Your words — are they credible? Or are they what Paul Oyer calls “cheap talk?” According to professor of economics Paul Oyer, how our words align with our actions isn’t just a matter of communication, but a matter of economics too. Economic concepts hold in all areas of life, which Oyer’s research has explored in everything from Uber driving to online dating. “Economics is everywhere,” Oyer says. “It's an incredibly powerful lens to analyze almost anything in the real world.”
