Gray Calhoun’s academic homepage

I’m Gray Calhoun, an Assistant Professor in the Economics Department at Iowa State. I work on Econometric theory, especially time series and applications to forecasting and forecast evaluation. I graduated with a PhD from UC San Diego in 2009, where I worked with Graham Elliott and Allan Timmermann.
