Fiscal austerity: A solution looking for a problem

Since the release earlier this month of the paper by IMF economists Olivier Blanchard and Daniel Leigh, I've noticed a lot of comments on blogs and news websites suggesting that the IMF economists and their inability to properly measure the size of the fiscal multiplier earlier are to blame for making political leaders believe that fiscal austerity could be expansionary and for misleading them into enacting austerity measures within their respective nations.

That's nonsense.  As if the decision to go down the road of austerity depended on a technical detail such as the potency of the fiscal multiplier.  Such a statement is as implausible as suggesting that some of the ill-advised military interventions in the Middle East during the last decade would have been prevented had those leaders who decided to enter those wars had been provided better intelligence.

Those looking to blame someone for the current disaster created by fiscal austerity should instead turn to the real culprits, the politicians themselves, as well as their horde of political aides who recommended a course of action that flies in the face of both common sense and empirical evidence.

As I discussed in an earlier post, the case against expansionary austerity was well established even before nations decided to enact austerity measures.  And amazingly, the empirical evidence against expansionary fiscal austerity stems from one of the most highly circulated economics papers of 2009, which, ironically, was branded as supporting the case for expansionary fiscal austerity.

This paper is the study by Alberto Alesina and Sylvia Ardagna, which found that the combination of austerity and growth occurred in 25 percent of the relevant episodes recorded by the OECD between 1970 and 2007 (2009, Data Appendix:Table A2).

In other words, the study demonstrated that the odds of successfully reducing public debt levels and achieving increased growth through austerity were 1 in 4.  As far as empirical support in favor of expansionary fiscal austerity goes, that's pretty weak.  With such information available, going ahead with austerity was tantamount to someone deciding to intentionally leave their umbrella at home knowing that there is a 75 percent chance of rain that day.  So much for the theory of the rational decision-maker!

And now economists are to blame?

The bottom line is that the disaster of austerity is not about economists getting it wrong.  Rather, it is a typical example of a policy-making failure: policymakers making decisions without regard for the facts.  But, more importantly, fiscal austerity was a prepackaged "solution to a problem" that fits with today's dominant policy-making ideology, which holds that governments have little or no purpose other than catering to financial interests and leaving the path clear for free-market actors to find solutions to every problem facing society.

To conclude, fiscal austerity is simply another example of a "solution looking for a problem", an empty and empirically ineffectual idea with no clear rationale other than giving the appearance that "something is being done".  In this sense, fiscal austerity joins the list of other well-known solutions looking for problems that have been tried and failed in the last thirty years such as deregulation, privatization, supply-side economics and so on.

Evsey Domar's "On Deficits and Debt": A survival guide for making sense of today's economic challenges

As I look back to 2012, I'm reminded about how relevant the work of economist Evsey Domar, the late Professor of Economics at MIT and previously a Federal Reserve staff economist, is for making sense of the predicament facing the US and the world economies today.  Three news stories during the last year provided a good backdrop for presenting Domar’s views on public debt, budget deficits and economic growth.

First, there was the surprising about face during the summer months when European leaders switched from advocating austerity to voicing their support for actions that promote growth.  Professor Domar would have most likely approved of this change of heart by Europe’s ruling elite given that, many decades ago, Domar authored “The Burden of the Debt and National Income” (1944), a paper which argues that “the problem of the burden of the debt is a problem of achieving a growing national income” rather than one associated with the size of the budget deficit or national debt.

E. Domar

Specifically, in his paper, Domar demonstrated that, in the long run, the ratio of debt to GDP will gradually approach the ratio of the fraction of GDP borrowed each year to the rate of growth of GDP.  So, for instance, the US federal government borrowed approximately 7 percent of GDP in 2012.  If the borrowing continued at the same rate and the GDP (in money terms) grows at 2 percent per year, the ratio of debt to GDP will approach 3.5; with a 3 percent growth, it will be 2.3.

Thus, Domar showed that "less attention should be devoted to the problem of the debt and more to finding ways of achieving a growing national income" (1945:415)

According to Domar, attempting to reduce the public debt by cutting government expenditures (thus removing a significant source of income and growth from the economy) is largely self-defeating and exactly the wrong course of action if undertaken when the economy is struggling.

Then, in the fall, there was the debate among economists and bloggers about the intergenerational burden of the public debt.  Had he been around, Professor Domar would have probably been disappointed to learn that issues addressed (and, for many, put to rest) decades ago are still being debated.

And now we're facing the so-called ‘fiscal cliff’, a metaphor depicting the slowdown facing the US economy as a result of the expiry of tax breaks enacted at a time when the US federal fiscal budget situation was in better shape.  In the face of such a situation, Domar would have understood that the last thing policymakers should do when the economy is weak is to increase taxes which take away purchasing power from the economy.

As we enter a New Year, it is worth remembering Domar’s views on these and other related issues.  And nowhere are these matters best addressed than in his short, three-page article “On Deficits and Debt” published in 1993.  In this article, Domar challenges many of the widely held beliefs about debt and deficits. 

First, the article begins by taking on the popular view that considers the US federal government debt as analogous to household debt:

Our old puritanical injunctions against running into debt remain valid when applied to a private person. He or she can disregard them only at his or her peril.  A large corporation has more leeway: it can borrow by issuing bonds, and replace them with new ones when they fall due. If many large corporations simultaneously decided to pay off their debts, our economy would collapse: it is based on credit, the inverse of debt. Still any corporation, however large can go bankrupt...But, the Federal government is in a class by itself: so long as its debt is expressed in dollars (which fortunately is the case), it can always print as many dollars as it needs to pay the interest, though nowadays it would issue bonds, sell them in the market and, if necessary, have the Federal Reserve repurchase them. The Federal government, the creator of the Federal Reserve System, is its own banker.

Then, Domar describes the merits of a budget deficit:

By definition, a budget deficit means that the government spends more money then it receives, or, in other words, that it creates more purchasing power by its expenditures than it destroys through taxes.  Is this good or bad? It depends. If the economy is working to capacity, the creation of extra purchasing power will do little good and much harm: it will cause an inflation, which is easy to start and hard to stop. But when the economy has plenty of unused resources, the additional purchasing power is welcome. At such a time, we should rebuild our physical infrastructure, improve our education, health, and environment, and intensify our scientific and industrial research efforts, without raising taxes and without reducing or eliminating other needed services, always keeping a watchful eye on economic barometers to make sure that we do not overdo it.

All this sounds nice and easy, perhaps too easy to avoid suspicion. Are we to get something for nothing, as the old saying goes? Is there such a thing as a free lunch, after all? The offer of a free lunch is strictly temporary; it lasts only so long as unused resources, and particularly unemployed labor, are available, because they can be put to use with little, if any, social cost. But one they are gone government expenditures, however, desirable, must be matched with revenue.

Later in the article, Domar explains that the true burden of the national debt is distributional in that it involves a transfer of resources from one group to another group within the economy:

Some early proponents of fiscal policy argued that the size of the debt and of interest payments on it are not important because “ we owe it to ourselves”...There is some truth in this argument, but it should not be exaggerated. Even if all the Federal bonds were owned by Americans and all interest on the debt received by them, problems created by the existence of a large debt and by the need to transfer [billions of dollars] from the taxpayers to the bondholders would remain...

On the other hand, this does not mean that the...interest paid on the debt represents a net loss to the country...[T]hat interest go to other Americans, directly or not and that much of it is subject to Federal income taxes. President Eisenhower, who disliked deficits and debts, is reported to have said, shortly before he left the White House, that every American baby born at the time carried on its neck a tag indicating its share of the Federal debt. Perhaps it did; but it must have also borne a second tag showing its share of the value of the Federal bonds.

The article then presents some interesting views about whether the country’s ratio of debt to GDP is an appropriate indicator of the state of the economy:

Does the ratio of the debt to GNP matter? Yes, it does. Other things being equal, I would prefer a smaller rather than larger ratio...Other things are not equal. There are times and conditions calling for a deficit. Without it, unemployment may rise and the GNP may fall, thus raising, rather than lowering the debt burden.

The article concludes with a comment on how to best address the “debt problem”:

The proper solution of the debt problem lies not in tying ourselves into a financial straight-jacket, but in achieving faster growth of the GNP, a result which is, of course, desirable by itself. To the Republican and other politicians who are hell-bent on reducing the deficit and even repaying the debt, I would like to address a very short and simple question: Why? Are we suffering from an excess of purchasing power now?

As we head into the New Year and get ready to face many of the same concerns as in 2012, I think it would be a good idea to keep in mind these points.

On that note, I wish all readers of this blog a very Happy New Year!

UPDATE: The third paragraph was revised on January 12, 2013.  It originally indicated that Domar demonstrated in his 1944 paper that the ratio of deficit to GDP would equal the ratio of the fraction of GDP borrowed each year to the rate of growth of the economy.  Rather, Domar focused on the ratio of debt to GDP.  I also added a subsequent paragraph (after paragraph 3) which includes a reference to Domar's article "The Burden of the Debt: A Rejoinder" (1945).

Old Keynesian themes in Modern Monetary Theory

Readers of this blog know I'm generally supportive of the views espoused by proponents of Modern Monetary Theory (MMT). The reasons are fairly simple. First, MMT considers unemployment to be an important problem that must be quickly and effectively addressed by the government authorities.  I agree with that.  Also, MMT makes a good case on the important role of fiscal policy in ensuring stable and equitable economic growth.  Again, I agree with that.

But there is another reason I'm generally in agreement with MMT on many issues.  This has to do with the fact that MMT builds on some pretty solid economic thinking, much of which was well understood and accepted by earlier generations of Keynesian economists.  As someone who has a lot of respect for and who finds much insight from this earlier Keynesian tradition, I'm quite pleased to see MMT, a more recent school of thought, disseminate these views.

I was reminded of some of these - let's call them - "Old Keynesian" tenets in a recent blog post by Paul Krugman, in which he discusses a trifecta of issues relating to (1) the benefits of monetary sovereignty (i.e., where a nation issues and uses its own currency), (2) the debate on the supposedly inflationary nature of deficit spending financed via money creation or bond issuance and (3) the recent controversy regarding the potentially expansionary consequences of a "loss of confidence" in US government bonds by international investors .

The first of these views concerns monetary sovereignty, a central MMT theme.  This was also a well understood concept by earlier Keynesian economists.  For instance, monetary sovereignty was a key aspect highlighted in the work of economist Robert Eisner, who brilliantly described in his book The Misunderstood Economy (1994:74) why the US greatly benefits from being a currency issuing nation:

[One] point that is widely misunderstood or unrecognized is that this debt, relatively small as it is, is all owed in its own currency, US dollars.  We pay interest and principal in US dollars.  And our Treasury and Federal Reserve can always create all the dollars we need.  One may object that such money creation or the monetization of the interest-bearing debt may have undesirable consequences, particularly greater inflationary pressure.  But it may also have the desirable effect of stimulating the US economy if that is in order. In any event, the fact that US debt held by foreigners is virtually all denominated in US dollars rules out the possibility of unvoluntary default on US government obligations.

We are not in the position of many third world or other debtor nations that sadly had obligations in foreign currencies, frequently the US dollars.  The only way they could service their debt was to obtain foreign currencies. [...]

The "world's greatest debtor nation" gave the American public visions of the US going bankrupt.  Since the debt was essentially in our currency, however, this made no sense.  We could "print" out own money to pay it off or, in more sophisticated fashion, have the Federal Reserve create the money. (1994:74)

Several other Keynesian economists also held similar views, including economist Lorie Tarshis who emphasized this point in Elements of Economics (1947), the first Keynesian textbook to be published in the US.

Secondly, concerning the ever-lasting debate on the supposedly inflationary nature of deficit spending financed via money creation or bond issuance, MMT considers that the latter should be viewed as more inflationary than the former since the interest payments paid by government on its debt results in a greater expansion in the money supply (in the long run) than if the deficit is financed by money creation.

On this point, it may be instructive to recall that economists Alan Blinder and Robert Solow demonstrated long ago that the "potency" of deficit spending via money creation or bond issuance is not strictly related to the manner of financing.  In fact, Blinder and Solow demonstrate in "Analytical Foundations of Public Finance" (1974) that deficit spending financed via issuance of bonds has under normal, steady-state equilibrium conditions a greater fiscal multiplier than deficit spending via monetary financing in the long run:

When we correct an oversight committed by almost all previous users of the government budget constraint, a still more odd result emerges.  The error has been to ignore the fact that interest payments on outstanding government bonds are another expenditure item in the budgetary accounts. [...]

Under a policy of strict monetary financing, [in a stable system, the long-run government expenditure multiplier is simply the reciprocal of the marginal propensity to tax].  But the issuance of new bonds means a greater multiplier in the long run. (1974:50). (original emphasis)

Finally, as for Krugman's contention that a loss of confidence in US government bonds by investors may have potentially expansionary consequences for the US economy, economist Bill Vickrey presented a similar argument in his article entitled "Fifteen Fatal Fallacies of Financial Fundamentalism" (1996).  On whether a sell-off of US government bonds by foreign investors would have a detrimental effect on the US economy, Vickrey suggested the following:

It is not intended that the domestic government debt should be held in any large quantity by foreigners.  But should foreigners wish to liquidate holdings of this debt or any other domestic assets, they can only do so as a whole by generating an export surplus, easing the domestic unemployment problem, releasing assets to supply the domestic demand, and making it possible to get along with smaller deficits and a less rapidly growing government debt.  The same thing happens if domestic investors turn to investing in foreign assets, thereby reducing their drain on the domestic asset supply.

All that to say that, in my opinion, both Paul Krugman and proponents of MMT stand on solid ground regarding these issues.

Joseph Stiglitz on low interest rates as the cause of the crisis

Joseph Stiglitz takes on the argument that low interest rates caused the subprime crisis. It appears to be an old clip but I'm adding it to the file.

And, as I've noted previously, Robert Shiller agrees with Stiglitz on this.

Similarly, Barry Eichengreen also makes a great point when he argues that it's not only borrowers' frenzy for easy credit that's to blame for these types of problems. This is what Eichengreen has to say about who's at fault for the current European mess:

I’m not too big on the language of culpability. But it takes two to tango. For every reckless borrower there is a reckless lender. The Greeks may have borrowed too much, but someone lent them all that money. German banks and those who regulated them clearly played some role in the crisis.

See here for a more detailed analysis on the role of low interest rates during the lead up to the US subprime crisis.

Myths about the burden of the welfare state: Insights from Harold Wilensky's new book

It's not uncommon these days to hear that the problems affecting the public finances of European nations are linked to the high welfare standards that are characteristic of European public administration.  According to this view, the cost of welfare programs, including social security and other forms of government-protected minimum standards, are simply too expensive and must be cut dramatically if Euro countries such as Greece, Spain and Portugal are to "regain control" of their public finances.

A related claim also suggests that the high level of taxation required to support welfare state systems stifles growth and undermines a nation's commercial competitiveness.  Accordingly, cutting social programs is viewed as a necessary first step toward lowering corporate tax rates and, ultimately, attracting businesses and promoting growth.  One commentator recently summed up this view as follows: "To thrive, Euro countries must cut the welfare state".

In my opinion, there are several problems with this line of reasoning.  The first is that viewing the European sovereign debt crisis as a consequence of the degree of generosity of welfare state policies completely disregards the fact that several Europeans nations with elaborate welfare systems are not suffering the same problems as, for instance, Greece and Spain.  Kurt Huebner has summarized the problem of linking the European debt default crisis to the costs of welfare state entitlements succinctly in a recent policy note:

If too high entitlements, in other words high welfare state standards, have caused the sovereign debt default crises, we would expect that societies with the highest and most generous welfare states would be top-ranked in the group of sovereign debt default economies. According to general prejudice this would be Sweden, Denmark, Norway, Finland and Germany, Austria and the Netherlands. The last time I checked nearly all of those economies were ranked in the top – but in the group of economic high-achievers and not high debtors. In other words: making a causal link between sovereign debt crises and welfare state entitlements is not confirmed by empirical data.

As for the claim that the high levels of taxation that is required to support welfare state systems is detrimental to economic growth, this too is unfounded.  In a recent blog post, Martin Wolf refuted the argument that lower taxes are the principal route toward better economic performance.  On the contrary, Wolf demonstrates that, not only are today’s most solvent countries highly taxed, but also that the level of taxation has no incidence on economic growth.  For this reason, Wolf suggests that the current focus among policymakers and commentators on reducing the tax burden is misguided:

Indeed, among the eurozone countries shown, crisis-hit Ireland, Spain and Italy had relatively low average tax rates. (They also had fiscal surpluses or negligible fiscal deficits, prior to the crisis. But that is a topic for another occasion.) The heavily taxed eurozone countries on the right hand side of the chart (from Germany on up) are all now relatively crisis-free.

The conclusion to be drawn is that a tax burden (within the range of 30 per cent to 55 per cent of GDP) tells one nothing about a country’s economic performance. It is far more a reflection of different social preferences about the role of the state. What matters far more are culture, quality of institutions, including law, levels of education, quality of businesses, openness to trade, strength of competition and so forth.

But what about the impact of welfare policies as a whole on a nation's economic performance?  Surely, one would assume that high welfare standards would be a net cost to the economy and society?  Again, as with the claim that a high tax burden is detrimental to growth, this too is a misguided assumption.

The most comprehensive explanation of why the welfare state is not a drag on economic performance is found in the work of the late Harold Wilensky, Professor Emeritus of Political Science at UCLA, Berkeley.  Wilensky's most recent book entitled American Political Economy in Global Perspective (2012) provides a highly detailed and up-to-date analysis on the political economy of the welfare state.

In this book, Wilensky presents findings stemming from over 40 years of in-depth research on 19 rich democracies that, among other things, support the view that modern welfare policies do not have adverse effects on productivity and national income.  The book points to empirical evidence that supports this conclusion and lays out in a clear and convincing manner the argument that welfare systems are not a drag on economic performance (2012:7-14; 46-55). 

According to Wilensky, there are two main reasons why the welfare state is not detrimental to a nation's economy.  First, Wilensky argues that many sectors of social policy are simply productivity enhancing.  The following excerpt from the book summarizes this point quite well:

Mass access to medical care and health education via schools, clinics, and child care facilities reduces long-term medical costs and in some measure enhances real health and lifetime productivity; preventative occupational health and safety programs in the workplace reduce absenteeism and turnover and other labor costs; active labor market policies supplement and in some countries reduce reliance on passive unemployment insurance and public assistance and improve the quality of labor; innovative family policies reduce the cost of both mayhem and poverty, they also reduce income inequality and gender inequality, which are a drag on economic growth.  These are substantial offsets for the costs of welfare-state benefits to the nonworking poor, handicapped, and the aged.  The net economic effect of all the programs labeled the "welfare state" is therefore either positive (before 1974) or neutral (since 1974). (Wilensky, 2012:6)

As for the second explanation of why high welfare standards are not detrimental to economic performance, Wilensky argues that nations with highly developed welfare state systems are also nations with institutional structures and legal frameworks that foster the habit of consensual bargaining among the government, businesses, unions, interest groups and other social partners, whether it be through public institutions (e.g., legislative assemblies, intergovernmental relations) or private institutions  (e.g., governance boards, conflict resolution committees).  More specifically, nations with these types of institutional structures and bargaining arrangements in place (e.g., Norway, Sweden, Finland, Denmark, Netherlands) promote coalition-building among political and societal groups, as well as effective labor relations.  In addition, these institutional structures and bargaining arrangements foment a politics of moderation that minimizes confrontation between social actors, as well as reduces both policy paralysis (i.e., inaction by government even though there is strong support for certain policies by citizens and dominant social actors) and political brinkmanship between partisan groups.

In sum, nations with consensual bargaining arrangements in place encourage the development of public policies that are more reflective of the aspirations of the electorate and, as a consequence, that are less apt to fall prey to polarizing partisanship or result in costly citizen backlash and/or rollback, as is common in more confrontational democracies such as the US (e.g., tax-welfare backlash).

According to Wilensky, the most significant economic benefit flowing from this consensual form of political bargaining is that it facilitates productive trade-offs among the government, political parties, businesses and unions, many of which have positive impacts on productivity and economic performance.  The trade-offs favorable to good economic performance and typical of consensual democracies include the following:

• Labor embraces restraint on nominal wages in return for social security and related programs based on social rights and modest increases in real wages;
• Employers provide job protection in return for wage restraint, labor peace and sometimes tax concessions (e.g., lower taxes on corporations and capital gains);
• Employers provide participatory democracy in the workplace or community in return for labor peace and wage constraint;
• In return for all of the above, the government improves its tax-extraction capacity (i.e., capacity to increase taxation with minimal backlash from public), thus enabling it to offer more generous and popular social programs;
• Faced with strong unions and with the habit of making such trade-offs, management tends to cooperate with labor in return for the implementation of a wide range of government policies, including less intrusive regulations and more effective implementation of laws and executive orders. (Wilensky, 2012:46-49).

In addition to these trade-offs, Wilensky points out that consensual democracies benefit from lower strike rates, a higher rate of gross fixed capital investment and wage restraint during economic shock periods (2012:51).  According to Wilensky, the higher rate of capital investment and lower strike rate are the main causes of good economic performance for these nations.  Also, these nations benefit from less confrontation between social and political actors and strong countervailing sources of consensus where, for instance, the dominant influence of big business is matched by the power of big labor.  Finally, as a result of the greater degree of cooperation that exists between social partners in consensual nations, policy paralysis is more easily overcome and economic shocks are more quickly and effectively addressed and mitigated.

Now, I should emphasize that Wilensky is not suggesting that nations with consensual bargaining arrangements have stronger economies than nations with more "confrontational" bargaining arrangements (e.g., US, Canada, UK, etc).  On the contrary, Wilensky makes it clear that during the last four decades there has been "two roads" to good economic performance; nations with consensual bargaining arrangements (i.e., "high road" strategy) and nations with more confrontational bargaining arrangements (i.e., "low road" strategy) have performed equally well when examined from a purely economic standpoint.  The difference is that nations that have adopted the metaphorical "high road" do much better in terms of social and political performance (e.g., income and gender inequality, health, job security and education).  In other words, according to Wilensky,

[e]ither [road] can at various times and places result in good economic performance.  The sharp contrasts appear in social and political performance.  The choice is a matter of one's values. (Wilensky, 2012:190).

Before concluding, I should address one common objection that is often made by critics of the view presented above, which is that recent global developments such as increased immigration, international competition, the spread of multinational corporations (MNCs), and the deregulation of labor markets, to name but a few, pose significant challenges to the viability of the consensual bargaining model of governance and undermine the economic base that enables the trade-offs above to materialize.  In other words, the critique suggests that this model is outdated and no longer adapted to the modern world economy.  However, according to Wilensky, such developments have only had a moderate to small influence on consensual bargaining.  For instance, on the impact of MNCs, Wilensky notes that there is little evidence that MNCs have undermined the nation's capacity to accommodate the conflicting interest of social partners by means of consensual bargaining.

That said, Wilensky argues that there is one recent development that does threaten the survival of consensus-enabling arrangements and institutional structures that help sustain effective welfare state systems: the increasing power and ideology of central banks and the internationalization of finance.  Wilensky's view on this issue is highlighted in the following excerpt:

Perhaps one recent trend does undermine the capacity of modern democracies to shape their economic destinies: unregulated internationalization of finance and the increasing independence of central banks, a clear threat to collaborative relations among labor, industry, and the state and to flexible use of fiscal policy (taxes and spending).  Reinforcing this trend is the flow of recently ascendant American economic doctrines across national boundaries: a blend of 19th century liberalism (unmodified free markets, private property, minimum government), Reaganomics, and monetarist ideology.  This was the ideological base for the deregulation of the financial sector at the root of the meltdown and Great Recession. (2012:151) (my emphasis)

A word on the Eurozone crisis and the need for a countervailing force to the ECB

Although American Political Economy in Global Perspective does not address the current European sovereign debt crisis, my impression is that Wilensky would have given preference to a solution that would not only directly address the financial problem facing the periphery Euro nations (either through the creation of "Eurobonds" or the ECB purchase of periphery nation debt) but also promote the emergence of a countervailing force that would match the influence of the ECB.

In my view, two sets of proposals could help to achieve such a result, namely, the creation of stronger EU institutions (including a democratically elected EU president, see Charles Goodhart's recommendations here)*, as well as the proposal to implement European-wide wage-setting (see Andrew Watt's article here), a proposal that I think could give rise to a stronger, more centralized labor presence at the EU level.

Here are the relevant sections of the book relating to the concept of countervailing power and central bank independence and influence:

The German labor movement for decades remained a major countervailing force to the Bundesbank...[T]he postwar record of low inflation with only medium unemployment is a product not only of the Bundesbank's autonomy but of a labor movement that has traded off wage restraint and industrial peace for social benefits and worker participation.[...] The consensual bargaining between labor, government, and industry eases the Bundesbank's task of controlling inflation without greatly reducing employment.  The ascendance of the European Central Bank, however, changed all that.[...] (Wilensky, 2012:128)

That several of the countries whose central banks had limited autonomy before 1990 (Japan, Austria, Norway, or Belgium, 1965-1974, 1985-1989) outperformed countries with more independent central banks (Canada, Netherlands, Denmark, or the US before 1980) should give pause to those who adopted the "Bundesbank model" for the European Central Bank without the German labor, management, state, political, education and training and other institutions that made it work.  Unfortunately, the European Union has neither the offsetting institutions to constrain such a bank's behavior nor the European-wide welfare state and job creation antidotes to its strong deflationary medicine. (Wilensky, 2012:132) (my emphasis)

* Paul McCulley has also suggested that the ECB president "needs a boss" to whom he or she would be directly accountable. I very much agree.

The myth of the "global savings glut": Excessive risk-taking caused the crisis, not excess savings

Several speeches by central bank officials these days contain statements describing the need to eliminate the so-called global imbalances (the notion that large trade deficits and trade surpluses in different parts of the world are unsustainable).

Of course, re-balancing trade flows would certainly be a positive development, as it would help to unlock the grip that large surplus countries have on world production and enable other countries to more fully partake in the global economy.  Such a re-balancing might even trigger a dispersion of manufacturing and other commercial activities away from China and other surplus countries toward other emerging markets and, hopefully, back to developing countries.

From the standpoint of global fairness and economic development, the need to re-balance is a justified, sensible proposition.

Also, many people (and policymakers) seem to think that a re-balancing is necessary in order to prevent another financial crisis from occurring. At the heart of this belief lies the idea that it was the savings of countries running large current account surpluses (read China) that brought down US interest rates and led to the credit boom that caused the crisis. This is the story of the "global savings glut", as Ben Bernanke depicts it. In my view, the story makes for an interesting theory; however, according to the facts, the story is closer to myth than reality.

I've already addressed here the argument suggesting that low interest rates were responsible for the crisis. However, there are several other reasons to doubt the global savings glut story, many of which are found in this paper by Claudio Borio and Piti Disyatat of the Bank for International Settlement (BIS) entitled "Global imbalances and the financial crisis: Link or no link?". In the paper, Borio and Disyatat present seven key inconsistencies associated with the claim that savings from China and other countries running current account surpluses had a role in causing the crisis (p. 4).

First, the authors question whether there is a strong link between current account balances and US dollar long-term interest rates. For instance, the paper shows that, while long-term interest rates were increasing between 2005 and 2007, there was no apparent decrease in the US current account deficit.

Second, the authors note that the depreciation of the US dollar during the last decade is inconsistent with the claim that there was increasing demand for US assets from non-residents.

Third, the authors present evidence demonstrating that the link between the US current account deficit and global savings isn't as strong as commonly suggested. For instance, Borio and Disyatat show that, while the deficit began its deterioration in the early 1990s, the world savings rate actually trended downward to the end of 2003. Also, the paper shows that, while the savings rate in emerging markets has been increasing since 2006, the US current account deficit has tended to stabilize or narrow.

Fourth, the authors show that real world long-term interest rates have trended downward since the early 1990s, irrespective of changes in the global savings rate.

Fifth, the authors note that the rise in the savings rate of emerging markets is inconsistent with the strong growth that occurred between 2003 and 2007. If anything, the authors argue, the rise in savings should have instead depressed aggregate demand and slowed global growth.

Sixth, Borio and Disyatat argue that credit-fueled growth was not associated solely with deficit countries. Countries with surpluses, such as Brazil and India, have all had their bouts of credit booms recently.

Lastly, the authors point out that the countries viewed as responsible for the crisis (read again China) were those least affected by the crisis.

While all seven of these explanations are meant to refute the hypothesis of the global savings glut, it is the last two that provide the biggest clues for understanding what really caused the crisis. According to Borio and Disyatat, it's not the large current account deficits but rather the increasing gross capital flows since the 1990s that are to blame. Conceptually, the authors object to the focus on current account balances as an explanatory variable because it fails:

...to distinguish sufficiently clearly between saving and financing. Saving, as defined in the national accounts, is simply income (output) not consumed; financing, a cash-flow concept, is access to purchasing power in the form of an accepted settlement medium (money), including through borrowing. Investment, and expenditures more generally, require financing, not saving. The financial crisis reflected disruptions in financing channels, in borrowing and lending patterns, about which saving and investment flows are largely silent. (p. 1) (original emphasis)

In other words, the problem with using current account statistics, the authors claim, is that they capture the net financial flows that arise from trade in real goods and services but exclude the underlying changes in gross flows and their contributions to existing stocks, including those transactions relating to trade in financial assets consisting of the overwhelming majority of international financial activity. Also, the current account is silent about the extent to which domestic investments are financed from abroad.

Borio and Disyatat demonstrate these points by showing how gross capital flows rose from approximately 5 percent of world GDP in 1998 to over 20 percent in 2007, with the bulk of this expansion reflected in flows between advanced economies despite a decline in their share of world trade (p. 13).

Also, the authors show that the most important source of capital inflows into the US before the crisis originated in Europe, not emerging markets (p. 15). Finally, the paper shows the extent to which European banks were prominent in global banking during the last decade:

Since 2000, the outstanding stock of banks’ foreign claims grew from $10 trillion to a peak of around $34 trillion by end-2007, an expansion that is striking even when scaled by global GDP [...]. European banks accounted for a large fraction of this increase. (p. 16)

As a result, Borio and Disyatat argue that the causes of the financial crisis cannot be properly understood by looking at changes in national savings rates or real economy indicators such as current account balances. The fact that these indicators do not capture the underlying trend toward increased risk-taking on the part of banks and their involvement in supporting the expansion in the US housing market make them meaningless for understanding the true causes of the crisis.

Instead, the authors conclude that a large part of the blame lies with the banks, as well as the inadequacy of the financial system's regulatory regime and its inability to prevent excessive risk-taking and the development of credit and asset price booms.
