A practical mathematical programming model for the strategic fuel diversification problem is presented. The model is designed to consider the tradeoffs between the expected costs of investments in capacity, operating and maintenance costs, average fuel costs, and the variability of fuel costs....

Mathematical programming analysis has been quite effective for commercial farm planning in developed countries, but less so for subsistence farms in developing countries. In particular, it is difficult to reproduce the level of diversification observed on subsistence farms using a simple profit...

Since the first half of the 20th century, the input-output (IO) table has been the backbone of much empirical work used to support policy analysis and develop economy-wide models. The need for accurate, up-to-date IO tables is thus essential for establishing the validity of the empirical work...

A model was developed and used to determine the optimal slaughter weights of pigs with heterogeneous growth raised in a 1,000 head barn and marketed in truckload groups. Explicitly recognizing the heterogeneity of pig weights and marketing the herd over time in truckload batches can...

The CES is generalized by extension of the work of Hanoch (1975) resulting in implicit, direct and indirect relationships between utility and consumption. Expressions for substitution and income elasticities are developed and observed to be variable, rather than constant as in the CES case.
