Talk:Marginal revenue

what is the effect of mr. of a firm to that of industry Economics is Hard

Economics is easy. read your textbook.

what does 'd' stand for?
 * It stands for "derivative"; think of it as difference for a small change (strictly speaking, infinitesimal change). --Sabik 03:20, 28 July 2007 (UTC)

i dont agree with the assertion "When marginal revenue is equal to zero, price elasticity of demand is equal to 1." because if revenue equals price times quantity sold, and price elasticity of demand is equal to the percentage change in quantity demanded divided by the percentage change in price, then for price elasticity to be plus one, a positive increase in price would increase demand, and this implies an increase in revenue. —Preceding unsigned comment added by 138.38.217.40 (talk) 16:21, 13 October 2007 (UTC)

the coefficients of price elasticities of demand are always negative - economists conventionally use absolute values when discussing price elasticities of demand (PED)- at the point of unitary elasiticity the coefficient is negative 1 - abosulte value 1. A decrease in the price would move you into the inelastic range of the demand curve - for price decrease in inelastic range total revenue falls - if you were to raise prices thus moving into the elastic range total revenue would also fall. thus at unitary elasticity total revenue is at its maximum value which implies that MR = zero.--Jgard5000 (talk) 11:07, 27 September 2009 (UTC)jgard5000

Marginal revenue is the amount received from selling one extra unit of output

formula MR= TRn - TRn-1 units

Graph doesn’t display
The graph in the lead doesn’t show the curves on my screen. Since this is the first time I’ve encountered this, I don’t think the problem is due to my machine or my display capabilities. Could someone look into this and make the graph universally readable? Thanks. Loraof (talk) 18:40, 28 January 2019 (UTC)
