| Why would anyone want lower quality drinking water? The Safe Drinking Water Act allows an "affordability, variance technology, small system variance exemption" to the drinking water standards based on a supply side argument. It assumes small drinking water systems have significant diseconomies of scale in meeting the maximum contaminant levels. We can test this assumption by examining the cost of compliance technologies by system size developed by the Environmental Protection Agency to meet the mcl for arsenic. The data show that the least costly arsenic reduction technology to meet the current mcl of 10 parts per billion (ppb) is modify coagulation/filtration. This technology is also six to seven times more expensive to implement for very small systems... |

| Tornquist input quantity indices were used to derive total and partial factor productivity measures for U.S. cotton across time, region, and scale. Total factor productivity for U.S. cotton increased .2 percent per year between 1974 and 1982. Partial productivity measures revealed that yield growth was about .6 percent and input use grew about .4 percent per year. Cotton enterprises in Alabama and Mississippi gained and those in the Texas High Plains lost competitive advantage relative to California. In 1982, very large (1750-5900 acres) and large (950-1749 acres) cotton enterprises were 2 percent more productive than medium-size enterprises (570-949 acres). |
