(pi – MC)/pi ej
________ = __
(pj – MC)/pj ei
Pi = price of the i-th good; MC = marginal good in the markets of the i-th good; ei = Price elasticity of demand for the i-th good.
Thus, for two goods i and j selected from the quantity of all existing goods, the tax rates levied on consumption of i and j will be in inverse proportion to the price elasticities of demand. With relatively low price elasticity, relatively high tax revenues can be achieved without causing major substitution effects (and thus welfare losses). (RamseyVsEdgeworth, see Taxation/Edgeworth, Taxation/Ramsey.
The rule therefore says something about the optimal ratio of tax rates on consumer goods to each other. However, this does not say anything about the amount of the tax. See also economic theories on taxation

VsRamsey: Problem: if goods with very low price elasticity of demand are, for example, staple foods or drinking water, the Ramsey Rule can quickly have undesirable, strongly regressive distribution effects. The tax system would place a disproportionate burden on relatively poor households.
Solution/DiamondVsRamsey/MirrleesVsRamsey: those goods that are heavily consumed by individuals whose welfare still has a strongly positive marginal effect on social welfare should be taxed less. (1)(2)
This integrates the weighing of pure efficiency goals and ideas of distributive justice.
