Propensity to firm creation: empirical research using structural equations   总被引:2,自引:0,他引:2  
The identification of the entrepreneurs’ characteristics and the knowledge of the entrepreneurial profile of university students have been assuming a growing importance in the development of educational programs directed towards the entrepreneurship and start-up processes. This study aims to identify the factors that most contribute for the intention to start up a business. The research also tries to identify the profile of a potential entrepreneur student concerning several characteristics: personal attributes, family, demographic variables and motivations. Research findings include the idea that entrepreneurship education is the most relevant factor in what concerns the propensity to business creation. On the other side, personal characteristics have an important role in shaping motivation to start-up a business and perceived hurdles have a negative impact in the intention to start-up. The results may be relevant when developing an adequate educational program directed to the entrepreneurship education and start-up processes.  相似文献

The paper investigates implications of different theoretical models for hierarchical structure. A sample of 6,578 firms in the Brazilian manufacturing industry is considered and explanatory factors pertaining to structural characteristics, network technology, technological innovations, managerial innovations and incentive mechanisms are investigated. Important joint effects are detected for all groups of variables in partial contrast with the related previous literature. Moreover, one detects significant joint effect of the newly considered group of incentive variables. The evidence in terms of individual effects is largely consistent with the predicted effects from the theoretical literature.  相似文献

Recent decades have seen a fundamental shift in the nature of economic regulation in the United States. Unauthorized by congress, and largely unnoted in legal and academic circles, regulatory agencies such as the Federal Communications Commission have changed the regulatory process by linking otherwise unrelated regulatory issues. Examples include tying merger approval to firm commitments to engage in conceptually unrelated build‐outs and other projects of political importance. This linking of issues has several effects, the most prominent being (a) tying regulatory issues changes the outcomes obtained, plausibly in predictable ways; (b) tying in some circumstances allows regulators to extend their authority to issues for which they have little or no legal authority; and (c) tied regulatory bargaining fails to produce valid legal precedent for firm decision making. We provide an analysis of these conclusions by examining the increasing use of consent decrees, voluntary merger commitments, and merger conditions by the Federal Communications Commission, referencing our discussion with a simple model of joint bargaining applicable to regulatory practice.  相似文献

This article considers the outsourcing choice of a downstream firm with its own upstream production resources or assets. The novelty of the approach is to consider the outsourced function as involving resources consistent with the resource‐based view of the firm. From a bargaining perspective, we characterize a downstream firm's decision whether to outsource to an independent or to an established upstream firm. In so doing, the downstream firm faces a trade‐off between lower input costs afforded by independent competition, and higher resource value associated with those who can consolidate upstream capabilities. We show that this trade‐off is resolved in favor of outsourcing to an established firm. Copyright © 2008 John Wiley & Sons, Ltd.  相似文献

This study explores the influence that entrepreneurial cognition, in terms of the dichotomy in human information processing, has on the earliness of internationalization and post-entry speed. Entrepreneurial cognition is investigated through the lens of the dual-process theory, which posits that human information processing is formed of two systems, the experiential cognitive system (System 1) and the rational and analytical cognitive system (System 2). The speed of the entire internationalization process is analyzed in terms of earliness (how soon after inception a company enters its first international market) and post-entry speed (how fast it enters new markets after the first internationalization). Drawing on ten cases, we find that companies that internationalized earlier and faster were managed by entrepreneurs with higher levels of the experiential cognitive system. In contrast, companies that internationalized later and more gradually were managed by entrepreneurs with higher levels of the rational cognitive system. Thus, our study reveals that the speed of the entire process of internationalization is governed, at least partially, by the entrepreneur’s cognition. On the basis of our findings, we introduce three propositions on the moderation that the entrepreneur’s cognition exerts on the well-established relations between environmental signals and both earliness of internationalization and post-internationalization speed.

As China is becoming an important market and there are a lot of foreign ventures operating there, different lines of research have been providing useful information for foreign ventures to manage effectively in China. In this paper, we discuss one of the critical factors leading to successful management of Chinese subordinates, i.e. building and maintaining good guanxi (i.e., interpersonal connection) with them. We conducted an empirical investigation to illustrate (1) the supervisor-subordinate guanxi concept is different and unique when compared to other similar concepts in the Western literature such as leader-member exchange (LMX) and commitment to supervisor; (2) the supervisor-subordinate guanxi will affect the Chinese supervisor's administrative decisions; (3) guanxi can be measured by concrete behaviour/activities. Data on 189 supervisor-subordinate dyads were collected in the People's Republic of China (PRC). Results indicated that supervisor-subordinate guanxi is a distinct concept from LMX and commitment to supervisor. It also has additional explanatory power over supervisory decisions on promotion and bonus allocation after controlling for performance. Implications for foreign ventures and expatriates are discussed.  相似文献

MIDZUNO'S sampling procedure is considered where the first (n – 1) draws are carried out with simple random sampling without replacement and the nth draw with varying probabilities. It is shown that for this scheme, the best estimator in the HORVITZ–THOMPSON (1952) Tt–class of linear estimators exists and rejects the last draw. When MURTHY'S technique of unordering of an ordered estimator is employed, the rejected draw is restored and the unordered estimator is obtained. Surprisingly, this unordered estimator is the same as the unordered best estimator in the T1–class, derived for IKEDA–SEN'S sampling procedure.  相似文献
