医疗保险与消费:来自新型农村合作医疗的证据

本文利用农村引入新型农村合作医疗这一政策变化来研究医疗保险的获得对农村居民消费的影响。结果表明,新农合使得非医疗支出类的家庭消费增加了约5.6个百分点。这一正向作用随医疗保险保障水平的提高而增强,而且在没有医疗支出的家庭中仍然存在。同时,新农合对消费的正向影响在收入较低或健康状况较差的家庭中更强。这些结果都与医疗保险减少了预防性储蓄的假说相一致。另外本文发现,新农合的效果随农户在这个项目中的经历而变化。实际上只有在那些有村民获得保险补偿的村子,保险对消费的正向影响才显著,而且在这些村子中,新农合对新加入农户的消费的影响明显小于对参合一年以上农户的消费的影响。     

Local elections and consumption insurance

During our sample period from 1987 to 2002, Chinese villages completed the transition from government‐appointed village leaders to elected ones. This article examines if and how much democratic elections of the village leaders affected consumption insurance by Chinese village residents. Exploring a panel dataset of 1,400 households from this period, we find that consumption insurance is around 20 percent more complete with elected village leaders. Furthermore, local elections improve consumption insurance only for the poor and middle‐income farmers, but not for the rich. The results are robust when we allow for pretrending, potential endogeneity of elections, and higher measurement errors for rich residents. We also find that the effects on consumption insurance are stronger when closer to the upcoming election year and when the village committees consist largely of non‐Communist Party members. These findings suggest that the election effects on consumption insurance partly come from increasing accountability to local constituents.     

Revealed community equivalence scales

This paper estimates the equivalence scale revealed by discretionary community allocations of welfare benefits to poor households. I apply the proposed approach to a subsidized rice program in Indonesia in which villages designated program beneficiaries, and estimate the equivalence scale implicit in the beneficiaries they selected. I find that the “revealed community equivalence scale” for this program lies much closer to per capita expenditure than traditional demand-based equivalence scales, particularly in the poorest communities. This suggests that per capita expenditure may be closer to how poor communities actually compare households when allocating aid than previously thought.     

Informal Insurance Arrangements with Limited Commitment: Theory and Evidence from Village Economies

Recent work on consumption allocations in village economies finds that idiosyncratic variation in consumption is systematically related to idiosyncratic variation in income, thus rejecting the hypothesis of full risk-pooling. We attempt to explain these observations by adding limited commitment as an impediment to risk-pooling. We provide a general dynamic model and completely characterise efficient informal insurance arrangements constrained by limited commitment, and test the model using data from three Indian villages. We find that the model can fully explain the dynamic response of consumption to income, but that it fails to explain the distribution of consumption across households.     

Does grassroots democracy reduce income inequality in China?

Using village and household survey data collected from 48 villages of eight Chinese provinces for the period 1986–2002, this paper studies how the introduction of village elections affects income distribution at the village level. We estimate both a static fixed-effect panel model and a dynamic panel model for the within-village Gini coefficient and take care of the endogeneity of the introduction of elections. The dynamic panel model shows that having elections reduces the Gini coefficient by 0.04, or 14.3% of the sample average. We also find that elections tend to increase the income shares of poorer portions of the population. Further econometric analysis based on dynamic panel models shows that elections increase per-capita public expenditures by 271 Yuan, but do not increase the level or progressiveness of net or total income transfer in a village. Therefore, elections' positive role in reducing income inequality is not played through more income redistribution, but through more pro-poor public investment.     

The impacts of social pension on rural household expenditure: evidence from China

In 2009, China began to implement a new social pension scheme in rural areas. We examine the impacts of this social pension on two main components of rural household expenditure, consumption and agricultural production investment. Our findings show that on average, rural households increase consumption by 1–3% and agricultural investment by as high as 6–9% in pilot counties. Further estimations reveal that the pension mainly affects the households with old-aged members and the poorer families, and that the saving rate hasn’t been changed by the pension, which support more the contingent income than the life-cycle hypothesis. We also find that among various types of expenditures, the most dramatic increases have occurred in food consumption and operational inputs on agricultural production.     

EFFECTS OF TAXES AND BENEFITS ON INCOME DISTRIBUTION IN KOREA

This paper examines the redistributive effects of Korea's fiscal policies, including consumption taxes and in‐kind benefits. Using the Household Income and Expenditure Survey of 2007, we find that taxes and transfers reduce income inequality in Korea by 13.8 percent. Contrary to the popular belief that direct taxes are the key tool for redistribution, in‐kind benefits, direct taxes, and social security contributions all decrease the Gini coefficient by 6.7, 4.7, and 2.9 percentage points, respectively. The redistributive effect of consumption taxes is small and negative (?0.5 percentage point). Policy simulations indicate that education spending financed by the personal income tax has a positive redistributive effect and that the lower 70 percent of households enjoy positive net benefits. Spending targeting the poor has a strong redistributive effect, which implies low popularity because the majority of households face net losses.     

Do the Rich Save More in Japan? Evidence Based on two Micro Data Sets for the 2000s

Using two household surveys, this paper investigates whether the saving rates of richer households are higher than those of poorer households in Japan. We construct a number of proxies for lifetime wealth, including those original to this study, and find marginally positive correlations between saving rates and lifetime wealth for working age households. We further find that the relationship between saving rates and lifetime wealth differs depending on the life stage of individual households. Older households with higher lifetime wealth appear to be dissaving to some extent, which is more or less consistent with the lifecycle model of consumption.     

健康风险冲击对农户收入的影响

本文基于中国8个省份、1354个农户、跨度15年的微观面板数据,测算了大病冲击对于农户长期收入的影响以及健康风险冲击持续的时间。我们发现:(1)大病冲击在随后的12年里对于农户人均纯收入都有显著的负面影响;(2)大病冲击对于农户的短期与中期影响使得患病户人均纯收入平均降低5%—6%;(3)健康风险冲击的长期影响可持续大约15年,并且冲击对于中低收入农户的影响更为严重。     

Risk Sharing and Information in Village Economies

Arrangements for achieving efficient risk-sharing vary depending on the information available to agents in the economy. The usual Euler equation restricts efficient allocations in an economy which obeys the permanent income hypothesis, while efficient allocations in an economy with private information and long-term contracts satisfy a symmetric restriction, but not the Euler equation. Full insurance arrangements are unique in that they satisfy both restrictions.
We look at an environment in which it seems likely that long-term contracts play a role in mitigating the effects of private information: three village economies in South India. The evidence that consumption allocations satisfy the private information restriction is quite strong for households in two of the three villages; the evidence for the third village suggests that while consumption for some households satisfies the private information restrictions, other households' consumption obey the permanent income hypothesis.     

The myth of post-reform income stagnation: Evidence from Brazil and Mexico

Economic policies are often judged by a handful of statistics, some of which may be biased during periods of change. We estimate the income growth implied by the evolution of food demand and durable good ownership in post-reform Brazil and Mexico, and find that changes in consumption patterns are inconsistent with official estimates of near stagnant incomes. That is attributed to biases in the price deflator. The estimated unmeasured income gains are higher for poorer households, implying marked reductions in “real” inequality. These findings challenge the conventional wisdom that post-reform income growth was low and did not benefit the poor.     

TAXES,INCOME, AND RETIREMENT SAVINGS: DIFFERENCES BY PERMANENT AND TRANSITORY INCOME

This article examines the determinants of and benefits from saving for retirement in tax‐preferred accounts by permanent and transitory income levels. We find that higher incomes (both permanent and transitory) are associated with a greater probability to contribute and larger contributions. We also find that tax benefits for retirement savings increase strongly with income, although the increase is slightly smaller when taxpayers are ranked by their permanent (rather than current) income. In addition, we find that a large portion of the benefits from the Saver's Credit go to taxpayers who would not be eligible based on their permanent income. Finally, we find that recent tax changes (including the introduction of the Saver's Credit) significantly increased contributions among low‐income households, although the effect was centered among those with only transitorily low income.

The benefits and costs of the section 8 existing housing program

The demand-side Section 8 Existing Housing Program begun in 1975 is currently the second largest low-income housing program in the United States with over one million units. This paper presents estimates of the benefits and costs of the program and examines its allocative and distributive effects. The effects of Section 8 Existing are compared with those under an alternative program of equal-subsidy, unrestricted cash grants. Among other things, it is found that the average monthly subsidy of $100 is valued by recipients at $83 on average. Recipients are induced to consume 11 percent more housing and 6 percent less of other goods than they would with the cash grant. Recipient households near the eligibility income limits do not receive so large a benefit as to become better off than ineligible households. The poorest and largest families receive the largest benefit, other things equal. However, most poorer families are excluded while some richer families participate and equally situated families do not receive the same offer of assistance.     

The effect of rural labor migration on poverty alleviation: a village-level study in China

The construction of the new socialist countryside is being carried out in China nowadays. Although lots of successful experience has been gotten, different problems occur in various regions yet. To analyze the relationships among rural labor migration, poverty alleviation and characteristics of migrants is important in considering the effect of rural labor migration on the construction of the new socialist countryside. Available sampling and typical case study are adopted and 236 questionnaires are collected from[bur villages in northwest GuangxL China, Daxin Lixin, Longhe and Yongchang. We analyze the rural labor migration status, characteristics of migrants, remittance situation and income, household income and the ratio of remittance income to total household income. A bout 2/3 of the households have migrants in surveyed villages. And nearly half of the migration households have only one fam- ily member as migrants in the four villages. The migrants mainly comprise male and the younger, with the education level of junior middte school and higher More than half of the migrants are employed in Guangdong Province. But the characteristics of migrants in Yongchang are more diverse. The rural labor migration in the village is extremely active and extensive. And over 60% of the household with family members as migrants have remittance income. The rate in Yongchang is extremely high (80%). And the income of households with migrants getting remittance income significantly higher than their counterparts. More than half of their income comes from remittance as far as the former kind of household is concerned And in Yongchang, the rate is nearly 80%. The conclusion is that rural labor migration is popular and extensive in lots of villages. And the migration and remittance play an important role in rural household income, especially in some poor villages. For this kind of village, the rural labor migration may be some "compulsory course" in rural development. And the rural labor emigration is an essential way in poverty al-leviation. This is the first step in the construction of the new socialist countryside.     

DETERMINANTS OF SCHOOL ENROLLMENT AND PERFORMANCE IN BULGARIA: THE ROLE OF INCOME AMONG THE POOR AND RICH

Where credit markers are incomplete, households must finance educational investments out of past savings or current earnings. Poor households, with low savings and low current income, may accordingly be highly constrained in their educational choices, whereas richer households are not. The commonly used log-expenditures specification of the relationship of income to school enrollment may therefore be imprecise. Using data from the 1995 Bulgarian Integrated Household Survey, this analysis shows that the roughly 50% of Bulgarian households with expenditures per adult-equivalent of less than 5,000 Leva (1995 prices) are financially constrained in their educational choices, while richer households are not.     

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.     

The economic importance of non-timber forest products (NTFPs) for livelihood maintenance of rural west African communities: A case study from northern Benin

Non-timber forest products (NTFPs) contribute significantly to a rural household's livelihood in the African semi-arid tropics. This study examines the income from NTFPs and the dependency on these of different socio-economic groups in Northern Benin. Using survey data from 230 households of two villages, we firstly compared incomes of five different ethnic groups being differentiated by their traditional source of livelihood and regional provenance. Secondly, we investigated disparities between three income groups. On average, income from NTFPs accounted for 39% of total household income and had a strong equalizing effect on it. However, the economic relevance of NTFPs differs between households: Poorer households are relatively more dependent on NTFPs in order to fulfill basic needs than wealthier households. However, the latter extract more NTFPs in quantitative terms and have significantly higher cash returns than poorer ones. This is mainly due to a significant greater land holding. Moreover, our study revealed that net income from NTFPs reflects traditional sources of livelihoods of different ethnic groups. In conclusion, both conservation and development strategies should take into consideration the socio-economic context of different beneficiaries of savanna woodland resources in order to apply appropriate measures to poverty reduction.     

The incidence of Medicare

The Medicare program transfers nearly $300 billion annually from taxpayers to beneficiaries. This paper considers the incidence of such transfers in the context of a life cycle model with uncertainty about future health care expenditures. We find the distributional consequences of the Medicare program are roughly neutral in dollar terms; households living in high income neighborhoods pay more in taxes, but they also receive more in benefits. These dollar flows, however, ignore the insurance value of the Medicare system. Given the incomplete insurance coverage of lower income elderly households prior to the Medicare program, the money-metric benefits to lower income groups exceed the dollar flows, suggesting that Medicare redistributes more than a simple accounting exercise would suggest.     

Poverty Dynamics,Violent Conflict,and Convergence in Rwanda

This paper analyzes the poverty impact of the violent events that affected Rwanda in the 1990s. The main objective of the paper is to identify systematically potential mechanisms linking violent conflict with changes in poverty across provinces and households in Rwanda before and after a decade of violence. In accordance with emerging literature on the long‐term economic effects of violent conflict, we find empirical evidence for economic convergence between richer and poorer Rwandan provinces and households following the conflict shocks. Using a small but unique panel of households surveyed before and after the conflict period, we find that households whose house was destroyed or who lost land ran a higher risk of falling into poverty. We do not find much evidence for an economic effect of violent deaths at the household level due to substitution effects of labor within the household. Non‐violent deaths however seem to increase income per adult equivalent for the survivors. Results are shown to be robust to sample selection and IV models.
