Equilibrium Determinacy under Monetary and Fiscal Policies in an Overlapping Generations Model

This paper studies the issue of equilibrium determinacy under monetary and fiscal policy feedback rules in an optimizing general equilibrium model with overlapping generations and flexible prices. It is shown that equilibria may be determinate also when monetary and fiscal policies are both 'passive'. In particular, under passive monetary rules, equilibrium uniqueness is more likely to be verified when fiscal policies are less committed to public debt stabilization.     

Conditional Policies in General Equilibrium

Obtaining lower generalized system of preferences (GSP) tariffs requires meeting costly Rules of Origin (ROOs). Growing coffee in the shade is more costly, but yields a price premium. This paper analyzes the effects of such restrictions in a general equilibrium setting and shows that such policies may have unanticipated effects. It is shown that in a world with capital mobility, the GSP could result in capital outflows rather than inflows and consumer preferences for shade grown coffee end up hurting labor in developing countries. Even small subsidies that are contingent on the use of domestic intermediates can result in specialization in the targeted good. Value added contingent policies can easily lead to multiple equilibria despite the absence of externalities or market imperfections.     

人口老龄化影响财政与货币政策的有效性吗?

文章将人口结构、财政支出结构和货币政策引入新凯恩斯动态随机一般均衡框架,重点分析了人口老龄化对我国宏观调控经济政策的影响.研究结果显示:除了人口老龄化自身对经济增长的负面影响,留给宏观调控政策的腾挪空间也越发有限?影响政策调控的有效性,增加政策实施的成本.(1)除了加重财政养老负担,人口老龄化更损害财政刺激效果和财政绩效质量,限制政府实施反周期政策的能力,压缩财政政策发挥的空间;(2)老年人主导的社会对通货膨胀的容忍度将不断下调,势必削弱货币政策刺激总需求能力,增加政策实施成本,迫使中央银行改变货币政策操作方式,可能采取更激进措施以实现相同效果,强化金融脆弱性;(3)相比增加人口生育率,提高劳动参与率既是缓解短期财政养老负担、保障养老融资可持续性的关键,也是有效增加劳动供给、改善政策发挥生态环境,进而提高财政政策与货币政策有效性的权宜之计.     

论财政政策与货币政策的有效搭配

货币政策有效性是近两年争论较多的问题,人们对货币政策效果的理解大都是从货币政策自身变化对经济增长的影响来分析的,事实上,货币政策的效果很大程度上依赖于其它宏观经济政策,尤其是财政政策的变化,因此,分析货币政策的效果要根据其它政策是否配合才能作出合理性判断,笔者认为,必须建立我国货币政策与财政政策有效搭配的协调机制,以及必须把握宏观调控的“度”和“时点”问题。     

Socioeconomic Impacts of Public Forest Policies on Heterogeneous Agricultural Households

Nepal has a long history of returning public forests to local people as part of its community forestry programme. In principle the community forestry programme is designed to address both environmental quality and poverty alleviation. However, concern has been expressed that forest policies emphasise environmental conservation, and that this has a detrimental impact on the use of community forests in rural Nepal where households require access to public forest products to sustain livelihoods. To study the effect of government policies on forest use, an economic model of a typical small community of economically heterogeneous households in Nepal was developed. The model incorporates a link between private agriculture and public forest resources, and uses this link to assess the socioeconomic impacts of forest policies on the use of public forests. Socioeconomic impacts were measured in terms of household income, employment and income inequality. The results show that some forest policies have a negative economic impact, and the impacts are more serious than those reported by other studies. This study shows that existing forest policies reduce household income and employment, and widen income inequalities within communities, compared to alternative policies. Certain forest policies even constrain the poorest households?? ability to meet survival needs. The findings indicate that the socioeconomic impacts of public forest policies may be underestimated in developing countries unless household economic heterogeneity and forestry??s contribution to production are accounted for. The study also demonstrates that alternative policies for managing common property resources would reduce income inequalities in rural Nepalese communities and lift incomes and employment to a level where even the poorest households could meet their basic needs.     

European Monetary and Fiscal Policies after the EU Enlargement

This paper examines the design of macroeconomic policies after Central and Eastern European countries (CEECs) have joined the EU. We consider scenarios with and without CEECs being members of the European Economic and Monetary Union (EMU) and analyze consequences of different intermediate targets for the European Central Bank. For the fiscal policy variables, we assume that the governments of incumbent and new members either refrain from pursuing active stabilization policies or follow either non-cooperative or cooperative activist fiscal policies. Different scenarios are simulated with the macroeconomic McKibbin–Sachs Model (MSG2 Model), and the resulting welfare orderings are determined. They show that the advantages and disadvantages of different policy arrangements depend strongly on the nature of the shock the economies are faced with. Additional macroeconomic noise resulting from the CEECs' membership of the EMU does not seem to be too much of a problem.

Market, Trade and Welfare in General Equilibrium

This paper develops a tractable general equilibrium model of an economy with an arbitrary number of industries under increasing returns to scale and imperfect competition. The market structure of the model economy is expressed by two basic sets of parameters: the degree of competition, and the markup ratio prevailing in each industry. The government is supposed to control the degree of competition through antitrust policy and the markup ratio through entry policy. Using this model, I re-examine the results of traditional competitive equilibrium analysis and explore the effects of competition policies on economic welfare and international trade.

灾难冲击与我国最优财政货币政策选择

本文通过引入政府生产性支出拓展了包含灾难冲击的新凯恩斯DSGE模型,数值分析表明,相对于不含政府生产性支出的灾难冲击模型,该模型能够更好地拟合中国宏观经济波动等基本特征。在此基础上,本文分别在规则行事与相机抉择两种情形下对比分析了我国面对灾难冲击时的最优财政货币政策选择问题,研究发现:(1)应对灾难冲击时,相对于相机抉择,规则行事造成的经济福利损失较低;(2)政府生产性支出可以在一定程度上降低灾难冲击对消费和产出等宏观经济变量的影响,但同时会弱化债务对灾难冲击的吸收作用;(3)引入通货膨胀惩罚(或厌恶)后政府可以更多地倚重于债务发行来吸收外部不利冲击,从而缓解相机抉择下的时间不一致性问题,减少经济福利损失。     

Fiscal policy and economic activity in South Asia

This paper analyzes whether fiscal policy in South Asia amplifies or smoothens business cycle fluctuations. It estimates several econometric models to explore the cyclicality of government spending and tax buoyancy. In South Asia, tax revenue increases less than one to one with changes in gross domestic product (GDP), but public spending increases more than proportionally. For each percentage point change in GDP growth, government expenditure changes by 1.3 percentage points. While changes in tax revenue have no significant impact on economic activity, the government spending multiplier is positive and significant: each additional US dollar (USD) of spending leads to an immediate increase in GDP of 0.2 USD and to an increase of 0.4 USD in the medium run. The impact of public spending on economic activity is entirely due to capital expenditure, which is also more procyclical. Procyclical public spending and a positive expenditure multiplier imply that fiscal policy in South Asia amplifies boom‐and‐bust cycles. These results are in line with those of other emerging markets and developing economies and robust to different model specifications and estimation strategies.

本文通过放松M-F模型的前提条件,分析了浮动汇率制度下大国经济的最佳政策组合,得出了低估本币汇率水平时扩张性货币政策效果明显,高估本币时扩张性财政政策效果明显的结论.作者认为,中国正在向大国经济转型,在资本流动受到管制,货币政策效果不显著的情况下,低估的汇率政策和扩张性财政政策搭配更加适合中国经济发展.     

最优财政和货币政策及其福利效应分析

本文建立了财政和货币政策协作的最优政策模型,并以中国经济为研究对象,以福利效应为最优政策的评估标准,研究了财政和货币政策协作的最优政策机制。分析表明:在Ramsey最优均衡下,财政和货币政策共同作用于通货膨胀和产出目标,以严格通货膨胀为目标的最优货币规则会使得政策的福利损失最小,但货币政策在产出目标、通货膨胀目标以及政策福利损失三者上不能同时兼顾;最优财政规则是趋向缩小收支差,从而趋近于福利损失最小。本文同时使用贝叶斯分析,对中国经济政策2005年第一季度至2009年第二季度的福利效应进行了评估,实证分析表明:样本期间政策的无条件福利损失处于波动状态,经济增长增加了家庭部门的条件福利损失,即经济增长导致跨期消费成本增加。     

我国企业投资对财政货币政策冲击反应的实证分析

本文运用结构向量自回归（SVAR）模型方法研究了我国企业投资对财政货币政策冲击的反应。通过采用1998年1月～2009年4月的月度数据实证研究表明：在经济周期的不同阶段,央行控制货币供给量的能力存在差异,导致货币政策执行效果不同。在经济繁荣阶段,社会资金运用效率较高,不存在剩余流动性,央行可以较容易地通过调整基础货币和货币乘数控制货币供给总量。这时货币供给的外生性较强,货币政策作用效果比较显著;而在经济衰退阶段,可选择的投资机会较少,流动性相对过剩,货币供给内生性增强,这时央行采取扩张性货币政策不能有效提高货币供给量,货币政策作用效果减弱。短期内虽然财政支出对企业投资会产生正向影响,但是负向影响要大于正向影响,也就是说财政政策对企业投资具有明显的挤出效应。     

中国货币经济波动的一般均衡分析

文章构建了一个动态随机一般均衡的模型,从理论和实证两个方面分析了中国货币经济的波动问题.实证结果表明我国经济中货币余额的波动更多地源于消费者货币需求的波动,投资的波动与货币余额的波动关联不大,因此不能简单地以货币余额的变化来判断投资的状况.投资波动、经济增长波动与消费波动存在背离现象,投资造成大量的成本,这是我国经济非均衡的主要表现.文章的结论支持当前的宏观经济调控政策.     

The Role of Fiscal and Monetary Policies in Sustaining Growth With Stability in India*

The performance of the Indian economy in recent years has attracted increasing international interest. This paper focuses on the role of fiscal and monetary policies in the evolution of the Indian economy over the years, with particular attention being given to the reforms undertaken in these policies since the early 1990s. The coordination of fiscal and monetary policies has been crucial in the sequencing of the economic reform process carried out since the early 1990s. Monetary policy aims to maintain a judicious balance between price stability and economic growth. With the opening up of the Indian economy and the spread of financial sector reforms aimed at functional autonomy, prudential strengthening, operational efficiency, and competitiveness of banks, considerations of financial stability have assumed greater importance in recent years alongside the increasing openness of the Indian economy. The biggest challenge facing the conduct of fiscal and monetary policy in India is to continue the accelerated growth process while maintaining price and financial stability. Therefore, the self‐imposed rule‐based fiscal correction at both the national and subnational levels has to be consolidated and carried forward. The existence of a high level of fiscal deficit also contributes to the persistence of an interest rate differential with the rest of the world, which then also constrains progress toward full capital account convertibility. The success achieved in revenue buoyancy through tax rationalization and compliance has to be strengthened further.     

Migration, Jobs and Welfare: A General Equilibrium Analysis

Immigration has been an important element of the economic development of many countries, although in recent years there has been an intensification of doubts about the benefits of further immigration. This paper brings some simple general‐equilibrium modelling tools to bear on the question of the employment and welfare effects of immigration. Employment and taxation effects, rather than wage and distributional effects, are found to be crucial in determining the impact of immigration on the welfare of factor‐owners in the receiving country. These employment effects depend on the type of immigration and the substitutability or complementarity relationships between immigrant labour and unemployed labour. Certain types of immigration are shown to be Pareto‐improving for the receiving country, without any need for lump‐sum transfers. Simple numerical simulations illustrate the results.

(S, s) Inventory Policies in General Equilibrium

We study the aggregate implications of (S, s) inventory policies ina dynamic general equilibrium model with aggregate uncertainty. Firms in themodel's retail sector face idiosyncratic demand risk, and (S, s) inventory policies are optimal because of fixed order costs. The distribution ofinventory holdings affects the aggregate outcome in two ways: variation inthe decision to order and variation in the rate of sale through the pricingdecisions of retailers. We find that both mechanisms must operate toreconcile observations that orders are more volatile than, and inventoryinvestment is positively correlated with, sales, while remaining consistentwith other salient business cycle characteristics. The model exhibits strongamplification for some shocks and persistence to a limited extent.
