Perception of epistemic authorities by children and adolescents

The study investigated children's and adolescents' perceptions of epistemic authorities in various knowledge domains. Children and adolescents from 4th, 8th, and 12th grades were asked to evaluate their father, mother, teacher, and friends as epistemic authorities in nine areas of knowledge content. In general, the results indicated that the perception of parents as epistemic authorities decreases with age. Nevertheless, children and adolescents continue to consider one or both parents to be the most important epistemic authorities. The perception of friends as epistemic authority increased relative to other sources in the social domains of knowledge. The perception of teachers as epistemic authority decreases with age, but in the formal knowledge domain it remains relatively stable.Received Ph.D. in clinical psychology from the Hebrew University in Jerusalem.

Freedom and growth: Do constitutions matter?

This paper uses an augmented Solow model, with cross section data, to measure the effect on per-capita income of a) the entrenchment of various rights in a country's constitution and b) the level of economic freedom in a country, broadly construed. The results suggest that entrenchment,per se, of any single right seldom has a significant general economic effect, while the effect of economic freedom is significant and substantial. The paper then considers whether such evidence could support the proposition that “constitutions do not matter.” While it concludes otherwise, it does caution against incurring excessive negotiation costs to obtain entrenchment of a comprehensive “wish list” of rights.     

Explaining differences in productive efficiency: An application to Belgian municipalities

The purpose of this paper is to measure and explain variations in productive efficiency of municipal governments in Belgium. Technical efficiency is evaluated using a non-parametric method based on the Free Disposal Hull (FDH) reference technology. We first calculate input, output, and graph Farrell efficiency measures for a cross-section of all 589 Belgian municipalities. In a second stage of the analysis we explain the calculated differences in efficiency in terms of variables related to the structural characteristics of municipalities and to the institutional environment.     

Medicaid's Role in Moves Toward Universal Health Care

This paper considers the problems currently facing the Medical Assistance (Medicaid) program in light of the major problems confronting the American health care system. Actual and proposed Medicaid reforms are reviewed, their merits noted and their shortcomings detailed. It is argued that substantial Medicaid reform can take place only in the context of radical reform of the entire U.S. health care system. Similarly, Medicaid should be incorporated into any plan aimed at providing universal health care coverage.     

Public choice and the EPA: Empirical evidence on carbon emissions violations

This study provides evidence of public choice determinants of the penalties assessed by the Environmental Protection Agency for carbon emissions violations. Following the work of Stigler (1971), Peltzman (1976), Tollison (1982), and Tullock (1989), this study points out that powerful business interest groups are able to use their political influence to shape EPA environmental policy for urban areas. The statistical estimates presented here suggest that business groups have limited power (through lobbying activity) in affecting the probability of the occurrence of an EPA citation for carbon emissions violations, while they may have considerable power in influencing thedegree of an EPA citation for carbon emissions standards, once a citation occurs.     

Variation in central bank independence across countries: Some provisional empirical evidence

In this paper seven hypotheses to explain variation in central bank independence across countries are tested. The predictions based upon the theory that delegation of authority by politicians to the central bank is used as a commitment device are not supported: central bank independence is not higher the larger the employment motivated inflationary bias, the higher political instability or the larger the government debt. Central bank independence is positively related to historical inflation experience and negatively with political instability. We do only find limited support for the view that countries with a universal banking system and countries whose central banks do not regulate financial institutions have more independent central banks.     

Developing economics expertise for the evaluation of primary health care

Given that government budgets are increasingly stretched in the face of competing demands, there is a pressing need for evidence on the costs and benefits of public sector investments. Nowhere is this need greater than in the health field, where the benefits of programmes are typically difficult to measure. Within the health sector a key area of interest is primary health care, which is generally regarded as a central function and the most important means by which the health of the population can be improved. This paper reports the results of a recent survey of Commonwealth countries which sought to establish the extent of economic evaluation of PHC programmes, the impact on decision-making and the level of health economics expertise available in Third World countries. Based on the results of the survey, suggestions are made for improving the commissioning and conduct of economic evaluations, for interpreting and implementing evaluation results, and for developing government expertise in economic evaluation.     

POLICY AS A MOVING TARGET: A CALL FOR CONCEPTUAL REALISM

Since the early 1970s, policy scholars have paid great attention to issues of policy implementation, treating it as the "missing link" between policy formulation and results. Most often, policy problems have been seen as static phenomena that can be corrected by carefully specified programs. This paper, drawing upon examples from Swedish energy policy, argues that this is not the case, that political and social conditions are so prone to change that implementation must be a dynamic process if it is to be effective. This has distinct conceptual and practical implications for the study and design of policy implementation.
