This paper investigates if a firm’s ethical reputation, in conjunction with its governance, affects its standing within financial markets. A firm`s ethical reputation, as measured by ethical failures, arises from its involvement in ethical violations and incidents while a comprehensive index proxies for governance. We assess a firm’s standing within financial markets through two complementary perspectives, i.e., the level of information asymmetry between managers and investors, as inferred from analyst forecast dispersion and analyst forecast error, and the relation between a firm’s earnings and its stock market valuation or return (value relevance). Our results suggest that a firm`s ethical reputation affects financial analysts’ forecasts as well as the stock market value assigned to its reported earnings. Moreover, it appears that corporate governance moderates such relations, with strong (weak) governance compensating for a weak (strong) ethical reputation. Overall, our evidence shows that ethical failures do not seem to pay. 相似文献

Visual object processing in infancy is often described as proceeding from an early stage in which object features are processed independently to a later stage in which relations between features are taken into account (e.g., Cohen, 1998). Here we present the Representational Acuity Hypothesis, which argues that this behavioral shift can be explained by a developmental decrease in the size of neural receptive fields in the cortical areas responsible for object representation, together with a tuning to specific object features. We evaluate this hypothesis with a connectionist model of infant perceptual categorization. The model shows a behavioral shift in featural to relational processing consistent with similar results observed in the infant categorization experiments of Younger (1985) and Younger and Cohen (1986). 相似文献

This paper defines the phenomenon of data mining in econometrics and discusses various outcomes of and solutions to data mining. Both classical and Bayesian approaches are considered, each with notable advantages and disadvantages, and with the choice of loss function affecting critical values. Illustrative examples include variable addition and exclusion in a standard linear regression model, the choice of lag structure in a dynamic single equation, and specification in a simultaneous equations model. 相似文献

A key determinant of the efficiency of a surveillance system for exotic mites is whether an incursion might be detected sufficiently quickly to allow successful management actions to occur. To assess this possibility we have developed a spatial modeling system and synthesized knowledge of honeybee and mite behavior to explore the potential spread of exotic mites and the likelihood of their detection in sentinel hives. We find that increasing the number of hives and the efficiency of the detection method are the most effective means of improving the time to detection. 相似文献

The role of assortment planning and pricing in shaping sales and profits of retailers is well documented and studied in monopolistic settings. However, such a role remains relatively unexplored in competitive environments. In this study, we study equilibrium behavior of competing retailers in two settings: (i) when prices are exogenously fixed, and retailers compete in assortments only; and (ii) when retailers compete jointly in assortment and prices. For this, we model consumer choice using a multinomial Logit, and assume that each retailer selects products from a predefined set, and faces a display constraint. We show that when the sets of products available to retailers do not overlap, there always exists one equilibrium that Pareto‐dominates all others, and that such an outcome can be reached through an iterative process of best responses. A direct corollary of our results is that competition leads a firm to offer a broader set of products compared to when it is operating as a monopolist, and to broader offerings in the market compared to a centralized planner. When some products are available to all retailers, that is, assortments might overlap, we show that display constraints drive equilibrium existence properties. 相似文献

The theoretical rationale of this study is that conditions associated with divorce reside outside the family within a broader social system where the family finds itself located. The absence of major differences in divorce law from one place to another within the Soviet Union makes it possible to explore this hypothesis by examining areal differentials in divorce rates. Crude divorce rates and crude marriage rates for 1960 have been published in Vestnik Statistiki for 109 political-administrative areas in the Soviet Union. Several indicators of modernization are available for the same areas from the 1959 U.S.S.R. Census of Population. About 80 per cent of the variation among areas with respect to the crude divorce rate is accounted for by six variables: the crude marriage rate, the percentage of urban population, and the employee-worker ratio in the labor force, each of which is positively associated with the divorce rate; and the proportion of poorly educated women, the ratio of children to adult males, and the mean household-family size, each of which is negatively associated with the divorce rate. 相似文献

A modern method for (partial) acquisitions is the so called creeping-in tactic. In this procedure the acquirer uses cash settled equity swaps to undermine WpHG notification requirements systematically until she holds at least 30% of the voting rights in the target company. In this case the acquirer has the obligation to submit a mandatory takeover bid for the remaining outstanding shares. In many cases acquirers are not interested in a complete acquisition of the target company but rather want to make use of low shareholder presence levels during the general assembly and therefore have the opportunity to significantly influence fundamental decisions like, e.g. allocation of the net income, corporate actions etc. The mandatory takeover bid has to be equal at least to the three months average share price. At first glance, this involves a high risk of an unintentional acceptance by the targets?? shareholders. The goal of this paper is to analyze the effectiveness of the mandatory takeover bid. We show that with a temporal shift of the mandatory takeover bid to a point in time when the share price is above the three months average share price an unintentional acceptance is virtually impossible. In a logit-regression company specific context factors for the acceptance risk are indentified and rejected. 相似文献
