Government policy takes many and varied forms when applied to farm commodity markets. However, distinct policies may achieve similar effects. This paper considers the extent to which domestic market price regulations may affect imports and exports in addition to (or in absence of) the effects of explicit border measures. In particular, the paper investigates how U.S. domestic dairy policy is similar to or different from explicit state trading in commodities which also may substitute for or supplement explicit and transparent border measures.
