Measuring Price and Yield Risk
Y variability for a given crop differs geographically and depends on soil type and quality, climate, and the use of irrigation.

Using this measure, variability in corn yields, for example, ranges from about 0.2 to abo...

In the realm of information security, lack of information about other users’ incentives in a network can lead to inefficient security choices and reductions in individuals’ payoffs. We propose, contrast and compare three metrics for measuring the price of uncertainty due to the departure from the payoffoptimal security outcomes under complete information. Per the analogy with other efficiency m...
