Nepal's civil war and the changing sources of income: The role of sectoral shifts and remittances in mitigation and recovery

Given the increased worldwide unrest and a large number of displaced individuals, understanding the economic impacts of civil war has been the subject of growing attention by academics and policymakers. The 10‐year civil war in Nepal from 1996 to 2006 provides an opportunity to assess the impact of civil unrest on income sources and remittance patterns. In this study, we examine the changes in household income generating processes over the period of the Nepali civilwar. Using survey data from the Nepal Living Standards Survey (NLSS) in 1995/1996 and 2010/2011, we observe household income and remittance patterns before and after the civil war. Specifically, we employ a difference‐in‐difference estimator that focuses on the heterogeneity in civil unrest within Nepal to examine how the civil war impacted the sources of household income. Within the context of a slower growth rate of income after the revolution for those in the hardest hit districts, we find that there was also a change in the composition of income sources. In particular, our results suggest that there was a shift from a reliance on wages in the nonagricultural sector to wages in the agricultural sector; that there was a shift from external remittances to internal remittances; and finally that home production—the market value of items produced and consumed within the household—may be taking the place of income in regions hit by unrest. “People living in zones of war are maimed, killed, and see their property destroyed. They may be displaced or prevented from attending school or earning a living. To the extent that these costs are borne unequally across groups, the conflict could intensify economic inequality as well as poverty. The destruction (and deferred accumulation) of both human and physical capital also hinder macroeconomic performance, combining with any effects of war on institutions and technology to impact national income growth. Understanding the economic legacies of conflict is important to the design of post‐conflict recovery” (Blattman & Miguel, 2010).     

Education, inequality and transition

I consider evidence on differences in access to education and in learning achievement within the countries of Central and Eastern Europe and the former Soviet Union. The situation inherited from the communist period is first summarized: there were some significant disparities with, for example, family background having a strong association with tertiary enrolments, as in Western countries. Analysis of the transition period focuses on differences in access and achievement associated with household income and geographic location. Disparities are not the same across the region; in some countries, such as Russia, there are clear grounds for serious concern, but it is unlikely that any country has cause for complacency.     

中国城镇、农村居民消费的分析与比较

在借鉴西方跨期最优消费选择理论和相对收入假说所提出的"棘轮效应"的基础上,估计中国的消费函数,鉴于我国城镇和农村居民在消费行为方面存在差异,本文分城镇居民和农村居民对模型单独进行检验,考察两者在影响消费的因素方面的差异,并试图找到产生这种差异的原因。最后,根据城镇居民和农村居民消费函数的不同特点,提出拉动居民消费的政策建议。     

Skill Composition,Fertility, and Economic Growth

While high fertility persists in the poorest countries and fertility declines with per capita income in developing countries, fertility and per capita income are now positively associated across most developed countries. This paper presents a model where a U‐shaped relationship between overall fertility and per capita income reflects within country differences in workforce skill composition and household choice of occupation, fertility, and childrearing. The fraction of skilled workers rises with economic growth. By allowing for both differences in the fertility of skilled and unskilled workers and purchased childrearing inputs, we explain a poverty trap with high fertility, fertility decline with economic development, and the possible reversal of fertility decline in a developed economy where most workers are skilled.     

DIFFERENCES IN NEEDS AND ASSESSMENT OF INCOME DISTRIBUTIONS*

The literatures on the assessment of income distributions and on differences in needs are not well integrated. The theoretical literature providing results about evaluations and comparisons of income distributions does not, in the main, consider the implications of non-income differences between income-receiving units, while the equivalence scale literature providing results about the relationship between living standards, incomes and household composition does not consider distributional implications. The aim of this survey is to go some way towards integrating these separate literatures; to consider how to evaluate and compare income distributions while at the same time taking explicit account of differences in household composition.     

GENERATING INTERNATIONALLY COMPARABLE INCOME DISTRIBUTION DATA: EVIDENCE FROM THE FEDERAL REPUBLIC OF GERMANY (1974), MEXICO (1968) AND THE UNITED KINGDOM (1979).

In this article an attempt is made to generate internationally comparable income distribution data for the Federal Republic of Germany (1974), Mexico (1968) and the United Kingdom (1979). To that end, the same income concept and income unit were adopted for each country, i.e. respectively household available income and the household. Moreover, incomes from various sources were adjusted for inconsistency with National Accounts according to Altimir's methodology. The paper finds that the distribution of persons by household income per equivalent unit is probably the best way of looking at the distribution of economic welfare. It further demonstrates that the distribution of persons by household available income per capita is much closer to this 'ideal' distribution than the distribution of households by household available income. Finally, the paper discusses some of the problems arising from the fact that one normally works with grouped data. It is found that in the case of the three countries under study, grouping is likely to have had only a small impact on the results.     

How Much Income Mobility is There in Britain?

Using the first four waves of the British Household Panel Survey (1991–4) and a variety of methods, we show that there is much mobility in household net income from one year to the next in Britain. However most income changes from one year to the next are not very large, and when incomes are longitudinally averaged so that transitory variations are smoothed out, substantial 'permanent' income differences are revealed. There is some evidence of greater mobility for those in the tails of the income distribution relative to the middle, and for elderly persons compared to non-elderly persons     

Cross-border commuting and consuming: an empirical investigation

This article contributes to our understanding of cross-border activity in general and the determinants of cross-border trade in particular by focusing on the part of cross-border sales that arise due to work-related cross-border crossings of households. We analyse empirically how cross-border consumption expenditures vary across product and services categories as well as household characteristics using representative household survey data of cross-border commuters to Luxembourg. In total, these households spend an estimated 17% of their gross annual income across the border, contributing about 10% to the total household final consumption expenditure (HFCE) in Luxembourg. Cross-border expenditure is linked to individual- and household-related characteristics and to distance between home and work. Cross-border commuters systematically exploit arbitrage opportunities that arise because of existing price level (index) differences between the country of work and the country of residence.     

Calculation and decomposition of income inequality in low- and middle-income countries: a survey data analysis

This article estimates income inequality in a sample of four low- and middle-income (LMI) countries namely; Albania, Nepal, Tajikistan and Tanzania using the household survey data – Nepal Living Standard Measurement Survey Second. First, we estimate the income generation function for each country and calculate the income inequality using Gini index (GI). Second, we decompose the income Gini into the determinants of income generation functions. Based on the decomposition result, socio-economic factors are the most important determinants of income inequality followed by geographic factors. Demographic factors have the least effect on income inequality in all four countries. Third, we propose a new method to quantify the effect of change in each covariate of income generation function on income Gini. That allows us to quantify the effects of change in specific policy such as increase in investment in schooling or public health to specific group of the population in society on income inequality. A carefully chosen, integrated policy can significantly reduce inequality in all four countries under study.     

Saving and the intra-household distribution of income: an empirical investigation

This paper presents an empirical analysis of the relationship between household saving and the distribution of income within the household. Various theoretical reasons why the level of saving might depend on the latter are given. Some of these can be rationalized within the usual “unitary” model of household decision but others recognize explicitly that different members of the household may have different preferences about how much to save.Particular attention is paid to saving for retirement since the facts that wives are, on average, younger than their husbands and women have longer life expectancies means that wives typically anticipate a longer retirement period than their husbands. Thus wives may prefer to save more for retirement than their husbands.The empirical analysis uses a sample of Canadian households from five Family Expenditure Surveys. These surveys include measures of financial saving as well saving in retirement accounts. After accounting for many of the other influences on saving (for example: age, household composition, occupation and education levels but not household income) we find some effects of the intra-household distribution of income on savings rates. The parameter estimates suggest that the household saving rate decreases with the share of the wife in household income.     

THE URBAN–RURAL INCOME GAP AND INEQUALITY IN CHINA

Using new household survey data for 1995 and 2002, we investigate the size of China's urban–rural income gap, the gap's contribution to overall inequality in China, and the factors underlying the gap. Our analysis improves on past estimates by using a fuller measure of income, adjusting for spatial price differences and including migrants. Our methods include inequality decomposition by population subgroup and the Oaxaca–Blinder decomposition. Several key findings emerge. First, the adjustments substantially reduce China's urban–rural income gap and its contribution to inequality. Nevertheless, the gap remains large and has increased somewhat over time. Second, after controlling for household characteristics, location of residence remains the most important factor underlying the urban–rural income gap. The only household characteristic that contributes substantially to the gap is education. Differences in the endowments of, and returns to, other household characteristics such as family size and composition, landholdings, and Communist Party membership are relatively unimportant.     

收入不平等与家庭借贷行为*——家庭为追求社会地位而借贷的动机真的存在吗

本文利用中国家庭金融调查(CHFS)2011年度的调查数据,考察了收入不平等对家庭借贷行为的影响,并验证了家庭是否存在为追求社会地位而借贷的动机。研究表明：（1）收入不平等并不是影响家庭是否借贷的主要因素,但是对家庭的负债规模存在十分显著的抑制作用;（2）收入不平等的扩大并不会促使中低收入家庭寻求借贷或提升家庭负债规模,我国家庭并不存在为了追求更高的社会地位而进行借贷的动机;（3）收入不平等的扩大有利于高收入家庭获得更多的正规金融借贷,中低收入家庭则会较多地依赖于非正规金融借贷;（4）户主的人口统计学特征、家庭经济特征以及家庭所处地区特征均是影响家庭借贷行为的重要因素,在正规金融和非正规金融市场上,影响家庭借贷行为的因素存在较明显的差异。     

Does medicaid generosity affect household income?

Almost all recent literature on Medicaid and labor supply has used Affordable Care Act (ACA)-induced Medicaid eligibility expansions in various states as natural experiments. Estimated effects on employment and earnings differ widely due to differences in the scope of eligibility expansion across states and are potentially subject to biases due to policy endogeneity. Using a Regression Kink Design (RKD) framework, this paper takes a new approach to the identification of the effect of Medicaid generosity on household income. Both state-level data and March CPS data from 1980 to 2013 suggest that generous federal funding of state-level Medicaid costs have a negative effect on household income. The negative impact of Medicaid generosity on household income is more pronounced at the lower end of the household income distribution and on the income and earnings of female heads.     

THE STANDARD OF LIVING IN THE UNITED STATES

A common approach to the evaluation of the standard of living is based on a function of real income. In the United States this often takes the form of CPI-deflated mean household income. Material well-being is more appropriately evaluated using a consumption-based index. Using data from the Consumer Expenditure Surveys we find that real mean income provides an inaccurate representation of the level and trend of the standard of living relative to real per equivalent total expenditure in the postwar United States. The differences between real income and real total expenditure per household equivalent member are found at all levels of aggregation.     

EFFECTS OF PERSONAL INCOME TAX ON INCOME DISTRIBUTION: EXAMPLE FROM BULGARIA

This study utilizes the 1992 Bulgarian household budget survey to analyze the distribution of income and income tax burden. Results indicate that the country is characterized by low income inequality, though this is changing rapidly. The findings also show that the present income tax system is progressive and that the urban sector pays much more relative to its income. Despite a steeply graduated statutory tax rate schedule, effective progression is rather modest, indicating significant tax evasion. However, one must view the results of progressivity and urban bias cautiously. As in-kind income becomes monetized and as the economy becomes more market-oriented, both progressivity and urban/rural differences will wane over time.     

Household Debt,Consumption, and Income Inequality

Using the Johansen and Engle–Granger cointegration tests, we show that there is one cointegrating relationship between household debt, consumption, and income inequality in the United States for the period from 1929 to 2009. Given this result, we use a Vector Error-Correction model to further understand the dynamics among the three variables. Results indicate that increases in income inequality and consumption directly contribute to increases in household debt. Interestingly, the results reveal some feedback from household debt to income inequality. We also show that debt-driven consumption should be viewed with caution as the results show that increases in household debt correspond with future declines in the rate of consumption.     

The response of household debt to income inequality shocks: a heterogeneous approach

This article explores the impact of changes in income inequality on household indebtedness using Pedroni's heterogeneous panel VAR. As a result, we find evidence in support of large cross-country heterogeneity in the responses of household leverage to income inequality shocks. We also find that such heterogeneity stems from differences in the strength of financial regulations and supervision.     

自然灾害发生前后灾区农户收入影响因素的对比分析——以汶川为例

本文以汶川地震为研究背景,通过构建灾害发生前后灾区农户的收入模型,实证研究了灾前、灾后影响受灾地区农户收入的主要因素及其异同。除此之外,本文从高低收入组间差异角度,实证分析了灾害发生前后农户收入影响因素的组间差异。研究表明,无论是灾前还是灾后,外出务工对农户收入都具有显著的正向增长作用,且灾后这种影响比灾前有所扩大。地震发生后,家庭经营收入对农户收入的增长作用比灾前有所增加。地震对高低收入组农户外出务工情况产生了不同程度的负面影响,由此可能导致高低收入组间农户收入差距的进一步扩大。最后,本文提出了相应的政策建议。     

USING PSEUDO‐PANELS TO MEASURE INCOME MOBILITY IN LATIN AMERICA

This paper presents a comparative overview of mobility patterns in 14 Latin American countries between 1992 and 2003. Using three alternative econometric techniques on constructed pseudo‐panels, the paper provides a set of estimators for the traditional notion of income mobility as well as for mobility around extreme and moderate poverty lines. The estimates suggest very high levels of time‐dependent unconditional immobility for the Region. However, the introduction of socioeconomic and personal factors reduces the estimate of income immobility by around 30 percent. There are also large variations in country‐specific income mobility (estimated to explain some additional 10 percent of inter‐temporal income variation). Analyzing the determinants of changes in poverty incidence within cohorts revealed statistically significant roles for age, gender, and education of the household head, the latter subject to distinctive effects across levels of attainment and transition in and out of poverty.     

Headship rates and the household formation process in Great Britain

This paper looks at the changes in headship rates in Great Britain over the period 1960–1979, and attempts to explain them in terms of economic variables, such as real income and the real cost of housing. Such variables are found to be significant for some household types, but not for others. Notably, young single person household formation appears to be more supply constrained and to respond to appropriate supply variables.

Finally, some comparisons are made with similar studies done on similar data from the USA and France. These studies reeal a number of features in common, but also some differences, and these are commented upon.
