Harmful algal bIoom species are the cause of important damages to marine living resources and human beings. These marine species are primarily introduced in North-European waters through ballast water, i.e. water trans-ported across the oceans so as to keep a vessel in balance. Port authorities...

We estimate willingness to pay (WTP) for better quality of tap water on a unique cross-section sample from 10 OECD countries. On the pooled sample, households are willing to pay 7.5% of the median annual water bill to improve the tap water quality. The highest relative WTP for better tap water...

The most popular survey method used in contingent valuations asks "open-ended" dichotomous choice questions. This method generates grouped or interval-censored data on respondents' willingness to pay. This paper specifies the willingness to pay distribution using the proportional hazard...

Spike models allow for a non-zero probability of zero willingness-to-pay in referendum-style contingent valuation experiments. They include many of the often used models as special cases and allow various analyses that are not possible in standard applications. This paper discusses the economic...

The usual decomposition of effects in corner solution models into extensive and intensive margins is generally incompatible with a causal interpretation. This paper proposes a decomposition based on the joint distribution of potential outcomes which is meaningful in a causal sense. The...

We estimate willingness to pay (WTP) for better quality of tap water on a unique cross-section sample from 10 OECD countries. On the pooled sample, households are willing to pay 7.5% of the median annual water bill to improve the tap water quality. The highest relative WTP for better tap water...

Few studies have explored, to date, the issue of the monetary valuation of non-fatal injuries caused by road traffic accidents. The present paper arises interest in this question and aims to estimate, by means of the contingent valuation, the willingness to pay (WTP) of French households to...

Cassava peeling machines are available but are inaccessible and prohibitively expensive, especially for small-scale processors to acquire. This paper examines the perception and willingness of smallholder cassava processors to pay for cassava peeling machine services using data from 300 cassava...

In order to complete cost benefit analyses of acidification policies, an attempt was made to monetarize the benefits of increased nature quality. So far, several benefits of acidification abatement, such as reduced health risks, had been determined, but the benefits of increased nature quality...
