UMNO’s recent successes at the state elections have stirred anxiety in Perikatan Nasional (PN). Despite initially working together to cease control from Pakatan Harapan (PH)
The Beginning of PN’s Quagmire
Rumours are ripe in Malaysia that the 15th General Election (GE15) would be held by the end of 2022 despite Parliament’s mandate to do so by September 2023. Among the reasons for this call for election is the failed bid by ex-premier Najib Razak to overturn his 2020 conviction for abuse of power, criminal breach of trust and money laundering. With other UMNO leaders such as Zahid Hamidi and Bung Mokhtar facing court case
As UMNO tries to reclaim its supposed traditional hold on power, PN has found itself in a quagmire of their own doing. This difficult position faced by PN is akin to the classic prisoner’s dilemma.
Prisoner’s dilemma is a common example within game theory that demonstrates why two perfectly rational individuals might not cooperate, even if it appears to be in their best interests. Since betraying a partner yields greater reward than cooperating with them (on condition the partner keeps silent), all purely rational self-interested prisoners will betray the other.
In the 2020 Sheraton Move, it could be deduced that those who defected from PH were acting rationally as their payoff was greater relative to those who were left behind in the then-ruling coalition. Those who left the PH government were rewarded with opportunities to be a part of the government that succeeded PH. This was made possible with the backing of UMNO and BN. PH, for choosing to stick to its principle, was quickly relegated to its former position as the opposition within government. Anwar Ibrahim, leader of PH, claimed to know of support by 15 UMNO members for him to become prime minister as revealed by former UMNO Supreme Member, Tajuddin Abdul Ra
Irrational for both PN and PH to Cooperate
There are a few versions of the prisoner’s dilemma and one of them is the iterated variant. In a repeated game, players may be less eager to cooperate if their counterpart has not cooperated, resulting in dissatisfaction and a worse outcome.
This has impeded PN from cooperating with PH in the next general election. After the recent state elections, PN has sought to again work together with PH in the name of securing the country from fallin
What Muhyiddin Yassin, PN chairman, was seeking is the best possible outcome of the prisoner’s dilemma when both prisoners within the game cooperate by keeping silent instead of confessing to their crime. In prisoner’s dilemma, the best outcome for both prisoners would be to not admit to the crime, but if one of them defects, the defector would be set free while the other prisoner would serve a longer jail sentence. Without knowing what the other person would do, the rational choice is always to defect. The dilemma is that if both defect, they would be worse off than if they had cooperated. But for both players to cooperate successfully, they need to hedge on their partner keeping to their end of the agreement. This is where their past defection will come to haunt them. A rational player such as PH, taking past precedence into consideration, is less incentivised to trust Muhyiddin Yassin and PN. It would be noble of PH to trust PN but irrational. Therefore, based on game theory, Rafizi Ramli of PKR is right not to accept PN or even Mahathir’s newly formed Gerakan Tanah Air (GTA) as partners in the next election. It may also be irrational for PH to cooperate with MUDA despite the latter being ready to do so. This is considering the newly established youth party’s refusal to be an official component of PH. Without such commitment, the possibility for the party to defect from this cooperation could be too much for PH to stomach.
Further preventing such cooperation is the refusal of several members of the PN coalition to cooperate with PH. PAS, for example, has clearly stated its refusal to work with PH. To prevent the risk of these members exiting PN, any calls for cooperation with PH is all but dead. Despite both PN and PH likely to be at the losing end in t
Beyond Game Theory?
Of course, political coalitions are not merely based on game theory. Political players are, after all, more than numbers and formula. Though unlikely, PH may be swayed by Duverger’s law going into GE15. According to this law, a plural electoral system would most likely produce a two-party system. If votes continue to be split three-ways, there would be a lot of wasted votes and those elected into power may not represent the majority. Based on previous state elections, the winner would most likely be BN in GE15. Questions remain as to 1) whether the possibility of such an outcome compel both PN and PH to irrationally cooperate, and 2) how stable would such cooperation be?
