The paper presents a simple model to study the effects of rumours on markets. Agents in our economy communicate with their local neighbours which gives rise to the possible spread of a rumour. As the rumour affects beliefs of the agents the evolution of the rumour has a direct impact on market outcomes. Our results show that if the rumour dies out long-run equilibrium prices correspond to pre-rumour values. However, if the rumour stays present it produces a price run-up for the good that is positively targeted by the rumour. Price run-ups related to rumours have been observed in empirical studies by Rose [Rose, A.M., 1951. Rumor in the stock market. Public Opinion Quarterly 15, 461–486], Pound and Zeckhauser [Pound, J., Zeckhauser, R., 1990. Clearly heard on the street: the effect of takeover rumors on stock prices. Journal of Business 63, 291–308] and Zivney et al. [Zivney, T., Bertin, W.J., Torabzadeh, K.M., 1996. Overreaction to take-over speculation. Quarterly Review of Economics and Finance 36, 89–115]. The present model provides an analytical foundation for this finding. 相似文献

The sluggishness of capital spending over the recovery has reinvigorated the debate over UK investment performance. It has frequently been alleged that the UK financial system holds back investment, while the institutions of continental European countries – particularly Germany – are more supportive of long-term spending by companies. In this article, Harold Rose examines the theoretical and factual basis for this line of argument. He warns policy-makers against acting to promote investment on the basis of arguments which are either not securely founded or which are directly contradicted by the evidence. 相似文献

AbstractThe speed at which contemporary fashion changes is such that the life of a garment can now be measured in a matter of weeks rather than months. The organisational consequences of operating in this environment are that fashion retailers have been prompted to adopt a range of quick response (QR) initiatives. QR involves responding promptly to the information contained within emerging sales trends while simultaneously accelerating the movement of product from factory to shop shelf. Drawing on the case of a UK fashion chain, this paper explores accounting's role in enacting QR. In addition, by deploying the theoretical framework of governmentality [Miller, P., & Rose, N. (1990). Governing economic life. Economy and Society, 19(1), 1–31; Rose, N., & Miller, P. (1992). Political power beyond the state: Problematics of government. British Journal of Sociology, 43(2), 173–205], the paper highlights the role of calculative technologies in the creation and sustenance of fast fashion and hence the governance of everyday dress. 相似文献

Professor Rose demonstrates how the Thatcher Government's progress is much closer to that of her Labour predecessor than is realised. His graphs demonstrate dramatically how much political courage will be required to prevent welfare spending and trade union obstructions to growth dragging Government policies into the same traps. 相似文献

The above article, published online on 24 February 2010 in Wiley Online Library ( www.wileyonlinelibrary.com ) has been retracted by agreement between Jacob Rose; the General Editor, Bill Harley; and John Wiley & Sons, Ltd. The institution of the first‐named author, Bentley University, has conducted investigations that find compelling evidence that Dr. Hunton fabricated data in two other studies without the knowledge of his coauthors. The data for this article were generated by Dr. Hunton, and he did not provide evidence to support the validity of these data upon request. Based on the lack of supporting evidence from Dr. Hunton, the validity of the data cannot be confirmed. The article has been retracted to correct the academic literature and maintain standards of academic integrity. REFERENCE Hunton, J. E. and Rose, J. M.
