The Cognitive Economics Study (CogEcon) is designed to help understand the cognitive bases of economic decisionmaking. This effort was made possible through a partnership with the "Cognition and Aging in the USA" study (CogUSA), which is part of the Unified Studies of Cognition (CogUSC) led by cognitive psychologist Jack McArdle at the University of Southern California.

The Cognitive Economics Study has fielded four waves. The first wave, CogEcon 2008, collected information about income, work, assets and debts, financial sophistication, use of financial advice, among other topics. The second wave, CogEcon 2009, repeated many questions from CogEcon 2008 and contained new questions about changes during and responses to the financial crisis that started in late 2008. The third wave, CogEcon 2011, repeated many questions from earlier waves and containted new questions about income taxes and health literacy. We are currently processing data from the fourth wave, CogEcon 2013.

The CogEcon public release data are available through the Health and Retirement Study's data distribution system. There are currently two data products available, each containing a Stata data file and documentation. The first is the Public Core, which includes both CogEcon 2008 and CogEcon 2009, and the second is the CogEcon 2011 Public files.
