I think the family in my country is considered a group of individuals seeking recognition of their rights individually, without conceiving the family as a social subject, that inside in how public policy is conceived
You may want to look up the Nobel laureate Gary Becker theorems about the family. In particular look up his 1. Rotten-Kid Theorem in which the metaphor of a child as a durable good is used, and 2. The Theory of Marriage in which emotions and love are treated as commodities.
In his Rotten Kid Theorem, Becker wrote that “The Rotten Kid Theorem implies that for "…rotten kids" to act "rotten", they must have "rotten parents" and that "rotten wives" must have "rotten husbands". Even selfish and envious children or wives act as if they are altruistic towards their siblings and parents or husbands if parents or husbands are altruistic towards them, and act as if they are envious towards their parents or husbands if these persons are envious towards them.”
One can demonstrate this by writing out the utility function for a husband, h, and two kids, Jane, j, and Tom, t. Suppose Tom is considering an action that will affect Jane’s utility, then their choices can be joined in a utility function say Ψ=Ψ(Z_t,Z_j), where the partial derivative Ψ_j
it may depend on what sort of questions you are trying to answer - for families with intergenerational risk of involvement with criminal justice services or government or non-government family support agencies, early intervention holistic approaches seem to be embedded in policy (at least in Australia and the UK) and there has been a growing trend toward a gendered focus in general in Australia (the Department of Scoial Services website, and the Australian Institute of Health and Welfare each have a series of publications with solid reference lists). The Washington Institute of Public Policy also has some great stuff.
