IntroductIonAs a heuristic device, the principal-agent model's main contribution lies in its ability to offer tools to simplify complex realities relating to the reasons for and consequences of the delegation of powers to agents. At least, that is how the model has traditionally been introduced. However, theoretical parsimony has been bought at a relatively high theoretical and empirical cost. Although principal-agent models have been theorized for decades, the causal processes in between acts of delegation and agency discretion and autonomy are still not developed theoretically, with a large degree of opacity about how the model's elements are causally connected. 1 Instead, most uses of the principal-agent model focus on comparing input (preferences of principals and agents) with realized policy outcomes. However, by doing so, they black-box the actual process whereby agents potentially exploit their delegated powers for private gains. Yet just because there is a correlation between what agents want and achieved outcomes does not mean that delegation resulted in agency costs. When a principal does not complain about its agent, existing
