In the usual model of product market search, a low search cost can turn out to have detrimental incentives on new product introduction as the low search cost erodes firms’ market power, attenuating the profit from innovation. This paper studies a model of monopolistic competition with costly search, where the point of departure is that of a fixed cost of initiating search. In this environment, a low search cost could turn out to be favorable to innovation. At a low search cost, more consumers may decide to start searching, possibly resulting in higher profits for firms in the larger market, despite the erosion of market power.  相似文献

We examine market reactions to contemporaneous announcements of current earnings and future earnings guidance for evidence on how investors trade off relevance and reliability. Current earnings are more reliable than future earnings guidance, but future earnings guidance may be more relevant for predicting future performance. We find that current earnings are more strongly associated with announcement-period returns than concurrently disclosed future earnings guidance, consistent with investors’ relative preference for reliability. We find similar return reactions to stand-alone earnings and to earnings released with guidance. In contrast, return reactions are lower for guidance announced simultaneously with current earnings than for stand-alone guidance.  相似文献

To study the market quality of commodity futures markets, we construct a commodity futures market quality index from the perspective of liquidity, efficiency, and volatility. Based on the market quality index, the Chinese commodity futures market operates steadily. The metal futures market is more efficient and stable than the market for agricultural futures. The Chinese commodity futures market is less liquid and more volatile than the U.S. market. We examine the determinants of market quality and find that macroeconomic variables and futures market contracts are significantly related to the market quality of Chinese commodity futures.  相似文献

Integrating agency and institutional perspectives, we describe how China’s socio-political institutions create state-owned corporate empires with unique agency conflicts. We develop a framework demonstrating how economically unjustified firm expansion, i.e. empire building, mediates the relationship between state ownership and performance. We uncover the instrument in empire building and appropriate corporate governance and strategic management remedies. An empirical study on 29,638 Chinese firms evidences that (1) increased state ownership drives higher management expenses and lower firm profitability though empire building; (2) long-term debt is used to finance empire building; and (3) foreign capital investments and innovativeness can mitigate these agency conflicts.  相似文献

We investigate whether the reputation-herding theory or the tradeoff theory explains variation in the timing of individual analysts’ forecasts. Using forecast accuracy improvements, forecast boldness, and the price impact of forecasts as measures of forecast quality, we find that in the information discovery phase that precedes an earnings announcement, earlier forecasts have higher quality than later forecasts. We also find a similar pattern in the information analysis phase that begins with the earnings announcement date. Our findings suggest that consistent with the herding theory, analysts who are more capable participate early in discovering and analyzing information, and therefore earlier forecasts in the information discovery and analysis phases are of higher quality than later forecasts in that phase.  相似文献

In October 2006, the NYSE began rolling-out phase three of a four-phase plan initiate its new Hybrid trading mechanism. The results show that this new trading platform introduced a much larger proportion of electronic transactions relative to floor auction transactions. This migration to electronic transactions is further evidenced by a mirror shift in price discovery from floor trades to trades marked for automatic electronic execution. In addition, the move to Hybrid trading introduced a significant decrease in inventory control costs, as well as a noticeable increase in trade persistence. Finally, the new trading platform has increased the speed with which orders are met, and has also decreased the proportion of executed shares which receive price improvement.

This study tests the model of the relationship between corporate entrepreneurship and strategic management, developed for the manufacturing industry by Barringer and Bluedorn (1999 Barringer, B. R. and Bluedorn, A. C. 1999. The relationship between corporate entrepreneurship and strategic management. Strategic Management Journal, 20: 421444. [Crossref], [Web of Science ®] [Google Scholar]), in the hospitality industry. The findings show some similar and different results from the research of Barringer and Bluedorn (1999 Barringer, B. R. and Bluedorn, A. C. 1999. The relationship between corporate entrepreneurship and strategic management. Strategic Management Journal, 20: 421444. [Crossref], [Web of Science ®] [Google Scholar]). Like manufacturing companies, hospitality companies perceive that corporate entrepreneurship is influenced by four strategic planning practices: environmental scanning intensity, planning flexibility, planning horizon, and locus of planning. Hospitality companies, however, consider that financial controls, not strategic controls, positively influence corporate entrepreneurship intensity. These findings have practical applications for hospitality corporations that are attempting to become more entrepreneurial, and will also help researchers to better understand the relationship of corporate entrepreneurship and strategic planning.  相似文献

We explore the role of trade volume, trade direction, and the duration between trades in explaining price dynamics and volatility using an Asymmetric Autoregressive Conditional Duration model applied to intraday transactions data. Our results suggest that volume, direction and duration are important determinants of price dynamics, while duration is also an important determinant of volatility. However, the impact of volume and direction on volatility is marginal after controlling for duration, and the impact of volume on volatility appears to be confined to periods of infrequent trading.  相似文献
