Consistency conditions for affine term structure models

Sufficient conditions for the application of the Feynman-Kac formula for option pricing for wide classes of affine term structure models in the jump-diffusion case are derived by generalizing earlier results for bond pricing in the pure-diffusion case The author is grateful to Mikhail Chernov and Darrel Duffie for useful discussions and suggestions.

Agency hazards and alliance portfolios

Prior research over several decades has catalogued many positive motives underlying firms' decisions to engage in joint ventures and other forms of alliances. In this empirical analysis, we investigate whether agency problems brought about by the separation of ownership and control also stimulate the development of firms' joint venture portfolios. By focusing on joint ventures, as opposed to diversification in general or acquisitions, we address the recent debate on agency theory's domain. Results from a sample of U.S. manufacturing firms' alliance portfolios offer supporting evidence, and comparable findings are obtained for international and domestic joint ventures. Agency hazards are also found to bring about extensions of firms' nonequity alliance portfolios in both the international and domestic settings. Copyright © 2005 John Wiley & Sons, Ltd.     

Insider Ownership and Firm Value: Evidence from Real Estate Investment Trusts

Real estate investment trust (REIT) provides a unique laboratory to study the relation between insider ownership and firm value. One, a REIT has to satisfy special regulations which weaken alternative mechanisms to control agency problems. Empirically, I find a significant and robust nonlinear relation between Tobin's Q and REIT insider ownership that is consistent with the trade-off between the incentive alignment and the entrenchment effect of insider ownership. Two, many REITs are Umbrella Partnership REITs (UPREITs) which have dual ownership structure. They have both common shares and Operating Partnership Units (OP units). Property owners can contribute their properties to the UPREIT in exchange for OP units. Their capital gains taxes remain deferred as long as they hold onto their OP units and the UPREIT does not sell the properties they contributed. OP units owners are locked in with the firm and have incentive to monitor firm management, but their interests diverge from the common shareholders because their tax bases are much lower. Consistent with the trade-off between positive monitoring effect of OP units and tax-induced agency costs, I find that UPREIT's firm value increases with the fraction of OP units, but the effect is significantly weaker for the UPREITs where insiders hold OP units.     

Optimal portfolio choice in the bond market

We consider the Merton problem of optimal portfolio choice when the traded instruments are the set of zero-coupon bonds. Working within a Markovian Heath–Jarrow–Morton model of the interest rate term structure driven by an infinite-dimensional Wiener process, we give sufficient conditions for the existence and uniqueness of an optimal trading strategy. When there is uniqueness, we provide a characterization of the optimal portfolio as a sum of mutual funds. Furthermore, we show that a Gauss–Markov random field model proposed by Kennedy [Math. Financ. 4, 247–258(1994)] can be treated in this framework, and explicitly calculate the optimal portfolio. We show that the optimal portfolio in this case can be identified with the discontinuities of a certain function of the market parameters.

市场制度的价值取向与经济结构的市场调整

本文试图说明,在现有的生产技术条件下,市场制度应体现什么样的价值取向,才能通过市场调整出合理的经济结构。文中通过模型对中国经济的产业结构、所有制结构以及产业结构和所有制结构之间的互动影响进行实证分析,发现从产业结构或所有制结构单方面地对经济结构进行调整,都无法使经济结构达到一种合理的状态。并且通过市场调整经济结构时,市场制度的价值取向将起到关键的作用。比较分析不同的市场制度价值取向下市场对经济结构的调整发现,只有当经济中形成一种国有经济不与民(资本和劳动)争利的制度环境,并且制度的价值取向侧重于保护资本利益,但同时兼顾劳动利益时,市场才能调整出合理的经济结构。

Ownership concentration and bank risk: international study on acquisitions

This paper explores the effects of different types of bank ownership concentration on changes in bank risk during acquisition years. Using multi-country data from 2000 to 2006, during which market failures caused by various crises and government interventions are less influential to acquisition decisions, we collect 505 banking acquisition deals from 23 countries to examine which type of ownership concentration (such as financial intermediary, capital investor, non-financial, and state ownership) brings larger changes to an acquirer’s risk from pre-acquisition year to post-acquisition year (including non-performing loans, capital adequacy ratio, loan loss reserve, and credit rating). The empirical analyses show that acquirer banks with a concentration of shares owned by financial intermediaries and non-financial firms experience larger risk changes during acquisition years. In contrast, the risk changes of acquirer banks with a concentration of capital investors and state ownership are lower. Robustness checks from the random effect estimation, instrumental variables model, reverse causality, and different subsamples of (non-)U.S. or different levels of regulation enforcement confirm these results.
