Is -1.1 unitary elastic or less elastic
I presume that you’re talking about price elasticity of demand. (You should make that the title of the thread, by the way; “Economics” is pretty useless as a thread title.)
If so, then a good or service whose price elasticity of demand is −1.1 is price _ elastic _: the percentage decrease in demand is greater than the percentage increase in price.
Unitary elasticity is exactly what the name says: −1._ 0 _.
Thanks!
