Financial Structure and Instability in an Open Economy

The subprime loan mortgage crisis has revived scholarly interest in Minsky’s financial instability hypothesis. The related mathematical models present two types of Minskian financial structures, which we identify as the lenders’ risk type (LR) and the hedge, speculative and Ponzi type (HSP). We construct macrodynamic models in a fixed and floating exchange rate system which considers both the LR and HSP financial structures. We examine the effects of international capital mobility and international lenders’ risks and demonstrate the significance of the LR and HSP financial structures in the fixed and floating exchange rate system. We emphasize the significance of stable financial structures in order to stabilize dynamic systems in an open economy.
