A statistical test is applied to explore the possibility that children can affect the efficiency with which parents consume. Parents may receive some economic benefits from children in the form of reverse integenerational transfers that occur because of a positive influence children have on family behavior. Results show that not only do children have an influence on parental consumption, but also that the influence is beneficial. In fact, not accounting for such a benefit could cause an underestimate in such measures as the rate of return to education or the benefits from such governmental programs as Head Start.  相似文献

Several textbooks, journal articles, and advertising practitioners indicate that the advertising for many products should be directed toward the heavy users of the product category. Other works suggest that advertising should be directed at current users of a brand to retain them or to users of competitive brands in an effort to attract them. The purpose of this article is to compare these directions for how advertising should be placed with data showing how advertising is being placed. The comparison is made using supermarket scanner panel data and household advertising exposure data. Examples are also provided to indicate the extent to which advertising could be targeted to heavy users of the product category and users of a brand, given the actual viewing and consumption patterns. Several implications for the placement of advertising are discussed.  相似文献

There are some major differences between working in Europe and working in Australia as a consultant in organization change. These differences relate more to theoretical positions and willingness to be open than to the use of specific techniques. In fact, there has rarely before in the behavioural sciences been such a universal adoption of like techniques. The same methods, exercises, interventions are used whether one is looking at the consultant in Britain, Europe, Asia or Australia. This in itself suggests some superficiality in that cross-cultural differences are assumed unimportant.  相似文献

Three different techniques for the estimation of a time-varying beta are investigated: a bivariate GARCH model, the Schwert and Seguin approach, and the Kalman filter method. These approaches are applied to a set of monthly Morgan Stanley country index data over the period 1970 to 1995 and their relative performances compared. In-sample forecast tests of the performance of each of these methods for generating conditional beta suggest that the GARCH-based estimates of risk generate the lowest forecast error although these are not necessarily significantly less than those generated by the other techniques considered.  相似文献
