城市土地价格波动对房地产业的影响——1999～2005年中国20城市的实证分析

本文利用1999～2005年间的数据对我国地价与房价的关系进行了实证研究.研究结果表明房价对地价有显著影响,地价对房价的影响度较小.在对地价与房价互动传导机制进行研究时,提出了3个传导路径,这些路径上的各个变量大都相互影响.通过分析我们还发现金融支持和土地政策在地价与房价变动中扮演着重要角色,抑制房价不能只控制土地价格,还应从金融支持、投资等方面着手,制定更严格的信贷制度,增加房地产交易税和提高居民可支配收入.本文的研究对于政府制定正确的货币政策和房地产业政策具有积极的参考意义.     

Joint outputs and real wage rates

The magnification effect in standard international trade theory asserts that if the relative price of the labor-intensive commodity increases, the real wage will also increase, as will the wage/rental ratio. This result depends upon the assumption that both activities are nonjoint—each combining labor and capital to produce a single output, so that if activities are joint instead, the results are in jeopardy. It is shown that if the difference between the share of commodity one produced in the first activity and in the second activity exceeds the difference between the labor distributive shares in the first activity and the second, an increase in commodity 1's relative price raises the wage/rental ratio. The real wage unambiguously rises in this case if and only if the ratio of the commodity output shares in the two activities exceeds the ratio of labor shares.     

On the timeliness of tax reform

This paper analyzes efficient government reactions to unanticipated tax avoidance. Quickly reforming tax laws to reduce the effectiveness of new tax avoidance techniques prevents widespread adoption, but indirectly encourages the rapid development of new avoidance methods if prior users are permitted to retain their tax benefits. Tax reforms that immediately prevent new avoidance mean that innovators need not fear imitation by competitors, and cannot rely on copying the innovations of others. Such an activist reform agenda diverts greater resources into tax avoidance activity, and might thereby lead to a faster rate of tax base erosion, than would a less reactive government strategy. Efficient government policy therefore entails either the retroactive elimination of tax savings, with possible associated costs, or else a deliberate pace of tax reform in response to taxpayer innovation.     

Domestic and international strategic interactions in environment policy formation

Summary. In this paper, we establish the most possilbe general formulation of the technology governing carbon-gas emission, giving rise to global external diseconomies, and ty to explore into the strategic interactions,both domestic and international, when an individual country decides on the environmental policies. Through the comparison among emission taxes, quotas, and standard in the perfectly competitive private economies, we find that the first two policies are equivalent but they are different in effects by virtue of what we may call the tax-exemption effect of emission standards. Such a difference in the policy effect further affects the other country's welfare through the global externalities, amplified through whether the government can precommit to either the emission tax or the emission standard.

房地产泡沫问题研究

自1998年开始，我国住房制度改革逐步深入，特别是随着福利化分房的结束，住房商品化的开始，房地产业进入了持续快速发展的新时期。山东省房地产产业发展迅速，成为影响GDP增长的重要因素。但与此同时，房地产价格也连续快速攀升。本论文以济南市为例，在收集整理大量有关房地产泡沫资料的基础上，得出了自己对于济南房地产市场的判断：总体发展健康，但同时需要进一步加强防范措施避免泡沫的形成。

试论实物期权及其在会计实证研究中的运用

实物期权是以实物资产为标的物的未来选择权。实物期权的思想目前已被西方的学者广泛地用于会计的 实证研究当中,然而国内却鲜有学者涉足这一领域。因此本文试就此做出简要的介绍,以期起到抛砖引玉的作用。     

我国房地产市场垄断程度研究--勒纳指数的测算

房地产市场的一个重要性质就是竞争的不完全性和垄断力量的存在.勒纳指数是衡量市场垄断程度的一个重要的指标.本文分别针对我国和各省(市、区)的面板数据、各年截面数据以及我国和各省(市、区)的时间序列数据等样本,对房地产市场的勒纳指数(即市场的垄断程度)进行了测算.结果表明,我国房地产市场的垄断程度相当严重;虽然随着市场经济进程的深入和经济的发展,房地产市场的竞争状况逐渐好转,但这一过程非常缓慢;为了确保房地产市场的长期健康发展和居民福利的提高,今后政府应将促进房地产市场竞争作一项基本的方针政策.     

Choosing sides in the trilemma: international financial cycles and structural change in developing economies

ABSTRACT

This paper analyzes the impact of international financial cycles on structural change in developing economies. It is argued that the impact of these cycles depends on the specific combination of macroeconomic and industrial policies adopted by the developing economy. The cases of Brazil and Argentina are contrasted with those of Korea and China. In the Asian economies, macroeconomic policy has been a complementary tool along with industrial policy to foster the diversification of production and capabilities. Inversely, in the case of the Latin American countries, long periods of real exchange rate (RER) appreciation, combined with the weaknesses (or absence) of industrial policies, contributed to the loss of capabilities and lagging behind.     

个人所得税地区间汇算清缴方法研究

综合与分类相结合的个人所得税制改变了个人所得税按来源地缴纳和分享的模式。个人综合所得的所得税征收时实行预扣预缴和次年汇算清缴制度。当个人综合所得来源于多个地区时,需要在不同预扣预缴地区间进行汇算清缴。如何在不同收入来源地分配税收成为地区间汇算清缴制度设计的重要关键。本文首次从税收创造和税后收益分配角度,建立了两个税收分配的合作博弈模型。比较分析发现,使用解决"破产问题"的方法都是把地区的所得和总税收作为给定的参数,没有考虑地区所得和税收之间的生成关系和累进税率。我们的研究证明夏普利值作为合作博弈的解,具有公平性、效率性和单调性,是个人所得税地区间分配方式的合适选择。
