When referencing cash, remember it is usually not really cash... & do we need special taxes on profits from patents?

Sir, I refer to Sarah Gordon’s “Be wary of the tax incentives in pharma’s deal financing” May 1, in order to make the following two observations:

First I believe that we should take the opportunity of the inequality frenzy that Piketty’s Capital has brought on, to discuss the treatment given to intellectual property right profits… as there can be little discussion that patents and similar, are among the biggest de facto inequality drivers. I, for instance, have held for some years that profits obtained under the umbrella of patents, and or of extravagant market shares, should be taxed higher than profits obtained from competing naked in the markets.

Second, when Gordon writes about the “$1.64tn of cash” that Moody estimates US companies held at the end of 2013, she would do better referring to “$1.64tn of liquid assets”… since we have no reason to believe the CFO’s of those companies keep stacks of notes hidden in their mattresses. I say this because we should not forget that any alternative use of these assets, will require their disposal… which has other effects in the market.
