Iva Zvěřinová and Milan Ščasný, researchers from the Department of Environmental Economics and Sociology of the Charles University Environment Centre, worked on a large scale OECD project Surveys on Willingness-to-Pay to Avoid Negative Chemicals-Related Health Impacts (SWACHE). They are authors of a working paper named "Valuing a reduction in the risk of very low birth weight". The project goal is to establish internationally comparable values for individuals’ willingness-to-pay to avoid negative health effects due to chemicals exposure.
To derive willingness-to-pay values, surveys of a large number of citizens of 22 countries have been conducted. The survey results show that people are willing to pay a significant amount of money to reduce their risk of developing various negative health effects
