Daniele Girardi is assistant professor of Economics at UMass Amherst. His main research interest is the application of explicit and credible research designs for the identification of causal effects in macroeconomics. He is applying this approach in two main research projects. The first investigates the long-run effects of aggregate demand dynamics. The second studies the effect of institutional/political factors on macroeconomic outcomes. He received his PhD in Economics from the University of Siena (Italy) in 2016, with a thesis on aggregate investment which was awarded the “Pierangelo Garegnani” Thesis Prize 2016.
