Efficient operation of agricultural credit markets is very important both for the producer as well as for the policy makers. DEA approach is used to calculate productivity analysis which allows decomposition of sources of productivity changes into efficiency and technical change. Measured...

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...

This paper addresses the issue of the shadow price of environmental bads treated as an undesirable output (normal input) with weak (strong) disposability in a two-stage estimation. Nebraska agriculture sector time series data used is spread over 1936-94. Results indicate the difference in the...

The existence of Weak Separability aggregates of inputs and outputs is tested using a Translog production and input requirement function for the Nebraska Agricultural sector for 1936-1994. A separability test was performed only after testing time series properties by comparing the null...

Yield variability can be significantly higher at the farm level than at more aggregated levels, including the county. However, due to a dearth of available farm level data, much stochastic analysis involving farm yields utilizes more aggregated yield data as a proxy for the farm level. We...

We demonstrate that Theil-type variance corrections are required to obtain consistent marginal effect estimates in Nelson-Olsen's two-stage limited dependent variable (2SLDV) model. As Theil's residuals-based corrections are infeasible with 2SLDV, we present variance correction procedures shown...

This paper studies the welfare impact of alternative scenarios of trade protectionism and liberalization in Argentina. The impact of the different trade policies is assessed in two different ways. We first use the multi-sectoral and multi-regional computable general equilibrium MIRAGE model to...

We conduct models and tests to ascertain whether there are speculative bubbles and which factors contribute to the bubbles if there exits one. In the model, we use the option value to represent the investment value of farm real estate and compare the option value, calculated from dynamic...
