Characterization of optima in smooth Pareto economic systems
(Elsevier, 1975)
Simple techniques of calculus and geometry are used to study and characterize the optima of pure exchange economies in which the utility functions are smooth but not necessarily convex. It is also shown how one can reduce ...
Addendum to: A bound for the fixed-point index of an area-preserving map with applications to mechanics
(Springer-Verlag, 1976-02)
Modeling and analyzing HIV transmission: the effect of contact patterns
(Elsevier, 1988-12)
A compartmental model is presented for the spread of HIV in a homosexual population divided into subgroups by degree of sexual activity. The model includes constant recruitment rates for the susceptibles in the subgroups. ...
Counting Groves-Ledyard equilibria via degree theory
(Elsevier, 1983-10)
We study the Groves-Ledyard mechanism for determining optimal amounts of public goods in economies whose agents have the most general class of preferences for which a Pareto amount of public goods can be computed independently ...
ALTRUISM VIA KIN-SELECTION STRATEGIES THAT RELY ON ARBITRARY TAGS WITH WHICH THEY COEVOLVE
(Blackwell Publishing Ltd, 2004-08)
Hamilton's rule explains when natural selection will favor altruism between conspecifics, given their degree of relatedness. In practice, indicators of relatedness (such as scent) coevolve with strategies based on these ...
The spread and persistence of infectious diseases in structured populations
(Elsevier, 1988)
A basic assumption of many epidemic models is that populations are composed of a homogeneous group of randomly mixing individuals. This is not a realistic assumption. Most actual populations are divided into a number of ...
A bound for the fixed-point index of an area-preserving map with applications to mechanics
(Springer-Verlag, 1974-09)
The stochastic SI model with recruitment and deaths I. comparison with the closed SIS model
(Elsevier, 1993)
We compare the stochastic and deterministic version of an SI model with recuitment, background deaths, and deaths due to the disease. For the stochastic version, analysis of the mean number of susceptibles, m, and infecteds, ...
Averting expenditure and the cost of pollution
(Elsevier, 1981-12)
The paper considers the relationship between the willingness to pay for environmental quality and averting expenditures--that is, the costs of measures undertaken in efforts to counteract the consequences of pollution. The ...
Job dissatisfaction as a possible risk factor in coronary heart disease
(Elsevier, 1971-05)
