专利投机行为是专利运用的异化,其实施主体是被称为专利许可公司(NPEs)的非专利实施企业。从实施主体、专利类型、专利质量、许可关系及行为方式等要素系统解构专利许可公司的商业模式。在对专利投机行为盛行缘由和负面效应进行分析的基础上,运用NTP V. RIM和诺转型基亚两个经典案例,结合创新理论深刻揭示了专利许可公司的运营之道。  相似文献

引水工程是解决水资源空间分布不均匀的重要手段,是基础建设的重要组成部分,但引水工程在建设以及运营期间具有诸多不确定性,利用传统的投资决策模型无法充分考虑项目的不确定性,直接影响投资决策的可靠性和科学性.针对这一问题,本文提出一种基于模糊经济计算的引水工程投资决策方法,在工程经济基本模糊计算的基础上,构建基于模糊经济计算的引水工程投资决策模型,利用模糊数充分描述项目的不确定性.并通过实例计算,验证了该模型的适用性和有效性,提高了决策的科学性和准确性,对于项目规避风险也有很高的指导价值.  相似文献

Mitigating response distortion in answers to sensitive questions is an important issue for business ethics researchers. Sensitive questions may be asked in surveys related to business ethics, and respondents may intend to avoid exposing sensitive aspects of their character by answering such questions dishonestly, resulting in response distortion. Previous studies have provided evidence that a surveying procedure called the randomized response technique (RRT) is useful for mitigating such distortion. However, previous studies have mainly applied the RRT to individual dichotomous questions (e.g., yes/no questions) in face-to-face survey settings. In this study, we focus on behavioral research examining the relationships between latent variables, which are unobserved variables measured by multiple items on Likert or bipolar scales. To demonstrate how the RRT can be applied to obtain valid answers from respondents answering a self-administered online questionnaire with Likert and bipolar scales, we build a behavioral model to study the effect of punishment severity on employees’ attitudes toward misuse of information systems resources in the workplace, which in turn influence misuse behavior. The survey findings meet our expectations. The respondents are generally more willing to disclose sensitive data about their attitudes and actual behavior related to misuse when the RRT is implemented. The RRT’s implications for causal modeling and the advantages and challenges of its use in online environments are also discussed.  相似文献

In Malaysia, the participation of women in the labor market has increased over time. However, occupational segregation and wage differentials continue to be prevalent between men and women in the labor market. The present paper investigates gender‐related occupational segregation and wage differentials based on data collected from 7135 working households in Peninsular Malaysia in 2011. The wage decomposition model introduced by Brown et al. (1980) is used to examine the determinants of gender‐related wage differentials. The results suggest that differences within occupations account for the largest portion of the wage gap between men and women. The results also indicate that wage discrimination within occupations plays an important role in the gender wage gap, while sample selection bias plays an important role in the examination of gender wage gaps.  相似文献

We investigate how foreign debt and foreign direct investment (FDI) affect the growth and welfare of a stochastically growing small open economy. First, we find that foreign debt influences the growth of domestic wealth by lowering the cost of capital, while FDI affects the country's welfare by providing an additional source of permanent income. Second, a decline in domestic investment may improve domestic welfare as FDI replaces the gap. Even when the welfare deteriorates, its magnitude is mitigated, leaving more room for discretionary fiscal policy. Third, a fiscal policy aimed to stabilize domestic output fluctuations needs to be conducted not to crowd out the welfare benefit of FDI too much. Fourth, an economy with both types of foreign capital experiences wider welfare swings by external volatility shocks than the one with foreign debt alone, while the welfare effects from domestic volatility shocks are mitigated. The welfare effects of fiscal shocks are much smaller with both types of foreign capital. Lastly, the first-best labor income tax covers the government absorption by the labor's share of total output, and the capital income tax covers the rest. Investment is penalized or subsidized depending on the social marginal cost-gain differential.  相似文献

This study solves a location‐then‐price game in which horizontal and vertical differentiation are combined using an asymmetric distribution of consumers’ taste. Boundary locations are robust when the taste disparity of the population is not large and out‐of‐market locations are not allowed. Firms may have incentives to move either inside or outside the market in other situations, so the equilibrium prices are never differentiated. The restrictions of vertical differentiation under this framework are further examined. A model with the entrance of a vertically differentiated product is also discussed.  相似文献

This study explores when wholly owned subsidiaries outperform joint ventures with local partners. In order to avoid the endogeneity problem inherent in foreign subsidiaries' operating mode decisions that might confound performance measurement, we employ the propensity score matching method, along with the difference‐in‐differences approach, and compare the performances of joint ventures turned wholly owned subsidiaries vis‐à‐vis continuing joint ventures. Based on foreign subsidiaries' financial data in China for 1998–2006, we find strong evidence that converted wholly owned subsidiaries outperform continuing joint ventures in industries characterized by high levels of intangible assets such as technology or brand, after controlling for factors that may affect the conversion decision. This finding is consistent with the prediction of transaction cost theory. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

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

Outward direct investment (ODI) and domestic R&D are interrelated, but empirical evidence is affected by the nature of a firm's data, which are heavily censored. Firm data contain a firm's yes/no decision to invest in China, yes/no decision of R&D, and the decision of R&D intensity. We thus adopt a two-hurdle model and allow the China investment decision to be endogenous in an R&D model in order to examine the effect of ODI in China on domestic R&D investment in Taiwan's electronics industry. In the model, a two-equation simultaneous subsystem is formed, in which three regression equations are specified: a decision of R&D intensity, and a yes/no decision of location to conduct R&D together with a yes/no decision to invest in China Our results indicate that China investment and R&D intensity are positively related such that ODI in China helps to raise significantly a firm's R&D intensity as compared to the estimate if the endogeneity of China investment and the nature of data were not properly accounted.  相似文献
