W.D. Hamilton's Inclusive Fitness Theory explains the conditions that favor the emergence and maintenance of social cooperation. Today we know that these include direct and indirect benefits an agent obtains by its actions, and through interactions with kin and with genetically unrelated individuals. That is, in addition to kin-selection, assortation or homophily, and social synergies drive the...

All social insects are characterized by a reproductive division of labor. Within a colony only a few individuals reproduce (queens and in termites, also a king) while the large majority (workers and soldiers) forgo reproduction, at least temporarily. The evolution of such reproductive altruism can ultimately be explained by inclusive fitness theory. Here, I will review the proximate genetic mec...

Queues formed by social wasps to inherit the dominant position in the nest are analyzed by using a transient quasi-birth-and-death (QBD) process. We show that the extended nest life time due to division of labor between queen and helpers has a big impact for the nest productivity.

We introduce Division of Labor (DoL) from social insects to improve local optimisation of the Particle Swarm Optimiser (PSO). We compared the performance with the basic PSO, a GA and simulated annealing and found improvements around local optima. The PSO with DoL outperforms the basic PSO on most testcases and is comparable in local op-

This paper examined gendered housework in the larger context of comparative social change, asking specifically whether cross-national differences in domestic labor patterns converge over time. Our analysis of data from 13 countries (N =11,065) from the 1994 and 2002 International Social Survey Program (ISSP), confirmed that social context matters in shaping couples' division of labor at home, b...

Building on three widely accepted premises (productivity gains from the division of labor, efficiency gains derived from the proximity of suppliers and users of certain inputs, the division of labor is limited by the extent of the market) this paper shows that a small, open economy may be caught in an underdevelopment trap in which a shallow division of labor (i.e., a low variety of specialized...

We consider why the gender division of labor is so often enforced by custom and why customary gender divisions of labor generally involve both direction and prohibition. In our formal model, agents first learn skills and then enter the marriage market. We show that wasteful behavior may emerge due to strategic incentives in specialization choice and human capital acquisition and that both probl...
