Child labor and agricultural shocks

This paper examines the relationship between household income shocks and child labor. In particular, we investigate the extent to which transitory income shocks lead to increases in child labor and whether household asset holdings mitigate the effects of these shocks. Using data from a household panel survey in Tanzania, we find that both relationships are significant. We investigate mechanisms that could account for these results, including buffer stocks and borrowing.     

Reliability of recall in agricultural data

Despite the importance of agriculture to economic development, and a vast accompanying literature on the subject, little research has been done on data quality. Due to survey logistics, agricultural data are usually collected by asking respondents to recall the details of events occurring during past agricultural seasons, potentially leading to recall bias. The problem is further complicated when interviews are conducted over the course of several months, thus leading to recall of variable length. To test for recall bias, the length of time between harvest and interview is examined for three African countries with respect to several common agricultural input and harvest measures. The analysis shows little evidence of large recall bias impacting data quality. There is some indication that more salient events are less subject to recall decay. Overall, the results allay some concerns about the quality of some types of agricultural data collected through recall over lengthy periods.     

Employment Protections for Older Workers: Do Disability Discrimination Laws Matter?

Although age discrimination laws boost employment of older workers, some are exempt from age-law protection and may be better protected by disability discrimination laws. Disability laws may raise the costs of employing the disabled, however, generating mixed predictions regarding employment effects of protection by both types of laws. This study finds that employment of older disabled workers with the coupled laws is lower than those with age-law protection only; employment of the younger disabled is higher with the coupled laws. For older disabled workers, earnings of those with the coupled laws are lower than their counterparts with only age-law protection. (JEL J78 , K31 , J00 )     

Explaining variation in child labor statistics

Child labor statistics are critical for assessing the extent and nature of child labor activities in developing countries. In practice, widespread variation exists in how child labor is measured. Questionnaire modules vary across countries and within countries over time along several dimensions, including respondent type and the structure of the questionnaire. Little is known about the effect of these differences on child labor statistics. This paper presents the results from a randomized survey experiment in Tanzania focusing on two survey design choices: different questionnaire design to classify children work and proxy response versus self-reporting. Use of a short module compared with a more detailed questionnaire has a statistically significant effect, especially on child labor force participation rates, and, to a lesser extent, on working hours. Proxy reports do not differ significantly from a child's self-report. Further analysis demonstrates that survey design choices affect the coefficient estimates of some determinants of child labor in a child labor supply equation. The results suggest that low-cost changes to questionnaire design will potentially clarify the concept of work for respondents.     

What does Variation in Survey Design Reveal about the Nature of Measurement Errors in Household Consumption?

We randomly assigned eight different consumption surveys to obtain evidence on the nature of measurement errors in estimates of household consumption. Regressions using data from more error‐prone designs are compared with results from a ‘gold standard’ survey. Measurement errors appear to have a mean‐reverting negative correlation with true consumption, especially for food and especially for rural households.     

Methods of household consumption measurement through surveys: Experimental results from Tanzania

Surveys of consumption expenditure vary widely across many dimensions, including the level of reporting, the length of the reference period, and the degree of commodity detail. These variations occur both across countries and also over time within countries, with little current understanding of the implications of such changes for spatially and temporally consistent measurement of household consumption and poverty. A field experiment in Tanzania tests eight alternative methods of measuring household consumption, finding significant differences between consumption reported by the benchmark personal diary and other diary and recall formats. Under-reporting is particularly apparent for illiterate households and for urban respondents completing household diaries; recall modules measure lower consumption than a personal diary, with larger gaps among poorer households and for households with more adult members. Variations in reporting accuracy by household characteristics are also discussed and differences in measured poverty as a result of survey design are explored.     

The Impact of Women's Schooling on Fertility and Contraceptive Use: A Study of Fourteen Sub-Saharan African Countries

This article examines the relationship between female schoolingand two behaviors—cumulative fertility and contraceptiveuse—in fourteen Sub-Saharan African countries where Demographicand Health Surveys (DHS) have been conducted since the mid-1980s.Average levels of schooling among women of reproductive ageare very low, from less than two years to six. Controlling forbackground variables, the last years of female primary schoolinghave a negative relation with fertility in about half the countries,while secondary schooling is associated with substantially lowerfertility in all countries. Female schooling has a positiverelationship with contraceptive use at all levels. Among ever-marriedwomen, husband's schooling exerts a smaller effect than doesfemale schooling on contraceptive use and, in almost all cases,on fertility. Although the results suggest commonalities amongthese Sub-Saharan countries, they also reveal intriguing internationaldifferences in the impact of female schooling, which might reflectdifferences in the quality of schooling, labor markets, andfamily planning programs, among others.
