Opinion Polarization in a Parliamentary Institution Generates Extreme Legislation

How does opinion polarization over matters of moral conviction affect the legislative outcome of parliamentary institutions?

A trivial feature of the model is that the resistance of representatives towards conceding on matters of moral conviction is an inverse function of available transferable benefits, implying the symptoms of opinion polarization are equally triggered by shifts in the institution's buying power
