Coalition Governance under Separation of Powers: Shadowing by Committee in Coalitional Presidentialism

Abstract

Do coalition parties in presidential systems shadow one another with an eye on reducing agency loss? Our knowledge of intra-coalitional delegation under presidentialism remains limited to a few case studies. This article addresses that question using an original data set of committee chairs in eight multiparty presidential systems around the world. It shows that shadowing—the appointment of chairs from one coalition party to committees overseeing portfolios controlled by another coalition party—is a function of the degree of agency loss the coalition expects to a specific party, operationalized in terms of ideological distance as well as the salience of portfolios. However, the data also tentatively suggest that powerful committees reduce rather than increase the incidence of shadowing, which may be attributed to the risk of intraparty agency loss under separation of powers.
