Investment Incentives and Merger-Specific Efficiencies
The efficiencies potentially available from a merger may
be an important factor both in the companies’ decision to
merge and in the antitrust authorities’ decision whether to
challenge the transaction. Efficiency gains will reduce
costs and hence increase profits. Whether these gains will
also reduce price and increase consumer welfare is another
matter. In evaluating merger efficiencies, the antitrust
authorities should recognize that improvements in investment
incentives may be important efficiencies that increase
consumer welfare.
This interest in consumer welfare has led the antitrust
authorities to focus on efficiencies that reduce marginal
costs. Reductions in fixed cost can also encourage
investment and thus increase output and consumer welfare.
Such efficiencies gains are likely to be cognizable under
the revised Merger Guidelines. The Guidelines state that
“certain types of efficiencies are more likely to be
cognizable and substantial than others. For example,
efficiencies resulting from shifting production among
facilities formerly owned separately, which enable the
merging firms to reduce the marginal cost of production, are
more likely to be susceptible to verification,
merger-specific, and substantial, or may be cognizable for
other reasons.” If a merger enables an expansion of capacity
at one of the merged firm’s facilities, that will enable
production to be shifted to that facility. Such a shift in
production may result in savings that are readily cognizable
according to the Merger Guidelines.
The oil refining industry requires substantial fixed
investments to increase capacity, and two merging oil
refineries in Korea claimed increased investments would
result in substantial efficiency gains. This claim was
assessed using a game-theoretic model that specifically
recognized the sequential nature of merger and investment
decisions. The model was used to analyze the investment
decisions likely to be made by market participants and then
evaluate the total fixed cost for the market and the
marginal cost for each firm both with and without the
merger.
This modeling approach was applied to evaluate the
merger-specific efficiencies from a proposed merger between
the largest refinery in Korea, SK Corporation (SK), and the
smallest refinery in Korea, Inchon Oil (ICO). This merger
was subject to review by the Korea Fair Trade Commission
(KFTC), which is often said to judge merger efficiencies
using standards that are comparable to those used by the
U.S. authorities. SK planned to make substantial investments
in ICO if the merger were allowed. Efficiencies resulting
from these investments would be cognizable only if these
investments would not take place without the merger.
Therefore, a critical examination of efficiency claims
should address the following questions:
• Would an alternative buyer invest in ICO in a way
that would be similar to the planned investments by SK?
• Would SK make similar investments in other facilities
were it unable to acquire ICO?
Alternative buyers would likely not have made the
same investment in ICO that SK planned. The most likely
alternative buyer for ICO’s assets was a consortium of
foreign investors. Those investors would make necessary
investments to continue ICO’s operations, but had no
incentives to make a long-term strategic investment to
improve ICO’s refining capability or efficiency. The other
possible alternative purchasers were the other oil
refineries in Korea: GS Caltex, Hyundai Oilbank, and S-Oil;
however, they expressed no interest in acquiring ICO. Any
potential buyer except SK would have been reluctant to
invest in ICO because there was already an overall excess
capacity in oil refining for the Korean market. Compared to
the other Korean refineries, SK had the largest network of
foreign buyers and already had a presence in China selling
refined products. SK projected that China’s demand for
refined products would far outstrip Chinese domestic
refining capacity. Thus, SK had greater incentives to invest
in refining capacity in order to export to China as well as
meet the domestic demand in Korea. Furthermore, in
comparison with other potential buyers, SK’s extensive
experience acquired in the process of improving and updating
its own refineries would be readily transferable to improve
ICO’s refineries.
Suppose SK was unable to acquire ICO. It is then unlikely
that SK would have expanded refining capacity in its
existing facilities. To increase its capacity, it must
expand its existing facilities by acquiring adjacent real
estate, and acquiring the necessary neighboring real estate
was deemed to be prohibitively expensive. So, had SK
invested in its own facilities, much of the investment would
have gone to acquiring real estate, and the increase in
productive capacity would have been much less than would
have resulted from the same level of investment in the ICO
facilities. Therefore, acquiring ICO would allow a more
profitable investment for SK than investing in its own
facilities.
Besides the increase in capacity, other efficiencies
would also result from SK’s acquisition of ICO. SK could use
its superior technical know-how to greatly enhance ICO’s
productive efficiency. Moreover, the use of SK’s network for
ICO products would reduce the cost of importing crude oil
and exporting refined products. A substantial portion of
these efficiencies would be marginal cost reductions that
would be readily passed on to the Korean consumers.
In assessing the effects of a merger, it may be important
to ask how the merger will affect investment incentives and
the growth of industry capacity. A game-theoretic analysis
of the SK’s acquisition of ICO finds that the merger would
put the acquired firm’s assets in the hands of a company
with greater ability and incentives to expand productive
capacity than any other potential buyer, thereby generating
cognizable efficiency gains. These efficiencies would likely
reduce prices and increase consumer welfare. Largely because
of these cognizable efficiencies and competitive constraints
from the world oil market, the KFTC did not challenge the
merger.
