This paper explores the connection between three important threads of economic research offering different approaches to studying the dynamics of an industry with heterogeneous firms. Finite models of the form pioneered by Ericson and Pakes (1995) capture the dynamics of a finite number of heterogeneous firms as they compete in an industry, and are typically analyzed using the concept of Markov perfect equilibrium (MPE). Infinite models of the form pioneered by Hopenhayn (1992), on the other hand, consider an infinite number of infinitesimal firms, and are typically analyzed using the concept of stationary equilibrium (SE). A third approach uses oblivious equilibrium (OE), which maintains the simplifying benefits of an infinite model but within the more realistic setting of a finite model. The paper relates these three approaches. The main result of the paper provides conditions under which SE of infinite models approximate MPE of finite models arbitrarily well in asymptotically large markets. Our conditions require that the distribution of firm states in SE obeys a certain “light-tail” condition. In a second set of results, we show that the set of OE of a finite model approaches the set of SE of the infinite model in large markets under a similar light-tail condition.  相似文献

Drawing upon the corporate social responsibility literature, we investigate the moderating effects of the natural environment and the stage of an organization's life cycle on the market orientation to firm innovativeness relationship. Through 229 owners or chief executive officer respondents, our results establish evidence of (1) a positive linkage between market orientation and firm innovativeness; (2) natural environmental policy positively moderating the market orientation to firm innovativeness relationship; and (3) organizational life cycle negatively moderating market orientation to innovativeness. Our findings suggest ventures characterized as being early in the organizational life cycle are more likely to have a positive environmental policy toward the natural environment leading to a competitive advantage through firm innovativeness.  相似文献

In a study of 257 new ventures from China, India, Mexico, and South Africa, we find support for the mediating effect of strategic early internationalization on international sales intensity. We argued that when new ventures from emerging markets internationalize early and with commitment, the legitimacy they acquire helps them overcome liabilities of newness and foreignness. We develop a typology of international new ventures that, based on strategic intent and timing of internationalization, distinguishes strategic early internationalizers from persistent, serendipitous, and long‐term internationalizers. We show that strategic early internationalization accounts for over half of the explained variance in international sales intensity and either fully or partially mediates the effects of managerial knowledge and market orientation on international sales intensity.  相似文献

This study empirically examines the effect of a non-traditional information source, namely a firm's blog visibility on the capital market valuation of firms. After controlling for earnings, book value of equity and other value relevant variables, such as traditional media exposure, R&D spending, and advertising expense, we find a positive association between a firm's blog visibility and its capital market valuation. In addition, we find blog visibility Grange causes trading, not vice versa. Our findings indicate that non-traditional information sources such as blogs help disseminate information and influence consumers' investment decisions by capturing their attention.  相似文献

Prior research suggests that adoption decisions are primarily based on product features and experiential opportunities, like trial and observation. Our research follows inquiries that identify anticipated regret (AR) as an emotion integral to consumer decision making. Prior research and current retailing practice assume that AR can be alleviated by compelling product attribute-based rationales for immediate purchase. These rationales often take the form of direct attribute comparisons between the current best and the future technologies. Counter-intuitively, we find that giving consumers attribute-based justifications for immediate purchase produces a uniform level of AR and purchase delay regardless of the perceived rate of innovation (PRI). However, under conditions of low PRI and no justification, AR decreases significantly. A clear implication of our findings is that firms marketing current technology should not rush to provide consumers with justifications for immediate upgrade since such communications will remind consumers of what they might miss if they adopt now, resulting in increased AR and purchase delays. Instead, we suggest that retailers focus promotional efforts on highlighting the hedonic benefits consumers experience by adopting today.  相似文献

Franchising has attracted the attention of retailing and entrepreneurship scholars in the past three decades, but evidence pertaining to how franchising affects financial performance is mixed and inconclusive. Thus, the question remains as to whether franchising firms exhibit better financial performance than non-franchising firms in the same industry. In order to find an answer to this question, our study compares the risk-adjusted financial performance of franchising versus non-franchising restaurant firms over the 1995–2008 interval, using five different performance measures: the Sharpe Ratio, the Treynor Ratio, the Jensen Index, the Sortino Ratio, and the Upside Potential Ratio. For each measure, the results revealed that franchising restaurant firms outperformed their non-franchising counterparts. Thus, we provide very robust evidence that franchising is superior on average in the restaurant industry, which can help explain the increasing popularity of franchising as a business form.  相似文献
