Topic 1. Fundamentals macro approach to the assessment of economic objects and processes
The inflation rate in the 15 EU countries in 1995 amounted to (%):
3.4 4.9 4.2 3.8 1.2 2.2 2.2 4.9 5.6 3.7 4.6 1.4 1.6 1.7 2.6.
By the condition of the Maastricht Treaty the standard deviation of inflation from the average of 15 countries should not exceed 3. Follow whether this requirement?
Theme 2. National economy as an economic system
Problem №15
National production comprises two products: X (consumer goods) and Y (means of production). This year produced 500 units of X (the price per unit - 2 den. U) and have 20 units (price per unit - 10 den. U). By the end of this year, five of used machines (product Y) must be replaced with new ones.
Estimate:
1. The value of GNP.
2. The value of NNP.
3. The volume of consumption.
4. Gross investment.
5. The amount of net investment.
The terms appearing in the problem:
Gross national product (GNP) - is the total value of all final goods and services produced in a country within a year.
Gross private domestic investment - is the cost of the newly produced means of production (machinery, tools, equipment, buildings), intended for the production process and the replenishment of inventories.
Net investment - is gross investment minus depreciation.
Net National Product (NNP) - a gross national product, less the amount of depreciation.
Subject 3. Measurement of national output, national income and price levels

According to the following input data to calculate:
1) GNP flow of income;
2) GNP downstream costs;

The terms appearing in the problem:
Depreciation - is the annual contributions equal to the value of consumption for the period of capital.
Gross national product (GNP) - is the total value of all final goods and services produced in a country within a year.
Gross private domestic investment - is the cost of the newly produced means of production (machinery, tools, equipment, buildings), intended for the production process and the replenishment of inventories.
The remuneration for the labor of employees - it is wages, salaries and allowances to them.
Government procurement of goods and services - all government spending on final goods and services (they do not include transfer payments).
Government transfers - the state is paying separate individuals (or families) received free of charge.
Indirect taxes - a tax that the company includes in costs of production; they are passed on to consumers by raising the prices of goods and services.
Personal consumption expenditures - household spending is directed to the purchase of commodities and services.
Personal income - is income coming to households before taxes.
The method of calculating GNP flow of income - it is the sum of all revenues derived from the production of the total output of the year.
The method of calculating GNP downstream costs - is the sum of all costs for the final product.
The national income - is a net national product minus indirect taxes.
Locate

Production functions are of the form: Y = (4 × K2 + 3 × L2) 0,5; Y = 4 × K + 3 × L; Y = 2 × K0,4 × L0,6; Y = 1/3 × (K × L2) 0,5.
What is the efficiency of scale (increasing constant decreasing) they describe?
