Granger causality is becoming an important tool for determining causal relations between neurobiological time series. For multivariate data, there is often the need to examine causal relations between two blocks of time series, where each block could represent a brain region of interest. Two alternative methods are available. In the pairwise method, bivariate autoregressive models are fit to al...

The present study investigates the cointegration relationships among crude oil price, domestic gold price and selected financial variables (exchange rates and stock price indices) in India. Increasing crude oil prices will increase the production costs which will affect cash flow and will decrease stock prices. Investors are showing fewer concerns in the stock markets and investing in yellow me...

The paper examines the causal nexus between financial development, economic growth and poverty reduction in India during 1951-2008. The empirical analysis is based on cointegration and causality test. The cointegration test finds the presence of long run equilibrium relationship between financial development, economic growth and poverty reduction. The Granger causality test at the end confirms ...

We provide a structural approach to disentangle Granger versus instantaneous causality effects from transaction durations to transaction prices. So far, in the literature, instantaneous causality effects have either been excluded or cannot be identified separately from Granger type causality effects. By giving explicit moment conditions for observed returns over (random) transaction duration in...

The present paper is aimed at studying the nature of the causal relationship between stock prices and macroeconomic variables in India, if any such relationship exists. For this purpose the techniques of unit– root tests, cointegration and the Granger causality test have been applied between the NSE Index ‘Nifty’ and the macroeconomic variables, viz., Real effective economic rate (REER), Foreig...

Recent developments in the Bulgarian economy bring into question the validity of the twin deficit hypothesis. This paper analyses the theoretical foundations of and alternative explanations for this hypothesis and uses different econometric approaches to test its validity on a sample of the Bulgarian data. A Granger causality test suggests the existence of dual causality between the fiscal and ...
