Indeterminacy in a small open economy Ramsey growth model

This paper presents a small open economy version of the J. Benhabib and R. E. A. Farmer (1996, J. Monet. Econ. 37, 421-443) two sector optimal growth model with production externalities. It is shown that indeterminacy is cons iderably easier to obtain under a regime of perfect world capital markets t han in the closed economy variant. Furthermore. the result is not dependent on a high labor supply elasticity since that input is fixed. The paper als o examines a variant which takes into account external borrowing constraint s and it is shown that the qualitative results on indeterminacy remain basi cally unaffected by this extension.
