Equilibrium indeterminacy in one-sector small open economies. The role of international labor migration

This paper presents a Ramsey-like dynamic small open economy with endogenous labor migration. In the model, the domestic economy is free to borrow or lend as much as it wants at the given world interest rate, and individuals are supposed to be free to move from a country to another in response to the emergence of a wage differential between countries. My analysis can be ideally split in two parts. Initially, I propose a baseline model in which only natives are allowed to save and invest in capital assets and traded bonds, whereas immigrants are credit constrained. Next, I provide an extension in which all individuals, including immigrants, have full access to international financial markets. I find that the steady state is always local indeterminate, and that the adjustment dynamics of the competitive equilibrium is dependent upon the initial level of the immigration ratio.
