Serving as a volunteer is gratifying and rewarding, but by nature it is also considered a risky decision. Volunteering risk may come from the lack of sufficient training, asymmetric information between volunteers and managers, and the lack of support and protection from nonprofit organizations. Abundant studies discuss volunteering behaviors based on demographics. However, people's decisions are mainly determined by their own preferences rather than demographic differences. Accordingly, this study hypothesizes that individual risk propensity is an important predictor for volunteering behaviors. Using a nationally representative data set, this study finds that risk-accepting individuals are more likely to volunteer than their risk-averse peers. Also, the former tend to volunteer more frequently than the latter once they decide to be part of the volunteer labor force. Several managerial implications and volunteer recruitment strategies for nonprofit organizations are discussed.
