Clearinghouses support financial trades by keeping records of transactions and by providing liquidity through short-term credit that participants clear periodically. We study efficient clearing arrangements for exchanges, where traders must clear with a clearinghouse, and for over-the-counter (OTC) markets, where traders can clear bilaterally. When clearing is costly, it can be efficient to subsidize OTC clearing by charging a higher clearing price for transactions conducted on exchanges. The clearinghouse then operates across both markets. Since clearinghouses offer credit, intertemporal incentives are needed to ensure settlement. When liquidity costs increase, concerns about default lead to a tightening of liquidity provision.  相似文献

Since the nineteenth century, Tamil Brahmans have been very well represented in the educated professions, especially law and administration, medicine, engineering and nowadays, information technology. This is partly a continuation of the Brahmans' role as literate service people, owing to their traditions of education, learning and literacy, but the range of professions shows that any direct continuity is more apparent than real. Genealogical data are particularly used as evidence about changing patterns of employment, education and migration. Caste traditionalism was not a determining constraint, for Tamil Brahmans were predominant in medicine and engineering as well as law and administration in the colonial period, even though medicine is ritually polluting and engineering resembles low-status artisans' work. Crucially though, as modern, English-language, credential-based professions that are wellpaid and prestigious, law, medicine and engineering were and are all deemed eminently suitable for Tamil Brahmans, who typically regard their professional success as a sign of their caste superiority in the modern world. In reality, though, it is mainly a product of how their old social and cultural capital and their economic capital in land were transformed as they seized new educational and employment opportunities by flexibly deploying their traditional, inherited skills and advantages.  相似文献

Most research on employee stock plan participation investigates the effects of such forms of ownership on employee attitudes, leaving our understanding of the individual differences that contribute to employee ownership largely unknown. Drawing from the consumer behavior literature, our study explores the effect of organization-based identity on the decision to participate in an employee stock purchase plan. The study was conducted in a newly public firm where we examine the effect of organization-based identity on the purchase decision in two time periods. The first point in time was the initial public offering (IPO), when the employee has little information on how the firm's stock will perform in the market. The second point in time was the first quarter following the IPO, when employees have market data to help them with decision-making. Results indicate that, as predicted, organization-based identity is associated with participation in an employee stock purchase plan, at both points in time, above and beyond the influence of several economic and psychological predictors reported in prior studies.  相似文献

This paper examines competition between exchange traded funds (ETFs) that hold nearly identical portfolios of securities. We provide evidence that incumbent‐fund liquidity is negatively affected when a new ETF is added to an asset class. The degradation in liquidity is even more severe whenever both funds follow the same benchmark. We also document a decline in primary‐market activity for the incumbent ETFs after the arrival of new competitors. Furthermore, increasing the number of funds in an asset class does not put downward pressure on fund management fees. Thus, the deterioration in market quality may not be offset by decreasing costs of fund ownership.  相似文献

Patent Breadth, Patent Life, and the Pace of Technological Progress   总被引:8,自引:1,他引:7  
In active investment climates where firms sequentially improve each other's products, a patent can terminate either because it expires or because a non-infringing innovation displaces its product in the market. We define the length of time until one of these happens as the effective patent life, and show how it depends on patent breadth. We distinguish lagging breadth, which protects against imitation, from leading breadth, which protects against new improved products. We compare two types of patent policy with leading breadth: (1) patents are finite but very broad, so that the effective life of a patent coincides with its statutory life, and (2) patents are long but narrow, so that the effective life of a patent ends when a better product replaces it. The former policy improves the diffusion of new products, but the latter has lower R&D costs.  相似文献

We analyse the consequences on agricultural markets of enlargement of the European Union (EU) to include the Czech Republic, Hungary, and Poland. We produce a market outlook up to 2010 for two enlargement scenarios assuming different policy restrictions on grain and dairy production in the acceding countries. Accession of the three Central and Eastern European countries (CEECs) leads to a permanent but moderate decrease in EU prices for most commodities. In the three acceding CEECs, domestic prices increase drastically, final consumption of agricultural products decreases in most instances, while production increases. Higher domestic prices in the CEECs reduce exports of most commodities to non‐union countries. Consequently, excess supplies are placed in stocks or exported to the original 15 member countries. Supply management mechanisms in the dairy and grain sectors would reduce the build‐up of surpluses in the new member states, but limit their ability to take advantage of the expanded market. Accession of the three CEECs would increase the CAP budget over its proposed maximum if area payments are extended to incoming crop producers.  相似文献

美国政府正在对美国几家世界顶尖的金融机构采取刑事调查。高盛有罪与否?我看高盛是做了令人厌恶的事情,但它的行为并不违法。我们赞同高盛,因为高盛发展了抵押业务,并将其设计成对冲基金中最赚钱的“噱头”。其次,高盛人也清楚,投资基金可能会给投资者带来巨大的损失。其实,高盛赢在其战略,它将盈利用在了冲抵投资的失败。  相似文献

The focus of this article is on multi-organizational cross-sector social partnerships (CSSP), an increasingly common means of addressing complex social and ecological problems that are too extensive to be solved by any one organization. While there is a growing body of literature on CSSP, there is little focus on collaborative strategic management, especially where implementation and outcomes are concerned. This study addresses these gaps by offering a conceptual model of collaborative strategic management, which is then tested through the use of two qualitative empirical cases of collaborative regional sustainable development strategies (CRSDS). The model augments previous collaboration models by highlighting two levels of implementation (the collaboration and the organizational levels) and by considering the different types of outcomes, and the feedback loops.  相似文献

Historically, work on multiple roots for the internal rate of return (PW = 0) equation focuses on tests for the root's uniqueness and interpreting the meaningfulness of computed roots. Instead, this article starts with problems that consist of P, A, and F cash flows. Then for all possible values of these cash flows, this article develops the boundary conditions for no, single, and multiple real roots of either positive or negative sign.

The results of characterizing these roots are applied to two examples as a foundation for conclusions about those multiple root problems and hypotheses about other problems with multiple roots. The first example is an important class of resource development projects that may require significant expenditures for environmental remediation at the conclusion of operation. The second example of buying versus leasing a home is often used to demonstrate the value of economic analysis to students.  相似文献

The impact of meat product recall events on consumer demand (beef, pork, poultry, and other consumption goods) in the USA is tested empirically. Beef, pork, and poultry recall indices are constructed from both the Food Safety Inspection Service's meat recall events and from newspaper reports over the period 1982–1998. Following previous product recall studies, recall indices are incorporated as shift variables in consumers’ demand functions. Estimating an absolute price version of the Rotterdam demand model, findings indicate that Food Safety Inspection Service's meat recall events significantly impact demand, and newspaper reports do not. Moreover, although elasticities related to recall events are significant they are small in magnitude relative to price and income effects. Any favourable effects on the demands of meat substitutes for a recall are offset by a more general negative effect on meat demand. The general negative effect indicates a shift out of meat to non-meat consumption goods.  相似文献
