我国收入分配差距及个人所得税调节作用的实证分析

本文通过计算我国城镇居民税前收入、税后收入和税收收入的基尼系数，计算各个收入阶层的平均税率及建立计量经济模型等多角度分析了个人所得税对城镇居民收入分配差距的调节作用。最后得出结论：目前我国收入分配差距仍呈扩大趋势，但没达到两极分化的程度，2002年以来个人所得税逐渐发挥对收入分配差距的调节作用。对高收入阶层课以重税，同时增加低收入阶层的可支配收入，是改善目前收入分配不平等状况行之有效的措施，税收政策和其他社会保障的收入分配政策相结合，可以对缩小收入分配差距，建立社会主义和谐社会起到更大的作用。     

Trade and the distribution of human capital

We develop a two-country, two-sector model of trade where the only difference between the two countries is their distribution of human capital endowments. We show that even if the two countries have identical aggregate human capital endowments the pattern of trade depends on the properties of the two human capital distributions. We also show that the two distributions of endowments also completely determine the effects of trade on income inequality. We also look at a simple majority voting model. It turns out autarky and free trade with and without compensation may be the voting outcome.

Trade liberalization in asian newly industrialized countries

Singapore, South Korea, and Taiwan are often perceived as having achieved similar trade patterns; nevertheless, their trade policies and patterns differ in fundamental respects. In this study, three models are considered and different aspects of the trade liberalization policies of these three countries are highlighted. The model of South Korea underscores the significance of product market concentration in restraining real wage growth and contributing to income inequality. The model of Singapore highlights the role of foreign investment in producing manufactured goods for export and in raising real wages. The factor proportions model of a labor-abundant economy adequately describes the Taiwanese liberalization. The model's predictions of rising real wages and no monopoly profits are consistent with Taiwan's declining income inequality.     

贸易对收入分配影响研究的最新进展及其评论

随着近年来保护贸易的盛行与收入差距持续扩大,国际贸易对收入分配的影响成为国际经济学领域的研究热点。本文从国际贸易对一国整体收入水平以及国内收入差距的影响两个角度介绍了近年来这方面理论的最新进展及趋势。尽管各理论分析角度、模型设计以及数据运用各不相同,但结论趋于一致,即自由贸易会带来一国整体收入的提高,但也会导致收入差距的扩大,因此保护贸易政策会损害到一国整体福利,自由贸易导致收入差距的扩大可通过适当国内再分配政策进行调节。     

Pro-poor trade policy in Sub-Saharan Africa

This paper examines the presence of a pro-poor bias in the existing structure of protection of six Sub-Saharan African (SSA) countries, Burkina Faso, Cameroon, Côte d'Ivoire, Ethiopia, Gambia, and Madagascar. We build on a simple agricultural household production model and we propose an extension to include adjustments in labor income. Our approach, which can be implemented without repeated cross-sections of household level data, suits well the data constraints in SSA. It also allows us to capture the heterogeneity in trade protection at the tariff line level. The pro-poor bias indicators suggest that SSA's trade policies tend to be biased in favor of poor households, as these policies redistribute income from rich to poor households. This is because protection increases the agricultural prices of goods that are sold by African households and this effect dominates both the impacts of higher consumption prices and the strong Stolper–Samuelson effects that benefit skilled over unskilled workers.     

Top income shares in OECD countries: The role of government ideology and globalisation

This paper investigates how government ideology and globalisation are associated with top income shares in 17 OECD countries over the period 1970 to 2014. We use top income shares of the World Wealth and Income Database (WID ). Globalisation is measured by the KOF index of globalisation. Static and dynamic panel model results show that the top income shares increased more under right wing governments than under left wing governments. The ideology‐induced effect was stronger when globalisation proceeded more rapidly. Globalisation was positively correlated with income shares of the upper‐middle class (P99–P90), but negatively with income shares of the rich (top 1%) in the overall sample. We show that the relationship differs between Anglo‐Saxon countries and other OECD countries. Globalisation was more pro‐rich in Anglo‐Saxon countries than in other OECD countries. Government ideology does not turn out to have a statistically significant effect on top income shares in Anglo‐Saxon countries after the 1980s, whereas ideology‐induced differences in the distributional outcomes continued in other OECD countries.

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.     

Openness,inequality and poverty: Endowments matter

Using tariffs as a measure of openness, this paper finds consistent evidence that the conditional effects of trade liberalization on inequality are correlated with relative factor endowments. Trade liberalization, measured by changes in tariff revenues, is associated with increases in inequality in countries well-endowed with highly skilled workers and capital or with workers that have very low education levels. Similar, although less robust, results are also obtained when decile data are used instead of the usual Gini coefficients. Taken together, the results are strongly supportive of the factor-proportions theory of trade and suggest that trade liberalization in poor countries where the share of the labor force with little education is high raises inequality. Simulation results also suggest that relatively small changes in inequality as measured by aggregate measures of inequality, like the Gini coefficient, are magnified when estimates are carried out using decile data.     

DETERMINANTS OF TRADE: THE CASE OF MEXICO

This article explains the extent of intra-industry trade (IIT) in Mexico's foreign trade, and tests empirically various country-specific hypotheses concerning the determinants of intra-industry trade between Mexico and its major trading partners. The results of the econometric analysis corroborate the predictions of the theoretical models. The results indicate that the extent of Mexican intra-industry trade is positively correlated with the average income levels, average country size, trade intensity, trade orientation, the existence of a common border, the existence of a common language, and the participation in regional integration schemes, while it is negatively correlated with income inequality, inequality in country size, distance, and trade imbalance.     

Trade, wages, and the political economy of trade protection: evidence from the Colombian trade reforms

Worker industry affiliation plays a crucial role in how trade policy affects wages in many trade models. Yet, most research has focused on how trade policy affects wages by altering the economy-wide returns to a specific worker characteristic (i.e., skill or education) rather than through worker industry affiliation. This paper exploits drastic trade liberalizations in Colombia in the 1980s and 1990s to investigate the relationship between protection and industry wage premiums. We relate wage premiums to trade policy in an empirical framework that accounts for the political economy of trade protection. Accounting for time-invariant political economy factors is critical. When we do not control for unobserved time-invariant industry characteristics, we find that workers in protected sectors earn less than workers with similar observable characteristics in unprotected sectors. Allowing for industry fixed effects reverses the result: trade protection increases relative wages. This positive relationship persists when we instrument for tariff changes. Our results are in line with short- and medium-run models of trade where labor is immobile across sectors or, alternatively, with the existence of industry rents that are reduced by trade liberalization. In the context of the current debate on the rising income inequality in developing countries, our findings point to a source of disparity beyond the well-documented rise in the economy-wide skill premium: because tariff reductions were proportionately larger in sectors employing a high fraction of less-skilled workers, the decrease in the wage premiums in these sectors affected such workers disproportionately.     

Endogenous trade policy through majority voting: an empirical investigation

The median-voter approach to trade policy determination (within a Heckscher-Ohlin framework) as in Mayer [Am. Econ. Rev. 74(5) (1984) 970] predicts that an increase in inequality, holding constant the economy’s overall relative endowments, raises trade barriers in capital-abundant economies and lowers them in capital-scarce economies. We find support for this prediction using cross-country data on inequality, capital-abundance and diverse measures of protection. We perform certain robustness checks that include controlling for the effects of political rights and schooling as well as using alternative datasets on factor endowments.     

Urban development,excessive entry of firms and wage inequality in developing countries

This paper examines the short and long-term effects of urbanisation, via favourable urban development policies, on income distribution and social welfare for a developing country, in which the urban manufacturing sector is characterised by imperfect competition and free entry. Urbanisation shifts rural workers to the highly productive urban sector, while causing production in urban firms to expand because of scale economies. However, urbanisation may worsen wage inequality between skilled and unskilled labour in the short term. In the long term, urbanisation can attract new firms to the urban sector and favourable urban development policies may result in excessive entry of firms, which can amplify wage inequality in the economy. This entry-amplifying effect is confirmed empirically, especially for low and lower-middle-income countries. If the entry effect is not considered, the impact of urbanisation on wage inequality could be understated by 13% for low and lower-middle-income countries.     

Unpacking sources of comparative advantage: A quantitative approach

This paper develops an approach for quantifying the importance of different sources of comparative advantage, by extending the Eaton and Kortum (2002) model to predict industry trade flows. In this framework, comparative advantage is determined by the interaction of country and industry characteristics, with countries specializing in industries whose production needs they can best meet with their factor endowments and institutional strengths. I estimate the model parameters using: (i) OLS; and (ii) a simulated method of moments procedure that accounts for the prevalence of zeros in the bilateral trade data. I apply the model to explore various quantitative questions, such as how much distance, Ricardian productivity, factor endowments, and institutions each matter for country welfare in the global trade equilibrium.     

对外开放与发展中国家的收入不平等:基于亚洲和拉美国家的比较研究

本文基于要素禀赋理论,在将劳动力划分为低、中、高技能三类的基础上,选取亚洲和拉丁美洲部分发展中国家1960-2005年的数据,建立非平衡面板模型,分析两地区的开放对国内收入分配的影响。实证结果表明,亚洲和拉丁美洲发展中国家的对外开放确实对国内收入不平等起到推动作用。目前的开放有利于中等技能劳动力相对丰裕的发展中国家,而不利于低技能劳动力相对丰裕的国家。总体的贸易依存度对拉美不平等的推动作用更大,但外资对亚洲不平等的推动作用更大;制造业出口倾向于扩大拉美国家的收入差距而缩小亚洲国家的收入差距。     

International Inequality and the COVID-19 Pandemic

The lockdowns and stimulus programmes that governments have adopted to fight the COVID-19 pandemic and the associated economic crisis have affected the distribution of income and production within and between countries. Considering both, current evidence indicates that the EU-wide and global inequality of disposable income did not change dramatically in 2020. However, the unequal impact on the wealth and health of people is likely to worsen income inequality in the future.

     

企业所得税税负归宿与收入分配

企业所得税对收入分配具有重要影响,本文将企业所得税税负归宿问题内生化来研究其对收入分配的影响,使用2010年的数据研究企业所得税的税负归宿发现,相对于国家实际征得的企业所得税,资本要素承担了超过100%的税收负担,而劳动要素在我国企业所得税的税负归宿中受益;在收入分配方面,企业所得税具有一定的累进性,能够减少城乡之间、城乡不同收入群体之间的收入分配差距.本文的研究表明,企业所得税对不同收入群体收入的影响大体呈倒U字型分布,因此,降低企业所得税虽然可能导致收入分配进一步恶化,但有利于提高最低收入阶层收入占国民总收入的比重;提高企业所得税虽然有利于调节收入分配,但应注意配合其他措施提高低收入者收入.     

Ungleichheit: Wahrnehmung und Wirklichkeit – ein internationaler Vergleich

Based on a cross-national comparison, there is virtually no empirical relationship between the actual size of income inequality within a country and how critically people view these income differences. This finding is revealed by subjective inequality data on 23 European countries and the US. Instead, views on income distribution can be far better explained by the subjective perception of inequality within a society. Similarly, redistributive preferences are less influenced by actual distribution than by perceived inequality.     

论中国耕地保护制度创新:一个基于区域协调发展的视角

耕地保护是事关中国粮食安全以及社会经济可持续发展的重大课题,为此,政府一直致力于通过世界上最严格的制度及政策措施保护耕地。但问题是,由于各地的工业化和城市化程度不同,其产业结构和社会经济发展也极不均衡,显然,政府绝不可能在全国范围内用统一的政策标准来衡量各地的耕地保护状况。因此,政府可以立足于区域优势以及利益互动等方式来实现耕地保护目标,这不仅符合市场经济体制的基本要求,也有助于实现耕地总量控制、发挥区域经济产业优势以及区域协调发展的统一。在市场经济条件下,政府可以通过构建区域利益互动机制来实现中国耕地保护制度的创新。
