We show that the optimal prize structure of symmetric n-player Tullock tournaments assigns the entire prize pool to the winner, provided that a symmetric pure strategy equilibrium exists. If such an equilibrium fails to exist under the winner-take-all structure, we construct the optimal prize structure which improves existence conditions by dampening efforts. If no such optimal equilibrium exists, no symmetric pure strategy equilibrium induces positive efforts. 相似文献

For decades, policymakers have discussed how to remedy the high poverty rates of older widows. Yet older divorced women are more likely to be poor than older widows, and historical divorce and remarriage trends suggest that in the future a larger share of retired women will be divorced. This article uses the Social Security Administration's Modeling Income in the Near Term (version 6) to project the retirement resources and wellbeing of divorced women. We find that Social Security benefits and retirement incomes are projected to increase for divorced women and that their poverty rates are projected to decline, due in large part to women's increasing lifetime earnings. However, not all divorced women will be equally well off economic well-being in retirement varies by Social Security benefit type. 相似文献

Women's labor force participation and earnings dramatically increased after World War II. Those changes have important implications for women's Social Security benefits. This article uses the Social Security Administration's Modeling Income in the Near Term (version 6) to examine Social Security benefits for current and future beneficiary wives. The projections show that fewer wives in more recent birth cohorts will be eligible for auxiliary benefits as spouses because their earnings are too high. If their husbands die, however, most wives will still be eligible for survivor benefits because, despite the increase in their earnings over time, they still typically have lower earnings than their husbands. Even so, the share of wives who would be ineligible for widow benefits is projected to double between cohorts. 相似文献

Blacks, Hispanics, and divorced women have historically experienced double-digit poverty rates in retirement, and divorce and other demographic trends will increase their representation in future retiree populations. For these reasons, we might expect an increase in the proportion of economically vulnerable divorced women in the future. This article uses the Social Security Administration's Modeling Income in the Near Term (version 6) to describe the likely characteristics, work experience, Social Security benefit status, and economic well-being of future divorced women at age 70 by race and ethnicity. Factors associated with higher retirement incomes include having a college degree; having a strong history of labor force attachment; receiving Social Security benefits; and having pensions, retirement accounts, or assets, regardless of race and ethnicity. However, because divorced black and Hispanic women are less likely than divorced white women to have these attributes, income sources, or assets, their projected average retirement incomes are lower than those of divorced white women. 相似文献

We investigate how material and symbolic campaign appeals may motivate segments of the electorate to be more engaged with
the unfolding presidential campaign; this engagement is a first step toward bringing these populations into an electoral coalition.
We pair two massive new data collections—the National Annenberg Election Study capturing public opinion across an entire campaign
and The Wisconsin Advertising Project recording and cataloging the political commercials aired by campaigns—to examine how
the candidates’ choice of issues affects who gets into the game. We find evidence that appeals to symbolic interests are more
likely than appeals to material interest to selectively engage targeted groups. 相似文献

On 15 March 2012 the European Court of Human Rights (the Court) issued its first judgment addressing the differential treatment of same‐sex and opposite‐sex couples in respect of the adoption of a child. 1 The Court held that excluding same‐sex couples in civil partnerships, who have no legal right to marry, from adoption provisions available to married opposite‐sex couples does not violate rights guaranteed by the European Convention on Human Rights (the Convention). I argue that the Court's reasoning in Gas and Dubois v France is unpersuasive and unsustainable in light of its wider case law. 相似文献

Surface coatings that can help deter and solve gun crime are described. These nanoengineered coatings have been applied and evaluated on brass cartridge cases, where they increase associative forensic evidence through nanotag donation to the handler and the retention of handler's DNA. In future we expect this approach to be used for other surfaces and conditions. 相似文献

Pearson correlation coefficients were applied for the objective comparison of 30 black gel pen inks analysed by laser desorption ionization mass spectrometry (LDI-MS). The mass spectra were obtained for ink lines directly on paper using positive and negative ion modes at several laser intensities. This methodology has the advantage of taking into account the reproducibility of the results as well as the variability between spectra of different pens. A differentiation threshold could thus be selected in order to avoid the risk of false differentiation. Combining results from positive and negative mode yielded a discriminating power up to 85%, which was better than the one obtained previously with other optical comparison methodologies. The technique also allowed discriminating between pens from the same brand. 相似文献
