The “law of scarcity” is that scarceness is rewarded; recall, for example, the diamonds and water paradox. In this paper, furthering research initiated in Kelso and Crawford (1982, Econometrica 50, 1483-1504) for matching models, we demonstrate a law of scarcity for cores and approximate cores of games. ∗This research was partly undertaken when this author was in the IDEA Ph.D Program of the Au...
In order to investigate the major sources and cycling of mercury in the Negro River Basin (Amazon), total metal measurements were carried out in soils, in river and lake waters, in the atmosphere, and in bulk precipitation during the period 1995 throughout 1998. Median values of 1.3 ng m(-3) in the atmosphere, 172 microg kg(-1) in soils, 4.6-7.5 ng l(-1) in three different lakes, 4.5 ng l(-1) i...
Measuring poverty trends and dynamics is an important undertaking for reduction policies, which further highlighted by the SDG goal 1 on eradicating 2030. We provide a broad overview of pros cons imputation in data-scarce environments, update recent review papers, point to latest research topics. briefly two common uses methods that aim at tracking over time estimating dynamics. also discuss ne...
Does water scarcity induce conflict? And who would engage in a water scarcity conflict? In this paper we look for evidence of the relation between water scarcity and conflictive behavior. With a framed field experiment conducted with smallholder irrigators from semi-arid Tanzania that replicates appropriation from an occasionally scarce common water flow we assess what type of water users is mo...

Assuming the abc-conjecture we show that there are only nitely many powerful binomial coeecients ? n k with 3 k n=2; in fact, that if q 2 divides ? n k that q n 2 ? n k o(1). Unconditionally we show that there are N 1=2+o(1) powerful binomial coeecients in the top N rows of Pascal's Triangle.
Resource scarcity poses challenging demands on the cognitive system. Budgeting with limited resources induces an attentional focus on the problem at hand, but it also comes with a cost. Specifically, scarcity causes a failure to notice beneficial information in the environment, or remember to execute actions in the future, that help alleviate the condition of scarcity. This neglect may arise as...
