An optimal insurance design problem under Knightian uncertainty

This paper solves an optimal insurance design problem in which both the insurer and the insured are subject to Knightian uncertainty about the loss distribution. The Knightian uncertainty is modeled in a multi-prior g-expectation framework. We obtain an endogenous characterization of the optimal indemnity that extends classical theorems of Arrow (Essays in the Theory of Risk Bearing. Markham, Chicago 1971) and Raviv (Am Econ Rev 69(1):84–96, 1979) in the classical situation. In the presence of Knightian uncertainty, it is shown that the optimal insurance contract is not only contingent on the realized loss but also on another source of uncertainty coming from the ambiguity.     

The currency of talent management—A reply to “talent management and the relevance of context: Towards a pluralistic approach”

In this paper we provide a commentary on the article in this Special Issue by Thunnissen, Boselie, and Fruytier on the relevance of context to the field of talent management. We concur that a more critical, pluralist approach to talent management scholarship is needed, that talent management should go beyond a mere economic exchange between talent and their employer, and that further research is needed to explore the link between macro, meso and micro level considerations. Thunnissen, Boselie, and Fruytier pose insightful questions about the contribution of talent management to the social and moral development of society and legitimating talent management at meso level. For us, these questions raise issues about the extent to which individual agency in ethical issues is possible in environments designed to regulate and control talent. We suggest that underexplored notions of strategic exchange and individual identity provide a richer picture of the talent employment relationship and raise a number of possible directions for future talent management research.     

The impact of limit order anonymity on liquidity: Evidence from Paris, Tokyo and Korea

This paper examines the impact of broker anonymity on bid-ask spreads in order driven markets. Previous theoretical research predicts that limit order anonymity results in deeper and more liquid markets. This paper examines this proposition using three natural experiments provided by Euronext Paris, the Tokyo Stock Exchange and the Korea Stock Exchange. Euronext Paris and the Tokyo Stock Exchange removed broker identifiers from limit orders on April 23, 2001 and June 30, 2003, respectively. In contrast, the Korea Stock Exchange introduced broker identifiers for limit order books on October 25, 1999. The results provide evidence that altering limit order anonymity has an impact on liquidity. Consistent with expectations, liquidity is enhanced by increased anonymity and adversely affected by decreased anonymity.     

No Small Hope: The Basic Goods Imperative

The continuing gender and race/ethnic pay gaps continue to be a matter of considerable concern. Using detailed NLSY data we examine the effects of a number of variables often thought to explain a large part of these gaps. Because the new variables explain some of the differentials our results provide no justification for ascribing all the remaining differentials to discrimination. On the other hand, they explain very little and therefore give no support to those who would discount the possibility of discrimination.     

Trustworthiness and interest rates: an empirical study of Italian SMEs

Trust is expected to reduce transaction costs and agency costs and thus influence the cost of credit for small businesses. Assessments of trustworthiness are based on the ability, benevolence and integrity of the owner manager. The study examines whether lending managers’ assessments of the trustworthiness of small and medium-sized enterprise (SME) owner managers are associated with the interest rate charged. Data were obtained from a survey of lending managers from small banks in North East Italy. Control variables and a vector of trustworthiness factors were collected on a random sample of customers, resulting in data for 365 small firms (74% response rate). Multivariate regression analyses provided evidence of a negative association between trustworthiness and interest rates. Banks, owner managers, policy makers and researchers should recognise the potential of trust to influence lending decisions and behaviour.     

Impact of Flexible Periodic Premiums on Variable Annuity Guarantees

In this article, we study the fair fee of a flexible premium variable annuity (FPVA), in which the policyholder can choose to pay periodic premiums during the accumulation phase instead of a single initial premium. We are able to express fair fees using a fast and accurate approximation based on bounds on the price of the FPVA. We identify scenarios that are particularly costly for the insurer. Our study could help insurers estimate the magnitude of typical underpricing when offering flexible-premium variable annuities with the same fee as the corresponding single-premium variable annuity.     

The Ethical Aftermath of a Values Revolution: Theoretical Bases of Change, Recalibration, and Principalization

Profound and wide-ranging values shifts among industrialized nations, first noted following World War II and measured on an ongoing basis since, have affected individual decision making in political, social, and institutional settings across the globe. Consequently, the adoption of this set of expansive values is having pronounced and measurable effects on organizational missions, standards, and activities. This change is particularly notable in terms of accountability practices, moral responsibility, and the distinction between ethical and unethical decision making. This article documents this change, the need for a recalibration of ethical standards, and the principalization of a new organizational values order. Future research on the implications of adopting expansive values in organizations is delineated.     

Performance Regularity: A New Class of Executive Compensation Packages

The ability of standard executive stock options to incite managers to adequately select the assets of their firm has been extensively questioned by academics and practitioners. However, very few alternatives exist or have been proposed to better control the investment strategies of top managers. The present article studies the evaluation and sensitivity of a new class of executive stock options well designed for the control of managers. Such packages are aimed at giving incentives to CEOs to maintain a regular performance over time and a stable volatility level. The importance and implications of the choice of the different parameters as well as their robustness with respect to standard financial criteria are examined. In brief, this article studies in a utility-based framework a new type of executive stock options that can be useful to protect and enhance the economic performance of corporations.
