The aggregation of the variables that compose an indicator, as GDP, which should be forecasted, is not mentioned explicitly in literature as a source of forecasts uncertainty. In this study based on data on U.S. GDP and its components in 1995-2010, we found that GDP one-step-ahead forecasts made...

In this paper I built forecasts intervals for the inflation rate in Romania, using the quarterly predicted values provided by the National Bank of Romania for 2007-2010. First, I used the historical errors method, which is the most used method, especially by the central banks. Forecast intervals...

Based on data of inflation forecasts provided quarterly by the National Bank of Romania, forecast intervals were built using the method of historical forecast errors. Forecast intervals were built considering that the forecast error series is normally distributed of zero mean and standard...

The aggregation of the variables that compose an indicator, as GDP, which should beforecasted, is not mentioned explicitly in literature as a source of forecasts uncertainty. In thisarticle we demonstrate that variables aggregation is an important source of uncertainty inforecasting and we...

In crisis periods many malfunctions affect the economic environment. The forecasting process is also influence by the negative evolution of the macroeconomic variables. It is hard to predict the economic behavior of many indicators because of the lack of stability of the economic world. It is...

Inflation rate, unemployment rate and interest rate are some of the most important indicators used at macroeconomic level. These variables present an important interest for the central banks that establish the monetary policy (infl ation target), but also for the government interested in public...

The objective of this research is to present some accuracy measures associated to forecast intervals, taken into account the fact that in literature some specific accuracy indicators for this type of prediction have not been proposed yet. For the quarterly inflation rate provided by the National...

For a certain macroeconomic variable more predictions based on different methods could be made. The essential problem is to establish the most accurate forecast, using different indicators. The econometric modeling is one of the most used forecasting method. A strategy to improve the accuracy of...

The objective of this research is related to the comparison between the government planning for the revenues and our own forecasts based on an econometric model. An auto-adaptive model was constructed for the revenues, taking into account the previous expectations regarding the government...
