Several spatial econometric approaches are available to model spatially correlated disturbances in count models, but there are at present no structurally consistent count models incorporating spatial lag autocorrelation.

This article provides a farm sector comparison of levels of capital input for fourteen OECD countries for the period 1973 to 2002. The starting point for construction of a measure of capital input is the measurement of capital stock. Estimates of depreciable capital are derived by representing...

A stochastic optimization model was developed to determine optimal testing strategies, costs, and risks for dual marketing of genetically modified (GM) and non-GM wheat in an export supply chain. The optimal testing strategy is derived that minimizes disutility of additional system costs due to...
