| This study estimated monetary value of water quality improvement from 3rd class to 1st class in the Paldang reservoir using the contingent valuation method (CVM) to measure individuals' willingness to pay (WTP) of questionnaire respondents for improving the water quality of the Paldang reservoir and analyzed what factors influence their WTPs. This study also measured compliance costs of proposed regulations to the polluting sources. The estimated individual WTP was used to calculate the total WTP of the community affected, and then it was compared with the compliance costs of proposed regulations to the polluting sources. |

| Our primary concern in this paper is to determine to what extent small communities have difficulty meeting the new stricter 2001 standard for arsenic levels in their drinking water. To do this we survey water users in rural Minnesota communities that had arsenic levels in their water supply exceeding 10 g/L during 2001-2006. Our survey results show that after obtaining complete information concerning the arsenic levels in their drinking water consumers with relatively low levels of arsenic were willing to pay $8-9 annually, while those with high levels of arsenic are willing to pay $15-17 annually. We also found that consumer’s willingness to pay (WTP) didn’t vary by community size. Thus, we conclude that compared to compliance costs ($58-327 per capita... |

| The dynamic relationships among trade, income and the environment for developed and developing countries are examined using a cointegration analysis. Results suggest that trade and income growth tend to increase environmental quality in developed countries, whereas they have detrimental effects on environmental quality in most developing countries. It is also found that for developed countries, the causal relationship appears to run from trade and income to the environment ─ a change in trade and income growth causes a consequent change in environmental quality, and the opposite relationship holds for developing countries. |

| The contingent valuation method is applied to determine how much consumers would be willing to pay to reduce copper in their drinking water and what factors influence their willingness to pay (WTP). The annual mean WTP per household was estimated using survey data from nine counties in southwestern Minnesota where copper contamination is high. The annual mean WTP per household varied from a low range of $30.41 to $43.61 for Chippewa County to a high range of $39.79 to $57.06 for Nobles County. The aggregate WTP for all nine counties was estimated to range from $1.66 to $2.38 million. However, the estimated WTP may not be sufficient to pay the cost of providing improved water through public water systems for small communities in southwestern Minnesota. |
