International best-shot public goods and foreign aid

This note corrects an analytical mistake of Jayaraman and Kanbur (1999) in their analysis of a Stackelberg game of the voluntary contribution to an international best-shot public good by a donor and a recipient. It shows that, depending on players' preferences, the donor may choose not to contribute but make a positive direct income transfer to the recipient who will then contribute to the best-shot public good.best-shot public goods

The effect of the status quo tie-breaking rule on prize winning

This paper considers a contest in which two identical players participate to compete for an indivisible prize. It is shown that, in the presence of incomplete information, the player favored by the status quo tie-breaking rule may be less likely to get the prize than his competitor, even though, under the coin toss tie-breaking rule, the two players participate with the same positive probability and hence are equally likely to get the prize.

Threshold levels and the realization of a group benefit

This paper considers a voluntary contribution threshold game in which a group benefit is realized only if the number of contributors at least reaches a threshold level, and analyzes the effect of the threshold level on the likelihood that the group benefit is realized. Changes in the threshold level in interior symmetric equilibrium have two effects on the likelihood, the direct, threshold effect and the indirect, strategic effect. While the direct effect is always negative, the indirect effect can be either positive or negative. And the net effect is not necessarily negative.direct effect

Microwave Surveillance based on Ghost Imaging and Distributed Antennas

In this letter, we proposed a ghost imaging (GI) and distributed antennas based microwave surveillance scheme. By analyzing its imaging resolution and sampling requirement, the potential of employing microwave GI to achieve high-quality surveillance performance with low system complexity has been demonstrated. The theoretical analysis and effectiveness of the proposed microwave surveillance method are also validated via simulations.Comment: 4 pages, 11 figures, submitted for possible journal publicatio
