(Equilibrium) Consider the following graph in which demand and supply are initially D and S, respectively. What are the equilibrium price and quantity? If demand increases to D', what are the new equilibrium price and quantity? What happens if the government does not allow the price to change when demand increases?
First question: solution to a question in which we are given information on the hours of labor required to produce wheat and cloth in the UK and the US. We determine opportunity cost, absolute and comparative advantage, and who should specialize.
Second question: provides the shape of the PPF for a country that can produce Cars and Washing Machines and determines the opportunity costs at different units of production.
Solution also includes a number of multiple choice questions about the demand and suppply of ice cream.
