Although the First World War was ultimately decided in the west, historians have emphasized the importance of the often ‘forgotten’ Eastern Front in understanding its complex evolution. This article examines the perception of contemporary foreign exchange traders concerning the relative importance of the Eastern Front over time. Using a newly compiled dataset on prisoners of war and on soldiers killed and wounded, we show that traders were concerned with casualties on both fronts, recognizing the significance of the two‐front war in the early war years. From the autumn of 1916 onwards, traders seemed to believe the key to winning the war lay in the west only.  相似文献

Despite the growing importance of the commercial paper market there is no empirical work investigating the hedging performance of dynamic hedging strategies versus traditional static hedging strategies. This article proposes a dynamic hedging model for commercial paper that takes advantage of time dependencies present in the joint density of commercial paper and T-bill futures. The hedging effectiveness of the dynamic model is compared to that of the static regression model. There is clear evidence that dynamic hedging is superior to static hedging in terms of both total variance reduction and expected utility maximization. These results hold even when transactions costs are explicitly taken into account. © 1998 John Wiley & Sons, Inc. Jrl Fut Mark 18:925–938, 1998  相似文献

Within business literature in general, capabilities have advanced to the prime determinant of the corporation’s economic rents. Within international business literature, it is further assumed that multinational corporations can enhance their pool of capabilities through foreign subsidiaries. Foreign subsidiaries are seen as means to assimilate new capabilities from their local, external network and integrate these capabilities into the multinational corporation. Data from more than 2000 foreign subsidiaries shows that some foreign units actually are endowed with superior capabilities which are useful for other corporate entities. It is argued that the development of critical capabilities within these subsidiaries is driven not only by internal corporate actors, but also by external actors. The analysis provides evidence that the role of different internal and external network partners for capability development varies according to the functional activity under consideration. Thus, subsidiaries benefit from various internal and external network actors in very different ways. The contribution ends with some conclusions and some avenues for future research.  相似文献

The present paper analyzes the value of public information in a general equilibrium economy with imperfect competition. The welfare effects of an improved information system for perfectly competitive economies have been extensively investigated in the published literature. Schlee (2001) shows that the value of information is always negative in exchange economies if an efficient risk sharing mechanism exists. In contrast, in economies with production, better information reduces welfare provided consumers are sufficiently risk-averse ( Eckwert and Zilcha 2000, 2003 ). In the present paper it will be shown that this result is robust if the production sector exhibits monopolistic competition in the Chamberlinian sense. Even so, the inefficiency of equilibria adds further potential for positive welfare effects of improved information. A model is presented where the degree of market imperfection is positively linked to the value of information. If the markup on competitive prices is sufficiently high, the value of information is positive; that is, better information increases economic welfare.  相似文献

This paper empirically examines the theoretically ambivalent relationship between socially responsible investing (SRI) and stock performance. It contributes to the existing literature by considering both the US and the entire European stock markets and by using consistent world-wide corporate sustainability performance data. Our portfolio analysis from 1998 to 2009 is based on the common four-factor model according to Carhart (1997), which comprises market return, size, value, and momentum factors. We show for the US and the European stock markets that SRI is associated with large-sized firms. The insignificant abnormal stock returns for SRI in both regions are the main result of our paper. Therefore, our study supports the view that SRI stocks are correctly priced by market participants, although we cannot rule out that a corresponding mispricing has existed before the beginning of our observation period in 1998.  相似文献

In this paper, we analyze the impact of Financial Times Deutschland (FTD) news on stock prices and trading volumes. Based on a sample of all news about German DAX, MDAX, and SDAX companies published in the news section of the FTD between 2006 and 2010, our results show that articles that contain positive (negative) information are associated with significantly positive (negative) abnormal returns and abnormal trading volumes around their publication. Furthermore, our results show an initial underreaction to these articles and subsequent post-publication drift. Based on the inattention hypothesis, we show that high-attention news (proxied by abnormal trading volume) almost instantaneously moves stock prices to their new valuation levels, whereas the price adjustment process takes much longer following low-attention news. Our results also hold within multivariate regressions where we additionally control for stock-specific characteristics (e.g., institutional ownership, size, and price-to-book ratio) as well as other attention-grabbing events (as measured by ad hoc announcements and cover-page news articles). Finally, we show that results primarily hold in the non-crisis period.  相似文献
