未被观测经济与居民收入不平等——基于中国省级面板数据的实证研究

未被观测经济（NOE）对经济发展具有诸多影响,但对居民收入不平等的影响尚未引起足够重视。文章基于动态均衡解的劳动报酬模型得到,随着NOE规模扩大,收入不平等程度（即劳动者从事NOE部门的报酬与从事可观测部门的报酬之差）呈现单调递增的变化过程,但边际变化率先增后减。当考虑劳动者决策的随机动态调整因素时,NOE规模与收入不平等之间存在高低两个动态变化均衡点。在该模型基础上,基于2000-2010年中国省级面板数据,证实了NOE规模与居民收入不平等之间存在显著正向影响关系,人力资本水平、市场化程度和腐败水平也与居民收入不平等呈正向影响关系,而城市化水平则呈较显著的负向影响关系。基于实证结果,提出了相关的政策建议,并对未来研究方向进行展望。     

中国式分权、转移支付与居民收入不平等

本文首先采用基尼系数对我国城乡、城镇和农村居民收入不平等程度进行重新测度,然后以政府转移支付为门限变量建立面板门限回归模型,对财政收支分权与居民收入不平等之间关系进行实证检验,结果发现:一是财政收入分权与收入不平等显著负相关,财政支出分权与收入不平等显著正相关;二是财政收支分权对不同类型收入不平等的作用效果存在较大差异.其中,无论是财政收入分权抑或支出分权对收入不平等的政策效应大小依次是城镇居民＞农村居民＞总体居民;三是政府转移支付在不同区制对居民收入不平等的影响呈现显著地非线性特征.即从相对较低的第一区制跨入较高的第二区制时,转移支付对居民收入不平等的影响由负转变为正.本文以上研究结论不仅对于全面构建央地新型政府间财政关系,还可以为促进公平收入分配提供理论依据与决策参考.     

The impact of monetary and tax policy on income inequality in Japan

This paper assesses the effects of the most recent monetary policy behaviour of the Bank of Japan (in particular, zero interest rate policy and negative interest rate policy) and Japanese tax policy on income inequality in this country during the period of 2002Q1 to 2017Q3. The vector error correction model (VECM) that develops in this research shows that increase in money stock (m1) through Quantitative Easing (QE) and Quantitative and Qualitative Easing (QQE) policies of the BOJ significantly increases the income inequality. On the contrary, Japanese tax policy was effective in reducing the income inequality. Variance decomposition results show that increasing of income inequality by monetary policy is larger when comparing to decreasing effects of tax policy on income inequality. Cointegration and VECM results show that monetary policy has both short-run and long-run impacts but for tax policy paper could not find any significant short-run impact on income inequality. In addition, paper found that technological progress only in long-run can reduce the income inequality by increasing the marginal productivity of labour with positive impacts on employment and wages.     

城乡收入差距与经济增长关系的实证研究——基于中国1978—2007年数据的协整检验与脉冲响应分析

对中国1978—2007年数据的实证研究结果表明：城乡收入差距与经济增长之间存在着长期稳定的双向因果关系：城乡收入差距只在短期内对经济增长产生影响;而经济增长并不会自动导致城乡收入差距的缩小,相反,经济增长在中长期内还会进一步加大城乡收入差距。     

收入不平等对经济增长的负面影响机制——近二十年文献综述

近年来,国内外学者运用各种方法探讨了收入不平等与经济增长的关系。大部分研究结论显示,收入差距对经济增长存在间接的负面影响,两者之间存在一个多因素的传导过程,包括人力资本积累机制、政治经济决策机制、社会冲突机制、需求传导机制以及其他传导机制。总的来看,这些研究加深了对于两者关系性质和相互影响的认识,但研究结论的分歧和研究方法的局限性仍然存在,有必要对两者关系进行更深入的研究。     

财政分权对中国环境治理绩效的合意性研究——基于系统GMM及门槛效应的检验

文章选择2007-2016年30个省（市、自治区）的面板数据，采用系统GMM和门槛效应模型探讨财政分权对环境治理绩效的影响。结论表明：从系统GMM检验来看，财政分权对环境治理绩效具有显著的负向抑制作用，并呈现出地区差异性，其中，东部表现为正向促进，而中西部表现为负向抑制。从门槛效应来看，财政分权对环境治理绩效存在显著的单一门槛效应。其中，自有收入分权表明，不论其分权化水平高低，均产生负向抑制作用；收入分权表明，在分权化水平较低时，产生负向抑制作用，在分权化水平较高时，抑制作用不显著；支出分权表明，在分权化水平较低时，抑制作用不显著，在分权化水平较高时，产生负向抑制作用。最后，依据实证结论得出相关政策启示。     

Wage-led versus profit-led demand: A comprehensive empirical analysis

This study investigates various economic factors’ impact in determining the relationship between functional income distribution and aggregate demand from both a theoretical and an empirical viewpoint. We base our analysis on a demand-driven growth model for an open economy that allows for either profit-led or wage-led regimes. Our results strongly indicate that a higher level of trade openness is associated with a lower probability of being wage-led. We find evidence that lower wage inequality makes an economy more wage-led and that countries with a greater private credit-to-gross domestic product (GDP) ratio are more likely to be profit-led.     

Does foreign direct investment really enhance China's regional productivity?

While foreign direct investment (FDI) is widely recognized as one of major driving forces on promoting the regional economic growth in China, its impact on regional productivity is unclear and less systematically investigated. This article investigates the effect of FDI on regional productivity in China. Specifically, we adopt a newly developed measure of total factor productivity (TFP) to deal with the endogenous inputs choice accompanied with various measures of FDI, enabling to provide robust estimates on the TFP effect of FDI. Moreover, we examine the role of absorptive ability on the FDI-TFP nexus and explore the existence of FDI spillover effect on productivity across regions. The potential difference in productivity effect of FDI between coastal and non-coastal regions is also examined. Based on the province-level panel dataset over the period 1997–2006, the various estimates show that the overall productivity effect of FDI is significantly positive, while this effect depends heavily on the host region's absorptive ability. Technological gap is found to associate with a significantly negative coefficient along with the finding that FDI tends to exhibit a higher impact on productivity in coastal regions than their non-coastal counterparts, highlighting a widening income inequality between coastal and non-coastal regions in China.     

Foreign Exchange Reserves and Import Demand: Evidence from Latin America

This paper investigates the impact of foreign reserves, domestic real income and relative import prices on import demand for seven Latin American countries. We differentiate empirically between the short‐run and long‐run impact of reserves, income and prices on imports. The paper has three main results. First, we show that there exists a unique long‐run relationship among real imports, real income, relative import prices and real foreign exchange reserves for all seven countries. Second, we find that increases in foreign exchange reserves exert a significant positive effect on import demand in both the long run and the short run in all countries. However, the economic impact of foreign exchange reserves is rather small. Finally, we find that the long‐ and short‐run impact of real domestic income on import demand is positive as well, while the effect of relative prices is negative.     

Skill classification does matter: estimating the relationship between trade flows and wage inequality

Empirical work must pay careful attention to how it measures the relative skill abundance of countries and the relative skill intensity embodied in trade flows. This paper compiles a new data set, using income levels, average education, manufacturing wages, and an index of these three variables, to classify countries and trade flows as relatively high skill or low skill. Then, in order to show the importance of skill classification, it uses a reduced-form fixed-effects model to estimate the relationship between trade flows and wage inequality. This specification not only controls for any time-invariant omitted variables, but also permits the inclusion of a large number of diverse countries. When more accurate skill rankings are utilized, results suggest that, in high-skill abundant countries, increased trade with lower-skill countries is correlated with an increase in wage inequality. This relationship is significant and highly robust and is driven by the negative relationship between trade and low-skill wages (instead of a positive relationship between trade and high-skill wages.) Results, however, are highly dependent on the skill classification utilized.     

经济开放与收入差距:基于STR模型的分析

基于1978—2009年的时间序列数据,在总结相关传导机制的基础上,运用平滑转换回归模型就经济开放对收入差距的影响效应进行研究。结果表明:中国经济开放与收入差距之间的关系是非线性的,两者之间存在明显的体制转换动态特征。在1985年以前,经济开放对收入差距的效应为负;在1985年以后,经济开放对收入差距的效应为正。主要原因在于,经济地理效应和技术偏移效应逐渐替代了要素禀赋效应。     

中国城乡劳动力流动影响因素研究——理论模型与实证分析

结合中国实际情况,对哈里斯-托达罗模型的基本假设进行修定,从农民追求预期净收益现值最大化出发,运用动态宏观经济学的递归方法,推导出均衡条件下中国城乡劳动力流动影响因素的理论模型,并采用动态面板计量方法实证检验各影响因素对城乡劳动力流动的作用方向和程度。研究发现：城乡劳动力流动率的滞后值、城乡实际收入差距、非农产值比和农业比较劳动生产率对城乡劳动力流动有正的影响,但城乡实际收入差距的影响系数值偏小;城镇失业率、城乡消费支出比和农村工业化对城乡劳动力流动有负的影响;制度变迁和全社会固定资产投资率对城乡劳动力流动也有一定程度但不显著的正影响。为了解决农民工就业问题,应加强城乡联动共同发展。     

Productivity spillovers from foreign direct investment: evidence from Turkish micro-level data

This paper analyzes the productivity spillovers from foreign direct investment (FDI) using Turkish firm-level data for a more recent time period, 2003–2010, which coincides with significant FDI inflows both in manufacturing and service sectors in the region. The empirical model is derived from endogenous growth theory whereby the rate of technological progress is partly determined by technology transfers and spillovers from international contacts, our exclusive focus being on FDI-induced spillovers. The impact of FDI onto the firm-level productivity is evaluated via the channels of horizontal and vertical linkages. The empirical results show that horizontal linkages decrease the productivity of firms, whereas vertical linkages exert a positive impact onto the local productivity levels, thereby drawing attention of policy makers towards strengthening of supplier–buyer relationship between local and multinationals in order to optimize the benefits from FDI. This study also acknowledges the heterogeneity of local (foreign) firms and their differential capacity to absorb (exude) the FDI-induced externalities.     

中国对日农产品出口的增长因素研究 ——基于CMS 模型的实证分析

日本是中国农产品出口的主要对象国,两国贸易关系相当密切。本文采用CMS模型对中国农产品出口日本市场的增长因素进行实证研究得出:中国输日农产品增长主要由日本国内市场需求增长所引致;产品结构效应对中国农产品输日增长具有显著的正向影响,而综合竞争力效应和产品竞争力效应对中国农产品输日增长产生阻碍作用。为扩大中国农产品对日出口,本文针对不同影响因素提出相应的对策建议。     

Who's afraid of a globalized world? Foreign Direct Investments, local knowledge and allocation of talents

We study the distributional effects of globalization within a model of heterogeneous agents where both managerial talent and knowledge of the local economic environment are required in order to become a successful entrepreneur. Agents willing to set up a firm abroad incur a learning cost that depends on how different the foreign and domestic entrepreneurial environments are. In this context, we show that globalization fosters FDI and raises wages, output and productivity. However, not everybody wins. The steady state relationship between globalization and income is U-shaped: high- and low-income agents are better off in a globalized world, while middle-income agents (domestic entrepreneurs) are worse off. Thus, consistently with recent empirical evidence, the model predicts globalization to increase inequality at the top of the income distribution while decreasing it at the bottom.     

An empirical analysis of the relationship between entrepreneurship and income inequality

The paper estimates the relationship between entrepreneurship and income inequality. Using US state-level data for the period 1989 to 2013, and the system generalized method of moments (GMM) estimator, we find a significant positive relationship between entrepreneurship and income inequality. This finding is generally robust across alternative measures of inequality and entrepreneurship.     

Informality,tariffs and wealth

This article analyzes the interaction between changes in tariff protection, informality, inequality and aggregate income. First, we describe some new empirical evidence on informality, the formal/informal wage gap and trade openness in Latin American countries. Then we present a simple model characterized by three (empirically based) assumptions: (1) agents consume both formal and informal goods; (2) the government uses tariff revenues to purchase formal goods; (3) informality is a voluntary phenomenon. The model predicts that tariff reduction increases informality and wage inequality and that the maximization of income requires a positive level of tariff protection. The model's results are shown to be consistent with the empirical evidence concerning Latin American countries.     

INNOVATION AND GROWTH WITH RICH AND POOR CONSUMERS

This work studies the impact of income inequality on the level of innovative activities in a model where innovations result in quality improvements. In contrast to the standard model of innovations and growth, the equilibrium outcome may be characterized by a situation where not only the quality leader but also producers of worse qualities are on the market. In that case the quality leader sells to the rich, whereas the producer of the second‐best quality sells to the poor. In general, we find that a more equal distribution of income is favourable for innovation incentives. This is consistent with empirical evidence suggesting that countries with a more equal distribution of income have grown faster.     

Functional income distribution,capacity utilization,capital accumulation and productivity growth in Turkey: A post-Kaleckian analysis

The aim of this article is to examine the relation between functional income distribution, capacity utilization, capital accumulation and productivity in Turkey by identifying demand and overall regimes prevalent in the economy. For this purpose, we conducted an empirical analysis using different specifications of the post-Kaleckian model of Hein and Tarassow. This model defines and characterizes an overall regime by endogenizing productivity growth and integrating it into the models in this tradition. Empirical findings show that while the demand regime is wage-led, the overall regime turns out to be unstable in Turkey due to the destabilizing impact of productivity growth. This article contributes to the literature by being the first study that simultaneously identifies the demand and the overall regimes of an economy.     

Globalisation and Economic Growth: A Historical Perspective

This paper reviews the historical evidence on the relationship between globalisation and economic growth. Divergence in the growth of income and industrialisation in the twentieth century is documented but it is also noted that international income inequality appears to have decreased since about 1870 and that long-run trends in the Human Development Index are much less pessimistic about the experience of developing countries. It is argued that trade liberalisation has been good for growth on average but that successful capital liberalisation requires high institutional quality and that the developmental state may have an important role to play in the early stages of development. The recent claim by Robert Lucas that the 21st century will see a massive reduction in income inequality across countries in a globalised world economy is sceptically discussed in the context of empirical evidence that bad institutions are often persistent and that geography is still a major factor in explaining international income differences.
