Pre-commitment Mechanism and Policy Credibility in African Trade Reform

In the absence of a binding pre-commitment mechanism, a government has an incentive to renege on announced policy. This is a well-established result in the literature. The paper applies this theory to tariff policy by developing a two-game model to analyze the credibility of government tariff reform announcements. The pre-commitment solution is subgame-imperfect; therefore, government's announcement of tariff reforms is time-inconsistent. Using a sample of African countries operating under IMF structural adjustment programs, the study finds only weak evidence that countries implemented their announced tariff reforms. However, SAP agreements seem to enhance private sector confidence in government reforms.     

关税减让政策对我国进口的影响

中国加入WTO后,关税减让协议的逐步实行对我国进口贸易产生了极大影响.研究结果表明,关税与我国进口贸易额之间存在着高度的负相关关系,在影响我国进口效应的诸多因素中.关税起到了主要作用,但并非唯一因素.而关税减让在影响我国进口商品结构方面的作用不大.可见,在优化我国进口商品结构方面还需要其他政策措施的辅助与调整.     

UNEMPLOYMENT, HYSTERESIS AND TRANSITION

In this paper, we quantify the degree of persistence in the unemployment rates of transition countries using a variety of methods benchmarked against the EU. Initially, we work with the concept of linear ‘Hysteresis’ as described by the presence of unit roots in unemployment as in most empirical research on this area. Given that this is potentially a narrow definition, we also take into account the existence of structural breaks and nonlinear dynamics in unemployment. Finally, we examine whether CEECs' unemployment presents features of multiple equilibria, that is, if it remains locked into a new level whenever some structural change or sufficiently large shock occurs. Our findings show that, in general, we can reject the unit‐root hypothesis after controlling for structural changes and business‐cycle effects, but we can observe the presence of a high and low unemployment equilibria. The speed of adjustment is faster for CEECs than the EU, although CEECs tend to move more frequently between equilibria.     

Factors of Immobility: Why the Unemployment Rate is Slow to Adjust

During the recent recession and the continuing recovery, the national unemployment rate has maintained a level that has only been observed one other time since the Great Depression. While the initial causes of the increased unemployment rate are documented, the adjustment process and reduction of unemployment rates back toward some natural rate has not been addressed empirically. In this paper, the authors analyze labor supply side factors that may cause unemployment rates to remain high for a longer period than the typical recession. The authors focus on the impact of unemployment insurance extensions, housing market contractions and the general breadth of the economic downturn as factors that slow the labor supply adjustment process and lead to prolonged high rates of unemployment.     

美国碳关税政策对中美贸易的影响

基于环境保护和贸易保护的目的,美国提出了征收碳关税诉求。这将对中国对美国的商品出口产生什么样的影响?本文根据我国各行业的碳排放强度和出口贸易细分数据,分析了美国征收碳关税可能会对我国各行业出口贸易的影响,并提出,中国应该在多边贸易组织的框架下对美国将实行的碳关税政策进行限制约束,及时调整国内产业结构。     

Trade Liberalization and Firm Productivity: Evidence from Chinese Manufacturing Industries

This paper examines the impact of tariff reduction following China's World Trade Organization (WTO) entry on the productivity of Chinese manufacturing firms using a firm‐level panel database that comprises all of China's manufacturing firms with an annual turnover above 5 million yuan and that spans the period of 2000–2006. An instrumental variable estimator is used to account for the endogeneity of the tariff reduction. The results indicate that China's trade liberalization in the five years following its WTO entry has led to a 0.94% annual increase in total factor productivity for Chinese manufacturing firms. However, the overall productivity gain from the tariff reduction is a net result of a productivity depressing effect of output tariff reduction and a productivity enhancing effect of input tariff reduction. Both effects have diminished in magnitude over the years after China joined the WTO. Firm heterogeneity and turnover plays an important role in generating gains from trade liberalization. The surviving firms have managed to cope with and take advantage of lower tariffs. The extent to which the tariff reduction affects Chinese firms' productivity is also dependent on the ownership structure of the firms with foreign‐invested firms being the clear winner.     

基于税制优化的结构性减税政策研究

结构性减税是本轮积极财政政策的重头戏,自2008年底以来,结构性减税政策在保增长、调结构与扩内需的反周期操作中一度扮演积极的角色。我国结构性减税政策的操作遵循宏观调控与税制优化两种不同的范式,宏观调控范式侧重总量均衡的短期相机抉择,税制优化范式注重结构调整的长期制度安排。后金融危机时代,基于宏观调控的结构性减税将日趋淡出,基于税制优化的结构性减税应坚持结构性减税与税制优化相结合,结构性减税与结构性增税相结合,结构性减税与配套改革相结合。     

我国结构性失业的类型与对策

结构性失业逐渐成为我国失业问题的主要方面,研究结构性失业的类型有助于更好地解决我国的失业问题。我国结构性失业大体可以分为市场型结构性失业、制度型结构性失业和观念型结构性失业,前者又分为供给滞后型结构性失业、需求变动型结构性失业和机制不灵型结构性失业。根据不同的结构性失业类型,应采用有针对性的解决对策。     

Persistent unemployment and co-ordination issues: an evolutionary perspective

Abstract. In this paper we look at unemployment as a phenomenon which reflects the co-ordination problems that characterize out-of-equilibrium processes of adjustment. The analysis carried out shifts the focus from structural factors to the economic process. It shows that unemployment cannot be satisfactorily explained – and policy interventions devised – by focusing only on specific characters of the technology or confining the analysis to structural factors concerning the labour market. The co-ordination mechanisms of adjustment processes rather than the fundamentals of the economy appear, in this light, as the main determinants of differences in unemployment trends in different economies; and monetary policy comes back to the center of the stage as an essential element of the working of these mechanisms.

Economic liberalization and welfare in a model with an informal sector

The paper reexamines the conventional results relating to inflow of foreign capital, removal of protectionism and structural reform programmes, in a small open economy in terms of a two-sector general equilibrium model with an informal sector. The paper shows that in the presence of labour market distortion and a protectionist policy, inflow of foreign capital may be desirable irrespective of the pattern of trade of the economy due to its favourable impact on welfare. But the welfare implications of tariff reductions and/or structural adjustment programmes, such as deregulating the formal sector labour market, depend crucially on the economy's trade pattern. The paper provides an answer to the question as to whether in a developing economy labour market reform and tariff reform should go hand-in-hand or whether one should precede the other for welfare improvement.

The impact of trade openness on labour force participation rate

In this article, we investigate the impact of trade openness on labour force participation rate. We use tariff rate as the main indicator of trade openness and we employ the number of regional trade agreements and the average tariff rate in the neighbours’ countries as instrumental variables to diminish the endogeneity problem of the tariff rate. We find that trade openness increases the participation rate which is economically and statistically significant. The results show that this correlation is robust under controlling for different variables and using various specifications. We find that 10 percentage point increase in tariff rate lowers the participation rate by 4–6 percentage point and this relationship is more severe in the long run. Finally, we show that changes in labour force population accounts for about 27% of changes in the unemployment rate following a trade liberalization.     

碳关税对我国国际收支"双顺差"的影响

碳关税的全面实施会通过净出口渠道和长期资本流入渠道影响到我国的国际收支:其中,经常账户收支差额减少有限,不会改变其顺差格局;资本金融账户收支差额会大幅度变化,其顺差地位可能发生扭转。因此,碳关税实施有利于我国当前国际收支双顺差的调节;但为了避免碳关税对资本金融账户的过度冲击,我们在当前应一方面积极引导FDI投资领域的转向,提升外资质量;另一方面积极推动加工贸易的技术升级,推动生产方式的绿色化转型。     

Foreign-Investment Tax and Tariff Policies in Developing Countries

In this paper we examine the welfare effects of tax on foreign capital and tariff policies for a small open economy with sectoral unemployment. The individually and jointly optimal tax and tariff rates in the absence or presence of international tax credits are derived. A subsidy on foreign capital coupled with a tariff can be jointly optimal when tax credits are absent in the source country. However, the capital subsidy policy may fail to hold when the foreign country follows a tax credit system.     

Convergence in West German Regional Unemployment Rates

Abstract. Differences in regional unemployment rates are often used to describe regional economic inequality. This paper asks whether changes in regional unemployment differences in West Germany are persistent over time. Understanding the persistency of regional unemployment differences helps us to assess how effective regional policy can be. While univariate tests suggest that changes in regional unemployment differences are persistent in West Germany, more powerful panel tests lend some support to the hypothesis that regional unemployment rates converge. However, these tests reveal a moderate speed of convergence at best. Because there is a structural break following the second oil crisis, we also use tests that allow for such a break. This provides evidence for both convergence and quick adjustment to an equilibrium distribution of regional unemployment rates that is, however, subject to a structural break.     

Does Inflation Grease the Wheels of Adjustment? New evidence from the US economy

This paper presents a new interpretation of the Phillips curve that rests on the process of nominal wage adjustment in a multi-sector economy. Nominal demand growth causes inflation in sectors with full employment, but it speeds up the process of employment creation in sectors with unemployment. As a result, demand-pull inflation is associated with both a reduction in the duration of unemployment and the economy wide average rate of unemployment. The paper provides empirical evidence from the US economy consistent with this claim.     

HYSTERESIS HYPOTHESIS IN UNEMPLOYMENT AND LABOUR FORCE PARTICIPATION RATES: EVIDENCE FROM AUSTRALIAN STATES AND TERRITORIES *

This article simultaneously investigates the hysteresis hypothesis of unemployment and labour force participation using regional level data in Australia. The conventional univariate and panel unit root tests indicate that the hysteresis hypothesis cannot be rejected for most of the regions in Australia. To further confirm if the hysteresis finding in unemployment and labour force participation results from not considering structural breaks. We employ a panel stationarity test recently developed by Carrion‐i‐Silvestre et al. (2005 ), which considers multiple structural breaks and cross‐sectional dependence. The test results lend support for unemployment hysteresis and participation regime‐wise stationarity. Accordingly, the findings imply that a temporary shock may have permanent effects on the unemployment rate but not on labour force participation in Australia and thus call for policies aimed at improving the adjustment mechanism in unemployment.     

价格粘性下人民币不同升值模式对中国经济的影响研究

文章以衰减函数的方式将新凯恩斯学派提出的价格粘性理论引入中国动态可计算一般均衡模型中,使模型更符合经济系统中价格调整规律,并利用模型模拟渐进式升值和快速升值两种不同的人民币升值模式对我国经济的影响。模拟结果表明,在价格粘性的作用下,人民币快速升值将在短期内对我国实体经济产生较大的负面冲击,GDP增速下降最高达1.6个百分点,失业率明显上升,而渐进式升值最高只有0.67个百分点;快速升值能有效抑制我国的通货膨胀和促使我国贸易再平衡,最多使我国CPI增速下降3.6个百分点和贸易顺差占GDP比重下降1.06个百分点,并且在长期内对实体经济的负面效应略小于渐进式升值。因此,在不同的经济形势下应采取不同的人民币升值模式。     

中国的就业问题及其对策

在未来的十几年,中国将面临严峻的总量性失业和结构性失业问题。总量性失业和结构性失业都会扩大城乡收入差距,不利于社会的安定团结和长期增长。结构性失业阻碍产业结构的升级和城乡二元经济结构的消除,从而不利于我国经济的长期增长。除了人口基数大之外,赶超战略是我国总量性失业和结构性失业的最主要原因。最后,本文提出了长期和短期的政策建议。
