This paper provides a theoretically consistent approach to estimating demand relationships in which kink points occur either in the interior or on the vertices of the budget set. There are important classes of problems in developing countries which demonstrate such kinked budget sets including...

The specification and estimation of models of consumer and producer demand with kink points are considered. The presence of kink points divides the demand or production schedule into different regimes. Our approach utilizes the concept of virtual prices. The virtual prices transform binding...

This paper investigates the asymptotic distribution of the maximum likelihood estimator in a stochastic frontier function when the firms are all technically efficient. For such a situation the true parameter vector is on the boundary of the parameter space, and the scores are linearly dependent....
