‘sectorgap’ enables the estimation of a large Bayesian state space model for economic trend cycle decomposition. Economic output is decomposed into potential output and the output gap, consistent with individual sub-sectors of the economy and a set of economic indicators, e.g. regarding labor market and inflation dynamics.

Determining potential output and the output gap - two inherently unobservable variables - is a major challenge for macroeconomists. This paper presents the R package sectorgap, which features a flexible modeling and estimation framework for a multivariate Bayesian state space model identifying economic output fluctuations consistent with subsectors of the economy. The proposed model is able to capture various correlations between output and a set of aggregate as well as subsector indicators. Estimation of the latent states and parameters is achieved using a simple Gibbs sampling procedure and various plotting options facilitate the assessment of the results.
