| Sales of organic milk in mainstream supermarkets have grown over the last 8 years, reaching $75.7 million in 1999, as more organic milk processors enter the market and more mainstream supermarkets sell organic products. National-level scanner data for mainstream supermarkets are employed to assess market shares and price premiums, as well as to estimate key demand elasticities. Container size is important in analyzing market shares for organics. Half-gallon containers are the principle organic market with volume shares ranging from 1.6% to 2.8% in 1999. Market shares for quarts and gallons of organic milk are considerably below 0.5%. Price premiums for organic milk averaged 60% of branded prices and 75% of private-label prices during the study period... |

| The paper focuses on separability in the almost ideal demand system (AIDS) in time series analysis. The AIDS approximation based on Stone's price index is specified in terms of the Rotterdam model and block additivity is imposed for illustrative purposes. A generalization to other types of separability is then considered. The model can be viewed as an extension to Theil et al.'s Working-PI time series model. In both the Theil et al. model and the AIDS model examined here, the marginal propensity to spend on a good is allowed to depend on the good's budget share. In the model in this paper, the Slutsky coefficients are further allowed to depend on the budget shares. The model provides a consistent way to analyze subgroup demand relationships. |

| Meat consumption and socio-demographic data from the 1990, 1993 and 1996 SUSENAS Household Food Expenditure and Consumption Surveys were employed to estimate the demand for meats in Indonesia. The focus was on the Provinces of DKI Jakarta and West Java where about one-fourth of the Indonesian population reside. Statistical and econometric procedures were used to aggregate the 16 meat types recorded in the SUSENAS into four Meat Groups. They were then used to estimate the Linear Approximation of the Almost Ideal Demand System (LA/AIDS) model, taking into account zero observations and the restrictions on budget shares. The demand for Meat Group 1 (with the dominant meat, beef) is income-inelastic, whereas for Meat Group 2 (with the dominant meat,... |
