[Star Wars] Do we know much of anything about the New Republic in Episode VII?

Once the Alliance to Restore the Republic was successful, did they include any safeguards to prevent or combat the corruption and inefficiencies of the Old Republic?  Was there a Chancellor, and if so, were their powers more limited in the aftermath of the dictatorial Empire? Were there any systems that were in either the Old Republic or Empire that said "no thanks" to the New Republic?  If the Old Republic has a Constitution, did the New Republic just use that, or did they re-draft, start from scratch?  

If there is no information yet on any of this, what seems likely?

Thanks!

There are novels dedicated to between the films.

IIRC Empire mostly gave up tamely. New Republic was formed but with a rotating capital and drastically curtailed powers for the Chancellor. First Order formed from parts of the Imperial military that fled to the Outer Rim.
