Answer:
In this case,the increased demand or popularity of "Economics Professor" is attributable to a non-price factor in the market which would lead to a higher overall demand and both equilibrium price and quantity.
Step-by-step explanation:
A sudden increase in demand or popularity of Economics professors imply that the overall market demand for the professors would increase reflected by a rightward shift of the demand curve of the professors in the demand-supply diagram.This would essentially lead to an increase in the equilibrium price level in the market initially,considering all other factors in the market constant.Now,due to the increase in the market price,the quantity supplied of Economics professors would increase in the market and would eventually lead to a higher equilibrium quantity in the market.In the demand-supply diagram,this scenario is reflected by the intersection of the new demand curve and the supply curve.Hence,due to increased demand or popularity of Economics professors,both equilibrium price and quantity will increase in the market.
