“And we have evidence (from the performance of banks) that in the real world, betting against long shots does not pay, which makes research a form of reverse-banking”

Factual Economics and markets

Evidence from the performance of banks shows that in the real world betting against long shots does not pay.

Mostly false False in substance, right in a detail.

Factual: Statements about the present or the past, checked against the record: did they hold up?

What would count as true or false

True if empirical evidence on bank performance shows that strategies equivalent to selling tail risk (collecting small steady gains while being exposed to rare large losses) produced net losses or underperformance over full cycles including crises (e.g. cumulative losses from 1982 or 2008 wiping out prior profits). Mostly true if the evidence supports this for major crisis periods or large banks but not uniformly. Mixed if the evidence is ambiguous or supports it only for some periods or institutions. Mostly false if it rests on real crisis losses but generalises them to a proven finding without systematic support, or if banks were net profitable over the cycle. False if systematic evidence shows that banks' tail-risk exposure paid off overall.

  11. E11 Do Big Bank Equityholders "Pay" for Bailout Insurance Over the Economic Cycle? Del Viva, Kasanen, Saunders and Trigeorgis (academic working paper, SSRN 3003900)

    “we find over the recent 43-year period equityholders in big banks paid fairly for TBTF bailout insurance in terms of equity returns.”

Reasoning

The evidence confirms large crisis losses: thrift industry losses in 1981-82 (E2), S&L clean-up costs of about $153-200 billion (E1, E5), bank losses to the FDIC of about $40 billion (E4), and a fall in a bank profitability figure to less than 1 percent at the end of 2008 (E10). However, the FDIC's own staff study reports that after the 1980s-early 1990s crisis came a dozen years of near-record profits (E8), and other sources describe record profits by 1994 (E6). An academic working paper finds that over a 43-year period equityholders in big banks paid fairly for too-big-to-fail bailout insurance in terms of equity returns (E11). The claim rests on real crisis losses but generalises them into a finding that the evidence presented does not systematically support, which fits the 'mostly false' criterion.
