Economists have long expected an aging population to hamper growth for the simple reason that it means a smaller labor force. But new research has identified a potentially more powerful impact: Rapid retirements deprive companies of critical experience and knowledge, which undermines productivity across the entire economy. Demographics may thus be a critical factor in why the current economic expansion, which began as the first baby boomers qualified for Social Security, is the weakest on record.

One study found that productivity peaks at age 50, when productivity is 60% higher than for the average 20 year old.
