| In this paper an approach that can be used to determine the distribution of a productivity gain on an industry is detailed. In particular, the model developed in this paper extends earlier evaluations by emphasising the crucial role of substitution between inputs across different participants in the supply chain. Crucial to any analysis of an industry are the estimates of the elasticity's of derived demand at each stage and how it changes, as the product is further refined. The wool industry is used to illustrate the effects of an innovation across sectors. |

| The view that the price of water is too low and that water does not flow to its highest value end use, have led many analysts to conclude that a market for water, in which price can adjust to accommodate changes in the supply and demand for the product, is essential. However, this solution assumes that the market could approach something close to perfect competition, purely by making minor changes within the existing regime of property rights. In this paper it is argued that problems evident in this market stem from a multitude of market failures and characteristics that are particular to it. To understand this case more fully it is necessary to come to terms with the theoretical formulations of the market for water and the practical difficulties... |

| The current study uses contingent valuation technique to estimate the value of clean water in river Musi in Hyderabad, India. The main source of pollution of the river is untreated domestic and industrial wastewater from the urban area of Hyderabad. Therefore, people’s Willingness To Pay [WTP] for the treatment of their wastewater to different quality levels (Level C, B & A) is estimated using a payment card method. Four variables were considered to influence the willingness to pay - number of years the household lived in Hyderabad; individual perceived importance of controlling water pollution; household income levels and proximity to the river. The results of the logistic regression confirmed that the variables - perceived importance of the... |
