Jonathan B. King 《Journal of Business Ethics》1993,12(2):105-116
Three general types of problems entail different strategies. Continuing to seek solutions to tame problems when we face messes, let alone wicked problems, is potentially catastrophic hence fundamentally irresponsible. In our turbulent times, it is therefore becoming a strategic necessity to learn how to solve the right problems.
Jonathan King is Associate Professor of Management at the College of Business at Oregon State University. His primary research interests are in the areas of moral philosophy and modern technology. His most important publications are Confronting Chaos and Common Knowledge of the Second Kind,Journal of Business Ethics (1989). 相似文献But then, you may agree that it becomes morally objectionable for the planner to treat a wicked problem as though it were a tame one, or to tame a wicked problem prematurely, or to refuse to recognize the inherent wickedness of social problems.

Jackknifing Bond Option Prices 总被引:2,自引:0,他引:2
Prices of interest rate derivative securities depend cruciallyon the mean reversion parameters of the underlying diffusions.These parameters are subject to estimation bias when standardmethods are used. The estimation bias can be substantial evenin very large samples and much more serious than the discretizationbias, and it translates into a bias in pricing bond optionsand other derivative securities that is important in practicalwork. This article proposes a very general and computationallyinexpensive method of bias reduction that is based on Quenouille's(1956; Biometrika, 43, 353360) jackknife. We show howthe method can be applied directly to the options price itselfas well as the coefficients in the models. We investigate itsperformance in a Monte Carlo study. Empirical applications toU.S. dollar swap rates highlight the differences between bondand option prices implied by the jackknife procedure and thoseimplied by the standard approach. These differences are largeand suggest that bias reduction in pricing options is importantin practical applications. 相似文献

Frictions, Heterogeneity and Optimality in Mortgage Modeling 总被引:1,自引:0,他引:1
The purpose of this article is to provide a unified framework for incorporating frictions into a theoretical options-pricing model (OPM) for mortgages. This article presents formulation for a frictions-adjustable mortgage model that integrates borrower heterogeneity while simultaneously preserving prepayment and default financial decisions. Our model demonstrates the flexibility of the OPM by simulating separate and concurrent effects of three categories of frictions on the mortgage and mortgage components. Researchers can use our example formulation to determine the effects of specific borrower characteristics on mortgage values without destroying the options theoretic framework. 相似文献

This paper examines whether the cross sectional variation in Australian share prices is partially explained by measures of firm size and ownership characteristics in a manner that is consistent with firms behaving in accordance with Merton's (1987) model of capital market equilibrium with incomplete information. Based on a sample of firms whose shares were traded on the ASX during 1995, we show that firms largely owned by less wealthy shareholders tend to have low stock prices, although this relation is not linear. In addition, larger, better–known, firms tend to have higher stock prices. These findings are consistent with prior evidence from US markets, and suggest the existence of a shareholder clientele effect in Australia that is related to the share price of the underlying firm. 相似文献

Trade-off Model of Debt Maturity Structure 总被引:3,自引:0,他引:3
In this paper, we suggest the trade-off model to explain the choice of debt maturity. This model is based on balancing between risk and reward of using shorter-term loans. Shorter-term loans have cost advantage over, but incur higher refinancing and interest rate risk than longer-term loans. Using the Compustat data, we show that the principal components of financial attributes are financial flexibility and financial strength. Therefore, only firms with greater financial flexibility and financial strength can use proportionately more short-term loans. We also document that financially strong firms take advantage of lower interest rates of short-term debt. They use proportionately more short-term loans when the term premium is high. The results of our study also provide evidence supporting the agency cost hypothesis, which is strongly supported by current literature. 相似文献

The number and severity of natural catastrophes has increased dramatically over the last decade. As a result, there is now a shortage of capacity in the property catastrophe insurance industry in the U.S. This article discusses how insurance derivatives, particularly the Chicago Board of Trade's catastrophe options contracts, represent a possible solution to this problem. These new financial instruments enable the capital markets to provide the insurance industry with the reinsurance capacity it needs. The capital markets are willing to perform this role because of the new asset class characteristics of securitized insurance risk: positive excess returns and diversification benefits.
The article also demonstrates how insurance companies can use insurance derivatives such as catastrophe options and catastrophe-linked bonds as effective, low-cost risk management tools. In reviewing the performance of the catastrophe contracts to date, the authors report promising signs of growth and liquidity in these markets. 相似文献

We provide evidence about the motivation for a parent–subsidiary governance structure by analyzing valuation effects of seasoned equity offerings by publicly traded affiliated units. Our results support Nanda's (1991) theoretical model which predicts equity offerings convey differential information about subsidiary and parent value. Subsidiary equity issuance has negative valuation effects on issuing subsidiaries and positive effects on parents, while parent equity issuance reduces issuing parent wealth and increases subsidiary wealth. Our evidence suggests that a parent–subsidiary organizational structure enhances corporate financing flexibility and mitigates underinvestment problems identified by Myers and Majluf (1984) . There is no evidence of subsidiary wealth expropriation. 相似文献
