Modelling income group differences in the health and economic impacts of targeted food taxes and subsidies

Objective : To examine the effects, by income group, of targeted food taxes and subsidies on nutrition, health and expenditure in the UK.

Methods : A model based on consumption data and demand elasticity was constructed to predict the effects of four food taxation-subsidy regimens. Resulting changes in demand, expenditure, nutrition, cardiovascular disease (CVD) and cancer mortality were estimated.

Data : Expenditure data were taken from the Expenditure and Food Survey; estimates of price elasticities of demand for food were taken from a report based on the National Food Survey 1988–2000. Estimates of effect on CVD and cancer mortality of changing fat, salt, fruit and vegetable intake were taken from previous meta-analyses.

Results : (i) Taxing principal sources of dietary saturated fat is unlikely to reduce cardiovascular disease (CVD) or cancer mortality. (ii) Taxing ‘less healthy’ foods (defined by the WXYfm nutrient profiling model) could increase CVD and cancer deaths by 35–1300 yearly. (iii) Taxing ‘less healthy’ foods and subsidising fruits and vegetables by 17.5% could avert up to 2900 CVD and cancer deaths yearly. (iv) Taxing ‘less healthy’ foods and using all tax revenue to subsidize fruits and vegetables could avert up to 6400 CVD and cancer deaths yearly. Few obesity-related CVD deaths are averted by any of the regimens. All four regimens would be economically regressive and positive health effects will not necessarily be greater in lower-income groups where the need for dietary improvement is higher.

Conclusions : A targeted food tax combined with the appropriate subsidy on fruits and vegetables could reduce deaths from CVD and cancer.

Importance of terrestrial subsidies for estuarine food webs in contrasting east African catchments

Little is known on the degree to which terrestrial organic matter delivered to tropical estuaries contributes to estuarine consumers. Here, stable isotope analysis is used to constrain this contribution for contrasting east African estuaries whose catchments differ in relative C3/C4 vegetation cover. As these two types of vegetation differ strongly in δ13C, we anticipated that terrestrial subsidies would be reflected in a gradient in estuarine consumer δ13C values, following the relative importance of C3 (characterised by low δ13C) vs. C4 (characterised by high δ13C) cover. Five estuaries were sampled for aquatic biogeochemical parameters, primary producers and consumers of different trophic ecologies: the Zambezi (catchment with a C3/C4 cover of 61/39%) in Mozambique, the Tana in Kenya (36/64%) and the Betsiboka (42/58%), Rianila (85/15%) and Canal des Pangalanes (C3-dominated) in Madagascar. Sampling was done before and after the 2010/2011 wet season. There were positive relationships between the proportion of C4 cover in the catchment and turbidity, δ13CDIC, δ13CDOC, δ13CPOC and δ15NPN. There were also significant positive relationships between δ13CPOC and consumer δ13C and between δ15NPN and consumer δ15N for all consumer trophic guilds, confirming the incorporation of organic material transported from the catchments by estuarine consumers, and implying that this material is transported up to high trophic level fish. Bayesian mixing models confirmed that C4 material was the most important source for the highly turbid, C4-dominated estuaries, contributing up to 61–91% (95% CI) to phytodetritivorous fish in the Betsiboka, whereas for the less turbid C3-dominated estuaries terrestrial subsidies were not as important and consumers relied on a combination of terrestrial and aquatic sources. This shows that the ecology of the overall catchment affects the estuaries at the most basic, energetic level, and activities that alter the turbidity and productivity of rivers and estuaries can affect food webs well beyond the area of impact.

The organizational legitimacy of the Bauhaus

Gaining and maintaining organizational legitimacy can be a major issue
for social and political structures such as cultural organizations. Legitimacy, sometimes called credibility, brings with it access to resources needed for survival and development. Organizations without legitimacy tend not to be successful in attracting grants, subsidies, and sponsorships. Research suggests that legitimate organizations may be seen as valuable social structures (Hybels 1995; Suchman 1995) and come to be “taken for granted” as part of the social fabric. In this article, I explore organizational legitimacy using the framework of institutional theory. I first define legitimacy and then discuss the key concepts of organizational legitimacy. Next, I present a case study based on an art/craft/design school. The school, known as the Bauhaus, existed between 1919 and 1933 in three German cities—Weimar, Dessau, and Berlin. Deterministic views of the pre–World War II environment suggest that the Nazi party was responsible for the closure of the Bauhaus. I argue that other factors were apparent. The Nazi regime was becoming a significant force in the late 1920s, but the story of the Bauhaus becomes more complex when viewed under the rubric of arts management and organizational legitimacy. In this article, I discuss how the Bauhaus sought and managed legitimacy and the role that the state and other actors played in granting that legitimacy. In conclusion, I offer a summary of the relevance of legitimacy to contemporary arts organizations.

Access to breast prostheses via a government-funded service in Victoria, Australia

For many women, the only alternative to breast reconstruction following a mastectomy is to use external prostheses, which need replacing regularly at a cost of up to $395 per prosthesis. Commonwealth and state governments across Australia have responded to this need by providing subsidies to assist in the purchase of breast prostheses. However, current arrangements have been highly variable and sometimes difficult to access. As part of a larger review of breast pros-thesis services in Victoria, Australia, the aim of this research was to evaluate client satisfaction among Victorian women who accessed funds through the State Government's Aids and Equipment Program, compare the responses of the program service providers with the experiences of clients accessing funding, and identify opportunities to improve service provision.

Emotional turmoil at the Bauhaus : problems of internal and external legitimacy : an historical case study

Walter Gropius established the Bauhaus in Germany in 1919. The organization established one of the most important design movements of the twentieth century. The organization had a very brief existence and was fraught with disruptions and emotional turmoil. Despite the difficulties, Gropius managed to keep the organization alive long enough for its extraordinary creativity to be harnessed and developed. The organization closed in 1933, but by that time its legitimacy as a source of design and pedagogy was assured. Organizational survival is often dependent on government subsidies, support through sales, donations or sponsorships. A factor in attracting this support is the perceived legitimacy of the organisation. Legitimacy is defined as a degree of consensus that the meanings and behavior of an organisation are valid and desirable by society in
general. Legitimacy remains an undeveloped concept. This paper reviews relevant theories of legitimacy, considers the role of emotions in shaping legitimacy and the emotions evoked as legitimacy is negotiated by internal and external stakeholders. A historical case study of the Bauhaus provides the backdrop for portraying the focal role emotions can play in institutionalization. The paper concludes with a discussion of the lessons of legitimacy available to contemporary cultural organisations.

The privatisation of telecommunications services : comparison of the developed and developing countries

The telecommunication sector in most countries was managed by the government for a long period. Government provision led to poor delivery of services, poor cost recovery, heavy subsidies and pOOl' maintenance. Privatisation was adopted as a means of overcoming these problems in the telecommunications sector in most developing countries. However, the results were not as expected due to poor privatisations processes, absence of genuine regulatory structure and unnecessary interference from the government. Hence the teledensity, breakages, call completion times, and tariff levels have not improved significantly compared to the developed countries.

The potential for tobacco control to reduce PBS costs for smoking-related cardiovaccular disease

Objective: To estimate Pharmaceutical Benefits Scheme (PBS) subsidies for drugs to treat smoking-related cardiovascular disease (CVD) in 2001-02, and over the period of the government's Intergenerational Report (IGR), assuming current smoking prevalence rates and a 5% absolute reduction.

Design and setting: An Australian epidemiological study, using prescribing data, aetiological fraction methodology, and IGR trends.

Main outcome measures: Estimated smoking-related PBS subsidy costs in 2001-02 and predicted cumulative subsidies until 2041-42, under current and reduced smoking prevalence assumptions.

Results: The PBS costs of smoking-related CVD in 2001-02 were $126 million, 9.77% of the cost of drugs for CVD and 2.96% of total PBS subsidies. The cumulative difference in these costs over the 40-year period with a 5% drop in smoking prevalence was predicted to be $4.5 billion, a 17% reduction. The saving would be $1.14 billion discounting future costs at 5% per year.

Conclusions: Further investment in tobacco control interventions could curb the increasing cost of the PBS and contribute to government efforts to ensure the viability of Australia's healthcare-financing programs. The net present value of a campaign to reduce smoking prevalence was estimated at $1 billion, with an internal rate of return of 33%.

Price and subsidy policy on soil conservation: application to smallholder tea growers

The role of commodity prices and subsidies on the adoption of soil conservation has been widely debated yet is poorly understood. One reason for this is the complex nature of the relationship between soil loss and yield damage. This paper examines the effects of price and subsidy policy on adoption of soil conservation measures in tea lands in Sri Lanka. The soil conservation technologies considered are lateral drains, stone terraces and Sloping Agricultural Land Technique (SALT). The study uses a non-linear yield damage function to estimate tea yield loss due to soil erosion. The yield function is then used in conjunction with a simple analytical model to examine the effects of changes in price and subsidies
on the incentives to adopt various soil conservation technologies. When there is a yield increment with soil conservation, increases in both prices and subsidies are found to make soil conservation economically attractive.
