中国农村特色扶贫开发道路的制度分析：基于产权的视角

研究目标：借鉴马克思及西方产权理论主要思想,研究揭示中国农村特色扶贫开发道路的制度选择及经验。研究方法：基于产权理论对经济事实进行逻辑推演,并采用1978~2012年中国农村统计数据进行检验。研究发现：中国农村特色扶贫开发道路主要体现在农村资源（土地和人力）的产权制度改革上,由此形成的资源产权激励效应和正向扩散效应,正是中国农村人口发生大规模减贫的最重要原因及主要经验,并构成了中国特色社会主义制度的一部分。研究创新：本文基于产权理论的研究为减贫提供一个新的微观制度视角解释。研究价值：总结提炼中国农村特色扶贫开发道路的一般性理论经验,对今后减贫事业推进具有借鉴意义。     

社会资本、扶贫政策与贫困家庭福利——基于贵州贫困地区农村家户调查的分层线性回归分析

根据社会资本分层、数据嵌套的特征,采用分层线性模型,利用贵州省贫困地区农村家户的调查数据,分析不同层级的社会资本影响包括扶贫政策在内的中间变量、进而对家庭福利产生的不同效应及其交互作用。研究表明,在物质资本和人力资本都比较贫瘠的农村贫困地区,社会资本在一定程度上发挥了"穷人资本"的功能,其减轻贫困、改善家庭福利的作用不仅显著,而且还存在进一步发挥的空间。     

中国和印度不平衡发展的比较研究

本文考察了中国和印度近年来经济增长不平衡的情况,并分析了不平衡增长对不均等和贫困的影响。通过对家庭调查数据和官方加总数据的分析,本文发现增长存在不平衡——区域间、产业间和家庭层面上,这表明减贫工作进展不平衡,若增长更平衡,减贫效果可能更好;另外,收入不均等程度也在提高。本文探讨了增长不平衡及其应引起重视的原因。具体讨论围绕"有利的"和"不利的"不均等两个概念展开——不均等与不平衡增长对公平性以及长期增长与发展的有利或不利影响。我们认为,需要制定相关政策,保持有利的不均等——继续鼓励创新和投资,同时降低不利的不均等的程度,尤其是通过人力资本和农村基础设施投资,帮助贫困人口参与市场。

Children's Opportunities in Germany – An Application Using Multidimensional Measures

Single parents and unmarried couples are increasingly replacing the traditional nuclear family. This paper investigates if the greater variety in living arrangements contributes to increased resource disparities among children in Germany. Children in single parent families are disadvantaged in at least three dimensions decisive for their later achievements: material standard of living, parental education, and parental childcare time. We compute multidimensional inequality and poverty indices using SOEP data from 1991 to 2012. We distinguish between parental and publicly provided childcare, which is an increasingly important in‐kind benefit in Germany. We find that both multidimensional inequality and poverty declined as expanded public childcare strongly reduces resource disparities among children.     

Accumulation and distribution of human capital: the interaction between individual and aggregate variables

The paper analyses the joint evolution of accumulation and distribution of human capital in an OLG framework. Dynamics arises from the interplay between human capital distribution and individual variables—inherited human capital and inborn ability. Such interaction drives individual investment in human capital and accumulation in the economy. According to initial distribution the model provides different dynamical behaviours linking growth and inequality; in general economies with a more equal initial distribution grow faster but other cases are possible. Moreover, since the model provides an endogenous threshold for investing in human capital, the distribution is characterised by multi-modality.     

Who benefit from government-led microfinance projects? Evidence from rural China

Drawing from a unique dataset of 2356 Chinese villages, this paper assesses the anti-poverty effect of the largest government-led microfinance project in the developing world. We find that the project can significantly increase the income level in the targeted villages. The main engine of the project lies in the expansion of access to nonfarm activities. We also highlight the importance of institutional circumstance in the effectiveness of the project. Specifically, a more democratized village with less political connection to local governments reaps more benefits from its participation.     

Patterns of poverty among elderly Americans: a latent class Markov model

This article studies poverty persistence and the role of social security programmes on poverty among elderly in the US. We use a Latent Markov model to disentangle unobserved heterogeneity and state dependence. Because of its dynamic nature, unobserved heterogeneity is modelled to vary over time. This allows to capture different latent states of poverty that change over time. Result indicates the existence of three unobserved types evolving over time according to their propensity to be poor. Moreover, a strong persistence in poverty especially for women, individuals living alone and ethnic minorities is found. Finally, the estimates indicate that giving social assistance tends to reduce poverty.     

Poverty effects of food price escalation: The importance of substitution effects in Mexican households

Recent food price increases reportedly caused significant numbers of households to fall into poverty, particularly in the developing world. Most research into the welfare effects of these food price changes assumes constant demand or approximates second order substitution effects. Poverty forecasts with these assumptions may overestimate or underestimate the effect of food price increases in a nation where most households consume diverse food baskets. We account for full substitution by calculating a theoretically consistent food demand system, accounting for household responses to food price changes by decreasing some food purchases and increasing other food purchases. We use Mexican data to confirm the mitigation of adverse welfare effects from food price increases after accounting for country-specific dietary preferences in modeling demand. In comparison to previous literature, our welfare measures predict theoretically consistent numbers of Mexican households entering poverty due to recent food price changes.     

Poverty in US Lesbian and Gay Couple Households

Poverty is a widely researched topic in economics. However, despite growing research on the economic lives of lesbians and gay men in the United States since the mid 1990s, very little is known about poverty in same-sex couple households. This study uses American Community Survey data from 2010 to 2014 to calculate poverty rates for households headed by different-sex versus same-sex couples. Comparing households with similar characteristics, the results show that those headed by same-sex couples are more likely to be in poverty than those headed by different-sex married couples. Despite that overall disadvantage, a decomposition of the poverty risk shows that same-sex couples are protected from poverty by their higher levels of education and labor force participation, and their lower probability of having a child in the home. Lastly, the role of gender – above and beyond sexual orientation – is clear in the greater vulnerability to poverty for lesbian couples.
