Environmental taxes with heterogeneous consumers: an application to energy consumption in France

This paper constructs a model with four groups of households who have preferences over labor supply, consumption of polluting (energy related) and non-polluting (non-energy) goods, and emissions. It quantifies the model for the French economy and computes its optimal tax equilibria under nine second-best tax regimes. We find that the redistributive role of environmental taxes requires the polluting goods to be taxed at a rate much below their marginal social damage. These goods may even require an outright subsidy if the society values equality ‘a lot’. Secondly, if environmental taxes that have an exclusively externality-correcting role, they benefit all types—although the gains are rather modest. The gains and losses become more substantial when environmental taxes have a redistributive role as well. Third, setting the environmental tax at its Pigouvian level, rather than its optimal externality-correcting-cum-redistributive level, benefits the high-income group at the expense of the low-income groups. Fourth, nonlinear taxation of polluting goods, and nonlinear commodity taxation in general, is a powerful redistributive mechanism. Fifth, introducing environmental taxes in the current French tax system, with its suboptimal income taxes, results in substantial welfare gains for the highest income group and a sizable loss for the least well-off persons.     

Measuring Employment Security in Europe Using Surveys of Employers

Using results from surveys in which employers were questioned about their freedom to shed staff, we develop a measure of employment security in Europe. We seek to identify which institutional factors are correlated with the responses of employers and find that they appear to reflect the strength of legal restrictions and trade unions and the prevalence of atypical employment. Our results are used to compile an index of employment security that has both a temporal and a cross‐country dimension.     

passive drinking

The threat to health from passive smoking is now well understood. Andrew Wilson, a freelance healthcare journalist, reveals the alarming results of recent research into ‘passive drinking’. Without wishing to cause alarm Economic Affairs wonders how seriously we should treat these new findings?     

Management and the Professions: How Cracked is That Glass Ceiling?

All prestigious or highly-paid occupations in Britain are dominated by men: this is as true of the public sector as it is of industry. This article examines the evidence for discrimination in the public sector. It deals with both the situation at work and the one at home. It looks at various explanations as to why this is the case, as well as the evidence on how men and women deal with the inequality. The author concludes that there are good reasons why men and women do not see or confront the issues discussed in her article. Unless men and women wake up to the fact that we live in an unequal society and wish to see the glass ceiling well and truly broken, little is likely to change.     

Protection of diffuse interests in the EEC and the perspective of “progressively establishing” an internal market

Present Community action and law is characterised by a conflict between market integration, protection of diffuse interests, and the rule-of-law principle. Community law first concentrated on negative integration which created and protected traders' freedom of market access and workers' freedom of circulation. By Court practice, these freedoms were developed into a basic right of EEC citizens to move freely within the EEC and to satisfy their demands wherever they wanted. Positive integration tried to establish common protective standards in matters relating to the environment, consumer protection, health care, and equal rights. The Single Act, ratified in 1987, amended the EEC Treaty by the objective of completing the internal market by the end of 1992. These provisions can only to a limited extent be said to have a direct effect. Positive integration has been reinforced by provisions on environmental and health policy. In his concluding remarks, the author insists on the need for an overall expansion of protective standards within the EEC in spite of tendencies towards a mere free trade approach.

Zusammenfassung Die gegenwärtigen Aktivitäten der Gemeinschaft sowie das europäische Wirtschaftsrecht sind von einer komplexen Spannungslage zwischen Marktintegration, Schutz diffuser Interessen (Umweltschutz, Verbraucherschutz usw.) und rechtsstaatlich-demokratischen Anforderungen beherrscht. Zunächst konzentrierte sich das Gemeinschaftsrecht auf Maßnahmen der sog. Negativintegration, um dem Marktbürger Zugang zu dem Gemeinsamen Markt und Arbeitnehmern Zirkulationsfreiheit zu gewährleisten. Die Praxis des Gerichtshofes der EG hat diese Marktfreiheiten zu grundrechtsähnlichen Gewährleistungen aller Bürger i.S. einer Entscheidungs- und Aufenthaltsfreiheit ausgebaut. Die Positivintegration versuchte, gemeinsame Schutzstandards in den Bereichen Gleichbehandlung, Umwelt, Gesundheit und Verbraucherschutz durch sekundäres Gemeinschaftsrecht zu schaffen. Die 1987 ratifizierte Einheitliche Europäische Akte hat das Ziel der Gemeinschaft festgeschrieben, bis Ende 1992 den Binnenmarkt als Raum ohne Binnengrenzen zu verwirklichen.Die unmittelbare Wirkung dieser Vorschriften bleibt allerdings fraglich. Die Positivintegration ist durch Kompetenzen im Bereich Umwelt- und Gesundheitsschutz abgesichert worden. In einer Schlußbetrachtung wird auf die Notwendigkeit EG-einheitlicher Schutzstandards ungeachtet des Vorherrschens von Freihandelsvorstellungen hingewiesen.

Preventing HIV in injection drug users: exploring the tradeoffs between interventions

Injection drug users (IDUs) transmit the human immunodeficiency virus (HIV) via both needle sharing and sex. Available interventions for this population have varying costs and effectiveness and focus on different risk behaviors. In this analysis, we look at two interventions. One is inexpensive, broad-based and provides modest risk reductions (street outreach (SO)); the other is narrowly focused, expensive and relatively effective (methadone maintenance). This analysis explores the effects of population risk behavior, intervention effectiveness, intervention costs, and decision constraints when allocating funds between these two interventions to maximize effectiveness. We develop a model of the spread of HIV, dividing IDUs into susceptibles (uninfected) and infectives, and separately portraying sex and injection risk. We simulate the epidemic in New York City for time periods from the mid-1980s to the early 1990s, and incorporate the behavioral effects of two interventions performed singly or in combination to find the allocation that maximizes the number of infections averted in the IDUs and their noninjecting sex partners, assuming interventions have increasing marginal costs. We find that the optimal allocation nearly always involves spending the maximum allowable amount on SO. This result is largely insensitive to variations in risk parameters, intervention efficacy, or cost. The model's structure, however, makes clear that many factors contribute to this insensitivity, namely the scope of the interventions, the dual drug/sex nature of HIV risk in the population, the asymmetry of sexual risk for men and women, and the potential benefits to nonIDUs.
