More than five years after its enact­ment there still are many ques­tions about whether Oba­macare is work­ing. Here are four of them.

My pre­vi­ous post dis­cussed what we know about Oba­macare as its third open enroll­ment sea­son begins.  Here are four major ques­tions about the future of Oba­macare that remain unanswered.

Oba­macare con­tains some very expen­sive sweet­en­ers to entice insur­ance com­pa­nies to sell through the exchanges. These include risk cor­ri­dor pay­ments and $20 bil­lion over three years in inapt­ly named “rein­sur­ance” pay­ments, mon­ey gov­ern­ment takes from par­tic­i­pants in group health plans and gives to insur­ers that par­tic­i­pate in the exchanges. Both are sched­uled to end in 2017.
