Labor Economics • Labor markets function through interactions between workers and employers. • Labor economics looks at supply of labor, demand of labor, and resulting wages, employment, and income
Resource Pricing • Money income determination: Resource prices are major factors in determining the income of households. Price firm pays for labor resource changes as wage, rent, interest, profit incomes to households that supply labor change • Cost minimization: resource prices are a cost to the firm. Company is trying maximize profit with the most cost efficient resources. Resource prices play a large part in determining quantities of land, labor, capital, and entreprenrual ability that is involved in producing each good
Resource allocation: resource prices allocate resources among industries and firms just as product prices allocate goods and services to consumers. • Policy Issues: many policy issues surround the labor market. For example, should government raise minimum wage, Should government do anything to discourage excess pay to corporate executives?
Resource Demand as a Derived Demand • Demand for any resource is an inverse relationship between price of the resource and the quantity of the resource demanded. • This demand is a derived demand. It is derived from products that the resources help produce. • Demand for a product creates the demand for the labor resource
Marginal Revenue Products • Demand of resource depends on… • The productivity of the resource is helping create a good or service • The market value of price of the good or service it helps produce
Rule for employng resources • MRP=MRC • To maximize profits a firm should hire additional units of a resource as long as each successive unit adds more to the firm’s total revenue then it does to the firm’s total cost • Marginal resource cost= • Change in total resource cost/unit change in resource quantity
MRP as resource demand schedule • In purely competitive labor markets market supply and market demand establish wage. • Each firm hires such a small percentage of the resource it can’t influence the market wage; it is a wage taker, not a wage setter. • This means each additional unit of labor hired the TRC increases by exactly the amount of the constant market wage rate
Determinates of resource demand • Changes in Product Demand: other things equal a increase in the demand for a products will increase the demand for a resource, and for a decrease in demand vice versa • Changes in Productivity: If productivity of a resource increases the demand for the resource. If the productivity of a resource decreases then demand will decrease • There are several way changes in productivity may be altered; by the quantity of other resources-marginal productivity changes, technological advance-improve quality of resource, quality of variable resource-improvements in quality of labor market
Changes in the price of other resources may change demand • Substitute resources-technology is such that labor and capital are substitutable • Substitution effect-decline in price of machinery allows firm to substitute machinery for labor • Output effect-because price of machinery has fallen, costs of producing various outputs must also decline. With lower cost firm finds itself profitable to produce and sell a greater output.
Demand for labor increases when… • Demand for product produced increases • Productivity of labor increases • Price of a substitute decreases, provided output effect exceeds substitution effect • Price of substitute increases, provided substitution effect exceeds output effect • Price of complementary good decreases
Ratio of resource cost to TC • Larger the proportion of total production costs accounted for by a product the greater the elasticity of demand for the resource
Least Cost Rule • Cost of any output is minimized when the ratios of marginal product to price of the last units of resource used are the same for each resource • With just two resources, labor and capital, a competitive firm maximizes its total cost of a specific output when • Marginal product of labor/price of labor = • Marginal product of capital/price of capital
Profit Maximization • In a competitive market a form will achieve a profit maximizing combination of resources when each resource is employed to the point where marginal revenue product equals resource price
Marginal productivity theory of income distribution • Income gets distributed according to one’s contribution to society’s output.
