Professor of Economics
My research focuses on intertemporal choice and household finance. It tests economic theories of how firms and consumers interact in markets and examines the merits of incorporating specific features of psychology into economic models. I am particularly interested in developing and testing innovations that build better financial services architecture for people and the institutions that serve them.
