亚洲货币危机视角下的资本账户开放

本文采用1985-1999年泰国、印度、印度尼西亚、韩国、马来西亚和菲律宾的季度数据,运用面板数据的方法,从货币危机的视角进行了实证研究,认为发展中国家的资本账户开放有引发货币危机的可能,但是这种可能性与一国的经济基础条件关系密切,为了避免和缓解发生货币危机的风险,发展中国家应在实现内外均衡和深化金融改革的前提下开放资本账户。     

Degree of Multinationality and Financial Performance: A Study of U.S.-Based Multinational Corporations

This paper examines the marginal benefits that accrue to U.S.-based multinational corporations through increased international investment. Specifically, the study seeks to determine if increased degrees of multinationality produce additional benefits for multinational firms in terms of excess returns and/or reduced risk. The results indicate that during the period studied, the degree of multinationality did not have a significant influence on the risk and return performance of the sample firms. Thus, the study supports the findings of Qian (1996) and Siegel et al. (1995, 1995A) who report that the advantages enjoyed by multinational corporations may be going away.     

财税政策不确定性的衡量——基于适应性学习预期的分析框架

我国财税政策重视短期矛盾调节而忽视长期稳定性,但鲜有研究论及财税政策不确定性问题,其中财税政策不确定性的衡量是重点也是难点。本文在适应性学习预期的分析框架下,对市场主体不同政策学习模式进行甄别,发现我国市场主体倾向于采取重视近期经验的持续性学习策略组成财税政策预期,并且政策预期不能向理性预期收敛,证明我国存在财税政策不确定性。然后,在此基础上构建相应指标来衡量我国财税政策不确定性程度。结果显示,由于财税政策规则不具备动态稳定性以及由此导致预期模式的不稳定,我国财税政策不确定性呈现内生性和系统性特征。本文进一步通过财税政策不确定性的宏观经济效应检验,发现其对生产、物价、出口等产生负面冲击,并且对生产导致符合经典理论的“超调”效应,在一定程度佐证了本文财税政策不确定性指标的一致性。最后,本文对治理财税政策不确定性提出相应政策建议。     

对外开放与我国经济增长的实证分析

本文通过建立对外开放度内生化的生产函数,运用协整方法,对我国对外开放与经济增长的关系进行了实证分析。结果表明:我国的实际产出、对外开放度、实际资本存量与就业人口之间,至少存在单向的因果关系;从长期来看,变量之间存在一种稳定的均衡关系,对外开放度越高,经济增长越快;从短期来看,均衡关系由短期偏离向长期均衡调整的速度较慢。     

产业转移与土地利用的耦合作用机理及协调度评价 ——以环长株潭城市群为例

通过构建耦合协调度模型,运用空间探索分析法评价环长株潭城市群承接产业转移与土地集约利用之间的耦合协调度及时空演变特征。结果表明：整体上,环长株潭城市群承接产业转移与土地集约利用之间的耦合协调度不高,大多处于濒临失调的状态;时间上,2005-2017年八个城市承接产业转移与区域土地利用之间的耦合协调度均朝着协调的方向呈稳定上升趋势;空间上,表现出“以长沙为中心,东高西低、南高北低”的空间分布特征,但差距不断缩小,且在发挥系统整体功能上还有协调发展和深度合作的巨大潜力。     

Analysis of topologies and key players in terrorist networks

While topologies and key player positions and roles differ across terrorist networks, similar ideological networks share similar structures and topologies, maintaining structural properties of their predecessor groups. In this study, we look at basic ideological waves of terrorism in history, classify terrorist network ideologies, and describe the patterns in network topologies and key player characteristics. We show that ideological differences in terrorist networks in part explain the differences in the structure of links between key players.

The optimal degree of commitment in a negotiation with a deadline

Summary. This note explores the consequences of a player's freedom of choice over his degree of commitment for the bargaining outcome. In particular, we modify the nonstationary structure of Fershtman and Seidmann (1993)'s bargaining by allowing one player to possess imperfect commitments where the degree of commitment is chosen prior to the negotiation stage. We show that a player optimally chooses an intermediate degree of irrevocability provided the costs of increasing the degree of commitment are small enough. In this case, not only an immediate agreement is reached but also the commitment is effective.Received: 18 July 2002, Revised: 20 March 2003, JEL Classification Numbers: C78.Part of this work was written while I was visiting the IAE-CSIC and the University of Essex, whose hospitalities are gratefully acknowledged.
