We derive the parameter restrictions that a standard equity market model implies for a bivariate vector autoregression for stock prices and dividends, and we show how to test these restrictions using likelihood ratio tests. The restrictions, which imply that stock returns are unpredictable, are...

Empirical analyses of Cagan?s money demand schedule for hyper-inflation have largely ignored the explosive nature of hyper-inflationary data. It is argued that this contributes to an (i) inability to model the data to the end of the hyper-inflation, and to (ii) discrepancies between ?estimated?...

A vector autoregressive model allowing for unit roots as well as explosive characteristic roots is developed. The Granger-Johansen representation shows that this results in processes with two common features: a random walk and an explosively growing process. Co-integrating and co-explosive...

Empirical analyses of Cagan`s money demand schedule have broadly speaking suffered from the following problems: (i) Inability to model the data to the end of the hyperinflation. (ii) Difficulties in making congruent models for systems of variables. (iii) Discrepancies between estimated and...
