    The Samaritan’s Dilemma and public health insurance

    When the government cannot commit to withdraw from providing charity health care, as is the case when it faces the Samaritan's Dilemma, a pub- lic health insurance scheme can be Pareto improving. However, the large heterogeneity in the design of such schemes observed around the world begs the question of what characterizes the optimal public health insurance plan. In this paper, we examine the distortions created by three plans, nested in terms of the constraints they place on the individual's decision problem. We ¯nd that linking public health insurance bene¯ts to the use of a certain type of health care, such as treatment in public hospitals, creates incentives against the e±cient use of higher quality health care. When such constraint is lifted, but the public insurance scheme still determines a minimum level of coverage for each illness, ¯rst best e±ciency is achieved. It turns out that placing constraints in the form of minimum levels of coverage for each illness is necessary for e±ciency. Removing such constraint decreases the relative price of high quality care for a subset of illnesses, and leads to too much high quality care used in equilibrium. This analysis suggests that the widespread practice of determining illness by illness coverage in public health insurance systems has an e±ciency rationale, despite the administrative and informational di±culties that it entails.Samaritan's Dilemma, Health insurance.

    When the government cannot commit to withdraw from providing charity health care, as is the case when it faces the Samaritan's Dilemma, a public health insurance scheme can be Pareto improving. However, the large heterogeneity in the design of such schemes observed around the world begs the question of what characterizes the optimal public health insurance plan. In this paper, we examine the distortions created by three plans, nested in terms of the constraints they place on the individual's decision problem. We find that linking public health insurance benefits to the use of a certain type of health care, such as treatment in public hospitals, creates incentives against the efficient use of higher quality health care. When such constraint is lifted, but the public insurance scheme still determines a minimum level of coverage for each illness, first best efficiency is achieved. It turns out that placing constraints in the form of minimum levels of coverage for each illness is necessary for e±ciency. Removing such constraint decreases the relative price of high quality care for a subset of illnesses, and leads to too much high quality care used in equilibrium. This analysis suggests that the widespread practice of determining illness by illness coverage in public health insurance systems has an efficiency rationale, despite the administrative and informational difficulties that it entails

    Does higher owner participation increase conflicts over common land? An analysis of communal forests in Galicia (Spain)

    Get PDF
    Communal forests or Montes Vecinales en Mano ComĂșn (MVMC) are a type of private collective land in Galicia (northwest Spain) representing approximately one-third of its forest land. There has been a series of changes in MVMC ownership and management throughout the 20th century. Uncertainty about ownership, changes in population and the presence of the Forestry Administration has caused deficiencies in management and increased conflict. This paper analysed MVMC management in 1731 parishes in Galicia. The digital records of local and regional newspapers were used to compile a database of 2734 news reports related to MVMC issues. The results of hypothesis testing and spatial analysis showed that population, agricultural activity and land use affected management and conflict rates. This paper discusses how active management and conflict are complementary models, and how the presence or absence of one or the other is a determining factor in the situation of each parish. It concludes that it is necessary to implement management models and strategies to minimize conflict and increase active management for sustainable forest development in the region.We are grateful to the Galician Government, Xunta de Galicia, DirecciĂłn Xeral de InvestigaciĂłn, Desenvolvemento e InnovaciĂłn, Xunta de Galicia, for funding the project “A decision support system for montes veciñais en man comĂșn (DSSMVMC)” (07MRU035291PR)S

    Exploring the role of messenger effects and feedback frames in promoting uptake of energy-efficient technologies

    The persuasive potential for varying messenger types and feedback frames to increase pro-environmental choice was explored in a 2 (feedback frame: financial vs. environmental) × 5 (messenger type: neighbour, government, industry, utilities vs. control) factorial design experiment. Using the context of home heating choice, 493 non-student participants were given information on either the financial or environmental benefits of selecting an energy-efficient heat pump versus a standard boiler, as described by one of four messenger types (versus a no-messenger control). Likelihood of selecting the ‘green’ technology was assessed, as well as any carry-over effects on real-life behavioural intentions. Additionally, we assessed the messenger attributes that appeared to be most important in this context, in terms of whether sources that were perceived to be trustworthy, knowledgeable, or a combination of both dimensions, would hold greater sway over preference formation. Overall, no evidence was found for any impact of messenger type on either preference formation or behavioural intentions. However, message content (i.e. how information on the benefits of pro-environmental choice was framed), was found to have substantial impact on behaviour; with the financial versus environmental decision frame being significantly more likely to encourage uptake of the energy-efficient versus standard technology. We suggest that the level of processing required for the kinds of large-scale purchase decisions we consider here may explain the lack of any messenger effect on choice behaviour. Implications for the development of behaviour change interventions designed to promote consideration of energy-efficient technologies in this context are discussed

    An HEI-disaggregated input-output table for Wales

    Get PDF
    This paper describes how the education sector of the Welsh Input-Output tables is disaggregated to identify a separate sector for each of Wales’s twelve Higher Education Institutions (HEIs). The process draws on accounting and survey data to accurately determine the incomes and expenditures of each institution. In particular we emphasise determining the HEIs incomes source of origin to inform their treatment, as endogenous or exogenous, in subsequent analyses. The HEI-disaggregated Input-Output table provides a useful descriptive snapshot of the Welsh economy and the role of HEIs within it for a particular year, 2006. The table can be used to derive multipliers and conduct various impact studies of each institution or the sector as a whole. The table is furthermore useful to calibrate other multi-sectoral, HEI-disaggregated models of regional economies, including Social Accounting Matrix (SAM) and computable general equilibrium (CGE) models
