Final answer:
The coefficients of income elasticity of demand provide insights into the economy.
Step-by-step explanation:
The statement is true. The coefficients of income elasticity of demand provide insights into the economy. Income elasticity of demand measures the responsiveness of the quantity demanded of a good to changes in income.
A positive income elasticity indicates a normal good, where a rise in income leads to an increase in demand. On the other hand, a negative income elasticity indicates an inferior good, where a rise in income leads to a decrease in demand.
