Mysteries of economics forecasting explained (Peru finance ministry edition)

El Comercio is today running this report on how Peru's Ministry of Economy and Finances (MEF) is forecasting the local currency, Peru's Nuevo Sol (PEN), to reach a foreign exchange rate of S/2.90 versus the US Dollar in 2012. The MEF forecast is part of its tome-like "MultiAnnual Macroeconomic Update" published last weekend.
