Attempting to move away from commodity‐based products into higher value added ones remains one of the key challenges for research and development (R&D) managers. This paper focuses on developing an understanding of these challenges in the UK packaging industry. The research presents evidence from the case of a single firm, within this process industry, that produces commodity products. The paper contributes to Lager's product degradation–upgrade cycle, which illustrates how functional products degrade into commodities unless product functionalities are continually improved. We characterise the ‘upgrade’ aspect within this model. The paper presents the findings of a 3‐year research project with one of the largest packaging manufacturers in Europe. Five barriers are uncovered that hinder firms attempting to increase the level of product differentiation in order to ‘upgrade’.  相似文献

After more than 50 years of self‐regulation of the US auditing profession, the Sarbanes‐Oxley Act of 2002 (SOX) created the Public Company Accounting Oversight Board (PCAOB) as a quasi‐governmental entity with statutory authority to inspect accounting firms that audit public clients. The frequency of this inspection is annual or triennial, based upon the number of public clients the firm audits. We examine the effects of these two levels of inspection frequency on financial reporting quality and audit fees for clients of small and midsize public accounting firms. Our findings provide evidence of significantly higher audit quality and audit fees for clients of annually inspected firms relative to clients of triennially inspected firms. These findings are robust to auditor‐client alignment analyses, propensity score matching, time‐series analyses, examination of firms that have changed from triennial to annual inspection, and particular examination of firms with inspection deficiencies. Overall, our study suggests that the two‐tier frequency system of PCAOB inspection may have also resulted in two‐tier audit quality and audit fee systems for small and midsize public accounting firms, with more frequent inspection leading to more rigorous and informed auditor decisions. We discuss the implications of our results for the Board and the profession at large.  相似文献

This introduction outlines some key aspects of an Austrian perspective on innovation, which is viewed as an ongoing, dynamic process in which entrepreneurs combine heterogeneous capital resources in new ways order to develop and deploy new technologies, products, and methods of business organisation. It goes on to introduce the contributions to this special issue on Austrian economics and innovation.

The essays collected in this forum discuss the geopolitical legacy of the Russian Revolution of 1917, one of the most momentous political events of the twentieth century. From a range of different academic disciplines and perspectives, the authors consider how the profound transformations in society and politics were refracted through space and geography, and how enduring these refractions proved to be. The authors focus on three themes that have been dominant in Russian affairs over the past century: 1)the problem of center-periphery relations, 2)the civilizational dynamics of Russia’s self-identification in relation to Europe and to Asia, and 3)the geopolitics of national identity.  相似文献
