FAMILY LIFESTYLE AND ENERGY CONSUMPTION: AN ENERGY ADAPTATION MODEL*

The premise of the paper is that family energy consumption is a consequence of family lifestyle. To facilitate the development of policies that allow families to make satisfactory lifestyle choices as energy resources decline, we explore in detail the relationship between family lifestyle and energy consumption. A model is developed to illustrate the decision making processes that link individual and family behaviour patterns with energy consumption. A series of propositions is derived from the model that relates family values, family effectiveness and family decision making to energy prices, energy conservation adoption, attitude formation and family lifestyle changes. The model can be used by public and private decision makers to identify research and consumer information programs that will facilitate adoption of more energy efficient lifestyles.     

Nonlinearities in Exchange-Rate Dynamics: Evidence from Five Currencies, 1973–94

Although exchange rates appear to follow a random walk when tested against linear alternatives, the null hypothesis of a random walk is rejected against a cubic alternative which embodies the intuition that the rate of mean-reversion increases with distance from equilibrium. A possible theoretical foundation for such a model is suggested. The model is tested on bilateral real exchange rates between four major currencies, and on the real effective exchange rate of these four plus the Australian dollar. The cubic model consistently outperforms its linear counterpart and the results imply that real exchange rates are in fact stationary.     

Emerging Evidence of Early Indian Accounting

The paper examines the extant late-eighteenth-century accounting record books of Kantababu, a Bengali property owner and silk trader. These annual records, in part destroyed by white ants and other insects, do not make up a complete set for more than any two Bengali solar years. Yet from the available evidence it is possible to make a case that some elements of the accounting systems used by Kantababu and his clerks have similarities to medieval and later European methods and to eleventh-century methods used by Cairo merchants as evidenced by documents stored in the Genizah of the Old Cairo synagogue.
