The demand for the set of goods X (1,2,3) and the income and of the consumers i and j are represented in the following set of matrx and vectors:
[[i],[j]][[4,7,9],[2,5,10]][[mi],[mj]]
with the prices of all goods equal to 1. If the utility function of the consumer i is and the utility function of the consumer j is 1.1 what is the individual demand of consumer i and j if we apply a specific commodty tax t=1 on good ? 1.2 what is the functional form of the aggregate demand for good ? 1.3 calculate the deadweight loss from a tax t=1 on good x3?
