Transfer Pricing as a Career Option

Hi Going Concern Community,
I’m been doing some research into Transfer Pricing and it seems interesting. I know it involves skills from accounting, economics,and law(among other disciplines). I already have a BBA in accounting and want to know if  a Masters in Economics, JD, or both would be useful to break into the industry. It would also be appreciated if anyone could comment on the growth of tax litigation/controversy in regards to transfer pricing with the  OECD BEPS project being implemented across the globe.
