This study examines the role of network knowledge resources in influencing firm performance. More specifically: Can a firm that uses the identical supplier network as competitors and purchases similar inputs from the same plants achieve a competitive advantage through that network? In a sample of U.S. automotive suppliers selling to both Toyota and U.S. automakers, we found that greater knowledge sharing on the part of Toyota resulted in a faster rate of learning within the suppliers' manufacturing operations devoted to Toyota. Indeed, from 1990 to 1996 suppliers reduced defects by 50 percent for Toyota vs. only 26 percent for their largest U.S. customer. The quality differences were found to persist within suppliers because the inter‐organizational routines and policies at GM, Ford, and Chrysler acted as barriers to knowledge transfers within suppliers' plants. These findings empirically demonstrate that network resources have a significant influence on firm performance. We also show that some firm resources and capabilities are relation‐specific and are not easily transferable (redeployable) to other buyers or networks. This result implies that a firm may be on its production possibility frontier for each customer but the productivity frontier will be different for each customer owing to constraints associated with the customer's network.

A ‘futurist’ is the generic term for someone seriously engaged in the consideration of future conditions. ‘Futures research’ has a systems science orientation with a planning horizon in excess of 10 years. ‘Futures studies’ has a social science connotation and ‘foresight’ is the most popular term within the management science and corporate sectors. Five schools of futures researchers are defined: 1. Environmental and geosciences. 2. Infrastructure systems and engineering technology. 3. Social, political and economic science. 4. Human life, mind and information science. 5. Business and management science. The academic route to a futures qualification is outlined with a list of futures orientated organisations. The inclusion of urbanisation in the next generation of scenarios for climate change research and assessment, would involve replacing the notion of economic equilibrium by the concept of far-from-equilibrium stability. Finally futures research is described as an evolutionary science, which will possibly become integrated within complexity science by 2050. 相似文献

A prominent motive for corporate venture capital (CVC) is the identification of entrepreneurial-firm acquisition opportunities. Consistent with this view, we find that one of every five startups purchased by 61 top corporate investors from 1987 through 2003 is a venture portfolio company of its acquirer. Surprisingly, our analysis reveals that takeovers of portfolio companies destroy significant value for shareholders of acquisitive CVC investors, even though these same investors are “good acquirers” of other entrepreneurial firms. We explore numerous explanations for these puzzling findings, which seem rooted in managerial overconfidence or agency problems at the program level. 相似文献

We extend the benchmark nonlinear deterministic volatility regression functions of Dumas et al. (1998) to provide a semi-parametric method where an enhancement of the implied parameter values is used in the parametric option pricing models. Besides volatility, skewness and kurtosis of the asset return distribution can also be enhanced. Empirical results, using closing prices of the S&P 500 index call options (in one day ahead out-of-sample pricing tests), strongly support our method that compares favorably with a model that admits stochastic volatility and random jumps. Moreover, it is found to be superior in various robustness tests. Our semi-parametric approach is an effective remedy to the curse of dimensionality presented in nonparametric estimation and its main advantage is that it delivers theoretically consistent option prices and hedging parameters. The economic significance of the approach is tested in terms of hedging, where the evaluation and estimation loss functions are aligned. 相似文献

We analyze the relation between antitakeover provisions (ATPs) and the performance of spin-off firms. We find that firms protected by more ATPs before spin-offs have higher abnormal announcement returns and greater improvements in post-spin-off operating performance than firms with fewer ATPs. Further, firms that reduce the number of ATPs after spin-offs have greater improvements in operating performance than firms that do not reduce the number of ATPs. Finally, CEOs of pre-spin-off firms tend to retain more ATPs in parent firms and assign fewer ATPs to the spun-off units if they remain as the CEOs of the parents but not the spun-off units. Overall, our results indicate a positive relation between ATPs and the value gains to spin-offs. 相似文献

The increasing unacceptability of the concept of entity law and the emergence of the doctrine of enterprise law with respect to many aspects of the legal relationships of parent and subsidiary corporations particularly in insolvent situations is a very interesting issue. This change is very significant because it reflects a growing unwillingness on the part of the courts and legislatures to continue accepting the traditional view of corporate law when it no longer corresponds to the economic reality of the modern business enterprise in a complex industrialized international society. This paper examines the American case law and in particular the decisions that have imposed liability where a company is liable for the obligations of an insolvent subsidiary and by contrast the decisions that have denied liability. The paper also examines the position in Argentina within the Argentine law and the UNCITRAL recommendations in respect of liability issues within corporate groups in insolvency.

Differences between yields on comparable‐maturity U.S. Treasury nominal and real debt, the so‐called breakeven inflation (BEI) rates, are widely used indicators of inflation expectations. However, better measures of inflation expectations could be obtained by subtracting inflation risk premiums (IRP) from the BEI rates. We provide such decompositions using an affine arbitrage‐free model of the term structure that captures the pricing of both nominal and real Treasury securities. Our empirical results suggest that long‐term inflation expectations have been well anchored over the past few years, and IRP, although volatile, have been close to zero on average. 相似文献

This article investigates the natural hedging strategy to deal with longevity risks for life insurance companies. We propose an immunization model that incorporates a stochastic mortality dynamic to calculate the optimal life insurance–annuity product mix ratio to hedge against longevity risks. We model the dynamic of the changes in future mortality using the well‐known Lee–Carter model and discuss the model risk issue by comparing the results between the Lee–Carter and Cairns–Blake–Dowd models. On the basis of the mortality experience and insurance products in the United States, we demonstrate that the proposed model can lead to an optimal product mix and effectively reduce longevity risks for life insurance companies. 相似文献

Newly public companies must disclose significant risk factors in the offering prospectus. These disclosures are examples of “soft” or ambiguous information. Ambiguity models predict that investors will alter their portfolio weights and react to subsequent signals about such information. We test for these effects in a sample of 1,398 initial public offerings (IPOs) using word count ratios between soft and hard information as measures of ambiguity. We find a significant relationship between the soft information on risk and both initial and ex post measures of returns. These results support the view that soft information embeds ambiguity and that it influences investors’ portfolio choices. 相似文献

Smallholder market participation under transactions costs: Maize supply and fertilizer demand in Kenya 总被引:1,自引:0,他引:1
This paper assessed the effects of transactions costs—relative to price and non-price factors—on smallholder marketed surplus and input use in Kenya. A selectivity model was used that accounts for the effects of transactions costs, assets, technology, and support services in promoting input use and generating a marketable surplus. Output supply and input demand responses to changes in transactions costs and price and non-price factors were estimated and decomposed into market entry and intensity. The results showed that while transactions costs indeed have significant negative effects on market participation, institutional innovations—such as group marketing—are also emerging to mitigate the costs of accessing markets. Output price has no effect on output market entry and only provides incentives for increased supply by sellers. On the other hand, both price and non-price factors have significant influence on adoption and intensity of input use. Overall, the findings suggest that policy options are available other than price policies to promote input use and marketed surplus. The paper concludes with implications for policy to induce greater input–output market participation among smallholders in Africa. 相似文献
