Bitcoin expert on Bloomberg: Increasing the block size limit will increase the supply of bitcoins and cause the price to fall, by the law of supply and demand.
Oh, and in matters of bitcoin should trust only the opinion of people with Ph. D.
Well, I can agree with that part.

Ok, to play devil's advocate he's sort of right in a way that laymen will misinterpret and not understand. Recall the basic economics equation MV=PQ
basically, money supply (M) multiplied by velocity (V) equals Price of goods (P) times quantity of goods (Q).
Increasing block size means that bitcoin will have the POTENTIAL of greater velocity, which (if M remains constant or growing at a constant rate) means that (assuming quantity of goods remains constant) Price of goods goes up in BTC which means that the value of Bitcoin will fall.
that's a lot of assumptions that I don't think are warranted. Q will likely go up massively as the utility of the network expands. For example: people will buy blockspace for timestamps, title records, etc. also microtransactions.
