Suppose a production function, f, is continuous, quasi-concave and weakly monotone on the non-negative orthant of Euclidean n-space. Let c(·, ·) be the associated cost function. Then it is shown that f is concave if and only if for each w, c(w, ·) is convex. 相似文献

Innovation requires the entrepreneurial capabilities of opportunity recognition and opportunity exploitation. Such capabilities generally accrue over time from a firm's cumulative learning and experience. In this study, we theorize that firm age should therefore moderate the firm's ability to leverage these capabilities for innovation activity, such that older firms can obtain higher outputs from their capabilities than younger firms can. We examine this relationship using a sample of 676 small and medium enterprises. We find that when both younger and older firms have highly developed innovation capabilities, older firms appear to enjoy higher levels of innovation activity than younger firms do. However, younger firms generally appear more likely to have higher levels of innovation activity than older firms do, when neither firm has highly developed innovation capabilities. We conclude with a discussion of the implications of these findings for research and practice. 相似文献

We find evidence that workforce educational diversity promotes entrepreneurial behavior of employees as well as the formation of new firms, whereas diversity in demographics hinders transitions to self-employment. Ethnic diversity favors entrepreneurship in financial and business services. 相似文献

Previous studies have generally established a positive relationship between aggregated measures of entrepreneurial orientation (EO) and firm performance. However, there are theoretical reasons suggesting that three dimensions of EO (innovativeness, proactiveness, and risk-taking) may possess differential relationships with performance in smaller firms. This study utilizes a sample consisting of 1,668 small-to-medium sized enterprises (SMEs) in nine countries across 13 different industries to provide a finer-grained analysis of the EO-performance relationship. Specifically, we theorize and test a non-monotonic influence of innovativeness, proactiveness, and risk-taking on SME performance. Innovativeness and proactiveness displayed predominantly positive U-shaped relationships with SME performance. Risk-taking, however, displayed a predominantly negative U-shaped relationship with SME performance. Further, individualism was found to positively moderate the relationships between innovativeness-performance and proactiveness-performance. Taken together, these results suggest that differential relationships exist between three dimensions of EO and SME performance, with important theoretical implications for future EO research. 相似文献

The paper explores the different patterns of labour relations in European companies. It is based on comparative research carried out in fifteen companies in Italy, France, Germany, Great Britain and Spain. 1 In each country, three companies in the chemical, food-processing and engineering industries have been studied, through interviews with the company management as well as with workers' representatives. The starting point is the observation that employers' policies of Jabour relations are today more differentiated than in the recent past: while many employers tend to involve unions in the re-organization of work, have frequent meetings with them and grant them full recognition, others pursue more unilateral paths to industrial adjustment and others still adopt a mixed policy of union involvement on some issues or for some categories of workers and of individual bargaining on others. An analysis of the major differences among the companies studied is then developed by illustrating three types of choices that managers have to make. The first concerns the extension of the involvement of workers' representatives in decisions. The second has to do with the use of direct relationships with individual workers, as an attempt to bypass the unions or simply as a new method to increase the overall information and communication. The third alternative regards the degree of homogeneity in the management of human resources, in which some rules and advantages may apply to either the whole labour force or some professional (and possibly age or gender) groups only. In the final section, some possible determinants of the differences in employers' strategies of labour regulation between firms and countries are examined. Special attention is paid to two institutional factors: the role of legal rights to information, consultation and negotiation in different national contexts, and the type of workers' representatives which are present in the companies. 相似文献

Brand activism is a new and fragmented phenomenon that has been attracting growing attention from scholars. Research on this topic is still at an exploratory stage and in need of advancement and conceptualization. The aim of this study is to systematize the extant literature on brand activism by attempting an in-depth exploration of the antecedents that identify the construct along with the influencing and consequence factors that will need to be tested and validated by future research. This study adopts the guidelines provided by the SPAR-4-SLR protocol and considers 76 papers with no time limitation. To the best of our knowledge, this seems to be the first scientific systematization of brand activism. From the in-depth analysis of the extant literature, two conceptual frameworks were constructed that can guide both researchers, in their understanding and investigation of the phenomenon, and practitioners in their implementation strategies of brand activism. The no time restriction of the analysis has allowed an investigation of the phenomenon from its prodromes until recent years, also highlighting important gaps that will have to be filled by future research. 相似文献

This paper considers a gradient method algorithm which locates a local optimum of an objective function on a constraint surface. The adjustment process is applied to the problem of searching for a Ramsey optimal price vector for a monopoly firm. 相似文献

Work‐related perks, such as corporate jets, nice offices, and so forth, improve the tradeoff between incentives and insurance that determines the optimal incentive contract. We show that (i) such perks may be offered even if their direct consumption benefits are offset by their costs; (ii) they will be offered for free; (iii) agents in more uncertain production environments will receive more perks; (iv) senior executives should receive more perks; and (v) better corporate governance can lead to more perk consumption by CEOs. Our analysis also offers insights into firms' decisions about how much autonomy they should grant to their employees. 相似文献
