Sequential Malmquist Indices of Productivity Growth: An Application to OECD Industrial Activities

The paper applies both the standard DEA methodology with contemporaneous frontiers and DEA with sequential frontiers to study changes in productivity and efficiency in manufacturing for a sample of eleven OECD countries over a twenty-year period. It uses a decomposition of the industrial Malmquist productivity indices to locate the sources of productivity growth: 'technical progress' and 'catching up.' The alternative indices are interrelated in a unifying framework that provides an interpretation to their difference. We argue that for manufacturing industries, in which technological regress is unlikely to occur, DEA with sequential frontiers provides a more adequate measure for the contribution of technical changes than standard DEA.

Land use externalities, open space preservation, and urban sprawl

Parcel data on residential land conversion are used to investigate how land use externalities influence the rate of development and modify policies designed to manage urban growth and preserve open space. Several “smart growth” policies are found to significantly influence land conversion, including a development clustering policy that concentrates development and generates preserved open space. In addition to directly affecting a parcel's hazard rate of conversion, this policy is found to affect neighboring parcels' conversion by generating a positive open space externality that hastens their development. The implication that the clustering policy could generate a more sprawled pattern of development is explored using spatial simulation.     

Sources of Sectoral Growth in an Economy Wide Context: The Case of U.S. Agriculture

Growth in U.S. agriculture is linked to the non-farm economy through domestic terms of trade and factor market adjustments. With almost stable input growth, the relatively large contributions from growth in Total Factor Productivity (TFP) are passed on to intermediate and final consumers in the form of declining real prices for primary farm products. The resulting net growth in the real value of farm output (GDP) is relatively low (0.25% per annum). The decomposition of TFP suggests that public agricultural stock of knowledge and infrastructure are robustly associated with TFP growth, while spill-overs from private agricultural and economy wide research and development (R and D) are positive but, relatively small.     

我国城市化危及土地资源持续利用的立法原因探析

随着我国城市化进程的不断加快 ,土地资源供给的有限性与人们对土地资源需求的无限性之间的矛盾日益突显。而在此背景下重新修订公布的《土地管理法》在涉及建设用地需求的无限扩展与农业用地数量的持续下降这两个突出问题上 ,并没有明确政府的职能定位 ,也反映出了相关制度的模糊性。本文就此进行了探讨。     

Factor taxation and labor supply in a dynamic one-sector growth model

This paper studies a class of AK-type growth models with factor income taxes, public capital stock and labor–leisure trade offs. While a higher capital tax rate reduces economic growth in the short run, the long-term growth effect is ambiguous and remains ambiguous even if the level of tax rate is larger than the degree of government externality. A higher labor income tax rate has ambiguous growth effects both in the short and long runs. However, if the intertemporal elasticity of substitution for labor supply is sufficiently small, a higher labor tax rate always lowers economic growth in the long run, despite the existence of productive government taxation.     

多主体投资对经济增长贡献的回归分析

在市场经济条件下,多种资本的联合、重组和流动是促进经济发展的重要手段之一。本文根据道格拉斯生产函数、以改革开放近20年来的国有投资、集体投资和个体投资数据为样本构造了多主体投资生产函数,并进行多主体投资对经济增长的回归分析。     

宅基地使用权转让的法律路径——兼评《物权法草案》第162条

设计宅基地使用权的转让制度既要充分考虑我国农村的现实，又要保持相关规则之间的协调。“一户一宅”原则宜表述为“一户只能申请一处宅基地”。物权法对宅基地使用权的转让可以进行必要的限制，但不宜作出绝对的禁止性规定，应当允许宅基地使用权在一定条件下和一定范围内转让。非本集体经济组织成员受让宅基地使用权有其必要性，但必须予以限制。宅基地使用权转让的登记制度，可统一采用“未经登记，不发生物权的效力”的处理模武。     

完善农村土地承包经营权的立法思考

农村土地承包经营权制度自从 2 0世纪 70年代末在中国实行以来 ,取得了巨大成就 ,推动了农村社会经济发展。但在实施过程中 ,由于其表现出债权的特征而逐渐暴露出种种弊端。以物权关系改造现行土地承包经营权制度 ,已成为法学界的共识。物权立法应就土地承包经营权的取得、效力、消灭等作出具体详细的规定 ,使之形成一整套完整的土地承包经营权法律制度     

所有制结构和产业结构对经济增长影响的比较分析

市场化改革以来,国家一方面针对国有企业效率低下等问题实施了所有制结构的转变,另一方面,根据经济的发展程度和居民的生活要求等因素实现了产业结构的调整。但是究竟是所有制结构的转变还是产业结构的调整对经济增长的影响程度更强呢？本文通过运用Cobb-Douglas生产函数和Panel data模型分析得出所有制结构的转变对经济增长的影响程度较产业结构转变的影响程度强,为具体的政策分析和制度创新提供了一定的理论依据。
