Broke,Ill, and Obese: Is There an Effect of Household Debt on Health?

We analyze the association between household indebtedness and different health outcomes using data from the German Socio‐Economic Panel from 1999 to 2009. We control for unobserved heterogeneity by applying fixed‐effects methods and furthermore use a subsample of constantly employed individuals plus lagged debt variables to reduce problems of reverse causality. We apply different measures of household indebtedness, such as the percentage shares of household income spent on consumer credit and home loan repayments (which indicate the severity of household indebtedness) and a binary variable of relative overindebtedness (which indicates a precarious debt situation). We find all debt measures to be strongly correlated with health satisfaction, mental health, and obesity. This relationship vanishes for obesity after controlling for unobserved heterogeneity while it stays significant with respect to worse physical and mental health.     

How responsive is body weight to transitory income changes? Evidence from rural Tanzania

We use time-series of rainfall to estimate the response of body weight to transitory changes in household income in rural Tanzania. We find that the response of body weight to income changes is positive on average, but that the impact is highest for female children, and lower for adults. For female children, a ten-percent increase in household income implies an increase in body weight by about 0.4 kg. In contrast, the body weight of adolescents and young adults is virtually invariant to income changes.     

Why Do the Rich Save More? A Theory and Australian Evidence*

We provide a theory to explain the existence of inequality in an economy where agents have identical preferences and have access to the same production technology. Agents consume a ‘health’ good which determines their subjective discount factor. Depending on initial distribution of capital the economy gets separated into different permanent‐income groups. This leads to a testable hypothesis: ‘The rich save a larger proportion of their permanent‐income’. We test this implication for savings behaviour in Australia. We find that even after controlling for lifecycle and health characteristics, higher permanent income is positively related with higher savings rates and better saving habits.     

Employer pay policies, public transfers and the retirement decisions of men and women in Denmark

The empirical retirement literature measures individual responses to variations in income flows due to public transfers, private individual or employer-provided pensions. We estimate a model accounting for the incentive effects from these sources. A dynamic structural model is extended to allow both individual and employer heterogeneity. This is applied to a Danish matched panel of workers and establishments, spanning a period of reforms to a public early retirement programme. Employer-specific compensation is found to be an important determinant of work and retirement income flows. Employer effects on retirement age are only found among sub-samples where access to public transfers is limited.     

Educational Attainment and Family Background

Abstract. This paper analyses the effect of aspects of family background, such as family income and parental education, on the educational attainment of persons born from 1967 to 1972. Family income is measured at different periods of a child's life to separate long-term versus short-term effects of family income on educational choices. We find that permanent income matters to a certain degree, and that family income when the child is 0–6 years old is an important explanatory variable for educational attainment later in a child's life. We find that short-term credit constraints have only a small effect on educational attainment. Long-term factors, such as permanent family income and parental education, are much more important for educational attainment than are short-term credit constraints. Public interventions to alleviate the effects of family background should thus also be targeted at a child's early years, the shaping period for the cognitive and non-cognitive skills important later in life.     

Rational truth-avoidance and self-esteem

Abstract .  We assume that people have beliefs about their abilities that generate self-esteem, and that self-esteem is valued intrinsically. Individuals face two choices; one of which strictly dominates the other in a pecuniary sense, but necessarily involves gathering information concerning their ability. We lay out the circumstances under which an individual may find it rational to reject the dominant choice, an act that, in psychology is described as avoiding the situation . We then go on to show that the incentive to avoid the truth is increasing in income/wealth and decreasing in self-esteem, the perceived accuracy of one's self-assessment, and the role that luck plays in generating opportunities.     

Wage-distance regulation in social-welfare programs: An option-theory perspective

It is often argued that low-skilled workers have an incentive to escape to the unofficial sector if welfare benefits come too close to the net wage in the official sector. Upper limits of welfare benefits often serve as an instrument to ensure a sufficiently high income differnetial between sectors. However, if unofficial-sector income is insecure, and if a change of sectors is costly, an option value of working in the official sector has to be taken into account. This option value reduces the incentive for lowly skilled workers to give up official-sector jobs. Upper limits of welfare benefits might therefore be defined less restrictively.     

Affirmative action in contest games

This paper analyzes the incentive effects of affirmative action in competitive environments. Competition is between heterogeneous players in a contest game where heterogeneity might be due to past discrimination. Two policy options are analyzed that tackle the underlying asymmetry: either it is ignored and the contestants are treated equally, or affirmative action is implemented to neutralize the disadvantages of discriminated players. Comparing the induced effort exertion under the two policies reveals that in a two-player contest game the normative neutralization objective of affirmative action coincides with higher effort exertion. However, in the multi-player contest affirmative action might have adverse incentive effects as the participation of additional weak players detrimentally affects effort incentives of other players. These results also obtain under imperfect information of the contest organizer.     

Retirement Expectations and Satisfaction with Retirement Provisions

This paper investigates the relationship between subjective expectations regarding the replacement rate of income at retirement and several measures of pension satisfaction. We use panel data on Dutch employees, analyzed with fixed effects models, allowing for correlation between unobserved heterogeneity in satisfaction and optimism or pessimism in expectations. The level of the expected replacement rate is found to be positively related to satisfaction: respondents who revise their expectations of the level of their replacement rate upwards tend to become more satisfied with their pension provisions, in particular with the level of the expected benefits. We do not find robust evidence for a relationship between uncertainty and pension satisfaction.     

Poverty growth in Scandinavian countries: A Sen multi-decomposition

We show in this paper that the growth rate of the Sen index is multi-decomposable, that is, decomposable simultaneously by subgroups and income sources. The multi-decomposition of the poverty growth yields respectively: the growth rate of the poverty incidence (poverty rate) decomposed by subgroups, the growth rate of the poverty depth (poverty gap ratios) decomposed by sources and subgroups, and the growth rate of inequality decomposed by sources and subgroups. We demonstrate that the multi-decomposition is not unique. It is mainly dependent on poverty lines defined on the space of income sources. An application to Scandinavian countries shows that poverty lines based on non-correlation between the income sources imply serious risks of underestimation of the contribution levels of the different components of the global poverty growth. The main contribution of our paper is to pay particular attention to the poverty growth and its source components in order to avoid underestimation of poverty growth.     

Tax treatment of owner occupied housing and wealth inequality

We construct a quantitative general equilibrium lifecycle model with housing tenure decisions to investigate the degree to which wealth inequality in the United States is affected by the preferential tax treatment of home-ownership. Favorable tax treatment of owner occupied housing in the form of home mortgage interest and property tax deductibility, and the untaxed nature of imputed rents, provides a financial incentive for home-ownership over renting as well as an incentive to “over-consume” housing since houses are not fungible. Since the favorable tax treatment of housing disproportionately creates tax savings for the upper quantiles of the income distribution, we quantify how it contributes to the heavily right skewed distribution of wealth in the United States using data from the Survey of Consumer Finances. We consider a revenue-neutral government response to the counter factual experiments of removing the current tax structure on housing. Our quantitative analysis shows that, in terms of distributional effects, removing all of the preferential tax treatments results in an aggregate increase in welfare. However, we do not find any reduction in inequality. We also find that while some re-allocation toward financial assets occurs, households primarily increase their consumption when imputed housing rents are taxed and the property tax deduction is removed. Thus housing tax policy may be effective at encouraging more overall saving through housing assets.     

Deprivation and Subjective Well‐Being: Evidence from Panel Data

This paper uses data from the 2000–08 waves of the German Socio‐Economic Panel dataset (SOEP) to assess the impact of deprivation in various life domains upon individual well‐being. Unobserved heterogeneity is controlled for by means of a random effects model extended to include a Mundlak term and explicit controls for the respondents' personality traits. The paper shows that people care about social comparison information in a number of domains, not just income. Using an equivalent income approach, the estimates suggest that a one standard deviation deterioration of the individual position in the income distribution is as important as a 33.5 percent decrease in own income. This monetary equivalent amounts to an income variation of between 25 and 43 percent when it comes to other deprivation domains, including durables, accommodation, health, and social relations. These results recommend that in the fight against deprivation more emphasis should be directed to these non‐monetary relevant dimensions.     

Motives for household private transfers in Burkina Faso

Resource transfers among households have received considerable interest among economists in recent years. Two of the main reasons for the surge of interest in household transfers are the information on human nature conveyed by transfer behavior and the implication on income redistribution policy that private transfer might have. Empirical studies, however, provide mixed results on transfer behavior. This is because previous inquiries were confronted with several estimation issues and have focused on data from developed countries where private transfers are already small. This paper contributes to the literature on transfer behavior by using a multifaceted econometric approach to examine the motives of household transfers in Burkina, a low-income country with a well-documented tradition of gift exchanges. The findings suggest that risk sharing is not central to transfers. Altruistic transfers are apparent for the middle income class, but not at low income level. The evidence implies that crowding out may be minimal at low income level, suggesting that public transfers targeting poor households may be effective.     

Traffic fatalities: does income inequality create an externality?

Abstract .  Responsible for 20 million severe injuries and/or deaths annually, few epidemics receive less attention than traffic accidents. Going beyond confirming an inverted U-shaped relationship between mean income and fatalities, we show theoretically that income inequality can positively affect fatalities in two ways. Each operates through heterogeneity between road users, and while the direct effect can be expected to evaporate with rising income, the indirect effect may prove to be an externality in that the relationship remains regardless of the level of income. Our model is supported by evidence from 79 countries between 1970 and 2000.     

HETEROGENEITY OR TRUE STATE DEPENDENCE IN POVERTY: THE TALE TOLD BY TWINS

The purpose of this study is to distinguish between two different reasons that poverty could persist on an individual level. This study takes advantage of the similarity within pairs of identical twins to separate family‐specific heterogeneity from true state dependence, where the experience of poverty leads to a higher risk of future poverty. The results, based on a four‐variate probit model, show the importance of true state dependence in poverty. When using a poverty measure based on disposable income, family‐specific heterogeneity explains between 21 and 25 percent of poverty persistence in the Swedish sample of twins.     

Self-rated economic welfare in Russia

Most of those Russian adults who feel that they are poor are not classified as such in the poverty statistics, and most of those who are classified as poor don't feel that way. We study the determinants of peoples’ perceptions of their economic welfare in an unusually rich socioeconomic survey. While income is a highly significant predictor, subjective economic welfare is influenced by many other factors including health, education, employment, assets, relative income in the area of residence and expectations about future welfare. Insights are obtained into how objective data should be weighted in assessing economic welfare.     

Income comparison and happiness: The role of fair income distribution

Relative income gap is one of the most popular approaches for explaining the income–happiness relationship. We argue in this article that when people compare their incomes, they care about distributional fairness more than relative income disparity. It is difficult for us to explain China's income–happiness paradox if we simply compare the income gap and do not explore the income‐generation process leading to income inequality. We therefore employ an approach based on a responsibility‐sensitive theory of justice that decomposes individual income into fair and unfair components. As a proxy for distributional unfairness, unfair income is considered the main source of unhappiness. Using data from the Chinese Household Income Project survey, we find strong support for the negative relationship between income unfairness and happiness. We also find a significantly positive relationship between the relative income gap and income unfairness, which leads us to consider the income comparison hypothesis as the explanation for the income–happiness paradox in a new light. Sensitivity analyses confirm the robustness of our results.     

Local public goods, inter-regional transfers and private information

Suppose that the centre wishes to make transfers between member states of a federation to reduce inequality. However, it lacks precise information concerning the cost differences that are responsible for the initial income inequality. We examine the implications of asymmetric information for the design of the transfer scheme. We show that if member states’ inherent cost levels as local public good providers take discrete values, the first best, or ‘complete information’, transfer scheme may or may not violate incentive compatibility. If inherent cost is a continuous random variable, such a scheme certainly violates incentive compatibility. We also explore the possibility of binding participation constraints. In our model, a binding incentive compatibility constraint leads to a reduction in effort devoted to cost reduction, and a binding participation constraint will also lead to a violation of Samuelson's optimality condition for public good provision.     

Performance-based Wages in Tax Collection: The Brazilian Tax Collection Reform and its Effects

We use panel data from the Brazilian tax collection authority to examine the effects of a major incentive reform instituted in 1989 to improve tax enforcement. Beforehand, fine collections per inspection were relatively stable; however, a striking trend break occurred afterwards, which we attribute to the incentive reform not to changes in the macroeconomy or personal and corporate income tax rates. Our estimates suggest the growth in fines per inspection after the reform is about 75% above what it would have been without it and that there is substantial heterogeneity in the impact of the reform across tax regions.     

Can census data alone signal heterogeneity in the estimation of poverty maps?

Methodologies now commonly used for the construction of poverty maps assume a substantial degree of homogeneity within geographical areas in the relationship between income and its predictors. However, local labor and rental markets and other local environmental differences are likely to generate heterogeneity in such relationships, at least to some extent. The purpose of this paper is to argue that useful if only indirect and suggestive evidence on the extent of area heterogeneity is readily available in virtually any census. Such indirect evidence is provided by non-monetary indicators-such as literacy, asset ownership or access to sanitation-which are routinely included in censuses. These indicators can be used to perform validation exercises to gauge the extent of heterogeneity in their distribution conditional on predictors analogous to those commonly used in poverty mapping. We argue that the same factors which are likely to generate area heterogeneity in poverty mapping are also likely to generate heterogeneity in such kind of validation exercises. We construct a very simple model to illustrate this point formally. Finally, we evaluate empirically the argument using data from Mexico. In our empirical illustrations, the performance of imputation methodologies to construct maps of indicators typically feasible with census data alone is indeed informative about how effectively such methodologies can produce correct inference in poverty mapping.
