Published in 2013, Scarcity: Why Having Too Little Means So Much, is an in-depth look at how scarcity of resources (time, money, etc.) impacts our ability to make decisions in our own best interest. Taken from a behavioral economics perspective, the book utilizes empirical evidence to broaden our understanding of the scarcity mindset. Most compelling for our work are the chapters directly addressing poverty.
