1. Your nominal income is CZK 10,000. The price of a meal is CZK 100. Your real
income in terms of meals is 100 meals: You can afford to buy 100 meals for your
income. What happens to your real income in terms of meals if the nominal price

2. Two primeval men, Hunter and Gatherer, meet in the forest. Hunter carries 20 kilos
of meat and Gatherer carries 20 kilos fruits. Gatherer offers 2 kilos of his fruits to
Hunter in exchange for 1 kilo of meat. If Hunter killed Gatherer, he would gain all
his 20 kilos of fruits, which would increase his utility by 200 degrees of utility at no
cost. If he accepted the deal, he would gain 2 kilos of fruits which would increase
his utility by 60 degrees of utility and he would lose 1 kilo of meat which would
decrease his utility by 20 degrees. If Gatherer gained 1 kilo of meat he would
increase his utility by 50 degrees and if he gave up 2 kilos of fruits he would
decrease his utility by 10 degrees. How many times should they meet repeatedly
for the same transaction so that trade pays for Hunter in comparison with robbery?
Answer: 5
