TL;DR: In this paper, a stochastic frontier production function is defined for panel data on firms, in which the nonnegative technical inefficiency effects are assumed to be a function of firm-specific variables and time.
Abstract: A stochastic frontier production function is defined for panel data on firms, in which the non-negative technical inefficiency effects are assumed to be a function of firm-specific variables and time. The inefficiency effects are assumed to be independently distributed as truncations of normal distributions with constant variance, but with means which are a linear function of observable variables. This panel data model is an extension of recently proposed models for inefficiency effects in stochastic frontiers for cross-sectional data. An empirical application of the model is obtained using up to ten years of data on paddy farmers from an Indian village. The null hypotheses, that the inefficiency effects are not stochastic or do not depend on the farmer-specific variables and time of observation, are rejected for these data.

TL;DR: In this paper, the expected value of u, conditional on (v − u ) is considered, where v is a normal error term representing pure randomness, and u is a non-negative error term describing technical inefficiency.

TL;DR: In this article, a rational political explanation for the notorious inefficiency of pork-barrel projects with an optimization model of legislative behavior and legislative institutions is presented. But the model emphasizes the importance of the geographic incidence of benefits and costs owing to the geographic basis for political representation.
Abstract: This essay offers a rational political explanation for the notorious inefficiency of pork barrel projects with an optimization model of legislative behavior and legislative institutions. The model emphasizes the (economically arbitrary, from a welfare point of view) importance of the geographic incidence of benefits and costs owing to the geographic basis for political representation. We explore the implications of a legislator's objective function and derive conditions under which a representative legislature will select an omnibus of projects each of which exceeds the efficient scale.

TL;DR: A sheet which is a blend of water-insoluble fibers and pieces of film of a dry material which converts to a gel quickly on contact with a large amount of water.
Abstract: Most implementations of genetic algorithms experience sampling bias and are unnecessarily inefficient. This paper reviews various sampling algorithms proposed in the literature and offers two new algorithms of reduced bias and increased efficiency. An empirical analysis of bias is then presented.
