If you are interested in my research and teaching in the fields of applied economics (e.g. agriculture, development, energy), micro-econometric methods (e.g. productivity and efficiency analysis, limited dependent variables, impact assessment), and the "R" statistical software (e.g. my add-on packages), you could consider to 'follow' me on twitter.com: https://twitter.com/ArneHenningsen (where I post more news, e.g. new articles/papers, courses, job openings, than here).

Jeffrey Beall shut down his blog website about 'predatory' publishers [1]. This is a big loss for the scientific community, particularly for inexperienced researchers. It seems that he did not voluntarily shut down his website but that university politics and threats forced him to do this [2,3,4] :-( .

We have just published a new working paper: "New Insights into the Stochastic Ray Production Frontier". In my opinion, the Stochastic Ray Production Frontier (SRPF) is a greatly underused model specification for analysing multiple-input multiple-output production technologies that has some significant advantages over traditional specifications of output distance functions (e.g. Translog). In our new working paper, we point out and discuss some shortcomings of the SRPF and give practical advice on how to address these issues. We hope that our working paper will encourage more researchers and analysts to use the SRPF in their empirical analyses -- perhaps additionally to traditional specifications in order to conduct 'model averaging'. Using a Monte Carlo study, our earlier research has shown that taking the average values of the efficiency estimates of the SRPF and the efficiency estimates of traditional specifications gives more precise estimates than only using efficiency estimates of traditional specifications -- even if the data were generated based on the traditional specification (Henningsen, Henningsen, and Jensen, 2015).
