This study attempts to apply real options and expand the model designed by Lin and Huang [Lin, T.T., Huang, Y.T.: J. Technol. Manage. 8(3), 59–78 (2003)], which helps venture capital (VC) companies to optimize project exit decisions. The expected discounted factor and a jump-diffusion process combine to assess the value of a start-up company, and determine the threshold of the exit timing of liquidation or convertibility for establishing the optimal disinvestment evaluation model for VC companies. When the project value is below VL*V_L^\ast, the VC company carries out liquidation, but when the project value exceeds VC*V_C^\ast, the VC company performs convertibility. The project value is ranging between (VL *,VC*)\left({V_L ^\ast,V_C^\ast}\right), and the best choice is holding the decision and waiting to carry out the rights of liquidation and convertibility next time. Besides, this work attempts to identify the expected discounted time in terms of the investment time for VC companies.  相似文献

Latent variable models (LVMs) offer one route to examine the quality of data collected in surveys. The possibility exists that individuals equivalent in their true level of a construct or variable being measured are unlikely to have equivalent observed responses as a function of an extraneous variable, e.g., group membership. This potential is labeled here as differential item functioning (DIF). Survey methods generally considers measurement bias to be estimators that do no not accurately reflect true values. DIF may be thought of as differential measurement bias, i.e., measurement bias conditional on group membership. As a function of group membership, the degree, amount, or type of measurement bias changes. DIF has the potential to negatively affect the quality of data. LVMs, e.g., confirmatory factor analysis (CFA), offer one tool to assess DIF. However, few published examples exist in the survey research field and training in the interpretation of these models is lacking. The purpose of the current paper is to describe CFA sufficiently for interpretive purposes and demonstrate an empirical application of CFA to assess survey data quality to provide further interpretive guidance. References are provided for analysts wishing to conduct analyses of this type.  相似文献

The world’s nations often produce commodities for which they have no apparent comparative advantage, and do so with techniques that are not particularly efficient by world standards. These inefficiencies may arise from various forms of trade and domestic distortions, as described in Chau et al., Int Econ Rev 44:1079–1095, (2003). We estimate these distortions for 33 countries of the world using a newly compiled data set. We find that domestic distortions tend to be slightly more important than trade distortions. For the average country, revenues in the agricultural sector would be 26% higher if domestic distortions were eliminated, but 21% higher if trade distortions were eliminated. Our measures of trade and domestic distortions across countries provide a complement to measures of protectionism such as producer subsidy equivalents.  相似文献

Pearn et al. (Commun. Stat. Theory Methods, 27(4):985–1000, 1998) introduced the process accuracy index C a to measure the degree of process centering, the ability to cluster around the center. In this paper, we derive an explicit form of the cumulative distribution function for the estimator [^(C)]a{\hat{C}_a } with the case of symmetric tolerances. Subsequently, the distributional and inferential properties of the estimated process accuracy index C a are provided. Calculations of the critical values, P-values, and lower confidence bounds are developed for testing process accuracy. Further, a generalization of C a for the case with asymmetric tolerances is proposed to measure the process accuracy. Based on the results practitioners can easily perform the testing of the process accuracy, and make reliable decisions on whether actions should be taken to improve the process quality. An application is given to illustrate how we test the process accuracy using the actual data collected from the factory.  相似文献

Unlike Parmet’s (2005) well-written and thoroughly researched biography and many other generally admiring books and articles on David Dubinsky, the former International Ladies’ Garment Workers’ Union (ILGWU) president from 1932 to 1966, this essay contends that even though Dubinsky initiated important developments within the ILGWU and fought heroically against Nazism and Fascism, his right-wing social democratic worldview was ultimately divisive to the achievement of national and international working class unity. Dubinsky’s political positions become evident through his vigorous anti-Communism which he engaged in with regards to his dealings with Communists in the ILGWU, the Congress of Industrial Organizations, and the American Labor Party. Moreover, the exporting of his anti-Communism abroad via the American Federation of Labor’s Free Trade Union Committee and the International Confederation of Free Trade Unions damaged international working class unity through the sabotaging of radical trade unionism not only in Western Europe but in nations around the globe. Understanding Dubinsky’s anti-Communism is the key for ultimately comprehending the garment union leader’s politics.  相似文献

The aim of the present study was to evaluate the outcome of sexual harassment policy in the Dutch Police Force. Using a survey, sexual harassment was measured in 2000 and again in 2006 and we tested whether sexual harassment is associated with the comprehensiveness of policies. To be able to identify divisions with comprehensive policies, we interviewed 29 key persons in semi-structured interviews. It appeared that between 2000 and 2006 sexual harassment did not decrease: neither for women nor for men. Furthermore, the risk of sexual harassment was not lower in divisions that implemented comprehensive policies than in divisions with less comprehensive policies. The results suggest that sexual harassment is a workplace hazard that is very difficult to prevent in male dominated workplaces and implementing a comprehensive policy is not sufficient to prevent this workplace hazard.  相似文献

Over recent years, parental leave policy in Canada has evolved quite considerably. Since 2001, Canadian employees have a right to a 1 year paid parental leave; those in the province of Québec have a better paid, more flexible regime. This paper first shows that Québec is somewhat of an exception in the North American context, with its inclusive mode of governance which contributes to positive policies in terms of family and childcare. This is due to a few elements: the recognition of a declining birthrate, but more importantly the significant involvement and actions of women’s advocacy organizations, in the context of an inclusive governance of family policy. We will defend the hypothesis that Québec has adopted a cumulative (or work–family balance) model in the field of work–family relation, while the US and English Canada tend to still resort mainly to a laissez-faire attitude, which to this day has limited employee rights in terms of parental leave, but also in terms of child care.  相似文献

We examine the stock recommendations of Jim Cramer televised on CNBC’s Mad Money, and document significant market reactions (i.e., announcement returns and volume) to Cramer’s recommendations, particularly for small capitalization stocks. The following findings indicate that the announcement returns are primarily due to price pressure from uninformed trading as opposed to the recommendations providing new value related information: announcement returns reverse following buy recommendations; bid-ask spreads temporarily decline; and there is no evidence of positive longer-term abnormal returns. One implication, when considered in combination with other works, is that investors should be cautious in following stock recommendations announced in the mass-media.  相似文献

Firms build business relationships during economic activities. The goal of this paper is to clarify production mechanisms and economic functions by identifying characteristic patterns of inter-firm interactions. In this paper, we empirically analyze an inter-firm network consisting of about one million firms and four million directed links, in order to specify network motifs, which are small subgraphs that occur more frequently than expected in a randomly generated network. We found that V-shaped triads are network motifs, while feedforward and feedback loop are anti-motifs. By defining roles in the subgraph according to structural equivalence, we also detected the significance profile of roles characterizing the industry sector. The taxonomy of industries obtained from the profiles is economically meaningful. These empirical findings may serve to provide an easily interpretable view of the entire inter-firm network and to improve the efficiency and safety of economic systems.  相似文献
