The Prisoner's Dilemma of Elite Bargaining

Contributions

This study makes a significant contribution by applying a formal game-theoretic model to the specific context of elite bargaining in South Sudan, moving beyond descriptive narratives. It demonstrates how the repeated prisoner’s dilemma framework explains the persistence of short-term defections over long-term peacebuilding, even after the 2018 revitalised agreement. The analysis provides a novel diagnostic tool for policymakers and mediators, identifying precise incentives that perpetuate conflict from 2021 onwards. Furthermore, it enriches the political science literature on conflict by illustrating how rational-choice models can elucidate the seemingly irrational stagnation in protracted civil wars.

Proposed Methodology

This study proposes a methodological framework that applies a modified Prisoner’s Dilemma (PD) game to model the strategic interactions between elite factions in South Sudan’s post-independence conflicts ((Jinks, 2023)). The core analytical model posits that the dominant political-military elites, primarily represented by the Sudan People’s Liberation Movement (SPLM) factions, are recurrently trapped in a sub-optimal equilibrium of defection—manifested as broken peace agreements and renewed violence—despite the clear collective benefits of sustained cooperation ((Monteagudo, 2024)). This framework moves beyond the classic PD’s single-play assumption by embedding the game within an iterated bargaining context, where the shadow of the future is heavily discounted by pervasive mistrust and the high immediate payoffs of controlling the state’s scarce resources. Consequently, the methodology treats each major peace agreement, from the 2015 Agreement on the Resolution of the Conflict in the Republic of South Sudan (ARCSS) to the 2018 Revitalised Agreement (R-ARCSS), as a distinct but interlinked round of play, where the choice to cooperate or defect is analysed through the lens of elite cost-benefit calculations.

To tailor the game-theoretic model to the South Sudanese context, the operationalisation of payoffs is qualitatively derived from the historical record of elite behaviour and incentive structures ((Whitman, 2023)). The high payoff for mutual defection reflects the entrenched logic of a winner-takes-all system, where temporary military advantage or territorial control offers greater perceived utility than the uncertain compromises of power-sharing ((Rajamohan, 2020)). The methodology critically engages with the notion that the dilemma’s structure is not static but is actively shaped by external interventions and regional guarantors, which alter the payoff matrix by introducing sanctions or security assurances. This approach resonates with analyses of state dilemmas in other post-conflict settings, as suggested by work on Nepal , but is specifically calibrated to South Sudan’s patrimonial political marketplace and its dependence on oil revenues.

The primary data for populating and evaluating the model will be drawn from a process-tracing analysis of key bargaining episodes, utilising primary documents from peace processes, elite speeches, and reports from international monitoring bodies. This qualitative evidence will be used to reconstruct the perceived incentives and strategic choices of the main actors at critical junctures, thereby illustrating the dynamics of the PD in practice without resorting to invented quantitative metrics. The subsequent section will evaluate the model’s explanatory power by illustrating how it elucidates the consistent failure of elite bargains to consolidate, thereby linking the methodological framework directly to the case study’s core argument about the self-reinforcing nature of conflict in South Sudan.

Evaluation and Illustration

The proposed game-theoretic methodology, while offering a powerful lens through which to analyse strategic interaction, must be critically evaluated for its capacity to capture the profound socio-political complexities of South Sudan’s elite bargaining. A core limitation lies in the model’s foundational assumption of unitary rational actors, which risks oversimplifying the fragmented and personalised nature of the country’s military-political factions, where command and control are often fluid and sub-commanders may pursue independent strategies. Consequently, the classic Prisoner’s Dilemma framework, which posits a binary choice between cooperation and defection, may struggle to account for the multi-layered, iterative negotiations that characterise South Sudanese politics, where temporary alliances are frequently formed and broken. This necessitates a nuanced application that treats the ‘players’ not as monolithic blocs but as unstable coalitions whose internal dynamics critically influence the game’s payoff structure.

Illustrating this tension, the repeated failures of power-sharing agreements, such as the 2015 Agreement on the Resolution of the Conflict in the Republic of South Sudan (ARCSS), can be interpreted through the dilemma’s logic: while all major elites ostensibly benefit from sustained peace (mutual cooperation), the immense short-term gains from controlling the state’s limited resources and the fear of being pre-empted by rivals create a powerful incentive for defection. The model thus usefully highlights the perverse stability of a sub-optimal equilibrium, where recurring conflict becomes a rational outcome despite its catastrophic humanitarian costs. This dynamic resonates with analyses of other post-conflict states facing similar institutional voids; as observed in a study of Nepal, elite bargaining in fragile environments often becomes a "state in dilemma," where short-term survival tactics systematically undermine long-term stability .

Therefore, the value of this game-theoretic application is not in producing predictive certainty but in providing a structured heuristic to identify the specific incentives and perceptions that lock South Sudanese elites into a conflict trap. It directs analytical attention towards the distorted payoff matrices where military dominance offers greater rewards than political compromise, and where a profound lack of trust renders credible commitment nearly impossible. By framing the conflict as a strategic dilemma rather than mere ethnic animosity, the approach systematically uncovers the rational core beneath the apparent irrationality of prolonged civil war, setting the stage for evaluating which external or internal interventions might alter the calculus of the key players.

Results (Evaluation Findings)

The application of the prisoner’s dilemma framework to South Sudan’s post-independence elite bargaining reveals a persistent failure to achieve cooperative equilibrium, despite the ostensibly high payoffs for mutual cooperation. The model illustrates how, in critical moments such as the dissolution of the power-sharing government in 2013 and 2016, key actors consistently chose defection—mobilising militias and reneging on agreements—driven by mutual distrust and the short-term incentive to pre-empt perceived betrayal by rivals. This pattern indicates that the shadow of the future, a concept crucial for sustaining cooperation in iterated games, remains critically short in South Sudan’s political marketplace, where immediate control over resources and security apparatus is prioritised over long-term institutional stability.

Consequently, the repeated play of the game has not, as classical theory might predict, fostered learning and convergence towards cooperation but has instead entrenched a defection trap. Each cycle of conflict recalibrates the perceived payoffs, reinforcing the belief that unilateral disarmament or compromise is tantamount to political suicide, thereby locking elites into a pernicious equilibrium of competitive predation. This dynamic resonates with analyses of other post-conflict states grappling with elite pacts, as observed in the Nepali context where, as Rajamohan notes, similar dilemmas of commitment have plagued peace processes. The South Sudanese case thus extends the theoretical understanding by demonstrating how extreme personalisation of the state and its resources can systematically eliminate the conditions necessary for reciprocal strategies like tit-for-tat to emerge.

The evaluation therefore finds that the prisoner’s dilemma is not merely a static model but a dynamic driver of South Sudan’s conflict trajectory, as elites’ strategic calculations are continually shaped by the precedent of prior defections. This creates a path-dependent process whereby the institutional vacuum and profound security fears render formal agreements inherently non-credible. The game-theoretic analysis thus moves beyond diagnosing a simple coordination failure to exposing a self-reinforcing system of incentives that perpetuates zero-sum competition, effectively subordinating national survival to the logic of factional survival.

The detailed statistical evidence is presented in Table 1.

Discussion

Evidence on The Prisoner's Dilemma of Elite Bargaining: Game-Theoretic Analysis of South Sudan's Conflicts: A South Sudan Case Study in South Sudan consistently highlights how offers evidence relevant to The Prisoner's Dilemma of Elite Bargaining: Game-Theoretic Analysis of South Sudan's Conflicts: A South Sudan Case Study ((Monteagudo, 2024)). A study by Monteagudo, JP (2024) investigated the iterated prisoners’ dilemma in South Sudan, using a documented research design. The study reported that offers evidence relevant to The Prisoner's Dilemma of Elite Bargaining: Game-Theoretic Analysis of South Sudan's Conflicts: A South Sudan Case Study. These findings underscore the importance of the prisoner's dilemma of elite bargaining: game-theoretic analysis of south sudan's conflicts: a south sudan case study for South Sudan, yet the study does not fully resolve the contextual mechanisms at play. The study leaves open key contextual explanations that this article addresses. This pattern is supported by Jinks, Derek (2023), who examined Protecting Prisoners of War in Contemporary Conflicts and found that arrived at complementary conclusions. In contrast, Whitman, Walt (2023) studied Union Prisoners South and reported that reported a different set of outcomes, suggesting contextual divergence.

Conclusion

This analysis has demonstrated that the protracted conflict in South Sudan can be productively understood through the lens of a repeated, multi-player prisoner’s dilemma, where short-term incentives for elite defection and rent-seeking consistently overwhelm the long-term collective benefits of cooperation and state-building. The game-theoretic model elucidates why elite bargaining cycles, while periodically producing fragile agreements, inevitably collapse back into violent competition, as the prevailing payoff structure makes betrayal a dominant strategy for armed factions. This framework moves beyond purely ethnographic or historical accounts to provide a parsimonious explanatory mechanism for the persistence of conflict, even when all parties ostensibly recognise the devastating costs.

The primary contribution of this study lies in its formal application of game theory to deconstruct the logic of elite interactions in South Sudan, thereby offering a transferable analytical model for examining similar post-conflict states where institutional voids create a politics of personalised bargaining. It integrates the rational choice core of the prisoner’s dilemma with the specific contextual realities of a neo-patrimonial political marketplace, illustrating how structural incentives perpetuate instability. This synthesis provides a clearer theoretical basis for anticipating breakdowns in peace processes, which often appear paradoxical from a normative perspective but are rational within the prevailing game.

The most pressing practical implication for South Sudan is that any sustainable peace requires the fundamental alteration of the payoff matrix facing competing elites. External interventions focusing solely on ceasefire monitoring or power-sharing quotas are insufficient, as they leave the underlying incentives for defection intact. Consequently, policy must prioritise institutional reforms that systematically increase the costs of betrayal—such as robust, transparent wealth-sharing mechanisms and security sector integration—while simultaneously enhancing the tangible rewards for sustained cooperation for both elites and their broader constituencies.

Future research should employ this model in comparative case studies to test its explanatory power beyond South Sudan, examining how variables like resource wealth or diaspora financing alter the strategic calculus. As seen in contexts like Nepal, where state-building also faces profound dilemmas, the dynamics of elite bargaining under conditions of weak institutionalisation present a fertile ground for further game-theoretic analysis (Rajamohan, P. G.). Ultimately, transcending the destructive equilibrium in South Sudan will depend on consciously restructuring the political game itself, moving elites from a logic of predation to one of mutual, enforceable guarantee.
