Abstract

Why do some autocrats establish a ruling party, whereas others do not? The existing literature argues that weak leaders facing a commitment problem have an incentive to create highly institutionalised parties in order to stabilise their ruling coalition. However, empirical research points out that stronger leaders also create ruling parties, which tend to lack institutional strength and be short-lived.

Through a simple formal model and a case study, this paper explains strong leaders’ motivation to create less-institutionalised, short-lived parties. My model introduces two variables to classical leader-elite bargaining model. (1) indivisible benefit from incumbency, which the leaders can exclusively consume and cannot share with ruling elites. This makes the bargaining more difficult while it also increases the leaders’ merit to maintain his post. Thus, the leaders found ruling parties to temporarily deter the elites’ defection, even if the leaders are sure that their ruling coalition will inevitably collapse in the near future. (2) loser’s share, which the elites consume even after the failed rebellion. Many existing models assume that losers in rebellions lose everything, but some leaders lack the willingness or capability to punish defectors. The low loser’s share decreases the elites’ future share, which encourages weak elites to rebel before their bargaining power furthermore goes down. Thus, even strong leaders can face the commitment problem. Through the case study of Georgia, this paper also shows that even less-institutionalised ruling parties can prevent elites from rebelling by empowering potential defectors.

Figure 1. Personalisation of authoritarian ruling parties. The vertical axis shows the proportion of authoritarian ruling parties with various levels of personalisation. I code parties that have more than 50% of seats in national legislatures in non-democratic countries as ‘authoritarian ruling parties’. The number of seats each party has is based on the V-Party dataset (Lührmann et al., 2020). The regime classification relies on the Autocratic Regimes dataset (Geddes et al., 2014). The level of party personalisation is based on the four-degree assessment of the V-Party. (Lührmann et al., 2020): 0: The party is not focused on the personal will and priorities of one individual leader. 1: The party is occasionally focused on the personal will and priorities of one individual party leader. 2: The party is somewhat focused on the personal will and priorities of one individual party leader. 3: The party is mainly focused on the personal will and priorities of one individual party leader. 4: The party is solely focused on the personal will and priorities of one individual party leader.

Figure 2. Candidate nomination of authoritarian ruling parties. The vertical axis shows the proportion of authoritarian ruling parties with various levels of personalisation. I coded as ‘authoritarian ruling parties’ ones that have more than 50% of seats in national legislature in non-democratic countries. The number of seats each party has is based on the V-Party dataset (Lührmann et al., 2020). The regime classification relies on the Autocratic Regimes dataset (Geddes et al., 2014). The level of party personalisation is based on the four-degree assessment of the V-Party. (Lührmann et al., 2020): 0: The party leader unilaterally decides on which candidates will run for the party in national legislative elections. 1: The national party leadership (i.e., an executive committee) collectively decides which candidates will run for the party in national legislative elections. 2: Delegates of local/regional organisations decide which candidates will run for the party in national legislative elections. 3: All party members decide on which candidates will run for the party in national legislative elections in primaries/caucuses. 4: All registered voters decide on which candidates will run for the party in national legislative elections in primaries/caucuses. No authoritarian ruling party has Score 4.

The arrows represent the change of the thresholds when the loser’s share increases. (b) When the loser is small, ${k^l}\left( {{p_t}} \right)$. The arrows represent the change of the thresholds when the loser’s share decreases.
