Sovereign Default Risk, Macroeconomic Fluctuations and Monetary–Fiscal Stabilization

This paper examines the role of sovereign default beliefs for macroeconomic fluctuations and stabilization policy in a small open economy where fiscal solvency is a critical problem. We set up and estimate a DSGE model on Turkish data and show that accounting for sovereign risk significantly improves the fit of the model through an endogenous amplification between default beliefs, exchange rate and ...

The Challenged Sense of Belonging Scale (Csbs): A Validation Study in English, Arabic, and Farsi/Dari among Refugees and Asylum Seekers in Germany

This study introduces and investigates the validity of a brief scale measuring a challenged sense of belonging.

If both firms invest below a certain threshold, they only compete for those consumers already aware of their existence. Above this threshold, a firm is visible to all and the highest investment attracts all consumers. On the one hand, the existence of initially ...
