| Outline of Final Research Achievements |
(1) In a small open economy with external financial shocks, it is found that there is a complementarity between monetary and cyclical macroprudential policies: a cyclical tax on foreign currency borrowing by banks combined with a relatively strict inflation targeting enhances welfare. (2) Using two-country models, the welfare gains of international monetary policy cooperation when there are financial frictions in the form of staggered loan contracts supplied by monopolistic banks. The same question is also investigated in the model with local currency pricing. (3) Using heterogeneous-agent macroeconomic models with incomplete markets and borrowing constraints, the welfare-maximizing taxation and debt policy has been analyzed. Also, the sovereign bond price dynamics is analyzed in a model with heterogeneous beliefs about the likelihood of a sovereign debt crisis.
