Scientific contributions
In predictive econometric modeling Diebold is best known for the "Diebold–Mariano test" for assessing point forecast accuracy, methods for assessing density forecast conditional calibration, and for his text, Elements of Forecasting.

In financial econometrics Diebold is best known for his contributions to volatility modeling, including the Diebold-Nerlove "latent-factor ARCH model" and the Andersen-Bollerslev-Diebold extraction of "realized volatility" from high-frequency asset returns;

In macroeconometrics Diebold is best known for his work on the macro-finance interface and his work on real-time macroeconomic monitoring, particularly the Aruoba–Diebold–Scotti ("ADS") Business Conditions Index, now maintained by the Federal Reserve Bank of Philadelphia.

Additional noteworthy contributions include the Diebold–Li "dynamic Nelson-Siegel" yield-curve model and its extensions; and the Diebold–Yilmaz framework for dynamic network connectedness measurement and visualization.
