Contingent valuation of ill health caused by pollution: testing for context and ordering effects

Contingent valuation is being increasingly used to value episodes of ill health caused by environmental pollution. In contrast to studies that have used contingent valuation to value other types of non-market goods, health episode valuation studies have tended to 1) value several ill health episodes or symptoms in the same survey, and 2) be vague in the survey instrument about the cause of the ill health, how it would be avoided or how the improvement would be paid for. The resulting values are then combined with exposure-response functions to generate economic estimates of health damages from pollution. This study tests whether episode valuation responses are sensitive to two of these design features. In a five-country study using split sample treatments, neither episode ordering nor mention of the cause of the ill health influenced stated willingness to pay to avoid specific ill health episodes.JEL Classification: C42, I12, Q51 Correspondence to: Richard ReadyThis research was supported by the European Unions Environment and Climate Research Programme: Theme 4 - Human Dimensions of Environmental Change (contract no.

The most popular tax in Europe? Lessons from the Irish plastic bags levy

There have been occasional ad hoc efforts to influence consumer behaviour by the imposition of product taxes that reflect external costs imposed by such products that are not initially included in their price. In the spirit of this idea, in 2002 Ireland introduced a 15 Euro cent tax on plastic shopping bags, previously provided free of charge to customers at points of sale. The effect of the tax on the use of plastic bags in retail outlets has been dramatic—a reduction in use in the order of 90%, and an associated gain in the form of reduced littering and negative landscape effects. Costs of administration have been very low, amounting to about 3% of revenues, because it was possible to integrate reporting and collection into existing Value Added Tax reporting systems. Response from the main stakeholders: the public and the retail industry, has been overwhelmingly positive. Central to this acceptance has been a policy of extensive consultation with these stakeholders. The fact that a product tax can influence consumer behaviour significantly will be of interest to many policymakers in this area. This paper analyses the plastic bag levy success story and provides insights and general guidelines for other jurisdictions planning similar proposals.

Benefit Transfer in Europe: How Reliable Are Transfers between Countries?

The benefits for specific health impacts related to air and water quality were measured in simultaneous contingent valuation surveys conducted in five different European countries. Consistent inter-country differences in willingness to pay to avoid ill health episodes could not be explained by measurable differences in individual characteristics. International transfer of unit values resulted in an average transfer error of 38%. Accounting for measurable differences among countries in health status, income and other demographic measures, either through ad hoc adjustments to the transferred values or through value function transfer, did not improve transfer performance.     

A ‘Natural Experiment’ Approach to Contingent Valuation of Private and Public UV Health Risk Reduction Strategies in Low and High Risk Countries

We present the results of a natural experiment to test how variations in exogenous risk levels affect resultant willingness to pay (WTP) for risk reduction. The case study presented considers WTP for reductions in the skin cancer risks associated with exposure to solar UV radiation. A common design contingent valuation survey is conducted in four countries, across which variation in geographical latitude and genetic mix mean that exogenous risks differ substantially. Survey respondents were presented with both a private and public good route for affecting risk reduction. In both cases, results confirm that once adjustment had been made for expected relationships with other covariates (such as income and risk averting behaviour), valuation responses for both goods conformed to expectations with the ordering of values across countries reflecting the ordering of scientifically established health risks. This suggests that links between values and objective health risks may be observed within such situations and provides a justification for continuing research into more natural representations of risk and risk reductions in order to yield consistent and robust measures of associated values.     

IFRS adoption in Spain and the United Kingdom: Effects on accounting numbers and relevance

This paper examines the quantitative impact of mandatory IFRS adoption on financial reporting issued by first-time adopters. It analyses whether relevance of financial information is higher under IFRS than the information provided in financial statements prepared under local GAAP when investors have to make decisions in the capital markets. Both studies compare results in Spain and in the United Kingdom, whose accounting systems have been traditionally considered in opposite groups. The results of the research reveal that the quantitative impact is significant in both countries and, against what we expected, it is higher in the United Kingdom. We also observe that IFRS have negative effect on the relevance of financial reporting in both countries, although this effect has only been significant in Spain.

Writing Across Contexts: Urban Informality and the State in Tallinn,Bafatá and Berlin

Urban research has long related informality to a lack of state capacity or a failure of institutions. This assumption not only fails to account for the heterogeneous institutional relations in which informality is embedded, but has also created a dividing line between states. Whereas some states are understood to manage urban development through functioning institutions, others, in this view, fail to regulate. To deconstruct such understandings, this article explores informal practices through a multi‐sited individualizing comparison between three case studies of water governance, parking regulation and dwelling regimes in Bafatá (Guinea‐Bissau), Tallinn (Estonia) and Berlin (Germany), respectively. Our approach to understanding informality starts from the negotiation and contestation of order between differently positioned actors in the continuous making of states. From this point of view, informality is inherent in the architecture of states––emerging through legal systems, embedded in negotiations between and within institutions, and based on conflicts between state regulations and prevailing norms. Tracing how order takes shape though negotiation, improvisation, co‐production and translation not only highlights how informality constitutes a modus operandi in the everyday workings of the state in all three cases, but also provides a way to talk across these cases, i.e. to bring them together in one frame of analysis and overcome their presumed incommensurability.     

Modelling economic circuit flows in a social accounting matrix framework. An application to Portugal

Aggregated Social Accounting Matrices (SAMs) will be built for the Portuguese economy in 1997, 1998 and 1999, based on the country's national accounts statistics. The SAMs will be shown as a working instrument for quantifying the flows in the economic circuit and for simulating the effects resulting from changes in such flows. The economic flows associated with the government subsectors will be emphasized, whilst accounting and fixed-price multipliers will be calculated to facilitate the study of the effects resulting from changes in the government's expenditure, which will also be subjected to a test on their veracity.
