We examine the use of the random walk hypothesis on the BRICS stock indices. Our examination of the stock indices uses a recently developed wavelet-based unit root test by Fan and Gençay (2010) along with a battery of unit root tests. We also examine the sensitivity of the wavelet-based unit...

In this paper, we explore linear and nonlinear Granger causalities between oil price and the real effective exchange rate of the Indian currency, known as ‘rupee’. First, we apply the standard time domain approach, but fail to find any causal relationship. So, we decompose the two series at...

The purpose of the paper is to revisit the inflation–output gap relationship using a new approach known as the wavelet transform. This approach combines the classical time series analysis with frequency domain analysis and presents the advantages of assessing the co-movement of the two series...

This article examines the existence and stability of the consumption function in the United States of America (US) beginning in the 1950s. In order to obtain a stable long run relationship, we have introduced two innovative elements into the analysis of the life-cycle of the consumption function...

This paper estimates the steady state growth rates for the main European countries with an extended version of the Solow (1956) growth model. Total factor productivity is assumed a function of human capital, trade openness and investment ratio. We show that these factors, with some differences,...

We investigate the growth enhancing variables in a group of countries belonging to the same geographical area namely, India, Sri Lanka, Pakistan and Bangladesh over the period 1960–2010. We find that this “homogeneity” does not necessarily imply that countries have the same growth...
