This paper studies two models of rational behavior under uncertainty whose predictions are invariant under ordinal transformations of utility. The quantile utility model assumes that the agent maximizes some quantile of the distribution of utility. The utility mass model assumes maximization of the probability of obtaining an outcome whose utility is higher than some fixed critical value. Both models satisfy weak stochastic dominance. Lexicographic refinements satisfy strong dominance.The study of these utility models suggests a significant generalization of traditional ideas of riskiness and risk preference. We define one action to be riskier than another if the utility distribution of the latter crosses that of the former from below. The single crossing property is equivalent to a minmax spread of a random variable. With relative risk defined by the single crossing criterion, the risk preference of a quantile utility maximizer increases with the utility distribution quantile that he maximizes. The risk preference of a utility mass maximizer increases with his critical utility value.  相似文献

This paper examines the effects of introducing a variable dependency ratio in Dasgupta's (1969) model. We consider a case in which the probability of dying as well as the rate of participation in the labor force change with age. It is shown that the inclusion of those realistic demographic features slows down the optimal rate of population growth and increases the rate of consumption. In spite of the reduction in the rate of population growth, this rate can still be positive. The sensitivity of the solutions to changes in the demographic parameters of the model is examined.  相似文献

Manpower export and economic development: evidence from the Philippines   总被引:1,自引:0,他引:1  
The Philippines has actively pursued a policy of labor export with the expectation that it would relieve unemployment, augment the supply of skills, and relieve pressure on the balance of payments. It was also anticipated that the inflow of overseas workers' remittances would translate into increased investment, the sine qua non for economic development. However, recent evidence casts some doubt on the extent to which these goals have been achieved. Particularly in the areas of skill formation, there appears to be a significant discrepancy between anticipated and actual outcomes. Indeed, it appears that the labor export may reduce the supply of skills available since 1) many skilled and educated workers are taking jobs requiring skill levels lower than they possess, and 2) a large majority of returning workers do not want to take up employment in those occupations reliant on the skills they used abroad. There is conflicting evidence regarding the impact of labor export on Philippine industries. There is some anecdotal evidence that a few industries have suffered because of a loss of key workers. In general, however, it appears that unemployment is still quite significant in those occupations most heavily represented in labor export. Despite this observation, it may still be true that labor emigration is selective of only the best workers, implying a decline in quality of the work force and possibly productivity in certain industries. The export of professional, technical, and managerial workers is another issue. Unless it can be shown that these workers are in excess supply, it is not advisable to expand the number going abroad. Although their salaries may be higher, and hence their remittances greater, their loss can impose costs on indigenous industries well in excess of a any marginal gains. Remittances from overseas workers do constitute a relatively significant source of foreign exchange. However, the translation of remittances into investment has been restrained by the very low propensity of remittance recipients and returnees to undertake productive investment and by the diversion of remittances from formal banking channels into informal channels. Remittances which are being channeled through the formal banking sector constitute a potentially important source of loan funds, as well as providing a potential stimulus to indigenous industry.  相似文献

International labor standards take the form of Conventions and Recommendations that embody the agreements reached by a 2/3 majority of the representatives of Governments, Employers, and Workers of International Labour Office (ILO) member states. Originally designed to guard against the danger that 1 country or other would keep down wages and working conditions to gain competitive advantage and thereby undermine advances elsewhere, international labor standards have also been inspired by humanitarian concerns--the visible plight of workers and the physical dangers of industrialization and by the notion of social justice, which embraces wellbeing and dignity, security, and equality as well as a measure of participation in economic and social matters. ILO standards apply to workers generally and therefore also to migrant workers, irrespective of the fact that the general standards are complemented by standards especially for migrant workers. The social security protection of migrant workers has been dealt with in ILO instruments primarily from the angle of equality of treatment but also from that of the maintenance of acquired rights and rights in course of acquisition, including the payment of benefits to entitled persons resident abroad. The ILO Conventions on migrant workers and the Recommendations which supplement them deal with practically all aspects of the work and life of non-nationals such as recruitment matters, information to be made available, contract conditions, medical examination and attention, customs, exemption for personal effects, assistance in settling into their new environment, vocational training, promotion at work, job security and alternative employment, liberty of movement, participation in the cultural life of the state as well as maintenance of their own culture, transfer of earnings and savings, family reunification and visits, appeal against unjustified termination of employment or expulsion, and return assistance. ILO's supervisory mechanism consists basically of a dialogue between the ILO and the Government that is responsible for a law, regulation, or practice alleged to be in contravention of principles it voluntarily accepted. The control machinery is often set in motion by workers' organizations. The UN General Assembly is currently elaborating a new instrument designed to cover both regular and irregular migrant workers and their families.  相似文献

This paper extends the author's recent work on dynamically consistent consequentialist social norms for an unrestricted domain of decision trees with risk to trees in which the population is a variable consequence — i.e., endogenous. Given a form of ethical liberalism and ethical irrelevance of distant ancestors, classical utilitarianism is implied (provided also that a weak continuity condition is met). The repugnant conclusion that having many poor people may be desirable can be avoided by denying that individuals' interests extend to the circumstances of their birth. But it is better avoided by recognizing that potential parents have legitimate interests concerning the sizes of their families.That action is best, which procures the greatest happiness for the greatest numbers. Francis Hutchison (1725).An abiding interest in concepts of optimality for the choice of population has been stimulated by frequent discussions with Partha Dasgupta. This paper was presented at the seminar on Distributive Justice and Inequality at the Wissenschaftskolleg zu Berlin, May 1986. I am grateful to the audience for their helpful comments, especially Maurice Salles and Patrick Suppes, and especially to John Weymark for carefully reading and suggesting distinct improvements to the earlier version.  相似文献

Excuse-making is defined, and the issues of deception and verbal/nonverbal presentations are discussed in regard to the excuse process. Subsequently, the deception and verbal/nonverbal issues are described in greater detail in the context of whether the excuse occurs temporally after a negative outcome (retrospective), before a negative outcome (anticipatory), or as part of the characterological makeup of the person (incorporated). Going from retrospective to anticipatory to incorporated excuses, it is concluded that the role of nonverbal factors increases. Likewise, in the progression from making to being the excuse, it is argued that self- and other-deception also become more pervasive.  相似文献

It was tested whether professional actors would be able to communicate emotional meaning via facial expression when this is presented to judges without context information. Forty takes were selected from movies, depicting a female or a male actor in close-up showing facial expression. These close-ups were selected by two expert judges, who knew the complete movie and had to agree on the emotion expressed or expected to be expressed by the female or male actor in the respective take. Five takes each were selected to represent the basic emotions of joy, sadness, fear, and anger. Twenty takes each were selected showing female and male actors. These 40 takes (edited in random order onto video tape) were presented to 90 judges (about half female and half male; about half younger pupils and about half older ones), whose task it was to judge the emotion(s) expressed on nine 5-point-emotion scales. Results indicated that female actors are somewhat better (though not statistically significant) in communicating emotion via facial expression without context than male actors are. Furthermore, significant interactions between portrayed emotion and gender of actors were found: While recognition rate for joy is very high and identical for both genders, female actors seem to be superior in communicating fear and sadness via facial expression, while male actors are more successful in communicating anger. A display rule approach seems to be appropriate for the interpretation of these results, indicating that gender-specific attempts to control/inhibit certain emotions do not only exist in real life, but also in movies.The research reported here was supported by a grant of the Deutsche Forschungsgemeinschaft (WA 519/2-2). I thank Uwe Balser and Tina Mertesacker for their help in selecting the stimuli, preparing the judgment tapes, recruiting subjects and conducting the study.  相似文献

A face-to-face survey conducted in 1984 with a sample of 1491residents of the Detroit metropolitan area (including an oversampleof older adults) and a reinterview of a random subset of theserespondents by telephone were used to compare the two modesof data collection across two age levels. Except for a tendencytoward a disproportionately large number of DK answers and adisproportionately large amount of interviewer assistance onthe telephone, respondents 60 years of age and older did notexhibit larger mode differences than did respondents under 60.For both age groups, response distributions were rather similar,suggesting little effect of mode. Likewise, response style differedlittle by mode, while a higher proportion of missing data (i.e.,"I don't know" answers) was given on the telephone. The responserate for the telephone reinterview was 90%, somewhat lower forolder than younger persons. The findings support the feasibilityof using the telephone for reinterviewing older adults.  相似文献

In a six-year study on a locked psychiatric hospital unit for adolescents, first patients and then their families became integrated into the interdisciplinary treatment team. The results were universally beneficial. After initial resistance and some fine tuning of their skills, the staff became strong supporters of the program. Parents, no longer one down, developed a close working relationship with the therapists and milieu staff. Treatment planning and implementation was enriched by the interaction and dissension was minimized. Most important of all, the adolescents improved more rapidly and hospital stays were significantly shortened.  相似文献
