With more police and security workers wearing bulletproof vests, the demand for vests will increase. At the same time, the fall in price of ceramics used to produce vests will lower the cost of production, which will increase the supply of vests. Hence, both the demand and supply will increase, resulting in an increase in equilibrium quantity produced. However, the effect on equilibrium price is ambiguous because the increase in demand and supply may offset each other or not depending on the magnitude of change in each.
