This paper proposes a new testing procedure for the degree of fractional integration of a time series inspired on the unit root test of Dickey-Fuller (1979). The composite null hypothesis is that of d=d0 against d<d0. The test statistics is the same as in Dickey-Fuller test, exploiting the fact that if the process, under study, is I(d0) then the (-1+d0)th differenced series is I(1) under the null d=d0. If d>=d0, using the generalization of Sowell's results (1990), we propose a test based...</d0.>

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...

This study sheds new light on the question of whether or not sentiment surveys, and the expectations derived from them, are relevant to forecasting economic growth and stock returns, and whether they contain information that is orthogonal to macroeconomic and financial data. I examine 16...

This paper examines persistence in the Ukrainian stock market during the recent financial crisis. Using two different long memory approaches (R/S analysis and fractional integration) we show that this market is inefficient and the degree of persistence is not the same in different stages of the...

This article rejects the linkages in proposals that the Federal Reserve Bank (Fed) target equity prices. The real federal funds rate (RFF) and stock prices (SP) are uncorrelated; causality tests show a positive effect of SP on RFF and a negative effect of SP on RFF. These results occur as part of...

During the British Railway Mania of the 1840s the promotion and construction of new railways increased dramatically. These new projects were generally financed by shares with uncalled capital, which allowed investors to make payments on an instalment basis over a period of several years. There...
