2015-066: Nowcasting Business Cycles: a Bayesian Approach to Dynamic Heterogeneous Factor Models

Otmane El Rhazi, Antonello D'Agostino, Domenico Giannone, Michele Lenza, and Michele Modugno. We develop a framework for measuring and monitoring business cycles in real time. Following a long tradition in macroeconometrics, inference is based on a variety of indicators of economic activity, treated as imperfect measures of an underlying index of business cycle conditions. We extend existing approaches by permitting for heterogenous lead-lag patterns of the various indicators along the business cycles. The framework is well suited for high-frequency monitoring of current economic conditions in real time - nowcasting - since inference can be conducted in presence of mixed frequency data and irregular patterns of data availability. Our assessment of the underlying index of business cycle conditions is accurate and more timely than popular alternatives, including the Chicago Fed National Activity Index (CFNAI). A formal real-time forecasting evaluation shows that the fra mework produces well-calibrated probability nowcasts that resemble the consensus assessment of the Survey of Professional Forecasters.
