Tests of Causality, Predeterminedness and Exogeneity

International Economic Review, 1983
Consider a linear dynamic simultaneous equations model containing two time series \(x_ t\) and \(y_ t:\) \[ \begin{pmatrix} a(L) & b(L) \\ c(L) & d(L) \end{pmatrix} \binom{x_ t}{y_ t} = \binom{u_ t}{v_ t} \] where L is the lag operator defined by \(L^ jx_ t=x_{t-j}\), \(a(L)=\sum^{\infty}_{j=0}a_ jL^ j\) and \(a_ j\) are scalar constants.

Testing for Granger's Full Causality

The Review of Economics and Statistics, 1992
A procedure is proposed to test for the existence of a fully causal relationship between two variables. The method involves contrasting the probabilistic forecasting performance of a univariate and bivariate specification for the same variable Y. If there exists some theory or belief that X causes Y, and the addition of a variable X to the information ...
