Derivation of marginal effects of determinants of technical inefficiency

Kumbhakar, Subal C.; Sun, Kai - In: Economics Letters 120 (2013) 2, pp. 249-253

In efficiency studies using the stochastic frontier approach, the main focus is to explain inefficiency in terms of … some exogenous variables and computation of marginal effects of each of these determinants. Although inefficiency is … computed from the unconditional mean of inefficiency (Wang, 2002). In this paper we derive the marginal effects based on the …

Estimation of the threshold stochastic frontier model in the presence of an endogenous sample split variable

Lai, Hung-pin - In: Journal of Productivity Analysis 40 (2013) 2, pp. 227-237

Heterogeneity among firms has been an important issue in studying firms’ technical efficiencies. If firms do not randomly fall into different groups with different technologies but by self-selection, statistically it implies the data are subject to the sample selection bias. In this paper, we...

Pollution and economic growth: a maximum likelihood estimation of environmental Kuznets curve

Auci, Sabrina; Castelli, Annalisa - Volkswirtschaftliche Fakultät, … - 2011

As in Brock and Taylor (2011) in this paper we consider the importance of the relationship between the Environmental Kuznets Curve (EKC) Literature and the Economic Growth Theories. To address this issue we construct country production functions that directly incorporate CO2 emissions as input...

Measurement and Explanation of Technical Efficiency Performance in Ukrainian Agriculture, 1991-1996

Murova, Olga I.; Trueblood, Michael A.; Coble, Keith H. - In: Journal of Agricultural and Applied Economics 36 (2004) 01

The present study examines technical efficiency patterns in Ukraineâ€™s crop sector for 1991-1996. The economic and policy environment in Ukraine has changed since reform began in 1991. Many policy changes have exerted offsetting economic pressures on efficiency. Enterprise privatization...
