Contracting and Reporting Conservatism around a Change in Fiduciary Duties*

We exploit an influential 1991 Delaware court ruling to examine simultaneously two types of conservatism that play important roles in resolving creditor–owner agency conflicts: contracting conservatism and reporting conservatism. The ruling expanded managerial fiduciary duties in favor of creditors for Delaware-incorporated firms in the vicinity of insolvency. In those firms, following the ruling, debt contracts are less likely to include conservative adjustments to accounting numbers used for covenant compliance (i.e., contracting conservatism decreases), while public financial reporting becomes more conservative (i.e., reporting conservatism increases). The decrease in contracting conservatism is concentrated in firms that exhibit a greater increase in reporting conservatism, suggesting that reporting conservatism is more cost-effective in resolving agency conflicts. In addition, the substitution effect is more pronounced in firms facing greater business uncertainty and firms with greater board independence.     

Relative risk aversion, relative prudence and comparative statics under uncertainty: The case of (μ, σ)‐preferences

From the expected‐utility approach, relative risk aversion being smaller than one and relative prudence being smaller than two emerge as preference restrictions that fully determine the optimal responses of decisions under uncertainty to certain shifts in probability distributions. We characterize the magnitudes of relative risk aversion and relative prudence in terms of the two‐parameter, mean‐standard deviation approach. We demonstrate that this characterization is instrumental in obtaining comparative static results in the two‐parameter setting. We further relate our findings to the results in the expected‐utility framework.     

Decreasing absolute prudence: Characterization and applications to second-best risk sharing

In this paper, we provide two basic properties of utility functions u which exhibit decreasing absolute prudence i.e. (− u/u″)′ ≤ 0. These properties are used to examine the allocation of risks in an economy when some agents bear non-transferable risks. We show that it is fair Pareto-efficient to let those with a non-transferable risk bear relatively less of the transferable risk in the economy if and only if absolute prudence is decreasing. In another model, there is a complete set of contingent markets, but some agents have no direct access to them. We examine the fair efficient allocation of risk in a pool gathering a trader and a non-trader. Decreasing absolute prudence provides an upper bound to the share of the pool's risk that should be borne by the trader.     

EXPORT AND HEDGING DECISIONS UNDER CORRELATED REVENUE AND EXCHANGE RATE RISK

This paper examines the behaviour of a competitive exporting firm under joint revenue and exchange rate risk. The firm can trade unbiased currency futures contracts for hedging purposes. We show that neither the separation theorem nor the full‐hedging theorem holds when the revenue shock prevails. If the correlation between the revenue shock and the random spot exchange rate is non‐positive, the firm optimally produces less than the benchmark level when the revenue shock is absent. If, in addition, the firm is prudent, the optimal futures position is an under‐hedge. Finally, we derive sufficient conditions under which the firm's optimal output level is higher in the presence than in the absence of the revenue shock. Operational hedging and financial hedging as such interact in a complicated way to better cope with the multiple sources of uncertainty faced by the firm.     

New development: The protective role of conservatism in public sector accounting

This article picks up a discussion in international business accounting about the appropriate definition and use of conservatism (or prudence) and calls for a similar discussion in public sector accounting. If financial reports present an overly optimistic situation, politicians might use them to justify spending public money that is not there, risking the sustainability of services and ‘borrowing’ from future generations.

Optimal Insurance Against Climatic Experience

An optimal insurance contract against a climatic risk is derived in the presence of an uninsurable and dependent aggregate production risk. The optimal design depends on the stochastic dependency between both sources of uncertainty and on the producer's attitude towards risk, especially on his prudent behavior. Rational weather insurance purchasing decisions are also derived. The prudent producer responds to actuarially fair weather insurance by increasing his exposure towards risk.     

Diffidence Theorem, State-Dependent Preferences, and DARA

C. Gollier (The Economics of Risk and Time. Cambridge: MIT Press, 2001) has developed a standard technique based on the diffidence theorem. This theorem provides a very simple instrument to solve relatively sophisticated problems when preferences are state-independent. The object of this article is to show that the theorem is also very useful to derive significant results with state-dependent preferences. Using the reference set notion and an extension of the diffidence theorem, we establish formally necessary and sufficient conditions on the reference set, in order to obtain prudence and decreasing absolute risk aversion. Examples of DARA utility functions compatible with non-linear reference sets are presented in the Appendix.     

Business Ethics versus Economic Incentives:<Emphasis Type="Italic">Contemporary Issues and Dilemmas</Emphasis>

Contemporary economic thought presumes that individuals in a society always act according to their self-interest or private economic incentives, while important ethical motivations for action, such as a concern for others and public interest, are largely ignored. This paper is based on my experience of teaching an undergraduate course that highlighted the divergence between economic incentives and ethical motives for action in present-day life and business. Teaching tools such as lectures, case and group discussions were employed to address important ethical dilemmas of individuals and managers in contemporary societies. Readings underscored the evolving relationship of business ethics and economic incentives, and the relevance of ancient ethical principles (e.g., Ethics of Interdependence, and Ethics of Prudence and Self-Development) to present-day business ethics. The course emphasized the imminent need in contemporary societies to reduce the divergence between economic incentives and ethical motives for action, and called for a greater understanding of business ethics today, given the complex ethical concerns that managers confront in the current global environment.     

关于宏观审慎监管基础问题的思考

宏观环境对于金融定价具有基础性作用,定价基准的重大变化是系统性风险积累和爆发的重要根源。当前国际社会寄希望于通过宏观审慎监管来达到有效防范系统性风险的目的,主要是基于金融体系内部相互作用来着手解决内部关联性问题与顺周期问题,而对于决定金融定价基础的宏观环境重视不足或是缺少调节能力。传统的宏观政策在理念上、政策实践上对促进金融稳定均存在不足之处,宏观政策与宏观审慎监管的协调成为防范系统性风险的薄弱环节。为有效地防范系统性金融风险,有必要强调宏观政策和宏观审慎监管的协调配合。
