This article describes the influence of input quality and scarcity, environmental conditions, human capital, water price, and other variables on adoption rates for modern irrigation technologies in terms of both speed and extent of application. An empirical model is developed to apply these...

Adoption and abandonment processes are analyzed for seven irrigation technologies. A procedure is developed to estimate the technology cycle and applied to data available for citrus groves in several regions of Israel, and Gaza. The technology cycle was used to estimate diffusion-abandonment...

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...

Information on efficient regional patterns of agricultural production can be useful in devising policies for adjustments in farming that are consistent with modern conditions and concepts of economic development. Such knowledge can also indicate the amount and location of land to be withdrawn...

In many analyses of profit maximization, attention is directed to large herds and specialization in milk production. Why then do some farmers persist in keeping small dairy herds even when prices for Grade B milk become quite low? This article shows that even with relatively low prices for milk...
