Bayesian Framework for Finding Relevant Macro Factors in Affine Term Structure Models

We address the question of which unspanned macroeconomic factors are the best in the class of macro-finance Gaussian affine term structure models. To answer this question, we extend Joslin, Priebsch, and Singleton (2014) in two dimensions. First, following Ang and Piazzesi (2003) and Chib and Ergashev (2009), three latent factors, instead of the first three principal components of the yield curve, are used to represent the level, slope and curvature of the yield curve. Second we postulate a grand affine model that includes all the macro-variables in contention. Specific models are then derived from this grand model by letting each of the macro-variables play the role of a relevant macro factor (i.e. by affecting the time-varying market price of factor risks), or the role of an irrelevant macro factor (having no effect on the market price of factor risks). The Bayesian marginal likelihoods of the resulting models are computed by an efficient Markov chain Monte Carlo algorithm and the method of Chib (1995) and Chib and Jeliazkov (2001). Given eight common macro factors, our comparison of 2^8=256 affine models shows that the most relevant macro factors for the U.S. yield curve are the federal funds rate, industrial production, total capacity utilization, and housing sales. We also show that the best supported model substantially improves out-of-sample yield curve forecasting and the understanding of the term-premium.

About the Series
The weekly Center for Statistics and the Social Sciences (CSSS) seminar provides a forum for local and visiting scholars to present current research at the interface of statistics and the social sciences. Talks range in their level of technical detail and substantive motivation, and often result in spirited discussion. During the Winter and Spring 2019 quarters, we are celebrating CSSS’s 20th anniversary, with many speakers drawn from the population of past CSSS students. Current students may receive credit for attending the seminar by enrolling in CS&SS 590. All seminars are held at 12:30 on Wednesdays in Savery (SAV) 409 unless otherwise noted, and we will aim to conclude by 1:30. We provide coffee and light refreshments; attendees are also welcome to bring their lunch. For information or questions about the CSSS Seminars, please contact our Seminar Organizer, Will Brown (brownw@uw.edu). You can receive updates via a mailing list or calendar.
