THE SQUARED ORNSTEIN-UHLENBECK MARKET   总被引:2,自引:0,他引:2  
We study a complete market containing J assets, each asset contributing to the production of a single commodity at a rate that is a solution to the squared Ornstein-Uhlenbeck (Cox-Ingersoll-Ross) SDE. The assets are owned by K agents with CRRA utility functions, who follow feasible consumption/investment regimes so as to maximize their expected time-additive utility from consumption. We compute the equilibrium for this economy and determine the state-price density process from market clearing. Reducing to a single (representative) agent, and exploiting the relation between the squared-OU and squared-Bessel SDEs, we obtain closed-form expressions for the values of bonds, assets, and options on the total asset value. Typical model parameters are estimated by fitting bond price data, and we use these parameters to price the assets and options numerically. Implications for the total asset price itself as a diffusion are discussed. We also estimate implied volatility surfaces for options and bond yields.  相似文献

With expansion accelerating strongly since last summer, the world economy has overcome an extended period of weakness. The USA, driven by highly expansive fiscal policies, is once again proving to be an important locomotive for global economic development. The strong fiscal stimulus will diminish sharply this year, however. Can the recovery continue nonetheless? This is of importance for the euro area in particular, where exports have so far been the primary foundation of economic resurgence. Is the substantial appreciation of the euro jeopardising prospects of catching up with the rest of the world?  相似文献

One of the crucial intellectual and social challenges facing corporation leaders is to foster a new way of thinking about business and society which recognizes the multinational corporation as a key player in society's responsibility to support and maintain fairness in the global reorganization of markets. In order to establish a sound global social economy, we are in need of the organizing and directing principles of solidarity and subsidiarity. Both of these principles speak to the need of transforming our public and private institutions in such a way that all persons are placed in positions whereby they can share in the benefits of the newly-formed global economy.  相似文献

Value creation has long been hailed as the major objective of business firms by many management researchers. Some authors state that a firm must create value for its shareholders; some insist that value must be created not just for shareholders but also for all stakeholders. However, most discussions of value creation do not address an important question: "For whom the value is created?" The purpose of this paper is to take a first step to fill this void and propose a model of value creation along three dimensions: financial, nonfinancial, and time. It is hoped that the model will contribute to a better understanding of how strategic and operational decisions of managers may create value for some stakeholders while destroying it for others.  相似文献

Encouraged by a highly expansionary economic policy, the global economy is enjoying a rapid upturn. Utilisation of capacity is high in many sectors, particularly in the growth centres of the USA and East Asia, where China leads the field. With inflationary risks on the increase, most countries are now shifting the focus of economic policy. Fiscal policy in particular can be expected to provide little in the way of further stimulus. In addition, there has been a turnaround in interest rates in many countries. Yet how quickly can the monetary reins be tightened without jeopardising growth or endangering price stability?  相似文献

The purpose of this article is to show how moral imagination can be cultivated through meditation. Moral imagination was conceived as a three-stage process of ethical development. The first stage is reproductive imagination, that involves attaining awareness of the contextual factors that affect perception of a moral problem. The second stage, productive imagination, consists of reframing the problem from different perspectives. The third stage, creative imagination, entails developing morally acceptable alternatives to solve the ethical problem. This article contends that moral imagination can be cultivated through three kinds of meditation: non-discursive, semidiscursive, and discursive meditation. Part one shows how the seed of reproductive moral imagination is planted during sessions of nondiscursive meditation. Productive moral imagination, as will be shown in part two, is nurtured through semidiscursive meditation. Part three will demonstrate the flowering of creative moral imagination through discursive meditation. Reflection and small group discussion on each form of meditation will help to show business people how to cultivate moral imagination.  相似文献

Part 1 of this exploratory study demonstrated that for terminal, instrumental, and work values, supervisors could only accurately assess the extent to which their terminal values are congruent with their employees, whereas, employees could only accurately describe degrees of alignment with their supervisors' work values. Thus, supervisors appear to possess conscious awareness of the terminal values held by their employees and employees similarly possess conscious awareness of their supervisors' work values. Part 2 of the study examined what each of these two parties might do with their conscious knowledge concerning value congruence with the other member. Supervisor ratings and employee self-ratings concerning employee job performance, citizenship, climate fit, working relationship (LMX), and other issues, were correlated with supervisor terminal value congruence estimates and employee work value congruence estimates respectively. For supervisors, only one significant finding was noted, indicating a positive relationship between the supervisors' awareness of terminal value congruence with the employee and the supervisors' estimate of the employee's potential for future promotion. For employees, seven hypotheses received support demonstrating relationships between the employees' 0awareness of supervisor/employee work value congruence and self-ratings of work behaviours, citizenship behaviours, volunteerism behaviours, work climate behaviours, work climate attitudes, work climate organizational-wide attitudes, and the supervisor/employee working relationship. Implications for management and future research are discussed.  相似文献

This paper explores the American bankruptcy system -- especially the Chapter 11 code -- which since 1978 has allowed insolvent companies the opportunity to restructure and reorganise with the benefit of court protection from creditors. Particular attention is focused on asbestos companies, such as Johns--Manville, which have been among the most consistent and controversial filers for bankruptcy under Chapter 11. The history of asbestos and Chapter 11 is explored, against the backdrop of the burgeoning asbestos crisis, caused by increasing mortality and litigation. Some of the business and ethical issues involved are highlighted by examining in detail a recent bankruptcy (Federal Mogul/T&N in 2001) that has implications in both Britain and America. Chapter 11 bankruptcy is evaluated, particularly in the light of the trend towards similar mechanisms of insolvency in the UK, Europe and the rest of the world. It is concluded that, certainly as regards the experience with asbestos, Chapter 11 offers an inefficient and inequitable method of rehabilitating or rescuing failing businesses.  相似文献
