论法律不完备性与政府介入期货市场 总被引:3,自引:0,他引:3
孙秋鹏 《河南金融管理干部学院学报》2005,23(4):112-115
在期货市场上,法律不完备性问题表现得较为突出,法律对于侵害行为的阻吓作用非常有限、期货市场法律的不完备性,主要取决于期货市场的特点和性质。政府采取相关的监管方式管理期货市场非常必要,监管的介入需要满足标准化和损害(外部性)足够高的条件。政府管理期货市场立法和法院执法的作用不可或缺,但更主要的是采用监管的方式。 相似文献

文章通过泰尔指数发现从1990年到2005年,河南省区域经济的差距处于一个快速扩大的阶段。通过定量分析发现,河南省区域经济发展水平和发展速度与农业生产具有一定的负相关性,通过定性和定量分析发现,农业产业化对区域差距缩小具有一定的作用,但不起主要作用,一是由于目前河南省农业产业化水平相对还是比较低,农业收入还仅仅停留于农产品的买卖价格,工资性收入所占比重过低,二是农业产业化龙头企业带动能力还是比较弱,带动面小,限制了农区经济的发展水平和速度,最后提出了几点建议。 相似文献

This paper investigates the potential disadvantages of the secondary markets for executive stock options (ESOs). The benefits of such markets are evident, but they might also have negative effects for shareholders. Executives might, for example, use inside information to time their ESO selling. We investigate two personal motives of managers that can be assumed to affect their optimal selling decision, that is, managers' personal portfolio management issues and the use of inside information. We explore these motives by analyzing unique data from Finland, where there are secondary markets for ESOs. The results of the study support the traditional portfolio diversification hypothesis according to which managers tend to sell their ESOs when holding an ESO is equivalent to holding the underlying stock; that is, in such a case a manager's wealth is closely tied to the stock price of the firm. With respect to the use of inside information the results indicate that ESO selling activity is not related to future stock price behaviour, suggesting that managers do not use inside information to determine the selling time of their ESOs. These results imply that the existence of secondary markets for ESOs does not weaken the usefulness of ESOs as the management compensation, although the benefits of such markets are evident. 相似文献

The intrinsic value approach amortizes over the life of the option, the difference between the stock price on the date of the grant and the exercise price of the option. The fair market value approach amortizes over the life of the option, the market value of stock options on the date of the grant. These approaches do not reflect the changes in the option–based compensation cost after the grant date. This paper proposes an economic cost approach that not only adjusts for the changes in the value of the options during its life but also records the issuance of the stock at fair market value on the exercise date. 相似文献

American-style Indexed Executive Stock Options 总被引:3,自引:0,他引:3
Peter Løchte Jørgensen 《European Finance Review》2002,6(3):321-358
This paper develops a new pricing model for American-style indexed executive stock options. We rely on a basic model framework and an indexation scheme first proposed by Johnson and Tian (2000a) in their analysis of European-style indexed options. Our derivation of the valuation formula represents an instructive example of the usefulness of the change-of-numeraire technique. In the paper's numerical section we implement the valuation formula and demonstrate that not only may the early exercise premium be significant but also that the delta of the American-style option is typically much larger than the delta of the otherwise identical (value-matched) European-style option. Vega is higher for indexed options than for conventional options but largely independent of whether the options are European- or American-style. This has important implications for the design of executive compensation contracts. We finally extend the analysis to cover the case where the option contracts are subject to delayed vesting. We show that for realistic parameter values, delayed vesting leads only to a moderate reduction in the value of the American-style indexed executive stock option. 相似文献

A sample of firms where employee stock options and other long‐term incentives are absent but an annual bonus is required is examined. A positive relation is found between firm equity value and stock bonus but not cash bonus. The positive relation is stronger when the firm has greater investment opportunities. Additionally, the relation is shown to be nonlinear in the sense that the marginal effect of stock bonus on equity value is positive but decreasing (negative) when the stock bonus is below (above) the breakpoint. Overall, the annual stock bonus is valued positively by investors even though it is linked to the firm's contemporaneous but not future performance. 相似文献

This paper investigates the causal links between stock market performance and consumption for five Asian economies by applying the bound tests of Pesaran et al. and lag augmented VAR of Toda and Yamamoto . We find two‐way causal relationships between stock market performance and consumption in the cases of Hong Kong and Taiwan in the long run. The existence of such two‐way causal links indicates that stock market performance and consumption mutually affect each other, implying that the previous studies may have overestimated the wealth effect of the stock markets without taking account of the reverse causation from consumption to the stock markets. The short‐run effect of the stock market on consumption is more visible than the long‐run effect in most of the sample economies, suggesting that changes in consumption directly reflect stock market fluctuations. 相似文献
