A PROFILE OF POVERTY IN EGYPT: 1997 AgEcon
Datt, Gaurav; Jolliffe, Dean; Sharma, Manohar P..
This paper presents a profile of poverty in Egypt for 1997. It assesses the magnitude of poverty and its distribution across geographic and socioeconomic groups, provides information on the characteristics of the poor, illustrates the heterogeneity among the poor, and helps identify empirical correlates of poverty. The poverty profile is constructed using data from the recently completed Egypt Integrated Household Survey, a nationwide, multiple-topic household survey, carried out by the International Food Policy Research Institute in coordination with the Ministry of Agriculture and Land Reclamation and the Ministry of Trade and Supply. Reference poverty lines that take into account regional differences in food and nonfood prices, age and composition of...

Censored Quantile Regression and Purchases of Ice Cream AgEcon
Gustavsen, Geir Waehler; Jolliffe, Dean; Rickertsen, Kyrre.
The effects on purchases of ice cream of increasing the value added tax (VAT) for less healthy foods and removing the VAT for healthy foods are estimated. The effects on high- and low-purchasing households are estimated by using quantile regressions. Many households did not purchase ice cream and censored quantile regressions are estimated by a recently developed algorithm, which is simple, robust, and performs well near the censoring point. High-purchasing households will reduce their annual per capita purchases with 1.8 kilograms corresponding to an annual reduction of more than half a kilogram of body weight.

DETERMINANTS OF POVERTY IN EGYPT: 1997 AgEcon
Datt, Gaurav; Jolliffe, Dean.
Poverty profiles are a useful way of summarizing information on the levels of poverty and the characteristics of the poor in a society. They also provide us with important clues to the underlying determinants of poverty. However, important as they are, poverty profiles are limited by the bivariate nature of their informational content. The bivariate associations typical in a poverty profile can sometimes be misleading; they beg the obvious question of the effect of a particular variable conditional on the other potential determinants. While there may be certain contexts where unconditional poverty profiles are relevant to a policy decision (see Ravallion 1996), often one would be interested in the "conditional" poverty effects of proposed policy...

Do Income Constraints Inhibit Spending on Fruits and Vegetables Among Low-Income Households? AgEcon
Stewart, Hayden; Blisard, Noel; Jolliffe, Dean.
This study assesses whether income constraints inhibit spending on fruits and vegetables among low-income households. If this is the case, then it is hypothesized that the distribution of expenditures on fruits and vegetables by low-income households should be stochastically dominated by the distribution of expenditures on these same food items by other households. Moreover, it must be the case that low-income households would increase their spending on fruits and vegetables in response to an increase in their income. Using household data from the 2000 Consumer Expenditure Survey, a test of stochastic dominance is performed. Censored quantile regressions are also estimated at selected points of the conditional expenditure distribution. Low income...

ESTIMATING SAMPLING VARIANCE FROM THE CURRENT POPULATION SURVEY: A SYNTHETIC DESIGN APPROACH TO CORRECTING STANDARD ERRORS AgEcon
Jolliffe, Dean.
Essentially all empirical questions that are addressed with sample data require estimates of sampling variance. The econometrics and statistics literatures show that these estimates depend critically on the design of the sample. The sample for the U.S. Current Population Survey (CPS), which serves as the basis for official poverty, unemployment, and earnings estimates, results from a stratified and clustered design. Unfortunately, analysts are frequently unable to estimate sampling variance for many CPS statistics because the variables marking the strata and clusters are censored from the public-use data files. To compensate for this, the Bureau of Census provides a method to approximate the sampling variance for several, specific point estimates, but no...

FOOD STAMP BENEFITS AND CHILD POVERTY IN THE 1990s AgEcon
Jolliffe, Dean; Tiehen, Laura; Gundersen, Craig; Winicki, Joshua.
In 2000, 8.8 million children received food stamps, making the Food Stamp Program a crucial component of the social safety net. Despite its importance, little research has examined the effect of food stamps on children's overall well-being. Using the Current Population Survey from 1989 to 2001, we consider the impact of food stamps on three measures of poverty - the headcount, the poverty gap, and the squared poverty gap. These measures portray the incidence, depth, and severity of poverty. We find that in comparison to the headcount measure, food stamp benefits lead to large reductions in the poverty gap and squared poverty gap measures. We then simulate the effects of several changes in the distribution of food stamps and find that a general...

Let's Eat Out: Americans Weigh Taste, Convenience, and Nutrition AgEcon
Stewart, Hayden; Blisard, Noel; Jolliffe, Dean.
Whether eating out or buying carry-out, Americans are consuming more and more of their calories from full-service and fast-food restaurant fare. The share of daily caloric intake from food purchased and/or eaten away from home increased from 18 percent to 32 percent between the late 1970s and the middle 1990s, and the away-from-home market grew to account for about half of total food expenditures in 2004, up from 34 percent in 1974. Analysis of a survey of U.S. consumers indicates that respondents want convenience and an enjoyable dining experience, but the desire for health also plays a role as does diet-health knowledge.

LOW-INCOME HOUSEHOLDS' EXPENDITURES ON FRUITS AND VEGETABLES AgEcon
Blisard, Noel; Stewart, Hayden; Jolliffe, Dean.
This report analyzes fruit and vegetable expenditures by low-income households and higher income households, and compares the sensitivity of both groups' purchases to changes in income. On average, low-income households spent $3.59 per capita per week on fruits and vegetables in 2000 while higher income households spent $5.02-a statistically significant difference. In addition, a statistical demand model indicates that marginal increases in income received by low-income households are not spent on additional fruits and vegetables. In contrast, increases in income received by higher income households do increase their fruit and vegetable expenditures. One interpretation of this finding is that low-income households will allocate an additional dollar of...

Low-Income Households' Expenditures on Fruits and Vegetables AgEcon
Blisard, Noel; Stewart, Hayden; Jolliffe, Dean.
Both public and private organizations have noted that Americans generally eat less fruits and vegetables than is recommended in the Food Guide Pyramid. For example, the Produce for Better Health Foundation found that only 38 percent of Americans consume the recommended number of servings of vegetables, while only 23 percent consume the recommended number of servings of fruit. Even more troubling, low-income households eat even less fruits and vegetables than higher income households.

The Cost of Living and the Geographic Distribution of Poverty AgEcon
Jolliffe, Dean.
The prevalence of poverty has been greater in nonmetro areas than in metro areas in every year since the 1960s when poverty rates were first officially recorded. Accordingly, Federal funds for social assistance programs and community development have favored nonmetro areas. This study suggests that adjusting poverty measures to account for cost-of-living differences between metro and nonmetro areas reverses that ranking. Once adjusted for cost-of-living differences using the Fair Market Rents index, metro poverty is greater than nonmetro poverty in terms of prevalence, depth, and severity over the entire 1991-2002 study period.

The Demand for Food Away from Home: Do Other Preferences Compete with Our Desire to Eat Healthfully? AgEcon
Stewart, Hayden; Blisard, Noel; Jolliffe, Dean; Bhuyan, Sanjib.
Health-oriented government agencies have had limited success at encouraging Americans to eat a healthful diet. One reason may be that other preferences compete with our desire to eat healthfully. We explore the effect of consumer preferences on the demand for food away from home, including frequency of eating out and choice of outlet type. Preferences for convenience and ambience are found to influence behavior. Furthermore, omitting these variables from econometric models can bias the estimated effect of preferences for a healthful diet.

The Income Gradient and Distribution-Sensitive Measures of Overweight in the U.S. AgEcon
Jolliffe, Dean.
This paper considers alternate measures of overweight in the U.S. that are sensitive to changes in the body-mass index (BMI) distribution, more robust to measurement error and continuous in the body-mass index (BMI) at the overweight threshold. The measures suggest that standard prevalence rates may be understating the severity of the problem. Since 1971, overweight prevalence has increased by 40% while the distribution-sensitive measure has increased by 174%. They also provide some useful insight into socioeconomic differences in overweight. For example, overweight prevalence rates for the poor and the rich have been very similar over the last 30 years, with the rich have a slightly higher rate in the most recent 2001- 2002 data. In contrast, the...

Whose Education Matters in the Determination of Household Income: Evidence from a Developing Country AgEcon
Jolliffe, Dean.
This paper aims to answer how best to model education attainment, which is an individual-level variable, in household-level income functions. The accepted practice in the literature is to use the education level of the household head. This paper compares the head-of-household model to three competing models and concludes that the maximum or average level of education in the household is a better explanatory variable of household income. Least absolute deviations (LAD) estimators and censored least absolute deviations (CLAD) estimators are used to predict income. Standard errors, which are robust to violations of homoscedasticity and independence, are generated by a boot-strap method that replicates the two-stage sample design.
