In the present paper, we give some general theorems on characterizations based on conditional expectations of the functions
of order statistics. In addition, we indicate special forms of the theorems for the familiar probability distributions. 相似文献

In Vietnam, girls are colloquially referred to as 'flying ducks' as they are regarded as a loss to the family upon marriage. Using the Vietnam Living Standards Surveys of 1992–1993 and 1997–1998, the method of Doiron and Riddell (1994) is applied to decompose the probability gap of being in school to explore gender differences in children's education and changes over time. The unexplained component is found to account for most of the observed gender probability gap in each period. Over time, however, the gap has narrowed. The explained component (namely, household income and children's involvement in housework or work activities) contributes to the narrowing gap. Cutting the indirect cost of education for girls (forgone contribution in work and housework) is crucial in ensuring girls have the same education opportunities as boys do. 相似文献

This paper develops a model of the European Community compound feed sector capable of explaining demand for feed ingredients, and the output demand and prices for compound feeds. The adopted framework rests upon the use of duality theory to represent the optimising production decisions of compound feed firms. In addition, an appropriate methodology is suggested to capture the rapid expansion in the consumption of compound feeds in the European Community and their adoption by livestock producers. The model is then applied to the French compound-feed sector using annual time-series data stretching over the period 1962–1980. 相似文献

In this paper we study the effect of local network externalities on the societal adoption of competing technologies. Three cases are examined: single non-sponsored technology, single sponsored technology, and two non-sponsored technologies. The efficiency and predictability of the technology adoption process for each case is investigated. We demonstrate non-predictability for single technology case and efficiency for the two technology case. We show the firm sponsoring a technology may choose a strategy that leads to the extinction of the technology. 相似文献
