: Elasticity Analysis for Three Animal Protein Resources in Indonesia. This study aimed to analyze the behavior of household demand on three sources of animal protein (fish, beef, and chicken) were associated with different household characteristics and analyze the response of households in Indonesia to changes in price and income on the consumption of fish, beef, and chicken. Almost Ideal Demand System (AIDS) was adopted in this study, using data from the Indonesia Family Life Survey wave 4 (IFLS 4). Total number of the household analyzed in this study amounted to 839 households. The results showed that partially price of fish, beef prices, household expenditure, geographic region, and number of family members affect the share of expenditure fisheries products, chicken, and beef. The results implied that Price elasticity of demand for demand for fish, beef, and chicken were categorized as inelastic. While the income elasticity for beef and chicken were elastic, furthermore income elasticity for fish was inelastic.
