In this paper we present an evaluation of forecasts of a vector of variables of the German economy made by different institutions. Our method permits one to evaluate the forecasts for each year and then if one is interested to combine the years. We use our method to determine an overall winner...

In this paper we examine the quality of the initial estimates of the components of both real and nominal U.S. GDP. We introduce a number of new statistics for measuring the magnitude of changes in the components from the initial estimates available one month after the end of the quarter to the...

Does excluding food and energy prices from the Consumer Price Index (CPI) produce a measure that captures permanent price changes? To examine this question we decompose CPI inflation and "core" inflation into their permanent and transitory components using a correlated unobserved components...

Recent research examining U.S. macroeconomic data suggests that revisions may be much more important than traditionally assumed. This paper extends the analysis to Chinese data, where there has been substantial debate about data quality for some time. The key finding in this paper is that indeed...

Although there have been many evaluations of the Fed Greenbook forecasts, we analyze them in a different dimension. We examine the revisions of these forecasts in the context of fixed event predictions to determine how new information is incorporated in the forecasting process. This analysis...

We decompose core CPI and the food and energy CPI measures into permanent and transitory components using a correlated unobserved components model, to examine the behavior of core CPI when subject to shocks and to examine the claim that core CPI captures the persistent part of headline CPI. We...
