A Bioeconomic Approach To Marriage And The Sexual Division Of Labor, Michael Gurven, Jeffrey Winking, Hillard Kaplan, Christopher Von Rueden, Lisa Mcallister

ESI Publications

Children may be viewed as public goods whereby both parents receive equal genetic benefits yet one parent often invests more heavily than the other.We introduce a microeconomic framework for understanding household investment decisions to address questions concerning conflicts of interest over types and amount of work effort among married men and women. Although gains and costs of marriage may not be spread equally among marriage partners, marriage is still a favorable, efficient outcome under a wide range of conditions. This bioeconomic framework subsumes both cooperative and conflictive views on the sexual division of labor. We test hypotheses concerning marriage markets, …

The Multiple Dimensions Of Male Social Status In An Amazonian Society, Christopher Von Rueden, Michael Gurven, Hillard Kaplan

ESI Publications

"In all human societies, individuals differ in social status depending upon their age and personal ability (Sahlins, 1958; Service, 1971). In laboratory-based small group studies, status hierarchies emerge spontaneously (Bass, 1954; Campbell et al., 2002; Kalma, 1991). Even among “egalitarian” foragers, who are characterized by widespread resource sharing (Kaplan & Gurven, 2005; Winterhalder, 1986) and some degree of status-leveling (Cashdan, 1980), certain individuals consume more resources, get the best pick of mates, and take a more central role in group decision-making (Boehm, 1999; Trigger, 1985; Wiessner, 1996). Whether implicit or overt, classification by social status is a human universal. While …

Aging And Inflammation In Two Epidemiological Worlds, Michael Gurven, Hillard Kaplan, Jeffrey Winking, Caleb Finch, Eileen M. Crimmins

ESI Publications

Humans evolved in a world with high levels of infection resulting in high mortality across the life span and few survivors to advanced ages. Under such conditions, a strong acute-phase inflammatory response was required for survival; however, inflammatory responses can also promote chronic diseases of aging. We hypothesize that global historical increases in life span at older ages are partly explained by reduced lifetime exposure to infection and subsequent inflammation. To begin a test of this hypothesis, we compare C-reactive protein (CRP); levels in two populations with different epidemiological environments: the Tsimane of Bolivia and persons in the United States. …

The Role Of Economics In Achieving Welfare Gains For Animals, Jennifer Fearing, Gaverick Matheny

State of the Animals 2007

The demand for animal products and services is a powerful economic force in society, and multibillion-dollar industries are organized around this demand. These industries often face increased costs by improving animal welfare and are quick to use economic arguments against proposed welfare reforms (see sidebar on page 169). These arguments, while often specious, can influence consumers, voters, and policy makers. Citizens are less likely to support animal welfare reforms they’ve been told will double their shopping bill or impoverish family farmers.

Animal welfare advocates cannot respond to these economic arguments with moral rhetoric alone. Instead, non-governmental observers (NGOs) must challenge …

The Evolution Of Human Life Expectancy And Intelligence In Hunter-Gatherer Economies, Hillard Kaplan

ESI Publications

The economics of hunting and gathering must have driven the biological evolution of human characteristics, since hunter-gatherer societies prevailed for the two million years of human history. These societies feature huge intergenerational resource flows, suggesting that these resource flows should replace fertility as the key demographic consideration. It is then theoretically expected that life expectancy and brain size would increase simultaneously, as apparently occurred during our evolutionary history. The brain here is considered as a direct form of bodily investment, but also crucially as facilitating further indirect investment by means of learning-by-doing.

The State Of The Economy And Animal Welfare, Michael W. Fox

Animal Welfare Collection

An economic depression inevitably means that the under-privileged are compelled to suffer, but the plight of animals during "hard times" is often overlooked. Further, the present administration's budget cuts, and the pro-industry policies expressed by the Environmental Protection Agency and the Department of the Interior, in conjunction with the attempted financial emasculation of the U.S. Department of Agriculture's Animal and Plant Health Inspection Service (responsible for enforcing the Animal Welfare Act), all add insult to injury. Clearly, in such difficult economic times, the needs of people will inevitably take precedence over those of animals. But a society that unconditionally places …
