This technical report examines the patterns and predictors of asset decumulation in retirement, particularly focusing on the role of financial literacy. The study analyzes data from the Health and Retirement Study, covering individuals who reached age 65 between 1995 and 2008. It highlights how decumulation patterns differ based on wealth levels at retirement, showing that wealthier retirees tend to spend down their assets more slowly compared to those in lower wealth quartiles. The findings indicate that individuals in the second wealth quartile deplete their assets rapidly, while those in the third and fourth quartiles experience slower decumulation. The report also discusses the impact of financial literacy, revealing that individuals with higher financial literacy retain more of their wealth over time and are more likely to accumulate assets after age 65. The implications of these findings suggest that wealth decumulation is influenced by both asset type and individual financial capabilities, which are critical for understanding financial security in later life.
