It discusses some of the conceptual and the technical aspects of this literature by using one-sector model of Benhabib and Farmer (1994). An overview of dynamic models under small open economy is given, and their theoretical properties and empirical plausibility are examined. After the survey of the models generating indeterminacy under small open economy, which the external effects in production sectors play an important role, we provide a simple framework whose long-run equilibria are indeterminate because of consumption externalities. Finally, we show the mechanisms that give rise to indeterminate equilibria.}, pages = {87--106}, title = {国際マクロ経済学における不決定性}, volume = {59}, year = {2011} }
