Assuming that:
1. The current block size is 1MB
2. The block reward for a full block is 25.5BTC including tx fee
3. Miner is required to pay x% of reward penalty if he is trying to
increase the size of the next block by x%
If a miner wants to increase the block size by 1 byte, the block size
has to increase by 0.0001%, and the penalty will be 0.0000255BTC/byte.
For a typical 230byte tx that'd be 0.005865BTC, or 1.35USD at current
rate. This is the effective minimum tx fee.

Thanks for the link. I readily admit only having given
pay-to-future-miner a little bit of thought. Not convinced it sets a
minimal tx fee in all cases.

Schemes proposing to pay with difficulty / hashpower to change
block
size should be avoided. The miners incentive has always been
fairly
straightforward - it is rational to deploy new hashpower as soon
as
you can get it online. Introducing the concepts of (a) requiring
out-of-band collusion to change block size and/or (b) requiring
miners
to have idle hashpower on hand to change block size are both
unrealistic and potentially corrosive. That potentially makes
the
block size - and therefore fee market - too close, too sensitive
to
the wild vagaries of the mining chip market.
Pay-to-future-miner has neutral, forward looking incentives worth
researching.

I explained here why pay with difficulty is bad for everyone:
miners and users, and described the use of OP_CLTV for
pay-to-future-miner
However, a general problem of pay-to-increase-block-size scheme is
it indirectly sets a minimal tx fee, which could be difficult and
arbitrary, and is against competition
