This paper seeks to analyse small‐ and medium‐sized enterprise (SME) managers' representations of corporate social responsibility (CSR) and CSR communication in a corporate communication perspective. The basic question is: how strategic is CSR communication in SMEs? Corporate communication and CSR theories are used to establish an ideal typology of CSR concepts informing an analysis of qualitative data in the form of interviews with three middle managers in two Danish SMEs. A CSR communication model published earlier by the authors is challenged from a SME perspective. Results from an Internet‐based questionnaire survey of 1071 SMEs pave the way for the analysis. Our analysis shows that SME managers clearly have an inside‐out approach to CSR, with a strong emphasis on the internal (corporate culture) dimension. However, SMEs and/or SME managers tend not to communicate externally about the CSR activities of the company. Based on these findings, the paper argues that CSR communication in SMEs is challenged by the global economy and is under revision. The contribution of the paper is to provide an insight into SMEs' present stage in relation to a possible future approach to strategic CSR communication. The paper also reminds us that SMEs have no interest in turning their local and authentic practice into a forced marketing and branding exercise, leaving them with an artificial picture of who they are and strive to be in the future. They should keep on acting locally but force themselves to think globally. 相似文献

This paper examines the conditions for fiscal restraint to emergeas Nash equilibrium in the game between fiscal authorities ina monetary union and discusses the implications for the ECB'smonetary strategy. We show that fiscal authorities fail to internalizethe adverse area-wide effects of their policies when the ECBtargets union-wide aggregates. To address this co-ordinationfailure, we propose that the ECB reacts to fiscal restraintby implementing a monetary reward. Applying the pareto- andrisk dominance criteria to the ensuing co-ordination game, weshow that the ECB can ensure convergence upon fiscal restraintby adopting a weakly countercyclical reaction function. 相似文献

Cover's celebrated theorem states that the long‐run yield of a properly chosen “universal” portfolio is almost as good as that of the best retrospectively chosen constant rebalanced portfolio. The “universality” refers to the fact that this result is model‐free, that is, not dependent on an underlying stochastic process. We extend Cover's theorem to the setting of stochastic portfolio theory: the market portfolio is taken as the numéraire, and the rebalancing rule need not be constant anymore but may depend on the current state of the stock market. By fixing a stochastic model of the stock market this model‐free result is complemented by a comparison with the numéraire portfolio. Roughly speaking, under appropriate assumptions the asymptotic growth rate coincides for the three approaches mentioned in the title of this paper. We present results in both discrete and continuous time. 相似文献

Exchange rate volatility and long-term distortions of exchange rate levels have given rise to concern among participants in international trade. Do exchange rate fluctuations have an adverse impact on the volume of trade? What measures could be taken to achieve greater exchange rate stability? 相似文献

This article analyses job mismatches in Switzerland based on a subjective measure of overqualification. According to job search and job matching theories, overqualification is a transitory problem. Other theories show that overqualification can also be of a permanent nature. We test the perpetuity of overeducation using panel data from the first eight waves of the Swiss Household Panel (SHP) covering the period 1999 to 2006. Our empirical analysis reveals little evidence for lasting rigidities that would cause permanent job mismatches. Rather, spells of overqualification are relatively short: about half of all individuals who were overqualified in a given year had an adequate job match 1 year later. While a short duration of overqualification would be consistent with job search and job matching theories, our observation that the probability of a job mismatch does not significantly decrease with experience is at odds with these theories. Our article provides an alternative explanation for this phenomenon: the constant accumulation of experience and qualifications throughout a worker's career implies that, for a good job match to be maintained, qualification-specific job requirements must increase as the worker ages. If this does not occur, even older workers face a risk of becoming overqualified. 相似文献

Based on a rough path foundation, we develop a model-free approach to stochastic portfolio theory (SPT). Our approach allows to handle significantly more general portfolios compared to previous model-free approaches based on Föllmer integration. Without the assumption of any underlying probabilistic model, we prove a pathwise formula for the relative wealth process, which reduces in the special case of functionally generated portfolios to a pathwise version of the so-called master formula of classical SPT. We show that the appropriately scaled asymptotic growth rate of a far reaching generalization of Cover's universal portfolio based on controlled paths coincides with that of the best retrospectively chosen portfolio within this class. We provide several novel results concerning rough integration, and highlight the advantages of the rough path approach by showing that (nonfunctionally generated) log-optimal portfolios in an ergodic Itô diffusion setting have the same asymptotic growth rate as Cover's universal portfolio and the best retrospectively chosen one. 相似文献

Private firms with relatively high (proprietary) costs of disclosure may benefit from a close relationship with a bank. Relationship lending is based on intertemporal contracting that assumes that the bank is able to acquire private information about the firm and, moreover, to keep this information private. For both reasons, we expect and find that private firms with fewer bank relationships exhibit lower levels of financial reporting quality. Controlling for many other factors, firms with a single bank relationship disclose their financial reports about 14 days later. The size of such firms’ financial reports is also smaller, containing approximately 8% fewer words than the median report. Firms with a single bank relationship also exhibit more earnings management, exceeding the median value of the three-year sum of absolute discretionary accruals by about 20%. The results are robust to different econometric specifications, including endogeneity concerns. They indicate that private firms choose to be opaque in the presence of fewer lending relationships. 相似文献
