Abstract
The problem of numerically pricing credit default index swaptions on a large number of names is considered. We place ourselves
in a stochastic intensity framework, where Ornstein-Uhlenbeck-type correlated processes are used to model both firms’ distance
to default and a macroeconomic state variable. Here the default of the firms’ follows the reduced-form approach and the (random)
intensity of the default depends on the behavior of the diffusion processes. We propose here a numerical method based on both
a Monte Carlo and a deterministic approach for solving PDEs by finite differences. Numerical tests demonstrate the efficiency
and the robustness of the proposed procedure. 相似文献

We investigate the role of contract volition and motives for accepting temporary employment in the relationship between precariousness of life and negative psychological symptoms in a sample of 275 Italian temps. Results suggest that the negative effect of contract volition on negative psychological symptoms is partially mediated by precariousness of life. A moderated mediation model shows that specific motives moderate the negative effects of contract volition on precariousness of life, so that when contract volition is higher, workers with weaker motives feel less precarious. This study broadens our understanding of temporary employment outcomes by showing that the negative consequences of precariousness of life seem to be less troublesome among temporary workers with higher contract volition and lower motivation. © 2018 ASAC.

Business firms have been explained as internal markets or as communities. To be sustainable, however, they need to reconcile these two constituting elements that have mainly been touted as opposite and part of a dualistic relationship. We suggest that organizations may, in alternative, view market and community as part of a duality, interdependent and mutually constituting processes that may not only contradict each other but also enable one another. The implications of a duality view for business ethics, which articulates market and community elements in a fruitful, mutually enabling relationship, are considered, and duality is presented as a way of transcending what is commonly viewed as opposition, moving organizations both in the direction of humane and competitive finalities. 相似文献

Pushing through a logical continuum of closed- to open-system views of organizations necessarily changes the conceptualization of a firm from a strongly bounded entity to a configuration of networks and sub-networks, which exists and operates in a larger systemic network configuration. We unfold a classification of management processes corresponding to views of the firm along the closed/open-systems continuum. We examine ethical issues that are likely to devolve from these classes of management processes, and we suggest typical means by which managers will attempt to control their firms’ exposure to such issues. The final class of management processes examined focuses on the achievement of outcomes that are mutually satisfactory in the set of networks and sub-networks that constitute the focal firm, and that support the sustainability of the whole system. The article contributes to organizational theory, business ethics, and computer and information ethics by providing a comprehensive analysis of the impact of managerial views of the firm and of networks – virtual, social, informational – on managerial processes and on our understanding of how business ethics issues are linked to perceptions of what a firm is, does, and can do. 相似文献

Modern public relations practices have been dominated by appeals to impulses, desires, and images that affect publics defined
predominantly in demographic terms. This paper argues that abandoning basic rhetorical assumptions about the ability of ordinary
people to engage in practical reason has serious ethical implications for the marketplace as well as for society in general.
The study applies recent rhetorical scholarship on issues of public discourse and rhetorical culture to public relations practices,
considering how rhetoric can contribute to more effective and ethical public discourse in our dominant modes of marketplace
communication. 相似文献

In this article we propose a lattice algorithm for pricing simple Ratchet equity-indexed annuities (EIAs) with early surrender risk and global minimum contract value when the asset value depends on the CIR++ stochastic interest rates. In addition we present an asymptotic expansion technique that permits us to obtain a first-order approximation formula for the price of simple Ratchet EIAs without early surrender risk and without a global minimum contract value. Numerical comparisons show the reliability of the proposed methods. 相似文献

This article analyzes the issue of organizational transparency through the lens of Thomas Aquinas’ ethics. It provides moral justification for current claims about corporate transparency and sheds light on the ethical values and virtues affecting information disclosure decisions. Transparency is conceptualized as an informational mechanism necessary for performing the virtues of truthfulness, justice, and prudence. This article extends the organizational transparency and corporate social responsibility literatures by providing an alternative moral justification grounded in virtue-based theory, which extends our understanding of the information disclosure decisions made by management. 相似文献
