What will be the economic impact of the clampdown by the administration of US President Donald Trump on undocumented migrants?

Presenter Ed Butler puts this question to labour economist Giovanni Peri of the University of California, Davis. Meanwhile Phil Mercer reports from Australia on whether the ever-tightening immigration rules of that country have led to labour shortages in some sectors.

Plus, author and former Wall Street banker William Cohan gives an optimistic view about Mr Trump's ability to put in place sensible financial regulation, as the US President seeks to repeal the Dodd-Frank legislation that was passed in the wake of the 2008 global financial crisis.
