Document Summary

Q (cid:32) dp dq p p1 p2 (cid:39)p (cid:39)q. The law of demand may be summarized as the following function where demand is q. (pfq (cid:32) Q: the market demand curve for a product is derived from the horizontal summation of individual direct demand functions, for example, there are 3 individual direct demand functions in the market: Individual 3: q3 = f(p: direct market demand function, q: q = q1+ q2+ q3. Pf = future expected price; a = advertising; and pop = population) Elasticity: elasticity = the percentage change in one variable (a) resulting from one percentage change in another variable (cid:75) (cid:32) A we will discuss the following four elasticities: (cid:75) Elasticity: own-price elasticity of demand ((cid:75)x) (arc and point elasticities, cross-price elasticity of demand ((cid:75)xy, income elasticity of demand ((cid:75)i, advertising elasticity of demand ((cid:75)a) X we have a direct demand function, you can us.
