1. Gertrude had a weekly income of $9. At that time, a bulla sold for $1 and a drink for $1.50. a) What is Gertrude's real income in terms of bullas? b) What is her real income in terms of drinks? c) What is the relative price of a drink (in terms of bullas)? d) Sketch Gertrude's budget constraint (placing drinks on the vertical axis). e) Suppose she chooses to consume 3 bullas and 4 drinks per week. Is she satisfying her budget constraint? 1) Sketch the budget line if the price of bullas rises to $2 and all other values remain unchanged. g) Sketch the budget line if the price of drinks rises to $3 and all other values remain at their original levels. h) Sketch the budget line if Gertrude gets a raise to earn $18 a week and prices remain at their original levels. 1) Supposes all changes take place together: the price of bullas rises to $2, the price of drinks rises to $3, and Gertrude gets a raise to earn $18 a week. How does the new budget line compare to the original one? 2. Sketch the budget constraint for a prisoner at the general penitentiary who has been smuggled a pack of cigarettes (with 20 cigarettes) if one cigarette can be traded for two cell-phone calls. 3. Consider the consumption bundles indicated on the diagram. For each of the following pairs, determine if one is preferred to the other (i) with certainty, (ii) likely but not with certainty, or (iii) can't say at all. Explain your reasoning. [Hint sketch some possible indifference curves] a) D and E. b) C and D. c) A and C. d) B and C. e) C and E
