Coalition Oversight Committees and Ministerial Drift
Quick fact
In many multiparty governments, coalition oversight committees—composed of senior members from each party—monitor ministers' policy proposals and can delay or block initiatives that deviate from the coalition agreement, effectively reducing ministerial drift.
Why this is interesting
Imagine a government where each minister is from a different party but must work together—how can they trust each other to stick to the deal?

Understanding Coalition Oversight Committees and Ministerial Drift
In a multiparty government, several parties share power, each heading different ministries. Since each minister wants to advance their own party's agenda, they may be tempted to steer policy away from the coalition agreement—this is ministerial drift. To prevent this, coalition partners often create oversight committees. These committees are made up of ministers and senior parliamentarians from each member party. Their job is to review policy proposals, budgets, and other decisions before they are implemented. If a proposal diverges from the coalition agreement, the committee can send it back for revision or even block it. This creates a system of checks and balances within the cabinet itself, ensuring that no single party can secretly pursue its own goals at the expense of the coalition's compromise.
A deeper explanation
The mechanism works through reducing information asymmetry. In a coalition, each minister has deep knowledge of their own policy area but limited knowledge of others. This asymmetry allows ministers to act opportunistically. Oversight committees address this by pooling information: members from different parties bring expertise from their own ministries, allowing the committee to cross-check policy drafts against the coalition agreement. Additionally, these committees create a credible threat of punishment. If a minister tries to drift, the committee can expose the deviation, which could lead to a political scandal or even the collapse of the coalition. The cost of being caught makes the threat of monitoring effective. Thus, oversight committees act as a commitment device: they make it more expensive for ministers to defect, thereby stabilizing the coalition. They are particularly important in governments where the coalition agreement is vague or where party preferences differ widely, because they replace vague promises with concrete verification and enforcement.
