1. A consumer has preference over two goods $x_1$ and $x_2$ represented by $u(x_1, x_2) = \ln x_1 + x_2$ Let the price of $x_1$ b p, the price of $x_2$ be 1, and let the income be $m > 1$ (a) Derive the Marshallian demands function for $x_1$ and $x_2$ (b) Derive the expenditure function. (c) Use the slutsky equaiton to decompose the effect of on own price change on the demand for $x_1$ into income and substitution effects. Interpret your results. (d) Suppose that the price of $x_1$ raises from $p^0 to p^1 > p^0$. Find CV, EV and change in the consumer surplus connected with the price increases.
