THEORIES OF TAX SHIFTING
Theories of tax shifting
1. The Diffusion Theory
This theory states that eventually, it becomes impossible to trace the final incidence of any tax and that in
reality, all taxes get diffused in the economic system.
It is based on the assumption that the market is sufficiently competitive and that the factors of production
can move from one employment to the other quickly, easily and without significant costs.
Because of the constant interactions by sales/purchases transactions, a tax imposed at one place could shift
to all sectors of the economy thus becoming untraceable.
2. Demand and supply Theory
A tax may be shifted through sale/purchase transactions depending on the elasticity of demand and supply.
Shifting is through a revision of prices.
If the demand is inelastic, tax can easily be shifted by the seller to the buyer.
Where demand is elastic, the burden of tax will mainly be borne by the seller
