Forecasts of key macroeconomic variables may lead to policy changes of governments, central banks and other economic agents. Policy changes in turn lead to structural changes in macroeconomic time series models. To describe this phenomenon we introduce a logistic smooth transition autoregressive...

Experts may have domain-specific knowledge that is not included in a statistical model and that can improve forecasts. While one-step-ahead forecasts address the conditional mean of the variable, model-based forecasts for longer horizons have a tendency to convert to the unconditional mean of a...

-of-sample forecasting exercise to study money-income Granger causality, both linear and nonlinear, we believe is new to the literature. The … forecasting results do not suggest that money is nonlinearly Granger causal for output. In fact, they show that by allowing money … to nonlinearly Granger cause output, the forecasting performance of the STVECM is significantly worsened. …

We propose a simulation-based technique to calculate impulse-response functions and their confidence intervals in a market share attraction model [MCI]. As an MCI model implies a reduced form model for the logs of relative market shares, simulation techniques have to be used to obtain the...
