Water quality in Lake Rotorua has been declining for at least the last 30 years as increased levels of nutrients have entered the lake. Despite significant effort and expenditure, the level of nutrients entering the lake still exceeds sustainable levels. A nutrient trading system would help the...

A nutrient trading system is one mechanism that is currently being considered to control and reduce nutrient loss into Lake Rotorua. However this may not be the best mechanism for controlling nutrient loss from all sources. A more comprehensive system improves efficiency and decreases market...

The Index of Drinking Water Adequacy (IDWA) was first introduced in the Asian Water and Development Outlook 2007, a report issued by the Asian Development Bank. The computation of the index (more recently christened IDWA-I) calls for data on five different parameters—resources, capacity,...

Industrial disposal of effluents on land and the subsequent pollution of groundwater and soil of surrounding farmlands – is a relatively new area of research. The environmental and socioeconomic aspects of industrial effluent irrigation have not been studied as extensively as domestic sewage...

We design a survey to provide quantitative evidence about household demand for qualitative aspects of tap water supply. We focus on two characteristics that are of importance for households: water hardness and aesthetic quality in terms of taste, smell and appearance. Our survey elicits...

Guided by a theoretical framework, we study how perceived relative income affects preferences for public goods. In a randomized survey experiment, we inform respondents from India of their official income rank and elicit preferences for air quality, including actual contributions to...

Researchers have long been interested in whether environmental regulations discourage investment, reduce labour demand, or alter patterns of international trade. But estimating those consequences of regulations requires devising a means of measuring their stringency empirically. While creating...

This paper examines with a case study of Beijing, China, the health benefits that could be reaped from urban air quality improvements. The study implements a household survey to collect information about the yearly medical expenditures and lost days of work, to estimates the total costs of...
