Problems in Microeconomics

1. If the value of the coefficient of cross-elasticity of demand for commodity and the price of goods B is 0.7, and the value of the coefficient of elasticity of demand for commodity and income equal to 0.8, then a one percent increase in the price of the product B and one percent increase in income consumer demand:
a) increase;
b) decrease;
c) does not change;
d) nothing definite can be said.

2. Patties replace rolls in consumption and oil supplements. What happens in the relevant markets if the price drops buns?
a) the price of oil will fall and pies;
b) increase the price of pies, and the price of oil will go down;

3-6. In all these tasks, the following data:
A good number of price and revenue benefits Used Price
1000 5 200000 1000
1000 7 300000 1000
1000 7 200000 800
800 7 200000 1000

3. Based on the above information, we can conclude:
a) A and B are substitutes, while the A - normal good;
b) A and B are complementary benefits "But at the same time - a normal good;
c) A and B - substitutes, with good A is the lowest category;
d) A and B - are complementary goods "And at the same time is a boon lowest category.

4. Under these conditions, the absolute value of the price elastichnos¬ti demand for the product A is:
a) 0.67; b) 1.0; c) 1.5; g) 1.95.

5. In this case, the income elasticity of demand:
a) less than zero;
6) is zero;
c) greater than zero but less than unity;
d) greater than one.

6. Using these data, we can conclude that the cross-elasticity of demand (EAB) in the module is equal to:
a) 1.95; b) 1.5; c) 1.0; g) 0.67.

7. When the volume of manufacture 20 units AU are equal to 8. When the volume of the issue increased to 21 units, the speaker began to 9. In this case, MS 21st unit are:
a) 29;
6) 1;
c) 9;
d) the information is not enough.

9. Mr. Brown lives in his own house 200m2. He decided to resign from his job where he gets $ 2 thousand. Per month (for simplicity we assume that the entire amount he received at the end of the year), and to organize their own company, making outerwear. Brown bought the equipment and materials in the amount of $ 10 thousand. And $ 5 thousand. Respectively. For this he used their own savings ($ 5 thousand.), And a bank loan of $ 10 thousand. (For 1 year). In addition, he highlighted in his home studio rooms with a total area of \u200b\u200b100 m2. In the region, where Mr. Brown, the rent is $ 250 per 1 m per year. Interest on the loan is 20% per annum on deposits of citizens - 12% per year. Brown hired four tailors salary of each of which is equal to $ 1 thousand. Per month (for simplicity we assume that the entire amount they are paid at the end of the year). On average, each capable of tailors sew 25 per month. Average price per dress is $ 95.5. Determine the annual economic and accounting costs of Mr Brown. What are the economic and accounting profit Mr Brown?

10. We consider a competitive firm P = 6; TVC = 160; TFC = 120; AC = 7, AVC = min. Decide what should be done to the firm in the short term:
a) to increase the volume of production;
b) to reduce the volume of production;
c) leave unchanged the volume of production;
d) to close the plant.
