Summary

• Paper relates pre-crisis compensation measures (delta, vega, assets delta, asset vega) to observed post-crisis regulatory intervention enforcement action and closure

• It finds that larger delta, assets delta, asset vega increase probability of closure

Page 3: Michiel Bijlsma CPB Netherlands Bureau for Economic Policy Analysis

What I like about the paper

• Realized enforcement actions include consequences of taking unobserved or unregulated risk

• Looking at asset delta or asset vega really looks at the option value inherent in limited liability of shareholders.

• Table 4: compared to no intervention– all compensation variables are higher in closed banks

– all compensation variables are lower in for banks with enforcement action

• What’s going on?

Intervention

• Why not include decision of regulator in estimation?

• Could you also not use ‘further intervention’ category?

Comment 1b

• ‘Use multinomial logit model avoids sample selection problem’

• I’m not an econometrician, but – Multinomial model simply forces parameter to take a

single value

– How does this solve sample selection problem?

– Why not use sample selection models?

Comment 2

• High leverage implies a high sensitivity of value of shares to changes in asset value of the bank

• Asset delta is strongly correlated with leverage• High leverage also implies high sensitivity to

shocks such as a systemic banking crisis• Are you not measuring that leverage results in

higher risk?

Comment 3

• For small banks, regulators in the US use prompt corrective action

• This means that enforcement actions are triggered when for example regulatory capital levels or leverage ratios cross certain pre-determined thresholds

• To what extent is the variable ‘enforcement actions’ measuring whether thresholds are crossed?

Comment 4

• Is the large amount of regressions in the tables really necessary?

• What do the columns EA and Closure mean in the multinomial regression?

• Discussion of the relevant literature seems relatively limited
