Economic growth and Boris Johnson inequality debacle

After returning from an unpaid internship in Austria for the last three months, I was very interested to see Boris Johnson’s latest comments on inequality. After reading a number of articles focusing specifically on his comments relating to IQ, I  believe many had not picked up upon another important part of his argument – the implied justification that the current level of income inequality is acceptable because it a key and necessary driver of economic growth.

The argument that inequality drives economic growth goes back to the roots of economic theory itself. The theory argues that inequality generates incentives for individuals to work hard, compete and innovate within a market economy. A level of inequality allows for there to be winners and losers from this process and drives economic progress as individuals strive to reach the top. The theory therefore predicts that more unequal countries should grow at a faster rate. However, despite the strengths of this argument there are a number of reasons why an unequal distribution of income and assets within an economy may do precisely the opposite.

Many economists argue that highly unequal income distributions can lead to a number of economic efficiencies. Firstly, when the vast majority of wealth is concentrated in the hands of the few, it means that a smaller fraction of the population qualifies for credit because they lack the necessary collateral to obtain loans. As a result they may not be able to invest in the education of their children or gain sufficient funds to start a business. Productive investments within an economy, which stimulate growth, are therefore foregone.

Secondly, a higher level of inequality may lower the overall level of consumption within an economy. This is because people with lower incomes tend to spend a higher proportion of their income than those at the top. Consequently, if most of the national income is concentrated at the top, it is argued that overall consumption may fall. Moreover, the wealthy tend to spend a higher proportion of their incomes on luxury import and foreign travel whilst they may also seek tax havens for their saving abroad. This affects the economy through a process known as capital flight, such investments do not contribute to a country’s productive resources and can therefore hinder the prospects for economic growth.

Other authors have looked at the political economy implications of high levels of inequality for economic growth. For instance, when wealth is concentrated in the hands of the few, these individuals may take measures to safeguard their assets or capture more wealth instead of increasing their own productivity. Individuals may partake in disruptive rent seeking activities such as excessive lobbyingprovide large political donations or engage in bribery. In turn, all of this leads to inefficient use of resources as they are diverted away from productive activites which could stimulate economic growth.

A more recent argument is that high levels of income inequality may precipitate credit bubbles and financial crises. Here the argument is that when incomes grow at the top and those at the bottom stagnate, the demand for cheap credit increases. At the same time there is a push by those at the top for policies that sustain and build upon their wealth, such as lobbying for looser financial regulations. As explained by an influential study by the IMF, the end result is a viscious cycle of inequality whereby more and more individuals at the bottom have to borrow to keep afloat thus increasing the risk of a financial crisis.

This point I find particularly relevant as I believe it builds upon the Marxist theory that rising inequality would lead to the ultimate collapse of an economy. The basic argument here is that as business owners become richer by applying downward pressure on wages, the economy will come to a point where no one can afford to buy what the business owners are selling. At this point the economy will stagnate and reach the point of collapse. From this viewpoint, credit is just merely just a mechanism that allows individuals to spend above their means thus postponing the inevitable credit crisis.

But what about the empirical evidence.  Take the much cited case study of the Philippines and South Korea for example. In the early 1960s, both of the countries were similar on a number of macroeconomic indicators. They had comparable levels of GDP per capita, urbanisation, population size and primary and secondary education. However, over the period 1960-1988, the per capita income in the Philippines grew, on average, by only 1.8% a year. In contrast, per capita income in South Korea grew, on average, by 6.2% a year over the same time period. However, what is most interesting about this story is that, compared to South Korea, the Philippines exhibited a significantly more unequal distribution of income over the period measured. In 1965 the Philippines’ gini coefficient was nearly 17 points higher than that of South Korea. This clearly contradicts the argument that more unequal economies grow at a faster rate.

A number of more rigorous empirical studies have also found that high levels of income inequality have a negative impact upon growth. For instance, a frequently cited study by Alesina and Rodrik (1994) finds that the gini coefficient has a consistently negative effect upon economic growth. Likewise, Deininger and Squire (1997) investigate whether initial income inequality has a strong impact upon long term growth rates. They find that link between income inequality and economic growth is not strong however they do find that inequality in the distribution of assets (in this case land) exerts a strong negative effect upon growth.

On the whole the empirical evidence on the relationship between income inequality and economic growth is inconclusive at best. The studies conducted suffer from numerous data issues. For instance, inequality is measured in many different ways across countries making comparisons difficult. Conclusions made from many of the studies available are therefore tentative at best. As a result there is no clear evidence that income inequality has any impact on growth whatsoever.

The debate has still not been won by either side. While many accept (and I do too) that a level of inequality is necessary to drive economic development, it is not justification for the significant increases in income inequality we have seen over the past few decades. Furthermore, high levels of income inequality can have far more widespread ramifications for a country besides economic growth. As this interesting lecture by Richard Wilkinson shows, high levels of income inequality can have negative impacts upon a number of socio-economic factors such as health, life expectancy and levels of trust within society. Furthermore, a number of a studies have found a negative relationship between inequality and levels of overall happiness.

Nonetheless these are issues which will not be regularly mentioned within the political sphere. There is still a strong focus on crude indicators such as economic growth to gauge the success of our economy. Unfortunately politicians such as Boris Johnson are still very focused on this narrow gauge of development and therefore fail to see the negative socio-economic impacts that the forces of greed, envy and ultimately, inequality, can lead to.

Thatcherism – Some hard truths

In recent news I have been particularly concerned by the vast outpouring of sentiment for Margaret Thatcher over the past day or so. The same rhetoric has been repeated over and over again such as, “She changed the world” and, “the greatest prime minister in modern peace time“. However the most astonishing comment has to be from a fellow named David Cameron who proclaimed, “She saved our country“.

Now I am against the need to follow the standard cultural etiquette of not speaking against someone just because they have passed away. Individuals, particularly influential individuals should be judged on their contribution whether dead or alive. The ability to do this however has non-surprisingly been attacked by many Tory affiliates, for instance former Tory MP Louise Mensch has tweeted, “Pygmies of the left so predictably embarrassing yourselves, know this: not a one of your leaders will ever be globally mourned like her”.

So lets look at the facts, in 1979 when she came to power the country was experiencing double digit inflation, many major industries were in decline and trade unions had brought the country to a standstill in instances such as the winter of discontent. However by a combination of sweeping changes such as privatization, deregulation, industrial relations reform, taxation and deflationary measures the country began to find its feet again. After an initial recession the end result was what has be termed an economic miracle. The graph below shows the change in both inflation and GDP since Thatcher was elected.


This is what David Cameron was referring to when he proclaimed Thatcher saved the nation, GDP growth averaged 3.09% in the 1980s compared to 2.07% in the 1970s. Meanwhile inflation was reduced significantly to single digit values. However all too often politicians, the media and economists focus on such indicators as a sign of development and prosperity. There is a large debate within economics whether GDP is indicator we should be targeting when considering development and well-being. For instance, economist Richard Easterlin discovered empirically that found differences in income across countries and time did not signify a change in levels of happiness and well being. However he found within countries levels of income did positively correspond with levels of happiness.  The findings which became known as the “Easterlin Paradox” led Easterlin to theorize that changes in income do not affect happiness and well-being, relative income is what really matters. In this sense individuals derive happiness from being more well off than their peers, human beings are therefore constantly trying to “Keep up with the Jones”.

In this sense it could be argued that income inequality would be a better indicator to judge Thatcher’s economic performance. During her time in power the UK’s gini coefficient, a measure of income inequality with 0 representing a situation of perfect equality and 100 a situation of perfect inequality, increased from 27.39 in 1979 to 30.54 in 1980. Now this may not seem a great amount but in comparison from 1963 to 1979 (the furthest back the data goes) income inequality had only increased from 26.3 to 27.39 despite surges in inflation.


Other measures of income inequality by the IFS estimate the rise in income inequality to be even higher (gini coefficients and inequality measurements are usually dependent on the method used and can vary considerably).


In the above graph we can see that the level of inequality increased by nearly 8 points from 25.3 in 1979 to 33.9 in 1990. In addition to this the level of poverty also increased substantially during Thatchers reign.


The graph above shows that the percentage of people living below 60% of the median income increased from 13.4% in 1979 to 22.2% by the end of her reign in 1990. The webpage from which these graphs came paints an even grimmer picture such as a rising gender pay gap and record unemployment.

Thatcher’s policies such as the deregulation of the financial markets; the weakening of the trade unions; income tax cuts and the adjustment of industrial policy have all been highlighted by a number of authors as contributing to a wider gap between rich and poor. Although her policies promoted economic growth, this growth was not inclusive and the majority of the benefits accrued to the top end of the income scale. Furthermore it could be argued that the her legacy of promoting the deregulation of financial markets started a inevitable slide towards the 2008 financial crisis.

The death of Margaret Thatcher therefore leaves us to look at how we judge economic performance and development. If economic growth is all that matters then Thatcher’s reign could be considered a relative success. However if we are more concerned with the wider benefits of such growth issues of income inequality should become more prioritized.  Unfortunately this seems to have bypassed our current leader who unquestioned claimed that Margaret Thatcher saved the country. The reality is however, that in the long term, Thatcher’s policies led to a sustained increase in income inequality, decreases in social cohesion and arguably an inevitable road to economic collapse.

Japanese Gender Inequality and the Demographic Time Bomb – The Costs of Hard Work

Japan consistently ranks as one of the most developed countries in the world, however it may be a surprise to many that large and persistent gender inequalities still exist. Although Japan has seen increased levels of female education participation this has not translated into gender equality in the labour market. The country consistently ranks low on a number of gender equality measures. Most recently the country fell 3 places to 101st out of 135 counties in a recent survey by the World Economic Forum. The OECD reports that the gender pay gap remains high at 15% and this rises to 40% for older workers – this is the second highest rate among OECD countries. Female labour force participation sits at around 63% in comparison to 83% for men, if the current trend continues it could lead to a reduction in the size of the labour force by 10% over the next 20 years. Furthermore senior Japanese business women are a rare occurrence, the OECD shows that Japanese women only account for 3.9% of listed company board members this again ranks second lowest among OECD countries.

Such inequalities are compounding because gender equality is considered beneficial to many areas of economic development. Increasing female employment in general increases the size of the labour force and thus GDP. In addition gender inequality may lead to labour market distortions whereby men are employed in positions where women could be more productive. Recent estimates by Kathy Matsui of Goldman Sachs, finds that closing the gender employment gap could expand the Japanese workforce by 8.2 million. This she asserts could lead to a increase in Japan’s GDP of around 15%. Coupled with this some studies have found that in general women tend to save more than men. For instance Sequino and Sagrario Floro (2003) find that a one percentage point increase women’s share of the total wage bill tends to increase aggregate savings by approximately one quarter of a percentage point. This means for countries such as Japan that increased female labour force participation could lead to higher rates of saving and hence increased investment.

So what are the problems Japan faces? One of the most potent statistics is that 70% of women in Japan leave the workforce as soon as they have their first child. The ratio of Japanese mothers with children under six who work (34%) remains extremely low compared to 76% in Sweden, 61% in the US, 55% in the UK, and 53% in Germany. Matsui’s report suggests that once Japanese women leave the workforce they generally find themselves returning to limited part time employment due to increased responsibilities  She explains the “typical” lifestyle for a Japanese women is as follows;

  1.  Graduate from high school or university and find a job (average age: 18-22 years)
  2.  Get married (age: 25-29 years)
  3.  Become pregnant, then drop out of workforce in order to raise the child(ren) (age: 30-39 years) 
  4. Once the child(ren) become(s) independent, resume work (approximate age: 45+ years) 
  5. Even if work is resumed after age 45, it is typically limited to part-time employment, since by this stage either her husband’s or her own parents often begin requiring convalescent support.

A particular issue is that of lack of available and affordable daycare. For instance Tokyo government statistics show that there are more than 20,000 children waiting for daycare places in the city. In addition to this the work culture in Japan means that men tend to devote less time aiding in childcare. The graph below from Matsui’s report shows the average number of hours spend by men on household activities and childcare.


The graph shows that on average Japanese men spend less than an hour on these combined activities. To further compound this problem only 2.63% of men take paternity leave due to the fear of losing their jobs. Such statistics show the increased pressures placed upon Japanese mothers to leave the labour market.

In addition, these issues have led to two principle problems, firstly women who are having children are not working. Secondly those that are working are  not having children. Consequently Japan now has one of the lowest birth rates in the world with 1.3 births per women and now faces the prospect of seeing its population decline by a third over the next century if trends continue.

The irony of such problems is that Japan’s famed work culture and ethic which once drove the country’s rapid development  is now partly responsible. The pressures of long hours and vigorous commitment mean that the country is now facing a demographic time bomb whilst many of its potential female workers remain under utilized. However government policy to provide more daycare centres and child bearing incentives is only one half of the solution. As a recent survey by the The Yomiuri Shimbun shows the share of Japanese who thought wives should stay at home jumped 10.3 percentage points to 51.6 percent between 2009 and 2012. The dilemma therefore is therefore not only policy problem but also a cultural issue as well.

Visualizing Income Inequality in the UK


I thought I would share this image as it was the first to really draw my attention to income inequality and the massive wealth disparities in the UK. The image above taken from an article by The Atlantic represents a famous picture of income inequality construed by the Dutch economist Jan Pen. Using data from the UK in 1971, he asked us to visualize a parade of people which would take one hour to pass, however this parade would have two intriguing features. Firstly the people involved would be arranged by their levels of income – the poorest at the front leading to the richest at the back. Secondly the heights of the people in this parade would be directly proportional to what they earn. Pen asserted that the following parade would look rather peculiar. Instead of a steady progression of people with increasing heights during parade, we would observe mostly a continuous line of dwarfs and then unimaginably tall giants at the very end.

The unfortunate part about this story is that since Pen came up with this image the number of dwarfs has increased, whilst the giants have become even larger. Since the data he compiled in 1971, the UK’s level of income inequality has risen considerably. The UK’s gini coefficient, which takes a value between 0 (perfect equality) and 1 (perfect inequality), sat at 0.26 in 1979 whilst the last estimate in 2005 put the score at 0.34 (Data from UNWIDER). When the next inequality figures come out the gini coefficient is surely set to rise whilst the some early reports have suggested that income inequality is now at its highest since the 1930s. Substantial cuts to welfare, rising inflation and tax breaks for the top earners will all further add to this problem and ultimately lead to negative effects both socially and economically.

China – a country example of the Kuznets Curve in the making?

So its Valentines day. With my girlfriend away and another 9 hour shift at work finished I’ve decided to talk about inequality! After reading this article (http://theconversation.edu.au/china-tackles-income-inequality-but-is-silent-on-state-corruption-12065) the other day it struck me that China may be fulfilling the predicted Kuznets Curve.

Observed by Simon Kuznets in 1955, the Kuznets Curve predicts that inequality within a country will follow a determined path as it develops. At low levels of income, countries may exhibit traditional industries such as subsistence farming which generates low levels of inequality. However as a country urbanizes and industrializes, income accrues to the owners of physical and human capital (e.g. factory owners and university graduates) causing inequality to rise. As more and more individuals are drawn into cities from the rural countryside, there may be calls for democratization and welfare policies. Furthermore there may be the emergence of trade unions as factories and cities allow workers to easily conglomerate and effectively organize themselves. The result is that inequality decreases leading to an inverted U-Curve as shown below.


Originally observed as a cross sectional relationship over many countries, the Kuznets curve has been disputed by many as they argue that the relationship depends on the inclusion of Latin American countries – which typically exhibit high levels of inequality. In addition some developed countries such as the UK and United States have been exhibiting rising levels of inequality in the past decade. The curve is important because it represents the search for an implacable law of development.

It seems China may be about to follow this path. For instance in the late 1970s China’s Gini coefficient, an indicator of income inequality that lies between 0 (perfect equality) and 1 (perfect inequality), hovered around 0.27. Back then the economy was largely agriculturally based and socialist. However after years of rapid growth and industrialization the country now exhibits a gini coefficient of 0.474 whilst some unofficial estimates have been as high as 0.61.

Interestingly though the article asserts that the Chinese government has now introduced a number of reforms to combat inequality. Notably it points out that the reforms are in response to the need to maintain social stability amid concerns of rising inequality. So here we maybe seeing the Kuznets Curve in action and it will interesting to see if inequality in China does truly decrease over the next few years, more importantly I believe this may be the start of a long process of democratization in China. On the other hand it does show that the hypothesis is ultimately dependent on a number of conditions such as government action.
