| Summary/Abstract |
There is much controversy in the literature over whether military expenditures have a positive, negative or no relation impact on economic growth. The aim of this paper is to determine the relationship between GDP and defence expenditure. The study analyses GDP and defence expenditures of the developed countries with cross-sectional ADF and SURADF unit root tests using annual data for the years 1980-2007. We conclude that in the long term, according to the Pedroni cointegration test, there exists a relationship between defence expenditure and economic growth. Furthermore, by utilizing the Granger causality test, we find that defence expenditure is a factor in economic growth. In other words, our study validates the hypothesis that defence spending by economically developed countries positively contributes to their economics.

| Summary/Abstract |
Over the years, researches have witnessed incongruence nature and direction of relationship among product market competition and firm size with the growth of firms’ productivity across the globe. Considering these gaps, this study aims to establish both short- and long-run relationships among these three characteristics of Indian manufacturing firms and intends to find their directions of causalities. This study uses firm-level data over a period of 1998–1999 to 2012–2013. Using Panel ARDL-PMG method, the results reveal the existence of a long-run association among product market competition, firm size and productivity growth for the full sample and for subsamples, categorizing relatively efficient and inefficient firms, and innovative and non-innovative firms. From the panel VECM Granger causality test, it has been observed that there is the long-run feedback relationship among these three variables. The empirical evidence suggests that as the intensity of competition becomes stronger and the firm-specific capabilities expand, they impart improved productivity via within and between firm effects. This draws some major implications for policymakers to embrace more competitive prone policies along with encouragement to firm specificities to realise value-added productivity.

| Summary/Abstract |
We apply the lag-augmented vector autoregression technique to test the Granger-causal relationships among wholesale electricity prices, natural gas prices, and crude oil prices. In addition, by adopting a cross-correlation function approach, we test not only the causality in mean but also the causality in variance between the variables. The results of tests using both techniques show that gas prices Granger-cause electricity prices in mean. We find no Granger-causality in variance among these variables.
