskiest sub-region within the African continent. To achieve this objective, this study employed panel data techniques (fixed effects and generalised method of moments) on a sample of 15 ECOWAS member countries for the period 2005–2012. The findings from the analyses showed that terrorism, poor governance, social unrest, youth unemployment, death rate and natural resource rent have negative relationships with economic growth. The findings and policy implications deduced from this study could not have been any timelier considering the recent escalation of instability in West African countries and their fragile growth prospects.  相似文献
