question
Studies have shown that as people's income is growing, the proportion of income that they spend on food is getting smaller. People in developing countries have low incomes and therefore spend a large part of it on food. For example, in Tanzania 62 percent of income is spent on food. On the other hand, in United States only 12 percent of income is spent on food. Based on this information, in which country we would expect elasticity of demand for food to be higher: in United States or in Tanzania?
answer
we would expect elasticity of demand for food to be higher in Tanzania, because people in Tanzania spend larger share of their income on food
