It has been argued that “paternalistically motivated forced savings constitutes an important, and to some the most important, rationale for social security retirement systems.” This paper revisits the role played by myopia in generating a theoretical rationale for pay-as-you-go (PAYG) social security in dynamically efficient economies. If the competing asset is linear storage and myopic agents are allowed to borrow against future pension benefits, there is no welfare-rationale for PAYG pensions. Sufficiently strong myopia may justify such pensions only if agents cannot borrow against their future pension, but then they are at a zero-saving corner. With enough myopia, co-existence of positive optimal pensions and positive private saving is possible if the return to saving declines with saving, as in a model with a neoclassical technology.  相似文献

Objective: To assess long-term healthcare costs related to ischemic stroke and systemic embolism (stroke/SE) and major bleeding (MB) events in patients with non-valvular atrial fibrillation (NVAF) treated with non-vitamin K antagonist oral anticoagulants (NOACs).

Materials and methods: Optum’s Clinformatics Data Mart database from 1/2009–12/2016 was analyzed. Adult patients with ≥1 stroke/SE hospitalization (index date) were matched 1:1 to patients without stroke/SE (random index date), based on propensity scores. Patients with an MB event were matched to patients without MB. All patients had an NOAC dispensing overlapping index date, ≥12?months of eligibility pre-index date, and ≥1 NVAF diagnosis. The observation period spanned from the index date until the earliest date of death, switch to warfarin, end of insurance coverage, or end of data availability. Mean costs were evaluated: (1) per-patient-per-year (PPPY) and (2) at 1, 2, 3, and 4?years using Lin's method.

Results: The cost differences were, respectively, $48,807 and $28,298 PPPY for NOAC users with stroke/SE (n?=?1,340) and those with MB (n?=?3,774) events compared to controls. Cost differences of patients with vs without stroke/SE were $49,876, $51,627, $57,822, and $60,691 at 1, 2, 3, and 4?years post-index, respectively (p?p?Limitations: Limitations include unobserved confounders, coding and/or billing inaccuracies, limited sample sizes over longer follow-up, and the under-reporting of mortality for deaths occurring after 2011.

Conclusions: The incremental healthcare costs incurred by patients with vs without stroke/SE was nearly twice as high as those of patients with vs without MB. Moreover, each additional year up to 4?years after the first event was associated with an incremental cost for patients with a stroke/SE or MB event compared to those without an event.  相似文献

Strategic niche management (SNM), a tool to understand and manage radical socio-technical innovations and facilitate their diffusion, has always departed from a technical artefact. Many radical innovations, however, do not revolve around such an artefact. Social entrepreneurship is a new business model that combines a social goal with a business mentality and is heralded as an important new way to create social value such as sustainability. This study examines if and how SNM can be applied to such a social innovation. It identifies theoretical and practical limitations and proposes solutions. The main conclusion is that SNM can be used to analyse radical social innovation, although it requires rethinking the initial entry point for research and management. Exemplifying quotes are proposed as an alternative. Second, this paper suggests using values to describe niche–regime interaction as a better way to anticipate future niche–regime interactions.  相似文献

1871 saw the publication of two major treatises in economics, with self-seeking economic man at their center. In the same year Darwin published The Descent of Man, which emphasized sympathy and cooperation as well as self-interest, and contained a powerful argument that morality has evolved in humans by natural selection. Essentially this stance is supported by modern research. This paper considers the nature of morality and how it has evolved. It reconciles Darwin’s notion that a developed morality requires language and deliberation (and is thus unique to humans), with his other view that moral feelings have a long-evolved and biologically-inherited basis. The social role of morality and its difference with altruism is illustrated by an agent-based simulation. The fact that humans combine both moral and selfish dispositions has major implications for the social sciences and obliges us to abandon the pre-eminent notion of selfish economic man. Economic policy must take account of our moral nature.  相似文献

Quality assurance is an important responsibility of those who purchase managed vision care benefits. In conducting a quality assurance program, it is important to respect patient confidentiality and the practitioner's right to exercise professional discretion. An effective program will not only accomplish its main objective of attaining high-quality care, but it can also enhance member satisfaction and improve provider relations.  相似文献

Regulatory incentive policies and abuse   总被引:1,自引:0,他引:1  
We examine the incentives for abuse under rate-of-return (ROR) and incremental surplus subsidy (ISS) regulation. Abuse consists of expenditures by the regulated firm that provide private benefits, but do not reduce production costs. We show that ISS regulation provides efficient incentives for owners of the regulated firm to limit abuse by subordinates. We also prove that abuse by owners of the firm will generally be greater (smaller) under ROR regulation than under ISS regulation when consumer demand for the regulated product is inelastic (elastic). Furthermore, we show that to limit abuse and improve welfare under ROR regulation, it can be advantageous to ignore available information about consumer demand.  相似文献

Perceptions of risks from two groups of industrial radiographers, one from Hungary, (n = 45) and from the United Kingdom, (n = 29) were compared by the psychometric method. The comparison was made because both groups were at risk for high doses of ionizing radiation. We found the groups had similar demographic profiles but poor socio-economic conditions of Hungarians were associated with higher levels of emotional distress. Correlation HU-UK for personal and general risks were at a significant level for topics that included lifestyle and radiation risks. Perceptions of risks from radiation were small except for large personal risk from East European nuclear power plants. Knowledge of radiation risk intranationally was correlated positively with personal risk for UK radiographers and negatively for Hungarians. However, average overall risk perceptions from the same topic list for all radiographers did not differ significantly from a group (n = 1461) of UK citizens, though radiographer's risks from radiation were considerably greater. As a new lifesaving intervention it was proposed that radiation risk reduction could be achieved by genetic testing.  相似文献
