Introduction
Real Equilibrium Exchange Rates
• A “fair” value of a currency
• Getting the rate “right” is of great importance as the exchange rate influences competitiveness, price trends and other key macroeconomic variables.
• Various concepts of EER, depending on the definition of internal and external balance
FEER
• Fundamental equilibrium exchange rate
• FEER is the real effective er that secures internal and external balance for a country (or for a number of countries) simultaneously.
• Internal balance: NAIRU
• External balance: "sustainable" BoP position
FEER
• Advantages: does not require to much data, easily computed, and tested in the literature many times
• Drawbacks: normative elements, ad hoc definition of sustainable CA position, difficult to model trade, but…
• “Possibly the most popular of the underlying balance models” (Driver and Westaway, 2001)

Changes in trade patterns
• WTO 2000
• Bilateral agreements (first signed in 1996, by the end of 2004 25 agreements)
• EFTA 2001
• SAA 2001
• CEFTA 2003
• Return of export markets of former YU
Liberalization of capital flows
• New FX law in 2003
• Liberalization especially for firms
• Very few restrictions remain (some short-term flows, outflow of capital for residents, real estate, …) to be lifted by the end of SAA (2007)
Estimating FEER
Concepts of equilibrium ER
• market equilibrium: balances supply and demand of currency (Williamson)
• current equilibrium: consistent with the given or current fundamentals
• medium term equilibrium: consistent with the fundamentals at their equilibrium level
• long term equilibrium: in the long run, the capital stock and foreign debt are also endogenous and will be related, along with the real exchange rate, to long run fundamentals
Estimates of the EER
• PPP, HBS and NATREX are long-term concepts,
• On the short end, there are purely statistical approaches SVAR, BEER and CHEER
• FEER, DEER and PEER, refer to modeling the medium term equilibrium.
Estimating FEER
• Internal eq: potential GDP growth associated with low and "non-accelerating" inflation rate
• 1) Output gap
• 2) HP filter or BN decomposition
Estimating FEER
• External eq:
• 1) Macroeconomic balance approach (IMF)
• S(X)-I(Y)=CA (rer, Ybar)
• X and Y are arrays of explanatory variables (fiscal position, openness, population growth...)
• 2) "sustainable" current account position...

Conclusion
• The drawback inherent in the FEER method, cannot be resolved within the framework of FEER
• Often, another method is used along with FEER to verify its findings (BEER)
