However the main feature of Keynesian model that real and monetary sector of economy are interconnected. The specified interrelation is caused Keynesian treatment of monetary demand, according to money is wealth and has independent value, and is expressed via the transmission mechanism of a rate of percent.
Expression (represents a condition dynamic a : growth will be equilibrium if rate of a gain of investments is equal to work of limit productivity of the capital and tendency to saving.
The offer of work at a rate of a salary of W0 makes N2, that is in labor market unemployment in a size (N2 – N takes place. But as employment at a rate of N0 from the offer of work will be provided and at lower rate of a salary, than W0, that is an inequality condition (it is carried out, in labor market balance is observed.
The theoretical design of behavior of house farms in the consumer market offered by Keynes had huge impact on development of macroeconomic researches, on it is based both the theory of the animator, and Keynesian interactions of the markets.
In case of decrease in a rate of a salary below W0 businessmen all the same will not be able to employ workers more, than N0 as to an the offer of the benefits will exceed effective demand, and in the market of the benefits is formed surplus.
In our example it is a rate of a nominal salary of W Thus, growth of a nominal salary of W0 specifies to reduction of demand for work above, however to raise demand for work only growth of effective demand for the benefits.
If the guaranteed growth rate is higher natural, the increase in population is insufficient to provide dynamic balance. In this case the actual growth rate will be lower guaranteed that will lead to decrease in outputs.
Thus the rate of a real salary presented in the second quadrant can change as a result of fluctuations in price level: the increase in prices causes shift of the schedule up and reflects an of a real salary, reduction of prices — respectively, down and reflects growth of a real salary.
Let's notice that value of the animator of autonomous expenses can be received and directly from a balance condition on a of the benefits. At a gain of cumulative demand for the size DAD it is necessary for preservation of balance that the gain of cumulative demand was equal to an income gain:
It is also necessary to mention that according to Keynesians decrease in a real salary owing to an increase in prices does not cause decrease in the offer of work as owing to the same monetary illusions subjects are guided by a nominal rate of a salary.
The Keynesian concept is under construction on other postulates. Waugh-peryovykh, production factors in the short period are not. Secondly, the economy is not economy of the perfect competition, and labor market most . Thirdly, the nominal salary is not.
In the first quadrant the size of an effective — at is defined'. The size of effective demand is projected on the schedule of production function of the short period of y (N), demand for work at a rate of N0 the Projection of the found value of demand for work to the schedule of limit productivity as a result is defined determines the price at which businessmen agree to get number of the work N0, that is a rate of a nominal salary – W
The analysis which is carried out by the Smith showed that function of 3 type rather authentically describes behavior of house farms in the short period (till 4 years). But upon transition to more temporary intervals (10 and 30 years) Keynes's thesis about a of limit tendency to consumption and decrease of a of average norm of consumption statistically was not confirmed.
Thus – in labor market balance will remain as it will be observed WD conditions> WS. But if the curve of function of the offer of work was displaced in the situation NS', at preservation of balance in labor market employment would manage to be brought only to N' as at employment N there is more' the condition would not be satisfied: WD> WS. Then the economy would be faced by a dilemma: or in all markets, or a full employment.
