Resource Markets & Pricing • Still ‘Supply & Demand’ • Difference: • Firms Demand • Households Supply
Derived Demand • Firms Demand • Motivation: Maximize Profits • No inherent desire or need for resource • Product market issues may affect demand
Derived Demand & Supply • Households Supply • Motivation:Maximize Utility • Depends on $ Opportunity Cost • derived from households' utility maximization • Utility received may be a form of “payment”
Should A Firm Hire Another Worker? • Yes, if it adds to profits: • Worker adds to physical output: • Marginal Product • Value of Marginal Product when sold: • MP x Price = Marginal Revenue Product (MRP) • a.k.a. Value of Marginal Produce • MRP is the marginal benefit • Cost of hiring the worker (worker’s wage) is marginal cost – called Marginal Resource Cost (MRC) • IF MRP > MRC yes, hire the worker • Keep hiring until MRP = MRC
Marginal Revenue Product and Marginal Resource Cost Profit Maximization when the quantity of resource purchased results in: MRP = MRC
Shifts in Demand for Resources • Anything that changes MR, MRP, or MRC: • Changes in Prices of other resources • Complements • Substitutes • Changes in Technology • Changes in Demand for Final Product
Wages & “Economic Rents” • Total Returns to Resources • Total Payment: = P x Q • Resource Opportunity Costs • Next highest paying use or opportunity • Economic Rent is payment greater than opportunity cost • “Unearned” or “unnecessary” payment
Why Actual Wages Differ From Value of Marginal Product • Market Power • Sellers’ Power: • Unionization • Unique Skills or Inelastic Supply • Licensing
Why Actual Wages Differ From Value of Marginal Product • Market Power • Buyers’ Power: • Monopsony • Bargaining Power • Superior Information
Why Actual Wages Differ From Value of Marginal Product • Non-Market Reasons: • Discrimination • Efficiency Wages • Compensating Differentials • Risk • Image • Conditions • Security
