This note shows that the impact of an increase in product price on factor demand in the typical textbook depiction is overstated to the point of indicating that competitive firms demand factors even when marginal product is negative.  相似文献

The importance of evaluating a discipline system from an ethical perspective is considered. Disciplinary practices in contemporary organizations are frequently characterized by managers having to choose from among alternative courses of corrective action. Since the selected alternative may have serious consequences for the individuals involved, its rightness or wrongness is of concern. The pattern of these choices reflects the overall disciplinary practice of the organization, and is an issue that warrants attention from an ethical perspective. Basic schools of thought that influence contemporary discipline practices are discussed and suggestions are made for conducting an evaluation of the ethical nature of a discipline system.  相似文献

This paper examines the bank lending relations of a large sample of technology and nontechnology firms that went public during the 1996–2000 period. We use a unique hand-collected data set to examine the characteristics of firms that establish pre- Initial Public Offering (IPO) bank lending relations and whether post-IPO performance is related to the existence and size of pre-IPO banking relations. We find that the majority of IPO firms have banking relations before they go public. Firms with banking relations are older, more profitable or, in the case of tech firms, have lower losses, and are more likely to have funding from venture capitalists than firms without banking relations. We also find that banks lent aggressively to technology firms in the sense that current earnings and cash flows were significantly less important in determining banking relations for technology firms than for nontechnology firms. Consistent with the importance of so-called soft information in lending decisions, we find that, controlling for ex ante observable risk measures, there is a positive and significant relation between improvements in post-IPO operating performance and the existence and size of pre-IPO banking relations. Overall, our results indicate that firms with the best current and future prospects establish banking relations. Our findings provide an explanation as to why investors could interpret lending relations as a positive signal of firm quality.  相似文献

Concerns have been raised that insufficient funding has been affecting the delivery of elections in many countries. This paper presents a case study of England and Wales from 2010–2016. It demonstrates that many local authorities saw major real terms cuts and were increasingly over-budget. Those subject to cuts were less likely to undertake public engagement activities. State efforts to encourage voter participation may therefore be a casualty of austerity.  相似文献

Audit education is typically offered only to accounting majors. We argue that auditing provides a way of thinking that could serve as a framework for an accounting curriculam. We describe two parts of a course content that could be incorporated into an existing auditing course or a begining accounting course. The first section emphasizes accountability; the second emphasizes the role of the auditor in the accountability process. The concepts are best taught within an international paradigm that permits examination of various institutional environments.  相似文献

We examine the market power of a seller who repeatedly offers upgraded versions of a product. In the case of pure monopoly, the seller also controls compatibility across versions. In the case of an entrant who offers an upgrade, the incumbent seller also controls subsequent interoperability across versions. We argue that control of compatibility and interoperability does not allow an incumbent seller to charge a price premium relative to when such control is absent and, consequently, neither is a necessary source of market power.  相似文献

We develop and estimate a PC-industry specific model in which proxies for both discretion and non-discretion are used to partition loss reserve revisions into discretionary and non-discretionary components. The use of such proxies enables us to test directional hypotheses about the relations between the revision components and future profitability, risk and market value. We predict and find that discretionary revisions are negatively associated with future profitability, positively associated with firm risk, and negatively associated with market-to-book ratios. We predict and find that non-discretionary revisions are positively associated with future profitability and risk but are not associated with market-to-book ratios.  相似文献

The timing of prepayment: A theoretical analysis   总被引:1,自引:0,他引:1  
This article develops the analytical methods necessary to determine the prepayment patterns of a mortgage contract. The most obvious measure of how many years a mortgage is likely to last is the expected time to termination. It is this measure that we most fully explore. However, since the method employed is able to characterize the probability of prepayment in any given time period, the means is provided to determine any measure of the time to termination.  相似文献

Injection drug users (IDUs) transmit the human immunodeficiency virus (HIV) via both needle sharing and sex. Available interventions for this population have varying costs and effectiveness and focus on different risk behaviors. In this analysis, we look at two interventions. One is inexpensive, broad-based and provides modest risk reductions (street outreach (SO)); the other is narrowly focused, expensive and relatively effective (methadone maintenance). This analysis explores the effects of population risk behavior, intervention effectiveness, intervention costs, and decision constraints when allocating funds between these two interventions to maximize effectiveness. We develop a model of the spread of HIV, dividing IDUs into susceptibles (uninfected) and infectives, and separately portraying sex and injection risk. We simulate the epidemic in New York City for time periods from the mid-1980s to the early 1990s, and incorporate the behavioral effects of two interventions performed singly or in combination to find the allocation that maximizes the number of infections averted in the IDUs and their noninjecting sex partners, assuming interventions have increasing marginal costs. We find that the optimal allocation nearly always involves spending the maximum allowable amount on SO. This result is largely insensitive to variations in risk parameters, intervention efficacy, or cost. The model's structure, however, makes clear that many factors contribute to this insensitivity, namely the scope of the interventions, the dual drug/sex nature of HIV risk in the population, the asymmetry of sexual risk for men and women, and the potential benefits to nonIDUs.  相似文献
