ABSTRACT For Africa to develop and achieve sustainable development, African governments have to prioritise spending on public health. However, the current spending data shows that health spending is a continuing struggle for African countries. Many researchers have the view that African governments have to collect more tax to spend enough on public healthcare. The question here is what extent people are willing to pay more tax to increase spending on public healthcare? Employing a multilevel regression model on Afrobarometer survey data, this paper examined to what extent individual and country level factors influence people’s willingness to pay more tax to increase spending on public healthcare in 12 Southern African Development Community (SADC) member states. This study found that peoples’ trust in their government is an important determinant of willingness to pay more tax, while factors such as the country’s quality of democracy, economic condition, and current per capita health expenditure have no influence. 相似文献

In the debate on urban inequality, Sassen’s theory on social polarization and Wilson’s theory on spatial mismatch have received much attention. Where Sassen highlights the decline of the middle classes, Wilson focuses on the upgrading of urban labour markets. In this article we argue that both theories may be valid, but that they have to be put in a more extended theoretical framework. Of central importance are national institutional arrangements, membership of different ethnic groups and networks, and place–specific characteristics rooted in local socio–economic histories. As a first empirical illustration of our model, we use data on the labour markets of Amsterdam and Rotterdam and show that different forms of inequality can be found both in economic sectors and within ethnic groups. The model we present could be used both to reinterébatpret existing data and as an analytical framework for the analysis of different forms of urban inequality. Dans le d& sur l’inégalitéurbaine, la théorie de la polarisation sociale de Sassen et celle de la disparité spatiale de Wilson ont retenu l’attention. Alors que Sassen souligne le déclin des classes moyennes, Wilson s’attache à la revalorisation des marchés du travail urbains. Cet article soutient que, si ces deux théories sont admissibles, elles doivent étre placées dans un cadre théorique plus large. En effet, sont essentielles les dispositions institutionnelles nationales, l’adhésion de différents réseaux et groupes ethniques, et les spécificités du lieu enracinées dans les histoires socio–économiques locales. Comme première illustration empirique de notre modèle, nous utilisons des données relatives aux marchés du travail d’Amsterdam et de Rotterdam pour montrer qu’il y existe différentes formes d’inégalitéà la fois dans les secteurs économiques et les groupes ethniques. Le modèle présenté pourrait servir à réinterpréter les données existantes et fournir un cadre à l’analyse des diverses formes d’inégalité urbaine. 相似文献

William Jack 《Economics of Transition》2002,10(3):619-635
As part of the reforms of their systems for financing and delivering health care, many transition economies, particularly in central and eastern Europe, have adopted national insurance funds that are institutionally separate from ministries of health. Most of these countries have also grappled with the problem of restructuring the delivery system, especially the need to reduce hospital capacity. Although improving the performance of medical care providers through a shift from passive budgeting to explicitly incentive mechanisms is important, why this change in financial relations between the government and providers could not be implemented simply by reforming the role of health ministries is not obvious. This paper presents an explicit rationale for the separation of powers between the regulator (the ministry of health) and the financing body (the insurance fund), based on the inability of a single agency to commit to closing hospitals.

This article deals with the prediction problem in linear regression where the measurements are obtained using k different devices or collected from k different independent sources. For the case of k=2, a Graybill-Deal type combined estimtor for the regression parameters is shown to dominate the individual least squares
estimators under the covariance criterion. Two predictors ŷ
c and ŷ
p are proposed. ŷ
c is based on a combined estimator of the regression coefficient vector, and ŷ
p is obtained by combining the individual predictors from different models. Prediction mean square errors of both predictors
are derived. It is shown that the predictor ŷ
p is better than the individual predictors for k≥2 and the predictor ŷ
c is better than the individual predictors for k=2. Numerical comparison between ŷ
c and ŷ
p shows that the former is superior to the latter for the case k=2. 相似文献

The United States (US) exports more than US$6 billion in agricultural commodities to the European Union(EU) each year, but one issue carries the potential to diminish this trade: use of biotechnology in food production. The EU has adopted more stringent policies towards biotechnology than the US. Understanding differences in European and American policies towards genetically modified (GM) foods requires a greater understanding of consumers’ attitudes and preferences. This paper reports results from the first large‐scale, cross‐Atlantic study to analyse consumer demand for genetically modified food in a non‐hypothetical market environment. We strongly reject the frequent if convenient assumption in trade theory that consumer preferences are identical across countries: the median level of compensation demanded by English and French consumers to consume a GM food is found to be more than twice that in any of the US locations. Results have important implications for trade theory, which typically focuses on differences in specialization, comparative advantage and factor endowments across countries, and for on‐going trade disputes at the World Trade Organization. 相似文献

The Lowry Model Revisited: Incorporating a Multizonal Input-Output Model into an Urban Land Use Allocation Model 总被引:2,自引:0,他引:2
Myung-jin Jun & James E. Moore 《Review of urban and regional development studies : RURDS : journal of the Applied Regional Conference》2002,14(1):2-17
This paper formulates a new generation of Lowry-style models that combine a multizonal input-output model and an urban land use allocation model. Three different types of models are proposed: 1) an unconstrained model, 2) a primal of a linear programming approach that includes land supply constraints, and 3) a modified dual of the linear programming approach that allocates land based on additional conditions of economic efficiency. The modified dual formulation improves upon the limitations of Lowry models and their derivatives. First, the proposed model has sound theoretical underpinnings that incorporate the production theory of input-output models and the behavioral theory of optimization models. Second, the proposed model allocates land on the basis of economic efficiency by imposing a procedure that equalizes shadow prices. And third, the proposed model is an optimization model that fully accounts for the spatial and sectoral relationships of multiplier effects determining land use demand. 相似文献
