We use past forecast errors to construct confidence intervals and other estimates of uncertainty around the Reserve Bank of Australia's forecasts of key macroeconomic variables. Our estimates suggest that uncertainty about forecasts is high. We find that the RBA's forecasts have substantial...

"Policy simulations for national economies with econometric models in general are done using a stand alone national model with exogenous export values and import prices. In a globalised world such an exercise is critical, since the policy in question may change the export prices and the import...

Die Risiken, die von der Schulden- und Vertrauenskrise in Europa ausgehen und die deutsche Wirtschaft belasten, haben zuletzt etwas nachgelassen; die Aussichten für die deutsche Konjunktur haben sich verbessert. Das Bruttoinlandsprodukt wird in Deutschland nach der Schwächephase im...

Since reducing the possibility of risks that can be avoided – including risks associated with the uncertainty of the future – is of great importance in the economic arena, generations of economists have struggled and are still struggling (with mixed results) to develop ‘reliable’...

It is commonly accepted that information is helpful if it can be exploited to improve a decision mak- ing process. In economics, decisions are often based on forecasts of up{ or downward movements of the variable of interest. We point out that directional forecasts can provide a useful framework...

The worldwide upswing has gained momentum since last autumn. The main cause for the high growth dynamics is a monetary policy that is very expansive not only in advanced economies, where the utilization rates for production capacities are mostly still low, but also in emerging market economies...

We propose an easy direct regression test to evaluate forecasts with respect to the naïve most recent observation alternative. The test is applied to thirteen macroeconomic forecasts published by the OECD. Four time horizons are considered: starting with eighteen months and declining to zero...
