论不同金融结构对技术创新的影响

从金融功能出发,分析了不同金融结构——以金融市场为主的金融结构与银行中介为主的金融结构对技术创新的影响。由于银行中介的风险内部化,且在信息处理上不能反映存款人的不同观点,使其不适合为高风险、高收益的高科技产业融资;而金融市场有利于投资者通过资产组合分散风险,且能提供表达不同投资者不同意见的机制,使其更能支持技术创新。这一结论已为发达国家产业发展所证实。在此基础上,解释了我国科技型中小企业融资难的金融制度原因,并提出了有关的对策建议。     

THE SOURCES OF GROWTH AT DIFFERENT STAGES OF DEVELOPMENT

Cross-country growth regressions have become an increasingly common tool in empirical development research. But these regressions typically do not attempt to distinguish among countries in different stages of development. Three empirical methods are used to test for such differences. Several of the factors known to affect economic growth are shown to operate differently for countries in different portions of the global income distribution. The results have implications for the role of financial markets, openness and factor accumulation in promoting growth. (JEL O150 , O160 , O400 )     

延长退休年龄还是增加缴费基数： 养老金改革的路径选择与政策效应*

随着人口老龄化加剧和预期寿命延长,我国养老保险体系面临预期养老金支付严重不足的挑战。本文基于总量视角建立基础养老金收支模型,利用中国人口预测数据,分别测算基于实施“延长退休年龄”和“增加缴费基数”两种不同的改革策略未来30年中国基础养老金的收支余额,并评估政策效果。研究结果表明,“推迟退休年龄”对缓解养老金基金支付压力作用明显,但存在增加就业压力等负外部性。“增加缴费人数”亦可以缓解养老金支付困境,且不存在负外部性,但推行时间缓慢,或将产生新的公共财政压力。     

ON THE EFFECTS OF DIFFERENT PATTERNS OF PUBLIC CONSUMPTION EXPENDITURES

The multiplier effects resulting from an isolated increase in the level of public consumption within different public branches are investigated and the policy implications are discussed. The article begins with a theorethical analysis which shows why and in which ways these multipliers can be expected to differ between public branches. Thereafter, an empirical investigation is given, based on simulations with an econometric model of the Swedish economy. In this model the public activities are divided into 13 different public branches. The effects of an increase in public consumption on employment, imports and private consumption are found to differ considerably depending on which branch of the public sector is expanded. Some implications for short run stabilization policy are discussed. The article ends with a special analysis of the implications for a medium term planning problem: the trade off between private and public consumption growth. This analysis throws new light on the old topic "private or public consumption". In an economy with highly differentiated production in the public sector the trade-off is shown not to be unique. The sacrifice of private consumption growth corresponding to a given growth of public consumption expenditures will vary considerably according to the distribution of the public consumption growth within the different branches of the public sector.
