This paper aims to measure the time pattern of multiple and resurgent food scares and their direct and cross-product impacts on consumer response. The Almost Ideal Demand System (AIDS) is augmented by a flexible stochastic framework which has no need for additional explanatory variables such as a media index. Italian aggregate household data on meat demand is used to assess the time-varying impact of a resurgent BSE crisis (1996 and 2000) and the 1999 Dioxin crisis. The impact of the first BSE crisis on preferences seems to be reabsorbed after a few months. The second wave of the scare at the end of 2000 had a much stronger effect on preferences and the positive shift in chicken demand continued to persist after the onset of the crisis. Empirical results...

Rapid economic growth in China has resulted in substantially improved household incomes. Diets have also changed, with a movement away from traditional foods and towards animal products and processed foods. Yet micronutrient deficiencies, particularly for calcium and vitamin A, are still widespread in China. In this research we model the determinants of the intakes of these two micronutrients using household panel data, asking particularly whether continuing income increases are likely to cause the deficiencies to be overcome. Nonparametric kernel regressions and random effects panel regression models are employed. The results show a statistically significant but relatively small positive income effect on both nutrient intakes. The local availability of...

Nepal faces multiple development challenges, including chronic and widespread food insecurity and adult and child malnutrition. Due to population growth, agricultural stagnation and a range of institutional failures, the threat of a serious food crisis in Nepal is substantial. The recent scaling back of WFP assistance means that food security conditions in some parts of Nepal will undoubtedly worsen in the near future. This paper presents a brief review of topics and available evidence regarding food security, malnutrition and related subjects in Nepal. It is intended to document important source material and provide an overview of topics for non-specialists or those moving into new areas of concern.

This study analyzes difference in efficiency among the U.S. rural hospitals using a two-stage, semi-parametric approach. Data Envelopment Analysis is used in the first stage to calculate cost, technical and allocative efficiencies of Critical Access Hospitals (CAH) and non-CAH rural hospitals. Following Simar and Wilson (2007), bootstrapped truncated regressions are used in the second stage to infer on relationship between the cost, technical and allocative inefficiencies of hospitals and some environmental variables. The estimated results show that CAHs are less cost, technical and allocative efficient than non-CAH rural hospitals. The results also show that Medicare cost-based reimbursement for CAHs has a negative effect on the efficiency of these...

Background: The Inner City Asthma Intervention (ICAI) was a national multi-center implementation of an evidence-based intervention to reduce asthma morbidity. Objective: This study describes mitigating behaviors and reported outcomes in families with asthma who completed the intervention and a post-intervention survey at one of the ICAI sites. Results: Eighty percent (0.72- 0.88, 95% confidence interval) of these families made five or more changes to mitigate exposure to environmental asthma triggers. The majority of families (0.84-0.96, 95% confidence interval) reported an improved awareness of asthma symptoms and less school absences, limitations of activity, unplanned doctor visits, and asthma related sleep disruption.

Calories, Obesity and Health in OECD Countries

Mazzocchi, Mario; Traill, W. Bruce.

Theoretical models suggest that decisions about diet, weight and health status are endogenous within a utility maximisation framework. In this paper, we model these behavioural relationships in a fixed-effect panel setting using a simultaneous equation system, with a view to determining whether economic variables can explain the trends in calorie consumption, obesity and health in OECD countries and the large differences among countries. The empirical model shows that progress in medical treatment and health expenditure mitigates mortality from diet-related diseases, despite rising obesity rates. While the model accounts for endogeneity and serial correlation, results are affected by data limitations.

The conventional computational algorithms for full information maximum likelihood (FIML) estimation of the censored probit model (see Farber, 1983), will sometimes fail to converge when the estimated value of the correlation coefficient (ñ) approaches ±1; even when the true value of ñ is not at a boundary. We show that a simple reparametrization of the censored probit model may afford straightforward Newton-Raphson convergence to the true FIML estimate for cases in which likelihood maximization under the conventional censored probit parameterization would have failed. Moreover, our method avoids the computational and inferential complications that arise in alternative methods that, based on a specified criterion, suggest fixing the estimated value of ñ at...

Comparing Predictors of Diet Quality in Canada Over Time Under Consideration of Altering Food Guides

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...

Consumer incentives to comply with nutritional recommendations – an economic approach

Dejgaard Jensen, Jorgen; Hansen, Aslak H.; Fagt, Sisse; Velsing Groth, Margit.

Inappropriate diets have been found to cause long-term health problems in most industrial and post-industrial countries worldwide. Despite the existence of dietary guidelines in many countries – and widespread familiarity with these guidelines – large shares of the populations do not comply with these guidelines. The objective of the paper is to investigate economic explanations for non-compliance quantitatively, focusing on consumers’ perceived value of reduced freedom of choice, if they should comply with the dietary recommendations. The paper establishes and econometric simulation model for Danish food consumers, which is used for calculating these economic welfare losses, as well as the contribution to these losses from individual recommendations....

Smed, Sinne; Hansen, Lars Garn.

In modern societies it seems that the pleasures of taste often encourage the consumption of fatty, salty and sweet foods, whereas growing health awareness discourages consumption of the same foods. Numerous studies find that education and diet healthiness are highly correlated and one possible explanation is that consumers with a longer education are better at understanding and appreciating the health implication of their diet than are consumers with a short education. In this study we estimate a hedonic model of consumer’s valuation of food characteristics that allows nutrients to influence utility both through their perceived effects on health and their effects on the taste of food. The model is estimated using purchase data from a consumer panel with...

Consumer valuation of health attributes in food

Smed, Sinne; Hansen, Lars Garn.

In modern societies consumers often face a trade-off between health and taste, the latter which encourages consumption of fatty, salty and sweet foods, whereas health awareness discourages consumption of the same food. The resulting diet, often rich in calories, sweeteners and fat constitutes a threat to public health as poor nutrition has been linked to several types of cancer, cardiovascular disease, diabetes, and osteoporosis as well as overweight and obesity. In this study we use the hedonic model as an outset to model consumer valuation of nutritional and non-nutritional characteristics of food consumption in a consistent way, accounting for that nutrients might influence utility both through health and through taste. This implies that a given...

Constructing a theoretical framework and using a survey data of 294 customers from 25 supermarkets in Beijing, this paper studies the willingness to pay (WTP) for additive-free Mooncakes in Beijing and finds that age and income are important for WTP for “food safety” in China. Income is positively correlated with the WTP and there is an inverted-U-shaped relationship between age and WTP. This study indicates that consumers in Beijing are willing to pay 5.80 Yuan more for an additive-free Mooncake, which provides a good policy benchmark for the government regulation on food additives. Furthermore, the theoretical framework also provides a good benchmark for understanding WTP in the future study of food safety.

This paper addresses an important but not widely investigated question of how calorie consumption in African low income households would respond to intra-household redistribution of income from men to women. Specifically, I use survey data on a sample of 480 households from semi-rural areas of south-western Nigeria to analyze the response of per capita calorie intake to changes in women’s share of household income, after controlling for per capita income and demographic characteristics at individual, household and community levels. I also examine the effect of marginal increases in household income on per-capita calorie intake conditional on the income distribution factor, women’s share of income. My results suggest that redistributing household income...

This paper investigates the role that aspects of the physical environment play in determining health outcomes in adults as measured by body mass index (BMI). Using spatial econometric techniques that allow for spatial spillovers and feedback processes, this research specifically examines how differing levels of access to large chain grocers has on individual health outcomes. While other studies have investigated the impact of proximity to food retailers, the point-coordinate data used in this paper is uniquely suited to spatial econometric estimation at the individual level. In addition to modeling spatial dependence and allowing for unobserved neighborhood effects, the flexibility of the model is increased by incorporating potential spatial...

This study considers the links between primary indicators of health and individual labor productivity in Colombia and explores how additional public expenditures on health may improve individuals health. Sample statistics show that illness occurs more frequently for women than for men, for less educated than for more educated, for rural than urban residents, and for older individuals. The well educated are considerably taller than those without schooling (6 cm. for males and 4 cm. for females). The empirical evidence confirms that health indicators are related to individual earnings in Colombia. A Mincerian log-earnings equation that includes health indicators as a form of human capital in addition to schooling is specified. When the morbidity variable is...

Research on malnutrition typically focuses on severe cases, where anthropometric status falls below or above an extreme threshold. Such categorization is necessary for clinicians since mild cases may not justify intervention, but researchers could find that changes in mild malnutrition convey valuable information about mortality risk and health status. This paper focuses on changes in both mild and severe underweight in young children, as measured by 130 DHS surveys for 53 countries over a period from 1986 to 2007. We find that counting variance in all forms of underweight provides closer correlations with aggregate health outcomes (the under-five child mortality rate), and is more closely correlated to several influences of malnutrition (national income,...
