This study shows that augmented Dickey-Fuller (ADF) test failed to detect covariance nonstationary series. Supportive of Ahamada (2004), this study finds that the cumulative sums of squares procedure in Inclán and Tiao (1994) is useful to complement the ADF test. As illustration, the ADF test...

The present paper puts forward a new hypothesis about the economic circuit, which is a product of Marx’s “period of production” and Keynes’s determination order between investment and savings. It leads to a new definition of profit which excludes any remaining competition between savings...

This paper deals with testing a time series with a structural break in its mean for a unit root when the break date is known. A nonlinear (with respect to coefficients) test equation is used, providing asymptotically efficient estimates. Finite-sample and quasi-asymptotic empirical distributions...

The preponderance of the linear approach in the stock market modeling is the result of the Frisch-Slutsky paradigm which implies that the market can only converge to an equilibrium point or diverge, according to a monotonic or oscillatory trajectory. Moreover, this description of reality is...

The Granger causality test is reduced, after co-integration, to the test of the fact that some coefficients of linear regressions are equal to zero or not. In this paper we will build multi-variate Bayes tests for the signification of the parameters of linear regression provided by the above...

The underlying nature of forecast optimization makes the rational expectations hypothesis (REH) a framework that is theoretically consistent with the expectations formation produced by economic agents under well-defined assumptions of unbiased forecasts and efficient utilization of available...

A new non-causality test based on the notion of distance between ARMA models is proposed in this paper. The advantage of this test is that it can be used in possible integrated and cointegrated systems, without pre-testing for unit roots and cointegration. The Monte Carlo experiments indicate...

This paper explores the response of the divorce rate to law reform introducing unilateral divorce after controlling for law reforms concerning the aftermath of divorce, which are omitted from most previous works. We introduce two main policy changes that have swept the U.S. since the late 1970s;...

After describing the various forms of efficiency and calendar anomalies observed in many developed and emerging markets according to the existing literature, the present study examines this phenomenon empirically in the Nepalese stock market for daily data of Nepal Stock Exchange Index from...

This article investigates whether the Nepalese stock market is efficient in weak form with respect to economically neutral behavioural variables. Simple OLS technique with White’s heteroskedasticity-corrected standard errors is used to test the relationship between stock returns and...
