我国土地储备机构发展状况分析

通过对全国土地储备机构相关数据的分析,揭示了我国土地储备机构在时间、区域与不同城市等级上的分布情况,结合土地储备制度发展的背景,推演出我国土地储备制度发展的动力机制,即地方政府的利益诉求与国家政策推动的交互作用,并指出我国土地储备发展的重点应由机构的建立转移到内涵的丰富上。     

领导团队相对进步效度动态测评分析

领导团队已经成为现代社会管理的核心方式,以往大多通过领导团队绩效的对照期指标的比值来测算绝对进步效度,文章真实地反映了领导团队在同等参照前提下的有效进步程度,结合团队成员的有效努力程度和个体相对进步指数,应用数据包络分析方法来测算相对进步效度,将有助于领导团     

货币政策的分配效应研究——基于异质性家庭视角

货币政策不仅是应对突发冲击、在短期内迅速实现经济复苏的政策工具,而且具有调节收入分配的功效。通过将异质性家庭和货币政策引入动态随机一般均衡分析框架,文章考察了扩张性货币政策的分配效应。研究发现,降息不仅能够促进李嘉图和经验规则式家庭的消费和就业,而且有助于降低消费不平等和收入不平等。与不考虑不平等因素的货币政策规则相比,考虑消费不平等和收入不平等的拓展规则引致的社会福利损失显著降低。因此,在制定和执行货币政策规则时,不仅应当考虑家庭的异质性,而且应当考虑可能的消费不平等与收入不平等。     

我国城市化滞后若干问题探讨

按人口城市化率的人均GNP对应关系的国际经验参照比较,改革开放以来我国的城市化明显滞后于经济发展水平.现阶段我国人口城市化的滞后基本上是现实城市容量不足型的滞后.国际经验显示的城市化率与人均GNP之间的对应关系,并非完全是城市化与经济发展协调关系的标准.     

R&D competition, absorptive capacity, and market shares

This paper deals with an oligopolistic industry where firms are engaged in cost-reducting R&D activity to maximize their market shares. The existence and uniqueness of a feedback-Nash-optimal R&D strategy for each firm are discussed. Our simulations highlight that variations in spillovers hardly influence the firms' R&D investment, if their absorptive capacities to exploit extramural knowledge depend on their R&D efforts. Moreover, extramural knowledge cannot completely replace in-house R&D. However, a high level of public R&D favors the firm with the most restrictive R&D expenditure constraint and/or with the lowest initial R&D stock, provided it invests in R&D.     

The Impacts of Technology, Trade and Outsourcing on Employment and Labor Composition

Empirical studies of skill-biased technological change are typically based on a simple production or cost function framework and limited information on technology and labor composition. In contrast, we simultaneously assess the impacts of trade, technology, and outsourcing on shifts in labor demand using a dynamic cost function framework and comprehensive measures of workforce composition and investment in technology. Our findings indicate that technological change has had the largest impact on changes in labor composition. However, the indirect impact of trade on shifts in employment augments its direct impact because trade stimulates computerization, which further exacerbates skill-biased technological change.

Financial leverage changes associated with corporate mergers

We empirically examine whether firms increase financial leverage following mergers. Firms could increase financial leverage either because of an increase in debt capacity or because of unused debt capacity from pre-merger years. We find that financial leverage of combined firms increases significantly following mergers. A cross-sectional analysis shows that the change in financial leverage around mergers is significantly positively correlated with the announcement period market-adjusted returns. Further tests indicate that the increase in financial leverage is an outcome of an increase in debt capacity, although there is weak evidence that some of the increase in financial leverage is a result of past unused debt capacity.     

Adjustment of Profits: Evidence from Australian Manufacturing

Studies of industry profitability generally deal with long-run equilibrium models, making no allowance for slow adjustment to equilibrium. In this study, a cross-sectional analysis is carried out against a sample of Australian manufacturing industries at the Australian Standard Industrial Classification (ASIC) four-digit level between 1977–78 and 1984–85. Firstly, a profit model is estimated in equilibrium form as well as allowing for both uniform and variable adjustment rates across industries. The variable adjustment model is superior, with either model implying at least half adjustment to equilibrium within the seven-year sample period. Secondly, results are examined for the impact of firm homogeneity of firms within industries. Homogeneity of firms is found to have substantial impact,increasing both the estimated profits-concentration relationship and the estimated speed of adjustment.
