Is a Love of Finance the Root of All Evil?

There is a syllogism that has gained currency just as financial markets have been devalued. And it goes something like: (i) finance is dangerous (ii) the economy is in danger (iii) finance must therefore be constrained. I regularly attend conferences and hear a panoply of dirigiste sentiment directed against the financial sector, arguing that not only that financial markets and banks been the root cause of the final crisis but that they must now be bound like Prometheus to a stone. Though such a conclusion is tempting, it may not be quite right.

The critiques are well known: financial markets underpriced risk, created excessive liquidity and leverage, unbundled exotic near-worthless debt instruments and at the limit, often via hedge funds, promised semi-permanent excess returns. All activities that rewarded participants on the upside and ended up having government support on the downside. The argument then is that faced with such a skew in returns, too many resources have been devoted to financial activity. It is said that banks and financial institutions have become too large both in absolute size because they cannot then be allowed to fail without creating systemic risk and relative to the size of the economies they service. Maybe.

Let us rehearse the arguments about why finance matters. Finance allows individuals and firms to disconnect in time and space their abilities to earn and their abilities to spend and hence concentrate on one or other at any particular moment. The advantages of specialisation are clear – everyone can benefit from the greater production of goods and services by allowing agents inter-temporal as well as geographical options to share resources. But we do know that the efficient allocation of funds from savers to borrowers is subject to severe informational constraints and also various temptations to renege: the avoidance of these problems requires significant regulation, institutional capability and investment in reputation-building. These kind of first order problems do not in general sort themselves out and it is possible even to write about the vast sweep of economic development itself in terms of the history of solutions, failed or otherwise, to these types of problems.

So we can expect that alongside the development of financial instruments we will have to re-write the book of rules and regulations every generation or so, as we moved from heavyweight capital controls in the immediate post-war era under Bretton Woods to an era of neo-liberalism running from the late 1970s to about now and hopefully beyond. And so let us not take the initial premise too far in that the problems with the global financial system are best solved by reducing the size of that system because it seems likely that at least some of the problems stem from its incompleteness rather than its dominance. Let me illustrate: it is entirely proper that capital flows from “impatient” countries to “patient” countries and at some real interest rate the deficits of the impatient must equal the surpluses of the patient. Over time the patient countries will then build up claims or assets against the debts of the impatient countries. Now let us suppose that the patient countries become wealthier, say as their productivity levels catch-up, and all this extra wealth is saved, global savings will then initially exceed investment and interest rates will have to fall to clear the global market for savings, encouraging the impatient to become more impatient and increase their overall level of indebtedness.

For impatient read the US and for patient read China. Under this equilibrium real rates are low and capital flows uphill from fast growing to mature economy. The problem here is that the extra savings are all being sent to the impatient, as there are limited vehicles for the patient to invest in their own economy. In a closed economy, the extra income would have to be channelled domestically and domestic growth would be stimulated in order to use the savings. And so by the same token, if there is an inadequate development of savings vehicles in the patient economies then these savings will tend to drive up the prices of existing assets, for example, US Treasuries which will be in short supply. This global excess demand for assets hence drives down real interest rates raising other asset prices in turn, for example housing, equity or real commodities.

It is thus the lack of financial development in emerging economies which arguably lies at the heart of the problem of this financial crisis and not, perversely, the excess of financial development. An example from the most recent IMF Article IV report from October 2006 for China suffices to illustrate the point, which reports that the foreign exchange rate market remains tightly managed, there seems to be little development of bond markets even at maturities of less than one-year and little or now availability of bonds in the 1-10 year maturity range and equity markets seem not to allow firms to access the market. Overall the IMF view was that the “limited role of capital markets in China…reflects the dominance of state banks in intermediation, but these markets are plagued with regulatory and governance problems”. Obviously a report form late 2006 may well be rather out of date but it does clearly illustrate the point about a lack of liquid assets in newly emerging economies at the high watermark period of so-called financial excesses.

So rather than shunning financial market development, global policies ought also to think more about deepening capital markets and encouraging the development of assets across the risk spectrum, particularly in parts of the world where surpluses are being generated. By helping the development of such assets, policy makers will help raise global real rates, help prevent the conditions under which asset price bubbles will develop and also help get various parts of the world onto more sustainable growth paths that are not reliant on the capacious appetites of Western-style consumption alone. And if as a consequence, we become a little more patient and they become a little more impatient, then we have all become a lot closer to each other, which is a rather pleasant thought.

Global Imbalances - The Basic Story

One of the root causes of the financial crisis has been the unnatural sight of capital flowing uphill, that is from poor to rich countries. In a famous calculation, Robert Lucas (1990, AER) showed that if a rich and poor country have equivalent production technologies and differ only in income per head, then because the amount of capital employed in the poorer country will be less than in the richer country, the marginal efficiency of capital must be higher in the poorer country and so attract capital. For example, latest EIU data suggests that Chinese PPP per capita income is around $5,000 and the US is $45,000 which implies (calculation available on request) that the rate of return on capital in the US should be around 3-4% of that in China and should mean that China runs a current account deficit financed by a US surplus. The reality has, of course, been the obverse with US recycling China’s capital flows.

Let us examine the basic problem. Global savings equal investment at a single world interest rate (absenting risk). Figure 1 draws the equilibrium for the two country world of China and the USA, given their savings and investment schedules. In a closed economy, US interest rates would clear the domestic market for saving above R* and output would be determined accordingly. But when we open up to capital flows at the world interest rate, R*, the US expands its investment demand relative to savings, running a deficit, and at those interest rates China generates a current account surplus. The surplus (deficit) in each year adds (reduces) to net foreign assets in each year in the creditor (debtor) country.

The counterpart of savings excess in China is excessive investment in the US - recall that this comprises both public and private investment. Is a small reduction in US demand (investment) the answer? Not necessarily. Even if demand falls sufficiently to eliminate the US current account deficit at stable world rates, R*, then China would still have excess savings. This excess would drive rates down from R* and lead to the re-mergence of a current account deficit, albeit with lower world rates and a lower level of global imbalances. Obviously with large enough falls in US demand you could get zero current account balances in both countries at very low R and low US demand. Perhaps this is the solution, as we stare at a global recession, that we are heading towards?


We can also consider a number of alternative solutions. For example, a shift up in Chinese demand to clear the surplus at R*, at the original equilibrium, will mean excess demand in the US continues and thus world rates R* will go higher and there will still be a Chinese surplus and a US deficit. Obviously again if Chinese demand shifts up even further we can have no capital flows but at significantly higher world interest rates and high world demand. This may not be the solution we are heading towards!

The problem with this diagram as far as I can see is that any R can lead to an initial equilibrium providing China is willing to lend (or borrow) and US is willing to borrow (or lend). And what we learn is that if we want to adjust to some different level or direction of capital flows is that if only one country adjusts the overall change in rates and output will be greater than if they both adjust somewhat.

So what is the constraint or target? It must be something to do with the equilibrium level of net foreign assets to GDP and flows from one country to another to meet that target. The US is a debtor nation, (at around 6-7% of global GDP) implying that its current demand will be met by saving from higher future income. In this scheme (and I do not know the actual numbers but according to the IMF’s WEO Emerging Asia is in credit by around 5% of global GDP) then China will be the creditor. But for the reasons given earlier China should probably be the net debtor and borrow from its higher future income. And so if we are to get to a situation when eventually China becomes a debtor so capital flows downhill (from rich to poor), this will imply the need for a surplus in the US and a deficit in China, which implies lower US demand, greater US savings, higher Chinese demand and lower Chinese savings. But we probably knew that!
