Smallholders' Cost Efficiency in Mozambique: Implications for Improved Maize Seed Adoption 31
Zavale, Helder; Mabaya, Edward T.; Christy, Ralph D..
Maize is an important staple in Mozambique. It is also a dominant crop produced by smallholder farmers. However, the actual maize yields, currently estimated at 1.4 tons/ha, fall short of potential yields of 5-6.5 tons/ha. With population growth rate increasingly exceeding agricultural (and maize) productivity growth rate, the government of Mozambique faces a serious problem of food insecurity and poverty alleviation. This study examines cost inefficiency among smallholder maize farmers in Mozambique, and the impact of improved maize seed adoption on cost efficiency. A Translog functional form is used to estimate the frontier cost function. A cost-inefficiency function is used to examine the factors that determine cost inefficiency among farmers....

Estimation of Treatment Effect of Asthma Case Management Using Propensity Score Methods 31
Brandt, Sylvia J.; Gale, Sara; Tager, Ira.
Objective: To estimate the treatment effect from participating in an asthma intervention that was part of the National Asthma Control Program. Study Setting: Data on children who participated in asthma case management (N=270) and eligible children who did not participate in case management (N=2,742) were extracted from a claims database. Study Design: We created 81 measures of health care utilization and 40 measures of neighborhood characteristics that could be related to participation in the program. The participation model was selected using the cross-validation-based Deletion Substitution and Addition (DSA) algorithm. We used optimal full matching for the vector of Mahalanobis’ distances and propensity scores to estimate the difference between...

Eating Out in the British Isles 31
Keelan, Conor D.; Henchion, Maeve M.; Newman, Carol F..
This paper presents a comparative analysis of the foodservice industries in both Ireland and the UK. Each industry is analysed separately using the most recently available Household Budget Survey datasets for Ireland and the most recent Expenditure and Food Datasets for the UK and is disaggregated into quick-service (fast food and takeaway) and full-service (hotel and restaurant meals), the two largest components of each industry. A double hurdle model, adjusted for misspecification, is used in this analysis. A number of variables affect both dependent variables in the same way, for example, income and age and the number of workers variable, but differences are apparent throughout the discussion. Perhaps the most interesting point to highlight is how...

Relative Income, Network Interactions and Social Stigma 31
Chen, Xi; Zhang, Xiaobo.
Blood donation with compensation is considered as a social stigma. However, more people in the reference group donate blood often leads to less moral concern and more followers. Therefore, the behavior is likely to be influenced through one’s interactions with neighbors, friends and relatives. Meanwhile, relative income may affect the motives for blood donation through increasing mistrust and stress. The motives might be stronger for households of lower social rankings. Utilizing three-wave census-type panel data in 18 villages in rural western China, two identification strategies, instrumental variable and network-based identification, are implemented to estimate the effect of social interactions. Both community-specific and household-specific relative...

Intrahousehold Resource Allocation in Cote D'Ivoire: Social Norms, Separate Accounts and Consumption Choices 31
Duflo, Esther; Udry, Christopher R..
In Cote d'Ivoire, as in much of Africa, husbands and wives farm different crops on separate plots. These different crops are differentially sensitive to particular kinds of rainfall shocks. We find that conditional on overall household expenditure, the composition of expenditure is sensitive to the gender of the recipient of a rainfall shock. For example, rainfall shocks associated with high women's income shift expenditure towards food. Social norms constrain the use of profits from yam cultivation, which is carried out by men. Correspondingly, we find that rainfall-induced fluctuations in income from yams are transmitted to expenditures on education and food, not to expenditures on private goods. We reject the hypothesis of complete insurance within...

Labor Market Participation of Chinese Agricultural Households 31
Glauben, Thomas; Herzfeld, Thomas; Wang, Xiaobing.
This work is devoted to the analysis of the different labor market participation regimes of Chinese farm households. Using household data over the period 1986-2000 from the province Zhejiang, we apply a multinomial logit model to empirically examine household, farm, and regional characteristics affecting the probability that farmers employ one of four alternative labor market regimes. Results suggest that labor market decisions are significantly related to several personal, farm, and village attitudes. In addition, we find the more market oriented policy reforms at the end of the 1980s stipulated that households participate in labor markets while the more anti-market reforms during the 1990s led to the opposite and encouraged autarky.

Panel Data Evidence on the Determinants of Non-Timber Forest Products Extraction: The Case of Xate in Mexico 31
Lopez-Feldman, Alejandro.
This paper examines the determinants behind households' decisions regarding non-timber forest products extraction. Data from Mexico is used to estimate a selection model. Results show that individuals with low levels of human capital are more likely to extract than other individuals; the same is true for individuals from poor households.

Intra-Household Resource Management Structure and Income-Hiding under Incomplete Information 31
Castilla, Carolina.
There is evidence that some multi-person households may withhold income transfers, such as bonuses, gifts, and cash transfers, from other members of the household (Ashraf (2009); Vogler and Pahl, (1994)). In this paper, I show that the incentives to hide income under incomplete information regarding the quantity of resources available to the household differ for three different household resource management structures. I illustrate this with a simple two-stage game. In the first stage, one spouse receives a monetary transfer that is unobserved by her spouse, and she must decide whether to reveal or to hide it. In the second stage, spouses bargain over the allocation of resources between a household good and private expenditure. The three models differ in...

Comparing Predictors of Diet Quality in Canada Over Time Under Consideration of Altering Food Guides 31
Drescher, Larissa S.; Goddard, Ellen W..
Latest data on the diet of Canadians from the Canadian Community Health Survey reveals that the diet quality of Canadians needs improvement. Within this paper predictors of diet quality in Canada are identified based on two cross-sectional data sets from the Canadian Food Expenditure Survey. To measure diet quality, the Canadian Healthy Food Diversity (CanHFD)-Index is developed which is based on Food Guide recommendations. Moreover, this paper considers that the Food Guide between survey years has changed when analyzing diet quality. To track changes in demand for diet quality we use “Canada’s Food Guide 1982” to calculate CanHFD-Index for 1984 and 1996. Changes in demand for diet quality according to “Canada’s Food Guide to Healthy Eating 1992” are...

Population and Health Policies 31
Schultz, T. Paul.
The literature evaluating population and health policies is in flux, with many disciplines exploring biological and behavioral linkages from fetal development to chronic disease, disability, and late life mortality. The focus here is on research methods, findings, and questions that economists can clarify regarding the causal relationships between economic development, health outcomes, and reproductive behavior, which operate in many directions. The connection between conditions under which people live and their expected life span and health status refer to “health production functions”. The relationships between an individual’s stock of health and productivity, well being, and life span encompasses the “returns to health human capital”. The control of...

A double-hurdle model of Irish households' foodservice expenditure patterns 31
Keelan, Conor D.; Henchion, Maeve M.; Newman, Carol F..
The aim of this paper is to analyse the various factors fuelling demand for Food- Away - From- Home (FAFH) in Ireland. The two largest components of this industry, the quick- service sector (fast food and takeaway) and the full- service sector (hotel and restaurant meals), are analysed using the most recently available Household Budget Survey data for Ireland. The results from a Box- Cox double hurdle model indicate that different variables affect expenditure in the different sectors in different ways. Income has a greater effect on full- service expenditure than on quick- service. Similarly households that are healthconscious indicate a greater preference for full- service meals while households with higher time values indicate a greater preference for...

Are Household Production Decisions Cooperative? Evidence on Pastoral Migration and Milk Sales from Northern Kenya 31
Doss, Cheryl R.; McPeak, John G..
Market-based development efforts frequently create opportunities to generate income from goods previously produced and consumed within the household. Production within the household is often characterized by a gender and age division of labor. Market development efforts to improve well being may lead to unanticipated outcomes if household production decisions are non-cooperative. We develop and test models of household decision-making to investigate intra-household decision making in a nomadic pastoral setting from Kenya. Our results suggest that household decisions are contested, with husbands using migration decisions to resist wives’ ability to market milk.

Fertility in Developing Countries 31
Schultz, T. Paul.
The associations between fertility and outcomes in the family and society have been treated as causal, but this is inaccurate if fertility is a choice coordinated by families with other life-cycle decisions, including labour supply of mothers and children, child human capital, and savings. Estimating how exogenous changes in fertility that are uncorrelated with preferences or constraints affect others depends on our specifying a valid instrumental variable for fertility. Twins have served as such an instrument and confirm that the cross-effects of fertility estimated on the basis of this instrument are smaller in absolute value than their associations.

Agriculture, Income Risks and Rural Poverty Dynamics: Strategies of Smallholder Producers in Kenya 31
Kuyiah, Joanne Wasswa; Obare, Gideon A.; Herrero, Mario; Waithaka, Michael M..
Poverty in Kenya has been on the increase over the last decade. It is estimated that 56% of the total population live in absolute poverty. Most of the poor reside in rural areas where agriculture is the main livelihood activity. Majority of Kenya's farmers are smallholders. They account for 75% of the total agricultural output and about 70% of marketed agricultural produce. The fate of smallholder agriculture in this country is therefore central to poverty reduction. A collapse in output and incomes from smallholder agriculture is likely to have damaging welfare effects and retard pro-poor economic growth. Smallholders often operate in a risky environment, which affects the level and variability of household resource endowments and income. The importance...

Intra-Household Redistribution of Income and Calorie Consumption in South-Western Nigeria 31
Aromolaran, Adebayo B..
This study investigates how per capita calorie intake in low income households of rural southwestern Nigeria responds to changes in total household income and women’s share of household income. The study addresses two major questions. First, is calorie-income elasticity large enough to justify the use of income increases as a food/nutrition policy strategy for increasing calorie intake among low income households? Second, what is the potential effect of intra-household redistribution of income from men to women on per capita calorie consumption? My results show that calorie-income elasticity is small and close to zero, implying that income policies may not be the most effective way to achieve substantial improvements in calorie consumption. I also find...
