In the stochastic frontier model, we extend the multivariate probability statements of Horrace (J Econom, 126:335–354, <CitationRef CitationID="CR22">2005</CitationRef>) to calculate the conditional probability that a firm is any particular efficiency rank in the sample. From this, we construct the conditional expected efficiency rank...</citationref>

In the stochastic frontier model we extend the multivariate probability statements of Horrace (2005) to calculate the conditional probability that a firm is any particular efficiency rank in the sample. From this we construct the conditional expected efficiency rank for each firm. Compared to...

The truncated (below zero) normal distribution is considered. Some existing results are surveyed, and a recursive moment formula is used to derive the first four central moments in terms of the mean and variance of the underlying normal and in terms of lower moments of the truncated...

Consumers choose from among the varieties of two brands and an outside good using order statistics. We analytically derive demand functions conditional on their valuations of the varieties being distributed independently uniform. Based on this theory, we estimate a threeparameter empirical...

In parametric stochastic frontier models, the composed error is specified as the sum of a two-sided noise component and a one-sided inefficiency component, which is usually assumed half-normal, implying that the error distribution is skewed in one direction. In practice, however, estimation...

A new gender wage gap decomposition methodology is introduced, which does not suffer from identification problems caused by unobserved nondiscriminatory wage structure. The methodology is used to measure the relative size of Korean gender wage gaps, from 1994 to 2000 across industries,...

We use order statistics to analytically derive demand functions when consumers choose from among the varieties of two brands—such as Coke and Pepsi—and an outside good. Soft-drinks have no price variability across varieties within a brand, so traditional demand systems (e.g., mixed logit)...
