H. Beladi et al., RATIONAL AND ADAPTIVE EXPECTATIONS IN THE PRESENT VALUE MODEL OF HYPERINFLATION, Review of economics and statistics, 75(3), 1993, pp. 511-514
We apply Chow's (1989) technique to the present value model of hyperin
flation under rational and adaptive expectation hypotheses. We use the
monthly data on price and money supply of Germany (1921:5-1923:8), Hu
ngary (1921:10-1924:2) and Poland (1922:1-1924:1). Our test results sh
ow that the German data are consistent with the adaptive expectations
hypothesis and the Hungarian data are consistent with the rational exp
ectations hypothesis. The Polish data, however, do not support either
of the two hypotheses.
