A comparison of direct and iterated multistep AR methods for forecasting macroeconomic time series

Abstract: Abstract"Iterated" multiperiod ahead time series forecasts are made using a one-period ahead model, iterated forward for the desired number of periods, whereas "direct" forecasts are made using a horizon-specific estimated model, where the dependent variable is the multi-period ahead value being forecasted. Which approach is better is an empirical matter: in theory, iterated forecasts are more efficient if the one-period ahead model is correctly specified, but direct forecasts are more robust to model misspeci… Show more

“…The Error Correction Model (ECM) assumes that there is a long run relationship between the level of the exchange rate, s t , and the level of the fundamentals, f t ; thus, in forecasting the rate of growth of the exchange rate, it includes a correction term that captures 34 Note that the forecast is based on a parameter directly estimated from a regression of the current rate of growth of the exchange rate on the lagged value of the fundamental. See Marcellino, Stock and Watson (2006) for a review of direct and iterated forecast methods. 35 See Meese and Rogo¤ (1983a,b) for the monetary model; for the monetary, productivity and net foreign assets measures; and Bacchetta, van Wincoop and Beutler (2010) for the monetary model augmented by unemployment and oil prices.…”

“…Using this criterion in small samples requires special attention, without which the forecasting uncertainty may increase. Therefore, the RMSE criterion is also used for assessing the forecasting accuracy (Marcellinio et al 2006), so that the forecasting error (in terms of RMSE) would be minimized for the minimum Akaike criterion. The following equation is used for AIC computation.…”
