Example: Bilateral Monopoly in Labor Market
Seattle -- At the heart of the union machinists' strike against Boeing Co. is a high-stakes showdown over something the aerospace giant once touted as a manufacturing innovation: Its effort to outsource key roles in producing its new 787 Dreamliner jet. Nearly 27,000 machinists walked off the job at 12:01 a.m. Saturday after last-ditch talks for a new three-year contract failed. While wages and health-care costs are big issues, job security has emerged as perhaps the most crucial one, with both sides signaling that the new contract represents a major crossroads.
The machinists' strike is a classic illustration of the bi-lateral monopoly model. ハハ The Boeing labor union represents a monopoly seller of aircraft worker services, in the diagram its wage demand demand is represented by the Monopoly Wage of $15. ハ The Boeing management represents a monopsony buyer of aircraft worker services, in the diagram its wage offer is represented by the Monopsony Wage of $8.

— In Hollywood, the West Coast capital of conventional wisdom, several theories about the Writers Guild strike are widely held: The longer writers and their production patrons stay away from the negotiating table, the harder it'll be to come back; no side is likely to emerge unscathed; As the second week of the strike begins, layoffs have already spread across parts of the TV sector and hostility is growing,.

Example of Supply Decrease
© 2006 Thomson/South-Western
— The apprehension on Wednesday of more than 1,100 illegal immigrants employed by a Houston-based pallet supply company, as well as the arrest of seven of its managers, represents the kickoff of a more aggressive federal immigration enforcement campaign intended to hold employers accountable for breaking the law, Homeland Security Secretary Michael Chertoff said today.

2.1 Demand Curve: Marginal Revenue Product
The demand curve for a resource is derived from the marginal product of the input and the marginal revenue from selling that output . This demand curve is the marginal revenue product curve for that factor
Marginal product is the change in total product from employing one more worker and reflects the law of diminishing returns
Marginal revenue is the change in total revenue associated with the sale of the output produced by the factor.
The slope of the demand curve depends on the structure of the output market. If sold in a perfectly competitive market the slope is flatter, in a monopoly market, the slope is steeper.
Begin 2 Market 4 Shifts 5 M & M3 Adjustment 6 Labor End8
2.1a Output sold in Perfectly Competitive Market Here, marginal revenue product is the marginal product of the resource
multiplied by the product price of $20, the marginal benefit from hiring one more worker
Note that because of diminishing returns, the marginal revenue product falls steadily as the firm employs additional units of the resource.

2.1b Output sold in Monopoly Market If the firm has some market power over the price that it charges, the demand curve
slopes downward and price must be lowered to sell more The profit-maximizing firm should be willing and able to pay as much as the
marginal revenue product for an additional unit of the resource The marginal revenue product for the price maker declines because of the law of
diminishing returns and because additional output can be sold only if the price is lower

2.2 Supply Curve: Marginal Resource Cost
The additional cost to the firm of employing one more unit of labor
Since the typical firm hires such a tiny fraction of the available resources, its employment decision has no effect on the market price of that resource
Each firm usually faces a given market price for the resource and decides only on how much to hire at that price

Begin 2 Market 4 Shifts 5 M & M3 Adjustment 6 Labor End14
3.1 Differences in Resource Prices
Resource prices sometimes differ temporarily across markets because adjustment takes time
The differences can be between industries, or geographic regions When resource markets are free to adjust, price differences
trigger the reallocation of resources, which equalizes payments for similar resources
Not all resource price differences cause a reallocation of resources For example, land may lead to permanent differences in prices Certain wage differentials stem from the different costs of acquiring
the education and training required to perform particular tasks Other earning differentials reflect differences in the nonmonetary
aspects of similar jobs

3.1a Example: Differences in Demand Market for Carpenters •Differences in the demand for carpenters in alternative uses•If carpenters earn $25 an hour to build homes (panel a), $5 more than carpenters making furniture (panel b), some will move from furniture making to home building: the wage in home building decreases and the wage in furniture building increases. Eventually, this shift will continue until the wage is equal at $24 in both markets.

4.3a Complements: Gasoline & SUVs: I
Americans have cut back gasoline use in apparent response to increasing prices, separate surveys by the government and a petroleum trade organization showed Wednesday. Gasoline prices — which average $2.801 nationwide, are up 57.7 cents from last year, according to motorist organization AAA. Gas use last month was 0.6% less than a year ago, the American Petroleum Institute reported.
High fuel prices have led to decreased quantity demand for gasoline and other refined oil products.

4.5 Demand for the Final Product
Because the demand is derived from the demand for the final output, any change in the demand for output will affect resource demand
For example, a decrease in the demand for automobiles will decrease their market price and decrease the marginal revenue product of autoworkers and other resources employed by the automobile industry

4.5a Example: Iraq War & Big Tires
Mining companies are complaining about a shortfall in the supply of the giant tires that go on large dump trucks and other heavy equipment. These outsize tires stand as tall as 12 feet tall and can spread 4 feet wide. prices have quadrupled for some of them in the last year to more than $40,000 a tire.
By SIMON ROMERO Published: April 20, 2006
There are several reasons for the tire shortage. Demand is soaring, with greater needs by the military for the wars in Iraq and Afghanistan and by construction firms rebuilding the hurricane-ravaged Gulf Coast.
In many ways, the tire shortage contributes to the soaring commodities prices. The price of copper, which is used in electrical wiring and pipes, has climbed 45 percent this year, closing at $2.9595 a pound on Wednesday. Nickel, used to make stainless steel, is up 37 percent during the same period, while gold is up 23 percent and zinc is up 65 percent.
Some companies have been forced to idle their heavy equipment
In the meantime, salvage firms are doing a thriving business in discarded tires and companies that retread tires are struggling to keep pace with demand, with used tires in some cases fetching higher prices than new tires.

5.1 Monopsony Characteristics
Single Buyer: First and foremost, a monopsony is a monopsony because it is the only buyer in the market. The word monopsony actually translates as "one buyer." As the only buyer, a monopsony controls the demand-side of the market completely. If anyone wants to sell the good, they must sell to the monopsony.
No Alternatives: A monopsony achieves single-buyer status because sellers have no alternative buyers for their goods. This is the key characteristics that usually prevents monopsony from existing in the real world in its pure, ideal form. Sellers almost always have alternatives.
Barriers to Entry: A monopsony often acquires and generally maintains single buyer status due to restrictions on the entry of other buyers into the market. The key barriers to entry are much the same as those that exist for monopoly: (1) government license or franchise, (2) resource ownership, (3) patents and copyrights, (4) high start-up cost, and (5) decreasing average total cost.

5.1a Modern Monopsony
Like other extreme market structures (perfect competition and monopoly) monopsony is only approximated in the real world. Achieving the status of THE ONLY BUYER is not easy. Few if any buyers actually achieve this status. However, several have come close. In modern times a few examples of markets that come very close to monopsony come from the world of sports.Should a talented quarterback wish to obtain a job as a professional football player, then THE employer is the National Football League (NFL). Of course, the NFL is not absolutely the ONLY employer. Employment as a professional football player can also be found with the Canadian Football League (CFL). However, sufficient difference exists between these two employers to give the NFL significant monopsony control.
Begin 2 Market 4 Shifts 5 M & M3 Adjustment 6 Labor End32
5.1b Monopsony Supply and CostSingle-buyer status means that monopsony faces a positively-sloped supply curve, such as the one displayed in the exhibit to the right. In fact, the supply curve facing the monopsony is the market supply curve for the product.The far right curve in the exhibit is the red supply curve (S) facing the monopsony. The far left curve is the brown marginal factor cost curve (MFC). The marginal factor cost curve indicates the change in total factor cost incurred due to buying one additional unit of the good.Because a monopsony is a price maker with extensive market control, it faces a positively-sloped supply curve. To buy a larger quantity of output, it must pay a higher price. For example, the monopsony can hire 10,000 workers for a wage of $5. However, if it wants to hire 20,000 workers, then it must raise the wage to $6.10.
For this reason, the marginal factor cost incurred from hiring extra workers is greater than the wage, or factor price. Suppose for example that the factor price needed to hire ten workers is $5 and the factor price needed to hire eleven workers is $5.10. The marginal factor cost incurred due to hiring the eleventh unit is $6.10. While the $6 factor price means the monopsony incurs a $5.10 factor cost from hiring this worker, this cost is compounded by an extra cost of $1 due to the higher wage paid to the first ten workers. The overall increase in cost, that is marginal factor cost, is thus $6.10 (= $5.10 + $1).
Begin 2 Market 4 Shifts 5 M & M3 Adjustment 6 Labor End33
5.1c Profit-maximizing employment of a monopsony
This firm faces a positively-sloped supply curve, represented by the red supply curve (S). Because higher wages are needed to attract more labor, the positively-slope brown curve is the marginal factor cost curve (MFC). The third curve displayed in the exhibit is the green negatively-sloped marginal revenue product curve (MRP), which indicates the value of the extra production generated by each worker.As a profit-maximizing firm, monopsony hires the quantity that equates marginal factor cost and marginal revenue product found at the intersection of the MFC and MRP curves. This quantity is 37,000 workers. The monopsony then pays each worker $8.40.
•This price and quantity maximizes profit because the revenue generated from hiring the last worker (marginal revenue product) is exactly equal to the cost incurred from hiring the last worker (marginal factor cost).

5.2a MONOPSONY & MINIMUM WAGE: Con
The standard analysis of a minimum wage price floor assumes a perfectly competitive market with a large number of sellers and buyerswhen a minimum wage is imposed on this efficient, competitive market the minimum wage disrupts this competitive equilibrium and creates a surplus of unemployed workers.
Sourceof the material in the slides on Monopsony and Minimum Wage
A $12 minimum wage in the diagram creates 13,500 unemployed workers, workers who are willing and able to work at the $12
minimum wage, but who cannot find employment.
Begin 2 Market 4 Shifts 5 M & M3 Adjustment 6 Labor End37
5.2b MONOPSONY & MINIMUM WAGE: Pro
Now consider how a $10 minimum wage affects a monopsony market. By imposing a minimum wage, the portion of the supply curve that carries a factor price less than $10 is no longer relevant. The factor supply curve now consists of two segments. The first segment is horizontal at the $10 wage. The second segment is the original factor supply curve above the $10 wage.The change in factor supply also cause changes in the marginal factor cost. The marginal factor cost curve coincides with the horizontal segment of the factor supply curve up to 50,000 workers. At 50,000 workers the marginal factor cost curve then turns vertical until it joins the original marginal factor cost curve.The profit-maximizing outcome is where marginal factor cost and marginal revenue product intersect. This occurs at the $10 minimum wage and 50,000 workers. This is, by no coincidence, the intersection of the marginal revenue product curve and the factor supply curve. This is, by no coincidence, the perfectly competitive, efficient, outcome. And none of this is coincidence because $10 minimum wage is designed to generate that particular outcome.
How does this minimum wage outcome compare with the monopsony outcome? The wage rate is obviously greater ($10 compared to $8.40). However, employment is ALSO greater (50,000 workers compared to 37,000 workers). And there is NO unemployment? The minimum wage did not created unemployment. In fact, MORE workers are employed and
they ALL receive a higher wage. It is a win-win situation for ALL workers in the market.

5.3 Bilateral Monopoly
A market containing a single buyer and a single seller, or the combination of a monopoly market and a monopsony market. A market dominated by a profit-maximizing monopoly tends to charge a higher price. A market dominated by a profit-maximizing monopsony tends to pay a lower price. When combined into a bilateral monopoly, the buyer and seller both cannot maximize profit simultaneously and are forced to negotiate a price and quantity. Then resulting price could be anywhere between the higher monopoly price and the lower monopsony price. Where the price ends ups depends on the relative negotiating power of each side.
Begin 2 Market 4 Shifts 5 M & M3 Adjustment 6 Labor End40
5.3a Bilateral Monopoly: Example
Industrial Labor: a number of modern labor markets contain a dominate employer on the buying side and a dominate labor union on the selling side. Negotiations between large corporations and labor unions over wages and working conditions, such as those between General Motors and the United Autoworkers Union, approximate the bilateral monopoly model. While these markets are not, strictly speaking, comprised of pure monopoly sellers and pure monopsony buyers, the do have a definite bilateral monopoly flavor.

5.3b Bilateral monopoly labor market: TV Screen Writers
Consider the current (Nov 2007) Screen writers srtike On the buying side are the Hollywood producers represented by the Alliance of Motion Picture and Television Producers.. Assuming that everyone who writes TV scripts either works for the Alliance or they do not work at all, then this makes the Alliance a monopsony buyer.On the selling side are the screen writers represented by the Writers Guild of America Assuming The Guild speaks for ALL of the screen writers, then it essentially is controlling the supply-side of this particular labor market. This makes the Guild a monopoly seller.YouTube Video, Supporter

5.3c Bilateral monopoly labor market: TV Screen Writers
What results from this bilateral monopoly is the need for negotiation between the monopoly (Writers Guild) and the monopsony (TV Producers). Without the Writers Guild monopoly on the selling side, the Alliance of TV Producers monopsony maximizes profit by paying 37,000 workers a wage of $8.40 per hour. Without the Alliance of TV Producers monopsony on the buying side, the Writers Guild monopoly maximizes profit (that is, member income) by charging a wage of $15 per hour to employ 30,000 workers. The two sides need to negotiate a price. But what price? Unlike other output analyses, there is no way of knowing the price. It could be $8.40, it could be $15, or (more likely) it could be anywhere between. Where the price ends up depends on the relative negotiation power of each side. If the TV Producers are extremely powerful, with oodles of profit, with tons of inventory available, or with an extremely talented team of negotiators, then the price might end up close to $8.40. However, if the Writers Guild has charismatic negotiators, has unwavering support from every employee, and has a large bank account, then the price might end up close to $15.There is no way of knowing in advance.

6.1b Work and Utility
Work is not a pure source of utility, rather it is a source of disutility the opposite of utility
Net utility of work -- the utility of consumption made possible through work minus the disutility of the work itself; usually makes some amount of work an attractive use of part of an individual’s time
In the case of market work, the individual’s income buys goods and services
Begin 2 Market 4 Shifts 5 M & M3 Adjustment 6 Labor End46
6.1c Utility Maximization
Within the limits of a 24-hour day, seven days a week, individuals can balance their time among market work, nonmarket work, and leisure in order to maximize utility
The rational consumer will attempt to maximize utility by allocating time so the expected utility of the last unit of time spent in each activity is identical

6.3 Backward Bending Labor Supply Curve
The individual supply curve slopes upward until a wage of $12 is reached: at $12, the substitution effect dominates – the quantity of labor supplied increasesAfter a wage of $12, the labor supply curve bends backward and the income effect dominates – the quantity of labor supplied decreases

6.4 Market Labor Supply CurveThe labor supply curves of different individuals do not bend backwards at the same time – here we have three individual supply curves that sum to a market supply curve that slopes upward over the realistic range of wages

6.5b Wages Differentials by Education
Training, Education, Age, and ExperienceSome jobs pay more because they require a
long and costly training periodFewer individuals are willing to incur the time
and expense requiredResults in a smaller market supply
However, extensive training increases the productivity of labor There is increased demand for these skills

6.5d Application of AE Profiles
In wrongful death lawsuits, the plaintiff economist uses data on salary by occupation to estimate the total earnings of the decedent over the remainder of their work-life expectancy. (An estimate of the number of years an individual would have participated in the labor force.)

6.5e Application
Total earnings can be estimated in two waysFirst Method: Obtain recent earnings.: Recent
Year Earnings2000 $ 34,0002001 $ 34,5002002 $ 35,7002003 $ 38,1002004 $ 42,000
Then project forward based on the average increase in those wages :. The Geometric Mean is one easy formula for average annual increase:
($42,000/$34,000)^(1/4) = 1.0542 5.42%General Formula for Geometric Mean: (Et/E1)(1/t-1)

6.5f Potential Problem with First Method
Some individuals may be on that portion of age-earnings profile where earnings are either increasing rapidly or starting to decreaseThus for young decedents with a long remaining work-life the appropriate method is to consult age-earnings profile to obtain earnings growth for each educational attainment, and for each stage of the age intervalProf. Jacob Mincer (Columbia University) was the first to quantify the age earning profile for return to education Copyright © 2003 by Pearson Education, Inc. 6-36

Some Age Earnings Factors
An example of Age Earnings Adjustment factors
is in the exhibit
Source: “An Empirical Evaluation of Different Methods for Estimating Earnings Losses,” with J. Lambrinos, The Journal of Risk and Insurance, Vol. 56, No. 4, December 1989, 733-739.
The exhibit illustrates that for each educational attainment level picking the factor of the lowest age group will give an upward bias to the estimate of the total earnings.
Using the factor for each age interval will be more accurate.

Example: Carbon Based Fuel TaxAn energy policy that taxes carbon based fuel
Congress is considering several measures that would impose a so-called cap-and-trade system, which would limit the amount of carbon dioxide companies are allowed to emit.
Changes the relative price of nuclear powera cap-and-trade system would probably push up wholesale electricity prices in deregulated markets, as coal- and natural-gas-burning utilities jack up prices to recover the additional cost of allowance purchases. Nuclear operators stand to gain from greenhouse-gas legislation in two ways. For starters, their plants don't spew carbon dioxide, so they would not have to buy emissions allowances, giving them a competitive advantage over competitors that burn fossil fuels.

Example: Monopoly Pricing At a time when food prices are soaring world-wide, so is the price of fertilizer, producing huge profits for leading fertilizer makers and stirring anger among farmers in the U.S. and India.Fertilizer prices are rising faster than those of almost any other raw material used by farmers. In April, farmers paid 65% more for fertilizer than they did a year earlier, according to the U.S. Department of Agriculture. That compares with price increases of 43% for fuel, 30% for seeds and 3.8% for chemicals such as weedkillers and insecticides over the same period, according to Agriculture Department indexes.Those skyrocketing costs are making it harder for farmers to expand their harvests in response to the global food crisis that has sparked rioting, rationing and export controls in many countries. Food prices have soared in recent months as the world's growing demand for grain, which has exceeded production for much of this decade, has reduced stockpiles to extremely low levels. Farmers say too much market power is concentrated in the hands of a small group of companies in the U.S., Canada and Russia that dominate global production of potash and phosphate. In an interview Monday, Mr. Doyle called recent complaints about prices an emotional reaction. Fertilizer prices began rising in earnest about a year ago after a nearly decadelong period of stability. "People don't like higher prices," Mr. Doyle said. But "you never hear from anyone complaining when prices are low.“
He added during the call that continued price rises will "be a shock" to some consumers.
In the U.S., Potash Corp. and Mosaic are the sole surviving members of a phosphate export cartel called the Phosphate Chemicals Association. Under a 90-year-old law designed to promote American exports, the companies are allowed to legally market and sell their product overseas as a single entity at a price set in consultation with one another. Similarly, Canada has Canpotex, and Russia has Belarus Potash Co., another export cartel.
While the individual cartels can't legally collaborate among themselves on pricing, they regularly -- and legally -- follow each others' price increases. After the Russian cartel recently said potash prices would rise to $1,000 a ton, Potash Corp.'s Mr. Doyle said Canpotex would soon match that price.Denis Evstratenko, a UBS metals and mining analyst, said the cartels have little incentive to undercut one another in the current environment.
To protect American consumers, members of the U.S. cartel are required by law to compete against each other in selling their wares at home. But in today's global markets, the global price sets a benchmark so American farmers pay essentially what the cartels dictate.Source

Example Boeing and Recession
Mr. Stewart is one of 27,000 Boeing machinists who voted to walk out on Sept. 6, when both Boeing and the world were in a much different place. Boeing had a bulging order book and was straining to meet production goals. The economy was sagging under the housing crisis, but had not yet buckled.Since then, instability in the financial sector has pushed the U.S. into what many believe could be a recession. The labor standoff in the midst of the financial turmoil may seem like lunacy to outsiders, but not to Mr. Stewart. Many striking workers say the broader economic gloom is only fueling their determination to lock in job security now. The machinists, who earned an average of $65,000 a year with overtime, are supplementing their $150-a-week strike pay with part-time jobs. The union complains that its members have already lost too much work because of Boeing's outsourcing. The company says it won't make guarantees about job security that could wind up hurting its competitiveness down the road. American labor can point to few victories recently. Sectors like textiles and auto manufacturing have watched jobs move overseas or into nonunion plants. Last year, the United Auto Workers made key concessions on pension issues, in part because of concerns about the financial health of big U.S. auto makers.But machinists at Boeing have clout that few other American workers can match. The plane maker, which has its headquarters in Chicago, has only one chief competitor, European Aeronautic Defence & Space Co.'s Airbus, and its products are so sophisticated that they have yet to come under pressure from low-cost countries in Asia.Source: Boeing Strikers Dig In Heels Even as Economy Turns Sour By J.
