How Large Should Whales Be?

The evolution and distribution of species body sizes for terrestrial mammals is well-explained by a macroevolutionary tradeoff between short-term selective advantages and long-term extinction risks from increased species body size, unfolding above the 2 g minimum size induced by thermoregulation in air. Here, we consider whether this same tradeoff, formalized as a constrained convection-reactio...

The Strategic Petroleum Reserve : how large should it be

This paper is the final report on a study carried out for the U.S. Department of Energy, concerning the optimal size of the Strategic Petroleum Reserve (SPR). The purpose of the SPR is to diminish U.S. vulnerability to, as well as to offer protection against, possible future oil embargoes. In this study we formulate the problem of determining the optimal size of the SPR as a parametric bimatrix...

How Large a Coalitional Should Be to Manipulate an Election?

Assuming the IC conjecture, we show that, for any faithful scoring rule, when the number of participating agents n tends to infinity, the probability that a random profile will be manipulable for a coalition of size Cnα, with 0 ≤ α < 1/2 and C constant, is of order O ( 1/n1/2−α ) .
