The financial crisis has shown that the commercial banks, the investment banks, the shadow banks, and sundry other financial institutions have assumed too much risk. It has also been demonstrated that when risks do materialize, the costs are borne by the taxpayers and the unemployed—not by bankers. The bankers have been playing “I win, you lose” with the general public. What happened to the capitalist system where everyone was supposed to pay for their own mistakes, not for those of others?

The reforms proposed to deal with this problem have, by and large, been limited to reformulated capital requirements for banks and macro-prudential supervision of the system. To date, the ideas advanced are less than reassuring.
Fixing the distortion at source
What has received little attention so far is the structuring of liability in banking. In the early days of fractional reserve banking, bank owners were subject to unlimited liability. In the US, double liability for bank shareholders was common up to the Great Depression. All US investment banks were partnerships into the 1970s and the last one, Goldman Sachs, only converted itself into a limited liability corporation about a decade ago. Back in the 1970s, US financial sector liabilities were less than 20% of gross domestic product. Today the figure is close to 120%. Leverage has increased enormously. Back then, stringent liability rules inhibited risk-taking. In the days when such liability provisions applied to banks, “conservative” was the adjective habitually attached to “banker”. It does not fit the high-stakes gambling “quants” of recent years.
If bank stockholders were subject to double liability today, it would hardly be possible to attract enough capital into banking for the needs of a modern economy. Most stockholders have little or no ability to control the risks that bank managements assume. Liability provisions, however, could be applied directly to managers rather than to stockholders so as to change the incentives to assume risk that bank executives face.
Equity for shareholders and equity for employees: the E-shares proposal
To do this, one would first have to create a special type of equity for bank employees. These E-shares would be subject to double liability. If the bank were to fail, the holders would be liable for a sum equal to the value of their shares on the date that they were originally received. E-shares would be non-marketable but exchangeable one-for-one for ordinary shares at market value five years after the owner has left the the financial institution in question.
The second element of such a liability scheme would regulate the extent to which executive compensation would have to be in the form of E-shares. Lower-level employees who are not among the decision makers of the bank should naturally not be part of the programme. So the first $150,000—or wherever the poverty line is supposed to go in banking nowadays—would be exempt. Compensation would be entirely in ordinary salary. Starting at some such level part of compensation would have to be in E-shares with the proportion rising to, say, 80% at the CEO and CFO level.
Obviously, the specific rules of a liability scheme of this sort can be tweaked in a number of ways.
Benefits of linking decision makers’ liability to risk-taking
Within wide limits,?such a scheme should have a socially beneficial effect on risk attitudes within the institutions affected—it might even bring back the conservative banker species from the brink of extinction.
The policy can be expected to have some interesting subsidiary effects as well. In the internal politics of banks, double liability should strengthen the influence of risk managers and make it less countercyclical than it has been in recent years. Some of the admirable capacity for innovation that the financial sector has exhibited in recent years would be diverted to risk management (although, no doubt, much of it would go towards circumventing the accountability that the double liability system would impose).
Within financial institutions, double liability would cause executives to take interest in the activities of divisions for which they have no direct responsibility. On occasion, one must imagine, dissension might severely strain internal relations. For the individual bank, all this would raise the cost of operations, but from the standpoint of systemic risk the effects would be desirable.
These predictable consequences of double liability would reduce the perceived advantages of conglomerate banking. It will not solve the too-big-to-fail problem by itself, but it just might induce the big banks to spin off some lines of business.
We would expect to see lower leverage ratios—and a moderation in executive compensation packages. This way of doing it just might work better than Basel rules of leverage and government-imposed limits on compensation.
A variant of the scheme would make E-shares marketable. It would be somewhat more cumbersome to administer. Investors who are not bank employees would have to post collateral adequate to back the double liability and records tracking all transfers of shares would have to be maintained. It might, however, make the market more efficient. The discount on E-shares relative to ordinary shares would tell the market what insiders think of the bank’s prospects. And when E-shares start to trade at negative prices, it is time for the regulatory agencies to step in and take over the bank.
