森林资源分权管理及其效应探讨——以大土村的森林资源分权管理为例

近 2 0年来 ,森林资源下放给当地社区管理已成为世界的趋势。我国从 1980年开始林业“三定”以来 ,为发展林业 ,鼓励造林 ,出台了许多林业政策 ,也产生了多种形式的森林资源分权管理模式。如何系统地探索森林资源分权管理的效果及其影响因素 ,以期为当地的森林资源管理提供有效的信息 ,成为人们关注的热点。本文首先就系统地探索森林资源分权管理及其效应的体系进行了论述 ,然后以大土村作为案例 ,就有关内容进行了探讨

关于修改《注册会计师法》的几点意见

随着我国社会主义市场经济体制的建立和不断完善,我国注册会计师行业也得到了迅速发展,出现了很多新情况、新问题,现行《注册会计师法》的很多内容已明显不适应注册会计师事业发展的客观需要,为此,我省财政厅专门成立了课题组,经过广泛调研,现对《注册会计师法》提出以下修改意见。 建立合理规范的注册会计师行业监管体系近年来,会计师事务所审计失败事件、验资纠纷事件时有发生,使得注册会计师行业受到社会的广泛关注和重视。由于《注册会计师法》对注册会计师行业的监管体制没有相应的规定,各相关职能部门的管理职责划分不清,没有问题的…     

Do regional trade agreements really boost trade? Evidence from agricultural products

We evaluate the impact on trade of regional trade agreements (RTAs) using a panel data approach at the detailed product level which exploits exports to third destinations and imports from third origins as benchmarks. This method is robust to both endogeneity and heterogeneity across agreements and across products, and allows differentiation between the impacts of tariff provisions and non-tariff provisions. The analysis covers agricultural and food products for 74 country pairs linked by an agreement entered into force during the period 1998–2009. Our estimate of the mean elasticity of substitution across imports at product level is slightly below four. Counterfactual simulations suggest that RTAs have increased partners’ bilateral agricultural and food exports by 30–40 % on average, with marked heterogeneity across agreements. Also, RTAs are found to increase the probability of exporting a given product to a partner country although this impact is small. Finally, we found non-tariff provisions have no measurable trade impact.     

Cap reform: modelling supply response subject to the land set-aside

This paper uses duality theory to develop a model of European Community agriculture. The model is used to investigate the impact of the land set-aside provision of the recent package of reforms of the Common Agricultural Policy. We assume that producers chose output and variable input levels that maximize difference between revenue and variable cost. By including first-order conditions for the allocation of land across its uses, we impose that the observed allocations are profit-maximizing allocations. To overcome the problem of incorporating many outputs into an estimable production structure, we imposed a priori the restriction that the technology was weakly separable in major categories of outputs. With this restriction, it was possible to model production decisions in stages using consistent aggregates in the latter stages.

Calibration of incomplete demand systems in quantitative analysis

An easily implemented and flexible calibration technique for partial demand systems is introduced, combining recent developments in incomplete demand systems and a set of restrictions conditioned on the available elasticity estimates. The technique accommodates various degrees of knowledge on cross-price elasticities, satisfies curvature restrictions, and allows the recovery of an exact welfare measure for policy analysis. The technique is illustrated with a partial demand system for food consumption in Korea for different states of knowledge on cross-price effects. The consumer welfare impact of food and agricultural trade liberalization is measured.
