Question: Beef and leather belts are complements in PRODUCTION (in other words, when the output of beef increases, the output of leather belts increases as well, and vice versa). Assume that the markets for beef and leather belts are initially in equilibrium. Suppose that concern about health and diet shifts the demand curve for beef leftward. Use supply and demand analysis to determine what will happen in the market for leather belts. In other words, determine

(a) if there will be any shift in the demand for leather belts;

(b) if there will be any shift in the supply of leather belts;

(c) if the equilibrium price of leather belts will increase, decrease, or stay the same;

(d) if the equilibrium quantity of leather belts will increase, decrease, or stay the same.
