How important is fiscal policy cooperation in a currency union?

By constructing a dynamic stochastic general equilibrium model, which assumes a currency union consisting of two countries with nontradables, we study the importance of fiscal policy cooperation. As shown in the previous studies, we find that the role of fiscal policy is important in maximizing social welfare. However, we have a contrary result for fiscal policy cooperation. While the previous studies highlight that fiscal policy cooperation has a nontrivial effect in maximizing social welfare, we show that fiscal policy cooperation has no benefits, regardless of the share of nontradables. Self-oriented fiscal policy can replicate social welfare under the cooperative setting.     

The effects of public spending externalities

We conduct a positive analysis on the effects of ‘externalities’ produced by government spending. To this effect, we estimate, using U.S. data, an RBC model with two salient features. First, we allow government consumption to directly affect the marginal utility of consumption. Second, we allow public capital to shift the productivity of private factors. We provide an identification analysis that supports the strategy adopted for estimating the parameters governing these two channels. On one hand, private and government consumption are robustly estimated to be substitute goods. Because of substitutability, labor supply reacts little to a government consumption shock, so the estimated output multiplier is much lower than in models with separabilities. On the other hand, our results point towards public investment being ‘unproductive’.     

上海市交通拥堵成本测算及对策研究

依据美国德克萨斯运输学院交通拥挤外部成本的经典测算模型，将交通运输拥挤成本分为时间延误成本、额外燃油消耗成本、环境污染物排放成本和噪音成本三个方面，对于2015年上海市工作日高峰期交通拥挤的外部成本进行了详细的测算。结果表明，交通拥堵的外部成本约占当年上海市GDP的0.63%。最后，对于交通拥堵成本较高的现状提出了包括对上海市部分高度拥堵路段或区域收取拥堵费、大力发展上海市公共交通和发展交通快慢型出行方式共存在内的相关政策和建议。     

经济政策主要变量对控制中国失业率有效性的实证检验

随着中国经济的增长,失业率却一直居高不下,因此国家采取各种手段进行宏观调控。在回顾各种经济学派对失业理论研究的基础上,着眼于经济政策对控制失业率是否有效,在简要分析货币政策和财政政策对失业率影响的基础上,选取1991—2011年中国城镇登记失业率、货币发行量以及财政支出,通过对三者进行单位根检验和Johansen协整检验,得到三者存在唯一的协整关系,并建立误差修正模型,得出货币发行量对失业率影响较大并且较稳定的结论,并通过格兰杰因果检验,得出货币发行量和财政支出与失业率之间都不存在因果关系,最后在实证研究的基础上对当前中国如何控制失业率提出相应的对策。     

地方财政行为是否驱动了中国贸易 收支的动态调整*——基于异质性动态调整模型的分析

本文利用1997-2013年中国省际层面的面板数据，借助异质性动态调整模型从动态视角考察了地方财政行为对中国贸易收支调整速度的影响。研究结果显示：（1）平均而言，在地方财政行为的驱动下，中国实际贸易收支向最优水平动态调整的速度约为0045。总体表明，地方财政行为对中国贸易收支的驱动性影响较弱，引致实际贸易收支向最优水平调整的速度也较为缓慢。（2）财政支出分权的强化会制约贸易收支的调整速度，贸易收支调整呈现“相对惰性”。财政收入分权的提高和预算内财政支出的扩张能够加快实际贸易收支向最优贸易收支调整的速度，助力贸易收支实现平滑调整。预算外财政支出和财政收入的变化对调整速度则不会产生显著性影响。（3）贸易收支的调整速度呈现显著的区域异质性。本文的结论表明，现阶段中国要实现贸易收支的平衡调整路径，中央及地方政府必须把握好财政行为与贸易收支的动态联动关系。     

Identifying Discretionary Fiscal Policy Reactions with Real‐Time Data

We propose a method of identifying discretionary fiscal policy reactions using real‐time data. Automatic stabilizers should depend on true GDP, while discretionary fiscal policy is contingent on the information that policy makers have in real time. We can compute a real‐time measurement error by comparing the first release of GDP data with later revisions. Discretionary fiscal policy is influenced by this measurement error, whereas automatic fiscal policy is not. We use this identification approach to test the central identifying assumption of Blanchard and Perotti’s (2002) seminal structural vector autoregression (VAR). According to this assumption, fiscal policy makers do not react to GDP developments contemporaneously in a discretionary fashion. We find that government expenditure is adjusted upward if GDP growth in real time is lower than true GDP. This suggests that fiscal policy makers use short‐term funds to buy goods and services in response to their perception of GDP dynamics.     

Designing intergovernmental fiscal transfers for conservation: The case of REDD+ revenue distribution to local governments in Indonesia

A REDD+ scheme would involve the transfer of financial resources to forested developing countries taking part in it. This paper simulates different approaches to the design of intergovernmental fiscal transfers (IFTs), a possible means to channel a REDD+ international payment to local governments which, in several countries, have a certain degree of authority over forest management. Using Indonesia as a case study, the cost-reimbursement and the derivation approaches are tested. It is demonstrated that both approaches could be used. Using the cost-reimbursement approach, localities with more degraded forests would receive a higher compensation per unit of carbon emission reduction than districts with primary forests. Avoiding further conversion of logged-over areas is associated with higher opportunity costs when compared with preventing the conversion of primary forests. In contrast, the derivation approach sets a fixed percentage and rate to distribute REDD+ revenues and ignores the opportunity costs of REDD+ incurred by local governments. The distribution of REDD+ revenues to eligible local governments is based on an assumed market price of carbon credits from REDD+. This paper concludes by discussing the implications of the findings for designing the distribution of REDD+ revenues, both for Indonesia and more generically for other developing countries.     

对大企业外部性问题的研究

在带来巨大经济效益和高速经济增长的同时,大企业的外部性问题因其大规模生产和消费对整个社会和自然环境造成了严重的负面影响。同时对外部性问题的监测手段和技术的不断提升,以及社会大众对外部性问题的强烈关注,迫使大企业在政府监管督促的基础上,应该发挥其主观能动性,积极将其外部性问题内化。     

Structural reforms and fiscal adjustments: policy options for the euro area

This paper analyses the effects of structural reform and fiscal consolidation policies in the Euro Area using a stylized new-Keynesian model. A number of issues are focused upon: (i) the modelling and effects of fiscal consolidation and structural reforms, and (ii) evaluation of alternative reform and consolidation scenarios, including their joint implementation.     

县乡财政困境与财政立宪主义

中国县乡财政困难背后蕴含着深刻的政府与社会、政府之间的关系的矛盾。以往在技术层面上修修补补式的改革不能从根本上解决问题。因此,本文主张采取财政立宪的制度创新思路。包括两个方面的内容,一方面是通过完善法治和建立有效的民主决策监督机制,实现纳税人对政府的根本约束和监督;另一方面是规范政府间的财政分配关系,抑制政府间的过分自利倾向,实现政府间的合理分权与制衡。
