Consider the labour market represented in the following graph: real wage W P equilibrium employment WS PS Employment rate Where WS represents the Wage Setting relationship, and PS represents the Price Setting relationship. Which of the following statements are INCORRECT? Changes in the marginal product of labour will change the equilibrium level of unemployment because it makes the wage setting (WS) curve shift. A non-labour related increase in cost of production, will shift the PS curve downwards. The PS curve is horizontal because changes in prices do not affect the rate employment in the economy. A positive demand shock that increases actual output will move the equilibrium employment to the right of the point E in the graph.

In a country called Uncle Sam Land (USL), the labor demand curve is given by:W = K- 4LWhere W is the wage rate, K is a variabledetermined by accumulated capital stock in thecountry, and L is the labor force in the country.K= 50 is supplied by the capitalists.If the labor force in this country goes up from 10 to 11, what happens to the national income in USL?National Income = income of all workers + income of all capitalists.Select one:a. Does not changeb. Goes down by 44c. Goes up by 8d. Goes up by 26e. None of the above.

The labour market in an economy is characterised by the following equations: Wage setting: Price setting: W p² W Р = 0.9-0.5u = 1 1+µ -A In which W is nominal wages, pe and P are expected nominal prices and nominal prices, respectively, u is level of unemployment. µ is the price mark-up and λ is the marginal product of labour. Assume μ = 0.3 and λ = 1.1 Considering this information, which of the following statements are CORRECT: Improvement in working conditions will have no effects in the equilibrium level of unemployment in this economy. If this economy's actual output is below its potential output, there is pressure for real wages to decrease below 0.85 (i.e., W<0.85). If price marginal product of labour decreases to 1, the equilibrium real wage in this economy will decrease. A positive demand shock will change the equilibrium variables in this economy.
