Private Health Insurance Incentives in Australia: The Effects of Recent Changes to Price Carrots and Income Sticks
Full text linkThree major policy tools govern the demand for private health insurance (PHI) in Australia: premium-related subsidies (i.e. PHI-rebate); income tax surcharges (i.e. the Medicare Levy Surcharge (MLS)); and lifetime community-rating (i.e. Lifetime Health Cover). The first two provide a system of "carrots and sticks" to create incentives for increasing the demand for PHI. The third creates incentives for consumers to purchase PHI earlier than they otherwise would have, and to maintain this coverage over time even when prices rise. This paper makes a number of contributions to the existing literature. We develop a diagrammatic model that incorporates income heterogeneity and use it to consider two important policy issues: the effect of policy changes on consumer price responsiveness, and the effect of policy changes on the PHI take-up rates. The model suggests that recent changes to the income tax surcharge are likely to reduce the price elasticity of demand for insurance, which could have further consequences for outcomes in the PHI market and the health system more generally. Increases in premiums will reduce take-up, but could worsen the government's budget position, even if tax revenues were to rise. Finally, we conduct numerical simulations to examine the possible effects of recent policy changes, which are aimed at further means-testing the PHI rebate and the MLS. The simulation results suggest that these recently adopted policy changes are likely to reduce the take-up of PHI as well as consumers' responsiveness to future premium increases
The analytics of the Australian private health insurance rebate and the Medicare levy surcharge
No full textThis paper presents an analytical framework for examining changes in the Private Health Insurance rebate (PHIR) and the Medicare Levy Surcharge (MLS), and uses it to establish three key propositions. First, increases in the MLS rate tend to reduce the elasticity of demand for private health insurance. Second, simultaneously increasing MLS rates and thresholds has a theoretically ambiguous effect on PHI take-up rates. Third, means testing the PHIR can never increase PHI take-up, and will reduce it in some circumstances. The paper concludes with a discussion of the possible consequences of recently proposed policy changes to private health insurance in Australia
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
