AN EVALUATION OF THE USDA FOOD SECURITY MEASURE WITH GENERALIZED LINEAR MIXED MODELS AgEcon
Opsomer, Jean D.; Jensen, Helen H.; Pan, Suwen.
Over the last decade, new information has been developed and collected to measure the extent of food insecurity and hunger in the United States. Common measurement of the phenomenon of hunger and food insecurity has become possible through efforts of the U.S. Department of Agriculture (USDA) to develop a set of survey questions that can be used to obtain estimates of the prevalence and severity of food insecurity. This paper takes a closer look at the measurement of food insecurity and the effect of household variables on measured food insecurity. The effects of demographic and survey-specific variables on the food insecurity/hunger scale are evaluated using a generalized linear model with mixed effects. Data come from the 1995, 1997, and 1999 Food...

Behavioral Economics, Food Assistance, and Obesity AgEcon
Just, David R..
While there is mixed evidence of the impact of food assistance programs on obesity, there is general agreement that the food-insecure are at higher risk of obesity and obesity-related diseases. Food assistance programs, originally designed to overcome a lack of available food, now need to confront a very different problem: how to provide for the food-insecure while encouraging healthy lifestyles. This paper examines the potential to address these competing needs using traditional economic policies (manipulating information or prices) versus policies engaging behavioral economics and psychology.

Characteristics of Low-Income Households With Very Low Food Security: An Analysis of the USDA GPRA Food Security Indicator AgEcon
Nord, Mark.
This Economic Information Bulletin describes characteristics of low-income households that had very low food security in 2005. The U.S. Department of Agriculture monitors the food security of low-income households to assess how effectively the Government’s domestic nutrition assistance programs meet the needs of their target populations. USDA seeks to reduce the prevalence of very low food security among low-income households as part of its strategic plan under the Government Performance and Results Act (GPRA).

Do Food Prices Affect Food Security? Evidence from the CPS 2002-2006 AgEcon
Gregory, Christian A.; Coleman-Jensen, Alisha.
In this paper, we estimate the effect of food prices on food insecurity for SNAP recipients using data from the Current Population Survey and the recently published Quarterly Food At Home Price Database. We form a local food price index based on amounts of food for a household of four as established by the Thrifty Food Plan. We use an econometric model that accounts for the endogeneity of SNAP receipt to food insecurity and for household-level unobservables. We find that the average effect of food prices on the probability of food insecurity is positive and significant: an increase of one standard deviation in the price of our food basket is associated with an increase in food insecurity of between 1.3 and 2 percentage points for SNAP households. These...

Does SNAP Decrease Food Insecurity? Untangling the Self-Selection Effect AgEcon
Nord, Mark; Golla, Anne Marie.
Self-selection by more food-needy households into the Supplemental Nutrition Assistance Program (SNAP, formerly called the Food Stamp Program) makes it difficult to observe positive effects of the program in survey data. This study investigates self-selection and ameliorative program effects by examining households’ food security month by month for several months prior to initial receipt of SNAP benefits and for several months after joining the program. Two-year panels are constructed by matching the same households interviewed in the Current Population Survey Food Security Supplement in 2 consecutive years using data from 2001 to 2006. Food security is observed to deteriorate in the 6 months prior to beginning to receive SNAP benefits and to improve...

Does the Food Stamp Program Affect Food Security Status and the Composition of Food Expenditures? AgEcon
Pan, Suwen; Jensen, Helen H..
This article considers interaction among participation in the Food Stamp Program (FSP), food security status, and the composition of food expenditures. A quadratic almost ideal demand system with a bootstrapping two-step method of estimation is applied to data from the Current Population Survey–Food Security Supplement data and used to estimate the model and account for endogeneity between the FSP participation and food insecurity. The results show that FSP participation is endogenously related with food security status and significantly affects total food expenditure and food-away-from-home expenditures.

DYNAMICS OF POVERTY AND FOOD SUFFICIENCY AgEcon
Ribar, David C.; Hamrick, Karen S..
This study examines dynamics in poverty and food insufficiency using newly available longitudinal data from the 1993 panel of the Survey of Income and Program Participation SIPP) and the follow-on Survey of Program Dynamics (SPD). The study uses these data to characterize the incidence and dynamics of poverty and food problems for the entire U.S. population and for different subgroups. It also estimates multivariate, discrete-choice regression models to examine the factors associated with transitions into and out of poverty and food insufficiency, and it analyzes the empirical results in the context of a life-cycle model of income and food consumption. Results indicate that the incidence of food insufficiency in the United States is low-less than 3 percent...

Eliminating Fruit and Vegetable Planting Restrictions: How Would Markets Be Affected? AgEcon
Johnson, D. Demcey; Krissoff, Barry; Young, C. Edwin; Hoffman, Linwood A.; Lucier, Gary; Breneman, Vincent E..
Eighty-nine percent of American households were food secure throughout the entire year in 2005, meaning that they had access, at all times, to enough food for an active, healthy life for all household members. The remaining households were food insecure at least some time during that year. The prevalence of food insecurity declined from 11.9 percent of households in 2004 to 11.0 percent in 2005, while the prevalence of very low food security remained unchanged at 3.9 percent. This report, based on data from the December 2005 food security survey, provides the most recent statistics on the food security of U.S. households, as well as on how much they spent for food and the extent to which food-insecure households participated in Federal and community food...

Emerging Challenges for Food and Nutrition Policy in Developing Countries AgEcon
Stamoulis, Kostas G.; Pingali, Prabhu L.; Shetty, Prakash.
As the income and the average caloric intake of developing country populations increase, a relative shift in diets is taking place. The general pattern of change can be described as a shift towards more 'westernized' diets and away from traditional ones. Accompanying this dietary trend are the substantial and rapid changes in food production, retailing and distribution systems. After reviewing these combined shifts and changes, the paper discusses the implications for rural poverty and food security, food safety and quality but also for diet-related non-communicable diseases and the related, emerging challenges for policymakers.

Exploring definitions of food insecurity and vulnerability: time to refocus assessments AgEcon
Hart, Tim G.B..
Recent high food prices and changes in the world food situation are exacerbating the conditions of households that are vulnerable to food insecurity, especially those with weak livelihood strategies. To address the impact of these and other stressors it is necessary to develop a deeper understanding of concepts such as ‘vulnerability’ and ‘food insecurity’. This is challenging as both concepts are used rather loosely in the food security literature, despite both having at least two dimensions. Vulnerability has an external and internal dimension, and food insecurity has a temporal and intensity dimension. However, assessments are often only concerned with one dimension at a time. An exploration of the two concepts suggests that in both cases the dimensions...

Food Insecurity and Vulnerability in Latin America and the Caribbean AgEcon
Gordillo, Gustavo; Winters, Paul C.; Corral, Leonardo.
This paper examines how Latin American and Caribbean (LAC) nations have proceeded in addressing the issues of food insecurity and vulnerability in response to the 1996 Rome Declaration on World Food Security. The data suggests that while the food insecurity situation has improved in LAC over the past few years, many nations are worse off in terms of food insecurity than they were at the beginning of the 1990s. Nations that reduced food insecurity tend to be those who have effectively reduced poverty and have increased social spending. While some regional initiatives have occurred to address regional food insecurity issues, additional national and international policy responses are required in the Latin American Region.

Food Insecurity in Households with Children: Prevalence, Severity, and Household Characteristics AgEcon
Nord, Mark.
Eighty-four percent of U.S. households with children were food secure throughout 2007, meaning that they had consistent access to adequate food for active, healthy lives for all household members. Nearly 16 percent of households with children were food insecure sometime during the year, including 8.3 percent in which children were food insecure and 0.8 percent in which one or more children experienced very low food security—the most severe food-insecure condition measured by the U.S. Department of Agriculture. Numerous studies suggest that children in food-insecure households have higher risks of health and development problems than children in otherwise similar food-secure households. This study found that about 85 percent of households with...

Food Spending Declined and Food Insecurity Increased for Middle-Income and Low-Income Households From 2000 to 2007 AgEcon
Nord, Mark.
From 2000 to 2007, median spending on food by U.S. households declined by 12 percent relative to the (rising) cost of USDA’s Thrifty Food Plan, and by 6 percent relative to the (rising) Consumer Price Index (CPI) for Food and Beverages. Over the same period, the national prevalence of very low food security increased by about one-third, from 3.1 percent of households in 2000 to 4.1 percent in 2007. The deterioration in food security was greatest in the second-lowest income quintile, in which the prevalence of very low food security increased by about half. These estimates, based on data from the nationally representative Current Population Survey Food Security Supplement, are corroborated by corresponding declines in food expenditures by middle- and...

HOUSEHOLD FOOD SECURITY IN THE UNITED STATES, 2001 AgEcon
Nord, Mark; Andrews, Margaret S.; Carlson, Steven.
Eighty-nine percent of American households were food secure throughout the entire year 2001. The rest were food insecure at least some time during the year, meaning they did not always have access to enough food for active, healthy lives for all household members because they lacked sufficient money or other resources for food. The prevalence of food insecurity rose from 10.1 percent in 1999 to 10.7 percent in 2001, and the prevalence of food insecurity with hunger rose from 3.0 percent to 3.3 percent during the same period. This report, based on data from the December 2001 food security survey, provides the most recent statistics on the food security of U.S. households, as well as on how much they spent for food and the extent to which food-insecure...
