We explore whether audit partners’ attitude towards risk, as measured by their personal criminal convictions, are reflected in the composition of their client portfolios. Analyzing a unique dataset of Swedish audit partners’ criminal convictions, we find that the clients of audit partners with criminal convictions are characterized by greater financial, governance, and reporting risk than those of audit partners without criminal convictions. Also, clients of audit partners with criminal convictions pay larger audit fees, on average, than those of auditors without criminal convictions. 相似文献

Perennial crops require substantial initial investment in groundwork and planting, as well as a multiyear gestation period without commercial yield. Therefore, a crop's cycle (from planting to felling) should be long enough in order to cover the fixed cost and become profitable. The problem becomes involved when the cycle's duration is stochastic due to occurrence of uncertain event that terminates the cycle prematurely. Studying orchard management under stochastic drought events, we show that to each perennial crop that is profitable without drought hazard, there exists a critical drought hazard above which the crop turns loss making. We refer to this critical drought hazard as the crop's drought vulnerability index and show that it increases with the length of the gestation period, the ratio of fixed cost to average annual profit and the interest rate, and decreases with the natural (uninterrupted) cycle length. We then investigate the economic value of a stable water source, such as recycled water, that stabilizes the water supply and diminishes the drought hazard. An empirical application in northern Israel reveals that the stabilization value of recycled water due to its role in eliminating the drought hazard far exceeds its supply cost. 相似文献

Wildlife disease management strategies traditionally focus on lowering aggregate host density below a host-density threshold, reducing infectious contacts (when transmission is density-dependent) to reduce prevalence. The focus on aggregate host density is because controls such as harvests are typically nonselective with respect to disease status. Such nontargeted strategies increase control costs and may not optimally lead to eradication. We consider targeting an observable trait correlated with infection—gender. Two endogenous host-density thresholds emerge, in contrast to the exogenous thresholds arising in the ecological literature on multiple-host-pathogen problems. The ability to manage these thresholds reduces control costs and makes eradication optimal. 相似文献

Agro-terrorism is a hostile attack, towards an agricultural environment, including infrastructures and processes, in order to significantly damage national and international political interests. This article provides a framework for reducing agro-terrorism-related risks by either means of foresight (prevention) or early detection of exotic/foreign pathogenic agents and their dispersion patterns. It focuses on intention detection using overt data sources on the World Wide Web as they relate to agro-terrorism threats. The paper defines agro-terrorism, examines data characteristics, identifies weaknesses among the intelligence community that must be addressed, then integrates the classical intelligence cycle for early detection that may lead to prevention of such acts. 相似文献

This paper argues that while total short sale constraints are often introduced to rule out tax arbitrage, such constraints are both unrealistic and conceptually problematic. Instead, milder constraints are advocated, which prevent tax arbitrage while still allow short positions. It is demonstrated that a model with these constraints employed can support bond pricing as in the Miller equilibrium, although it leads to a richer set of tax clienteles. 相似文献

We empirically investigate valuations of Internet firms at various stages of the initial public offering (IPO) from two perspectives. First, we examine the association between the valuation of Internet IPOs and a set of financial and nonfinancial variables, which prior anecdotal or empirical evidence suggests may serve as value drivers. Second, we document differences in IPO valuations between Internet and non-Internet firms as well as across different stages in the IPO process—i.e., initial prospectus price, final offer price, and first trading day price—within each set of firms. Our primary two conclusions are as follows. First, there are noticeable differences between valuations of Internet and non-Internet firms, especially at the prospectus and final IPO stage. Specifically, the valuation of non-Internet firms generally follows the conventional wisdom regarding valuation: positive earnings and cash flows are priced, while negative earnings and negative cash flows are not. The valuation of Internet firms, however, departs from conventional wisdom, with earnings not being priced, and negative cash flows being priced perhaps because they are viewed as investments. This difference between the two classes of firms may be expected, given the age and unique nature of the Internet industry. Second, there are significant differences between the initial valuation of firms at the prospectus and IPO stage and their valuation by the stock market at the end of the first trading day. For non-Internet firms, the difference is largely ascribed to the relative offering size. For Internet firms, however, the differences are with respect to positive cash flows, sales growth, R&D, and high-risk warnings, in addition to the relative offering size. 相似文献

Manure Applications and Nutrient Standards 总被引:3,自引:0,他引:3

Because of environmental concerns, many states are regulating animal manure applications to crops. A conceptual model is presented to describe manure demand for crop nutrient application under alternative regulatory standards. Demand relationships are incorporated into a spatial equilibrium model to estimate welfare costs of phosphorus and nitrogen regulatory standards for manure applications. Model estimates for Virginia indicate that regulatory standards for manure application achieve large reductions in excess nitrogen and phosphorus and result in 5–15% welfare losses excluding nonmarket environmental valuation. 相似文献
