应对疫情冲击的财税政策建议

公共财政的主要职能就是提供满足公共需要的产品与服务,公共卫生是其重要组成部分。面对新冠肺炎疫情,财政需要在支持抓好疫情防控工作的前提下,深入系统分析新冠肺炎疫情对我国经济社会发展造成的影响,进一步发挥财政职能作用,帮助企业渡过难关、恢复生产,努力保持经济社会平稳健康发展。     

经济发展中的地方官员行为研究——基于政治晋升、财政分权与腐败的视角

本文同时考虑财政分权、政治晋升和腐败三个因素对地方官员行为的影响,进而构建了理论模型。从中得到的主要结论是,在基本模型中,地方官员对政治晋升的偏好程度越高,则其努力程度越高、腐败程度越低。而财政分权程度越高,官员的努力也越高,但对腐败水平影响却是不确定的。在进一步假设腐败会被惩罚的拓展模型中,基本模型的大部分结论都没有发生太大变化,只是分权程度的对努力的影响也变得不确定了。除此之外,我们进一步研究了,对官员腐败惩罚的力度和对官员腐败的惩罚准确程度的影响,相关命题表明,如果对官员腐败惩罚的越严厉,并且对官员腐败的惩罚越准确,官员努力水平和官员腐败程度都会变低。通过对研究结论的分析,我们还对以往文献的结果进行了重新解释。     

地方政府财政支农支出与农村居民消费——来自中国29个省市面板数据的经验证据

本文在消费者最优消费路径选择的基本框架下,构建了一个政府财政支农与农村居民消费的动态最优化模型,理论分析表明:地方政府财政支农支出的增加,对于农村居民消费水平的提高具有促进作用。基于1995-2008年的省际面板数据,采用工具变量GMM方法对该结论进行的实证检验发现:在通过多工具变量克服变量内生性之后,地方政府财政支农支出对农村居民消费具有显著的促进作用,地方政府财政支农支出每增加1%,我国农村居民消费将增加0.1367%;进一步的因素分解显示,地方政府财政支农支出对农村居民消费的平均贡献度为8.72%,且有逐年增大的趋势。此外,财政支农支出对农村居民消费的影响存在区域差异性,即财政支农支出对我国中西部地区农村居民消费的影响程度大于东部地区。     

财政赤字、金融发展与经济增长：省级面板数据实证研究

本文在概括性描述我国金融发展的典型事实并重新构造度量指标的基础上,利用省级面板数据实证分析我国金融发展的决定因素,证实地方政府的财政收支行为对我国金融发展有显著的作用,其中财政赤字对经济货币化指标具有显著的正向影响,对重新构造的金融相关比率具有显著的正向作用,对以股票资产交易额衡量的资本市场发展指标具有显著的反向影响;而金融发展指标对经济增长的效应不显著,政府的扩张性支出行为驱动的金融发展即通过提高资本积累而不是资本效率促进经济增长,但这种增长的可持续性是不容乐观的。金融体系的进一步发展有赖于深化财政体制改革和创新公共融资模式。     

公募基金与阳光私募基金经理的投资能力实证分析

我国公募基金与阳光私募基金的发展从20世纪80年代末至今得到了长足的发展。主要采用TM模型和HM模型对基金经理的选股能力和择时能力进行了对比分析,总体来看,私募基金经理的投资能力优于公募基金经理。当用成功概率法进行辅助性验证的时候,发现两种激励模式下基金经理对市场方向的预测和判断基本相当,公募基金经理还略胜一筹。分析结果,我国基金行业基金经理的投资能力不具备显著的差异,投资业绩的差异关键在于对仓位的控制以及策略的灵活性。     

“省直管县”改革会损害地级市的利益吗?

我国多个地区正在探索"省直管县"体制改革,目前的最大顾虑是改革是否会损害地级市的利益?本文利用1999—2008年我国地级市数据,通过系统GMM估计对此进行了实证研究。结果发现:"强县扩权"提高了城市财政收入,抑制了城市财政支出增长;财政"省直管县"的作用则恰好相反。"强县扩权"促进了城市经济增长,但不利于城市第三产业的发展;财政"省直管县"虽然降低了城市经济增长速度,却提高了第三产业比重。两项改革措施都抑制了城市规模的扩大,但有利于改善城市的环境质量。因此,我们不能笼统地断定"省直管县"改革一定会有损地级市的利益、阻碍城市化的进程,应深入地研究各项改革措施的利弊得失,做到综合运用、扬长避短。     

中国股票型基金业绩持续性实证研究

本文采用动量检验法和回归系数法,检验了存续时间超过24个月的中国股票型基金业绩是否存在持续性.结果发现,101只样本基金的业绩在6个月存在显著的持续性.在此基础上,本文从风险收益和基金管理人能力两个角度检验了基金业绩持续性的来源,结果发现,CAPM和“三因素模型”,以及考虑了基金投资风格的管理人选股能力、择时能力及投资风格持续收益,均不能解释中国股票型基金的业绩持续性.     

Monetary–fiscal policy interactions and fiscal stimulus

Increases in government spending trigger substitution effects—both inter- and intra-temporal—and a wealth effect. The ultimate impacts on the economy hinge on current and expected monetary and fiscal policy behavior. Studies that impose active monetary policy and passive fiscal policy typically find that government consumption crowds out private consumption: higher future taxes create a strong negative wealth effect, while the active monetary response increases the real interest rate. This paper estimates Markov-switching policy rules for the United States and finds that monetary and fiscal policies fluctuate between active and passive behavior. When the estimated joint policy process is imposed on a conventional new Keynesian model, government spending generates positive consumption multipliers in some policy regimes and in simulated data in which all policy regimes are realized. The paper reports the model's predictions of the macroeconomic impacts of the American Recovery and Reinvestment Act's implied path for government spending under alternative monetary–fiscal policy combinations.     

Inflation and the fiscal limit

We use a rational expectations framework to assess the implications of rising debt in an environment with a “fiscal limit”. The fiscal limit is defined as the point where the government no longer has the ability to finance higher debt levels by increasing taxes, so either an adjustment to fiscal spending or monetary policy must occur to stabilize debt. We give households a joint probability distribution over the various policy adjustments that may occur, as well as over the timing of when the fiscal limit is hit. One policy option that stabilizes debt is a passive monetary policy, which generates a burst of inflation that devalues the existing nominal debt stock. The probability of this outcome places upward pressure on inflation expectations and poses a substantial challenge to a central bank pursuing an inflation target. The distribution of outcomes for the path of future inflation has a fat right tail, revealing that only a small set of outcomes imply dire inflationary scenarios. Avoiding these scenarios, however, requires the fiscal authority to renege on some share of future promised transfers.     

Monetary and fiscal policy interactions in the post-war U.S.

A New Keynesian model allowing for an active monetary and passive fiscal policy (AMPF) regime and a passive monetary and active fiscal policy (PMAF) regime is estimated to fit various U.S. samples from 1955 to 2007. The results show that data in the pre-Volcker periods strongly prefer an AMPF regime, even with a prior centered in the PMAF region. The estimation, however, is not very informative about whether the Federal Reserve's reaction to inflation is greater than one in the pre-Volcker period, because much lower values can still preserve determinacy under passive fiscal policy. In addition, whether a PMAF regime can generate consumption growth following a government spending increase depends on the degree of price stickiness. An income tax cut can yield an unusual negative labor response if monetary policy aggressively stabilizes output growth.
