This research examines the impact of the firm's product innovation strategy on performance results. A total of 19 strategy dimensions were uncovered, which capture the specific elements of firms innovation strategies. Three dimensions of performance, independent of each other, were also identified and were found to be closely linked to the strategy adopted. For a high-impact new product program, an aggressive strategy emphasizing sophisticated technologies, heavy R&D spending, and a focused program was found appropriate. In contrast, a conservative strategy featuring avoidance of new markets and new product classes and a close synergy with the firm's technological resources resulted in a high success rate program. Finally, a high overall performance was the outcome of a balanced strategy: technologically aggressive, market oriented, and synergistic.  相似文献

The liquidity of securities—the relationship between volume of trading and changes in market price—has won increasing recognition as an element of investment strategy in recent years. Relatively high liquidity is deemed to be a desirable characteristic of a stock, especially for the institutional investor, who typically trades in large volume. Thus, firms can generally be expected to seek means of enhancing the liquidity of their shares. One of the supposed means of accomplishing this is by listing one's stock on a national securities exchange. This paper examines the relationship of common stock liquidity to both exchange listing and price behavior during major up and down movements in the market. Our conceptual and empirical analyses indicate that liquidity is linked to price behavior; and we suggest that the view held by at least some corporate officers—that exchange listing increases liquidity—may be erroneous. More specifically, it appears that when the amount of firm capitalization is taken into account, exchange listing does not result in greater stock liquidity.  相似文献

This paper investigates the death of firms and seizes a long-term perspective. It investigates the life spans of nearly 2,200 firms in seven birth cohorts of Swedish joint-stock companies, founded during seven separate years between 1899 and 1950. Research has traditionally emphasized individual- and micro-oriented factors in explaining post-entry performance, or has often focused on the influence of firm-specific structural factors (firm age and size). A less attended field recognizes environmental forces. This paper focuses on the interaction between the micro and macro levels, and combines structural and environmental factors. Employing a cohort approach, it relates firm survival to firm age and size, as well as to the effect of cohort affiliation and environmental change over time (period effects). During macroeconomic expansion, the risk of death decreases. Cohort effects are also evident. Firms founded during times of economic crisis exhibit lower survival rates. Consequently, cohort affiliation and environmental forces, i.e. period effects, can explain differences in death rates in different firm populations.

Within the past few years, executives have come under increased scrutiny and criticism for the levels of compensation they receive. At the same time, corporate practices surrounding the design and review of executive compensation programs have received increased attention. While some recent executive misconduct has involved violations of the law, many academics and other corporate critics view the issues involving executive compensation more from an ethical than a legal perspective. Several dimensions of the executive compensation decision process offer significant opportunities for ethical choices. This article identifies the major components of executive compensation and highlights decision points in the design and administration of each component where ethical issues may arise. Proposals to reduce the potential for ethical misconduct are also offered.  相似文献

Researchers embarking on their first international mail survey find very little guidance in the present academic literature. In 1988, two articles were published in the fall issue of the Journal of International Business Studies that claimed that: “at the moment the crossnational researcher has very little evidence upon which to base his judgments about [mail] survey design” [Jobber and Saunders (1988) An experimental investigation into cross-national mail survey response rates, Journal of International Business Studies19, 488] and “Literature concerned with response rates from industrial samples drawn from multiple countries is nearly absent” [Dawson and Dickinson (1988) Conducting international mail surveys: the effect of incentives on response rates within an industrial population, Journal of International Business Studies19, 492]. Unfortunately, not much has changed since. Still, very little is known about how respondents from different countries react to mail surveys. This article intends to fill part of this gap by describing the results of a large scale international mail survey in 22 countries. Response rates are shown to vary considerably across countries in a way that contradicts much of the earlier (American) research on this subject. Several explanations for these differences in response rates are put forward.  相似文献

江浙沪三省市外商直接投资与环境污染的因果关系检验   总被引:22,自引:0,他引:22  
文章利用1986-2003年江浙沪三省市实际利用外资额和废气排放量的数据进行了外商直接投资增长与环境污染加剧的因果关系检验,结果表明:在汇总的三省市数据和上海、江苏两省市的单独检验中,外商直接投资增长与环境污染加剧之间的因果关系较为明显;但是对于浙江省,这两者数据间的因果关系并不明显。建议今后一段时期内,长三角地区利用外资不仅要注重量的增加,更要注重质的提升,尤其是要提高外资利用的水平和效率,以缓解日益紧张的环境污染压力。  相似文献
