Estimation of Substitution Possibilities between Water and Other Production Inputs

摘要: The traditional approach to measuring the demand for water by industries relies upon fixed water-use coefficients. Water supply planners base decisions about system expansion partly coefficients applied projected levels of industrial growth. Among restrictive assumptions implied this is that producers are generally unresponsive relative price compared with other factors. Earlier studies focused on industry-by-industry assessments present and potential use technologies possibilities substituting productive inputs water. Most these economic engineering in form.

Because they used linear programming techniques, their results must be interpreted cautiously. flexible functional forms which have become
