QB = 3 40 — 6Рв + 0.9Y — 2PA + 1.4Pc + 13QUB Where QB is the demand for good B; Pg is its price; Y is consumer income; PĄ and Pc are the prices of other goods and QUB is the quality of good B. Assume that Pg = 3; Y = 1000; PA = 5; Pc = 5; QUB = 6. %3D Which of the following correctly provides the relevant elasticities of demand and the correct explanation? YED is income elasticity of demand; CEDBC is cross price elasticity of demand between goods B and C and QUEDB is the quality elasticity of demand for good B. (а) YED — and C are complements; there is a positive impact on demand for good B from quality improvements. (b) YED = 0.9; CEDbc C are substitutes; there is a positive impact on demand for good B from quality 8.49; CEDBC = 0.066; QUEDB = 0.736. Good B is a normal good; goods B 0.094; QuEDB = 13. Good B is a normal good; goods B and improvements. (c) YED = 8.49; CEDBC = 0.066; QUEDB and C are substitutes; there is a positive impact on demand for good B from quality improvements. (d) YED = C are substitutes; there is a positive impact on demand for good B from quality 0.736. Good B is a normal good; goods B 0.9; CEDBC 0.094; QUEDB = 13. Good B is a normal good; goods B and improvements.
