Financial planners often work with clients that disagree about how to invest their retirement savings. This research uses economic bargaining theory as a framework to model the effect of agreement or disagreement on financial satisfaction. Based on the received literature disagreement amongst spouses reduces their financial well-being. Planners can help mediate financial disagreements that may arise because of poor bargaining amongst spouses. Planners that help clients reslove disagreements will have better relationships with their clients which will benefit both their practice and clients life satisfaction. We use RAND HRS and HRS LB Psychosocial and Lifestyle questionairres as data sets to support our hypothesis that successfully bargained or cooperative spousal investment decisions are more likely to have higher levels of financial satisfaction.
