会计信息与公司治理结构分析

公司治理结构与会计信息都产生于委托代理理论、契约理论和产权理论的需要,理论基础的交叉重叠使会计信息与公司治理结构具有内在的逻辑性。会计信息质量决定公司治理效率,目前由于会计信息的有效需求不足和供给质量不高导致信息供需不均衡,从而使会计信息与公司治理陷入恶性循环,本文通过剖析信息供需机制不均衡的原因,提出完善的对策和建议。

On the Non-Existence of Redundant Options

In a seminal paper, Ross (Q J Econ 90:75–89, 1976) shows that if security markets are resolving, then there exist (non-redundant) options that generate complete security markets. Complementing his work, Aliprantis and Tourky (2002) show that if security markets are strongly resolving and the number of primitive securities is less than half the number of states, then every option is non-redundant. Our paper extends Aliprantis and Tourky’s result to the case when their condition on the number of primitive securities is not imposed. Specifically, we show that if there exists no binary payoff vector in the asset span, then for each portfolio there exists a set of exercise prices of full measure such that any option on the portfolio with an exercise price in this set is non-redundant. Since the condition that there exists no binary payoff vector in the asset span holds generically, redundant options are thus rare. I am grateful to an anonymous referee for very helpful comments.

我国证券纠纷调解机制的完善和金融申诉专员制度合理要素的借鉴

我国新修订的《证券法》于2020年3月1日正式施行。作为资本市场根本法规,《证券法》新增第六章"投资者保护"可谓亮点之一,其中第94条规定"强制调解制度"在诉讼和仲裁之外为投资者提供了新的维权路径,加强对投资者的事后保护。但目前我国证券纠纷调解机制仍有诸多问题,例如法律条文碎片化、调解协议刚性不足、调解衔接机制不完善、调解机构体系混乱、监督机制不力等,这些弊病从根本上严重影响证券纠纷调解机制的制度设计和程序运行。本文拟通过分析英国金融申诉专员制度的成熟经验,为我国证券纠纷调解机制的完善和发展提出优化路径。     

Interest-only and principal-only mortgage strips as interest-rate contingent claims

Interest-only (IO) and principal-only (PO) mortgage strips are valued in a stochastic interest-rate environment. The prepayment rate of the underlying mortgages is affected by two considerations not present in the pure financially rational model: (1) The property owner's holding period is assumed to follow a Gamma distribution, resulting in the possibility of prepayment due to the sale of the property (i.e., prepayment that is too early based on market interest rates); and (2) borrowers are assumed to face heterogeneous transaction costs related to refinancing the existing mortgage, and delay refinancing when market conditions make it optimal to do so (refinancing too late). Properties of IO/PO strips are identified by the finite difference method.
