It is now some seven years since the financial crisis and nearly seven years since interest rates in the USA, the eurozone, the UK and elsewhere have been close to zero. But have these record low interest rates and the bouts of quantitative easing that have accompanied them resulted in higher or lower investment than would otherwise have been the case? There has been a big argument about that recently.
According to conventional economic theory, investment is inversely related to the rate of interest: the lower the rate of interest, the higher the level of investment. In other words, the demand-for-investment curve is downward sloping with respect to the rate of interest. It is true that in recent years investment has been low, but that, according to traditional theory, is the result of a leftward shift in demand thanks to low confidence, not to quantitative easing and low interest rates.
In a recent article, however, Michael Spence (of New York University and a 2001 Nobel Laureate) and Kevin Warsh (of Stanford University and a former Fed governor) challenge this conventional wisdom. 
According to them, QE and the accompanying low interest rates led to a rise in asset prices, including shares and property, rather than to investment in the real economy. The reasons, they argue, are that investors have seen good short-term returns on financial assets but much greater uncertainty over investment in physical capital. Returns to investment in physical capital tend to be much longer term; and in the post-financial crisis era, the long term is much less certain, especially if the Fed and other central banks start to raise interest rates again.
“We believe that QE has redirected capital from the real domestic economy to financial assets at home and abroad. In this environment, it is hard to criticize companies that choose ‘shareholder friendly’ share buybacks over investment in a new factory. But public policy shouldn’t bias investments to paper assets over investments in the real economy.”
This analysis has been challenged by several eminent economists, including Larry Summers, Harvard Economics professor and former Treasury Secretary. He criticises them for confusing correlation (low investment coinciding with low interest rates) with causation. As Summers states:
“This is a little like discovering a positive correlation between oncologists and cancer and asserting that this proves oncologists cause cancer. One would expect in a weak recovery that investment would be weak and monetary policy easy. Correlation does not prove causation. …If, as Spence and Warsh assert, QE has raised stock prices, this should tilt the balance toward real investment.”
Not surprisingly Spence and Warsh have an answer to this criticism. They maintain that their critique is less of low interest rates but rather of the form that QE has taken, which has directed new money into the purchase of financial assets. This then has driven further asset purchases, much of it by companies, despite high price/earnings ratios (i.e. high share prices relative to dividends). As they say:
“Economic theory might have something to learn from recent empirical data, and from promising new thinking in behavioral economics.”
Study the arguments of both sides and try to assess their validity, both theoretically and in the light of evidence.

First the IMF in its World Economic Outlook, then the European Commission in its Economic Forecasts (see also) and now the OECD in its Economic Outlook (see also) – all three organisations in the latest issues of their 6-monthly publications are predicting slower global economic growth than they did 6 months previously. This applies both to the current year and to 2016. The OECD’s forecast for global growth this year is now 2.9%, down from the 3.7% it was forecasting a year ago. Its latest growth forecast for 2016 is 3.3%, down from the 3.9% it was forecasting a year ago.
Various reasons are given for the gloomier outlook. These include: a dramatic slowdown in global trade growth; slowing economic growth in China and fears over structural weaknesses in China; falling commodity prices (linked to slowing demand but also as a result of increased supply); austerity policies as governments attempt to deal with the hangover of debt from the financial crisis of 2007/8; low investment leading to low rates of productivity growth despite technological progress; and general fears about low growth leading to low spending as people become more cautious about their future incomes.
The slowdown in trade growth (forecast to be just 2% in 2015) is perhaps the most worrying for future global growth. As Angel Gurría, OECD Secretary-General, states in his remarks at the launch of the latest OECD Economic Outlook:
‘Global trade, which was already growing slowly over the past few years, appears to have stagnated and even declined since late 2014, with the weakness centering increasingly on emerging markets, particularly China. This is deeply concerning as robust trade and global growth go hand in hand. In 2015 global trade is expected to grow by a disappointing 2%. Over the past five decades there have been only five other years in which trade growth has been 2% or less, all of which coincided with a marked downturn of global growth.’
So what policies should governments pursue to stimulate economic growth? According to Angel Gurría:
‘Short-term demand needs to be supported and structural reforms to be pursued with greater ambition than is currently the case. Three specific actions are key:
|
|
| • |
First, we need to resist and turn back rising protectionism. Trade strengthens competition and investment and revs up the “diffusion machine” – the spread of new technologies throughout the economy – which will ultimately lift productivity. |
| • |
Second, we need to step up structural reform efforts, which have weakened in recent years. And here, I mean the whole range of structural reforms – education, innovation, competition, labour and product market regulation, R&D, taxes, etc. |
| • |
Third, there is scope to adjust public spending towards investment. If done collectively by all countries, if the sector and projects chosen have high multipliers, and if combined with serious structural reforms, stronger public investment can give a boost to growth and employment and not increase the relative debt burden.’ |
On this third point, the OECD Economic Outlook argues that ‘the rationale for such investments is that they could help to push economies onto a higher growth path than might otherwise be the case, at a time when private investment growth remains modest.’
‘Collective action to increase public investment can be expected to boost the initial domestic multiplier effects from the stimulus, since private investment and exports in each economy will benefit from stronger demand in other economies. …the multiplier effects from an investment-led stimulus are likely to be a little larger than from other forms of fiscal stimulus, since the former also has small, but positive, supply-side effects.
In other words, the OECD is calling for a relaxation of austerity policies, with public investment being used to provide a stimulus to growth. The higher growth will then lead to increased potential output, as well as actual output, and an increase in tax revenues.
These policy recommendations are very much in line with those of the IMF.

This rather strange question has been central to a storm that has been brewing between various celebrity chefs, including Jamie Oliver and Hugh Fearnley-Whittingstall, and the supermarkets. Supermarkets say that consumers don’t want irregular shaped vegetables, such as carrots, parsnips and potatoes. ‘Nonsense’, say their critics.
At the centre of the storm are the farmers, who find a large proportion of their vegetables are rejected by the supermarkets. And these are vegetables which are not damaged or bad – simply not of the required shape. Although these rejected vegetables have been described as ‘wonky’, in fact many are not wonky at all, but simply a little too large or too small, or too short or too long. Most of these vegetables are simply wasted – ploughed back into the ground, or at best used for animal feed.
And it’s not just shape; it’s colour too. Many producers of apples find a large proportion being rejected because they are too red or not red enough.
But do consumers really want standardised fruit vegetables? Are the supermarkets correct? Are they responding to demand? Or are they attempting to manipulate demand?
Supermarkets claim that they are just responding to what consumers want. Their critics say that they are setting ludicrously rigid cosmetic standards which are of little concern to consumers. As Hugh Fearnley-Whittingstall states:
‘It’s only when you see the process of selection on the farm, how it has been honed and intensified, it just looks mad. There are many factory line systems where you have people looking for faults on the production line; in this system you’re looking for the good ones.
What we’re asking supermarkets to do is to relax their cosmetic standards for the vegetables that all get bagged up and sold together. It’s about slipping a few more of the not-so-perfect ones into the bag.’
In return, consumers must be prepared to let the supermarkets know that they are against these cosmetic standards and are perfectly happy to buy slightly more irregular fruit and vegetables. Indeed, this is beginning to happen through social media. 
The pressure group 38 degrees has already taken up the cause.
But perhaps consumers ‘voting with their feet’ is what will change supermarkets’ behaviour. With the rise of small independent greengrocers, many from Eastern Europe, there is now intense competition in the fruit and vegetables market in many towns and cities. Perhaps supermarkets will be forced to sell slightly less cosmetically ‘perfect’ produce at a lower price to meet this competition.

The town of Kilkenny in Ireland has just hosted the sixth annual Kilkenomics festival (Nov 5–8) where economics and comedy meet. The festival brought together comedians and economists to take a look at some of the most pressing economic and social issues, such as the refugee crisis, economic recovery, banking and finance, the growth in inequality, the future of the EU, economic power, the environment and personal behaviour.
With stand-up comedians taking a sideways look at economic issues and top economists having their ideas lampooned, or lampooning them themselves, the festival provided a fun, but useful, reality check for the discipline of economics.
The festival attracted some major names in the field of comedy, economics, journalism and politics. Perhaps the biggest draw was the former finance minister of Greece, Yanis Varoufakis (see also), who opened the festival with a withering attack on the economic model being pursued by Greece’s creditors (the European Commission, the IMF and the ECB).
Much of the comedy was really aimed, not so much at economics and economists, but more at how politicians pursue economic policies and interpret economic models in ways that suit their own political agenda. But still there was no escape for economists. Much of the humour was directed at unrealistic assumptions and unrealistic visions of how economies function.

According to a an article in The Guardian, The best news in the world, by the president of the World Bank, Jim Yong Kim, there has been a dramatic fall in global poverty over the past two decades. The number of people in extreme poverty is projected to fall this year to below 10% of global population for the first time. This has been made possible, he claims, by unprecedented economic growth, especially in China.
But this raises three questions.
The first is whether, in the face of falling growth rates, progress in poverty reduction can be maintained.
The second is whether the World Bank is measuring extreme poverty in the right way. It is now defined as living on less than US$1.90 a day in 2011 prices – until a few weeks ago is was $1.25 in 2005 prices. As a result of this rebasing, global poverty falls from 14.5% of the world’s population (or 1011 million people) under the old method to 14.2% (or 987 million) under the new.
The third question is whether countries can improve their data collection so that a truer estimate of poverty can be made.
As far as the first question is concerned, Kim states that to stimulate growth, ‘every dollar of public spending should be scrutinised for impact. Every effort must be made to improve productivity.’ What is more, three things must happen:
|
|
| • |
Economic growth must lift all people. It must be inclusive. |
| • |
Investment in human beings is crucial – especially investing in their health and education. Malnourished and poorly educated children will never reach their full potential and countries, in turn, will fall short of their economic and social aspirations. |
| • |
We must ensure that we can provide safety nets that prevent people from falling back into poverty because of poor health, economic shocks, or natural disasters. |
As far as the second question is concerned, there are many who argue that $1.90 per day is far too low a measure of the extreme poverty threshold. It is a purchasing-power parity measure and is equivalent to what $1.90 would buy in the USA in 2011. 
But, according to the Jason Hickel article linked below, ‘the US Department of Agriculture calculates that in 2011 the very minimum necessary to buy sufficient food was $5.04 per day. And that’s not taking account of other requirements for survival, such as shelter and clothing.’ Peter Edward of Newcastle University, claims Hickell, ‘calculates that in order to achieve normal human life expectancy of just over 70 years, people need roughly 2.7 to 3.9 times the existing poverty line.’
But even if living on below $1.90 a day is defined as extreme poverty, it is important not to see the problem of poverty as having been solved for people who manage to achieve an income slightly above that level.
The third question is how to improve data. There is a paucity and unreliability of data in many developing countries. According to Kim:
Our report adds that data is sparse and inconsistent across the region and globally. Some 29 countries around the world had no poverty data from 2002 to 2011, so they could not track their progress. Another 28 had just one survey that collected poverty data during that time.
This is a situation that must change to improve the world’s ability to tackle poverty. In fact, we can’t accomplish our goal if we do not have enough information to know whether people are actually lifting themselves out of poverty. For that we need to address huge data gaps. We need robust data.

Questions
- Explain how the World Bank calculates the extreme poverty line.
- Why, if the line has risen from $1.25 per day to $1.90 per day, has the number of people recorded as being in extreme poverty fallen as a result?
- Why has the number of people in extreme poverty been rising over the years and yet the percentage of people in extreme poverty been falling?
- What policies can be adopted to tackle poverty? Discuss their practicality?
- Are reduced poverty and increased economic growth consistent policy goals? (See the blog post Inequality and economic growth.)
