ENERGY CONSERVATION AND LIFESTYLES: AN INTEGRATIVE APPROACH TO FAMILY DECISION MAKING*

The role of energy in supporting the family ecosystem is reviewed in terms of energy technology and family behaviour, information needs and family choice. The complexity of the family's dependence upon energy is highlighted as a major deterrent to effective decision making that would yield more energy-thrifty lifestyles. Some examples of the energy costs of different lifestyle choices are reviewed based upon research currently in progress. Finally some procedures are suggested for improving the supply of information to consumers and some family decision making strategies are recommended as more fruitful than others.     

A note on least squares estimation and the blue in a generalized linear regression model

In a generalized linear regression model, least squares and Gauss-Markov estimators differ, in general, if the variance-covariance matrix of the disturbances is singular. In the present note it is shown that, nevertheless, the conventional least squares procedure leads to a Gauss-Markov estimator if it is applied to a modified model which results from adding dummy constraints to the original model. These constraints reflect the effects of the singularity of the variance- convariance matrix. As a consequence, a Gauss-Markov estimate may always be obtained by standard least squares minimization, which offers considerable computational advantages.     

INTRAWEEK SEASONALITY IN THE FEDERAL FUNDS MARKET

This paper examines daily Federal funds interest rates for intraweek seasonality over the period 1966 through June 1982. Seasonals are identified using several techniques and are found to vary over time in both intensity and relative size. Furthermore, seasonality is not limited to a Wednesday effect. The seasonals are used to test the effectiveness of active reserve management based on seasonal rate forecasts. The results indicate that extraordinary risk-adjusted profits are not likely.
