Although it is established that firms sometimes expand abroad to augment their capabilities, previous studies have generally focused on technological determinants of foreign expansion. We analyze capability‐seeking aspects of foreign direct investment by examining the relationship between upstream (technological) and downstream (marketing) capabilities and the choice between acquisition and greenfield modes of international entry. In analyzing 2175 entries by British, German, and Japanese investors into the United States, we find that for downstream capabilities, which tend not to be geographically fungible, the absolute level of capabilities in the entered industry explains the mode choice. However, for upstream capabilities, which tend to be geographically fungible, the acquisition motive stems from a relative capability differential between host and home country firms. These results have implications for the concept of fungibility in the resource‐based view of the firm as well as for the literature on sourcing of resident assets by foreign firms, which has thus far ignored issues of entry mode and downstream assets.

Two aspects of media bias are important empirically. First, bias is persistent: it does not seem to disappear even when the media is under scrutiny. Second, bias is conflicting: different people often perceive bias in the same media outlet to be of opposite signs. We build a model in which both empirical characteristics of bias are observed in equilibrium. The key assumptions are that the information contained in the facts about a news event may not always be fully verifiable, and consumers have heterogeneous prior views ("ideologies") about the news event. Based on these ingredients of the model, we build a location model with entry to characterize firms' reports in equilibrium, and the nature of bias. When a news item comprises only fully verifiable facts, firms report these as such, so that there is no bias and the market looks like any market for information . When a news item comprises information that is mostly nonverifiable, however, then consumers may care both about opinion and editorials, and a firm's report will contain both these aspects—in which case the market resembles any differentiated product market . Thus, the appearance of bias is a result of equilibrium product differentiation when some facts are nonverifiable. We use the model to address several questions, including the impact of competition on bias, the incentives to report unpopular news, and the impact of owner ideology on bias. In general, competition does not lead to a reduction in bias unless this is accompanied by an increase in verifiability or a smaller dispersion of prior beliefs.  相似文献

Research summary : Prior work has shown that the strength of the intellectual property regime (IPR) in a host country influences offshore R&D to that country. Building on this work we propose that the strength of the IPR in a host country differentially influences the threat of knowledge leakage on projects that are produced for the location where the multinational firm is headquartered (home) versus the offshore location to which the R&D project is sent (host). We argue and show that when the host location has a weak IPR, fewer host inventors are involved in host R&D projects when compared to home R&D projects. We test our hypotheses using a dataset of patents held by US assignees, but coinvented in 43 host locations with differing IPR strength. Managerial summary : Multinational enterprises often cite the weak IPRs at emerging economy host destinations as a significant impediment to offshore R&D activities in those countries, despite the abundant supply of inexpensive scientific talent there. We find that the weak IPR at the host destination is a greater impediment to offshore R&D that is aimed for end use at the host market than for R&D that is aimed for end use globally or in the home market. Since IPRs are local, a weaker IPR at the host location does not protect IP that is relevant to the host market. Since the IPR at the home country is more relevant for technologies aimed at the home market, the IPR at the host country is irrelevant for such R&D projects.

Conclusion This paper investigates the relation between mismatch and sectoral hiring functions. Traditionally, the indices used to measure structural mismatch were constructed by assuming that the hiring functions are identical across sectors. However, both theoretically and empirically, there is no reason to believe that the hiring behavior of the firms or the search methods of the workers are identical across sectors. Evidence for this is provided in the Appendix of this paper where it is shown that theUV curves for the different regions in Great Britain and different sectors in Switzerland are not identical. Brunello [1990] also shows that the hiring functions do not have to be identical. This paper also demonstrates that it may not be possible to eliminate structural unemployment totally when the hiring functions across sectors are non-identical. In other words, total hiring may be maximized even if theV/U ratios are not equalized across sectors. This conclusion is important as it highlights that the indices used in empirical work to measure structural mismatch may be seriously flawed.This paper develops an index for measuring mismatch which is rooted in the theory of hiring functions and utilizes the approach of measuring angle between vectors by the use of cos() functions. The FH index presented in this paper is based on a simple arithmetic mean of regional or sectoral cos() functions. It has been estimated for several European countries, and the empirical results highlight some interesting conclusions concerning regional mismatch in these countries.  相似文献

Group lending and individual lending with strategic default   总被引:2,自引:0,他引:2  
Papers that compare group lending and individual lending in the presence of strategic default suggest that unless group members can impose costly social sanctions on one another, or unless the bank uses cross-reporting mechanisms group lending may do worse than individual lending. In this paper, we show that if, (1) the amount that a successful borrower owes for his defaulting partner is optimally determined, and (2) the penalty is allowed to vary across group members, then even in the absence of any social sanctions or cross-reporting, (1) expected borrower welfare is strictly higher with group lending when both group lending and individual lending are feasible and (2) group lending is feasible for a greater range of opportunity cost of capital. These results are robust to collusion between borrowers.  相似文献

This article is an attempt to demonstrate how, in the absence of infrastructural requirements for development in the rural areas, the interpersonal relationships of women articulated through their households, kinship networks and community structures serve as indispensable mechanisms for their survival. These mechanisms are seen as part of an indigenous socio‐economic framework that is referred to here as the ‘economy of affection’. This framework is presented, through ethnographic data, as a means of facilitating moral, social and economic support among the indigent rural people in KwaZulu‐Natal. Taking cognisance of local organisational forms and resources is the best possible way to reconstruct South Africa's vast hinterland against the background of a history of development patterns, where rhetoric has played a more important role than actual substantive contributions to development of the rural poor, and where capital investments, technology and expertise of a post‐industrial nature are unlikely to spread.  相似文献

Despite the innate advantage founder CEOs have by virtue of their founding vision, organizational influence, positive image, and ownership stakes to lead their firms at their initial public offering (IPO), extant empirical evidence indicates that between a third to half of IPO firms go public with non-founder CEOs at the helm. Relatively little however, is known regarding factors that influence the choice of founder versus non-founder CEO for firms issuing IPOs. This study examines the impact of factors such as founder characteristics, size of founding team, governance structure, ownership structure, top management team independence, venture capitalist influence, and the demand for equity financing on the probability of founder CEO at IPO.  相似文献

Abstract:  We examine the impact of strategic investment choices at the time of the IPO on: (i) the post-issue operating performance and (ii) the likelihood of failure and time-to-failure of newly public US firms. Our post-issue operating performance analysis uses various performance metrics, benchmarks, and expectation models. Overall, our evidence indicates that the extent of diversification and industry-adjusted capital expenditures intensity are generally positively related to changes in operating performance. We do not, however, document a consistent relation between industry-adjusted R&D expenditures and changes in operating performance. The results from our survival analysis suggest that pre-issue managerial commitment to R&D spending and developing diversified product lines enhance the ability of IPO issuing firms to remain viable for longer periods of time. Our study highlights the impact of various managerial investment decisions on the subsequent performance of newly public firms.  相似文献
