Diversification gains in mean-variance efficiency derived from including real estate in financial asset portfolios are examined. Optimal financial and mixed-asset portfolios were generated by selecting from an investment universe including several distinct financial and real estate media. Deficiencies of previous studies were overcome by employing data with improved representativeness and comparability. The efficient mixed-asset portfolios dominated the efficient financial asset portfolios implying that purely financial asset diversification is inefficient. The optimal mixed-asset portfolio prescribed that approximately two-thirds of the investment wealth be allocated to real estate and one-third to the financial media. 相似文献

The concept of self-interest remains underdeveloped in sociology although central to economics. Recent methodological and social trends render sociological indifference to the concept untenable. The term has enjoyed historical predominance in the West since the sixteenth century. While it is seen in modern economics as a singular motivating force, Adam Smith regarded self-interest in economic action as necessarily moderated by sympathy. In addition to its problematic economic conceptualization self-interest has an experiential basis in unequal power relations. An alternative to the concept of self-interest is presented by Amartya Sen in his account of commitment; its inconsistencies, however, render Sen's statement unsatisfactory. Differences between present and future interests indicate that the distinction between self-interested and other-interested action is not sustainable. 相似文献

This article discusses a longitudinal study of firms selected for their expertise in environmental analysis. It is primarily designed to test two general propositions. The first, that environmental analysis is increasing in importance over time— both within and between firms; and the second, that environmental analysis is most viable as a separate, freestanding function within the organization. 相似文献

This article addresses issues involved in the treatment of fathers who do not have custody of their children. It reviews literature on demographic trends and discusses fathers' reactions to loss of child custody. Assessment and treatment guidelines are offered so that clinical practice may become more responsive to the needs of the population. Gender concerns, particularly as they relate to transference and countertransference, are also discussed. 相似文献
