This article illustrates the progressive move away from traditional accounting practices through a study of the presentation of financial statements. Based on a sample of one hundred large French industrial and commercial groups over a ten-year period, and applying a logistic regression method, our survey confirms a trend among French companies, which are increasingly turning their backs on traditional national practices as regards the balance sheet format, the income statement format, the voluntary disclosure of a statement of changes in shareholders' equity and the cash flow statement format. This move towards 'alternative' practices is made possible by the flexibility of French regulation, and can probably be explained by the desire of French firms to attract more investment on international capital markets. However, this trend shows no signs of a clear orientation towards any particular accounting model (IAS, U.S. or U.K.). The behaviour of the French firms observed in our study can be considered as a kind of 'shopping around' for accounting practices. 相似文献

Where increasing returns to adoption play a role in the diffusion of a new technology, technological “lock-in” is now often claimed to occur. However, this result, and the modeling approach that produces it, are problematic. Further innovations could never have a chance of disseminating, if “lock-in” had occurred in the diffusion process of earlier innovations. Yet, in reality, industrial change does not come to a halt. The paper offers a discussion of the apparent paradox. From an alternative modeling approach conditions are derived under which a newly introduced technology can successfully disseminate in the market despite existing network externalities. 相似文献

We argue that coopetition and standardization are important dimensions in the analysis of general-purpose technologies (GPT). We synthesize ideas from GPT, standardization, and coopetition literatures and introduce a framework for empirical analysis of GPTs that are enabled by standards development and related coopetition. We apply this framework and analyze the role of coopetition in standardization of wireless cellular technology, which has been recently discussed as a GPT. We document that coopetition and standardization have been associated with increasing improvement, innovation spawning, and pervasiveness—the characteristics of GPTs—in the context of wireless cellular technology. The perspective of standardization and coopetition could shed further light on the technological progress and evolution related to emerging GPT candidates, such as artificial intelligence and blockchain. 相似文献

The sharp increase in SEP declarations and declaring firms emphasizes the necessity for understanding firms’ innovation investment behavior in standardization. This paper empirically investigates whether declared standard-essential patents (SEPs) and the declaring firm’s business model (operationalized as a firm’s location in the value chain) are associated with a firm’s innovation investment behavior. To this end, we measure firms’ innovation investment behavior through average total research and development (R&D) expenditures per filed patent family for publicly listed firms from 1999 to 2018. Our sample mainly includes major SEP family declarants. We rely on a binary business model taxonomy differentiating upstream and downstream firms. Within that setting, total R&D expenditures rise with increasing fragmentation of declared SEP families, suggesting that firms adjust their R&D investments to declaration developments in standard-setting organizations (SSOs). We also show that upstream firms have significantly lower total R&D expenditures than downstream firms, which could indicate structural differences in their intellectual property (IP) and R&D management processes. Our results can help SSOs and regulators better understand firms’ innovation investment behavior. 相似文献
