Abstract:
In this research the economic behaviour associated with the consumption of arsenic and fluoride contaminated groundwater and the use of arsenic and fluoride removal technologies in affected areas of Bangladesh and Mexico is analysed using a number of tools of economic analysis including analysis of household surveys and stated preference methods. In the first section, a health production function approach is used in order to estimate the economic costs of arsenicosis in rural households of Shahrasti, Bangladesh. Then, experimental data from rural communities in Bangladesh are used to assess the adoption of groundwater arsenic removal technologies in relation to risk and time preferences. The identification of such preferences is important because they determine people's propensity to use arsenic removal technologies and their ability to avoid arsenic related illnesses. Further, time inconsistent preferences can trigger self-control related problems like procrastination in the use of water filters. In the second section, a contingent valuation survey is used to elicit household willingness to pay responses for safe drinking water in Zacatecas, Mexico. The objective is to investigate households' willingness to pay for improved water quality through the installation of a new filtration system to remove fluoride and arsenic from groundwater. It was found that individuals' subjective perceptions of contamination might change their attitude towards the installation of water purification systems, thereby changing the effective price of potable groundwater that they are willing to pay. Different types of contamination (by arsenic and fluoride in this case) had differing effects on values. Value estimates also changed as the socioeconomic profiles of survey respondents changed. Further interdisciplinary research was conducted in order to achieve a better understanding of the problem of environmental contamination with arsenic, fluoride and heavy metals in Mexico.
