# Why don't suppliers increase price after a positive demand shock?

Forgive me, I am new to economics. Suppose there's a demand shock in the pork market and D1 shifts to D2. Why not keep quantity supplied fixed at 220 and then raise prices to $3.70, instead of moving from e1 to e2? It seems to me that suppliers stand to make higher revenues by only raising the price, because 3.70 * 220 > 3.50 * 228. • At$3.70, you have excess supply. Jul 13 '20 at 5:26
