2. Elisa's preferences over leisure (h) and consumption (c) are given by the utility function U(h, c) = c + 10(N+1)ln(h). Elisa has 16 hours a day she can devote either to leisure or to work at the current market wage w. She also enjoys a daily stipend of 10(N+1) paid by her parents. a) Find the expression for Elisa's budget constraint and represent it graphically with consumption on the vertical axis. Find her demand for consumption and her labour supply as a function of the price of consumption and the wage. b) Assume w = 10. Find the substitution and income effect in Elisa's demand for leisure if the government imposes a 20% tax on labour income. Represent the situation graphically. c) Find the compensating equivalent corresponding to the introduction of the tax
