We extend existing pricing models and develop a bivariate binomial option pricing technique that accommodates correlated state variables. This technique offers the ability to price American-style options, thereby accommodating early exercise, despite the existence of two correlated underlying state variables. Our technique is computationally efficient and can be further generalized for multiple-state variables, albeit with an accompanying rise in computational expense. 相似文献

Vitamin D is vital in all vertebrates because it allows them to absorb more calcium from their diets, contributing to stronger
skeletal systems, and taller statures. Using a source of 19th century US state prison records, this study contrasts the statures
of comparable African-Americans and whites by the primary sources of vitamin D production: time exposed to solar radiation,
skin pigmentation, and nativity. Greater insolation (sunlight) is documented here to be associated with taller black and white
statures, and a considerable share of the stature differential by socioeconomic status was related to insolation. 相似文献

The increasing use of transnational standard-setting bodies to address quality uncertainties and coordination issues across
the global economy raises questions about how these bodies establish and maintain their legitimacy and accountability outside
the sovereignty of democratic states. Based on a discussion of the legitimacy challenge posed by global governance, we provide
an overview of mechanisms by which such bodies can defend their legitimacy claims and examine the actual mechanisms used by
the International Accounting Standards Board (IASB). While the IASB staked its initial credibility on technical competence
and independence, it has increasingly emphasized due process norms in its claim for support. Our analysis evaluates the IASB
due process against the cultural benchmarks established by domestic standard-setters in the USA and UK and against a normative
model of procedural legitimacy. These comparisons help us to understand the modifications that were made in the hope of due
process adding legitimacy to accounting standard-setting beyond the state. They also reveal the broader political context
of competing legitimacy criteria that confronts transnational standard-setters. 相似文献

We examine the performance of pairs trading in the U.S. REIT market compared with that in the U.S. general stock market over the period 1987 to 2008. The results suggest that the REIT market provided superior profit opportunities for this strategy over common stocks after accounting for the effect of the bid‐ask bounce between 1993 and 2000. This was likely because of the unique characteristics of REITs, which permitted the selection of good pairs of close substitutes and the structural changes that occurred in 1993 in the REIT market. The superior trading profits in REITs disappear after 2000. 相似文献

A logistics model for emergency supply of critical items in the aftermath of a disaster 总被引:4,自引:0,他引:4
This paper proposes a logistics model for delivery of prioritized items in disaster relief operations. It considers multi-items, multi-vehicles, multi-periods, soft time windows, and a split delivery strategy scenario, and is formulated as a multi-objective integer programming model. To effectively solve this model we limit the number of available tours. Two heuristic approaches are introduced for this purpose. The first approach is based on a genetic algorithm, while the second approach is developed by decomposing the original problem. We compare these two approaches via a computational study. The multi-objective problem is converted to a single-objective problem by the weighted sum method. A case study is presented to illustrate the potential applicability of our model. Also, presented is a comparison of our model with that proposed in a recent paper by Balcik et al. [6]. The results show that our proposed model outperforms theirs in terms of delivering prioritized items over several time periods. 相似文献

The 2007–2009 financial crisis saw a vast expansion in deposit insurance guarantees around the world and yet our understanding of the design and consequences of deposit insurance schemes is in its infancy. We provide a new rationale for the provision of deposit insurance. In our model the banking sector exhibits both adverse selection and moral hazard, which implies that the social benefits of bank monitoring must for incentive reasons be shared between depositors and banks. Consequently, socially too few deposits are made in equilibrium. Deposit insurance – or, equivalently, bank recapitalization – corrects this market failure. We find that deposit insurance should be funded not by banks or depositors but out of general taxation. The optimal level of deposit insurance varies inversely with the quality of the banking system. Hence, when the soundness of the financial sector is uncertain, governments should consider supporting deposit insurance schemes and undertaking subsidized recapitalizations. 相似文献

We examine the investment appeal of small growth stocks by addressing: (1) the extent of mean reversion in small growth stocks; and (2) the set of financial variables that uniquely and strongly identify small growth stocks with the most investment appeal. We use 22 years of data derived from Forbes' annual list of best small growth companies. Our findings indicate that the market generally overreacts in the 36 months leading up to the month of Forbes' publication. Cumulative abnormal returns decline sharply after publication of Forbes list. We also examine whether Forbes' financial filters are justified or investors should expand the financial parameters to identify stocks with better investment appeal. Our findings suggest that three out of four Forbes financial filters to screen companies performed better in the post-publication period. Small stocks performed poorly in the post-publication period when analyzed on 13 additional financial variables. Specifically, sales growth rate, cash flow growth rate, 5-year compound EPS growth rate, and net income growth rate were more than halved for the average company in the 36 months after the publication of Forbes' list. These results suggest that financial filters Forbes used to generate its list may not capture the underlying performance of small stocks. In examining the two research questions, evidence is unsettling and to some extent contrary to that provided by prior research. 相似文献
