Predictable Obamacare Result

You can't blame this on those greedy corporations, a school district is doing this:

Roanoke City Public Schools will become the first area division to outsource its substitutes to a New Jersey-based company.

Beginning Jan. 5, Source4Teachers will staff the city’s substitute teachers, substitute aides and substitute clerical workers.

The move to privatize subs will cost about $1.6 million, and it is unclear whether it will save money. Officials have said it will help tame costs associated with the Affordable Care Act, as well as the law’s tracking and reporting requirements.

It would almost be criminal if they didn't do this to save the taxpayers' money.

But let's be up front about what's going on here--an employer is responding to (dis)incentives built into a law by acting in its own interest.  What field teaches us that this would be so?   What else can that field teach us about Obamacare and its implementation?
