Unobserved Rational Expectations and the German Hyperinflation with Endogenous Money Supply
使用卡尔曼滤波技术检验德国恶性通货膨胀中的收敛预期假说，在货币供给内生的情况下，通过参数和非参数检验拒绝了收敛预期的零假设。
A Kalman filtering technique is employed to test the convergent expectation hypothesis in the great German hyperinflation when the money supply is endogenously determined. After converting the model structure to a state space form, the parameters are estimated via minimization of a Gaussian likelihood function. The result is then used in a filter- smoother combination to yield smoothed estimates of the state variable associated with the arbitrary constant of the rational expectations solution. Bo th para-metric and nonparametric tests lead us to reject the null hypothesis of convergent expectations.
