To fill the gap,... Two sub-databases providing information on: Nominal and Real Effective Exchange Rates (NEER & REER): 187 countries; three different weighting schemes two panels of trading partners (186 and top 30) period: 1973-2016 Behavioral Equilibrium Exchange Rate (BEER) estimates and corresponding Currency Misalignments (Mis): 182 countries; Different specifications/options period: 1973-2016 3 / 26

The Effective Exchange Rates (ERR) database: methodological features The indices Real effective exchange rate (REER): weighted average of real bilateral exchange rates against each trade partner: REER i,t = NEER i,t CPI i,t CPI Foreign j,t (1) where NEER i,t = N j=1 S ij, wij,t t is the nominal effective exchange rate of country i; CPI i,t stands for the Consumer Price Index of country i; CPI Foreign j,t = N j=1 CPI j wij,t t ; w ij,t is the trade-based weight associated to partner j. 6 / 26
The Effective Exchange Rates (EER) database: methodological features The trade weights ( M i,t w ij,t = M i,t + X i,t ) w Imp. ij,t + ( X i,t M i,t + X i,t ) w Exp. ij,t (2) where w Imp ij,t and w Exp ij,t are partner country j s import and export weights; M i,t and X i,t are total imports and total exports of country i. The import and export weights of each partner j are: w Imp ij,t = M j i,t /M i,t (3) w Exp ij,t = X j i,t /X i,t (4) where M j i,t (resp. X j i,t ) denotes import (resp. export) flows into (of) country i from (to) country j at period t. 7 / 26

Introduction The BEER approach: why? The Fundamental Equilibrium Exchange Rate (FEER) approach Normative content The Behavioral Equilibrium Exchange Rate (BEER) approach No ad hoc judgements (Positive approach) Data availability Wider coverage (AEs, EMEs, DCs) The External sustainability approach (ESA) Normative content All the approaches are complementary Consultative Group on Exchange Rate Issues (CGER; IMF) 17 / 26
