夫妻共同遗嘱的效力及其立法建议

夫妻共同遗嘱在本质上属于共同法律行为。立法应有条件地承认共同遗嘱的效力,从法律上确认夫妻共同遗嘱的法律地位,并明确规定共同遗嘱的适用范围、适用主体、遗产范围、生效和失效、法律效力、变更与撤销以及执行等,从主体和内容两方面对夫妻共同遗嘱的适用和操作进行必要的规范。

利益衡量视角下的善意第三人与隐名共有人的出路探究

通过一典型案例可见不动产善意取得制度不能有效保护夫妻共有财产中隐名共有人的合法权利。揭示该问题产生的原因,并从善意第三人和隐名共有人利益衡量角度,设计出保护隐名共有人的制度平衡策略:增加第三人的注意义务,由律师负责相关审查来减轻国家赔偿责任和明确隐名共有人权利。     

“港口-产业-城市”复合系统协调度模型

分析了＂港口-产业-城市＂复合系统（port-industry-citycomposite system,以下简称PICCS）的特性,认为PICCS是具有耗散结构特征的开放系统。依据协同原理,构建了PICCS协调度模型,运用该模型计算连云港市PICCS的协调度。结果表明,PICCS协调度模型能够定量化地显示PICCS的协调发展状况,并找出PICCS发展过程中存在的主要问题,从而为港口地区港口、产业、城市协调发展机制的建设以及社会经济宏观发展目标的制定提供数据支持与决策依据。     

海洋综合执法模式的比较研究

海洋综合执法是克服海洋分散执法弊端的必然选择,目前我国海洋综合执法模式可以分为多元联合执法模式、一元统一执法模式和多元一体化执法模式,这三种模式在内涵和运行机制上都有显著区别,也各具自身的优势和不足,通过比较分析,可以为我们全面掌握海洋综合执法模式,以及在执法中如何选择海洋综合执法模式提供有益参考。     

The assignment of call option rights between partners in international joint ventures

We examine call option rights as a contractual clause in international joint ventures (IJVs) and propose that the assignment of the call option right in an IJV is determined by certain ex ante asymmetries between the partners. Results show that between the two partners in an IJV, the firm with greater complementarity with the venture and greater prior IJV experience is more likely to hold the call option right; in addition, the firm's contractual choice on the call option right and its ownership choice on a greater initial equity stake are substitutive. Our focus on explicit call options advances the real options theory of collaborative agreements, and our results also highlight that option rights be considered an important part of alliance design.

Diversification,Performance, and the Corporate Life Cycle

This paper investigates the relation between the extent of diversification in firms and their performance at different life cycle stages. To illustrate the joint endogeneity of diversification and performance, we treat both the extent of diversification and firm performance as endogenous variables in a simultaneous equation system. Empirical results reveal that corporate diversification erodes firm value. Overall, firms in their growing stages experience a significant diversification discount; however, mature firms do not show such findings. Although unrelated diversification leads to trading at a discount in all growing and mature firms, conversely, related diversification exhibits an evident premium in mature firms.     

Cooperation In R&D With Spillovers And Delegation Of Sales ∗

Cooperation in several phases of the innovation process is viewed by antitrust authorities with suspicion. They face the dilemma between providing the right incentives for the appro-priability of returns to R&D and the risks of diminishing product market competition. The current legislation in the European Union and the United States gives special treatment to cooperation in R&D and the joint exploitation of results (extended cooperation).

We study several collusive regimes for a class of examples in which vertical relations are explicitly introduced. Regarding antitrust policy implications we fmd that: a) there is an ana-lytical justification to a ‘rule of reason’ treatment for extended cooperation in research joint ventures and, b) individual exemptions, though restrictive of competition, might be welfare improving.     

Better cross hedges with composite hedging? Hedging equity portfolios using financial and commodity futures

Unless a direct hedge is available, cross hedging must be used. In such circumstances portfolio theory implies that a composite hedge (the use of two or more hedging instruments to hedge a single spot position) will be beneficial. The study and use of composite hedging has been neglected; possibly because it requires the estimation of two or more hedge ratios. This paper demonstrates a statistically significant increase in out-of-sample effectiveness from the composite hedging of the Amex Oil Index using S&P500 and New York Mercantile Exchange crude oil futures. This conclusion is robust to the technique used to estimate the hedge ratios, and to allowance for transactions costs, dividends and the maturity of the futures contracts.
