Slide 1 Estimating Cost Functions • Firms want to know what their costs are now, what their costs will be, and what they would be at different output levels. • Costs issues involve the type of cost (fixed, variable, average, etc.) and issues of time depreciation. » Items often depreciate with use » Items can also depreciate with passage of time • Because prices of inputs change with inflation, must consider deflating or detrending cost data. © 2011 Cengage Learning.

Slide 2 Short Run Cost-Output Relationships • Typically use TIME SERIES data for a plant or for firm, regression estimation is possible. • Typically use a functional form that “fits” the presumed shape. • SRTC is often CUBIC SRTC = a+bQ+cQ2+dQ3 cubic is S-shaped • STAC is often QUADRATIC or backward S-shaped SRAC = a+bQ+cQ2 quadratic is U-shaped or arch shaped. © 2011 Cengage Learning.

Slide 3 Empirical Cost-Output Polynomial: In Theory • • • • • Short run cost functions can be represented by a cubic relationship TC = a + bQ + cQ2 + dQ3 From this we can find ATC (average total cost) ATC = TC/Q = a/Q + b + cQ + dQ2 We can also find MC (marginal cost) MC = dTC/dQ = b + 2cQ + 3dQ2 Notice that both ATC and MC are U-Shaped as represented by quadratic equations (to the power of 2) Notice also that if “d” is insignificant, the form is even simpler as the last term is zero in each of the above examples © 2011 Cengage Learning.

Find the AC function. What is MC at Q=10? 3. Find the MC function. What is MC at Q=10? 1. TC = 1000 + 50 Q - 10 Q 2 + 2 Q3 t-values in the (1.25) (2.5) (4) (2) parentheses 2. AC = 1000/Q + 50 - 10 Q + 2 Q2 3. MC = 50 - 20 Q + 6 Q2 NOTE: Total cost is S-shaped Average cost is U-shaped And even MC is U-shaped Find AC at Q=10. Find MC at Q=10. AC = 1000/10 + 50 – 10(10) + 2(10)2 = 250 MC = 50 – 20 (10) + 6 (10)2 = 100 = 450 © 2011 Cengage Learning. All Rights Reserved.

Slide 8 Engineering Cost Approach • Engineering Cost Techniques offer an alternative to fitting lines through historical data points using regression analysis. • It uses knowledge about the efficiency of machinery. • Some processes have pronounced economies of scale, whereas other processes (including the costs of raw materials) do not have economies of scale. • Size and volume are mathematically related, leading to engineering relationships. Large warehouses tend to be cheaper than small ones per cubic foot of space. © 2011 Cengage Learning. All Rights Reserved.

Slide 9 Survivor Technique • The Survivor Technique examines what size of firms are tending to succeed over time, and what sizes are declining. • This is a sort of Darwinian survival test for firm size. • Presently many banks are merging, leading one to conclude that small size offers disadvantages at this time. • Dry cleaners are not particularly growing in average size, however. © 2011 Cengage Learning.

Slide 10 Break-even Analysis • We can have multiple B/E (break-even) points with non-linear costs & revenues. Total • If linear total cost and total revenue: Cost » TR = P•Q » TC = F + V•Q • where V is Average Variable Cost Total • F is Fixed Cost Revenue • Q is Output • cost-volume-profit analysis B/E B/E Q © 2011 Cengage Learning.

Slide 12 Answer: Q = 40,000/(2,000)= 40/2 = 20 garages at the break-even point. Break-even Sales Volume • • Amount of sales revenues that breaks even P•Qb = P•[F/(P-V)] = F / [ 1 - V/P ] Ex: At Q = 20, B/E Sales Volume is $9,000•20 = $180,000 Sales Volume Variable Cost Ratio © 2011 Cengage Learning.

Slide 14 Contribution Analysis • • Another variation is to find if added sales through a ad campaign or new product is justified. It looks at the incremental contributions and incremental additions to cost. Do the project if: » Added Contribution > Added Cost » (P – v) DQ > D Direct Fixed Cost » When this inequality holds, the project adds more to revenues than it adds to cost. Limitations of B/E & Contribution Analysis Sometimes the assumptions do not hold 1. Costs may be semi-variable 2. Many times firms sell multiple products or small, medium, and large varieties 3. There is uncertainty as to the P, V, and F in the problem 4. Inconsistency in the planning horizon © 2011 Cengage Learning. All Rights Reserved.

Slide 17 Break-Even Analysis and Risk Assessment • One approach to risk, is the probability of losing money. • Let Qb be the breakeven quantity, and Q is the expected quantity produced. • z is the number of standard deviations away from the mean • z = (Qb - Q )/ ^ • 68% of the time within 1 standard deviation • 95% of the time within 2 standard deviations • 99% of the time within 3 standard deviations Problem: If the breakeven quantity is 5,000, and the expected number produced is 6,000, what is the chance of losing money if the standard deviation is 500? Answer: z =(5000 – 6000)/500 = -2. There is less than 2.5% chance of losing money. Using table B.1, the exact answer is .0228 or 2.28% chance of losing money. © 2011 Cengage Learning.

Slide 18 Prices, Output, and Strategy: Pure Competition and Monopolistic Competition • Pure competition is a standard against which other market structures are compared. In it, there are many firms and the product is perfectly undifferentiated. There are industries where are many firm, but the products or service are heterogeneous or differentiated. • Monopolistic competition is when there are many firms, but the product or service is differentiated. This brand competition may involve advertising campaigns and large promotional expenditures to stress often minor distinctions among products © 2011 Cengage Learning. All Rights Reserved.

Slide 21 Generic Types of Strategies to Attain Sustainable Profits • Product Differentiation Strategy » A strategy that relies upon differences in products or processes affecting perceived customer value. » For example, Coca-Cola or Nestlé • Cost-based Strategies » A strategy that relies upon low-cost operations, marketing, or distribution. For example, Southwest Airlines & Dell Computers • Information Technology Strategy » Use IT capabilities to distinguish yourself from others » For example, Allstate Insurance & GPS tracking to offer lower insurance rates to those who don’t drive their best cars to work © 2011 Cengage Learning.

Slide 22 The Relevant Market Concept • A market is a group of economic agents that interact in a buyerseller relationship. The number and size of the buyers and sellers affect the nature of that relationship. • A popular measure of concentration is the percentage of an industry comprised of the top 4 firms. Similarly, the market share held by the top 4 buyers is a popular measure of buyer concentration. • The relationship among firms is affected by: a. the number of firms and their relative sizes. b. whether the product is differentiated or standardized. c. whether decisions by firms are independent or coordinated (collusion). © 2011 Cengage Learning.

Slide 23 Michael Porter’s Five Forces of Competitive Advantage The forces that determine competitive advantage are: 1. The Threat of Substitutes can be offset by brands, complementors, and special functions served by the product. 2. The Threat of Entry can be reduced by high fixed costs, scale economies, restriction of access to distribution channels, or product differentiation. 3. The Power of Buyers from the threat of concentration of buyers. 4. The Power of Suppliers for the threat when concentrated suppliers of key inputs affect profitability. 5. The Intensity of Rivalry impact profitability via market concentration, price competition tactics, exit barriers, ratio of FC to TC (cost fixity), and industry growth rates. © 2011 Cengage Learning.

Slide 25 Break-even Sales Change Analysis The price-cost margin percentage (PCM) is defined as PCM = ( P – MC )/P. A price cut may help or hurt profitability depending on price elasticities and price cost margins. We can ask how much quantity must change after a price cut to breakeven (from before the price cut)? If we cut prices 10%, to breakeven, the percentage change in quantity (DQ/Q) must be large enough to satisfy the equation to breakeven: PCM / (PCM – .10) < (1 + DQ/Q ) The larger is the price-cost margin percentage, the smaller will be the necessary quantity response to justify cutting price. If PCM is 80%, then .8/(.8-.1) = 1.14. Hence, a 10% cut in price must be offset by only a 14% increase in quantity to breakeven. If PCM is only 20%, then .2/(.2-.1) = 2. Hence, a 10% cut in price must be offset by at least a 20% increase in quantity to breakeven. So with Hanes underwear and low PCM discourages discounting. © 2011 Cengage Learning.

Slide 26 There is a continuum of market structures: Pure Monopolistic Competition Competition Monopoly 1. 2. 3. 4. Best Pure WorstCompetition Oligopoly assumes: a very large number of buyers and sellers homogeneous product (standardized) complete knowledge of all relevant market information free entry and exit (no barriers) These assumptions imply several things about competitive markets, including price equals average cost in the long run. © 2011 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part. Slide 27 1. 2. 3. 4. 1. 2. 3. 4. Monopoly assumes: Only one firm in the market area Low cross price elasticity with other products. No interdependence with other competitors. Substantial entry barriers These assumptions imply that the monopoly price is well above marginal cost. Monopoly is discussed in full in Chapter 11. Monopolistic competition assumes: A large number of firms, some of which may be dominant in size Differentiated products Independent decision making by individual firms Easy entry and exit These assumptions imply several things about monopolistic competition, including that the price in the long run is equal to average cost. © 2011 Cengage Learning.

Products may be differentiated or undifferentiated 3. There is a large degree of interdependence with other competitors • These assumptions imply several things about monopolies, including that the monopoly price is well above marginal cost. • After going briefly over these four market structures, this chapter examines: » Pure Competition » Monopolistic Competition © 2011 Cengage Learning.

Slide 29 CHARACTERISTICS OF DIFFERENT MARKET ORGANIZATIONS Although not every industry fits neatly into one of these categories, the categories do provide a useful and convenient framework for thinking about industry structure and behavior. Slide 30 Price-Output Determination Under Pure Competition Competitive firms attempt to maximize profits. Competitive firms cannot charge more than the market price of others, since their product is identical to all others. Hence, competitive firms are price takers. Total revenue, TR, is P·Q, where price is given. Therefore, marginal revenue, MR, is price, P. Profit () is total revenue minus total cost, that is: = TR TC. © 2011 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part. Slide 31 Profit maximization implies that each firm produces an output where Price = Marginal Cost (P = MC). » To produce more than this quantity implies that P < MC, which is not the most profitable decision. » To produce less than where P=MC, implies that P > MC, and the firm could increase profits by expanding output. • In short run, a competitive firm may earn economic profits. • In long run, entry pushes price down to the minimum point of the average cost curve, so that economic profits are zero. © 2011 Cengage Learning.

If P = MC for each firm, then each firm is doing what it thinks maximizes profits. Firms are in MC MC equilibrium. 2.

Slide 33 A Competitive Market in the Long Run • Industries which have economics profits draw entry and shift the MC1 curve out to MC2 where there is no reason for more firms to enter or firms to exit the industry • Price covers all cost, so in the LR, P=AC which means that Economic Profits are zero.

Slide 34 Long Run Competitive Markets with external diseconomies of scale Figure 10.5 $/barrel for oil Brazilian Ethanol Mexican Oil Persian Gulf Oil • As demand rises for products, we find that inputs become more expensive. • The rising cost is not due necessarily to the productivity of the firms, but higher prices for what they purchase. • One example is the rising price for crude oil. • As demand in the world increases, D2 the marginal seller of oil is ever pricier.

Slide 41 Selling and Promotional Expenses • Suppose that the price is determined outside of the model, as with liquor prices in some States. • We will expand promotional activities until the extra profit associated with the activity equals the extra cost of the promotion. • This decision rule for Optimal Advertising is when: Contribution Margin = Marginal Cost of Advertising or P – MC = k • DA/DQ or expand advertising whenever (P – MC)( DQ/DA) > k • where, contribution (P – MC) is the marginal profit contribution of an additional sale, and the marginal cost of advertising is ( k • DADQ). © 2011 Cengage Learning.

Slide 44 Search Goods versus Experience Goods • Search goods are products or services whose quality is best detected through a market search. • Experience goods are products and services whose quality is undetected when purchased. • Warranties and firm reputations are used to assure quality. • But if someone is selling his or her car, isn't it likely that the car is no good? Is it a lemon? » This is an explanation why used car prices are so much lower than new car prices. • If one firm defrauds customers, how do the reputable firms signal that they are NOT like the fraudulent firm? © 2011 Cengage Learning.

Slide 45 Adverse Selection and the Notorious Firm • Suppose that a firm may decide to produce a High Quality or Low Quality product, and the buyer may decide to offer a High Price or a Low Price. • Since the firm fears that if it offers a High Quality product but that buyers only offer a Low Price, they only produce Low Quality products and receive Low Prices. • This is the problem of adverse selection © 2011 Cengage Learning.

Slide 46 Notorious Firm Analysis Payoffs in the boxes are for the seller only • Simultaneous decisions BUYER of buyer & seller Hi Price Low Price • A risk averse decision High by the firm is to make a 70 Quality 130 Low Quality product SELLER • Best for the buyer is a Low 150 90 Quality low price, but a high quality good.

Slide 47 Solutions to the Problem of Adverse Selection • Regulation (Disclosure Laws, Truth in Lending) • Reliance Relationships are long term, mutually beneficial agreements, often informal. • Brand names (a form of a “hostage” to quality) • Nonredeployable assets are assets that have little value in another other use Example: Dixie Cups made with paper-cup machinery which cannot be used for other purposes — if Dixie Cups leak, the company is in trouble © 2011 Cengage Learning.

Slide 48 Credible Commitments • A credible commitment is a conditional strategy for establishing trust by promising to make the promise-giver worse off by violating that trust » such as a promise of product replacement if the product ever fails. Examples: 1. Dooney & Bourke promise life-time replacement of handbags 2. Other firms have sometime promised: If any of my products fail to work, I will pay the buyer three-times their purchase price in recompense! Clearly, this commitment makes the firm worse off if they sell shoddy goods. 3. Brand names are a “bond” or “hostage” lost if products fail to live up to promises. © 2011 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part. Slide 49 Mechanisms for commitments • Use of nonredeployable assets such as reputation. Once lost, a good reputation is hard to rebuild. • Entering into alliance relationships which would fall apart if any party violated their commitments. • using a "hostage mechanism" that is irreversible and irrevocable can deter breaking commitments. » Examples are "double your money back guarantees," and "most favored nation" clauses. © 2011 Cengage Learning.
