The Effect of Nonlinearity between Credit Conditions and Economic Activity on Density Forecasts
This paper examines the effect of nonlinearities on density forecasting. It focuses on the relationship between credit markets and the rest of the economy. The possible nonlinearity of this relationship is captured by a threshold vector autoregressive model estimated on US data using Bayesian methods. Density forecasts thus account for the uncertainty in all model parameters and possible future regime changes. It is shown that considering nonlinearity can improve the probabilistic assessment of the economic outlook. Moreover, three illustrative examples are discussed to shed some light on the possible practical applicability of density forecasts derived from non‐linear models.
