Dr. Paul Kaplan explains that life cycle models provide a holistic view of financial planning, focusing on consumption as the ultimate goal. He contrasts this with conventional approaches that may treat saving, spending, and asset allocation as disjointed elements, emphasizing that his model integrates these aspects through net worth optimization.
“The insights that just come of any life cycle model are very essential and important in financial planning, which is taking a holistic view of the whole process and focusing on consumption because, after all, the purpose of saving and investing is to be able to fund a person's consumption smoothly over the course of their lifetime.”
“The conventional approach is that it might have a saving role, it might have a spend down role during retirement, and it may have an asset allocation, all of which might be disjointed from each other.”
“So the fundamental insight is all these things work together and that consumption should be the focus of any kind of plan for a lifetime.”
