Science with very few (if any) data
Doing statistical analysis on a sample of size 1 is either a very frustrating or a very liberating exercise. The academic discipline known as history falls into that category. Most applied social science, including applied economics, does too. Applied economists use means fair and foul to try to escape from the reality that economics is not a discipline where controlled experiments are possible. The situation that an economically relevant problem can be studied by means of a control group and a treatment group that are identical as regards all but one external or exogenous driver, whose influence can as a result be isolated, identified and measured, does not arise in practice.

Saturday, August 1, my family will wing its way, DV, to Boston, MA. From there we will trek on to Martha’s Vineyard to spend the month of August doing nothing in particular. The combination of bad airport novels, adequate supplies of white wine (including, tell it not in Gath, vino verde) and the nearness of lots of family I don’t see enough of should enable me to recharge the nigh-depleted batteries. Safe and sheltered in the company of other effete liberals and pointy-headed intellectuals, I hope to have the time to finally write the bad book (tentatively titled ‘Oi Oikonomiks!’) I have promised my agent. This blog will fall silent (not before time, I can hear you mutter) until September.
The only blight on the landscape of this holiday is that, once again, a US presidential family has decided to vacation on Martha’s Vineyard during the month of August. From earlier visitations by the Clintons, I know that the arrival of the presidential hordes on the Vineyard represent a massive negative externality for all those who go there in pursuit of the same thing the president and his family seek: peace and quiet. Whether the local economy gets a temporary or lasting boost, I leave as a project for Econ 101.
The presidential party (or presidential court) that tags along on any presidential journey, let alone a temporary relocation involving the entire presidential nuclear family, looks and behaves like an occupying army. There are hundreds, if not thousands of persons charged with security, ranging from the secret service to the specially beefed-up state and local police forces.  Communications experts, specialist medical personnel, myriad advisers and countless other presidential hangers-on cause the Vineyard to sink at least a foot deeper into the sea. The carbon footprint is bigger than that of the yeti. The press corps and assorted other media camp out all over the island, competing with the presidential staff for first place in the hot air emission stakes. Roads are blocked. Traditional rights-of-way are suspended. Beaches become inaccessible.

In the current worldwide debate about greenhouse gas emissions, the political leaders of the new big polluters (NBPs, especially China and India) attempt to shift the burden of reducing the global flow of new carbon-dioxide-equivalent (CO2E) emissions to the old big polluters (OBPs, mainly Europe, North America and Japan) by claiming the moral high ground, based on two arguments: (1) we are poor, you are rich, and (2) it’s our turn now to pollute.
I will, in what follows, take as given the proposition that (1) global warming is a reality; (2) global warming is a bad thing and (3) that human-made CO2E emissions are a significant contributor to global warming. The science underlying these propositions is inevitably shaky - as has to be the case for any non-experimental science. Still I believe that, even if I don’t really know whether my grandchildren are more likely to swim down Oxford Street or to ice-skate down Oxford street, the cost of not doing something about man-made CO2E emissions if they are indeed as harmful as the Greenhouse Lobby argues is vastly greater than the cost of unnecessarily restricting CO2E emissions - an application of the precautionary principle, if you want.

The problem
Further expansionary monetary policy has become rather ineffective in the overdeveloped world because banks are capital-constrained rather than liquidity-constrained and because liquidity spreads in financial markets that bypass the banks have shrunk remarkably. Remaining spreads between sovereign debt instruments and assorted private securities of similar maturities can now be rationalised quite easily as reflecting just differential default risk. Until the banks get significantly more capital on their balance sheets, quantitative easing, credit easing and enhanced credit support are examples of pushing on a string.
The banks will take the liquidity offered and redeposit the bulk of it with the central bank again rather than lending it to the private sector or purchasing more risk financial instruments. Low official policy rates (and the expectation of the official policy rate being kept at a low level for a further significant period of time) will help recapitalise the banks. So will the quasi-fiscal subsidies most central banks have been channelling into the banking system through the favourable terms offered by the central banks to the private banks in their transactions, facilities etc., but such gradual recapitalisation through wide margins on low volumes of lending is slow and could lead to a re-run of Japan’s lost decade for much of the G7.
Further expansionary fiscal policy is likely to be ineffective in most of the G7 countries (possibly excepting Germany and Canada). This is, first,  because households are short of capital and overly indebted and, second, because any further increase in short-term fiscal deficits is likely to undermine confidence in the sustainability of the fiscal-financial-monetary programme of the state. Continue reading "Islamic finance principles to restore policy effectiveness"

Today’s guest blogger is Elena Panaritis, an expert in property rights, creating markets in illiquid real estate assets, and public sector management. She is also the author of Prosperity Unbound; Building Property Markets with Trust, which is definitely not one of those odious get-rich-quick-in-real-estate-without-capital-brains-or-effort books. Instead it is a get real book for social entrepreneurs about how to turn real estate possessions into socially productive, and indeed also privately profitable, capital.
This Crisis Demands Non-Traditional Solutions to Get to a Path of Quick Recovery
By Elena Panaritis
Two years after it began, there is now a coalescing of opinion about the causes of the U.S. financial crisis and what should be done to resolve it, yet there is a serious element missing both in the causation analysis as well as in the prescriptive solution. This crisis, which has infected the global economy so severely, is very much a non-traditional one that calls for a non-traditional solution. The impact in the United States so far has been worse than anything since the Great Depression: unemployment reached 9.5 percent in June, up from 7.8 percent in January, home prices were down 27% at the end of the first quarter from their 2006 peak, and 1.5 million homes were in foreclosure. After jumping by 30 percent in February, home foreclosure rates tapered off but are again on the rise. According to the New York Times, the loss in property value could total $500 billion. Continue reading "The real estate roots of the crisis in the US"

The Fed is in trouble. Obama administration proposals for enhancing the Fed’s supervisory and regulatory role and for assigning it new macro-prudential responsibilities and powers - effectively turning it into the nation’s systemic risk regulator - are meeting with strong and vocal opposition. The criticism is not just coming from the other agencies in the US financial sector regulatory and supervisory spaghetti bowl - agencies that would stand to lose power and influence or could be put out of business completely. The desire for stronger Congressional oversight of the Fed is no longer confined to a few libertarian fruitcakes, conspiracy theorists and old lefties. It is a mainstream view that the Fed has failed to foresee and prevent the crisis, that it has managed it ineffectively since it started, and that it has allowed itself to be used as a quasi-fiscal instrument of the US Treasury, by-passing Congressional control. Are any or all of these criticisms justified? Let’s ponder a few of them. Continue reading "What to do with the Fed"

California’s public finances are in many ways a microcosm of those of the US as a whole. Admittedly, the state government’s deficit is tiny compared to that of the federal government. The state of California has a budget deficit this year of $26.3bn (about 1.5% of state GDP, which was just over $1.8 trillion in 2007), on revenues of just $113bn. Its total outstanding stock of state debt is also small, with just $59bn in general debt, $8bn in bonds linked to securitised revenues and about $2bn in commercial paper. In contrast, the US federal government is about to run a budget deficit in the 13 to 14 percent of GDP range (that is, the federal deficit is about the size of the state of California’s GDP!).
California, like every US state, will be hit by federal deficit and by the manner in which this is eventually brought under control again, be it through tax increases, public spending cuts, inflation or sovereign default. The state deficit, and the manner of its eventual resolution, represents pain for Californians on top of the shared misery they will endure as a result of California’s contribution to the resolution of the unsustainability in the federal public finances.

Private insurance only works if there is risk. If the risk is eliminated, profitable insurance is impossible. This holds for health insurance as it holds for credit default swaps. When risk vanishes, insurance turns into redistribution. That’s a task for the state, whether through the tax payer or by mandated pooling in quasi-private insurance schemes of individuals with known heterogeneous health profiles.
The rise of genomics - the branch of genetics that studies organisms in terms of their full DNA sequences or genomes - will in the not too distant future kill off most private health insurance. That’s probably a good thing, for two reasons. First, because of asymmetric information, when there is risk and uncertainty about a person’s future health, health insurance markets are badly affected by adverse selection and moral hazard. Second, because the private health insurance industry is a monument to inefficiency everywhere and, especially in the US, a rent-seeking Leviathan whose ruthless lobbying efforts corrupt all it touches.

Like most authors, I tend to cringe when I read something I wrote more than a few years ago. But while engaging in some authorial auto-archeology recently when preparing the index for a new paper (after all, if I don’t cite myself, who will?), I was pleasantly surprised with a few bits from a paper I wrote in 1999 and published in 2000 in the Bank of England’s Quarterly Bulletin, titled “The new economy and the old monetary economics”.
The paper takes aim at the assertion, rampant in 1999, that the behaviour in recent years of the world economy, led by the United States, could only be understood by abandoning the old conventional wisdom and adopting a ‘New Paradigm’. Prominent among the structural transformations associated with the New Paradigm were the the following: increasing openness; financial innovation; lower global inflation; stronger competitive pressures; buoyant stock markets defying conventional valuation methods; a lower natural rate of unemployment; and a higher trend rate of growth of productivity.
I argue, first, that the New Paradigm has been over-hyped. “…Unfortunately, the ‘New Paradigm’ label has been much abused by professional hype merchants and peddlers of economic snake oil.”
Second, I argue that, to the extent that we can see a New Paradigm in action, its implications for monetary policy have often been misunderstood.
I was particularly pleased that I had written following about financial innovation: Continue reading "Harmful financial innovation"

Last week the Eurosystem performed a €442bn injection of one-year liquidity into the Euro Area banking system. They did this at the official policy rate - the Main refinancing operations (fixed rate) - of 1.00 percent, against the usual collateral accepted for Longer Term Financing Operations, effectively anything euro-denominated, not based on derivatives and rated at least BBB-. It was a fixed-rate tender, that is, the ECB was willing to meet any demand at the 1 percent interest rate, as long as eligible collateral was offered; 1121 banks participated in the operation.
You will not be surprised to hear that this was the largest one-day ECB/Eurosystem operation ever. Even more remarkable than its scale are the terms on which the one-year funds were made available. There can be no doubt that this operation represents both a subsidy and a gift from the Eurosystem to the banks that participated in the operation. I hope to clarify the distinction between a subsidy and a gift in what follows.
