Political entrepreneurship occurs when an individual acts on a political profit opportunity. These profit opportunities can be divided into two categories: productive, and predatory. Productive opportunities enable entrepreneurs to profit from enhancing the efficiency of government, while predatory opportunities enable entrepreneurs to profit from forcibly transferring resources from some to others. This analysis shows that political institutions tend to favor predatory over productive political entrepreneurship, and shows that what is sometimes referred to as political exchange does not have the same efficiency characteristics as voluntary exchange in private markets. 相似文献

We provide evidence on the impact of tax incentives and financial constraints on corporate R&D expenditure decisions. We contribute to extant research by comparing R&D expenditures in the United States and Canada, thereby exploiting the differences in the two countries' R&D tax credit mechanisms and generally accepted accounting principles. The two tax incentive mechanism designs are consistent with differing views of the degree of financial constraints faced by firms in these economies. Our sample also allows us to explore the effects of capitalizing R&D on Canadian firms. Employing a matched design, we document relations between tax credit incentives and R&D spending consistent with both Canadian and U.S. public companies responding as though they are not financially constrained. We estimate that the Canadian credit system induces, on average, $1.30 of additional R&D spending per dollar of taxes forgone while the U.S. system induces, on average, $2.96 of additional spending. We also find that firms that capitalize R&D costs in Canada spend, on average, 18 percent more on R&D. Collectively, this evidence is important to the ongoing debates in both countries concerning the appropriate design of incentives for R&D and is consistent with the assumptions found in the U.S. tax credit system, but not those found in the Canadian system. 相似文献

The purpose of this paper is to study how organizational rejuvenation is used to increase and support knowledge exploitation
in multinational enterprises. Using case-study data to explore the theoretical arguments, interesting findings emerge. The
main finding is that entrepreneurial activities in IT industry enable organizational rejuvenation with repercussions beyond
the focal function. Other findings relate to how corporate entrepreneurship activities provide possibilities for continuous
knowledge exploitation within the MNE and how entrepreneurial groups inside MNEs form the foundation from which the organizational
rejuvenation originates. Finally, the form of organizational rejuvenation studied embraced both structural and behavioral
changes.
The authors acknowledge an equal share in the development of this article. 相似文献

We investigate the investment decisions of Italian state-owned enterprises (SOEs) across budget constraint regimes and carry out a natural experiment that exploits a regime switch in 1987. Drawing on the theory of capital market imperfections, we apply an empirical framework for investment analysis to a panel of manufacturing SOEs in competitive industries. We identify parallels between SOEs and widely held, quoted companies afflicted by agency problems, managerial discretion, and overinvestment. We argue that, in the case of SOEs, the soft budget regime increases managerial discretion, facilitates collusion with vote-seeking politicians, and results in wasteful investment. Consistent with our predictions, we find that the regime switch disciplines SOE's investment behavior. Following a hardening of the budget constraint, managers lose discretion to indulge in collusion and overinvestment. J. Comp. Econ., June 2002 30(4), pp. 787–811.
