This paper considers the maximum likelihood estimation of a stochastic frontier production function with an interval outcome. We derive an analytical formula for calculating the likelihood function of the interval stochastic frontier models. Monte Carlo experiments reveal that the finite sample...

To insure a proper and meaningful productivity assessment of DMUs with different production technologies, this article develops a difference-based profit metafrontier Luenberger productivity indicator. Adopting the proposed model, we empirically measure the profit inefficiency and examine the...

In this paper we demonstrate that the measures of scale and scope economies may be elusive if failing to consider quality variation among universities and endogeneity of congestion in students learning and living facility utilization. Empirical results show that the private and highly congested...

This research develops a new group-based profit difference model for comparing profit performance at the group level with heterogeneous production technology and currencies. The proposed model can fully measure component effects that contribute to cross-group profit variation and also explicitly...

The purpose of this study is to empirically investigate Taiwanese married women's grocery shopping behavior in relation to their labor force participation status. In this study, focus is limited to their grocery shopping frequency which is meant to be a proxy for an input to household...

Factors which explain supply response behavior of South Carolina tomato growers were determined. Two well known supply response models were used for comparison: the Nerlovian structural model and the Just risk model. The Just risk model reflected the significance of the risk effect in both...

Membership of the Southern Agricultural Economics Association (SAEA) was polled to ascertain the strength of support for changing the name of the Southern Journal of Agricultural Economics (SJAE) to eliminate the regional connotation. The general view was that a name change is unwarranted. The...
