We propose a new methodology to identify the sources of models’ forecasting performance. The methodology decomposes the … models’ forecasting performance into asymptotically uncorrelated components that measure instabilities in the forecasting … understanding the causes of the poor forecasting ability of economic models for exchange rate determination. …

Realized volatility of stock returns is often decomposed into two distinct components that are attributed to continuous price variation and jumps. This paper proposes a tobit multivariate factor model for the jumps coupled with a standard multivariate factor model for the continuous sample path...

Forecast combination has become popular in central banks as a means to improve forecasts and to alleviate the risk of selecting poor models. However, if a model suite is populated with many similar models, then the weight attached to other independent models may be lower than warranted by their...

This paper reports real-time out-of-sample tests of the ability of the U.S. Index Leading Economic Indicators (LEI) to forecast the economy using "composition-changing" "as-published" versions of the LEI. It is an extension of recent work that focused on forecasts with a "composition-constant"...

Many authors have documented that it is challenging to explain exchange rate fluctuations with macroeconomic fundamentals: a random walk forecasts future exchange rates better than existing macroeconomic models. This paper applies newly developed tests for nested model that are robust to the...
