The paper studies general equilibrium in an economy with externalities, production and heterogeneous agents. The model developed builds on Brock [Brock, W.A., 1982. Asset prices in a production economy. In: McCall, J.J. (Ed.), The Economics of Information and Uncertainty. University of Chicago Press, Chicago, pp. 1–43] and Merton [Merton, R.C., 1987. A simple model of capital market equilibrium with incomplete information. Journal of Finance 42, 483–510]; it involves both a stock market and a market for loans, together with negative externalities produced by a subset of firms. Importantly, the technological production structure of the firms is reflected in the properties of the shares traded in the stock market. Agents are heterogeneous in their financial choices, potentially discriminating against the firms producing a negative externality. The model sheds light on the utility costs of the discriminating behavior and on the impact on the price of the stock issued by the firm which is responsible for the externality. The model is used to study the factors which may magnify or reduce the impact of discrimination. A set of discriminated firms may be seriously affected only if the discriminating investors command a large portion of overall wealth and/or they do not represent important diversification instruments. The model can be applied to understanding the effects of socially responsible investment, whereby investors discriminate against companies belonging to some sectors which are perceived as socially dangerous or unethical. 相似文献

Do We Really Want More Leaders in Business? 总被引:1,自引:0,他引:1
Andrea Giampetro-Meyer S.J. Timothy Brown M. Neil Browne Nancy Kubasek 《Journal of Business Ethics》1998,17(15):1727-1736
In this article, we focus on the concept of leadership ethics and make observations about transformational, transactional and servant leadership. We consider differences in how each definition of leadership outlines what the leader is supposed to achieve, and how the leader treats people in the organization while striving to achieve the organization's goals. We also consider which leadership styles are likely to be more popular in organizations that strive to maximize short run profits. Our paper does not tout or degrade any of these leadership theories. Instead, it points out which theories allow reason to play more than a minimal role in ethical decision-making, as well as those that are most consistent with a firm's desire to achieve efficiency in the short run. We explain our view that the way leadership is practiced in large, bureaucratic organizations suggests that ethics is often absent from the leader's decision-making process. Consequently, we suggest that before we engage in a meaningful dialogue about what kind of leaders we might really want in business, we must consider how much short-run profit we are willing to forego in exchange for more ethical corporate cultures. 相似文献

While most large companies around the world now have a code of ethics, reported ethical malpractice among some of these does not appear to be abating. The reasons for this are explored, using academic studies, survey reports as well as insights gained from the Institute of Business Ethics' work with large corporations. These indicate that there is a gap between the existence of explicit ethical values and principles, often expressed in the form of a code, and the attitudes and behaviour of the organisation. The paper suggests that two basic reasons appear to be at the heart of the problem: ineffective ethics programmes and deficiencies in corporate culture. The paper concludes that successfully embedded corporate ethical values requires well‐designed ethics policies, sustained ethical leadership and incorporation of ethics in organisational processes and strategy as part of an ethical culture at all levels of the organisation. It makes some practical suggestions on how this can be achieved. 相似文献

We present a new, global database on tourist destinations. The database differs from other databases in that it includes both domestic and international tourists; and it contains, for the most important destinations, data at national level as well as at lower administrative levels. Missing observations are interpolated using statistical models. The data are freely accessible on the internet. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献

This paper considers a single coefficient representation of the term premia relationship that appears in treasury bill yield curves. Term premia are defined as positive or negative maturity-dependent differentials versus the instantaneous nominal spot rate. The term premia function is developed in the context of the Cox, Ingersoll, and Ross [ 3 ] Risk-Averse Preferred Habitat Model and proxies for the degree of risk aversion exhibited by the universe of treasury bill investors at a point in time. Empirical results indicate that term premia are influenced by a set of macroeconomic variables in the expected manner. 相似文献

Evidence from many countries in recent years suggests that collateral values and recovery rates (RRs) on corporate defaults can be volatile and, moreover, that they tend to go down just when the number of defaults goes up in economic downturns. This link between RRs and default rates has traditionally been neglected by credit risk models, as most of them focused on default risk and adopted static loss assumptions, treating the RR either as a constant parameter or as a stochastic variable independent from the probability of default (PD). This traditional focus on default analysis has been partly reversed by the recent significant increase in the number of studies dedicated to the subject of recovery‐rate estimation and the relationship between default and RRs. This paper presents a detailed review of the way credit risk models, developed during the last 30 years, treat the RR and, more specifically, its relationship with the PD of an obligor. Recent empirical evidence concerning this issue is also presented and discussed.
