33rd Academic Salon for Ph.D. Students in Theoretical Economics: Estimation of a Smooth-Coefficient Stochastic Production Function with Panel Data & Non- and Semi-parametric Methods
07.10.2017  Views:655   Author:ccsezr 

      June 26 saw the 5th Academic Salon for Ph.D. Students in Theoretical Economics in 2017 (the 33rd in history) held by the China Center for Special Economic Zone Research (CCSEZR), Shenzhen University (SZU) at Maoshuli Caf茅 near the West Gate of SZU. Prof. Yao Feng, an associate professor of Economics from the West Virginia University and a visiting professor at the CCSEZR, delivered an informative speech titled 鈥淓stimation of a Smooth-Coefficient Stochastic Production Function with Panel Data & Non- and Semi-parametric Methods鈥. The salon was presided over by CCSEZR associate professor Li Fan and attended by some teachers and graduate students from the CCSEZR and the College of Economics, SZU.

      Prof. Yao Feng brought in the theme of the salon 鈥渆fficiency鈥 with an example - improving dining efficiency. Technical efficiency denotes a firm鈥檚 ability to produce the maximum output from fixed inputs. If a firm鈥檚 effective technical efficiency is 1, it reaches full efficiency. Considering that the production possibility curve of a fully efficient firm is defined as the production possibility frontier, how can we improve enterprises鈥 productivity through precise estimation of technical efficiency? After combing through related literature, Prof. Yao Feng discovered that the efficiencies among the US manufacturing enterprises vary diversely, even more so in India and China. During his speech, Prof. Yao Feng shed systematic light on the major dimensions of efficiency measurement: Data Envelopment Analysis (DEA) and Stochastic Frontier Analysis (SFA). Prof. Yao Feng鈥檚 research has broadened the spectrum of the SFA method, brought in non-parametric coefficient estimation, and accentuated the influence of samples around a point estimate on the determination of such point estimate. During the Q & A session, teachers and students were engaged in the discussion of such topics as data stationarity, sample selection, and the application scope of mathematical models. Prof. Yao Feng explained, in plain language, the differences between classic methods and new models in the results of empirical analysis on specific issues.

      Following the speech, Prof. Li Fan gave her remarkable comments on Prof. Yao鈥檚 speech, encouraging students to apply non- and semi-parametric methods in an empirical manner. The salon was successfully concluded amidst thunderous applause.
