How Do Minority Presidents Manage Multiparty Coalitions?

This is a blog post by Svitlana Chernykh based on her recent article with Paul Chaisty published in Political Research Quarterly (Online First). The full article can be found here.

Although the concept of coalitional presidentialism is not new, until recently, the question of how presidents form and manage their coalitions has been explored primarily in the context of Latin American presidential democracies. However, we know little about how and whether these theories travel outside Latin America. In “How Do Minority Presidents Manage Multiparty Coalitions? Identifying and Analyzing the Payoffs to Coalition Parties in Presidential Systems” we use original quantitative and qualitative data to analyse how minority presidents manage their multiparty coalitions to achieve legislative support in Ukraine.

Why Ukraine? With few exceptions, the country has been governed by multiparty cabinet coalitions since 1996 and thus offers rich macro-level data. Ukraine is also a difficult case with which to test institutional hypotheses. Many scholars of Ukrainian politics have questioned the applicability of notions of coalitional behavior to the country and have suggested that coalitional solutions to the problems of limited legislative support are difficult to operate in the Ukrainian context. Finally, presidential coalitions in Ukraine frequently contain cabinet parties as well as parties that do not have cabinet representation. This allowed us to explore the non-cabinet strategies that presidents used to manage the support of coalition parties.

Portfolio Allocation and Cabinet Coalition Discipline in Ukraine

In the first part of the paper, we test a now well-established hypothesis in Latin American literature that cabinet portfolio payoffs to coalition allies raise the level of legislative support for presidents. Our dependent variable is coalition discipline. It is measured as the percentage of legislators belonging to cabinet parties who voted in favour of bills introduced by the executive branch. Our main independent variable is the level of cabinet coalescence or the level of fairness in the distribution of cabinet posts among coalition members [1].

We find that cabinet coalescence has a positive and statistically significant effect on cabinet coalition discipline in Ukraine. To put it in substantive terms, an increase in cabinet coalescence by 10 percent increases cabinet coalition discipline by 2.4 percent. Thus, the dynamics of coalitional presidentialism in Ukraine are similar to those that we find in Latin America. The presidents who compose their cabinets more proportionally can expect a higher degree of satisfaction from allied parties and thus higher levels of discipline.

Managing Parties Outside of the Cabinet 

However, Ukrainian presidents also rely on the support of parties that do not receive portfolio payoffs. As the figure below shows, the number of non-cabinet coalition parties is significant in the Ukrainian case. In fact, the inclusion of non-cabinet parties was crucial in giving each president minimum winning majorities or near majorities.

How did the presidents in Ukraine secure their support? What were the motivations behind these parties’ decision to join the coalitions? To answer these questions, we interviewed 50 legislators, of whom 60 per cent were members of the coalition in 2012. We designed an interview sample and a number of structured and semi-structured questions to help us explore whether the perceived benefits of coalition membership differed significantly between members of coalition parties that had and did not have cabinet representation.

As figures 2 and 3 show, that the motivation to support the president differed between coalition parties that were members of the cabinet and those that were not. Non-cabinet coalition parties were significantly likely to identify extra-cabinet strategies such as patronage, budget payoffs, and informal favours when asked about strategies that the president used to form the coalition (figure2).

Figure 2. Percentage of non-cabinet and cabinet coalition party members who identified the importance of extra- cabinet benefits (patronage, budget resources, and informal favours) in the formation of coalitions.

We find a similar pattern when analysing the responses to a structural question, which asked legislators to choose the first and second most important reason why a political party would decide to join a presidential coalition from a list of options (figire 3). Members of the cabinet party were significantly more likely to identify policy influence and cabinet positions than the members of non-cabinet parties within the floor coalition. In contract, members of non-cabinet parties were more likely to mention budget influence and especially the informal exchange of favours than members of cabinet parties.

Therefore, on the one hand, the Ukraine case validates extant analysis on the effects of cabinet management on legislative behaviour. This suggests that coalitional presidentialism is not simply a unique Latin American phenomenon and gives us good reasons to expect similar dynamics in other regions of the world. Given the increasing preponderance of minority presidents in new democracies, this presents the opportunity to compare a diverse range of presidential cases across other parts of Europe as well as other regions including Africa and Asia.

On the other hand, the Ukrainian case also highlights the multivariate nature of the strategies that presidents deploy to maintain their legislative support. This adds a new dimension to the extant literature, which has mainly focused on the tools deployed by presidents at the cabinet level. By distinguishing between cabinet and floor coalitions, it is possible to identify parties that are motivated to join presidential coalitions by reasons other than cabinet portfolios. This finding highlights the need to consider the entire “toolbox” of resources that presidents can use to maintain their coalitional support [2].
