The relation between sunspot effects and multiplicity in incomplete markets models with numeraire assets

This paper considers the necessity and sufficiency of multiple certainty equilibria for sunspot effects, and shows that neither implication is valid. This claim is made for models with incomplete markets and numeraire assets. First, I prove that a multiplicity of certainty equilibria is neither necessary nor sufficient for sunspot effects by way of two counter-examples. Second, I verify over an entire subset of economies that equilibrium with sunspot effects can never be characterized as a randomization over multiple certainty equilibria.     

Cross-border acquisitions by Indian multinationals: Asset exploitation or asset augmentation?

This paper examines cross-border acquisitions by Indian multinationals and places them in the context of Emerging Country Multinationals. It tests hypotheses based on internalisation theory and the resource based view to ask if these firms are asset exploiting or asset augmenting in their takeover behaviour. Internal financial and technological resources are found to be important explanatory variables, as is asset seeking; of brands, technology and market access. The home environment in India allows firms to amass profits, to manage in a culturally diverse setting and to develop asset bundling skills. All these factors are significant in determining cross-border acquisitions.     

Family Hardship and the Growth of Micro and Small Firms in Indonesia

I examine what happens to the total assets of micro and small firms in Indonesia when their owners experience hardship such as the death or sickness of family members, crop losses, or natural disasters. Using a representative sample of firm owners, I find that deaths of family members reduce the assets of such firms, that the adverse effects of these are long-lasting and economically large, and that the smaller the firms the greater the magnitude of these effects. There is no evidence, however, that the sickness of family members, crop losses, or natural disasters reduce firms’ assets. These results suggest that only severe family hardship impedes the growth of micro and small firms.     

在抽象与具体中回归实践的理论——与王南湜教授商榷

对于理论与实践的关系问题,长期以来哲学家们从理论哲学的角度出发,最终把理论引向一种神秘主义,造成理论与实践之间的割裂,因此从实践哲学的角度探讨这一问题是十分必要的。理论本身属于实践的依据在于其＂同根性＂＂目的性＂和＂广延性＂,理论活动的抽象性造成了理论与实践之间的距离。哲学这种理论只有回归实践,才能找到自己的＂阿基米德点＂,才是真正意义上的哲学。     

Valuing catastrophe derivatives under limited diversification: A stochastic dominance approach

We present a new approach to the pricing of catastrophe event (CAT) derivatives that does not assume a fully diversifiable event risk. Instead, we assume that the event occurrence and intensity affect the return of the market portfolio of an agent that trades in the event derivatives. Based on this approach, we derive values for a CAT option and a reinsurance contract on an insurer’s assets using recent results from the option pricing literature. We show that the assumption of unsystematic event risk seriously underprices the CAT option. Last, we present numerical results for our derivatives using real data from hurricane landings in Florida.     

解析公司董事之注意义务

公司董事会中心主义的勃兴,致使董事权力与责任的制衡备受关注,各国纷纷加强了对董事义务与责任的规制,以防止董事权力的滥用和督促董事尽其义务实现公司利益的最大化。这种形势在我国也同样存在,然而遗憾的是我国在董事注意义务立法方面存在过于粗糙和模糊的缺陷,难以适应我国公司实践的发展需要。文章主要通过比较研究方法,对董事注意义务的完善提出适用于我国的制度,对商业判断原则和浪费公司财产规则在我国的未来命运做出权衡。

Pricing American options written on two underlying assets

This paper extends the integral transform approach of McKean [Ind. Manage. Rev., 1965, 6, 32–39] and Chiarella and Ziogas [J. Econ. Dyn. Control, 2005, 29, 229–263] to the pricing of American options written on more than one underlying asset under the Black and Scholes [J. Polit. Econ., 1973, 81, 637–659] framework. A bivariate transition density function of the two underlying stochastic processes is derived by solving the associated backward Kolmogorov partial differential equation. Fourier transform techniques are used to transform the partial differential equation to a corresponding ordinary differential equation whose solution can be readily found by using the integrating factor method. An integral expression of the American option written on any two assets is then obtained by applying Duhamel’s principle. A numerical algorithm for calculating American spread call option prices is given as an example, with the corresponding early exercise boundaries approximated by linear functions. Numerical results are presented and comparisons made with other alternative approaches.
