Convenience Yield and Real Exchange Rate Dynamics: A Present-Value Interpretation

open access: yesSocial Science Research Network, 2021
In this paper, we empirically investigate the relationship between the convenience yield of government bonds and the real exchange rates using monthly data spanning from 1999 to 2018. We extend the conventional models, based on present-value relationship
