Genoeconomics is the study of how genes, or different types of DNA, affect people's economic behavior. It combines genetics (science of genes) and economics (study of money and how people use it). In genoeconomics, researchers try to figure out how genetics can explain why some people make better financial decisions than others. Scientists look at how our genes might affect our decisions around saving, investing, spending, and working. For example, they might look to see if there are differences between people with different versions of genes related to the brain, which might explain why some people are better at finances than others.
