In this paper we derive both primal and dual-cost systems in which the stochastic specifications arise from the model (random environment or measurement errors and optimization errors)—not tacked on at the end after the deterministic system is worked out. Derivation of the error structures is...

This paper considers a generalized panel data model of polychotomous and/or sequential switching which can also accommodate the dependence between unobserved effects and covariates in the model. We showcase our model using an empirical illustration in which we estimate scope economies for the...

We introduce a novel approach to modeling the impact of institutional quality on firm performance. Our methodology enables us to estimate the marginal effect of institutional quality on TFP, factor inputs and output of each firm, which gives us within-country distributions of these effects and...

In the neoclassical production theory technical change (TC) is specified as a function of time. However, some exogenous external factors other than time can also affect the rate of TC. In this paper, we model TC via a combination of time trend (purely non-economic) and other observable exogenous...

Credit risk is crucial to understanding banks’ production technology and should be explicitly accounted for when modeling the latter. The banking literature has largely accounted for risk by using ex-post realizations of banks’ uncertain outputs and the variables intended to capture risk....

This paper presents new nonparametric measures of scale economies and TFP growth for U.S. banks. Unlike previous studies that use fully nonparametric models, our approach controls for time-invariant unobserved heterogeneity among banks in estimating returns to scale, TFP growth and its...

This paper raises concerns about the econometric approach used in the literature to estimate credit unions’ production technologies. We show that the existing studies did not recognize heterogeneity amongst credit unions’ technologies as captured by (endogenously selected) differing output...

This paper presents new evidence regarding the relation between profit, revenue, and cost efficiencies of U.S. commercial banks. Building on the widely used nonstandard profit function (NSPF) approach, we show (i) why estimation of NSPF would be wrong and (ii) how revenue and cost efficiencies...
