The supply of engagement rings will increase. So long as the actual market price exceeds the equilibrium market price, there will be 2-23 a. downward pressure on the price. b. upward pressure on the price. c. excess demand. d. a shortage. In which of the following cases will the effect on equilibrium output be indeterminate (i.e., 2-24 depend on the magnitudes of the shifts in supply and demand)? a. Demand increases and supply increases b. Demand decreases and supply decreases c. Demand decreases and supply increases d. Demand remains constant and supply increases Increases in the wage rates of coal miners and decreases in the price of natural gas would cause 2-25 the price of coal to a. rise, fall, or remain unchanged depending on the magnitude of the changes, but the equilibrium quantity of coal fall. b. rise, fall, or remain unchanged depending on the magnitude of the changes, but the equilibrium quantity of coal would increase. c. rise, but the equilibrium quantity of coal would rise or fall depending on the magnitude of the changes. d. rise, but the equilibrium quantity of coal would fall. e. fall, but the equilibrium quantity of coal would rise or fall depending on the magnitude of the changes.
