It's the demand, stupid! The role of weak demand on productivity growth

I couldn't resist the title.

Last week I was invited to give a short talk on what I thought was the most pressing policy issue facing the world economy today.

So I presented the findings from a very interesting paper entitled "Explaining Slower Productivity Growth: The Role of Weak Demand Growth" by Someshwar Rao and Jiang Li.

The paper examines the link between demand and productivity growth in both Canada and OECD countries. This issue has been an interest of mine ever since I read these lines in a book by Alan Blinder several years ago:
Economic slack...discourages business investment because companies that cannot sell their wares see little reason to expand their capacity. In consequence, the nation gradually acquires a smaller, older, and less efficient capital stock. 
[A]lthough the state of the national is far from the only factor, who doubts that a booming economy provides a better atmosphere for inventiveness, innovation, and entrepreneurs than a stagnant one? As the cliché says, a rising tide raises all boats...From 1962 to 1973, our generally healthy economy experienced only one mild recession, an average unemployment rate of 4.7 percent, and productivity growth that averaged a brisk 2.6 percent per annum. [Between 1974 and the mid-1980s] the economy [was] frequently...out of sorts. We...suffered through two long recessions and one short one, with an average unemployment rate of 7.3 percent and a paltry average productivity growth rate of 1 percent. This association of high unemployment with low productivity growth is no coincidence. 
Surveying these concomitants of high unemployment -- lack of upward mobility for workers, sluggish investment, lackluster productivity growth -- suggests an ironic conclusion: the best way to practice supply-side economics may be to run the economy at peak levels of demand. (1986:36).
This still makes lots of sense to me.

Verdoorn's Law

During my talk I described the paper as lending support to the well-known findings of economist Petrus J. Verdoorn, who several decades ago published research showing a positive relationship between labour productivity growth and real output growth.

In retrospect, I probably shouldn't have discussed this since it led to a number of questions on Verdoorn and his research, which shifted the focus away from the paper and the real purpose of my talk, which was to drive home the point that there is considerable evidence that productivity growth shouldn't be viewed as solely a supply-side phenomenon.

Specifically, the paper supports the -- in my opinion, common sense -- view that a slowdown in domestic and external demand is detrimental to growth in labour productivity, real incomes and economic activity because of the negative impact of weaker demand on scale and scope of economies, formation of physical and human capital, innovation and entrepreneurial activity.

Here are the paper's main findings:
Our major findings is that 93 percent of the fall in average labour productivity growth between 1981-2000 and 2000-2012 can be attributed to the drop in real GDP growth between the two periods...In addition, our new empirical research shows that a slowdown in growth of domestic and external demand also impacts negatively some of the key drivers of productivity growth, such as, gross fixed capital formation, M&E investment (including ICTs) and R&D spending, thus leading to lower trend labour productivity. (2013:14)
I concluded my presentation by discussing some of the policy implications outlined by the paper's authors. At this point, I was hoping my comments would get the attention of the government policy analysts and economists in the audience.

First, I suggested that it would be prudent for governments to ensure that deficit and debt reduction measures are gradual in nature so that their negative impact on domestic demand would not be excessive.

Then, I explained that it's always a good idea for governments to spend on productivity-enhancing public investment, even during a period of economic slowdown, as it contributes to both today's demand as well as future productivity growth.

Moving past the 90 percent threshold: Focusing on growth

Now that the proposition of a 90 percent threshold (of public debt-to-GDP above which countries' economic growth would significantly slow) associated with the work of Carmen Reinhart and Ken Rogoff has been refuted, it's important that the debate now turn to the critical issue of how best to achieve growth moving forward.

On this point, one important aspect to keep in mind is that the uses toward which public debt is directed and the composition of public debt tend to have a significant impact on a country's economic growth.

A recent study by the IMF entitled "Public Debt and Growth" appears to support this view. The study, which examined the public debt dynamics in over 30 countries, found that, although the elasticity of growth with respect to public debt is -0.02, the elasticity of other variables that positively impacts growth offsets this number. For instance, as Iyanatul Islam has noted, the study shows that the elasticity of growth to initial years of schooling is above 2.0.

In other words, it's quite likely that public debt directed toward productive uses has the effect of supporting growth by cancelling out some of the negative effects associated with high public debt that impede growth.

These are the sort of issues policymakers should be discussing moving forward. I think it would go a long way to help us get out of the economic doldrums we're facing today.

Public investment and productivity growth: How to provide properly for the future

Just as I was thinking about the moral aspects of economic policy, here comes Paul Krugman with a fantastic commentary on how governments today are shortchanging future generations by not taking advantage of record low interest rates and not spending on productivity-enhancing public investments:
Fiscal policy is, indeed, a moral issue, and we should be ashamed of what we’re doing to the next generation’s economic prospects. But our sin involves investing too little, not borrowing too much — and the deficit scolds, for all their claims to have our children’s interests at heart, are actually the bad guys in this story. 
So true. This reminds me of something the late economist Robert Eisner wrote:
...balancing the budget at the expense of our public investment in the future is one way that we really borrow from our children - and never pay them back. (1996)
The reason for this is that the "deficit equals bad" crowd is completely oblivious to the fact that public investment adds to the stock of productive assets that help to enhance private sector productivity in the long run. And public spending on infrastructure, education, basic research and the development of new technology is essential to achieve the level of productivity necessary to improve our standard of living in the future.

And at a time when we are facing an aging population, increasing our future productivity growth should be a (if not the number one) priority.

A good explanation for this is provided by Francis Cavanaugh, former senior US Treasury Department economist and former CEO of the Federal Retirement Thrift Investment Board, who argues that
Significant productivity increases will be necessary as a diminished labor force is called on to support an expanded group of retirees. Without such increased production per worker, a shortage of goods will lead to price increases, and it is likely that the baby boomers will suffer a significant decline in the purchasing power of their retirement dollars. Inflation could soon decimate their retirement savings. That's the economic reality; if you're not working, you're dependent on the productivity of those who are. (1996)
In other words, the best protection against the potential losses that come with an aging population is to take measures today aimed at increasing the productivity growth of tomorrow. This should be the long term goal of policymakers right now.

So Prof. Krugman is right: contrary to what most politicians and commentators believe about how to improve our long-run prospect, slashing government spending is exactly the wrong thing to do at this time.

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.

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.
