Research Questions • What are the effects (if any) of bank non-executive (i.e., middle-level managers’, henceforth NE) compensation policies on bank holding companies (BHC) risk-taking & on BHC value? • What are the determinants of such policies? In particular, to what extent does the market influence these incentives? • Are there any normative implications?
Motivation • In this paper, we re-examine the paradigm in law & finance literature whereas: • Executives determine NE incentives (e.g., Bebchuk & Fried, 2010). • Hence, bank risk-taking in response to NE incentives is an executive incentive alignment problem. • At least anecdotally (e.g., Rajan (2010)) NE incentives are important for bank risk taking & bank value. • Moreover, there is role for competition in determining NE incentives. • High-powered incentives to non-executives may lead to losing them to competitors.
Motivation “As long as the music is playing, you’ve got to get up & dance.” “We’re still dancing.” (Charles Prince)
Two Empirical Hypotheses • NE compensation policies in BHC before the crisis were only sensitive to increase revenue which resulted in excessive risk taking and, ultimately, lower bank value. • The distorted risk incentives underlying BHCs’ NE compensation policies were the product of a negative externality engendered by bank competition for NE services.
Prior Literature • Executive Compensation • Mixed evidence of the impact of CEO incentives on bank risk choices: • Bebchuk& Spamann (2010) and Cheng, Hong, & Sheinkman (2010). • Fahlenbrach & Stulz (2011). • Non-Executive Compensation • Overall literature scope is limited due to lack of cross-sectional data. • Experimental Data • Cole,Kanz & Klapper (2012) and Agarwal & Ben-David (2012). • Single Lender Data • Berg, Puri, & Rocholl (2012); Hertzberg, Liberti, & Paravisini (2011); and Gee & Tzioumis (2012). • Bank Risk Taking • Factors to influence bank risk-taking include • Deposit Insurance & Competition → Keeley (1990) among many others. • Ownership & Bank Regulation → Laeven and Levine (2009). • Bank Size → Demsetz and Strahan (1997). • Bank Franchise Value → Demsetz, Saidenberg, & Strahan (1997). • Monetary Policy → Landier, Sraer and Thesmar (2011). • Creditor Rights → Houston et al. (2010). • Risk Management Governance Mechanisms → Ellul and Yerramilli (2012). • .
Main Findings & Contributions During the financial crisis of 2007-2009: Pre-crisis Cash & Bonus NE compensation incentives had a significant positive effect on bank risk taking. Pre-crisis Stock NE compensation incentives had a significant negative effect on bank risk taking. Pre-crisis NE compensation incentives affected bank risk-taking primarily trough the part of these incentives specific to peer-group performance. Effects (1) and (3) above were stronger for banks w/ higher pre-crisis employee turnover & were weaker for banks w/ high pre-crisis excess NE compensation. Pre-crisis NE total compensation incentives to above-peer group performance were more important in determining bank risk taking. Pre-crisis NE Cash & Bonus compensation incentives lowered bank value, while NE Stock compensation incentives increased bank value.
Main Findings & Contributions • We contribute to the bank risk taking literature by testing for a new (to the literature) factor to influence bank risk taking & bank value. • As such, we document an inefficiency in bank NE compensation policies, caused by competition among banks to hire NE. • Methodologically, we outline a novel cross-sectional proxy for non-executive incentives. • Lastly, we contribute to the literature on employee stock-ownership, showing that ESOP plans add value through curbing employee risk taking incentives.
Data • Collect Data from a Bank Regulatory Database. • - Contains information on quarterly bank holding company accounting data collected by the Federal Reserve Bank of Chicago. • Data available for 77 BHCs: • Only banks w/ available data. • Banks that survived the financial crisis. • Other data: • - CRSP & Compustat (control variables). • - ExecuComp (CEO incentives). • - Option Metrics (Implied volatility).
Non-Executive Compensation Elasticity • Measures of Incentives (2002-2006): • Elasticity of NE compensation: quarterlyvariation of total compensation (net of executive pay) w.r.t. quarterly variation of Total Interest Income (TII), or Net Interest Income(incl. Loan & Losses Provisions), Total Income, or Net Income. • Maximal elasticity w.r.t. TII. • I.e., banks may reward volume rather than quality of loan products.
Non-Executive Elasticity & Bank Risk-Taking Measures of Risk (2007-2009): (1) Aggregate Risk; (2) Tail Risk; (3) Implied Volatility; (4) Z-Score. Non-executive cash compensation incentives positively impact bank risk-taking. In 2007-2009, the effect of NE cash compensation on risk is between 29.5% and 35.9%, instead effect of CEO compensation is, in some instances, 5.7%! Non-executive stock compensation incentives negatively impact bank risk-taking, but stock incentives are only 2%!

Competition Effect • To verify the relationship b/n competition for NE & their incentives, we consider: • - Sensitivity of NE compensation to BHC-specific performance & to peer-specificperformance. • - Impact of turnover (as proxy for competition). • NE compensation more sensitive to peer-specific performance. • Turnover positively impacts bank risk-taking. • Above-peer-groupcompensation (i.e., excess wage) negatively impacts bank risk-taking.
Peer Effects Estimation , where peer-specific performance defined as: and, where bank-specific performance, i.e., , is defined as the residual of a regression of on
Peer Group Choice • Empirical challenge is to identify the peer group as it is possible that peer group performance is driven by a common latent factor. • Potential solution: choose differentreference group for differentbanks. Heterogeneityin peer group choice allows us to use performance of “peer’s peer” as validinstrument to capture peer group’s performance. • Example. • Bank A1 has peer group, banks (A2, B1). • Bank B1 has a peer group, banks (B2, A1). • B2 performance relevant instrument for A1 performance because: • Relevant to A1 performance (influences performance of direct peer B1) & • Exclusive to A1 performance (i.e., achieves effect on A1performance only throughpeer group).

Robustness • Potential concern w/ empirical design is that both pre-crisis incentives & within-crisis risk exposure may reflect the level of BHC specialization in particular product lines (e.g. subprime loans). • If such product specialization is not controlled for in our tests, or if it influences dependent and independent variables in these tests in a non-linear way, a correlated-omitted variable bias in our empirical results would arise. • To address endogeneityconcern we use a comprehensive sample that extends from 1994 through 2010 and we use an alternative approach based on a system GMM estimation (Blundell and Bond (1998)).

Executive Compensation Reform? • Improving executive compensation practices not enough to solve the problem of excessive bank risk-taking. • NE risk incentives are independent from executive risk incentives. • The root of the problem is the negative externality produced by bank competition for non-executives.
Limiting Competition for Non-Executives • Direct: Making employment contracts relational. • Non-compete provisions for NEs: property rule. • Pigouvian tax on mobility: liability rule. • Clawback provisions contingent on mobility. • Excess compensation (contracts are less subject to renegotiation). • Pigouvian subsidy: Regressive tax (or tax deduction) on compensation based on tenure.
Non-Executive Deferred Stock Compensation • We find that stock compensation negatively impacts risk-taking, but is only 2% of total compensation. • Back-loading stock compensation into future periods increases employer specificity. • Rethink ownership between capital and labor providers when moral hazard is severe and cannot be fully controlled by contract. • Implementation strategies: • - Tough: Mandatory rules. • - Soft: Tax deductions.
