Abstract
Currently, state governments in the United States hold billions of dollars in unclaimed properties. This represents a welfare-loss for the owners who fail to recover the amount that is owed to them. However, no studies to date have attempted to systematically investigate the types of unclaimed property owed, the demographics of the non-claimants, or their reasons for non-claiming. This study will document these basic facts and test the effectiveness of providing information and assistance in recovering the unclaimed property. Additionally, the study provides an opportunity to investigate the consequences of receiving a large positive income shock on outcomes such as debt and credit. A subset of participants will be further randomized into receiving a light touch nudge to use their recovered property to pay down any high-interest debts. This study will be the first to focus explicitly on unclaimed property and is expected to contribute to our understanding of the barriers to recovering it and its impact on financial health.

Experimental Design
Experimental Design
Individuals will be contacted and enrolled in the study. After conducting a baseline survey, they will be randomized into receiving information or not. Of those who receive the information, half will be further randomized into receiving a nudge. I will then use the fact that the individuals were randomly assigned to different groups to estimate the local average treatment effect of each treatment arm and, in turn, to estimate impacts on financial behavior.
