FORMING A GOVERNMENT
Readings: Lijphart pgs 90-115 and 135-139 and Laver and Schofield
Guiding Questions
What is coalition theory? How do we explain which parties get into
government? What do office based theories hypothesize? What do policy based theories hypothesize?
Coalition Theory
In majoritarian systems, election day determines who forms government. Whoever gets the most votes, wins.
Many parliamentary systems use proportional representation to elect representatives. This makes it difficult for one party to win more than 50% of the seats. Parties wishing to enter government have to create a coalition that cannot
be defeated on a confidence vote. Coalition theory examines why certain parties enter government and others do not.
Following an election there are many possible coalitions. But not all are feasible. Some parties are always in government while others are always in
opposition. Why are certain parties more likely to enter government while others do
not seek to enter government at all? Literature offers both office based and policy based motivations for entering
government
Office Seeking Theories
Posit that parties primarily seek the spoils associated with holding office Conceives of government formation as a zero sum game over
the spoils of office Spoils include seats in cabinet, political appointments, agenda control, etc.
Theories are usually “policy blind” Parties only care about policy to the extent which it enhances their ability to
obtain office
Lijphart 1999 Several types of office seeking theories of coalition
formation Minimal winning Minimum winning (or minimum size) Bargaining proposition/minimal range Minimum connected winning (MCW)
Minimal Winning Coalitions
Riker 1962 If parties are primarily concerned about
gaining the spoils of office, then they will not want to enter a coalition that contains more parties than necessary to obtain a majority. Hypothesis: Minimal winning coalitions will
form. Minimal winning coalitions:
Coalitions where every party is critical to maintaining a majority (i.e. no superfluous parties).
Observations: From 1945-1987, 35% of coalitions formed followed this pattern.
Minimum Winning Coalitions
Riker 1962 But in large systems, several minimal winning coalitions
are possible. How do parties choose between minimal winning coalitions?
Proportionality typically governs the allotment of seats within the cabinet A party bringing 20% of the seats to the coalition will
receive approximately 20% of the seats within the cabinet Thus, parties seeking to enhance their influence should
seek to form coalitions with the narrowest majority possible in order to boost their bargaining weight. Hypothesis: Minimum winning coalitions will form.
Minimum winning coalitions: Coalitions consisting of parties with the smallest total weight.
Bargaining Proposition/Minimal Range
Questions of which minimal coalition would be chosen plagued these theories. Ideological placement enters into the discussion
But ideology is only used as a means to an end Leiserson 1970 Leaders seek to reduce the number of parties necessary to
achieve a majority (bargaining proposition) Hypothesis: Minimal winning coalitions should form
containing the smallest number of parties possible Reducing the ideological range between parties eases
bargaining and makes it easier to maintain a coalition (minimal range) That is, it is easier to make and keep promises with
ideological neighbors Hypothesis: Minimal range coalitions should form

1 minimum winning coalition (minimal winning with smallest weight): 31: PP/PA/SDF/WL

Minimal Connected Winning Coalitions
Axelrod 1970 Policy “compatibility” reduces the number of
viable coalitions and eases bargaining. Hypothesis: Minimal connected winning coalitions
will form. Minimal connected winning coalitions:
Minimal winning coalitions made up of parties which are ideological “neighbors”
Loss of one party leaves a coalition which is either: 1) no longer winning 2) no longer connected
Italy 1972
PCI 179 PSI 61 PSDI 29 PRI 15 DC 267 PLI 20 MSI 56
127 coalitions were possible. 3 were minimal connected winning (MCW):
PSI/PSDI/PRI/DC PSDI/PRI/DC/PLI DC/PLI/MSI.
Any coalition including the MSI or the PCI was not an option. Five coalitions formed before new elections were held.

Italy 1972-Revolving Coalitions 1st: DC minority
government (267). 2nd: DC coalition
(minimum winning-316).
3rd: DC coalition (minimal connected winning-372).
4th: DC coalition (surplus majority-357 seats)
5th: DC minority government (282).
Evaluating Office Based Theories Pure office based theories cannot
address: 1) Why surplus parties are ever included in
a governing coalition? Example: Italy
2) Why minority governments form? Example: Denmark
But policy based theories of coalition formation can explain both
Policy Seeking Theories
Posit that political parties actually care about policy outcomes Although they are agnostic about whether or not this push for
policy is sincere (i.e. parties care about policy outcomes) or strategic (i.e. adopting certain policies are likely to aid in re-election).
Laver and Schofield 1998 Parties enter winning coalitions that will adopt their preferred policy.
That is, they seek to enter policy viable cabinets. Policy viable cabinets contain (or are supported by) the “core” or
“pivot” party Party controlling the median voter serves as the “pivot” within the
legislature. Why? Because no “winning coalition” can form to enact policy
against their wishes Sees the party holding the median voter as a “policy dictator”
Hypothesis: Coalitions will include the party holding the median legislator.
Denmark 1966
179 SEATS TOTAL. 8 OTHERS. MAJ = 90
The median legislator is a Social Democrat (SD). Any viable coalition would require SD support.
Result: SD formed a minority government. Defeating the SD would require parties of the left and
the right to coalesce. Unlikely. So a party could govern without holding a
majority of seats.

Evaluating Policy Based Theories Median parties are well placed in coalition
bargaining talks. More than 80% of coalitions from 1945-
1987 included or were supported by the median party.
To suggest that parties care about policy does not mean that they do not possess office seeking goals. Understanding government formation
requires us to look at BOTH policy and office goals. Some circumstances require parties to
emphasize one or the other.
Election 2005: Merkel’s Dilemma Majority = 308 No party could govern
alone. Schroeder and Merkel
both made claims on the chancellorship.
Merkel was given first crack at forming a coalition. Her party held the most
seats.
Election 2005: Merkel’s Dilemma Merkel’s preferred policy
coalition (yellow-black): FDP/CDU/CSU = 287
seats 21 short.
Schroeder’s preferred policy coalition (red-green): SPD/B90GR = 273
35 short. PDS/Left was not an
option. Both sides needed to woo
another party. Attention turned to the
B90Gr and FDP.
Election 2005: Merkel’s Dilemma From an office seeking
standpoint, adding B90/Gr (i.e. a “Jamaica coalition”) would give Merkel 338 seats. Rejected by the Green
party on policy grounds. Adding the FDP to the
SPD/B90/Gr (i.e. traffic light coalition) would give Schroeder 334 seats. But this was rejected by
the FDP on policy grounds.
Election 2005: Merkel’s Dilemma
Polls showed Germans did not want another election.
Merkel agrees to form a grand coalition with the SPD.
Coalition was strained by: 1) conservative social
policy advocated by the CSU
2) center left economic policy favored by the SPD
3) desire for economic reform by members of the CDU.
SPD entered 2009 elections pushing for a return of the grand coalition. CDU wanted to end it.
Conclusions: Election 2009
CDU vote declined slightlyBeing in government can sometimes come at an electoral cost.
Voters punished the SPDWorst performance in the postwar era
Voters rewarded the FDP, the Greens, and the LeftAll opposition parties fared well.
Government formed by the CDU/CSU and the FDP.Merkel was seeking a yellow-black coalition rather than another grand coalition
