Effect on market

  • Initially the market was at an equilibrium level of output with price P* and quantity Q*. After the subsidy is granted, the supply has increased, shifting the supply curve from S1 to S2 due to the decrease in cost of production. This therefore forms a new equilibrium output, with a lower price for consumers Pc, a higher receiving price for producers Pp, and greater quantity Qsb. The vertical difference between S1 & S2 represents the per unit subsidy
