| Food consumption behaviors in food secure and food insecure households are compared. A two-stage budgeting and a double-hurdle model are used in the estimation. The results of the paper show that both food away from home and food at home are normal goods for both food secure and food insecure households. However, the effects of family structure on food consumption differ for the two household types. For food secure households, having one more child or one more working family member results in a larger marginal increase in food consumption than that for food insecure households. In addition, households with married heads of household are more likely to eat out in food secure households but less likely to eat out in food insecure households compared to... |

| Significant economic changes have occurred in Lithuania since 1992. Major market reforms were introduced through phased liberalization of producer and consumer prices. Panel data from a Lithuanian Household Budget Survey conducted during 1992-94 were used to estimate demand parameters for aggregated commodity groups. The evidence from the household survey shows the relative stability of demand parameters. Estimated price and expenditure elasticities are consistent with levels of low income countries. Households have been relatively responsive to changes in prices and total expenditure in their purchases during the period of transition. |

| An important dimension of product differentiation and segregation for specialty crops is the added handling and transaction costs incurred. Some forms of business organization may realize lower costs of providing such services, and if specialty crop production is growing relative to commodity production, these two factors may have implications for industry structure. We use data from an Iowa grain handling survey to test hypotheses developed in the non-empirical transaction-costs literature with respect to organizational and financial governance of cooperatives and private and corporate firms. Preliminary results are discussed with respect to business organizations, added costs, investments, crops, and contracting. |

| In 1993, Iowa obtained a waiver to enact many of the key provisions of Temporary Assistance for Needy Families (TANF) in its welfare assistance and initiated the Iowa Family Investment Program (FIP). We use Iowa state administrative data for the period 1993-95 and study why some low-income households successfully leave public assistance while others who leave later return. We focus on those who were active in FIP at the time of the program reforms. The research explores the role of employment, earnings, and other support such as the Food Stamp Program (FSP) and child support for recipients who leave FIP. Geographic (metro and nonmetro) differences are of specific interest. Reasons for recidivism are examined over time, with specific attention to local... |

| Food assistance programs play an important role in meeting the basic needs of low income households. This paper examines the interaction among food stamps, labor force participation and food insecurity status of low-income households under different program design and economic conditions. A simultaneous equation model with three probit equations links the program, work force participation and outcome. Results based on the Survey of Program Dynamics data suggest that Food Stamp Program participation is more responsive to changes in the program benefits than to changes in unemployment rate or nonlabor income; food insecurity status is more responsive to changes in the food program benefit or unemployment rate, than to nonlabor income. |

| 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... |

| A representative sample of 49 state and collective farms in Ukraine provides data in physical units on livestock and crop production and input use for 1989-92. The changes in production efficiency for beef, pork, dairy, winter wheat, grain, and potato production, investigated using stochastic frontier methods, show declining technical efficiency in livestock production and especially low marginal contribution of labor inputs. The number of workers, size of farm, and distance from nearest city are related to efficiency in agricultural production. |

| WIC, the Special Supplemental Nutrition Program for Women, Infants, and Children, is a widely studied public food assistance program that aims to provide foods, nutrition education and other services to at-risk, low-income children and pregnant, breastfeeding and postpartum women. From a policy perspective, it is of interest to assess the efficacy of the WIC program - how much, if at all, does the program improve the nutritional outcomes of WIC families? In this paper we address two important issues related to the WIC program that have not been extensively addressed in the past. First, although the WIC program is primarily devised with the intent of improving the nutrition of "target" children and mothers, it is possible that WIC may also change the... |

| In response to the recent outbreaks of food-borne illness, the Good Agricultural Practices program has been widely adopted to ensure consistency of food safety. This paper presents a theoretical framework to analyze the performance of the program with respect to output quality based on the assumption of predetermined productive capacity (farm size), heterogeneous farms and exogenous detection. Our main results are: (i) farms respond to the monitoring and enforcement not only by reducing fraudulent output, but also by increasing truly high-safety output until the perfect compliance level is achieved. (ii) the monitoring agency takes farm strategies as given and its optimal inspection policies are: If the monitoring budget is not enough to cover the... |

| The most widely used measure of milk hygiene is Somatic Cell Count (SCC), where low SCC values indicate more wholesome milk. Dirt, often associated with grazing, carry bacteria and these bacteria can cause mastitis. Milk from cows with mastitis generally has higher SCC levels and cows with mastitis are most readily treated with antibiotics. Milk with high SCC is penalized by distributers as it is difficult to process and is not considered as wholesome in fluid markets. Grazing cows is common for many organic farmers. However, regulators prohibit antibiotic use under organic production. Intensive management protocols, maintaining equipment, and closely managing the herd’s environment offer substitutes for antibiotics use. Organic milk carries with it a... |

| The double-hurdle and infrequency-of-purchase models are applied to pork and cheese consumption using the 1987-88 Nationwide Food Consumption Survey data. The models are generalized with the inverse hyperbolic sine transformation in the dependent variable, and this transformation results in a more flexible parameterization and error distribution than the untransformed models. Nonnested LR tests suggest that the IHS double-hurdle model provides better characterization of the data-generating process in household pork consumption than the IHS infrequency-of-purchase model but the elasticities derived from these models are similar. For household cheese consumption, the two models fit the data equally well. The IHS double-hurdle model and the IHS... |

| The macroeconomic crisis in Indonesia in the late 1990s reduced real per capita income by 74 percent and increased prices of some food groups by 92-445 percent. Adjustments in the consumption decisions of households during this period was analyzed using SUSENAS data. The data showed a very strong pattern of adjustment in the consumption decisions of households. That is, households substituted away from more expensive food groups to cheaper alternatives. Of the nine food groups examined, per capita consumption declined in seven food groups with largest declines in eggs-milk (38%), fish (20%), and meats (13%). In contrast, consumption of the cheapest food group - tubers, increased by 22 percent. Also, households substituted away from the expensive... |
