The non-linear nature of country risk and its implications for DSGE models
MetadataShow full item record
Country risk premia can substantially affect macroeconomic dynamics. We concentrate on one of their most important determinants - a country’s net foreign asset position and - in contrast to the existing research - investigate its nonlinear link to risk premia. The importance of this particular non-linearity is twofold. First, it allows to identify the NFA level above which the elasticity becomes much (possibly dangerously) higher. Second, such a non-linear relationship is a standard ingredient of DSGE models, but its proper calibration/ estimation is missing. Our estimation shows that indeed the link is highly nonlinear and helps to identify the NFA position where the non-linearity kicks in at approximately -70% to -75% of GDP. We also provide a proper calibration of the risk premium - NFA relationship which can be used in DSGE models and demonstrate that its slope matters significantly for economic dynamics in such a model.
