This study estimates the effect of local labor demand on the likelihood that Supplemental Nutrition Assistance Program (SNAP) beneficiaries are able to transition out of the program. Our data include SNAP administrative records from New York (2007 to 2012), linked at the person‐level to the 2010 Census, and linked at the county‐month‐level to industry‐specific labor market conditions. We find that local labor markets matter for the length of time spent on SNAP, but there is substantial heterogeneity in estimated effects across local industries. Using Bartik‐style instruments to isolate the effect of labor demand and controlling for the changing composition of entrants and program rules brought on by the Great Recession, we find that fluctuations in labor demand in industries with high shares of SNAP participants—especially food service and retail—change the likelihood of exiting the program. Notably, estimated industry effects vary across race and parental status, with black participants being most sensitive to changes in local labor market conditions and mothers benefiting less from growth in local labor demand than fathers and non‐parents. We confirm that our results are not driven by endogenous inter‐county mobility or New York City labor markets and are robust to multiple specifications.  相似文献

Bayes factors quantify the evidence in support of the null (absence of an effect) or the alternative hypothesis (presence of an effect). Based on commonly used cut‐offs, Bayes factors between 1/3 and 3 are interpreted as evidentially weak, and one typically concludes there is an absence of evidence. In this commentary on Warmelink, Subramanian, Tkacheva, and McLatchie (Legal Criminol Psychol 24, 2019, 258), we discuss how a Bayesian report can be made more informative. Firstly, this implies a departure from the labels provided by commonly used cut‐offs when reporting Bayes factors. Instead, we encourage researchers to report the value of the Bayes factors, or to convert these values into nominal support for the hypotheses. Secondly, researchers can provide recommendations to design follow‐up studies by examining the posterior distribution of the magnitude of the effect size. Lastly, we show how individual Bayes factors can be evaluated in the context of large‐scale meta‐analyses.  相似文献

Studies of “waves” of regime change, in which large numbers of countries experience similar political transitions at roughly similar periods of time, though once popular, have fallen from favor. Replacing the “third wave” arguments are several competing models relating domestic social structure—specifically, the distribution of income and factor ownership—to regime type. If any of these distributive models of regime type is correct, then global trade has an important explanatory role to play. Under factor‐based models, changes in the world trading system will have systematic effects on regime dynamics. Trade openness determines labor's factor income and ultimately its political power. As world trade expands and contracts, countries with similar labor endowments should experience similar regime pressures at the same time. We propose a novel empirical specification that addresses the endogeneity and data‐quality problems plaguing previous efforts to examine these arguments. We investigate the conditional impact of the global trading system on democratic transitions across 130 years and all of the states in the international system. Our findings cast doubt on the utility of factor‐based models of democratization, despite their importance in fueling renewed interest in the topic.  相似文献

In the 1990s, strong incentives for managed care organizations to control costs, once regarded as a fortuitous confluence of interests, came to be seen as antithetical to consumers' interests in quality of care. In response to this change in political climate, many states have greatly increased their regulatory control of managed care organizations since the mid-1990s. This activity is surprising in an era when public policy on health care issues is usually described as frozen, gridlocked, and/or stalemated as a result of intense activity on the part of organized interests. We take advantage of the variation in state regulations of health maintenance organizations (HMOs) to discover why some governments are able to address policy problems that are often perceived as intractable in a political if not in a true policy sense. From the history of HMOs, the backlash against managed care, and state responses to that backlash, we first extract a number of hypotheses about state regulatory activity. We then test these hypotheses with data on regulatory adoptions by states during the late 1990s and the early 2000s. Last, we discuss the findings with special attention to the role of politics in health care.  相似文献

ABSTRACT

This article argues that Karl Marx and Friedrich Engels’s theory of history contained racist components. In Marx and Engels’s understanding, racial disparities emerged under the influence of shared natural and social conditions hardening into heredity and of the mixing of blood. They racialized skin-colour groups, ethnicities, nations and social classes, while endowing them with innate superior and inferior character traits. They regarded race as part of humanity’s natural conditions, upon which the production system rested. ‘Races’ endowed with superior qualities would boost economic development and productivity, while the less endowed ones would hold humanity back. Marxist race thinking reflected common Lamarckian and Romantic-Nationalist assumptions of the era.  相似文献

As the sharing economy continues to grow and diversify, various institutes and members of government are contemplating the need for new employment regulations, including those related to portable benefits. However, there has been no known inquiry into this issue with those U.S. workers in the sharing economy. This paper presents exploratory research on the subject of portable benefits for workers engaged in the sharing economy and is intended to inform the development of future research questions and to determine the best research design and data collection method for a more extensive study. Arguably, rideshare drivers represent a large constituency of sharing economy workers in the United States and were utilized as the study population. Through authorized access to closed social media sites, this study explored the desire among rideshare drivers for portable benefits, how these benefits should be funded, and how such programs would be administered. The findings indicate that the majority of respondents were interested in the availability of portable benefits, although the preference for specific benefits varied widely among respondents. More than half believe companies, along with workers, should fund these benefits, and slightly less than half believe private sector third parties like insurance companies should administer these programs. However, given the transient nature of this workforce, administering such programs could prove to be quite challenging for organizations and plan administrators alike.  相似文献

By using the Hirschman-Herfindahl index (HHC) the traditional approach to the tax complexity hypothesis introduces a restriction into the fiscal illusion model which has no theoretical foundation. We analyse the existing framework of the tax complexity hypothesis in detail and propose to capture this complexity through a Hannah and Kay index. We extend the theoretical framework by considering the expected return on investment in information. The empirical tests show that the HHC overestimates the importance of size inequalities between different taxes, while underestimating the impact of the number of taxes as a source of informational costs. The expected revenue hypothesis is not supported.  相似文献

This article discusses the development of Transcaucasian social-democratic terrorism from 1901 to 1909. For two reasons the ‘psychohistorical’ model emphasising the subjective and irrational aspects of terrorism has only limited value for the Transcaucasian case. First, the significance of the contextual factor is powerfully underscored by the phenomenon of workers' ‘economic terrorism’. It was not uncommon even, for workers to blackmail reluctant party organisations into supporting the killing of their enemies. Secondly, the social democrats were not driven by irrational urges but followed a rationally motivated and selective terrorist strategy. They attempted to limit or prevent workers' terrorism from below, the ‘anarchist’ potential of which they considered a threat to the organised mass struggle. They set their hopes on a division of labour, with a militant but mostly peaceful workers' movement and terrorism as the prerogative of the party.  相似文献
