Khan Department of Economics University of Waterloo Fall 2011 Assignment 3 (Optional) Total Marks: 80 Marks Read each part of the question very carefully. Show all the steps of your calculations to get full marks, unless it is mentioned otherwise. 1.

Assume that the consumer has the preferences over the consumption good, c , and leisure, l , described by the following utility function. ( ) . ln ln , l c l c u + = She faces a market real wage rate, w , per hour. The consumer is assumed to have h hours of time available, which can be allocated between leisure time, l , and time spent working (or labour supply), denoted by s N . She receives π units of the consumption good as dividend income from the representative firm. Suppose that the government imposes a proportional income tax on the representative consumer. That is, for each w she earns on the market, she pays tw units of consumption good to the government where t is the income tax rate, and 0 < t < 1. There are no lump-sum taxes, or . 0 = T The representative firm is a perfectly competitive firm. Assume that the representative firm produces the consumption good only with labour as an input. It has the following technology to produce the consumption good: , d zN Y = where Y is the aggregate output of consumption goods produced by the firm, z is the exogenous total factor productivity and d N is the hours of labour employed by the firm. The firm faces a market real wage rate, w , per hour.
