OPTIONS AND EFFICIENCY IN MULTIDATE SECURITY MARKETS 总被引:1,自引:0,他引:1
This paper extends the work of Ross (1976; Q. J. Econ. (90)1, 75–89) to multidate security markets. First, we show that if a primitive security separates states at the terminal date, then there exist multiperiod European options on that security generating dynamically complete markets. Second, we show that if a primitive security conditionally separates states at the terminal date, then there exist multiperiod European options on that security generating generically dynamically complete markets provided that certain conditions hold. Third, we show that there are economies for which the minimum number of multiperiod European options on a primitive security generating generically dynamically complete markets is relatively large. Finally, we show that in these economies, a relatively small number of multiperiod European options on possibly different portfolio strategies of primitive securities generates generically dynamically complete markets. 相似文献

Edmond Malinvaud 《Revue internationale de statistique》1997,65(1):97-109
Thinking about future needs and about what can reasonably be expected as feasible in the next century, how should producers of statistics direct their activity? Increasing complexity and diversity of needs leads us to recognize that, between producers and users of statistics, a mediating role is more and more often played by analysts and research workers who are requesting above all good data bases. Concerning infrastructures for statistics on productive systems, coordination between accountants and statisticians will be crucial, as well as adaptation of the constraints which, because of excessive worry about confidentiality, could prevent establishment or use of data bases. In an increasingly competitive world, where private firms will sell analyses and informations, particularly on very large enterprises, the public statistical service will remain essential in all respects. Intangible investments, innovations and many aspects of the internal organization of firms will create formidable challenges. Information on employment and labour markets has been much developed during the past decades; but on a few specific and difficult issues progress is still needed: lifecyles in the working-age population, acquisition of knowledge and skills in formal education and on the job, matching labour supplies and demands, and so on. Particular attention will have to be given to the lower levels of cultural and professional skills. 相似文献

During and after the Asian crisis, institutional investors and pension funds in Asian financial markets have been confronted with a number of difficulties effecting their performance and the way they carry out their role within the national pension system. We analyze these problems by comparing the actual investment policy of an institutional investor with an optimal investment strategy derived from the insights of modern portfolio theory. We also analyze whether the organizational set‐up of a pension fund allows it to adequately perform its role within the pension system. As an example, we examine the operations of the Thai Government Pension Fund (GPF). We find that allowing international investments and reducing restrictions on equity investments while lowering the implicit requirements for investments in government debt would allow the GPF to further diversify its investment risk and to increase its risk‐adjusted return. We also show that some changes in the governance structure of the GPF would lower the occurrence of conflicts of interest for the management and increase the efficiency of the GPF operations. 相似文献

To date, the discussion of the Lev and Thiagarajan 1993 fundamentals in the prior literature has been exclusively in the context of the stock market. Our study is the first to examine the value‐relevance of these fundamentals for default risk. By focusing on the market for new bond issues, we examine the value‐relevance of the fundamental score using expected rather than realized returns. Also, by focusing on the bond market we provide a different perspective than that brought by prior studies relying solely on stock prices. We find the fundamentals to be priced in the market for new bond issues as indicators of expected future earnings and to be value‐relevant in enabling the market to discern differences in bond credit quality over and above the published bond ratings. 相似文献

Reductions in international interest rates are a major cause of capital flows to emerging economies. Increases in domestic interest rates are a frequent policy response to the resulting price increases. This is often unsuccessful. The paper suggests a theoretical explanation based on distinctive features of emerging financial markets, including imperfect asset substitutability and imperfect capital mobility for some sectors of the economy. It concludes that the appropriate policy response to capital inflows may be lower interest rates. 相似文献
