This paper incorporates the interdisciplinary New Institutional and Transaction Costs Economics (combining Economics, Organization, Law, Sociology, Behavioral and Political Sciences) and suggests a holistic framework for analysis of agrarian contracts. First, it specifies type and importance of different mechanisms of governance of agrarian activity. Second, it defines the essence, and classifies types and features of agrarian contracts. Next, it identifies technological, institutional, behavioral, dimensional, and transaction costs factors for contractual choice, and specifies effective modes for contractual arrangements in agriculture. Finally, it determines the effective boundaries and sustainability of farm and agrarian organizations.
