| System of input demand functions is estimated to examine the impact of farm program payments on farm economic structure. Influence of farm program payments on input resource use for the time periods corresponding to the thirteen farm bills in effect since 1938 is also examined. Empirical application to Nebraska agriculture sector for the period 1936-2004 indicate positive impact of farm program payments on farm real estate, breeding livestock and other inputs. Negative influence of farm program payment on the use of farm equipment, farm labor, farm inputs, chemicals and energy was observed during the same period. |

| 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. |

| 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. |

| Simulation is used to examine impacts of land expansion strategies and self-imposed borrowing limits upon growth and survival odds of a dryland wheat farm over a 15-year period. Compared to share-rent expansion, purchasing land shows only marginally great growth at best, with substantially higher odds of firm failure. A tradeoff of enhanced survival at the expense of reduced growth results from more conservative borrowing for land. The marginal value of liquidity (for assisting survival) is relatively high at lower levels of credit reserves. |

| A recent survey indicated that many procedures view risk in a safety-first context. Traditional methods used to impose safety-first constraints in optimization models have often been difficult to implement. This is particularly true when endogenous decisions affect the distribution of the chance-constrained random variable. This paper presents a method whereby probabilistic constraints can be easily imposed upon finitely discrete random variables. The procedure uses a linear version of the lower partial moment stochastic inequality. The resulting solutions are somewhat conservative but are less so than the results using the previously published mean income-absolute deviation stochastic inequality. |

| This article addresses (1) the differences in machinery cost estimating techniques, particularly for depreciation and opportunity cost, and (2) the necessary modifications in cost estimating techniques to account for the changing monetary base under inflation. The conditions under which capital budgeting and traditional budgeting differ are examined on a before tax and after tax basis, with and without inflation. The variations in cost estimates depending upon techniques, and with and without inflation, are compared. |
