This paper shows that different degrees of regulation affect electric utility firm's operating and financial strategies. The analysis also provides a potential approach for testing the Averch-Johnson effect using financial information which has been neglected until this time.

Based upon a generalized rates of return generating process, the correct functional forms of the capital asset pricing model (CAPM) for 85 individual mutual funds are statistically identified. The impacts of the functional form on the estimates of Jensen performance measure, beta coefficient and the unsystematic risk are also explored in detail.

This study focuses upon the annual number of births over the interval 1950-1974. Three important factors are isolated which are associated with births; these are, income, population size, and expenditures on birth control technology. Other variables inserted into the estimating equations were found to add little by way of forecasting improvements. Changes in contraceptive technology seem to be important in determining births. The increase in the power of the technology has made it feasible for households to more realistically examine children in the framework postulated by the Chicago School, Leibenstein, or Easterlin.
