Numerous studies agree that income inequality, rather than absolute income, is an important predictor of happiness. However, its specific role has been controversial. We argue that income inequality and happiness should exhibit an inverted U-shaped relationship due to the dynamic competing process between two effects: when income inequality is relatively low, the signal effect will be the domin...

A simple generative model of a foraging society generates significant wealth inequalities from identical agents on an equal opportunity landscape. These arise in both equilibrium and non-equilibrium regimes with some societies essentially never reaching equilibrium. Reproduction costs mitigate inequality beyond their affect intrinsic growth rate. The highest levels are found during regimes. Ine...

In the paper, we study dynamic h-convexity for interval valued functions. Some generalizations of Jensen’s inequality in analysis h-convex functions on time scales are proved paper. seek applications generalized inequality, Hermite-Hadamard type inequalities established. Further discrete analogues newly results also presented numerical examples provided to check validity results.

We consider linear plants controlled by dynamic output feedback which are subjected to blockdiagonal stochastic parameter perturbations. The stability radii of these systems are characterized and it is shown that, for real data, the real and the complex stability radii coincide. A corresponding result does not hold in the deterministic case, even for perturbations of single output feedback type...

Households became more geographically segregated by income in the United States between 1970 and 1990. Research shows that growing up in a poor neighborhood is associated with worse outcomes for children. This suggests that economic segregation may be harmful to children. Economic inequality also increased between 1970 and 1980. Theoretical arguments suggest that the increase in inequality led ...

In laboratory public goods experiments, subjects make decisions about how much of a fixed endowment to contribute to the production of a public good in a sequence of periods. The nature of subjects’ responses to information about others’ decisions can help distinguish between alternative motives for giving, such as altruism, warm glow, reciprocity and inequality aversion. In this paper we reana...

This paper presents an application of Harmony Search algorithm (HSA) to solve the Dynamic Economic-Environmental Dispatch (DEED) problem under some equality and inequality constraints. The equality constraints reflect a real power balance, and the inequality constraint reflects the limits of real generation. The voltage levels and security are assumed to be constant. Dynamic Economic-Environmen...
