Elasticity of Labour Demand Essays -- Economics

Elasticity of Labour Demand Labour is a derived rent realised by the assume for the product thatthe grasp leave behind be producing. The theory of motor demand explainsthe behaviour of the firm with the key principle being to achieve theoptimal amounts of grasp employers will want to utilise at differentwage levels.We essential make several assumptions when describing how the long runlabour demand is derived. Firstly we must assume that firms are profitmaximisers and therefore will attempt always to minimise any costsincurred. Further assumptions to simplify analysis of labour demandare that there are no costs of employment other than hourly wages andproductivity of labour is independent of time worked. I.e. Labour ishomogenous.The toil process involves only two inputs, Labour (L) andCapital (K)The firms production functions in the short and long runqSR = f(K, L)qLR = f(K, L)In the long run, the firms ceiling stock is non fixed at any level Kis now changeable as opposed to the short-run where the firm isburdened with a stock of capital that might non be the optimal levelunder the current market conditions. In the indeterminate long runperiod, the firm will therefore be able to select optimalcombinations of its variable stock. A firm will now have much than onetool to expenditure in order to capitalize on profits. The only long runconstraint of the firm would be given by technology.To find the preferred preference of inputs we can examine differentquantities of K and L given the ratio of the input prices with a levelof output. These choices are depicted in a crimp called an isoquant.An isoquant demonstrates a set of points where output is identical butdifferent combinations of labour and capital are possible.Diagram IsoquantCriteria Isoquants are downward sloping Isoquants can not intersect A higher isoquant is associated with a higher level of output An isoquant must be convex to the origin (displaying diminishing returns to scale)The slope of t he isoquant is derived by lamentable between two points onthe curve. Moving from A to B will maintain the level of output butchange the ratio of inputs. In this end it will lower the capitalstock from K1 to K2 but increase the level of employment from L1 to L2.Output is decreased by the units of capital stock cut multiplied bythe marginal product of capital, but i... ...as I have summarised), a one percent rise in the wage leads to a 30per cent drib in employment levels. Private strategies are alsoaffected, as a unions bargaining strategy will be influenced by theelasticity. The more inelastic the employers demand for labour, thestronger the negotiations will be to oppose a wage cut. Unions wouldbe more uncompromising when offered a lower wage.ReferencesBooks- Borjas, G.
