Pension reforms in many countries have resulted in more choice and risk to individuals, decreasing the dependability on State public pensions. However, it is not clear how research has addressed this issue and how much is know about retirement saving decisions. With this paper, we provided two major contributions to the literature on retirement saving. As a starting point, we developed a general chart of retirement saving choices, extending the work of Hurd and Panis (2006). These authors focused exclusively on choices at job change or retirement age and we extended their diagram to all main decisions at each stage of retirement saving, providing a more comprehensive framework. We then used this diagram as the yardstick to perform the systematic review and evaluate the breadth of research in the last 20 years. We found 130 papers and identified the most studied retirement choices and the under-researched areas. Most papers focused on asset allocation, decision to save and contribution rate. Less attention was given to decisions at retirement age and voluntary savings. Furthermore, very few papers studied the psychological and social influences in retirement saving decisions. Policy implications and future research are discussed.
