This paper explores bond immunization for additive term structure models. This class of term structures contains many models that are commonly used in the duration and immunization literature. We establish the necessary and sufficient conditions for immunization and prove the existence of a bond portfolio that satisfies the immunization condition. Based upon the immunization condition, we develop a general definition of duration that applies to any additives term structure model. 相似文献

Fund Advisor Compensation in Closed-End Funds 总被引:2,自引:0,他引:2
This paper examines the relation between the premium on closed-end funds and organizational features of the funds and advisors, including the compensation scheme of the investment advisor. We find that the fund premium is larger when: (a) the advisor's compensation is more sensitive to fund performance; (b) the assets managed by the advisor are concentrated in the fund in question; (c) the advisor manages other funds with low compensation sensitivity to performance and with low concentration of assets managed by the advisor; and (d) the advisor's compensation contract evaluates performance relative to a benchmark. 相似文献

The Demand for Hedging and the Value of Hedging Opportunities 总被引:1,自引:0,他引:1
Darren L. Frechette 《American journal of agricultural economics》2000,82(4):897-907
Hedging strategies typically assume that hedging is costless and that only one futures market exists. When these assumptions are dropped, the demand for hedging is shown to depend on basis risk, price risk, and the hedger's risk preference. The marginal and incremental value of hedging opportunities are computed for the general cases of one and two markets and applied to the specific case of Pennsylvania dairy input hedging. 相似文献

Summary At a time when, despite Affirmative Action Goals, we still have great difficulty in making employers accountable before the
law for overt acts of discrimination, it is well to recall the doughty struggle of the state’s Blacks versus employers. At
a time when health services for inner-city residents continue to be worse than provisions for other citizens, it is well to
remember that even in the last century “the conditions of sickness and mortality” were “not the same for the white and for
the colored races,” and destitution among Blacks in New York City accounted for some 37 percent of the illnesses among Blacks
in that area. At a time when realtors and boards of education still effectively put up barriers to ordinary social relations
between whites and Blacks it is well to remember that even after the passage of the Fourteenth Amendment Blacks were powerless
to cause any major breach in public constraints to their mobility. Blacks have been powerless for a long time to make legislated
freedom subserve their economic and social goals, and this is an important reminder to those who would reapply the methods
of the past in attempts to fulfill today the normal economic expectations of citizens of the Republic. 相似文献

Electronic commerce has the potential to reduce transaction costs drastically. It is the most dynamic sector of the world economy. Governments should restrain themselves from extending taxes to electronic commerce or they will reduce the gains from innovation. 相似文献
