Neoclassical growth models predict that reductions in capital or labor income tax rates are expansionary when lump-sum transfers are used to balance the government budget. This paper explores the consequences of bond-financed tax reductions that bring forth a range of possible offsetting policies, including future government consumption, capital tax rates, or labor tax rates. Through the resulting intertemporal distortions, current tax cuts can be expansionary or contractionary. The paper also finds that more aggressive responses of offsetting policies to debt engender less debt accumulation and less costly tax cuts.  相似文献

通过对油价波动的历史原因、市场内在因素和人为因素的分析可以看出,石油市场已进入一个新时期,油价将变得更加动荡,而且在波动中呈上升趋势。预计新的平均价位大体为每桶20美元。为此,石油公司应积极研究贸易策略,一方面设法使自身免受损失,另一方面还要寻求从价格波动中赢利。只有准备充分,才能够抗御油价的剧烈波动和周期性变化,进而获得生存与发展。  相似文献

This article provides empirical evidence on the intraday relation between spot volatility and trading volume in the Spanish stock index futures market. GARCH methodology is used to estimate spot volatility. We analyze the potential relation between spot and futures trading volume and spot volatility by estimating the corresponding conditional density functions as proposed in Quah (1997). Our results reveal no significant link between those variables. Similar findings arise when expected and unexpected volume is considered. Our results suggest that derivative market is not a force behind episodes of significant spot jump volatility. © 2003 Wiley Periodicals, Inc. Jrl Fut Mark 23:841–858, 2003  相似文献

An Internet presence is a critical early component in the process of building towards a fully operational and unified e‐commerce strategy. E‐commerce has significantly impacted logistics/supply chain strategies and the development and implementation of a website have become key issues for many firms within the transportation industry. This study provides an overview of website content within the motor carrier industry. Content analysis was used to assess the site design, informational content, and the interactive content of 152 motor carrier websites, and to compare the features offered on the Top 100 motor carrier firm websites with those offered on the sites of smaller carrier firms.  相似文献

This study attempts to infuse relationship marketing theory into the study of logistics outsourcing relationships. In particular, the study demonstrates that not all of the partnerships between customers and providers of third‐party logistics services are the same in terms of their level of development. The existence of distinct levels of partnership established previously in the logistics literature is partially supported and a relationship between level of partnership development and the customer perceptions of key relationship marketing elements and outcomes is established. While exploratory in nature, these findings suggest there are benefits for the increased costs of developing closer partnerships.  相似文献

Close relationships between and among supply chain members are becoming more prevalent. However, there is lack of agreement in the literature and in practice concerning the characteristics of different interorganizational relationships. The resultant confusion is an obstacle to the progression of research and could cause problems among firms in a supply chain. Based on previous research and an exploratory study conducted with company executives responsible for supply chain management activities, this article seeks to introduce the concept of relationship magnitude (i.e., the extent or degree of closeness or strength of the relationship) and differentiate it from relationship type (i.e., classes of relationships that share common traits). Implications for managers and opportunities for future research are provided.  相似文献

This paper examines the return of the original class of common stock around the announcement of the creation of a second class of stock. As in previous studies, this one finds a generally ambiguous market reaction on the first public announcement. However, this paper offers new evidence that both the voting rights and the compensation for loss of voting rights are important determinants of the market's reaction. Specifically, it demonstrates that a second class stock issue that contains no compensation for the lost voting rights results in negative returns. When the original stockholders are compensated for lost voting rights, they experience positive abnormal returns.  相似文献
