A model for determination of the efficient combination of water quantity and quality (salinity) in irrigation is presented. The efficient combination is evaluated with respect to a predetermined threshold salt concentration in the soil solution. A leaching model, designed for tracing salt...

Intuitively, we would expect that an increase in the military preparations of potential enemies imply that the rival perceives an increase in the likelihood of future conflict. In this paper, we present a simple model that suggests that, surprisingly, the relationship is ambiguous. We find that...

In the defense policy literature, it is widely believed that there is a pronounced bias towards the procurement of a less than optimal number of excessively sophisticated weapons. In this paper, we consider the possibility that this perceived bias is the result of the timing and informational...
