Rawley Heimer studies individuals' financial decisions in risky asset markets and conventional debt markets. Some of his research shows that social networks and low probability events are crucial in developing distorted beliefs, leading to trading mistakes and other costly financial errors. He also studies how the political and legal environment affects households' access to credit. This research has been published in leading finance journals, such as the Journal of Finance, Journal of Financial Economics, and Review of Financial Studies. Popular media outlets and trade publications, such as the Wall Street Journal, Quartz, TheStreet, Bloomberg, MarketWatch, Kiplinger's, and NPR Morning Edition, have profiled Heimer's research.
