Final answer:
Savings of $12/mo per plan on Easy Share Accounts are typically achieved through automatic enrollment, as suggested by behavioral economics, which increases participation rates for such savings programs.
Step-by-step explanation:
The question pertains to savings on Easy Share Accounts and mentions a monthly saving of $12 per plan. To achieve these savings, customers or employees typically need to be enrolled in a program that offers such a benefit. Insights from behavioral economics have shown that when people are automatically enrolled in savings plans, higher participation rates are observed than when individuals have to actively enroll themselves. This concept applies to various types of savings programs, including retirement plans, health savings accounts, and shared mobile or data plans where users get a discount for being part of a group account.
For instance, a mobile service provider might offer a discount under its 'Easy Share Account' if all members on the plan are automatically enrolled, as opposed to requiring each person to opt-in individually. The automatic-enrollment feature simplifies the process and encourages more users to take advantage of the shared savings opportunity.
