Consider an individual with preferences defined over two goods, X1 and X2. This individual has preferences that can be represented by the following utility function: u(X1, X2) = X1 + X 0.5 2 Let P1 = 4 and P2 = 2. In addition, suppose this individual has an income of $120.

(a) Write down the expression for this consumer’s marginal rate of substitution of X1 for X2 (MRS12). Identify the distinguishing feature of this particular MRS12.

(b) Calculate the optimal basket of X1 and X2 and fully illustrate this optimal choice in a diagram with X1 on the horizontal axis.

(c) Suppose the government introduces a $2 tax on the consumption of each unit of X2 but X1 remains tax-free. Calculate the new optimal basket of X1 and X2. Illustrate this new optimal choice in your diagram above. (d) [7 marks] Calculate the compensating variation needed to return this consumer to her original utility level.

1/Laura's preferences over commodities x1 and x2 can be represented by U(x1,x2)=min{3x1, x2}. She maximizes her utility subject to her budget constraint. Suppose there is an increase in p1.   There is an income effect but not a substitution effect of this price change. There are both income and substitution effects of this price change. There is a substitution effect but not an income effect of this price change. It is unclear whether the consumer will buy more or less x1...

Two goods are given, where x1 and x2 are the number of units of these goods. The preference structure of a consumer is given by the following (ordinal) utility function: u (x1, x2) = x1 * x2 The indifference curves show a strictly convex course to the origin. The prices of the goods are given by p1 and p2. The consumer wants to achieve the level of utility ū with minimal expenditure. Determine the Hick’s demand function Please specify the...
