dc.description.abstractThis paper is concerned with univariate noncausal autoregressive models and their potential usefulness in economic applications. We argue that noncausal autoregres- sive models are especially well suited for modeling expectations. Unlike conventional causal autoregressive models, they explicitly show how the considered economic vari- able is affected by expectations and how expectations are formed. Noncausal autore- gressive models can also be used to examine the related issue of backward-looking or forward-looking dynamics of an economic variable. We show in the paper how the parameters of a noncausal autoregressive model can be estimated by the method of maximum likelihood and how related test procedures can be obtained. Because noncausal autoregressive models cannot be distinguished from conventional causal autoregressive models by second order properties or Gaussian likelihood, a detailed discussion on their speci cation is provided. Motivated by economic applications we explicitly use a forward-looking autoregressive polynomial in the formulation of the model. This is different from the practice used in previous statistics literature on noncausal autoregressions and, in addition to its economic motivation, it is also convenient from a statistical point of view. In particular, it facilitates obtaining like- lihood based diagnostic tests for the speci ed orders of the backward-looking and forward-looking autoregressive polynomials. Such test procedures are not only useful in the speci cation of the model but also in testing economically interesting hypothe- ses such as whether the considered variable only exhibits forward-looking behavior. As an empirical application, we consider modeling the U.S. in ation dynamics which, according to our results, is purely forward-looking.en
