Household production function
Consumers often choose not directly from the commodities that they purchase but from commodities they transform into goods through a household production function. It is these goods that they value. The idea was originally proposed by Gary Becker, Kelvin Lancaster, and Richard Muth in the mid-1960s. The idea was introduced simultaneously into macroeconomics in two separate papers by Jess Benhabib, Richard Rogerson, and Randall Wright (1991); and Jeremy Greenwood and Zvi Hercowitz (1991).
