When the billing of local telephone service is changed from flat rate to measured service, the distribution of monthly calling rates is altered. This paper models the distribution of flat-rate telephone use in terms of demographic variables and stochastic components; the shift to measured service affects both the systematic and stochastic parameters. The model is fitted by maximum likelihood to data for interviewed households participating in General Telephone's local-measured-service experiment in Illinois. Households tend to make more calls if they are larger (more people), older, or include teenagers. They tend to reduce calling proportionately more in response to usage charges if they average many calls under flat rate for any of the above reasons or for other, unexplained reasons. There is substantial variation in telephone use by households with similar demographic characteristics. Consequently, the benefits and costs of local measured service will tend to be diffused across demographic groups.  相似文献

This paper uses a recently-developed technique, calledgenerational accounting, to assess New Zealand's long-term fiscalposition. Generational accounting has become a popular alternativeto traditional deficit accounting, because it provides a moreaccurate picture of the intergenerational distribution of fiscalburdens and the associated macroeconomic effects, particularlyin the presence of demographic transitions and large unfundedpublic transfer programs. Past studies have suggested the existenceof significant generational imbalances in several countries.We find that behind New Zealand's projectedbudget surpluses, there is indeed a sound fiscal picture. Evenunder the base case scenario, which entails substantial short-runtax reductions, the burden on future generations (relative toincome) is projected to fall slightly below that on current newborns.New Zealand appears to have avoided the large fiscal imbalancesplaguing the United States and other OECD countries not by placinglarge tax burdens on young current generations, but by limitingthe size of its commitments.  相似文献

Since 1971 Australian governments have varied expenditure on labour market programs and education. This article attempts to explain these changes in the context of several straightforward hypotheses concerned with political processes. In both policy areas the evidence is generally consistent with four views: that ALP governments spend relatively more than coalition governments; that ALP expenditure is more likely to be directed to the public sector, and coalition expenditure to the private sector; that governments of both political persuasions tend to move towards their opponents' position in budgets immediately preceding elections; and that, after the marked changes initiated in the 1972 to 1974 period, the parties have become increasingly similar in expenditure terms. Apparently there have been important differences between the political parties in government, but these distinctions have become less clear–cut over recent years.  相似文献

An economy may remain robust in the face of efficiency-inhibiting state-made rules if individuals are able to establish effective sources of credibility that do not rely on the state. After explaining how non-state sources of trust and private recourse evolve to enhance credibility, examples of contracting around undesirable rules in United States are discussed. The potential for contractual nullification varies considerably, however, in part because of state action that limits civil-society and/or market activities. In many less robust economies, there are even more significant barriers to building private sources of trust and recourse, undermining the potential for contractual nullification.

Organizational citizenship behavior (OCB) has been associated with positive organizational outcomes and with higher managerial ratings of employee performance. However, concerns have been raised about the possible personal costs of performing such activities. This paper examines the relationship between OCB and emotional exhaustion and work‐family conflict and explores the moderating role of job performance in shaping those relationships. In a time‐lagged field study of customer‐contact center employees the research found that one particular dimension of OCB—conscientiousness—was associated with higher emotional exhaustion and with work‐family conflict. The study also revealed that conscientious employees who performed their in‐role job responsibilities at a high level experienced greater emotional exhaustion and work‐family conflict than conscientious employees who performed their in‐role job responsibilities at a low level. Our findings suggest that organizational pressures to increase the level at which both discretionary and formal role obligations are performed can carry negative consequences for employees. © 2016 Wiley Periodicals, Inc.  相似文献

Background:

While literature has focused on the impact of bleeding beginning outside the hospital setting among patients with atrial fibrillation (AF), there is little information regarding bleeding that first occurs within a hospital setting. This study was performed to determine the association between hospital-associated bleeding in patients admitted for AF on outcomes of length of stay (LOS) and total hospitalization cost.

Methods and results:

The Premier research database was queried to identify adult inpatients discharged between 2008–2011 having a primary diagnosis code for AF where a bleeding diagnosis code was not present on admission. Regression was used to adjust for baseline differences in patients to estimate outcomes comparing patients with and without a hospital-associated bleed. There were 143,287 patients that met the study criteria. There were 2991 (2.1%) patients identified with a hospital associated bleed. After adjustment for covariates, the mean estimated LOS was significantly greater in the bleed group, at 6.0 days (95% CI?=?5.8–6.1) vs the no bleed group at 3.3 days (95% CI?=?3.3–3.3) (p?<?0.0001). Similarly, the adjusted mean estimated total hospitalization cost was also significantly greater in the bleed group, $12,069 (95% CI?=?$11,779–$12,366) vs $6561 (95% CI?=?$6538–$6583) in the no bleed group (p?<?0.0001).

Conclusions:

After adjustments for baseline differences the data show that the 2.1% (n?=?2991) of patients with hospital associated bleeding accounted for an estimated additional 8106 hospitalization days and $16.4 million dollars in cost over the study period compared to non-bleeders.  相似文献

The reliability of BEA’s estimates, as measured by the magnitude and pattern of revisions, is highly important to economic policy-making and business decisions. We find evidence that the revisions are partially predicable using contemporaneously available information for the current quarterly estimates of GDP. Information about national income is found to significantly supplement the information found in the final current quarterly estimates of GDP in explaining the revisions to the latest-available estimates of GDP. However, there is little evidence of the predictability of revisions in GDI or national income. Finally, both the advance and final current quarterly estimates are found to do a reliable job of measuring GDP and GDI around cyclical peaks, but a less reliable job around cyclical troughs, the declines preceding the troughs are overstated and the upturns after the troughs are understated. An earlier and somewhat expanded version of this paper, “Revisions, Rationality, and Turning Points in GDP,” was presented at the session “Tracking the Turning Points in the Economy,” AEA meetings January 3–5 2003, Washington DC. It is available in the “working papers” section of BEA’s web site, www.bea.gov  相似文献

According to many managers, the Sarbanes-Oxley Act of 2002 caused the costs of being public to increase. Subsequently, following the Act, many firms went private rather than incur the costs. We investigate the differences in the financial characteristics of firms that went private between 1998 and 2003 and a control sample of firms which went public and did not go private Our results indicate that there are differences in the two groups, as well as differences in firms that went private prior to and following Sarbanes-Oxley. Taken together, our results are indicative of going private to avoid the higher costs of being public post Sarbanes-Oxley.  相似文献

Inadequate attention has been given to labor-management relations in health care organizations. Bacause of the labor-intensive nature of health care and the great dependence on human resources, health services researchers should place greater emphasis on labor-management issues. This article develops a framework and suggests methodologies for examining labor relations in health care organizations. Specifically, six cirtical issues are suggested for attention by researchers: (1) the quality of the union-management relationship; (2) union organizing drives; (3) collective bargaining and contract negotiations; (4) impasse resolution; (5) contract administration and grievance handling; and (6) labor-management cooperation. These areas of research have been dominated by industrial relations researchers who have focused primarily on the manufacturing sector. Given cost containment and competitive pressures, it is timely to bridge the gap between the health services research community and the accumulating body of knowledge in industrial relations.  相似文献
