A typical society strives to get the most it can from its scarce resources. At the same time, the society attempts to distribute the benefits of those resources to the members of the society in a fair manner. However, redistributing income from rich to poor reduces the reward for working hand. Therefore, society faces a tradeoff between

broader the definition of the market

Demand is said to be inelastic if

the quantity demanded changes only slightly when the price of the good changes.

Cross-price elasticity of demand measures how

the quantity demanded of one good changes in response to a change in the price of another good.

If something happens to alter the quantity supplied at any given price, then

the supply curve shifts

When a country has a comparative advantage in producing a certain good
