The government will increase MPC to match MSC.
Effects of indirect taxes on consumer and producer surplus
Movement on curve vs. shift of curve (demand/supply same concept)
Consumer/producer surplus in competitive market
How does a change in demand single price change?
Elastic PED curve
Unit elasticity (PED=1)
Varying PED along a demand curve
As you get towards the right of the curve for example, the change in percentage demand is much lower than the percentage change in price. (E.g.) Price goes from 0.1-0.2=50% increase. Qd goes from 50-49 = approx.. 0.02 decrease. This gives inelastic value like on curve.
How government revenue is effect with different PED
XED is positive when products are substitutes.
Complimentary products XED
XED is negative when products of complimentary.
YED of inferior goods, inelastic normal goods and elastic normal goods

Welfare loss is also measured by the triangle created by Qfm (free market)
Tax required to make MSC and MPC is the distance between MSC and MPC.
Realistically, tax will not completely cover the tax gap.
