本文主要研究机构投资者非理性报价行为。在发行人(发行人与承销商的统称)理性假设下,建立模型并研究了机构给出不同价值信号时的发行价格设定与机构获配情况。文中分析发现当机构投资者拥有好的价值信息时,发行人的报价约束是有效的;当其拥有不好的价值信息时,报价约束完全不起作用,机构投资者会蓄意传达无价值或是好的信号,造成新股价格高于其价值。 相似文献

We investigate how investors should optimally choose to invest in a dynamically complete international market. We find closed-form solutions for the optimal investment strategy and for the wealth loss an investor suffers from not investing internationally. Theoretically, we show that the gain from international investment is due to the speculative investment only, and why it is important for an investor from a large economy to invest in a small economy. In a numerical example we compare the wealth losses investors from Denmark and the U.S. suffer due to home bias. 相似文献

This paper investigates whether financial deregulation causes economic growth through financial development. Financial development is measured by two channels: (1) changes in the allocation of credit across sectors, and (2) changes in savings and investment rates. We measure financial deregulation in China at the provincial level from 1981 to 1998. Our results suggest that financial reform causes economic growth in China. Further, its effect largely comes through the reallocation of credit across sectors, rather than changes in savings and investment rates. 相似文献

Based on time-use data from a 2013 primary household survey, this study examines the nature and extent of time-poverty experienced by men and women in peasant households in Mozambique. The main findings indicate that while women's labor allocation to economic activities is comparable to that of men, household chores and care work are almost entirely women's responsibility. The heavy burden of responsibilities leave women significantly time-poorer compared to men. Women's time-poverty worsens when the burden of simultaneous care work is taken into account. In addition, due to multitasking, the work tends to be more taxing. The examination of determinants of time-poverty shows that common measures of individual economic power, such as assets and education, do not necessarily affect the time-poverty faced by women. 相似文献

In this paper, we examine the effects of labor income taxation on growth in an overlapping generations model in which schooling and childcare play a role in the production of human capital. We compare such effects with those obtained in a model in which only schooling matters for skill formation. We show that the omission of childcare from the technology of skill formation can bias the results related to the impact of labor income taxation on growth. 相似文献

In humanitarian relief operations, vehicle routing and supply allocation decisions are critically important. Similar routing and allocation decisions are studied for commercial settings where efficiency, in terms of minimizing cost, is the primary objective. Humanitarian relief is complicated by the presence of multiple objectives beyond minimizing cost. Routing and allocation decisions should result in quick and sufficient distribution of relief supplies, with a focus on equitable service to all aid recipients. However, quantifying such goals can be challenging. In this paper, we define and formulate performance metrics in relief distribution. We focus on efficacy (i.e., the extent to which the goals of quick and sufficient distribution are met) and equity (i.e., the extent to which all recipients receive comparable service). We explore how efficiency, efficacy, and equity influence the structure of vehicle routes and the distribution of resources. We identify trends and routing principles for humanitarian relief based on the analytical properties of the resulting problems and a series of computational tests. 相似文献

In this paper, we study a pure exchange atomless economy with asymmetric information and having an ordered Banach space with an interior point in its positive cone as the commodity space. An extension of the main theorem in Vind (1972) to the private core without free disposal is established. As a particular case of this result, a solution to a problem mentioned in Pesce (2010) is derived. 相似文献

The optimal asset allocation of the main types of pension funds: a unified framework 总被引:1,自引:0,他引:1
Katarzyna Romaniuk 《The GENEVA Risk and Insurance Review》2007,32(2):113-128
The existing literature deals with the optimal investment strategy of defined benefit (DB) or defined contribution (DC) pension
plans. This article’s objective is to compare the optimal policies of different types of pension plans. This is done by first
defining an original framework, which is based on the distinction between the nature of the guarantee—which can be internal
or external—offered by or to a pension fund. This framework allows to establish links between optimization programs of DC,
DB and targeted money purchase schemes. The case of an internal guarantee appears as a standard portfolio insurer’s problem.
The second kind of guarantee, not analyzed in the literature yet with regard to the resulting optimal policy, is characterized
by the existence of an option in the final wealth definition. Four funds are present in the internal guarantee optimal allocation:
the speculative component, the preference independent guarantee- and contribution-hedge terms and the preference dependent
state variable-hedge fund. The external guarantee program, solved with an original method using the principles of standard
options theory, yields an optimal policy incorporating the delta of the option embodied in the final wealth definition. The
conclusion is that the resulting optimal portfolio policy becomes riskier.

This paper analyzes long-term comovements between hedge fund strategies and traditional asset classes using multivariate cointegration
methodology. Since cointegrated assets are tied together over the long run, a portfolio consisting of these assets will have
lower long-term volatility. Thus, if the presence of cointegration lowers uncertainty, risk-averse investors should prefer
assets that are cointegrated. Long-term (passive) investors can benefit from the knowledge of cointegrating relationships,
while the built-in error correction mechanism allows active asset managers to anticipate short-run price movements. The empirical
results indicate there is a long-run relationship between specific hedge fund strategies and traditional financial assets.
Thus, the benefits of different hedge fund strategies are much less than suggested by correlation analysis and portfolio optimization.
However, certain strategies combined with specific stock market segments offer portfolio managers adequate diversification
potential, especially in the framework of tactical asset allocation.
