On the web: Lehman’s legacy, the Irish referendum on Lisbon, transatlantic trends and more…

– With the anniversary of Lehman Brother’s demise, the FT recalls the events of that fateful weekend last September. The NYT has reflections of three former Lehman employees, while a Guardian roundtable asks what lessons, if any, we’ve learned from the bank’s fall. Niall Ferguson, meanwhile, rails against those who argue “if only Lehman had been saved”. He suggests:

Like the executed British admiral in Voltaire’s famous phrase, Lehman had to die pour encourager les autres – to convince the other banks that they needed injections of public capital, and to convince the legislature to approve them.

– Sticking with matters financial and economic, Der Spiegel has an interview with the head of the IMF, Dominique Strauss-Kahn, on the Fund’s actions during the crisis and the potential for a new role for the institution going forward. Former MPC member, David Blanchflower, meanwhile, offers a telling insight into the inner workings of the Bank of England’s decision-making as financial meltdown ensued.

– Elsewhere, the WSJ reports on President Sarkozy’s call to broaden indicators of economic performance and social progress beyond traditional GDP, following the findings of the Stiglitz Commission. Richard Layard, expert on the economics of happiness, offers his take here, arguing that “[w]e desparately need a social norm in which the good of others figures more prominently in our personal goals”.

– Wolfgang Münchau, meanwhile, assesses the implications of an Irish  “No” vote in the upcoming referendum on the Lisbon Treaty.  “There is an intrinsic problem for the Yes campaign in Ireland”, he suggests, “which is that the core of the treaty was negotiated seven years ago. This is a pre-crisis treaty for a post-crisis world… If we had to reinvent the treaty from scratch, we would probably produce a very different text”.

– Finally, last week saw the German Marshall Fund of the US publish its Transatlantic Trends survey for 2009. Unsurprisingly, a majority of Europeans (77%) support Barack Obama’s foreign policy compared to the 2008 finding for George W. Bush (19%); though the “Obama bounce” was less keenly felt in Central and Eastern Europe than Western Europe. A multitude of other interesting stats – on attitudes to Russia, Afghanistan, Iran, the economic crisis, and climate change –  can be found here (pdf).

On the web: Bernanke’s reappointment, al-Megrahi’s release, foreign policy realism, the “perfect storm”, and more…

– With the news that President Obama has nominated Ben Bernanke for a second term, over at the New Republic Noam Scheiber assesses the merits of continuity at the Fed. Stephen Roach, meanwhile, examines the case against the incumbent chairman, arguing that Obama’s decision should open a “broader debate over the conduct and role of US monetary policy”.

– Taking us back to the depths of last September’s financial meltdown, Faisal Islam has some interesting insights into the collapse of Lehman Brothers as viewed from British shores.

– Elsewhere, debate continues apace about the rights and wrongs of releasing the Lockerbie bomber. Suggesting that “cock-up offers as convincing an explanation as conspiracy for the handling of Mr Megrahi’s release”, Philip Stephens argues that the decision highlights the “price of realism” in foreign policy.

– Speaking of which, in the latest edition of FP Magazine none other than Paul Wolfowitz assesses the realist credentials of President Obama; providing at once a telling insight into the mindset of a man at the heart of foreign policy making during the Bush years.

– Mark Easton’s BBC blog, meanwhile, takes a look at how the British government is looking to influence public behaviour in light of the Chief Scientist’s warning of a “perfect storm” of energy, food and water scarcity by 2030.

– Finally, as President Obama holidays on Martha’s Vineyard, the White House announces what he’ll be reading on the beach. Slate offers its take here.

21st century finance: too complex to exist?

As we push on through the recession, one thing that we haven’t seen enough of is solid original thinking about the causes of the crisis and what can be done to stop such a systemic disaster ever happening again. However Duncan Watts, writing in the Boston Globe, has a bold idea. Not only were banks to big to fail but the system as a whole is simply too complex to exist.

Rather than waiting until the next cascade is imminent, and then following the usual modus operandi of propping up the handful of firms that seem to pose the greatest threat, it may be time for a new approach: preventing the system from becoming overly complex in the first place.

It’s well known that few in the financial sector (let alone regulators) understood the instruments that were being used. Risk assessors refused to believe that a firm like Lehman Brothers could ever fall so easily and as a result, the consequences of such a collapse were not accounted for in risk models. In an ever more interlinked world, the danger of contagion effects means that everyone has an interest in the way the system works. If only a few people understand it, so much the worse for the rest of us.

An alternate approach is to deal with the problem before crises emerge. On a routine basis, regulators could review the largest and most connected firms in each industry, and ask themselves essentially the same question that crisis situations already force them to answer: “Would the sudden failure of this company generate intolerable knock-on effects for the wider economy?” If the answer is “yes,” the firm could be required to downsize, or shed business lines in an orderly manner until regulators are satisfied that it no longer poses a serious systemic risk. Correspondingly, proposed mergers and acquisitions could be reviewed for their potential to create an entity that could not then be permitted to fail… Perhaps what we need is an “anti-systemic risk” law that would aim to avert systemic risk before it is too late.

Watts concedes that this degree of intervention in the market is concerning, but one thing that everyone seems to agree on is that the era of market fundamentalism is over. If we’re willing to allow the state to intervene in bailing out failed banks, why not intervene to prevent them becoming unmanageable in the first place? Think of it as bonsai banking. As E.F. Schumacher said, ‘small is beautiful’.
