Empirical applications of poverty measurement often have to deal with a stochastic weighting variable such as household size.
Within the framework of a bivariate distribution function defined over income and weight, I derive the limiting distributions
of the decomposable poverty measures and of the ordinates of stochastic dominance curves. The poverty line is allowed to depend
on the income distribution. It is shown how the results can be used to test hypotheses concerning changes in poverty. The
inference procedures are briefly illustrated using Belgian data.

Violations of dominance in pricing judgments 总被引:1,自引:1,他引:0
The dominance principle states that the judged price of gamble A should be equal to or greater than the judged price of gamble B whenever A's outcomes are equal to or better than the corresponding outcomes of B, holding everything else constant. Subjects often violate the dominance principle by assigning a higher price to a gamble with some probability of winning a positive amount, Y, otherwise zero, than to a superior gamble with the same chances of winning Y, otherwise winning X. Violations also occur with losses. Results are consistent with a configural-weight theory in which the decision weight for each outcome depends on the rank of the outcome with respect to the other outcomes in the lottery and the value of the outcome (zero vs. nonzero).The authors thank Shi-jie Chang, Duncan Luce, and Lisa Ordóñez for comments on an earlier draft.

Stochastic dominance is usually used to rank random variables by comparing their distributions, so it is widely applied in economics and finance. In actual applications, complete stochastic dominance is too demanding to meet, so relaxation indexes of stochastic dominance have attracted more attention. The π index, the biggest gap between two distributions, can be a measure of the degree of deviation from complete dominance. The traditional estimation method is to use the empirical distribution functions to estimate it. Considering the populations under comparison are generally of the same nature, we can link the populations through density ratio model under certain condition. Based on this model, we propose a new estimator and establish its statistical inference theory. Simulation results show that the proposed estimator substantially improves estimation efficiency and power of the tests and coverage probabilities satisfactorily match the confidence levels of the tests, which show the superiority of the proposed estimator. Finally we apply our method to a real example of the Chinese household incomes. 相似文献

ABSTRACTMalaysia is one of the multi-ethnic, multi-cultural and multi-religious countries in Southeast Asia. Due to the pluralistic nature of Malaysia, it has a political structure based on ethnic politics. The ethnic preferential policies affected most domains of this country. The objective of this article is to examine the origin and background of ethnic politics in Malaysia. Findings of this study indicate that, ethnic politics originated during the British colonial period, it became a tool used by the Barisan Nasional for the legitimacy of regime. Moreover, ethnic politics in Malaysia today is intertwined with religion. Besides, there is the dilemma of the choice between the interest of certain ethnic group and national interests. However, with the opposition coalition Pakatan Harapan won the election in 9th May, UMNO-led BN lost power and interrupted its 61 years control, which leaves us an interesting topic to think about the future of Malaysian ethnic politics. 相似文献

This paper investigates the individual and combined factors affecting the extent to which corporations respond to crisis events consistently, in a timely manner, and actively. The determinants examined include public relations autonomy, legal dominance, strategic orientation, and organizational factors. A survey was conducted of communications mangers, public affairs personnel, and public relations personnel, drawn from the top 500 companies operating in Taiwan. Results indicate that the relative effect of individual sources of influence on crisis response is greatest for situations in which public relations departments have the most autonomy, followed by those where crisis management is handled with a strategic orientation, those where the legal departments dominate, and those where organizational factors provide the main avenue of address. The results emphasize the intriguing role of public relations autonomy by demonstrating its significant impact on providing a consistent, timely, and active crisis response. The strategic orientation of situation analysis also predicts a consistent response, whereas legal dominance predicts strategic ambiguity or inconsistent communication. 相似文献

Dominance hierarchies play an important role in governing the social interactions of humans and other species of social animals. In a social group, dominance relations can be inferred from the directed network of matchups between actors. Methodologists have proposed different ways to measure social dominance in directed networks. One such measure, the “β-measure” (van den Brink and Gilles, 2000), emphasizes the quality of defeated opponents in a way that an actor is seen as being more dominant when s/he defeats opponents who are more rarely defeated. While insightful in theory, the validity of the measure in people’s perception remains questionable, considering the cognitive complexity imposed by this measure, compared to a simpler measure that merely counts the number of defeated opponents. We conducted a vignette experiment with human subjects (professional athletes) to test their judgments of the dominance relation in a hypothetical tournament. Fitting our parametric model to peoples’ evaluations in the experiment, we found strong evidence in support of the β-measure: Although, in general, contestants who win more in the tournament are regarded as being more dominant, the contents of the winning records matter, such that those who beat more victorious opponents are further regarded as more dominant than those who defeat less victorious opponents. We also found a gender difference, in that men have a stronger propensity than women to adopt the β-measure when judging social dominance. 相似文献

This mixed-methods study of BDSM investigates the nuances of BDSM participants’ role identities, role frequencies, and role fluidities—shifts in identities and play across time, location, scene, and play partner. Data were gathered from 202 online surveys and 25 semistructured interviews about participants’ roles given their gender and sexual identities. These data reveal that men tend to self-identify as Dominant, Master, Top, or Sadist (DMTS) and always perform dominant roles, while women tend to self-identify as Submissive, Slave, Bottom, or Masochist (SSBM) and always perform submissive roles. Although this would seem to support the theory that BDSM reinforces gendered dominant/submissive binaries, further analyses indicate that women and queer/pansexual individuals disrupt this binary through their Switch identities and roles. Switching and queer identities, thus, offer the possibility for transforming dominant/submissive and other binaries. 相似文献
