A Note on Shibata's Second Neutrality Theorem in an International Trade Model
The present note reconsiders Shibata's second neutrality theorem in a model that consists of two small countries, two tradable goods, and two primary factors of production. We demonstrate that the second neutrality theorem is valid under certain conditions; that is, to mitigate the negative effects of public bads, the governments must have direct control over the factors of production. Otherwise, the theorem does not hold in general.
