This paper extends the static hedging portfolio (SHP) approach of  and  to price and hedge American knock-in put options under the Black–Scholes model and the constant elasticity of variance (CEV) model. We use standard European calls (puts) to construct the SHPs for American up-and-in (down-and-in) puts. We also use theta-matching condition to improve the performance of the SHP approach. Numerical results indicate that the hedging effectiveness of a bi-monthly SHP is far less risky than that of a delta-hedging portfolio with daily rebalance. The numerical accuracy of the proposed method is comparable to the trinomial tree methods of  and . Furthermore, the recalculation time (the term is explained in Section 1) of the option prices is much easier and quicker than the tree method when the stock price and/or time to maturity are changed.  相似文献

Inward technology licensing (ITL) is often viewed as an important strategy adopted by firms to achieve innovation. However, relatively limited research has focused on evaluating the contribution of ITL to firm performance. The gap is all the more surprising since the benefits of external technology acquisition on innovation output have been emphasized in a lot of the literature. This study therefore sets out to investigate the extent to which the investment of ITL by firms affects their performance. In view of the relative abundance of data on variables for a longitudinal investigation, this analysis concentrates on the electronics-manufacturing industry. The longitudinal sample allows this examination to control the more extraneous effects and to provide more convincing evidence for examining the relationship of ITL and firm performance. A total of 341 Taiwanese electronics-manufacturing firms balanced over the period from 1998 to 2002 is taken as the analytical sample. The basic statistics indicate that acquiring technology externally shows an increasing tendency within the firms. The analyses, from the least square dummy variable method, reveal that ITL per se does not provide a significant contribution to firm performance; however, the positive impact of ITL on their performance increases with the level of the firms' internal research and development (R&D) efforts. Both the checks for robustness and the split-sample analyses validate the results. The findings not only highlight the importance of internal R&D efforts but also suggest that firms had better use ITL as a complement rather than a substitute of internal R&D for their competence.  相似文献

The Launch strategy for innovative products is a crucial strategic typology adopted by many high tech firms, and which has been identified in prior research focusing on new product introduction to the market. However, the nexus between launch strategies and firm resources has gained little research attention. This article therefore aims to investigate the influence of technological capability and social capital, two key resources for innovation in high tech firms, on the adoption of a launch strategy for innovative products. Furthermore, prior research has revealed that market characteristics play a moderating role on the relationship between firm resources and company strategies; thus, this study also examines the moderating effect of market characteristics. This study takes Taiwan's integrated circuit design firms as the analytical sample. Based on a sample of ninety companies, two interesting findings have been found. First, both technological capability and social capital are associated positively with the launch strategy for innovative products. Second, while the market growth rates increase, the positive relationship between technological capability and the launch strategy for innovative products becomes weaker.  相似文献

In this paper, we first propose a multi-dimensional Bühlmann credibility approach to forecasting mortality rates for multiple populations, and then compare forecasting performances among the proposed approach, the CBD model, the Lee-Carter model (LC), the joint-k (JoK-LC), the co-integrated (CoI-LC), and the augmented common factor (ACF-LC) Lee-Carter models for multiple populations. Mortality data from the Human Mortality Database are fitted to the underlying mortality models for both genders of three well-developed countries (the US, the UK, and Japan) and both genders of a developed country (France) and a developing country (Poland) with an age span 25–84 and a wide range of fitting year spans. Empirical illustrations show that the proposed multi-dimensional Bühlmann credibility approach contributes to more accurate forecast results, measured by AMAPE (average of mean absolute percentage errors over all fitting year spans), than the CBD, LC, JoK-LC, CoI-LC and ACF-LC models for three forecasting year spans 2004–2013 (10-year wide), 1994–2013 (20-year wide) and 1984–2013 (30-year wide).  相似文献

In this paper, we apply the threshold cointegration model of Hansen and Seo (2002), incorporating differences in the nonlinear behavior of investors across regimes. An examination of the trading behavior of foreign, domestic institutional, and domestic individual investors in Taiwan revealed no predominance among the three types of investors. When the market was near equilibrium, the purchases of domestic individual investors positively impacted stock prices. This finding, which is consistent with Choe et al. (2005), suggests that domestic individual investors have an edge in investment performance over other types of investors. However, when the market departed substantially from equilibrium, the purchases of foreign and domestic institutional investors predicted a rise in stock prices. On the other hand, domestic individuals traded at worse stock prices; these prices tended to fall (rise) after the purchase (sale).  相似文献

This paper analyzes the relationship between interest-rate feedback rules and macroeconomic stability in the presence of transaction costs. We show that with the Sims-type (1994) transaction-cost technology, a passive, rather than an active, interest-rate rule is more likely to generate a stabilizing effect against belief-driven fluctuations if both the intertemporal elasticity of substitution with respect to consumption and the sensitivity of the transaction costs with respect to the velocity of money are low. This result is valid under either an unbounded or a bounded transaction-cost technology. Of importance, our result is relevant under empirically plausible parameters, while it sharply contrasts with Taylor's (1993) prediction.  相似文献

The study investigated the effects of profit sharing (cash-based, stock-based and combined-total profit sharing) on organizational citizenship behaviour (OCB). It also examined the mediating role of organizational commitment on the relationship between profit sharing and OCB. Data were collected from 426 employees of 35 information electronics companies in Taiwan. Results showed that whereas cash-based profit sharing had no effect on OCB, both combined-total profit sharing and stock-based profit sharing positively influenced OCB. We also found that organizational commitment mediated the relationship between profit sharing (stock-based and combined-total profit sharing) and OCB.  相似文献

中国乡村公共品的提供:连带团体的作用   总被引:2,自引:0,他引:2  
在威权和转轨体制下,民主和官僚政治制度通常很薄弱,为什么处于这种制度下的政府官员所提供的公共品,往往还超过了足够维护社会稳定所需的最低水平呢?案例研究表明,即使正式责任制度很薄弱,非官方惯例和规则的约束仍然能够促使当地官员设立并履行其公共责任。而这些非正式责任制度由特定类型的连带团体提供并在全社区发挥其道德权威。在其他条件都相同的情况下,存在这类集团的村庄比没有这类集团的村庄更有可能获得较好的公共品供应。  相似文献

We build a model of international subcontracting in quality‐differentiated goods. Assuming no entry in an original equipment manufacturing (OEM) market, we show that the foreign outsourcer will choose an original design manufacturing (ODM) contract only if the subcontractor is good enough at product design. However, the product quality with the ODM contract is not necessarily higher than that with the OEM contract. When the subcontracting market becomes perfectly competitive, the outsourcer will always choose an OEM contract. In a two‐period model with learning and entry effects, the foreign outsourcer chooses between different modes of manufacturing contracts. We demonstrate that a laissez‐faire policy on research and development (R&D) activity may be optimal even if the subcontracting firm can only obtain an OEM contract. In the case where the OEM market becomes perfectly competitive in the second period, we predict that a positive R&D subsidy in the first period can help the domestic subcontractor obtain OEM–ODM contracts and, as a result, national welfare rises.  相似文献
