Money & WorkMental model
Who writes the cheque says nothing about who bears the tax.
Tax incidence separates the legal payer from the actual bearer. Whether a tax is levied on buyers or sellers does not change the outcome – elasticities decide. Whoever can least easily change their behaviour carries the larger share of the burden.
Useful: With any new levy, ask who can adjust their behaviour: the immobile side ends up paying.
