This paper presents up-to-date estimates of the ability of non-resident fathers to pay child support. While no nationally representative data exist on the incomes of fathers, this issue has become more pertinent in recent years, as child support has become an important national issue. We find that fathers on average are able to pay nearly five times more in child support than they currently pay, and also that low income fathers can afford to pay substantially more than they actually pay. We also find that changes in nonmarital childbearing and the returns to education have had only minimal effects on trends in fathers' incomes.  相似文献

Regression analysis was used to determine the significant determinants of aggregate merger activity before and after 1950. This study found that stock prices were positively related to merger activity both before and after 1950. However, interest rates were positively related to merger activity prior to 1950, and negatively related to merger activity after 1950. This may have been the result of the Treasury Accord of 1951, which stopped pegging of interest rates. The unemployment rate was negatively related to mergers before 1950, but insignificantly related to mergers after 1950. The decreased significance of the unemployment rate could be the result of the passage of the Celler-Kefauver amendment to the Clayton Act. Tightened regulation may have caused businesses to take a longer run view of merger activity and decreased the business cycle effect. In conclusion, changes in both the regulatory environment and monetary policy have influenced the level of merger activity since 1950.  相似文献

There has been considerable debate as to whether job stability has declined in the United States. This paper uses data from the Survey of Income and Program Participation (SIPP) to examine the incidence of labor market turnover between 1986 and 1993. Specifically, we calculate one- and two-year separation rates and then analyze turnover by the source of separation. We find that the incidence of job separations did not increase over the period under investigation, but appears to have declined somewhat. When analyzing separations by reason, conditional on separating from an employer, we find little evidence of temporal changes in the composition of turnover that would indicate greater employment instability. Therefore, we do not find conclusive evidence that employment relationships have become more unstable in the recent past.   相似文献

We extend prior research on the empirical properties of daily trading volume and methods to detect abnormal trading volume in two ways. We compare the performance of a nonparametric test statistic with the parametric test statistic used in prior research and we study samples of NASDAQ securities as well as samples of NYSE/ASE securities. Prior research has focused exclusively on NYSE securities. We find the nonparametric test statistic is more powerful in detecting abnormal trading volume than the parametric test statistic in both samples of NYSE/ASE and NASDAQ securities. We also document that abnormal trading volume will be detected more often in samples of NYSE/ASE securities compared to NASDAQ securities.  相似文献

Because of the inconsistency in the findings from past decades of research and the lack of consensus regarding the relationship between advertising exposure and cigarette consumption, the large body of extant research on the effectiveness of cigarette advertising has generated equivocal conclusions on this subject. Therefore, we conducted a comprehensive meta-analysis of cigarette advertising research to determine what impact, if any, cigarette advertising has on cigarette consumption. Unlike previous attempts to synthesize the cigarette advertising literature, this study examined three specific levels of the criterion (i.e., initiation, continuation, and brand behavior) rather than examining only aggregate consumption.  相似文献

This paper discusses how instructors can engage their students in community-based participatory research (CBPR) projects that involve not only research on a topic but also include community stakeholders in the research process and provide opportunities for service learning. CBPR is defined, examples of effective CBPR student projects are presented, the possible benefits and drawbacks of CBPR student projects are offered, and tips for conducting successful CBPR projects with hospitality and tourism students are provided.  相似文献

The existing state of sanitation in developing Asian countries fails to deliver a level of service that is adequate for meeting the human right to a standard of living consistent with dignity and health, or for sustaining the capacity for future generations to have access to clean water resources and healthy ecosystems. We argue that translating the current neo-centralised technologies and institutional arrangements mainstreamed by industrialised countries would not resolve the problem in the context of developing countries. Instead it is necessary to ‘leap frog’ to the emerging technological and institutional arrangements that are responsive to current needs and contexts and to potential risks. The sustainability focus and often decentralised technologies of this emergent stage in sanitation present many opportunities for new actors to enter the urban sanitation industry. At the same time, there are many barriers to entry, particularly from the perspective of conventional business management focused on increasing shareholder value.We propose that perspectives from the corporate social responsibility discourse have the potential to provide both the ‘pull’ for seizing the business opportunity for profit while serving social needs, and the ‘push’ to overcome the barriers in order to serve a wider social purpose for corporations. The wealth of nations, at least as reported in ubiquitous GDP terms, has greatly increased through the activities of corporations driven by a profit motive; but the increased poverty, injustice and ecosystem degradation that have resulted from economic activity suggest that corporations perhaps ought to have regard for broader concerns beyond shareholder value. We explore how the alternative relational view of a corporation, as a metaphorical person within society who adopts a moral code consistent with both Buddhist economics and Adam Smith's philosophy, may facilitate profitable corporations that provide better economic, ecological and social outcomes in serving the need for sustainable sanitation services in developing Asian countries.  相似文献

It is well documented that individuals do not spend the Supplemental Nutrition Assistance Program (SNAP) benefits smoothly over the month after receipt. Rather, recipients spend a disproportionate share of benefits at the beginning of the benefit month. This has costs for recipients and stores. There is also evidence that other income streams, such as Social Security and paychecks, are not spent smoothly. The presence of these other income streams may bias estimates of the effects of this SNAP cycle on consumption for working SNAP beneficiaries and those who receive other government benefits. We use data from United States Department of Agriculture's National Household Food Acquisition and Purchase Survey to explore how the SNAP cycle is affected by accounting for these other income streams. We find suggestive evidence that the cycle is more pronounced for workers who are paid on a weekly or monthly basis, but little evidence that cycles in other income streams mitigate or exacerbate the SNAP cycle.  相似文献

Using a contingency perspective and data from 122 CEOs of Spanish firms, this paper examines what makes a firm likely to adopt telecommuting. We hypothesized that employer adoption of telecommuting would depend on organizational constraints (age and size of the firm), the international composition of the workforce, and the top executives' leadership style. In turn, we argue that firms adopting telecommuting would emphasize outcome‐based control systems. Our empirical evidence showed that telecommuting correlated with small organizational size, a high proportion of international employees, and variable compensation. A contingent reward leadership style at the top moderated the effects of firm age and internationalization on the adoption of telecommuting. © 2009 Wiley Periodicals, Inc.  相似文献
