Identify the findings of the study that involved 6 million employees across 275 firms conducted to analyze the impact of profit-sharing plans. Multiple select question. Employee motivation was higher in companies that used profit sharing as a pension program than in companies that did not. Profit-sharing plans worked better in larger companies than in smaller companies. Productivity was higher in profit-sharing plans where payouts were made in the same year than in plans where the payment was deferred. Companies that used profit-sharing plans had 3.5-5.0 percent higher profits than companies that did not use these plans
