This document discusses the development of serfdom in Russia from an institutional perspective. It presents a model showing how serfdom could arise as a social contract between the Tsar and landed gentry. This contract established serfdom as a labor monopsony that benefited both parties by increasing their profits at the expense of peasant surplus. The model indicates serfdom was more likely to emerge under conditions of abundant land, high agricultural prices, and political inequality that entrenched the ruling parties' power over institutions.
