The IMF Working Papers series is designed to make IMF staff research available to a wide audience. Almost 300 Working Papers are released each year, covering a wide range of theoretical and analytical topics, including balance of payments, monetary and fiscal issues, global liquidity, and national and international economic developments.
This paper presents an empirical analysis of the medium- and long-term determinants of the real (effective) exchange rate (RER) of the Bulgarian lev using elements from the natural real exchange rate (NATREX) and the behavioral equilibrium exchange rate (BEER) approaches. The results indicate that the RER is driven by fundamentals, including labor productivity, terms of trade, world real interest rates, gross savings, and foreign direct investment. The model also shows that there is no significant misalignment of the Bulgarian lev.
