... be viewed as exogenous or endogenous. Design/methodology/approach We use the Karakaplan and Kutlu (2017) endogenous stochastic frontier model, which allows us to account for the endogeneity of institutional quality and assess whether greater institutional quality reduces aggregate inefficiency...

... an improved version of the stochastic frontier model proposed by Karakaplan (2018), which can control the problem of endogeneity. Third, in quantifying the determinants of trade efficiency, the authors apply a system GMM estimator, which allows us to overcome the problems of endogeneity, measurement errors...

...Yongseung Han; Thomas Littlefield; Myeong Hwan Kim Purpose This paper proposes the use of a gauge function as a measure of technical efficiency. The measure of technical inefficiency from a gauge function is desirable as the estimation of a gauge function is not subject to the endogeneity problem...
