| Stochastic frontier analysis, which is used to estimate the technical efficiency, is extended to examine the market structure, conduct and performance hypothesis for the U.S. trucking industry. The technical efficiency measure takes into account not only the relationship between inputs used in the production of output but also simultaneously examine the importance of market structure conduct factors on the performance of the firm. An empirical application to U.S. trucking carriers over the period 1994-2003 is examined. Results reveal that the variables average haul, average load, debt-to-equity and market concentration significantly affected technical efficiency. Capital, fixed and variable input variables were significant in the production function... |

| This study addresses the impact of trade openness on technical efficiency in the U.S. agricultural sector. The results indicate that trade protectionism illustrated with a decrease in the share of agricultural imports in agricultural GDP led to an increase in technical efficiency. A change in the share of agricultural exports in agricultural GDP had no impact on technical efficiency. These results are partially consistent with the premise of the new trade theory, but also seem to be driven by the intricacies of the agricultural sector and agricultural policy in the United States and internationally. |

| Using a nonparametric linear programming approach, our contribution is to examine if efficiency gains in Western crop production are realized due to diversification and to demonstrate that the diversification efficiency gains realized are a product of economies of scope efficiency gains and scale efficiency gains. The analysis employed cropping sector data for six major crops for the period, 1975-1996. Results indicate efficiency gains are realized due to diversification for all the two-crop combinations. |

| This study examines how federal farm policies, specifically crop insurance, have affected the farm economic structure of North Dakota’s agriculture sector. The system of derived input demand equations is estimated to quantify the changes in North Dakota farmers’ input use when they purchase crop insurance. Further, the cumulative rolling regression technique is applied to capture the varying effects of the farm policies over time. Empirical results from the system of input demand functions indicate that there is no moral hazard since North Dakota farmers will increase fertilizer and pesticide use in the presence of crop insurance. Results also indicate that farmers in this state will not increase the use of land. |

| Geographical information systems and econometric tools were used to determine the socioeconomic impacts of bypasses in Atlanta-Birmingham Metropolitan area. Mean household income and per capita income of county is separately used as a proxy for anticipated bypass impact as a function, of socioeconomic variables: farm income, farm employment, non-farm employment, age groups, and population density. The cross-sectional and the time series data were pooled together and estimated as panel data. Results indicate that most of these variables have positive impacts on growth. |

| The implications of treating environmental pollution as an undesirable output (weak disposability) as well as a normal input (strong disposability) on the direct and indirect shadow price and cost estimates of nitrogen pollution abatement is analyzed using Nebraska agriculture sector data. The shadow price of nitrogen pollution abatement treated as an undesirable output represents the reduced revenue from reducing nitrogen pollution. In contrast, the shadow price of nitrogen pollution abatement treated as an input reflects the increased cost of reducing nitrogen pollution. For the 1936-97 period, the estimated shadow price and cost of nitrogen pollution abatement for Nebraska ranges from $0.91 to $2.21 per pound and from $300 to $729 million respectively. |

| This paper has a three fold contribution to the existing literature - 1) Indian state level sorghum input and output data for the period 1970-71 to 2000-01 is collected, 2) non-parametric linear programming productivity measures are estimated, and 3) examine the impact of policy variables like percent of high yielding varieties, percent under irrigation, and herfindahl index of seasonal production (rabi and kharif) on productivity using two way random effects panel model |
