Consumption smoothing in Russia

This paper uses panel data from rounds V–IX of the Russian Longitudinal Monitoring Survey (RLMS) to examine the extent to which households are able to protect their consumption from fluctuations in their income. It is found that consumption is only partially protected from idiosyncratic shocks to income with food consumption being better protected than non‐food consumption expenditures. This suggests that adjustments in non‐food expenditures may be an important component of the risk management tools of Russian households. The analysis also provides evidence on the extent and nature of the coping strategies adopted by households. It is demonstrated that households complement their self‐insurance strategies, of borrowing, adjusting their labour supply, and selling assets, with informal risk sharing arrangements with households within their community. An examination of the role of sample selection confirmed that these findings are quite robust to this potential source of bias. Furthermore, accounting for the role of measurement and imputation errors in the measure of household income revealed that OLS estimates may yield a misleading picture about the extent to which urban and rural households are insured from idiosyncratic income shocks.

Social networks near and far: The role of bonding and bridging social capital for assets of the rural poor

With formal insurance and credit markets either absent or inaccessible to rural agents in most poor rural economies, social networks play a highly important role in mitigating the risks that agricultural households face. These kinds of informal insurance schemes are presumed to be most effective in the face of idiosyncratic risk. However, social mechanisms also exist in developing countries that may reduce locally correlated risk such as the adverse economic effects of climatic conditions that affect multiple residents in a village. This paper analyzes the role of localized (bonding) and of spatially dispersed (bridging) social capital in mitigating the impact of idiosyncratic and of locally correlated shocks on farm households’ livestock endowments. Using dynamic panel generalized method of moments (GMM) system estimation with seven‐period panel dataset of over 400 households, we find that bonding social capital is able to protect households’ livestock assets against idiosyncratic shocks, but bridging social capital does not play a role in mitigating the impact of correlated shocks. The results hold up to multiple robustness checks. A test of different hypotheses about the nature of these assets’ trajectories rejects the asset poverty trap hypothesis, and instead finds that livestock asset dynamics are characterized by a single stable equilibrium.     

CAN HOUSEHOLDS AND WELFARE STATES MITIGATE RISING EARNINGS INSTABILITY?

We compare the evolution of earnings instability in Germany and the United Kingdom, two countries which stand for different types of welfare states. Deploying data from the German Socio‐Economic Panel (SOEP) and the British Household Panel Survey (BHPS), we estimate permanent and transitory variances of male income over the period 1984–2009 and 1991–2006, respectively. Studies in this literature generally use individual labor earnings. To uncover the role of welfare state and households in smoothening earnings shocks, we compute different income concepts ranging from gross earnings to net equivalent household income. We find evidence that the overall inequality of earnings in Germany and the United Kingdom has been rising throughout the period due to both higher permanent earnings inequality and higher earnings volatility. However, taking institutions of the welfare state and risk‐sharing households into account, we find that the volatility of net household income has remained fairly stable. Furthermore, redistribution and risk insurance provided by the welfare state is more pronounced in Germany than in the United Kingdom.     

Non-farm Income and Consumption Expenditures in Rural Bangladesh: Empirical Evidence from Multilevel Regression Modelling

This study examines the effects of non-farm income on household consumption expenditures in rural Bangladesh. A two-stage endogenous treatment effect model is built on data from a nationally representative Household Income Expenditure Survey (HIES) 2010 to control selection bias. The HIES follows a hierarchical data structure because the survey is based on two-stage stratified sampling. A multilevel mixed-effects linear regression model is used to capture the unobserved heterogeneity between clusters (PSUs) along with revealing important factors. Results reveal that non-farm income has a significant positive effect on household’s consumption expenditures and non-farm income recipient households spend about 29% more than their counterparts. In addition, higher level of per capita income, education, smaller family size and lower dependency ratio are found to be more effective in increasing consumption expenditures of rural households. Significant cluster-level variations are observed in the analyses. This study recommends that non-farm income generating activities should be encouraged among rural households as this would raise their consumption expenditures and hence, improve welfare and living standards among them.

     

Forests, biomass use and poverty in Malawi

Malawi is one of the poorest countries in Africa and has faced significant deforestation over the years. This paper seeks to examine the nature of the relationship between poverty and forests in Malawi. We try to answer three sets of questions: a) what is the extent of biomass available for meeting the energy needs of the poor in Malawi and how is this distributed? b) To what extent does fuelwood scarcity affect the welfare of the poor? And c) do households spend more time in fuelwood collection in response to scarcity? We answer these questions by matching household surveys with remote-sensing data.Our analyses suggest that biomass scarcity is associated with small but significantly lower household welfare, particularly for the rural poor. At current high levels of scarcity, 80% of rural poor households are likely to benefit from an increase in biomass in the community. Rural women spend more time on fuelwood collection where biomass is scarce. The small decrease in welfare associated with biomass scarcity suggests that households cope with scarcity in a variety of ways. Any effort to reduce degradation and deforestation in Malawi has to build on a clear understanding of household adaptation to fuelwood scarcity.     

Mobile money adoption and households’ vulnerability to shocks: Evidence from Togo

ABSTRACT

We investigate the determinants of mobile money adoption process and whether its use helps households in Togo to be resilient to predictable and unpredictable life events. Using ordered logit and sequential logit models, our results show that in the adoption process, households benefit from weak ties of social groups such as religious group and informal saving group for the adoption of mobile money. We equally find that being client of banks or microfinance institutions act as powerful channels from one step to another in the process. Besides, our findings reveal that households whoever use mobile money seem to be more resilient to climatic shocks such as drought, irregular rain, soil degradation, erosion and fertility reduction and to shock that affect households’ assets (non-climatic: high prices of agricultural inputs). However, the picture is more contrasted when the individuals are classified by disadvantaged groups such as rural people, women, less educated and people with low incomes.     

Shocks, Policy Reforms and Pro-Poor Growth in Bolivia: A Simulation Analysis

This paper analyzes how major external shocks and policy reforms affect Bolivia’s ability to achieve pro‐poor growth. Employing a recursive‐dynamic CGE model, it considers three different scenarios: an optimistic baseline scenario; a more realistic scenario that accounts for two important negative external shocks (declining capital inflows and El Niño); and a scenario that captures the combined effect of the shocks and two major reform projects (development of the gas sector and deregulation of the urban labor market). It turns out that the shocks are likely to impair Bolivia’s medium‐term development prospects, leading to marked increases in both urban and rural poverty. If the reform projects were implemented, the poverty increase caused by the shocks would be more than offset for urban households, but reinforced for rural households.     

"送猪崽"与"折现金":我国产业精准扶贫的路径分析与政策模拟研究

产业扶贫旨在将贫困户的生产活动纳入社会产业大循环,因此其一直是全世界扶贫工作的重要方式和主要目标之一.我国产业精准扶贫出现了两条新路径:一是GTP路径,即向贫困户送猪崽、鸡苗和良种等资本,直接将贫困户的生产纳入当地的产业体系;二是GSP路径,即将扶贫资金折合现金并由贫困户自己决定投资项目和选择产业.文章构建了包括贫困户和非贫困户的微观主体行为模型以及基于农村公平和效率的农村福利模型,分别研究了这两条新路径上贫困户福利和农村福利的动态演变过程,然后使用系统动力学模型进行了政策模拟,拟探索出我国产业精准扶贫的最优路径及其政策支持空间.结果显示:在第3~4年的时间内,GSP路径要优于GTP,但是超过4年,GTP路径上的贫困户福利和农村福利就会累进性超过GSP.而且,在GTP路径上的时间越长,扶贫效果就越好.在中长期,提高贫困户的技术水平,增加贫困户的初始资本额是进一步提高GTP路径上贫困户福利和农村福利水平的重要环节.文章的结论对于提高我国精准扶贫的理论自信,进一步完善我国产业精准扶贫政策体系具有一定的启示.

Risk coping and starvation in rural China

We use a 3-year panel from two poor provinces in Southern China to examine the nature of risks to which rural households are exposed and their ability to insure calorie consumption and spending of total consumption against idiosyncratic shocks to their income. We find that idiosyncratic risks are indeed the main source of income variation in the sample, consumption is better insured than total spending. Unlike total spending where full insurance is rejected in most cases, calorie intake is completely insured for both land-rich and land-poor households in both provinces. Access to even modest amounts of land significantly enhances households’ ability to guard against total spending. Land-rich households are much better insured against total spending than land-poor households. The results are robust across model specifications although Generalized Method of Moments (GMM) estimations increase the magnitude of difference in total spending between the land-rich and the land-poor. Policies targeting poverty reduction and improving land use rights and land access to the poor could potentially improve the overall risk sharing ability of the rural poor.     

Consumption smoothing and vulnerability in Russia

Applying bootstrapped quantile regression to the Russian Longitudinal Monitoring Survey (RLMS) data, we examine the channels through which individuals experience and seek to cope with changes in consumption. We find that married individuals living in small households, with educated heads in urban areas are better equipped to smooth consumption. Investigating the impact of idiosyncratic shocks, we find that the labour market is an important transmission mechanism allowing households to smooth their consumption but also exposing them to risk, mainly through job loss. Outside of pension payments, the formal social safety net does not facilitate consumption smoothing, thus heightening the importance of informal coping institutions. It transpires that both support from relatives/friends and home production act as important insurance mechanisms for the most vulnerable. In contrast with previous findings, it would seem that regardless of its historical, political and social roots, the garden plots and dachas, often romanticized in Russian literature, do provide a means by which ‘urban’ Russians are able to cope with economic fluctuations. We finish by stressing the important policy lessons for Russia's developing market economy.     

Distributional Costs of Housing-price Bubbles: Who pays the Price when Bubbles Deflate?

Abstract

In considering whether asset-price bubbles should be offset through policy, an important issue is who pays the price when the bubble bursts. A bust that reduces the wealth of well-off households only may have small welfare costs, but costs may be sizable if broad swaths of households are affected. This paper uses micro data on millions of households from the US American Community Survey to examine how the bursting of the 1998–2006 housing bubble affected households’ employment, homeownership, home values, and housing costs. To separate dynamics of the housing bust from those of the aggregate downturn, we differentiate between metropolitan areas that did and did not experience bubbles. We find that, for most measures, deteriorations in well-being were more severe in bubble metros than elsewhere, and for several measures, differential effects on less-educated households were also more severe. This underscores the importance of leaning against broad-based housing bubbles via appropriate policies, as burdens of adjustment fall differentially on people not well prepared to bear them.     

Can conditional cash transfer programs serve as safety nets in keeping children at school and from working when exposed to shocks?

Income shocks on poor households are known to induce parents to take their children out of school and send them to work when other risk-coping instruments are insufficient. State dependence in school attendance further implies that these responses to short-run shocks have long-term consequences on children's human capital development. Conditional cash transfer (CCT) programs, where the condition is on school attendance, have been shown to be effective in increasing educational achievements and reducing child work. We ask the question here of whether or not children who benefit from conditional transfers are protected from the impacts of shocks on school enrollment and work. We develop a model of a household's decision regarding child school and work under conditions of a school re-entry cost, conditional transfers, and exposure to shocks. We take model predictions to the data using a panel from Mexico's Progresa experience with randomized treatment. Results show that there is strong state dependence in school enrollment. We find that the conditional transfers helped protect enrollment, but did not refrain parents from increasing child work in response to shocks. These results reveal that CCT programs can provide an additional benefit to recipients in acting as safety nets for the schooling of the poor.

Measurement of Changes in Economic Welfare in India: 1970–2001

This paper provides time series estimates of measures of economic welfare, inequality, decile class specific true cost of living index and poverty measures based on 20 rounds of National Sample Survey data for the period 1970–2001. It has estimated piece-wise Linear Expenditure System (LES) for very poor, moderately poor, non-poor low and non-poor high expenditure groups for rural as well as urban areas. Money metric utility for deciles are derived from the money metric utility function and social welfare index is constructed by aggregating metric utility of the deciles. Using social welfare index as well as real per capita consumption, the paper analyses the changes in economic welfare over the three decades. Using conventional measures, the paper analyses the changes in poverty and inequality during 1970–2001. The paper also provides estimates of the welfare effects of commodity prices.

     

Report of China Household Income Disparity

Based on China Household Finance Survey (CHFS) data, China’s Gini Coefficient stood at 0.61 in 2010, above the global average of 0.44, according to the World Bank. The high Gini Coefficient represents a large income disparity of the country. It is understandable that a high Gini is common in fast-growing economies and can be reduced through government’s transfer payments given the experience of OECD countries. This paper illustrates the breakdown of China’s Gini, regional, rural and urban differences in household income. Specifically, it is found that poor health, insufficient social welfare and low education level are the main reasons for poverty of rural households. This paper also provides solutions to reduce the Gini coefficient. In the short term, China government can invest more on social insurance and implement large-scale transfer payments. The figure shows that China government has sufficient financial sources to strengthen secondary distribution to subsidize the low-income group. In the long term, government can increase overall educational level and reduce the opportunity inequality to narrow the income gap.     

信誉、财富与农村信贷配给——欠发达地区不同农村金融机构的供给行为研究

文章使用2006年云南、宁夏近800个农户家庭的调查数据,实证分析了欠发达地区不同农村金融机构的信贷供给行为.在区分农户的名义需求和有效需求的基础上,研究发现信用社和银行在发放贷款时偏向富有农户,民间借贷者没有这种偏向,因而其服务的覆盖面远远超过正式机构.两者都重视农户的信誉状况,但信用记录没有实现共享.这些行为的差异主要来源于各类金融机构之间信息成本和交易成本的差别.     

Incomplete Markets, Transitory Shocks, and Welfare

Although equilibrium allocations in models with incomplete markets are generally not Pareto-efficient, it is often argued that quantitative welfare losses from missing assets are small when time horizons are long and shocks are transitory. In this paper we use a computational analysis to show that even in the simplest infinite horizon model without aggregate uncertainty welfare losses can be substantial. Furthermore we show that in this model welfare losses from incomplete markets do not necessarily disappear when one considers calibrations of the model in which agents become very patient. We argue that when the economic model is calibrated to higher frequency data, the period persistence of negative income shocks must increase as well. In this case the welfare loss of incomplete markets remains constant even as agents' rate of time preference tends to one. Journal of Economic Literature Classification Numbers: D52, D58, D60.     

Welfare Policy and Precarious Lives: “Welfare Reform” Revisited

Abstract:

Although welfare reform has not been one of the most highly visible policy agendas for the Trump administration, restricting access to public assistance programs has been a part of proposals and actions in a number of areas. The Trump administration’s overall approach to welfare reform was articulated formally in 2018 in an Executive Order and a Council of Economic Advisers Report. To provide some context for a discussion of these two documents, the article begins with a discussion of the different meanings of “welfare reform” identified in institutionalist literature, and a brief overview of some important findings on the impacts of the 1996 welfare reform. It then highlights some key aspects of the Trump administration’s approach to welfare reform and responses from the poverty research and advocacy community.     

Price hike of staple food,nutritional impact and consumption adjustment: evidence from the 2005–2010 rice price increase in rural Bangladesh

This paper studies the nutritional impact of the rice price increase between 2005 and 2010 on households in rural Bangladesh and their resulting adjustment in consumption of rice, non-rice food and non-food items. We compare net rice buyers, who suffer from a negative income effect, with self-sufficient households that do not suffer from any such effect. Our findings indicate that rural households in Bangladesh cope well with the surge in the domestic rice price as indicated by the absence of any effect on their calorie intake and dietary diversity. In fact, both types of households similarly change their consumption of rice, non-rice grain, pulses, protein, fruits and other items. Furthermore, we do not find any evidence of buyers’ switching towards low-quality items in a food group. In a separate analysis, we compare net rice sellers with self-sufficient households and arrive at a similar conclusion. In both cases, income plays a crucial role in the consumption of non-rice food and non-food items, indicating the importance of effective income support programs at the time of price shocks in staple food items.
