A.Economic Rent Price paid for land or other resources that are completely fixed in supply (perfectly inelasticity supply) Changes in Demand Land Rent is a Surplus Payment due to same amount of land available in society –No ‘Incentive Function’ for rent because supply is fixed (next slide)
Economic Rent The Determination of Land Rent Acres of Land Land Rent (Dollars) L0L0 D1D1 D2D2 D3D3 D4D4 S R1R1 R2R2 R3R3 0 a b -- What is the value of land at each Demand curve? -- The supply of land is perfectly inelastic
B.Henry George Proposed a Single-Tax on land Progress and Poverty (1879) Economic rent could be heavily taxed without diminishing the available supply of land or economy as a whole Land performs no incentive function Critics cite many problems w/ this: -- Current Gov’t spending wouldn’t be covered by a single tax. The supply of land is perfectly inelastic
