"Systemic risk is propagation risk. In a systemic crisis, an initial shock spreads beyond its own market, start a vicious spiral of price shocks and disrupt the real economy. We have learned that liquidity runs are a primary cause of propagation. Banks that suffer rapid withdrawals of short- whosale funding cause rapid fire sales in a panic, forcing others in fire sales, and propagating the shock. Accordingly, we propose to introduce liquidity risk charges as a macro prudential policy tool. Taxing short uninsured term funding is aimed at making banks internalize the negative systemic effects of fragile funding strategies. A macro prudential authority can manage the charges to prevent excess build up of liquity risk during good times. "

"With hindsight, the most glaring gap in Basel II was its neglect of unstable short term funding. Rapid capital withdrawals was the primary source of propagation in the last crisis. This occurred in combination with opaque assets. Yet other episodes of opaque asset overvaluation, such as the internet bubbles, produced huge losses but basically no propagation across markets. The explanation is simply that these investments were funded with equity. Once losses materialized, investors could not escape, and took their losses without spreading them. "

"Novel early stage ideas face uncertainty on the expertise needed to elaborate them, which creates a need to circulate them widely to find a match. Yet as information is not excludable, shared ideas may be stolen, reducing incentives to innovate. Still, in idea-rich environments inventors may share them without contractual protection."
