This post contains an essay submitted as part of student course work for the Planning 100 "Introduction to Planning" course taught by me this year at Planning School, University of Auckland. The topic for the essay is: Use appropriate references to explain what is meant by economic
growth and how and why economic growth has changed in the past
two centuries. Explain the use of “GDP” as a measure of economic
activity and discuss its usefulness. The essay explores the topic and also considers economic development in China. It is by Yin (Nikki) Hui, who has kindly given permission for it to be published here.
Economic growth is defined as an increase in the number of goods and
services produced in an economy in a given time period, usually a year
(Sabillion, 2007). For the majority of human history, economic growth has
been so slow as to be non-existent. However, from approximately 1750, there
was a “Great Divergence” which resulted in an exponential amount of growth
in Great Britain, allowing the citizens of Western Europe to obtain previously
unprecedented levels of wealth. Economists have largely debated over the
causes of this growth and why Great Britain was the first to industrialize. (“The
road to riches”, 1999). The first part of this essay will argue why the key
reasons behind this growth was due to changes in political and economic
institutions (Acemoglu & Robinson, 2012). The second part of this essay will
discuss the usefulness of using GDP (Gross Domestic Product), as a
measure of economic growth and the limitations of this measure, as well as
ways in which it can be strengthened.
During the 19th and 20th century, economic growth resulted in a tenfold
increase in average world income (Maddison, 2003). Some economists argue
that an advance in science and technology was the reason behind this
growth. Technology and knowledge tend to concur, as technology is driven by
scientific knowledge. The discovery of atmospheric pressure gave rise to
James Watt’s steam engine in 1744, which was the driving force behind the
British industrial revolution (“The Road to Riches”,1999). However, technology
does not necessarily lead to economic growth when we look to China as an
example. At the start of the 15th century, China’s supremacy in science and
technology was astounding, and it was on the verge of industrializing. The
Chinese had already invented the compass, gunpowder and the wheelbarrow
well before these ideas had had even reached the West. However, in 1400
technological process halted and by 1600, China had fallen behind Europe. If
technology were the driving force behind economic growth, China would have
been the first country to industrialize; yet this was not the case (Ringmar,
2007).
What fundamentally lead to Britain’s modernization was not technology, but
the particular institutions that were present within British society. Institutions
are defined as “formal rules, informal norms and their enforcement
characteristics” (Ringmar, 2007). No two societies will have the same
institutions as societies are subject to economic and political conflict that is
resolved in different ways. These differences are often unnoticeable at first,
but they accumulate, creating a process of institutional drift. European growth
has accelerated phenomenally in the past two centuries because of two
critical junctures in history. At the turn of the 14th century, Europe had a feudal
order. The king owned all land and granted control of the land to the lords.
Peasants or “serfs” had to perform unpaid labor on the land and were subject
to taxes and fines. Then in 1348, the Black Death shook up the foundations of
the feudal order. The plague resulted in a shortage of labor, and workers
demanded more freedoms and higher wages. The Peasants’ Revolt broke out
in 1381, and as a result, feudal services diminished and an inclusive labor
markets began to rise. The second critical juncture occurred in 1600, with the
expansion of world trade in the Atlantic Ocean. In Britain, Elizabeth 1 and her
successors were unable to monopolize trade with the Americas. This created
a group of wealthy traders who opposed absolutism and demanded changes
to the institutional structures of Britain (Acemoglu & Robinson, 2012).
While economic institutions are important in determining the prosperity of a
nation, it is political institutions that determine what economic institutions a
nation has. The previous critical junctures gave power to the citizens who
formed a coalition which was able restrict the power of the monarchy and
executive, forcing them to listen to the demands of the coalition. The shift in
power from the elites to the general masses sparked the Glorious Revolution
of 1688. The Glorious Revolution diminished the power of the monarchy and
enabled Parliament to determine the economic institutions which would foster
investment, trade and innovation. These included patents, which granted
property rights for ideas, the application of English law to all citizens, the
ceasing of arbitrary taxation and the abolition of monopolies. Furthermore, the
state promoted merchant activities and rationalized property rights to facilitate
the construction of the infrastructure that would be key to economic growth.
Property rights in particular are important, as they create an incentive for
entrepreneurs to invest in order to increase productivity. These institutional
changes underpinned the Industrial Revolution of 1750-1850 (Acemoglu &
Robinson, 2012).
As a result of inclusive economic institutions, inventors such as James Watt,
who perfected the steam engine in 1774, were able to become innovative
because they were confident their property rights would be respected and
they had access to markets where their innovations could be profitably sold.
When institutionalized, technology can lead to increased productivity and
growth (Sabillion, 2007). This growth greatly benefited the working class,
whose living standards rose sharply from 1820 and onwards. Industrialization
then spread to the United States, which became first nation to adopt the new
technologies coming from Britain. The War of Independence and enactment
of the U.S Constitution Act displays similar characteristics to the long struggle
in England of parliament against the monarchy. The French Revolution was
another critical juncture that meant the institutions of Western Europe started
to converge with those of Britain, and conversely, these nations were able to
industrialize (Ringmar, 2007).
Looking to the other side of the world, China had experienced great things in
the past but had grown conservative over the years. China was a feudal
society that was ruled by a despotic emperor and bureaucratic elite. In the
15th century, these rulers stopped long-sea voyagers, blocking trade and
commerce, which meant growth stagnated (Sabillion, 2007). However, China
is also one of the examples of how changes to the institutional structures of a
country can send it on a different path of economic growth. During 19th and
20th century the economy was in a process of decline under the rule of the
Communist Party and Mao Zedong. Consequently, the political and economic
institutions created were highly extractive in nature. In the 1950s, Mao
promoted the Great Leap Forward and in the 1960s he propagated the
Cultural Revolution. These initiatives led to the mass persecution of
intellectuals and educated people and the death of millions. However, when
Mao died in 1976, Deng Xiaoping came into power and implemented several
economic reforms. Economic incentives were given to farmers, foreign
investment was encouraged, and state owned enterprises underwent
privatization. Despite the economy stagnating changes to economic
institutions meant there were reductions in poverty and income inequality from
the 1970s onwards and China experienced a phenomenal growth rate of 9.5%
a year (Acemoglu & Robinson, 2012).
Since historical times, growth has been commonly measured using GDP,
which is the annual market value of final goods and services produced in a
nation after accounting for changes in inflation. GDP is a measure of market
activity, yet it is commonly used as an indicator of quality of life. However,
GDP has many limitations which make is less useful as a measure of
economic performance. The global economic crisis took many by surprise
because of the high performance of the world economy between 2004 and
2007. During this period, temporary profits in the financial industry, increasing
debt levels, and the real estate bubble painted a false picture of true
economic conditions. This highlighted the fact our current system of
measurement is failing us, and steps should be taken to improve GDP as a
measure of economic performance and social progress (Stiglitz et al, 2010).
One of the limitations of GDP is that it does not give any indication of income
distribution. Although GDP may be increasing, this wealth may be only going
to a select few in the economy, which decreases equity. Moreover, GDP
includes expenditures that do not increase standards of living. For example,
traffic congestion may increase GDP as a result of the increased fuel
consumption, but this depletes air quality and time is wasted while travelling.
Costs related to natural disasters and the cleaning up of pollution are also
accounted for as positives in GDP (Anew NZ, 2006).
Furthermore, non-market activity is not accounted for in GDP. Many services
people have received from family members in the past for free are now
purchased on the market. This may translate to a rise in income and
standards of living, although this is not the case. Non-monetary services
contribute an important role to economic activity, yet they are not reflected
when calculating GDP (Anew NZ, 2006).
More importantly, one of the most fundamental limitations of GDP is that it
fails to take into account the effect economic expansion has on the
environment, which has issues concerning sustainability. We live within a
finite biosphere, and when growth encroaches too much on surrounding
ecosystems, we will begin to sacrifice natural capital such as fish, minerals,
and fossil fuels, which have more economic value than man-made goods. If
we continue to deplete these resources they will no longer be available for
future generations to benefit from. We are facing a looming environment
crisis, especially over concerns of global warming, yet carbon emissions are
not reflected in GDP. Clearly, if the environmental costs of production and
consumption were reflected, measures of economic performance would look
vastly different (“Economics in a Full World”, 2005).
Despite it’s limitations, GDP is hard to replace because it provides one
summarized figure, which is comparable between nations. In a single number
you get an idea of whether the economy is expanding or contracting, and this
can be comparable over time. However, since GDP is used as a measure of
people’s well being there needs to be more incorporation of quality of life
factors that go beyond measuring output. These factors include health,
education, political voice, social interaction and the environment (Stiglitz et al,
2010). The General Progress Indicator (GPI) is an example of an alternative
measurement to GDP. It measures well being by taking into account of
economic, social and environmental factors. In the GPI, the costs of pollution,
the loss of natural resources, and ozone depletion are all submitted as
negative (Anew NZ, 2006).
Furthermore, in order to make GDP a more useful measure of economic
health and well being, focus should be taken away from production into
income and consumption, as material living standards are more closely
associated with these measures. In addition to this, the indicator should also
reflect distribution of income. Particularly, measuring government provided
services, such as education, should be improved as these contribute a vital
role to economic activity and benefit society greatly. Lastly, GDP could be
improved through broadening income measures to non-market activities, by
showing how people spend their time over years and across countries to give
a better reflection of change (Stiglitz et al, 2010).
In conclusion, economic growth is usually characterized by a rise in the living
standards of people. The economic growth that occurred during the 18th and
19th century that started in Britain, and then spread to other parts of the world
was a result of changes to political and economic institutions. These changes
influenced the way society was governed, and thus how individuals behaved.
These actions either allowed for economic growth, or stunted it. GDP is the
most commonly used method to measure growth. However, GDP has many
limitations, which restricts its usefulness. If GDP is used as a measure of wellbeing,
it needs to be improved or alternative measures need to be sought, as
human well being incorporates various factors that are separate from material
wealth. The human population is now better paid, educated and fed than his
forefathers could have ever imagined. Yet this growth has been largely
unsustainable, which raises the question of whether we can continue to see
improvements in human standards of living in the future.
