Sex Differences in the Ultimatum Game: An Evolutionary Psychology Perspective

In the two-person ultimatum game, an allocator is required to split a given sum of money with a recipient. Subsequently the recipient can either accept or reject the offer. If it is accepted, both players receive their respective splits, while if it is rejected neither of them get anything. Using evolutionary psychology as the theoretical framework, we predicted and found that males made more generous offers when pitted against a female as opposed to a male. While females made equal offers independently of the sex of the recipient. That male allocators are altruistic towards female recipients and competitive with male recipients is construed as a manifestation of social rules, which evolve from the male pre-disposition to use resources for attracting mates. In contrast, females have not evolved such a pre-disposition, and thus, female allocators are more concerned about fairness when making offers to recipients. Several alternate explanations of the above findings are discussed and the evolutionary explanation is concluded as the most parsimonious one. Other potential moderators that are amenable to evolutionary explanations, namely, physical attractiveness, age and ethnicity of participants, are also discussed in this context.

Conference Announcement

This paper presents a case study of a landslide that devastated a small rural community in the redwoods of northern California. This seemingly mundane event is used to explore several insights offered by recent literature on environmental risk, and illustrate the extent to which our reliance on modern, technologically complex industrial systems as the basis for risk scholarship may limit our understanding of the role of environmental risk in society. This landslide, and the political upheaval that followed it, point to the need for more rigorous sociological analysis of how hazards , rather than risks, are legitimated in political discourse through a process called 'normalization'; and of the complex of organizational structures of causation that encourage the development of risky situations, not only in modern technological systems, but in systems of society-environment interaction with a much longer history, such as the extraction and management of timber.     

The Political Economy of Tax-Based Incomes Policy: Wealth Effects of Post Keynesian TIP

This paper explores the economics of electoral democracy, an almost entirely neglected subject. Running for office necessitates resources. But students of democracy have had almost nothing to say about how much money should be spent by candidates or where that money should come from. As a result, there is a gaping void in the theory of democracy. Joseph A. Schumpeter used a market analogy in his discussion of the electoral process, but even he did not discuss how electoral campaigns are to be paid for. In fact, the few citizens who largely fund campaigns for office in the United States purchase non-rivalrous influence. They obtain the ability to shape the policies that affect all citizens. In this way, political equality is undermined. The paper concludes that achieving a more representative political system can best be attained by treating political campaigns as a public good.     

An Economic Analysis of the Returns to Canadian Swine Research: 1974–97

This paper reports a new set of estimates of the returns to swine research in Canada. These estimates are obtained using Agriculture and Agri‐Food Canada's Canadian Regional Agricultural Model (CRAM). Positive Mathematical Programming is incorporated into the model for use in this study. The CRAM allows the effects of supply shifts from technological change in the hog industry to interact with product and factor market conditions in the rest of Canadian agriculture. Extensive sensitivity analysis is conducted to examine the robustness of the return estimates under variations in some of the key assumptions employed in the analysis. The costs of public and private sector swine research are estimated. Public sector research costs are inclusive of the marginal excess burden of taxation. Overall, the estimated benefits from Canadian swine research are high relative to the estimated costs for the time period considered. Previous estimates of the returns to Canadian swine research were obtained by Huot et al. (1989) with a partial equilibrium model that did not allow for intra‐sectoral resource use adjustments. The estimated returns obtained in the present study are generally higher than those obtained by Huot et al. For example, the estimates obtained from the direct application of the econometrically estimated supply function in this study gave an internal rate of return of about 124% and a benefit‐cost ratio of 22.4 to 1. Huot et al reported comparable estimates of about 43% for the internal rate of return and 6–7 to 1 for the benefit‐cost ratio. The differences in returns are not solely attributable to the use of a multi‐market versus a single‐market partial equilibrium approach. There are also differences in the estimates of the marginal excess burden of taxation between the two studies. L'analyse que void présente une nouvelle série d'estimations quant au rendement de la recherche porcine au Canada. Ces estimations dérivent du Modèle d'analyse régionale de l'agriculture du Canada (MARAC) du ministère canadien de l'Agriculture et de l'Agroalimentaire. Aux fins de la présente étude, on avait intégré au modèle une programmation mathématique positive. Le MARAC autorise l'interaction entre les retombées d'une modification de l'offre attribuable au virage technologique de l'industrie porcine et les conditions du marché des produits et des facteurs dans le reste de l'agriculture canadienne. Les auteurs ont effectué une analyse de sensibilité poussée en vue d'établir la robustesse de leurs estimations quand variaient quelques‐unes des principales hypotheses de l'analyse. On a estimé le coût de la recherche sur les pores poursuivie par les secteurs public et privé. Dans le secteur public, le coût de la recherche incluait une charge fiscale légérement excessive. Dans l'ensemble, la recherche sur les porcs entreprise au Canada a rapporté beaucoup comparativement à ce qu'elle a coûté pendant la période à l'étude. Les estimations antérieures, établies par Huot et ses collaborateurs (1989), venaient d'un modèle àéquilibre partiel ne permettant aucun ajustement pour l'utilisation intra‐sectorielle des ressources. Les revenus estimés ici sont généralement plus élevés que ceux de Huot et de ses collaborateurs. Ainsi, une application directe de l'offre estimée par des méthodes économétriques à l'analyse donne un taux de rendement interne d'environ 124 % et un indice de rentabilité de 22,4 pour 1. À titre de comparaison, Huot et ses collaborateurs rapportent des résultats d'environ 43 % pour le taux de rendement interne et de 6 à 7 pour 1 en ce qui concerne l'indice de rentabilité. Pareil écart ne résulte pas uniquement du choix d'un modèle àéquilibre partiel reposant sur plusieurs marchés au lieu d'un seul; on relève aussi des variations dans l'estimation du léger excès de la charge fiscale entre les deux études.     

A Behavioral Model of Unemployment,Sociotropic Concerns,and the Political Economy of Trade Policy

We present a behavioral model in which agents are concerned about the scarring effects from unemployment for themselves and others and explore the manner in which unemployment matters for trade policy. We derive three policy implications: the government has an incentive to increase employment in sectors characterized by “good jobs,” where the good job/bad job characterization depends on an industry's job creation and destruction rates; the government has an incentive to pursue this policy in a gradual fashion by channeling new and unemployed workers into the appropriate sector; and opposition to trade liberalization can be reduced by welfare state policies.     

Migration transition or migration transformation in the Asian dragon economies?

There has been a marked tendency to interpret the recent transformation of international migration systems in Eastern Asia in terms of a ‘migration transition’ model. The transition in these countries from net emigration to net immigration, with major inflows from poorer adjacent countries, is seen as being driven by an intricate regional pattern of uneven development but growing economic integration. This paper challenges this view through an examination of the trade, investment and migration linkages of the region’s four dragon economies (Hong Kong, Singapore, South Korea and Taiwan). It argues that the key influences on their international migration streams reflect, above all, the functions of these states as second-order, global city regions. Their place in the global capitalist system creates a shared demand for very particular types of both highly skilled and unskilled labour, but the migration policies of the four states are independently, and therefore distinctively, socially constructed. — Il y a une tendance à utiliser un modèle de ‘transition de migration’ pour interpréter les transformations récentes des systèmes de migration internationaux en Asie de l’est. La transition de l’émigration nette à l’immigration nette dans ces pays, avec des arrivées massives des pays adjacents plus pauvres, est supposée être due à un modèle régional complexe de développement inégal mais d’intégration économique croissante. Cet article questionne ce modèle et examine les liens entre le commerce, l’investissement, et la migration dans les quatre économies dragons de la région (Hong Kong, Singapour, la Corée du sud et Taï?wan). Il soutient que les influences majeures sur leur flux de migration internationale reflète avant tout les fonctions de ces états en tant que régions urbaines globales de deuxième ordre. Leur place dans le système capitaliste global crée une demande pour un type très particulier de travailleurs qualifiés et non qualifiés, mais les politiques de migration des quatre états sont indépendemment, et donc distinctement, socialement construites.     

Living conditions of mine workers from eight mines in South Africa

Poor living conditions are a consequence of the history of the South African mining industry (SAMI), despite legislation having been implemented to attempt to address this challenge. This paper describes the living conditions of mine workers from eight mines in South Africa in 2014, and assesses changes made over the previous decade. Qualitative and quantitative data were collected at three platinum, two gold, one coal, one diamond, and one manganese mine in 53 interviews with mine management, 11 interviews with labour representatives, 14 focus groups with mine workers, and 875 questionnaires completed by mine workers. The use of single-sex hostels and hostel room occupancy rates has reduced, while the use of living-out allowances (LOAs) has increased. Problems included the high proportions of informal accommodation; a lack of access to water, sanitation, and electricity; and poor roads. While improvements to the living conditions in the SAMI are evident, challenges still remain.
