Are There Income Effects on Global Willingness to Pay for Biodiversity Conservation?

This paper is concerned with the empirical relationship between biodiversity conservation values and income. We use random effects panel models to examine the effects of income, and then GDP per capita, on willingness to pay for habitat and biodiversity conservation. In a meta-analysis, 145 Willingness To Pay estimates for biodiversity conservation where existence value plays a major role were collected from 46 contingent valuation studies across six continents. Other effects included in the meta-analysis were the study year; habitat type; continent; scope as presented to respondents; whether WTP bids were for preventing a deterioration or gaining an improvement in conservation, whether a specific species or specific habitat was protected; whether the questionnaire used a dichotomous choice or an open-ended format; distribution format; and the choice of payment vehicle. GDP per capita seemed to perform as well as an explanatory variable as respondent’s mean stated income, indicating that it is wealth in society as a whole which determines variations in WTP. Even if large variation, our main conclusion is, that the demand for biodiversity conservation rises with a nation’s wealth, but the income elasticity of willingness to pay is less than one.     

Using Choice Experiments to Value the Natura 2000 Nature Conservation Programs in Finland

This paper is concerned with the preferences of the Finnish households for a controversial nature conservation program – the European Union's Natura 2000 Network. Since the program was mainly based on biological considerations, it met strong public opinions from different interest groups in Finland. Using the choice experimental method, we attempt to estimate the values that the Finnish households would place on different preservation levels. It is found that the mean willingness to accept for a decrease in the nature preservation area is much greater than the mean willingness to pay for an increase by the same amount. Also, the marginal willingness to pay becomes zero after an initial increase in the natural preservation area, which is consistent with our earlier findings in a binary choice valuation study. Policy implications of these results are also discussed in relation to different decision criteria.     

Price Premiums for Eco-friendly Commodities: Are ‘Green’ Markets the Best Way to Protect Endangered Ecosystems?

‘Green’ markets represent a means through which public goods can be privately provided. A green product is an impure public good consisting of a private good (e.g., rain forest honey) bundled with a jointly produced public good (e.g., biodiversity protection). In the context of ecosystem protection, popular green commodities include eco-tourism excursions, coffee grown under forest canopies (‘shade-grown’), tagua nuts for buttons and ornaments, rainforest nuts and oils for cosmetic products, and rain forest honey. We examine the dynamic efficiency of eco-friendly price premiums in achieving ecosystem protection and rural welfare goals by contrasting the use of price premiums to the use of payments that are tied directly to ecosystem protection. We demonstrate analytically and empirically that direct payments are likely to be more efficient as a conservation policy instrument. Depending on the available funds, the direct payments may be better or worse than green price premiums in achieving rural welfare objectives. If direct payments are not feasible for social or political reasons, we demonstrate analytically and empirically that the price premium approach is likely to be more effective at achieving conservation and development objectives than the currently more popular policy of subsidizing capital acquisition in eco-friendly commercial activities.     

The Effect of Risk Characteristics on the Willingness to Pay for Mortality Risk Reductions from Electric Power Generation

The objective of this study is to estimate willingness to pay (WTP) for the reduction of mortality risks caused by fossil fuel (natural gas, coal and oil) versus nuclear electric power generation systems and to examine the influence of risk characteristics involved with electric power generation on WTP. A choice experiment was conducted to achieve these objectives. The attributes for nuclear risks in the experiment included the probability of disasters and the expected losses if a disaster occurs. We find evidence of (i) a baseline effect (where WTP is sensitive to hypothetical versus actual baseline expected mortality); (ii) a ‘labeling effect,’ where, surprisingly, the term ‘nuclear’ has no effect on WTP, but the term ‘fossil-fueled power generation’ results in lower WTP; and (iii) disaster aversion, meaning that people focus on the conditional loss from a nuclear disaster, not the probability. We also find that the WTP for reducing deaths from a nuclear disaster is about 60 times the WTP for routine reducing fossil-fuel generation-related deaths.     

‘Adopt a Hypothetical Pup’: A Count Data Approach to the Valuation of Wildlife

The willingness to pay (WTP) for a coyote conservation program is estimated using a novel payment-vehicle, based on how many ‚problem’ coyotes respondents would be willing to sponsor for a year. This hypothetical scenario mimics an increasingly popular type of actual market. Data from a phone survey conducted in Prince Edward Island are analyzed using count data models that consider different processes explaining zero responses and the level of positive responses. This is particularly important in the case of coyotes, often regarded as an economic bad. Estimates of WTP per coyote per year around $18–$22 and annual WTP per contributor of about $46–$57 are obtained.      

Threshold effects and incentives for the conservation of biodiversity

Biological diversity is a central component of the stock of natural capital on which all economic development is based. Other things being equal, loss of biologically diversity implies loss of development potential, and its conservation through sustainable use or outright protection implies the protection of that potential. One characteristics of biodiversity loss of especial importance is that biodiversity loss, more than any other current environmental problem, is associated with ecological threshold effects. The paper explores the implication of this characteristics for the properties of a biodiversity conservation strategy.     

Health effects on children’s willingness to compete

The formation of human capital is important for a society’s welfare and economic success. Recent literature shows that child health can provide an important explanation for disparities in children’s human capital development across different socio-economic groups. While this literature focuses on cognitive skills as determinants of human capital, it neglects non-cognitive skills. We analyze data from economic experiments with preschoolers and their mothers to investigate whether child health can explain developmental gaps in children’s non-cognitive skills. Our measure for children’s non-cognitive skills is their willingness to compete with others. Our findings suggest that health problems are negatively related to children’s willingness to compete and that the effect of health on competitiveness differs with socio-economic background. Health has a strongly negative effect in our sub-sample with low socio-economic background, whereas there is no effect in our sub-sample with high socio-economic background.     

Competition policy: ten lessons learnt from the financial crisis

The financial crisis brought great challenges also for competition policy. The aim of this paper is to summarize the most important insights for competition policy that could be derived from the turbulent period 2008–2010. The financial crisis is seen as project that demanded sound management from competition policy and enforcement. The insights will be presented in the instructive form of ‘lessons learnt’ which represents a common approved project management technique. We come to the result that the financial crisis is not the result of ‘too much competition’, but of regulatory failure and that the main answers to the financial crisis have to come from ‘smart regulation’. The relaxation of competition policy would be the wrong policy response in troubled times since competition policy can play an important role in bringing the crisis economy back on track. In contrast to banking we see no economic rationale for rescue packages for other economic sectors by referring to systemic risk. The renaissance of industrial policy is viewed with great skepticism since empirical evidence shows that the effort of picking ‘winners’ all too often results in saving ‘losers’.     

Keynes and Wagner on government expenditures and economic development: the case of a developing economy

This paper investigates the Keynesian view and the Wagner’s Law on the role of public expenditure on economic growth for Malaysia (1970–2004). The empirical results using the Auto-Regression Distributed Lag (ARDL) model and the ‘bounds test’ (Pesaran et al. in J Appl Econ 16:289–326, 2001) showed evidence of a long run relationship between total expenditures (including expenditures on defense, education, development and agriculture) and Gross National Product. The results also show that with the structural break in 1998, the long run causality is bi-directional for GNP and expenditures on administration and health, supporting both Keynes view and Wagner’s Law. For all other expenditure categories the long run causality runs from GNP to the expenditures, which supports Wagner’s Law. An erratum to this article can be found at
