'Lean' versus 'Rich' Data Sets: Forecasting during the Great Moderation and the Great Recession
            We evaluate forecasts for the euro area in data-rich and ‘data-lean'  environments by comparing three different approaches: a simple PMI model based  on Purchasing Managers' Indices (PMIs), a dynamic factor model with euro area  data, and a dynamic factor model with data from the euro plus data from national  economies (pseudo-real time data).
