This will shift the MRP curve inwards. Using the firm’s demand curves for labour to derive the industry demand curves for labour O Q of labour 163。 MRP2 W1 MCL1 MCL2 W2 MRP1 a b c The industry demand for labour is the horizontal sum of the green lines (connecting points a and c) Using the firm’s demand curves for labour to derive the industry demand curves for labour Wages under perfect petition ? Wages and profits under perfect petition ? MRP slopes down, thus last worker adds less to revenue than previously employed workers ? if all workers are paid the MRP of the last worker , there is a surplus for the firm over its wage bill, contributing to profits O MCL = W W Qe Q of labour 163。 MRPL Wages and profits Profit maximised at employment of Qe O MCL = W Surplus for firm Wages W Qe Q of labour 163。 MRPL Wages and profits Wages under perfect petition ? Equality and inequality of wages under perfect petition ? equality will exist when: ?workers have identical abilities ?there is perfect knowledge ?there is perfect mobility of labour ?all jobs are equally attractive to all workers ?wages determined entirely by demand and supply Wages under perfect petition ? In practice, inequality of wages between markets will persist under perfect petition ? jobs are not identical ? workers’ abilities are not identical ? workers are not perfectly mobile ? Factors that contribute to poverty under perfect petition include ? lack of skills that increase productivity ? participation in labour markets with high level of supply/ low demand ? working in contracting industries Theory of the Distribution of Ine Wage Determination in Imperfect Markets Wages in imperfect markets ? Firms with monopsony power in employing labour ? MCL W ? effects on wages and employment O Q of labour 163。 MRPL ACL ???W (supply curve) Q1 MCL Monopsony W1 Q2 W2 Profit maximised where MCL = MRPL Perfectly petitive equilibrium Wages in imperfect markets ? Other labour market imperfections
