There is a growing literature on unit root testing in threshold autoregressive models. This paper makes two contributions to the literature. First, an asymptotic theory is developed for unit root testing in a threshold autoregression, in which the errors are allowed to be dependent and...

In this paper, we develop exact inference procedures (tests and confidence region)\ for autoregressive models [AR($p$), $p\geq 1$]. Proposed approaches test hypotheses, which fix the complete vector of autoregressive coefficients with Fisher-type statistics. Distribution of each statistic is...

In this paper, I develop a quasi empirical likelihood estimator that has good finite-sample properties when there are many moment conditions. I show that the quasi empirical likelihood estimator, which uses semiparametric efficient estimation, is an approximation to the empirical likelihood...

Estimators based on moment conditions of the form E[g(X,t)], where t is a finite-dimensional parameter vector of interest, are a popular tool in applied econometrics. Unlike likelihood-based estimators, moment-based estimators do not require the researcher to specify the probability distribution...
