Estimating Money Demand for Ghana (Published)

The study suggested that money demand function for Ghana using M1 and M2 remained relatively unstable between 1991 and 2011 as evidenced by trends in recursive residual and the cumulative sums of squared residuals derived from the estimated models. However, real money demand function for broad money (M2+) was found to be stable relative to real money   demand functions estimated using for M1 and M2 as dependent variables. The study therefore concluded that real money demand function for M1 and M2 are remained relatively unstable in Ghana compared with real money demand function for broad money which exhibits some degree of stability.

THE STRUCTURE OF INDICES OF CONTROL SYSTEMS FOR CERTAIN SINGLE – DELAY AUTONOMOUS LINEAR SYSTEMS WITH PROBLEM INSTANCES (Published)

This paper investigated the structure of indices of control systems for single – delay autonomous linear systems on the interval [0, 4h] and on [0, ∞) for special coefficient matrix cases, as well as provided a note on Euclidean controllability and application instances of the determination of their controllability dispositions.

The development of the associated control index matrices exploited the continuity of these matrices for positive time periods, change of variables technique, the method of steps and backward continuation recursions to obtain these matrices on successive intervals of length equal to the delay h.

The indices were derived using the stage – wise algorithmic format, starting from the right – most interval of length h. The structure could be gleaned and deciphered from the emerged sign convention and recognizable exponential integral ordering.
