Презентация на тему The national economy as a system

the problems of economic growth and employment, opportunities and

work of the economic mechanism of the functions of the state and economic policy called macroeconomics.
The objective is to analyze the interaction of macro economic operators and individual markets.
  Under the national economy is considered to be the country's economy. This is a collection of all sectors and regions, connected in a single organism multilateral economic ties.

state is reflected in the national accounts

National Accounts -

a collection of various macroeconomic indicators.

well-being of society. The primary measure in the preparation

of the SNA is the gross national product, or - briefly - GNP.
Gross national product (GNP) - is the total market value of the total final output of goods and services in the economy for the year.
Gross domestic product (GDP) - is monetary value of all final goods produced and services in the economy for the year in that country.
Net National Product (NNP) is the gross national product, net of depreciation.
GDP = NNP – D (net of depreciation)

annual cost, which has added production in a given

year to the welfare of society. With his calculation does not include the amount of depreciation, indirect taxes and government subsidies. LP - a "Wages income" society (wages, income, profits).
NI = NNP – Te (indirect taxes)
Personal income (PI) is the total income received by the owners of economic resources.
PI = NI - contributions to system of social insurance - corporation profit taxes - retained earnings of corporation + transfer payments
Disposable income (DI) - the income, which is in the personal possession. It is smaller than the personal income tax on the value of the individual, who must pay the owners of economic resources in the form of the (primarily income) taxes.
Yd = PI – individual taxes

+ I + G + Xn ,
where:
C -

personal consumption expenditures of households on durable consumer goods, goods for current consumption, and consumer spending on services.
I – gross private domestic investment, or "investment spending." They include three components: 1) the purchase of entrepreneurs machinery, equipment and tools, 2) all construction (commercial and residential construction), 3) investments in stocks.
G - government procurement, which include public consumption and public investment.
X – net exports. It represents the difference between income from exports and expenditure on imports of the country and meets the trade balance.

CONSIDERED AS THE SUM OF REVENUE OF OWNERS OF

RESOURCES, I.E. AS THE SUM OF FACTOR INCOME GROSS DOMESTIC PRODUCT = (C+S) + I + R + Π + D

the calculation of GNP must sum of value added

by all sectors and industries in the economy. An objective analysis of the economy is possible only with a stable (or comparable) price level. Analysis of the price level is necessary in order to:
- To know whether there have inflation or deflation,
- Reduced to a single base heterogeneous components of total production.

detailed version of the circular flow, we will illustrade

the model of the firm.
A firm in our model is a unit which adds value to products. These products may be raw material, semi-manufactured goods, final goods and services. By adding value, we mean that the firm acquires the good, adds value to it and then sells it. A supermarket adds value to a final good by making it more available to consumers and a bakery adds value to flour when it bakes bread.
From the diagram we see that the value added in a firm must be equal to the compensation to the factors of production. This must be the case since the net flow of money for a firm must be zero (remember that profits become return to capital – a compensation to the owners of the firm).

into three categories: FR consists of all firms that

acquire raw material (iron ore, farm products and so on), FH all those that produce semi-manufactured goods (steel, pulp and so on) and FF all firms producing finished goods (software, cars and so on). We use the symbol Y for GDP. All of Y will go to the firms in the FF box. However, if we sum the value added from all firms, we will get exactly Y.
If YR is the total value of all goods going from FR to FH, then the total value added from all firms in the FR box is equal to YR (they do not purchase any goods to which they add value)
In the same way, if the total value of all goods going from FH to FF is given by YH, then the total value added from all firms in the FH box is YH – YR.
In the same way, the total value added for all firms in the FF box will be equal to Y – YH. If we sum all the value added from all firms, we get
YR +(YH – YR) + (Y – YH) = Y
The total return to the factor market = Sum of all value added = GDP
