Ramped calibration strips have been suggested as a way for grain producers to determine nitrogen needs more accurately …. The strips use incrementally increasing levels of nitrogen and enable producers to conduct an experiment in each field to … determine nitrogen needs. This study determines whether predictions from the program Ramp Analyzer 1.2 are replicable in …

This paper investigates sensitivity of U.S. natural gas price to crude oil price changes, using time …-varying coefficient models. Identification of the range of variation of the sensitivity of natural gas price to oil price change allows …

The aim of this study is to provide a methodology for the joint estimation of efficiency and market power of individual … differences in the market power and efficiency levels of banks between the two samples. Market power estimates indicate fairly … some banks deviates from the average behavior, and this finding has important policy implications. Finally, efficiency and …

efficiency is in place. Here we address the question of technical efficiency with respect to university’s size. The crucial … concept in this analysis is conditional efficiency and the ratio of size-conditional to unconditional efficiency measures. In … particular we take use of robust order-m efficiency scores presented in Cazals, Florens and Simar (2002) and generalized in …
