Incorporating monotonicity and concavity conditions in flexible functional forms

Dynamic changes and heterogeneity in technical efficiency of broiler production under African swine fever shocks: Evidence from production organization and farm size

“…This indicates that the unrestricted Translog production function used in this study does not fully satisfy the concavity requirement within the sample range. This finding is consistent with previous evidence that unrestricted Translog functions may violate regularity conditions in production theory ( Yang, 2020 ; Terrell, 1996 ; Henningsen and Henning, 2009 ). In other words, the flexibility of the Translog function improves its ability to capture complex input relationships, but it may also lead to local violations of monotonicity or concavity.…”

Constraints in models of production and cost via slack-based measures

“…These differences between our method and Terrell (1996) or O'Donnell and Coelli (2005) can be explained by their higher acf's which do not help convergence. As we see from Fig.…”
