| Traditional measures of agricultural productivity only incorporate those inputs and outputs that are recorded in market transactions. However, such measures do not account for externalities such as environmental damage. This study uses an output distance function framework to estimate a Malmqvist productivity index for a panel of Great Plains states then adjusts this index by incorporating nitrogen effluent into the analysis. We estimate that long-run environmentally-adjusted productivity growth was approximately 13 percent below the unadjusted rate during the sample period. However the environmentally sensitive productivity rate actually exceeded the unadjusted rate in recent years, reflecting reductions in the discharge of agricultural nitrogen into... |

| This paper adapts a partial equilibrium approach of Allais and Diewert to measure the efficiency loss in the producing sector due to quotas. The measure of waste is the additional profits available for reallocation subject to constraints that the welfare of persons and firms outside the sector is unaffected. It is relevant to a sector which faces fixed prices for some commodities, but endogenous prices for others. Tobacco quotas in the United State are estimated to have caused quota-induced producer-sector waste of approximately $95 million per year during 1950-82, or about 3 percent of the average value of the crop. |

| Agricultural productivity in 41 Sub-Saharan Africa (SSA) countries from 1960 to 1999 is examined by estimating a semi-nonparametric Fourier production frontier. Over the four decades the estimated rate of productivity change was 0.83% per year, although the average rate from 1985-99 was a strong 1.90% per year. Former UK colonies exhibited significantly higher productivity gains than others, while Liberia and countries that had been colonies of Portugal or Belgium exhibited net reductions in productivity. We measure a significant reduction in productivity during political conflicts and wars, and a significant increase in productivity among those countries with a measure of political rights and civil liberties. |

| Recent studies have revealed that less developed countries (LDCs) have been taxing their agricultural sectors at rates of 40-50%. This study uses quantity-based general equilibrium measures of deadweight loss to evaluate the cost of these distortions in 18 of these countries. The Allais-Debreu loss measures indicate that from 7-16% of either output or of the agricultural resource base has been wasted due to the associated misallocation of agricultural inputs across these countries. |

| This study estimates nonparametric non-stochastic Malmquist indices and a stochastic Fourier production frontier to examine agricultural productivity and its interactions with socio-political institutions in 41 sub-Saharan African countries during 1961-1999. We have learned from this study that on average, agricultural productivity in SSA was negative during the 1960's and 1970's, but has been positive during the last two decades. Institutions offer a significant explanation of at least some of the differential performance across countries. |

| This study analytically evaluates the impact of technological change on output and input markets in a competitive industry of identical firms. Firm-level technology and technological change are represented parametrically as local approximations to unknown functional forms. The comparative statics analysis solved for changes in equilibrium market prices and quantities as functions of parameters that characterized technological change. The technology-induced shift-weighted induced change input prices. The model provides a consistent and systematic framework for evaluating the impact of technological change, either ex ante or ex post. |
