基础设施建设支出、结构性减税与最优政策选择

财政政策的最优政策选择问题对于国家宏观调控政策的出台具有指导意义。既往的研究忽略了利用动态一般均衡的方法探求具有双重外部性的基础设施建设支出与结构性减税支出的政策选择问题。本文利用引入基础设施建设支出和结构性减税的新凯恩斯DSGE模型,测算比较基建支出和结构性减税的政策福利效应。研究表明：具有双重外部性的基础设施建设支出不仅可以通过提高生产效率的方式促进产出,还可以通过挤入居民消费的方式加强政策福利效应。经过测算,短期的基建支出乘数大于结构性减税的政策乘数。同时,基建支出长期平均产出乘数小于结构性减税的平均产出乘数。与结构性减税政策相比,增加基建支出对于财政资金有限的政府是短期内更加有效的产出刺激政策,但在长期中,结构性减税政策不仅具有较高的政策效应,还可以从消费、劳动、投资等角度实现结构性政策目标。进一步研究发现,地区经济发展水平的不同会导致各地区的最优政策选择存在差异性：发达地区可以通过结构性税收政策解决结构性问题的同时实现长期经济增长;而欠发达地区则更应该注重运用基础设施建设为主的支出政策以促进经济增长;但随着人口逐渐从欠发达地区流出,提高欠发达地区的基建支出是否是可行之策,还需要考虑区域协调发展等诸多因素。     

Unionization,market structure,and economic growth

This article investigates the macroeconomic effects of unionization in a Schumpeterian growth model with an endogenous product market structure and a unionized labor market. The endogeneity of the market structure and the trade unionism of the labor market interact and jointly determine the equilibrium unemployment, firm size, number of firms, economic growth, and distribution of income between workers and firms. We show that unionization governs the distribution of income between workers and firms and the unemployment rate, but it does not give rise to any growth effect on the economy. In addition, unionization discourages potential entrants and hence decreases the equilibrium number of firms. These results echo the empirical observation in the sense that unionization raises unemployment and alters the distribution of income between workers and firms, but it does not give rise to a significant, real impact on the firms’ investment and the economy‐wide growth.     

台湾投资祖国大陆对岛内就业的影响——基于制造业的实证分析

本文在对经济数据进行统计分析的基础上,通过建立计量模型,运用协整方法对台湾岛内失业率上升的因素进行了实证分析。实证研究结果表明:台商对大陆的投资活动并非是造成台湾失业率升高的主要原因;而且长期来看,对大陆的投资改善了岛内劳动力就业质量,提高了企业的竞争力。文中还指出,岛内失业率上升的主要原因是产业结构升级和宏观经济环境低迷,加强两岸经贸合作是台湾改善经济环境和降低失业率的明智选择。     

AN ANALYSIS OF ECONOMIC INFRASTRUCTURE INVESTMENT IN SOUTH AFRICA

This paper analyses long‐term trends in the development of South Africa's economic infrastructure and discusses their relationship with the country's long‐term economic growth. A database covering national accounts data, railways, roads, ports, air travel, phone lines and electricity was established for this purpose, and may facilitate further quantitative research. PSS (Pesaran, Shin and Smith, 1996, 2001) F‐tests are used to identify directions of association between economic infrastructure and economic growth. These indicate long‐run forcing relationships from public‐sector economic infrastructure investment and fixed capital stock to gross domestic product (GDP), from roads to GDP, and from GDP to a range of other types of infrastructure. There is also evidence of potential simultaneity between specific types of infrastructure and GDP. The evidence suggests three main findings. Firstly, the relationship between economic infrastructure and economic growth appears to run in both directions. Inadequate investment in infrastructure could create bottlenecks, and opportunities for promoting economic growth could be missed. Secondly, South Africa's stock of economic infrastructure has developed in phases. Policymakers should focus on choosing or encouraging the right type of infrastructure at the right time. Thirdly, the need for investment in economic infrastructure never goes away. The maintenance and expansion of infrastructure are important dimensions of supporting economic activity in a growing economy, provided that individual projects are chosen on the basis of appropriate cost‐benefit analyses.     

Public Revenue‐Expenditure Nexus in South Africa: Are there Asymmetries?

This paper re‐examines the government revenue and expenditure relationship in South Africa using Enders and Siklos' Threshold adjustment and Granger causality tests. The paper allows for structural breaks in the unit root and cointegration tests. The results indicate the absence of any asymmetries in both the threshold autoregression and momentum threshold autoregression specifications of adjustments in the South African's budgeting process. The estimated symmetric error‐correction models provide support for the fiscal synchronization hypothesis of government revenues and expenditures for long‐run and short‐run dynamic equilibrium. These findings indicate that the South African fiscal authorities should try to maintain or even improve the control of their fiscal policy instruments to sustain the prudent budgetary process.     

我国财政支出对民间需求影响的动态分析(1978～2007)

本文把包括居民消费需求与民间投资需求在内的民间需求作为一个整体,利用时变参数(TVP)模型考查改革开放三十年来我国财政支出对其的影响关系.结果显示,改革开放三十年来,我国财政支出对民间需求一直存在着引致(挤入)效应,但其引致弹性系数却经历了一个倒V型的轨迹变化.在财政的分类支出中,用于基本建设方面的支出和用于改善民生的支出对民间需求均有引致效应,且后者的引致效率要远高于前者;政府部门经费支出对民间需求的影响则经历了挤出→挤入→挤出的变化过程.     

Can good events lead to bad outcomes? Endogenous banking crises and fiscal policy responses

In this paper, we study the impact of changes in the urban labor force and foreign direct investment on the banking sector, using a dynamic general equilibrium model with a financial sector. Numerical simulations are performed using stylized Chinese data, and bank failures are generated through increases in the growth rate of the labor force, a revaluation of the exchange rate, or an increase in debt issue to finance the government deficit, as compared to a benchmark scenario in which banks remain solvent. Thus bank failures can result from what might seem to be either beneficial economic trends or correct monetary and fiscal policies. We introduce fiscal policies that modify relative factor prices by lowering the capital tax rate and increasing the tax rate on labor. Such policies can prevent banking failures by raising the return to capital. It is shown that such fiscal policies are, in the short run, welfare reducing.     

交通投资对中国经济增长的影响

许多发展经济学家论证了基础设施建设对发展中国家经济增长的重要性。本文收集中国28个省份1985—2006年的面板数据验证交通投资对我国经济增长的影响。基于系统广义矩估计（GMM）方法,本文得到的结论是交通运输投资对经济增长有着显著的正向影响,其短期和长期的产出弹性分别为0．023和0．062。这也就是说交通运输投资每增加1个百分点,从短期来看将会导致经济增长0．023个百分点,从长期来看将会导致经济增长0．062个百分点。     

Cooperative Monetary and Fiscal Policies in the Euro Area

This article discusses the interaction of fiscal and monetary policy in the euro area. Though many observers suggest a fiscal union as the next step of euro-area constitutional reform, a federal fiscal union does not appear politically feasible in the short run. We suggest moving forward with cooperative monetary and fiscal institutions and policies that allow for decentralized fiscal decisions, while taking federal stabilization policies into account. This approach will increase the probability of survival of the euro area compared with the current fiscal arrangements. Using a dynamic macro model, counterfactual simulation paths of our cooperative solution are contrasted with time-series data for the euro area.     

Institutional wage-setting,labour demand and labour supply: Causal estimates from a South African pseudo-panel

Unemployment in South Africa has multiple causes. This article uses a district pseudo-panel to estimate the elasticity of labour demand, labour supply and unemployment with respect to wages. We assess whether hiring decisions are more sensitive to increases in wages of low-paid workers than high-paid workers, and whether wage growth prompts entry into the labour market. These channels combine to result in the positive causal effect of wage growth on unemployment. The research investigates whether these effects are dominated by districts in which unionisation rates are high and employment is concentrated in large firms. Wage growth of middle-paid to highly paid workers – as opposed to low-paid workers – reduces local labour demand and raises local unemployment. Bargaining arrangements correspond closely to the spatial wage distribution; in turn, a large part of the impact that wage growth has on labour market outcomes is determined by these wage-setting institutions.     

Unemployment duration and earnings of re-employed workers in urban China

The recent draconian program of labor retrenchment in China caused widespread unemployment. Many of the retrenched workers remained unemployed for a long time. How did the duration of their unemployment affect their re-employment earnings? The possible relationships between unemployment duration and subsequent wages are modelled heuristically, four explanations for a negative relationship being found. This hypothesis is investigated by means of a survey of workers in 13 Chinese cities, conducted in 2000. Re-employment earnings are found to decline as unemployment continues, an effect that is both statistically significant and quantitatively important. China's displaced workers face a tough labor market.     

Fiscal stimulus and labor market dynamics in Japan

The paper studies the effects of fiscal expansion on the Japanese labor market. First, using a structural VAR model, we find that the unemployment rate falls and employment rises following an increase in government spending. We also find that fiscal expansion affects flows in and out of unemployment. While an increase in government spending increases the job-finding rate, it reduces the separation rate. We then incorporate search and matching frictions into a standard dynamic general equilibrium model, and study whether the model can explain what we observed in data. While the model fails to predict the exact size of the impact of government spending shocks on the Japanese labor market variables, it can consistently capture the empirical pattern of responses of labor market variables to shocks.     

财政分权、经济增长与外贸依存度——基于1978～2007年改革开放30年数据的实证分析

本文以我国1978～2007年的数据,运用协整、Granger因果检验、脉冲响应函数研究了我国财政分权、经济增长对外贸依存度的动态影响。研究发现:长期内,财政分权会推进外贸依存度的提高,而短期内财政分权对外贸依存度的作用不显著;以人均GDP衡量的经济增长,在短期内可提高外贸依存度水平,而在长期中却会降低外贸依存度。分析表明,财政分权引致的地方政府为经济增长而产生的对FDI和出口的激励,以及贸易升级、产业结构调整、内需导向型经济增长模式,是财政分权、经济增长和外贸依存度之间动态关系产生的内在逻辑。     

财政支出、居民消费与经济波动——基于动态随机一般均衡模型(DSGE)的分析

在动态随机一般均衡(DSGE)模型中引入财政支出冲击和居民消费习惯,将财政支出分为生产性支出和消费性支出,分别纳入生产函数和总消费函数,通过DSGE模型模拟了财政支出对居民消费、产出、就业、投资等经济变量的动态影响。模拟结果显示财政支出增加对居民消费产生了挤出效应,而对产出、就业等经济变量产生挤入效应。考虑消费习惯后,经济变量对外生冲击的响应呈驼峰状,并且影响程度加大。因此,合理划分政府支出的类型并恰当评估居民的消费习惯对把握财政政策的操作力度甚为重要。     

FISCAL SUSTAINABILITY AND THE FISCAL REACTION FUNCTION FOR SOUTH AFRICA: ASSESSMENT OF THE PAST AND FUTURE POLICY APPLICATIONS

How does the South African government react to changes in its debt position? In investigating this question, this paper estimates fiscal reaction functions using various methods (ordinary least squares, threshold autoregressive, state‐space modelling and vector error‐correction model). This paper finds that since 1946, the South African government has run sustainable fiscal policy by reducing the primary deficit or increasing the surplus in response to rising debt. Looking ahead, this paper considers the use of fiscal reaction functions to forecast the debt/gross domestic product (GDP) ratio and gauging the likelihood of achieving policy goals with the aid of probabilistic simulations and fan charts.     

Restructuring Indonesia's sub-national public debt: reform or reversion?

Borrowing can be an efficient way for sub-national governments to acquire capital assets, but it also carries risks of fiscal distress and insolvency for borrowers. To minimise these risks, many governments around the world have developed ex-post insolvency remedies, including, most importantly, debt-restructuring mechanisms. In an effort to resurrect borrowing for local infrastructure development, the Indonesian government has designed and begun to implement debt-restructuring programs for sub-national government and sub-national government-owned water supply company defaulters. These programs constitute a major effort to reform an important, long-neglected and problematic aspect of sub-national public finances in Indonesia. There are a number of potential difficulties with the design and execution of the reforms, however, which collectively do not inspire much optimism for rapid progress in reviving financial flows to the sub-national public sector. Still, even halting advances in debt restructuring can substantially increase local infrastructure investment in the long run.     

SDIs: Infrastructure,agglomeration and the region in industrial policy

This article reports on the initial findings of an Industrial Strategy Project Research Programme on a key current element of national industrial policy, namely Spatial Development Initiatives (SDIs). The ISP Research Programme is concerned with industrial investment. The operational industrial SDIs are examined against the backdrops of the pattern of contemporary industrial location in South Africa and the emergence of a regional industrial policy for the country; the long‐run experience with SDI‐type programmes internationally and in South Africa; and directions in current regional industrial development theory and practice, particularly those interventions aimed at strengthening the economies associated with regional/sectoral clusters or agglomerations typically embedded in metropolitan locations. The preliminary findings of research commissioned on long‐run industrial development in Richards Bay, and the current SDI processes under way in the Fish River SDI (Eastern Cape) and the West Coast SDI (Western Cape) are then presented These findings demonstrate that for the SDIs to meet their intentions in terms of maximising inward investment, creating jobs and catalysing durable regional economic development, the large opportunity present to use SDI processes to build the capacity and social infrastructure for economic development at local and regional level on — and between — both public and private sector sides should be grasped. To this end, it is also suggested that SDIs be closely linked to other government industrial promotion and support activities, notably the cluster initiatives and SMME support programmes, both of which may themselves need, at this point, far clearer regional focus.     

On simultaneous explanation of long and medium-term employment cycles

Summary Long and medium-term employment cycles are simultaneously analyzed in a dynamic disequilibrium model, which applies the Goodwin (1951)-type nonlinear accelerator to capital widening and capital deepening investment separately. Capacity utilization and profitability are the variables that control this — purely endogenous — dynamic process. A link is provided between the disequilibrium analysis of unemployment by Malinvaudet al. and nonlinear cycle theories. Different unemployment regimes,i.e. deficient demand, deficient capacity, deficient labor intensity as causes of unemployment, emerge in a dynamic context. Time path and periodicity have a straight interpretation in terms of the behavioral parameters of the model.Two mathematical appendices belonging to section 3 below have been omitted for reasons of space. These are available on request.This article appeared in a preliminary form as a Research Memorandum of the Department of Economics of the University of Amsterdam, No. 8717.

Short and Long Effects of Productivity on Unemployment

Okun’s (1962) seminal paper is an important study on economic growth and unemployment but a detailed exploration of the effect of productivity growth on unemployment has been left aside. Yet, the relationship between productivity growth and unemployment has been debated since long. In this paper we present stylized facts on the link between productivity growth and unemployment for the short and long run, and present model variants that demonstrate that in the short run productivity growth may increase unemployment while in the long run the relationship between productivity growth and unemployment are likely to co-vary negatively. Using US data, empirically we decompose the time series of unemployment rate and productivity growth into long run and short run components and show empirical evidence that the long run and short run components co-vary as predicted by some theories.     

An integrated planning model for investment in urban infrastructure and pricing municipal services

This viewpoint proposes an iterative, cyclical and incremental model for preparing and pricing a capital investment programme and budget for municipal infrastructure services. South African towns and cities are used as case‐studies. The model links capital investment, operation and maintenance (supply) to the prices offered or paid by the beneficiaries (demand). Ignoring the conventional framework for the development of an area, this viewpoint concentrates on how capital investment for municipal infrastructure services could be planned and programmed and prices or tariffs determined. Given that socio‐economic trends in most municipalities in South Africa are unpredictable, short‐ to medium‐term capital investment planning is emphasised.
