My research explores ways to nudge consumers toward decisions that promote sustainability in its broad sense, encompassing both financial and environmental aspects. I aim to better understand the psychological mechanisms that hinder consumers from adopting sustainable behaviors, such as long-term saving and energy efficiency. Based on these insights, I study potential behavioral interventions designed to guide consumers toward better decisions. I focus on two main streams of research: sustainable finance, and environmental sustainability. I conduct empirical research involving experiments (Randomized Controlled Trials), in both field and lab.
