If firms adjust in the short run their production of goods to the demand for goods, they will also adjust their labor demand to the demand for goods in the short run.
Consequently, in the short run, the labor demand of firms is, under Keynesian assumptions, not determined by the real wage w/P and the given capital stock K1, i.e. by LD(w/P,K1), but by the demand for goods YD.
The "short-run" demand for labor therefore equals LD(YD)LD (w/p,K1)

LD(YD,2)
If the "short-run" demand for labor equals LD(YD) and if the real wage is downward fixed by a collective bargaining contract to the long-run market equilibrium level of w1/P1, a reduction of the demand for goods from the normal capacity GDP to a level of YD,2 will cause unemployment.This unemployment emerges despite the fact that the real wage equals the long run equilibrium value of w1/P1!It is therefore no neoclassical unemployment but "Keynesian unemployment".

If the "short-run" demand for labor equals LD(YD) and if the real wage is downward fixed by a collective bargaining contract to the long-run market equilibrium level of w1/P1, an increase in the demand for goods from the normal capacity GDP to a level of YD,2 will cause overemployment.In order to get additional workers, firms must increase real wages in the short-run from w1/P1 to w2/P1.

„In 1913 the Ford Motor Company started paying its worker 5 $ per day. The prevailing wage at the time was between 2 $ und 3 $ per day, so Ford’s wage was well above the equilibrium level. Not surprisingly, long lines of job seekers waited outside the Ford plant gates hoping for a chance to earn this high wage“ (Source: Mankiw, Macroeconomics , p. 167)(Source: Mankiw, Macroeconomics , p. 167)

Business Report of the Ford Motor Company from 1913:
„The Ford high wage does away with all the inertia and resistance. (…) The workingmen are absolutely docile, and it is safe to say that since the last day of 1913, every single day has seen major reductions in Ford shops’ labor costs.” Absenteeism fell by 75 %, suggesting a large increase in worker effort. Ford and his associates freely declared on many occasions that the high wage policy had turned out to be good business.

➤ Current Example for Efficiency-Wages:Current Example for Efficiency-Wages:
„The automotive supplier Leoni currently employs more than 23000 workers worldwide. Thereby, Leoni primarily selects production locations with a low wage level. However, at such locations Leoni pays relatively generous wages. For example, in a plant of Leoni in Stryi, Ukraine, Leoni pays significantly more than the local minimum wage, which equals 650 Griwna (100 Euro). Furthermore, Leoni voluntarily offers lunches at reduced costs as well as free health insurance. Such benefits are not common standard in the Ukraine.”

➤ Minimum Wages in Germany:
■In Germany labor unions and employer associations can set minimum wages for their sectors. They are, however, only binding for firms that are members of employer associations, what is the case for 57% of West German employees and of 41% of East German employees.
■The federal minister for labor is, however, entitled by law to declare such collective wage agreements for generally binding in sectors where more than 50% of all employees are labor union members and the employers associations of these sectors agree.

➤ Minimum Wages in Germany:
■Labor unions like DGB, IG-Metall and NGG demand a general minimum wage of 8,5 €
■The Ifo-Institute (Munich) expects a loss of about 1,1 million jobs at a minimum wage of 7,5 €.
■The Council of Economic Advisers of Germany guesses that only a minimum wage not higher than 5 € will have no negative unemployment effects.
■A minimum wage of 7,5 € would increase the wages of about 10% of all employees in Germany.
