税源建设与产业结构调整——源自湖南省统计数据的实证研究

税收作为国家制度性工具,在长期时间序列分析中,税率变化幅度较小,征管作用趋于弱化,仅有经济与税收呈现长期稳定的关系。选取湖南省税收增长率和第二、三产业中的六大主要行业进行多元线性回归分析,实证结果显示：第二产业与税收收入相关度较高,贡献率较大;传统服务业与税收收入相关度较低,贡献率较小;房地产行业对税收收入贡献为负数。

Invertible and non-invertible information sets in linear rational expectations models

Rational expectations solutions are usually derived by assuming that all state variables relevant to forward-looking behaviour are directly observable, or that they are “…an invertible function of observables” (Mehra and Prescott, 1980). Using a framework that nests linearised DSGE models, we give a number of results useful for the analysis of linear rational expectations models with restricted information sets. We distinguish between instantaneous and asymptotic invertibility, and show that the latter may require significantly less information than the former. We also show that non-invertibility of the information set can have significant implications for the time series properties of economies.     

Regime switching and oligopsony power: the case of U.S. beef processing

In this article, we estimate a model of oligopsony behavior under imperfect monitoring of rival actions to analyze weekly marketing margin data for the U.S. beef packing industry. Oligopsonists are hypothesized to follow a discontinuous pricing strategy in equilibrium, and we focus on shocks in the normal throughput of supply as a potential catalyst for regime switching between cooperative and noncooperative phases. We adopt an algorithm developed by Bellone (2005) that relies on Hamilton’s (1989) multivariate first‐order Markov process to test for the cooperative/noncooperative switching behavior. We find strong evidence that links switching conduct by packers to disruptions in coordinating the derived demands for processed beef with the supply of live cattle. Once switched, cooperative regimes lasted an average of 21 weeks, while noncooperative regimes averaged 33 weeks. The average marketing margin for processed beef was 68% lower in the noncooperative regimes compared to the cooperative regimes. This led to an annual average increase in profits of 408 million dollars to the beef packing industry and about an 8–9% reduction in live cattle prices.     

基于生态足迹模型的广西铜匠村生态状况实证分析

以生态足迹模型为途径,以在广西铜匠村的实地入户调查所取得的生态现状数据为基础,对村庄的生态足迹账户和生态承载力账户进行实证分析。对于外出务工者在生态足迹理论中的影响,创新性地提出了其时间加权折算法。结果显示:2009年铜匠村人均生态赤字为1.014 16,生态承载度为37.205%,生态环境状况较差。针对这种生态环境结构,提出了有效的改善措施。     

Foreign Aid and Regime Change: A Role for Donor Intent

This paper uses data from the AidData project to analyze the association between foreign aid and the likelihood of democratization in aid recipients. Previous studies have argued that aid can entrench dictatorships, making a transition less likely. I find evidence that the relationship between aid and democratization depends on characteristics of the aid donor. During the period from 1992 to 2007, aid from democratic donors is often found to be associated with an increase in the likelihood of a democratic transition. This is consistent with a scenario in which aid promotes democratization and/or a situation in which democratic donors reward countries that take steps in a democratic direction. In either case, it suggests that democratic donors use scarce aid resources to encourage democracy. During the same period, aid from authoritarian donors exhibits a negative relationship with democratization. This suggests that the source of funding matters, with donor preferences regarding democracy helping to determine the link between aid and democratization.

世界经济波动对我国外商投资影响的估计

以10个主要国家（地区）为代表,本文用时间序列方法估计了世界经济波动对我国外商投资的影响。实证结果表明,韩国、新加坡和美国的GDP增加（或减少）1个百分点将引起其对我国的外商投资增加（或减少）4~5个百分点,而日本和欧洲国家的GDP增加（或减少）1个百分点将引起其对我国的外商投资增加（或减少）8个百分点以上。总体上看,世界GDP变动1个百分点将引起我国的外商投资变动5.7个百分点。
