Risk and transaction costs often provide competing explanations of institutional outcomes. In this article we argue that they offer opposing predictions regarding the assignment of fixed and variable taxes in a multi-tiered governmental structure. Although the central government can pool regional risks from variable taxes, local governments can measure variable tax bases more accurately. Evidence on tax assignment from the mid-sixteenth-century Ottoman Empire supports the transaction cost explanation, suggesting that risk matters less because insurance can be obtained in a variety of ways.
