Abstract
A regression model with deterministic frontier is considered. This type of model has hardly been studied, partly owing to the difficulty in the application of maximum likelihood estimation since this is a non-regular model. As an alternative, the Bayesian methodology is proposed and analysed. Through the Gibbs algorithm, the inference of the parameters of the model and of the individual efficiencies are relatively straightforward. The results of the simulations indicate that the utilized method performs reasonably well.

Notes
The parameter \(\gamma \) mentioned is the proportion of the total variance of the composite error due to inefficiency. Therefore, if it is estimated to be 1, then the whole error is inefficiency, that is to say, the model does not have random noise and its frontier is deterministic.
