Dividend reinvestment plans: An empirical analysis

This study examines the effect of initiating discount and no discount dividend reinvestment plans on shareholder wealth. The results show a negative response to DRP announcements, which is significantly smaller than that found in studies of new equity offerings. These results are consistent with the Scholes and Wolfson (1989) hypothesis that managers in need of equity capital use DRPs to mitigate the adverse stock price effects of new equity issue announcements. Furthermore, there is a significant difference in the price response of discount and no discount DRPs for industrial firms. This result is supportive of the signaling potential of discount DRPs. Supportive evidence is also found in the analysis of firm characteristics for industrial firms.     

The impact of product diversification strategy on the corporate performance of large Spanish firms

We analyze the impact of product diversification on performance. This topic has been discussed in the literature, and there is no consensus so far as to the significance or the direction of the impact. Performance is measured using Tobin's q for a sample of 103 large, non-financial Spanish firms (1992–1995). Diversification is measured by means of a categorical variable, as suggested by Varadarajan. The principal results indicate that the firms with intermediate levels of product diversification have the highest performance, while the firms with low and high levels of diversification show significantly lower performance, which performance is not significantly different between them.     

Modeling Cyclical Asymmetries in European Imports

This paper applies smooth transition models to capture the nonlinear behavior in the imports data of six major European economies and to assess whether such nonlinearities are related to business cycle asymmetries. Two classes of switch between regimes are considered: endogenously determined transition that assumes nonlinearities are generated by idiosyncratic components specific to foreign trade, and exogenous transition based on GDP growth as a more direct indicator of the cyclical state of the economy. The results support the proposition that the dynamics of imports are nonlinear. In Belgium, France, Spain, and the United Kingdom, regimes change over the business cycle, while in Germany and Italy the switch between regimes is endogenous. National characteristics play a role in defining the position of extreme regimes, the smoothness of the transition, and local dynamics within each state.Previous versions of this article have been presented at the 57th International Atlantic Economic Conference (Lisbon, Portugal, March 10–14, 2004) and at the VII Encuentro de Economía Aplicada (Vigo, Spain, June 3–5, 2004).

MNE competence‐creating subsidiary mandates

The determinants of R&D intensity differ between subsidiaries in a multinational enterprise (MNE). Previous literature suggests that whether a subsidiary achieves a competence‐creating output mandate depends on the qualities of its location. R&D strategies in competence‐creating subsidiaries are supply‐driven while those in purely competence‐exploiting subsidiaries are demand‐driven. Using data on U.K. subsidiaries of non‐U.K. MNEs, we find that the level of subsidiary R&D depends on MNE group‐level and subsidiary‐level characteristics as well as locational factors. The R&D of mandated subsidiaries rises with acquisition, but for non‐mandated subsidiaries R&D falls upon acquisition. MNEs that grow through acquisition have more inter‐subsidiary R&D diversity.

Accommodating spatial correlation across choice alternatives in discrete choice models: an application to modeling residential location choice behavior

This paper presents a modeling methodology capable of accounting for spatial correlation across choice alternatives in discrete choice modeling applications. Many location choice (e.g., residential location, workplace location, destination location) modeling contexts involve choice sets where alternatives are spatially correlated with one another due to unobserved factors. In the presence of such spatial correlation, traditional discrete choice modeling methods that are often based on the assumption of independence among choice alternatives are not appropriate. In this paper, a Generalized Spatially Correlated Logit (GSCL) model that allows one to represent the degree of spatial correlation as a function of a multi-dimensional vector of attributes characterizing each pair of location choice alternatives is formulated and presented. The formulation of the GSCL model allows one to accommodate alternative correlation mechanisms rather than pre-imposing restrictive correlation assumptions on the location choice alternatives. The model is applied to the analysis of residential location choice behavior using a sample of households drawn from the 2000 San Francisco Bay Area Travel Survey (BATS) data set. Model estimation results obtained from the GSCL are compared against those obtained using the standard multinomial logit (MNL) model and the spatially correlated logit (SCL) model where only correlations across neighboring (or adjacent) alternatives are accommodated. Model findings suggest that there is significant spatial correlation across alternatives that do not share a common boundary, and that the GSCL offers the ability to more accurately capture spatial location choice behavior.     

Multi-agent modeling of economic innovation dynamics and its implications for analyzing emission impacts

In this elaboration we focus on the role of multi-agent systems as a tool for modeling economic dynamics. Hence, at the beginning the specific features of this tool are considered. Taking the example of explaining the relationship between innovations and economic growth it will be shown after that how the tool of multi-agent modeling can be used for the following purposes: (1) for explaining the occurrence of innovations, (2) for specifying the effects these innovations have on economic growth, (3) for linking emission impacts to this growth and finally (4) for exemplarily assessing political options to reduce these impacts.     

印度油气供需现状及2025年远景规划

印度目前70％的原油需要进口。预计2011－2012年，石油需求量将由现在的每年1．12亿万吨增至1．9亿万吨。根据印度政府2001年3月制定的《2025年印度油气发展规划》，印度的油气勘探开发部门将在加强已勘探盆地油气勘探开发的同时，扩大对未勘探盆地和油气边缘盆地的勘探；继续实施高度自由的新勘探许可证政策，到2005年使印度超过25％的沉积盆地得到勘探；投资3亿美元，用于提高大型老油田的采收率；鼓励印度国有和私有石油公司参与海外油气勘探开发，并欢迎外国石油公司以各种形式参与印度国内油田的勘探开发活动；提高炼油能力和产品服务水平，促进市场竞争，分阶段取消油品的行政定价机制，实行市场定价；大力推动天然气的消费利用，在努力提高本国天然气产量的同时，允许各石油公司开发液化天然气进口项目；开放了7个煤层气区块，推进煤层气的勘探开发。
