Abstract
The present paper considers the testing of unit root hypothesis for an autoregressive model with polynomial trend under Bayesian framework. Under the unit root hypothesis the trend component does not vanish completely and its degree reduces by one. The posterior odds ratio for the unit root hypothesis has been derived under appropriate prior assumptions for the parameters of the model.
