金融政治经济学的新视野

各国的公司、信贷和证券市场制度差别很大。而且 ,即使同样的制度在各国的履行程度也不尽相同。经济学家还不能完全理解这种国际差别存在和继续存在的原因。站在金融政治经济学角度对上述问题进行研究 ,则能得出一系列十分具有解释力的经验性规律。金融政治经济学模型中 ,监管及其履行被看作是社会和经济团体之间权力调和的结果。本文分析了金融政治经济学在公司财务、银行业和证券市场三大领域中的应用。

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.

Planning Your Own Debt

We model the Danish market for mortgage backed securities with a two-factor interest rate model and use a stochastic programming approach to analyse how an individual home-owner should initially compose and subsequently readjust his mortgage in an optimal way. Results show that the 'rules of thumb' used by financial institutions are reasonable, although best suited for more aggressive mortgagors, for whom the delivery option is of some value. More risk-averse investors should also re-adjust frequently, but use more diversified portfolios. Results are insensitive to whether a one- or two-factor model is used, provided the former is suitably calibrated.

法国公开要约收购制度的最新改革——以2006年《公开要约收购法》为中心

2006年3月31日，依欧盟转化《要约收购指令》之要求，法国颁布了《公开要约收购法》，对现有的公开要约收购制度进行了多方位、深层次的改革。从宏观上看，此次改革主要涉及四个方面，即金融证券管理局监管范围的改革、强制要约收购制度的改革、要约透明机制的改革以及反要约收购防御措施的改革。尽管改革的效果仍有待评估，但法国在此次改革中所体现的提高欧盟范围内企业竞争力的决心和表率作用无疑为欧盟经济一体化注入了新的活力。     

Disentangling Managers’ and Analysts’ Non‐GAAP Reporting

Researchers frequently proxy for managers’ non‐GAAP disclosures using performance metrics available through analyst forecast data providers (FDPs), such as I/B/E/S. The extent to which FDP‐provided earnings are a valid proxy for managers’ non‐GAAP reporting, however, has been debated extensively. We explore this important question by creating the first large‐sample data set of managers’ non‐GAAP earnings disclosures, which we directly compare to I/B/E/S data. Although we find a substantial overlap between the two data sets, we also find that they differ in systematic ways because I/B/E/S (1) excludes managers’ lower quality non‐GAAP numbers and (2) sometimes provides higher quality non‐GAAP measures that managers do not explicitly disclose. Our results indicate that using I/B/E/S to identify managers’ non‐GAAP disclosures significantly underestimates the aggressiveness of their reporting choices. We encourage researchers interested in managers’ non‐GAAP reporting to use our newly available data set of manager‐disclosed non‐GAAP metrics because it more accurately captures managers’ reporting choices.
