Resource‐based theory maintains that intrinsic characteristics of resources and capabilities, such as their tacitness, complexity, and specificity, prevent imitation and thereby prolong exceptional performance. There is little direct evidence to verify these claims, yet a substantial literature encourages firms to formulate competitive strategies around resources with these attributes. Further, work outside the resource‐based tradition suggests that these attributes can slow innovation, and it is not clear when this effect outweighs the benefits of inimitability. This paper seeks to clarify whether and how the complexity, tacitness, and specificity of a firm's knowledge affect the persistence of its performance advantages. We find that the complexity and tacitness of technological knowledge are useful for defending a firm's major product improvements from imitation, but not for protecting its minor improvements. The design specificity of technological knowledge delayed imitation of minor improvements in this study. Copyright © 2002 John Wiley & Sons, Ltd.  相似文献

Cross entropy is used to estimate the Almost Ideal Demand System for consumption in Greece. The entropy estimates are found to improve upon the SUR estimates. It is recommended that practitioners consider employing entropy based procedures in systems where the data set is small, where there are a large number of parameters, or where the data are deficient.  相似文献

We examine how an auditor's ability to terminate a multi-period client relationship provides the auditor with a real option whose value depends on the nature of informational asymmetry between the incumbent and other potential auditors. In particular, we isolate conditions under which the auditor's private and public sources of information behave as complements rather than substitutes. In such circumstances, increasing the likelihood of publicly provided information induces the auditor to expend more (rather than less)resources in private information gathering activities.  相似文献

Form, function, and finance: architecture and finance theory   总被引:1,自引:0,他引:1  
At least at first glance, a bank’s customers ought to be concerned with only one thing—the price they must pay for the services they receive. Architecture beyond the merely functional ought to have no role, especially not in the modern global economy in which increasingly automated financial intermediation of all sorts appears to be approaching the ideals of pure competition and perfect efficiency. Even in these financially sophisticated times, however, symbols matter, and the message communicated by these symbols is one which cannot be communicated in any other way. It is necessary for a financial institution, and perhaps even the financial system itself, to have a strong visual presence. There is a visceral appeal of an architecturally distinguished building to the senses that speaks to us in a way that the cerebral appeal of pure information cannot.  相似文献

An econometric model is used to measure the impact of the Three-Party Programme on European demand for U.S. orange juice. The results show that the programme has helped expand the demand for orange juice in European countries and, from the viewpoint of the U.S. citrus industry, is an economically preferred way of generating additional exports compared with using price reductions to achieve additional sales.  相似文献

Models with a premium on external finance produce counterfactual predictions about liquidity management. We address this shortcoming by introducing a fixed cost of increasing external finance into an otherwise standard investment/financing problem. This additional financial friction is well-motivated by case studies and our analysis shows that it generates more realistic predictions about liquidity management: firms hold external finance and idle cash simultaneously, and may invest an additional dollar of cash flow in liquidity rather than repaying external funds or investing in productive capital. In addition to better fitting the stylized facts about the time-series and cross-sectional pattern of liquidity holding, these results may help shed light on the fragility of estimates of investment–cash flow sensitivities.  相似文献

This paper analyses the cost of capital of firms with foreign equity listings. Our purpose is to shed light on the question whether international and domestic asset pricing models yield a different estimate of the cost of capital for cross‐listed stocks. We distinguish between (i) the multifactor ICAPM of Solnik (1979) and Sercu (1980) including both the global market portfolio and exchange rate risk premia and (ii) the single factor domestic CAPM. We test for the significance of the cost of capital differential in a sample of 336 cross‐listed stocks from nine countries in the period 1980–99. Our hypothesis is that the cost of capital differential is substantial for firms with international listings, as these are often large multinationals with a strong international orientation. We find that the asset pricing models yield a significantly different estimate of the cost of capital for only 12% of the cross‐listed companies. The size of the cost of capital differential is around 50 basis points for the US, 80 basis points for the UK and 100 basis points for France.  相似文献
