Supply Chapter 5

Goals & Objectives 1.Supply Curve & Price 2.Changes to supply. 3.Theory of Production. 4.3 Stages of Production. 5.4 Measures of Cost. 6.Identify 2 key measures of revenue. 7. Business Decisions & Gov’t

Supply Amount of a product offered for sale at all possible prices that could prevail in the market. Law of Supply: principle that suppliers will normally offer more for sale at higher prices rather than lower prices.

Supply & Price

Change in Supply 1. Cost of Inputs: Labor wages (minimum wage increases?), gasoline prices, capital goods prices, property taxes, business taxes, gov’t regulations 2. Productivity: Commission, Sales, Piece- work, fringe benefits, 401K, profit sharing.

Minimum Wage Requirements are Input Costs

Change in Supply 3. Technology: Robotics, Computers, Smart Cars, Smart phones, Wireless 4. Taxes and Subsidies: High taxes lowers profit margins which lowers production and raises consumer prices. – Subsidies: designed to protect producers profits. Short Run: lowers consumer prices – Long Run: Reduces competition and raises prices without continued subsidies.

Supply & Taxes

Change in Supply 5. Expectations: Futures/Options. – Gasoline prices… Investors expect oil prices to rise due to gov’t regulations, investors buy more oil stock, causes the price of oil to rise which causes gasoline prices to rise, investors make dividends. – Hurricane & Gas Prices: Hurricane shuts down supply of oil which causes a shortage of gasoline which causes increased gasoline prices. (JIT theory) 6. Government Regulations: Global Warming Scheme; shuts down pipeline & drilling on public lands which causes artificial oil shortages & high gasoline prices.

Regulations & Supply

Change in Supply 7. Number of Sellers: – Increased number of sellers/producers/competing business will cause an increase in production and lower consumer prices. – Decrease number of sellers/producers/competing business will cause a decrease in production and higher consumer prices. – Cost-Push Inflation: government licensing requirements, increased taxation & regulations decrease the number of producers & high prices.

Community Reinvestment Act Fannie Mae & Freddie Mac Federal Requirement for Banks to issue loans to borrowers with no credit history or poor credit history. Trade Off: Increased default rate for banks. Increased foreclosures and higher collateralized debt obligations, fewer profits. Opportunity Costs: Less money to lend to qualified borrowers & higher interest rates.

Sub-Prime Loans & Inflation

Theory of Production How does Obamacare Affect the theory of production? SHORT RUN: Ford Motor Co. hiring 300 temporary workers instead of full time employees. 29ers? Obamacare and full time employee costs. LONG RUN: Ford Motor Co. building a new factory. Re-tooling/designing 49ers? Obamacare and fringe-benefit costs.

29ers & Obamacare

49ers & Obamacare

3 Stages of Production 1.Increasing returns: More workers equals increased productivity. Greater supply equals greater profits. (6 employees) 2.Diminishing returns: Workers at marginal production rates creates increased costs and break- even profits. (10 employees) 3.Negative returns: Too many workers at marginal production rates creates costs exceeding profits. (11 employees)

Measures of Cost 1. Fixed Costs: Land, Leases, Mortgages, Capital Goods Costs, Utility Costs, Property Taxes, Sales Taxes, Income Taxes, License Fees, Insurance Costs, Employee Benefits 2. Overhead: Sum total of all fixed costs.

Fixed Costs/Overhead

Measures of Cost 3. Variable Costs: Labor and Resource Costs 4. Total Costs: Sum Total of Fixed and Variable Costs. 5. Marginal costs: producing more than needed. (JIT Theory)

E-COMMERCE  Avoids advertising Costs, Taxes and Regulations  Internet is the last unregulated commerce market.  State and Local Governments demand federal interstate commerce regulation.  Why? Who Benefits from regulation?  Who loses from regulation and taxation?

Measures of Revenue  Break-even point: 1.Total Costs: Variable + Fixed + Marginal 2.Subtracted By: 3.Total Revenue: Total output multiplied by units sold. 4.Break-Even Point: Total revenue needed to pay for total business costs. 5.Marginal Revenue: Additional output past break-even point.
