A survey-based choice experiment on coca cultivation

From 1997 to 2005, an astonishing 5200 million USD was invested to reduce cocaine production in Colombia, the world's main cocaine producer. However, little is known about the effectiveness of policies targeting coca cultivation. This paper uses a survey-based experiment to evaluate the effects of the two main policies: eradication and alternative development programs. Our results support Becker's (1968) model of crime participation and in addition shed light on other non-monetary factors that affect the coca cultivation decision: religion, legitimacy, remoteness, and poverty are found to be important. We find that coca cultivation is inelastic to increases in perceived risk and relative profit so eradication and alternative development would have a rather small effect on coca cultivation. A simple simulation exercise predicts that investing additional hundred thousand dollars in eradication decreases coca cultivation in only 1.5%.     

Impact of Low‐Skilled Immigration on Female Labour Supply

In this paper, segmenting the market by educational levels, we investigate which native‐born women are more affected by an increase of low‐skilled immigrants working in the household service sector. We present a model of individual choice with home production and, using a harmonized dataset (the Cross‐National Equivalent File), we estimate its main comparative static results. The results suggest that the share of immigrants working in services is positively associated with an increase of native‐born women's labour supply at the intensive margin, if skilled, and at the extensive margin, if unskilled. Moreover, the results show that these effects are larger in countries with less‐supportive family policies.     

The incremental time costs of children: An analysis of children's impact on adult time use in Australia

Abstract

Raising children takes both time and money. Scholars have sought convincing ways to capture the costs of children, but even when these estimates include indirect costs, such as mothers' foregone earnings, they fall short of the true time costs involved. This paper uses data from the 1997 Australian Bureau of Statistics (ABS) Time Use Survey to study how the allocation of time differs across households with varying numbers and ages of children and how households with children differ from those without children. It also examines the intra household division of time resources, showing how childcare, related unpaid work, and the total market and non-market workloads compare for a couple in the same household. It includes secondary activity in an analysis of total parental time commitments to give a more accurate picture of the time cost of children than is possible on the basis of analyzing “primary” activities alone.     

Micro and macro elasticities in a life cycle model with taxes

We build a life cycle model of labor supply that incorporates changes along both the intensive and extensive margin and use it to assess the consequences of changes in tax and transfer policies on equilibrium hours of work. We find that changes in taxes have large aggregate effects on hours of work. Moreover, we find that there is no inconsistency between this result and the empirical finding of small labor elasticities for prime age workers. In our model, micro and macro elasticities are effectively unrelated. Our model is also consistent with other cross-country patterns.     

Coca Substitution and Free Trade in Bolivia: The Pending Crisis

This paper uses the factors proportion model of production and trade with ten inputs to analyze the potential impact of the Free Trade Agreement of the Americas (FTAA) on the coca substitution program in Bolivia. With six crops including coca, the model produces comparative statics elasticities of changing prices on factor prices and output. Results show that the coca substitution program with free trade will result in large income redistribution in the coca‐producing region as a result of increased competition from larger and more efficient economies. Increased subsidies and institutional changes will be needed to sustain the coca substitution program in the long run.     

Fertility,household structure,and parental labor supply: Evidence from China

This study examines the effects of fertility on household structure and parental labor supply in China. To solve the endogeneity problem, we use a unique survey on households with twin children and a comparison group of non-twin households. The ordinary least squares estimates show a negative correlation between fertility and parental labor supply in rural China. Using twinning as a natural experiment, we do not find evidence on the negative effects of fertility on parental labor supply. By contrast, we find that the twinning-induced increase in fertility significantly enhances the coresidence of grandparents in rural China. We suggest that the negative effects of fertility on parental labor supply are mitigated by the childcare provided by grandparents in rural China. We also find that fertility does not induce coresidence of grandparents in urban China. Our results have important implications for population and public childcare policies.     

Do household definitions matter in survey design? Results from a randomized survey experiment in Mali

Household definitions used in multi-topic household surveys vary between surveys but have potentially significant implications for household composition, production, and poverty statistics. Standard definitions of the household usually include some intersection of keywords relating to residency requirements, common food consumption, and intermingling of income or production decisions. Despite best practices intending to standardize the definition of the household, it is unclear which types of definitions or which intersections of keywords in a definition result in different household compositions. This paper conducts a randomized survey experiment of four different household definitions in Mali to examine the implications for household-level statistics. This approach permits analysis of the trade-offs between alternative definition types. We find that additional keywords in definitions increase rather than decrease household size and significantly alters household composition. Definitions emphasizing common consumption or joint production increase estimates of the levels of household assets and consumption statistics, but not on per adult equivalency asset and consumption statistics, relative to open-ended definitions of the household. In contrast, definition type did not affect production statistics in levels, though we observe significant differences in per adult equivalency terms. Our findings suggest that variations in household definition have implications for measuring household welfare and production.     

Doing it all: Women’s employment and reproductive work in Tajikistan

Central Asia has low labor force participation rates for women, despite high levels of poverty in the non-oil producing countries. Female labor force participation is related to competing uses for women’s time, especially in a context of poor infrastructure and limited availability of purchased replacements for household labor. We examine factors affecting women’s participation in employment and reproductive household work in Tajikistan, drawing on the 2003 Tajikistan Living Standards Survey. We incorporate specific conditions in Central Asia, including the prevalence of extended family households, norms about how women share household work, an absence of market substitutes for caring and reproductive labor, employment in family enterprises and poor infrastructure, especially in rural areas. We estimate the system using a Generalized Maximum Entropy (GME) approach. We find that few individual and household characteristics are related to time in employment. Time in noncare reproductive work decreases if a woman receives direct remuneration for her employment (compared to working in a family farm or enterprise but receiving no direct remuneration), but increases if the woman has less access to infrastructure. Rural women spend more time in both employment and non-care reproductive work than urban women, but less time in care work. Lack of infrastructure may leave women with few choices with respect to non-care reproductive work, while overall levels of time poverty create pressures on care time.     

The impact of fiscal policies on agricultural household decisions

This paper provides a comparative static analysis of farm household's production, consumption, and labor market decisions under alternative tax policies. We explore the implications of non-separable household decisions caused by widespread non-participation in labor, land, financial and/or food markets, as is typical of low income economies. The analytical results indicate that when labor market imperfections occur, most tax-induced responses are ambiguous, mainly due to shadow price effects. This is particularly the case for the labor market and production responses to most tax tools under study, while a decreasing demand for consumption goods appears to be the result in several cases. Furthermore, tax-induced allocation effects may differ between the non-separable and the separable model versions, indicating the potential impact of labor market constraints on farm household responses to tax policies. In particular, standard taxes as well as a land tax may imply production adjustments in the case of non-separability.     

Identifying non-cooperative behavior among spouses: Child outcomes in migrant-sending households

I propose a model of household decision-making under asymmetric information and show that resulting allocations may not be fully cooperative. The model yields a simple test for cooperative decision-making, which I apply to data from China. I find that, when the father migrates without his family, children spend more time in household production, while mothers spend less time in both household production and income-generating activities. This is not consistent with standard cooperative models of the household: simply reallocating time to compensate for the father's absence would cause an increase in household labor for both children and mothers and, if migration occurs in response to a negative shock, we should observe an increase in mothers' time in income-generating activities rather than a reduction. The results also do not appear to be driven by an increase in mothers' bargaining power, as children's human capital is not affected by migration, controlling for income.     

Spending Time and Money within the Household*

We consider, both theoretically and empirically, the allocation of time and money within the household. The research question is whether a married person who enjoys more leisure than their partner also receives more consumption (which seems to indicate the outcome of power within the household) or receives less consumption (which seems to indicate differing intrahousehold preferences). We develop a simple parametric structural model with household production that is tested on survey data. We find that relative wages have an impact on power. For leisure, this effect is dominated by a conventional wage effect, in which the partner who has the higher wage takes less leisure.     

Worker Absenteeism in Search Equilibrium*

In this paper we introduce a general equilibrium model of search unemployment that incorporates absence from work as a distinct labor force state. Absenteeism is driven by random shocks to the value of leisure that are private information to the workers. Firms maximize profits while recognizing that the compensation package may affect the queue of job applicants and the absence rate. The analysis provides results concerning the effects of social insurance benefits and other determinants of workers' and firms' behavior. The normative analysis identifies externalities associated with firm‐provided sick pay and examines the welfare implications of alternative policies.     

Loafing or learning?—the demand for informal education

Using detailed time use data for Germany a positive correlation is found between the level of schooling and time investments in informal education. Two hypotheses explain this observation: (1) highly educated people have higher opportunity costs of their leisure time and thus prefer leisure activities which add to their market productivity (wage effect) and (2) highly educated people have a preference for ‘high quality’ leisure (taste effect). The demand for informal education is derived in a household production model accounting for both explanations. An empirical investigation finds evidence for both effects with the taste effect being more important.     

Has Abe's Womanomics Worked?

The present paper estimates the effect of the Abe Cabinet's Womanomics policies that aimed to increase female labor supply and keep women on a career path. The policies are surveyed, and the effects are estimated using microdata from the Labor Force Survey combined with data at the prefectural level on day care provision. A difference‐in‐difference (DD) method is applied to uncover the impacts of the Abe Cabinet's policies. The rapid increase in the provision of infant care, especially in the urban area, has contributed to a strong increase in the labor participation of mothers with young children. In addition, DD method estimates show a strong increase in mothers with infants staying in permanent‐contract regular employment. A significant shortening of work hours of workers, especially of parents with infants, is observed, which enabled working mothers to maintain their employment status. A change in the gender wage gap in the Japanese labor market is observed, but much progress is still required to close the large wage gap.     

Optimal income taxation when couples have endogenous bargaining power

This study examines the optimal income taxation for a two-earner household, where the couple bargains over their private goods consumption and time allocation between work and leisure. In the model, bargaining power is determined endogenously by the income gap between the two earners. Conventional studies have shown that the higher income tax rate should be imposed on the individual with the smaller wage elasticity, typically the individual with the higher productivity. In contrast to conventional argument, this study shows that the optimal tax rate on the household member with the higher productivity is lower than that of the individual with the lower productivity if the required tax revenue is relatively small and the influence of the gender income gap on the power balance of the couple is moderate. This is because such a tax structure encourages the labor supply of the individual with the higher productivity to mitigate the decrease in the household’s consumption induced by income taxation.     

SELF‐REPORTED ECONOMIC CONDITION AND HOME PRODUCTION: INTRA‐HOUSEHOLD ALLOCATION IN ITALY

This paper applies a collective model of intra‐household welfare distribution using individual self‐reported data. The model accounts for household production, and self‐reported information on economic condition is used to identify the sharing rule governing the bargaining process in the family. The theoretical framework implies a broad concept of full income, which includes household production as time allocated to domestic activities. We find that self‐reported data on economic status are useful in recovering individual shares of household income and that both wages and non‐strictly‐economic individual variables play an important role in the bargaining process determining the sharing rule in Italy.     

Diligence and laziness in chinese agricultural production teams

A simple numerical game-theoretic framework is used to explore the effects of rising work disutility on individual household work effort decisions in Chinese agricultural production teams. Effects of changes in the importance of distribution ‘according to labor’, concern for other members of the team, and peer pressure on team work performance are discussed, and resolution of a ‘prisoner's dilemma’ situation is shown to be central to the eventual outcome.     

Estimating direct and indirect rebound effects for U.S. households with input–output analysis Part 1: Theoretical framework

This is the first part of a two-part paper providing an analytical model of the indirect rebound effect, given a direct rebound estimate, that integrates consumer demand theory with the embodied energy of household spending from environmentally-extended input–output analysis. The second part applies the model developed in part one to simulate the direct and indirect rebound for the average U.S. household in terms of primary energy, CO₂e, NO_x, and SO₂ emissions and for energy efficiency investments in electricity, natural gas, or gasoline services. Part one provides a critical review of the largely independent economic and industrial ecology literatures on the indirect rebound. By studying the two-goods case and the n-goods case, we demonstrate that the indirect rebound is bounded by the consumer budget constraint, and inversely related to the direct rebound. We also compare the common proportional spending and income elasticity spending assumptions with our model of cross-price elasticities including both substitution and income effects for the indirect rebound. By assuming zero incremental capital costs and the same embodied energy as conventional technologies for efficient appliances, we model an upper bound of the indirect rebound. Future work should also consider the increase in consumer welfare possible through the rebound effect.     

Child labor and the minimum wage: Evidence from India

This study examines how changes in the minimum wage affect child labor in India. The analysis uses repeated cross sections of India's NSSO employment data from 1983 to 2008 merged with data on state-level minimum wage rates. Theoretically, the impact of the minimum wage on child work could go either way, so empirical evidence from a country with high rates of child labor and a myriad of minimum wage laws across states and industries helps to lessen the ambiguity. Results indicate that regardless of gender, in urban areas, a higher minimum wage reduces child labor in household work. In rural areas a similar result applies for girls while household labor does rise for boys. The minimum wage has virtually no impact on child work outside of the home across urban and rural areas.     

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.
