ECON-101 Chapter Notes - Chapter 8-14: Pigovian Tax, Tax Rate, Root Mean Square
Document Summary
C+e = deadweight loss (dwl) of the tax, due to tax, units between qt and qe are not sold. Value of these units to buyers is greater than cost of producing them, so tax prevents some mutually bene cial trades. Size of dwl; price elasticities of supply and demand. When supply is inelastic its harder for rms to leave the market so tax only reduces q and dwl is small. When supply is more elastic, its easier for rms to leave market when tax reduces ps. The greater q falls below the surplus maximizing quantity, the greater the dwl. When demand is inelastic, its harder for consumers to leave the market when tax raises pb, so tax only reduces q and dwl is small. When demand is elastic its easier for consumers to leave the market when the tax increases. Pb, the more q falls below the surplus, maximizing quantity, and the greater the dwl.
