| 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. |

| 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... |

| The 1991 Latvia household budget survey provided data for establishing basic information about food consumption levels and patterns in Latvia during the first year of major economic reforms. This study evaluates one aspect of economic decision making of households: how income is allocated for consumption of various broad categories of food items. The analysis uses the 1991 data to examine the importance of income and household composition on food expenditures. Estimated income elasticities for various food commodities suggest the magnitude of changes in real household income that have occurred in Latvia. With relativity low income elasticities (estimated from the 1991 data), declines in household income would not be met by significant reductions in food... |

| When using household-level data in examining consumer's demand it is common to find that consumers purchase only a subset of the available goods, setting the demand for the remaining goods to zero. Ignoring such censoring of the dependent variables in the estimation can lead to biased parameter estimates. In this paper we investigate the household's demand for six types of whole grain and non-whole grain breakfast cereals and products using a censored Almost Ideal Demand System (AIDS) and estimate the parameters of the demand system via Bayesian methods. Using 2006 ACNielsen Homescan data we find that demand for whole grain and non-whole grain ready-to-eat cereals is less responsive to changes in prices; demand for whole-grain bars and non-whole grain hot... |

| Hypothetical bias is a persistent problem in stated preference studies. We propose and test a method for reducing hypothetical bias based on the cognitive dissonance literature in social psychology. A central element of this literature is that people prefer not to take inconsistent stands and will change their attitudes and behavior to make them consistent. We find that participants in a stated preference willingness-to-pay study, when told that a nonhypothetical study of similar goods would follow, state significantly lower willingness to pay than participants not so informed. In other words, participants adjust their stated willingness to pay to avoid cognitive dissonance from taking inconsistent stands on their willingness to pay for the good being... |
