Agricultural household models (AHMs) were proposed as a basic model to study joint determination of production organization and consumption choice of farm households. This study reviews the literature of AHMs and summarizes three representative studies to reveal features and implications of recent studies. Recent studies of AHMs introduce "full income" from theory of home production and "shadow prices" which equate the demand and supply of goods and services within the household. Introduction of these concepts allows theoretical analysis of AHMs to conform to standard microeconomics analysis. Furthermore, recent studies of AHMs use "non-separable" models to emphasize relevance of the consumption side of AHMs. Imperfect markets and transactions costs are particularly important for farm households in developing countries and cause "non-separability", namely dependence of their production organization on their consumption choice. Consequently, test of the "separability" and analysis of this dependence become the central concern of recent studies. Allowing for greater availability of microdata on farm households and recent development of microeconometrics, I believe that AHMs will still remain useful tools for studying the behavior of farm households.
