It appears some students in this website are confused about elasticity of demand and the slope of the demand curve when they are trying to figure out why rectangular hyperbola comes up in case of unitary demand curve. First, they don't know that RH can be depicted in a positive quadrant of price,quantity plane. Secondly, they make the mistake that the slope of RH is constant at -1. Two points could help them: first, e=1 at each and every point of the RH, because the tangent at any point shows lower segment=upper segment (another geometric definition of e); yet slopes at different points,dQ/dP, are different; second, e is not slope but [(Slope)(P/Q)]in absolute terms. Caveat: only if we measure (log P) along the horizontal axis and (log Q) up the vertical axis, can we then say slope equals elasticity --in which case RH on P,Q plane is transformed into a straight-line demand curve [with slope= -tan 45 deg] on (log Q),(logP) plane, and e= -d(log Q)/d(log P). [By the way, logs are not used in college textbooks --although that is helpful in econometric estimation of elasticity viewed as an exponent of P, when demand equation is transformed into log-linear form.] I have not found the geometrical explanation I have given in any textbook followed in undergraduate and college classes in Canada (including the book followed in a university where I taught for a short time and in the book followed in George Brown College, Toronto, where I teach.

##### Experience in the area

#### 2016-11-22 communist economy - followup:

Hi Amtry,    Thank you for you new type of question which is something very uncommon, but indeed this is a new though towards a new direction. The questions are: (a) Is it practicable? (b) Will it work?

#### 2016-11-13 communist economy:

Hi Amtry,    To be frank, nobody exactly knows how a communist economy works. Obviously, true communism does not exist and never has. All we know is about different variants of communist economies –Russian

Hi Prashant,    I am sorry that I was a trifle busy and could not attend to your query earlier.    Actually, the bank normally does not object to black signature, though blue signature would be to your
