Final answer:
Subsidies are financial aids from the government to make health insurance products more affordable, particularly for lower-income individuals. The effectiveness of subsidies under the Affordable Care Act may be impacted by insufficient amounts provided or a lack of clear information available to eligible individuals.
Step-by-step explanation:
Subsidies refer to financial assistance provided by the government to help reduce the cost of health insurance premiums for eligible individuals based on their income levels. In the context of the Affordable Care Act (often abbreviated ACA or nicknamed Obamacare), subsidies are designed to make health insurance more affordable for those with lower incomes. More than half of the adults who did not enroll in a health plan because they could not find an affordable option and were not covered by other sources had incomes that qualified them for these subsidies. However, it remains unclear whether the insufficient subsidies across income levels are to blame for the low enrollment rates or if it is due to the lack of clear information about the available subsidy assistance and the actual net costs of insurance to potential enrollees.
