 41992 HORIZONTAL MERGER GUIDELINES a) 
Post-Merger HHI Below 1000. OK.  b) 
Post-Merger HHI Between 1000 and 1800. An 
increase in the HHI of less than 100 points is 
OK. A bigger increase needs analysis. c) 
Post-Merger HHI Above 1800. An increase in the 
HHI of less than 50 points is OK. An increase 
of more than 100 is presumed to be likely to 
create or enhance market power or facilitate its 
exercise, but the presumption may be 
overcome by showingthat competition would be 
vigorous anyway.  
 51992 HORIZONTAL MERGER GUIDELINES Two firms 
have market shares of 10 and 15, and all other 
firms are tiny. Can the two firms merge?  
- a) Post-Merger HHI Below 1000. OK.

firms in this industry have market shares of 5 
each. Can they merge?   b) Post-Merger HHI

of less than 100 points is OK. A bigger increase

 9Mittal-Arcelor (2007 merger) 
A global steel giant that will be almost 3 times 
bigger than the nearest rival, Nippon Steel 
 Parameters Unit Mittal Arcelor Capacity m 
MT 63.0 46.7 Revenues US bn 28.1 39.1 
US 32 bn takeover bid . 10 share of the global 
steel capacity of 1,132 m tonnes (MT) per year. 
(1997 world capacity 800, 2005 1132 MT The 
Mittal family will hold a 43.4, Arcelor 
shareholders will own 50.5 stake.  
 10 (1) As part of Mittal's bid an agreement 
to sell Dofasco , to ThyssenKrupp. Arcelor 
put Dofasco, its recently acquired Canadian 
subsidiary, into a Netherlands trust to keep 
Dofasco out of Mittal's grasp and make the whole 
acquisition of Arcelor more difficult. The 
United States government ordered Arcelor Mittal 
to sell Dofasco. If it cannot do that because of 
the trust structure, the company must divest 
either Mittals Sparrows Point mill near 
Baltimore or its mill in Weirton, W.Va. Also, 
Dofasco must operate like a stand-alone company. 
It cannot disclose any substantive information 
about operations to Arcelor Mittal the six 
directors the European company appointed to 
Dofasco no longer attend board meetings, which 
are now conducted by the Dofascos six 
independent directors and Arcelor Mittal only 
receives very limited information about the 
Canadian companys financial performance. (2) - 
Steel giant Arcelor Mittal said Friday thatit was 
selling its Polish steel mill Huta Bankowa to 
Alchemia SA as part of its compliance with EU 
antitrust . It had 81 million euros (104.7 
million) in turnover in 2005 and employs about 
700 workers.
  11Case 1 Merger Raises Price and Cost
-  Each of the two firms in the industry has TC 
 2  QQ/10, so MC  - Q/5 and FC 2. Each produces 10 units, so TC  
2 1010/10  12  - for each. Average cost is 1.2 and marginal cost 
is 2. The price is  - 3. 
 -  Industry profit is 320 - 22  1010/10  
 60 - 2 (12)  36.  -  After the merger, there is just one firm, with 
TC  2  QQ/10.  - Suppose it produces 15 units, which makes so 
the price goes up to 5.  -  TC  2  1515/10  2  225/10  24.5. Average 
cost is 24.5/15 1.6  -  and marginal cost is 15/53. 
 -  So total cost has risen, but output has fallen. 
 -  Industry profit is 515 - 24.5  75-24.5  
50.5. So the merger did  - raise profits, even though it reduced welfare.
 
  12Case 2 Merger Reduces Cost and Price
-  Each of the two firms in the industry has TC 
 2  3Q, so MC3  - and FC 2. Each produces 10 units, so TC  2  
310  32 for each  - firm. Average cost is 3.2 and marginal cost is 
3. The price is 4.  -  Industry profit is 420 - 2(2  310)  80 - 
232  16.  -  The merger allows the firms to share 
complementary technologies and reduce marginal 
cost. Therefore, after the merger, there is just 
one firm, with TC  2  .5Q.  -  The firm could reduce output from 20 to 15 and 
the price would rise  - to 5. Its profit would be 155 - 2  .5(15)  
75- 9.5  65.5.  -  But the firm prefers to increase output from 
20 to 30, which  - drives down the price to 3. Its profit is 303 
- 2  .5(30)  90 -  - 17  73.
 
  13Case 3 Merger Reduces Costs but Raises Price
-  Each of the two firms in the industry has TC 
 3Q, so MC3 and FC  - 0. Each produces 10 units, so TC  310  30 
for each firm.  - Average cost is 3 and marginal cost is 3. The 
price is 4.  -  Industry profit is 420 - 320  80-60  
20.  -  The merger allows the firms to share 
complementary technologies and  - reduce marginal cost. Therefore, after the 
merger, there is just one  - firm, with TC  2Q. 
 -  The firm could increase output from 20 to 
30, which drives down  - the price to 3. Its profit would be 303 - 302 
 90-60  30.  -  But the firm prefers to reduce output from 20 
to 15 so the price  - will rise to 5. Its profit would be 155 - 152 
  75 - 30 45.

  16Staples-Office Depot Merger (1997)
-  The FTC and Justice were notified 
(Hart-Scott-Rodino Act)  -  What is the concentration ratio? 
 -  Staples, Office Depot and Office Max clearly 
competed. Who else? What is the market?  
  17Price and Cost Effects 
- Assume no cost change. The FTC said the merger 
would raise prices 7.3. Staples said 2.4.  - What are cost savings? The FTC said 1.4 of 
sales, passed along to consumers. Staples said 
more, and being passed along was irrelevant.  - What is the ultimate price effect? The FTC said 
a 7.3 increase. Staples said a 2.2 decrease.  
  18An Efficient Merger? 
- Use the FTC numbers Costs fall by 1.4 of sales, 
prices rise by 7.3.  - Suppose the elasticity of demand is 1, which is 
average loosely speaking.  - Table 7.1 says a merger is OK if costs fall by 
.55 or more, prices rise by 10, and the 
elasticity is 1.  - Even if the elasticity is 2, if costs fall by 
1.21 or more, the merger is OK.  - But the FTC and the Court said the efficiency 
analysis wasnt going to decide the case.  -  
 
  19Evanston Northwestern Healthcare 
-  The FTC challenged the 2000 takeover of 
Highland Park Hospital by Evanston Northwestern 
Healthcare Corp., Northwestern U's nonprofit 
hospital.  - (1) FTC administrative law judge. 
 - (2) Any appeal of his ruling goes to the full 
five-member FTC  - (3) Further appeals by either side go to the 
federal appeals court.  -  In 2000 the hospital system raised United 
Healthcare's HMO rates by 52 at its Evanston and 
Glenbrook hospitals and by 38 at Highland Park.  - "Evanston Northwestern says it rescued the 
once-struggling community hospital in Highland 
Park and improved the quality of care. The 
hospital system has said that a forced 
divestiture, as demanded by the FTC, would 
"disrupt the lives of patients, doctors, 
employees" and others.""  -  In 2004, 130 hospitals were acquired or merged 
in the U.S. in transactions valued at a total of 
9.07 billion.  -  
 
  20Nonprofit Status 
-  In some previous mergers, courts have pointed to 
hospitals' nonprofit status as a reason to let 
mergers go through.  - In the mid-1990s the FTC fought unsuccessfully 
to block a Grand Rapids, Mich., merger. A federal 
court allowed it to proceed, based on economic 
analysis that nonprofit mergers tended to reduce 
costs and prices.  -  The court also ruled that nonprofit hospital 
boards, as community leaders, had an incentive to 
restrain prices. A federal appeals court upheld 
that ruling in 1997.  - Nonprofit hospitals, the FTC argues, do have an 
incentive to maintain a "surplus" of revenue over 
expenses, and while they don't distribute these 
"profits" to shareholders, they can use them for 
salaries, equipment or expansion.  - Evanston Northwestern 850 beds in three 
hospitals, about 7,600 employees and annual 
revenue of 1.8 billion. 239-bed Highland Park 
has 239 beds. 
  21Two Charges 
-  The FTC alleges it imposed big price increases 
on insurers such as Aetna Inc., Humana Inc. Cigna 
Corp., United Healthcare ... Several of the 
insurance companies, unhappy with the price 
increases, are expected to be called as witnesses 
by the FTC at the trial.  - In 2000 the hospital system raised United 
Healthcare's HMO rates by 52 at its Evanston 
and Glenbrook hospitals and by 38 at Highland 
Park.  -  The hospital raised its preferred-provider rates 
by 190 at Evanston and Glenbrook hospitals and 
by 20 at Highland Park.  - The FTC also has accused Evanston Northwestern of 
price-fixing of physician fees, after combining 
two large groups of physicians following the 
merger.  - The FTC is taking a highly unusual step in 
seeking to undo a merger.  - Dec. 2005 FTC wins with the administrative law 
judge.  - Feb. 2007 The case is currently on de novo 
review before the FTC on appeal from an 
Administrative Law Judge determination.
