Abstract
We implement a novel nonlinear structural model featuring an empirically successful frequency-dependent and asymmetric Phillips curve; unemployment frequency components interact with three components of core personal consumption expenditures (PCE)—core goods, housing, and core services ex-housing—and a variable capturing supply shocks. Forecast tests verify accuracy in its unemployment–inflation trade-offs, crucial for monetary policy. Using this model, we assess the plausibility of the December 2022 Summary of Economic Projections (SEP). By 2025Q4, the SEP projects 2.1% inflation; however, conditional on the SEP unemployment path, we project 2.9%. A fairly deep recession delivers the SEP inflation path, but a simple welfare analysis rejects this outcome.
期刊介绍：
The Journal of Forecasting is an international journal that publishes refereed papers on forecasting. It is multidisciplinary, welcoming papers dealing with any aspect of forecasting: theoretical, practical, computational and methodological. A broad interpretation of the topic is taken with approaches from various subject areas, such as statistics, economics, psychology, systems engineering and social sciences, all encouraged. Furthermore, the Journal welcomes a wide diversity of applications in such fields as business, government, technology and the environment. Of particular interest are papers dealing with modelling issues and the relationship of forecasting systems to decision-making processes.
