Economic Growth - Constraints

Introduction

Economic growth is not guaranteed and some countries struggle and sustain the minimum growth rate needed to bring down poverty and sustain their chosen development path.

What Factors Can Limit Growth and Development?

In this section we will explore some of the many growth limiters that a country may face
1 / Infrastructure
  • Infrastructure includes physical capital such as transport networks, energy, power and water supplies and telecommunications networks.
  • Evidence shows that there is a strong positive correlation between a country's economic development and the quality of its road network
  • Poor infrastructure hampers growth because it causes higher supply costs and delays for businesses. It reduces the mobility of labour and affects the ability of exporters to get their products to international markets.
Here are three examples of infrastructure deficiencies:
India: India’s irrigation system is deficient and not properly managed and this has made it very difficult to sustain food grain production when rainfall is less than expected – as was the case in 2012. This has led to a surge in food prices which hits the poorest communities hardest. For a few days in the summer of 2012, much of northern India was plunged into darkness for two consecutive days. About 700 million people were left without power, a situation that affected transport, communication, healthcare, industries and farming. India needs an estimated $400bn investment in the power sector if it is to meet its development goals.
Brazil: Host for the 2014 World Cup and the 2016 Olympics. Brazil’s growth is constrained by infrastructure weaknesses: In 2011, only 14% of her roads were paved. The World Economic Forum ranks Brazil’s quality of infrastructure 104th out of 142 countries surveyed, behind China (69th), India (86th) and Russia (100th). 
Sub-Saharan Africa: The combined power generation capacity of the 48 countries of Sub-Saharan Africa is 68 gig watts – no more than Spain’s. Excluding South Africa, this figure falls to 28 GW, equivalent to the capacity of Argentina (except Argentina has a population of 40 million and Africa has 770 million.) A recent report from the Infrastructure Consortium of Africa (ICA), found that poor road, rail and harbour infrastructure adds 30-40% to the costs of goods traded among African countries. This chronic shortage of energy - with firms and people facing acute shortages of power – is a major barrier to growth and development.
One key barrier to infrastructure investment in developing countries is that tax revenues are low or come from a narrow base of businesses. For example, East African Breweries accounts for nearly 10% of the direct and indirect tax revenues going to the Kenyan government.
Many countries will need to increase their spending on infrastructure in the years ahead to adapt to and deal with the consequences of climate change. There has been much interest in recent years concerning the investment in infrastructure that businesses from emerging countries such as Brazil and China are making in the continent of Africa. China’s foreign direct investment in Africa has jumped from under $100 million in 2003 to more than $12 billion in 2011.
2 / Dependence on limited exports
  • Many nations still relying on specializing in and exporting low value added primary commodities. The prices of these goods can be volatile on world markets.
  • When prices fall, an economy will see a sharp reduction in export incomes, an adverse movement in their terms of trade, risks of a higher trade deficit and a danger that a nation will not be able to finance state-led investment in education, healthcare and core infrastructure.

Here are some examples of export dependence for a selection of countries in Sub-Saharan Africa: The data shows the % of total exports in 2010:
  • Angola: 97% oil
  • Ghana: 39% gold, 26% oil, 17% cocoa
  • Kenya: 19% tea, 12% horticulture
  • Nigeria: 90% oil
  • Senegal: 11% fish, 11% phosphate
  • Tanzania: 37% gold
  • Uganda: 18% coffee
  • Zambia: 84% copper
Sub-Saharan Africa (SSA) is often cited as a region where primary sector dependence is high. SSA’s share in global manufacturing trade remains extremely low.
3/ Vulnerability to external shocks
Events in one part of the world can quickly affect many other countries. For example, the global financial crisis of 2007-2010 brought about recession in many countries and deep financial distress in many regions. It also led to a fall in foreign direct investment flows into many poorer countries and pressure on governments in rich nations to cut overseas aid budgets.
If a resource rich country exports the resource, then it exposes itself to damaging volatility of its export earnings. In 2010, economists Bruckner and Ciccone found that a 10% fall in income due to falling commodity prices raises the likelihood of civil war in sub-Saharan Africa by around 12%.
4/ Landlocked countries
Land-locked economies face particular challenges to integrate in global trade – without good infrastructure and efficient logistics businesses it can be difficult, costly and slow to get products to the countries of trade partners - but some landlocked countries have been doing well especially when they achieve regional economic integration with other land-locked nations.
5/ Low national savings and low absolute savings
Savings are needed to provide finance for capital investment. In many smaller low-income countries, high levels of poverty make it almost impossible to generate sufficient savings to provide the funds needed to fund investment projects. This increases reliance on overseas borrowing or tied aid.  This problem is known as the savings gap. In Africa for example, savings rates of around 17 percent of GDP compare to 31 percent on average for middle income countries. Low savings rates and poorly developed or malfunctioning financial markets make it more expensive for African public and private sectors to get funds for investment. Higher borrowing costs impede capital investment.
Problems facing The Bottom Billion – Paul Collier’s 4 Development Traps
Professor Paul Collier finds that the living standards of the world's bottom billion have stagnated over the past forty to fifty years.
He identifies four “development traps” - they are conflict, reliance on natural resources, being landlocked with bad neighbours, and bad governance.

6/ Limited financial markets
Many of the least developed countries have limited financial markets such as banking, money and credit systems, insurance markets and stock markets.
Worldwide, approximately 2.5 billion people do not have a formal account at a financial institution. Access to affordable financial services is linked to overcoming poverty, reducing income disparities, and increasing economic growth
These are essential for providing long term capital for the private sector and helping to channel savings and provide funds for investment projects.
Some progress is being made in Sub-Saharan Africa – there are now 19 stock markets in operation – but most of these are very small by international standards.
The Nigerian stock market accounts for only 3% of Brazil’s or India’s stock market capitalization.
6/ Volatile incomes and employment
Income growth so much more volatile in poor countries than in rich ones:
Volatility can be disruptive to economic health. It increases the risks for businesses considering capital investment, it raises the chances of people falling into extreme poverty and it makes a nation’s finances more fragile perhaps lowering the scope for important investment in public goods.
7/ Weaknesses in business management
Few development textbooks give much emphasis to the complex roles for and effects of business management as a constraint on growth and subsequent development. A fundamental cause of poverty is low wages and poverty pay is linked to relatively low productivity (measured in different ways, one of which is the value of output per person employed).
Economists such as Nicholas Bloom from Stanford University have been studying the impact of weak management in some developing countries including India. Bloom has argued for example that “In India are badly managed: equipment is not looked after, materials are wasted, theft is common because inventory is not monitored, defects keep occurring, etc.  In a recent project with the World Bank, we found that giving management advice to Indian factories increased productivity by 20%.”
Weaker management may also help to explain why many poorer countries have not fully and intensively adopted new technologies. Economist Diego Comin finds that extensive adoption of new technologies has accelerated in recent years – witness the rapid expansion of mobile technology in many African countries – but that many of the least developed countries tend to use technologies less intensively - fewer people use less advanced computers less often.
8Capital flight
Capital flight is the uncertain and rapid movement of large sums of money out of a country. There could be several reasons - lack of confidence in a country's economy and/or its currency, political turmoil or fears that a government plans to take privately-owned assets under government control
Capital flight can lead to a loss of foreign currency reserves and put downward pressure on an exchange rate – driving the prices of essential imports of goods and services higher.
According to figures from Global Financial Integrity, developing countries lost $5.86 trillion in 2001-2010 to illicit financial flows
9/ Conflict, corruption and poor governance
Governance refers to how a country is run and whether the exercise of authority manages scarce resources well improving economic outcomes and the quality of life for a country’s people. High levels of corruption and bureaucratic delays can harm growth by inhibiting inward investment and making it likely that domestic businesses will invest overseas rather than at home.
Governments need a stable and effective legal framework to collect taxes to pay for public services. In India, there are 15 times more phone subscribers than taxpayers. If a legal system cannot protect private property rights then there will be less research and development & innovation.
Conflicts – there have been an estimated 150 conflicts since 1945 with 28 million deaths (this is twice the toll of WW1). Conflicts have huge collateral damage effects – for example, Angola has lost 80% of its farmland because of landmines. Most conflicts are intra-state i.e. civil war and reconstruction can take decades and many countries remain aid-dependent. About 1.5 billion people live in countries suffering repeated waves of political and criminal violence.
A recent example of the cost of conflict comes from the Ivory Coast. After a disputed presidential election in late 2010 violence erupted and the country descended into a four-month civil war that killed an estimated 3000 and displaced around a million people. The war could only be ended by a French intervention in April 2011. Since then the new government under President Ouattara has struggled to re-establish security but raids against army and policy installations still threaten stability.
Corruption has long been a barrier to sustained growth and development in Africa. Conflict has had terrible consequences; over one third of economies in Africa have suffered some kind of warfare from Rwanda, Sierra Leone, Eritrea, Uganda, and Somalia.
That said encouraging progress has been made in building democratic institutions in many African countries.
Economic growth can collapse and go into reverse when states fail – there are numerous reasons whychronic government failure can hamper growth and development:
  • Failures to protect property rights and provide sufficient incentives for new businesses to flourish
  • Forced labour, caste labour and other forms of discrimination –  all of which waste scarce human resources not least limiting the roles that women can play in labour markets and – over the long term - holding back innovation and technological progress (two key drivers of growth)
  • Power elites controlling an economy - using their power to create monopolies and blocking new technologies
  • Stateless areas - large parts of the world are still dominated by stateless societies where the rule of law barely exists
  • Public goods - chronic failures to provide basic and effective public services such as education, health and transport. Many of the world’s least developed countries have not built effective tax systems and so their revenue base is inadequate for much needed capital investment and the annual revenues required to provide public health and education programmes
  • Conflicts – there have been many conflicts over natural resources e.g. in Sierra Leone
10/ Population decline and / or an ageing population
  • In some countries the size of the population is declining as a result of net outward migration
  • If a nation loses younger workers, this can have a damaging effect on growth
  • The changing age-structure of a population also matters, leading to a fall in the ratio of workers to dependants
Demographic change is important to many of the fast growing countries in Asia.
  • Most countries in East Asia are expected to experience a decline the portion of their working age population (15-64 years) to total population from now until 2025
  • Seven countries are expected to see declines of 10 percent or more (including China, Japan, Thailand and Vietnam) while three will see declines of over 20 percent (Hong Kong SAR China, Korea and Singapore)
  • Countries such as Indonesia, Mongolia, Myanmar and Vietnam are forecast to see a decline in their population size due to a combination of emigration and demographics
Declining populations in Eastern Europe
Many countries in Eastern Europe must face the challenges of continued population decline. Only two out of twelve countries will experience population growth according to recent estimates.
The relationship between demographic trends, per-capita income and economic growth is complex. Lower per-capita income should lead to higher growth, but it also has a negative impact on labour supply. Eastern Europe will have to rely on capital accumulation and productivity growth rather than labour force growth to generate economic growth.
One of the BRIC countries – Russia – is experiencing a sustained decline in their population and their active labour force. High levels of net migration, rising death rates linked to exceptionally high accident rates and the effects of alcohol abuse have all contributed to a fall in population to below 150 million.
Globally the world’s population is ageing. Within next 10 years, there will be 1 billion older people worldwide. By 2050 nearly one in five people in developing countries will be over 60
11/ Rising inflation
Fast growing countries may experience an accelerating rate of inflation which can have damaging economic consequences.
Two effects in particular can hit growth, namely falling real incomes and profits together with higher costs and also reduced competitiveness in international markets.
12/ Persistent trade deficits due to rising imports
Some countries may experience large deficits on the current account of their balance of payments. This means that the value of imported goods and services is greater than the value of exports and net investment incomes leading to an outflow of money from their economy.
High trade deficits might have to be covered by foreign borrowing (increasing external debt) or a reliance on inflows of capital investment from overseas multinationals
Large trade gaps can eventually lead to a currency crisis and possible loss of investor confidence.
13/ Over-extraction of the natural resource base
Natural resources provide an important source of wealth for many lower-income countries and when world prices are high, there is an incentive to increase extraction rates to boost export earnings.
This might lead to an excessive rate of extraction that damages growth potential
Deforestation and rapid extraction of oceanic fish stocks are two good examples of this.
A report from the OECD published in 2012 found that there is a growing need to improve the sustainable use of available land, water, marine ecosystems, fish stocks, forests, and biodiversity. Some 25% of all agricultural land is highly degraded.
Critical water scarcity in agriculture is a fact for many countries
Extreme weather events are becoming more frequent and climatic patterns are changing in many parts of the world. The damaging effects of these extreme climatic events tend to fall most heavily on the poorest and most vulnerable communities in developed and developing countries.
14/ Inadequate investment in human capital
To sustain growth requires improvements in productivity, research & development and innovation. Whilst physical capital such as factories and technology plays a role, so too does the quality of the human input into production.
Economic growth might be limited by skills shortages as businesses seek to expand which forces up average wages and labour costs.
High level skills and qualifications are also needed to help businesses to move up the value chain and supply products that can be sold for higher prices in the world economy.
In many of the least developed countries there are acute shortages of human capital. Although primary enrolment rates have risen, secondary enrolment and teacher quality is poor and the tertiary education sector is tiny and low-quality. Some countries lose some of its limited skilled workforce to other countries. Gender inequality can have a hugely negative effect on human capital development.
15/ High levels of inequality of income and wealth
Although two decades or more of globalisation has strengthened average growth rates in many lower and middle-income countries, it has brought an increase in inequalities of income and wealth.
When the gap between rich and poorer communities gets bigger there are many possible dangers not least the costs of social tension and conflict and increasing spending on insurance, law and order systems and government welfare bills.
Recent theoretical work finds a negative correlation between income inequality and economic growth. One book that supports this view is The Spirit Level (Pickett and Wilkinson) which finds evidence that unequal societies may become less competitive over time.
16/ Gender inequality and discrimination
In many countries women are subject to deep-rooted cultural norms that prevent them playing a full and active role in their economy.
  • According to the World Bank, 232 million women live in economies where they can't get a job without their husband's permission
  • Less than 10% of credit for small farmers in Africa is directed to women
Some progress is being made, from 2009 through to 2011, 39 developing countries made legal changes towards gender parity – but only 38 out of 141 nations set the same legal rights for men and women in their own labour markets
Economic and social dangers from rising inequality
17/ Malnutrition and limits to growth and development
High rates of malnutrition can severely impair development and bring untold human misery. Poor nutrition can have serious negative effects on development prospects:
  • It impairs brain development among the young – nearly one in five children aged under five in the developing world is under-weight
  • It is responsible for half of all child deaths – 38% of under-five children in the poorest 20% of families in developing countries are underweight compared to 14% of under-fives in the wealthiest 20%
  • It increases the risks of HIV infection and cuts the numbers who survive outbreaks of malaria
  • Malnourished children are more likely to drop out of school and suffer reductions in their lifetime incomes
  • According to the World Bank, “the effects of this early damage on health, brain development, educability, and productivity caused by malnutrition are largely irreversible.”
  • The surge in global food prices has had a terrible effect on the risk of malnutrition in many of the world’s poorest countries. It has certainly led to a sharp rise in premature deaths and severe illnesses linked to poor nutrition in countries such as India.
Here is the 2011 data for the % of people who are undernourished:
  • Sub-Saharan Africa: 27% (equivalent to 231 million)
  • Southern Asia: 20%
  • Developing regions: 15%
  • Rural children in developing countries: 32%
  • Urban children in developing countries: 17%
There has been progress in reducing malnutrition but high prices for basic foods in recent years have curbed this trend.

Policies to reduce malnutrition
  • Schemes to promote health and nutrition education plus direct provision of micro-nutrient supplements and fortified foods
  • Growth monitoring schemes for the newly born and infants supplemented with vitamin provision from community organisations
  • Targeting cultural norms – in some countries, young girls are often allowed to eat only after their brothers
  • Cash transfers – i.e. consumer subsidies that can be spent on certain foods
  • Government subsidies for grain prices and export bans on domestically produced foods
  • Better food prices paid to small-scale farmers
  • Opening up retail markets to international supermarkets where food prices might come down through economies of scale and increased competition
Infrastructure spending to improve access to and improved quality of sanitation and clean water supplies


The Greek Economic Crisis

Case Study: The Greek Economic Crisis – Debt, Default, Deflation and Social Breakdown
Macroeconomic indicators for Greece – negative growth and mass unemployment
  1. Greece has been a member of the single European currency since it was launched in 2001
  2. 2013 will be the sixth year in succession that Greece has been in recession
  3. Cumulatively the economy will have lost more than 20% of national output before a recovery starts
  4. Private sector demand has collapsed, there have been deep falls in consumer spending on goods and services and even great reductions in real private sector capital spending
  5. Government consumption on state-provided goods and services is now shrinking rapidly too as the fiscal austerity measures take effect.
  6. This combination of weak private sector demand and a contracting public sector makes it inevitable that the Greek economy stays in recession
  7. Net trade (X-M) is making a small contribution to positive growth and the current account deficit is likely to dip below 5% of GDP for the first time in several years. But this on its own is insufficient to provide Greece with the means to achieve a sustainable recovery
  8. Greek national output is vastly below potential – there is a huge margin of spare capacity
  9. This is one reason why the Greek economy remain at risk of price deflation – which given the scale of national and private sector debt could be catastrophic. Low positive inflation is good news for Greece if it helps to restore price competitiveness, deflation would be a different story.
  10. Unemployment has reached historic highs, more than 25% of the working population is out of work and youth unemployment has soared to nearly 60%
  11. Despite austerity measures the fiscal deficit remains high and national debt will move higher – towards 190% of GDP. IMF aims to bring this down to 120% of GDP in 2020 look fanciful.
  12. The OECD estimates that the trend rate of growth for Greece is zero or perhaps slightly negative – this is highly unusual and reflects the depth of the economic and fiscal crisis facing the country. The IMF does not see Greece returning to growth until 2015 by which time its economy is forecast to be 25% smaller than at the start of the crisis.
The Greek Debt Crisis
The Greek economy became embroiled in a huge debt crisis in the aftermath of the global financial crisis from 2007 onwards. Having struggled to keep public sector spending under control and tackle widespread tax evasion, it became clear a few years ago that the annual Greek budget deficit was much higher than expected. About €30bn annually of tax revenues go uncollected in Greece.
The tipping point for Greece was the immediate and short-run fall-out from the Global Financial Crisis (GFC). Students ought to be familiar with the background here. The sub-prime mortgage crisis in the United States quickly turned into a major global financial meltdown affecting most countries but especially those with highly leveraged financial systems i.e. banking systems and other lenders that had created too much credit to private sector businesses and individuals.
The Greek economy was hit by a fierce demand-side shock and this was made worse because the economy was already suffering from structural competitiveness problems inside the single currency system.

As a direct consequence of the GFC:
  • Most of Greece’s main trading partners went into a deep recession – cutting exports
  • There was a 2% fall in world output (unusual) but worse, a 12% fall in global trade
Greece suffered badly because her economy was heavily dependent on tourism and construction, two sectors badly hit by the sharp fall in demand and production.
In 2009 Greek exports collapsed by nearly a fifth (causing a large inward shift of AD) and the Greek fiscal deficit grew from 5% of her national income in 2007 to nearly 14% in 2009. A decade of progress in reducing unemployment was reversed within the space of two harsh years.
The Greek government has run a budget deficit in every year of at least 4% of GDP. Even during the first half of the last decade there was a sizeable deficit although corruption and fraud meant that the official figures hid this. The deficit peaked at over 15% of GDP in 2009 and in 2011 the budget deficit was nearly 10%. Strong growth in Greece helped to keep the government debt to GDP ratio at or around 115% during the years from 2001 to 2008 but a combination of huge annual deficits and six years of recession has brought about a huge rise in the scale of the national debt.
The OECD is forecasting that this will reach 200% of GDP in 2014 despite attempts to cut the deficit. The reason is simple – even though the Greek budget deficit is coming down, their economy is shrinking so the base level of real GDP is falling. In December 2012, the 'troika' of the IMF, the EU and the European Central Bank reached a new funding agreement for which will cut Greece's long term debt burden. And Greece has made some progress in cutting the annual budget deficit. Greece reduced its fiscal deficit before interest payments by 13.4% of GDP between 2009 and 2012.

The European Union, International Monetary Fund and the European Central Bank are the main creditors to the Greek government. They are known as the EU-IMF-ECB troika
Fiscal austerity means contractionary fiscal policy measures in the form of higher taxes and/or cuts in planned government (public) spending. In Greece in 2010, the country was forced to agree a Euro 110bn emergency bailout and introduce an austerity budget. These measures included a VAT rise from 19% to 23%, higher duties on fuel, alcohol and cigarettes, an increase in the retirement age, a public sector pay freeze and a freeze on the size of the basic state pension.
There is a fierce debate in economics about the most effective ways to address the problems caused by high levels of government debt. Many economists including Nobel-winner Joseph Stiglitz argue that contractionary policies make the debt problem worse and that sustained growth is the best pathway out of a debt crisis.
Greece is also seeking to implement structural economic reforms as part of their bail-out package. Structural economic reforms have included:
    • Pension reforms including raising the official state retirement age
    • Privatisation of state assets both to raise revenue and to increase competition
    • Cuts in the national minimum wage
    • Measures to reduce entry barriers to certain occupations / professions including transport
    • Cutting taxes on employing workers to boost employment
    • Making the Greek judicial system more efficient
    • Cutting red tape for businesses to promote investment
    • Stronger measures to tackle tax evasion by individuals and businesses
The key issue is whether these structural supply-side reforms will be sufficient to improve competitiveness and generate the minimum growth that Greece needs to break out of their debt trap?

Understanding the Economic Cycle

Introduction

All countries experience regular ups and downs in the growth of output, jobs, income and spending. These fluctuations form what is known as the economic or business cycle.
Boom
boom occurs when real national output is rising at a rate faster than the trend rate of growth. Some of the characteristics of a boom include:
  • A fast growth of consumption helped by rising real incomes, strong confidence and a surge in house prices and other forms of personal wealth
  • A pick up in the demand for capital goods as businesses invest in extra capacity to meet rising demand and to make higher profits
  • More jobs and falling unemployment and higher real wages for people in work
  • High demand for imports which may cause the economy to run a larger trade deficit because it cannot supply all of the goods and services that consumers are buying
  • Government tax revenues will be rising as people earn and spend more and companies are making larger profits – this gives the government money to increase spending in priority areas such as education, the environment, health and transport
  • An increase in inflationary pressures if the economy overheats and has a positive output gap.
The UK enjoyed sustained growth over the last fifteen from 1993 through to the end of 2008 but for better examples of booming countries we have to look overseas. The obvious example is China whose growth has been astonishing. And many other emerging market countries have experienced a decade or more of phenomenally rapid increases in the size of their economies. The BRIC countries have interested economists interested in understanding their fast rates of growth and development. In addition to China, the BRIC nations include BrazilRussia and India.
Slowdown
Recession
Recession and rising unemployment
“There is a risk is that productive capacity in the UK economy could be permanently lost, as temporary job losses morph into long-term unemployment due to job-seekers losing skills and dropping out of the labour market”
Source: IMF Blog, August 2011

recession means a fall in the level of national output i.e. a period when growth is negative, leading to a contraction in employment , incomes and profits .
  • The simple definition:
    • A fall in real GDP for two consecutive quarters i.e. six months
  • The more detailed definition:
    • A recession is a significant decline in economic activity spread across the economy, lasting more than a few months, normally visible in real GDP, real income, employment, industrial production, and wholesale-retail sales.
There are many symptoms of a recession – here is a selection of key indicators:
  • A fall in purchases of components and raw materials from supply-chain businesses
  • Rising unemployment and fewer job vacancies
  • A rise in the number of business failures including high profile names such as Woolworths
  • A decline in consumer and business confidence
  • A contraction in consumer spending & a rise in the percentage of income saved
  • A drop in the value of exports and imports of goods and services
  • Deep price discounts offered by businesses in a bid to sell excess stocks
  • Heavy de-stocking as businesses look to cut unsold stocks when demand is weak
  • Government tax revenues are falling and welfare spending is rising
  • The budget (fiscal) deficit is rising quickly
The difference between a recession and a depression
  • slump or a depression is a prolonged and deep recession leading to a significant fall in output and average living standards
  • A depression is where real GDP falls by more than 10% from the peak of the cycle to the trough.
What are the main causes of a recession?
  • Recessions are unusual. To some economists they are an inevitable feature of a market economy because of the cyclical nature of output, demand and employment.
  • Every recession is different! It is undeniable that the global credit crunch has been hugely significant in causing the downturn even though macroeconomic policy has tried hard to prevent it.
The 2009 recession was the result of a combination of domestic and external economic factors and forces:
  • The collapse of the British property boom – falling house prices hit wealth and led to a large contraction in new house building
  • Reductions in real disposable incomes due to wages rising less quickly than prices
  • A sharp fall in consumer confidence – made worse by rising unemployment – leading to an increase in household saving – Keynes called this the ‘paradox of thrift.’ (see the chapter on Keynesian economics)
  • External events – such as recession in the UK’s major trading partners including the USA (which accounts for 15% of UK trade) and the Euro Area (which has 55% of UK trade)
  • UK exports declined because of recession in major trading partners and this hit manufacturing industry and other businesses that supply export firms
  • Cut-backs in production have led to a negative multiplier effect causing a decline in demand for consumer services and lower sales and profits for supply-chain businesses
  • The credit crunch caused the supply of credit to dry up affecting many businesses and home-owners
  • Falling profits and weaker demand has caused a fall in business sector capital investment – known as the negative accelerator effect.
  • Unemployment has started to rise early in the downturn – a reflection of our flexible labour market and sticky wages
An important evaluation point is that, in a recession, some businesses are affected more than others.
The extent of the effects will depend on the type of business, the market it operates in and the nature of the product sold
When real incomes are falling, we would expect to see a decline in demand for products with a highincome elasticity of demand – typically these goods and services are regarded as luxury items by consumers, things that they might choose to do without when the economy is having a bad time.
Demand for products with negative income elasticity (i.e. inferior goods) might rise during a recession!
Slow Recovery for the UK
The British economy which contracted 6.4pc in the downturn, has rebounded 2.5pc, and is still 3.9pc below its peak. This recovery is taking longer to take root than from any 20th Century recession bar the Great Depression
Source: News reports, August 2011
Recovery
  • A recovery occurs when real national output picks up from the trough reached at the low point of the recession.
  • The pace of recovery depends on how quickly AD starts to rise after a downturn. And, the extent to which producers raise output and rebuild their stock levels in anticipation of a rise in demand
  • The state of business confidence plays a key role here. Any recovery might be subdued if businesses anticipate that a recovery will be temporary or weak in scale.
A recovery might follow a deliberate attempt to stimulate demand. In the UK a number of strategies have been used to boost confidence and demand and prevent the recession turning into a damaging depression:
  • Cuts in interest rates – the policy interest rate fell to 0.5% in the Autumn of 2008 and they have stayed at this low level ever since (0.5% at the time of writing in August 2012)
  • A rise in government borrowing – the budget deficit rose above £150bn in 2009 and government borrowing is likely to remain high for some time to come despite attempts to cut it
  • A policy of quantitative easing (QE) by the Bank of England to pump more money into the banking system in a bid to increase the supply of loans – now worth more than £325 billion.
  • A temporary cut in the rate of VAT from 17.5% to 15% (now reversed – VAT rose to 20% in 2011)
  • The launch of a car scrappage scheme for older cars worth up to £2000 per car and a consumer subsidy for households replacing their old boilers.

Why has the economic recovery in the UK economy been so weak?
The year 2009 saw the UK economy suffer a deep recession with a fall in real GDP of 4.4% and a steep rise in the unemployment rate. There was an encouraging recovery in national output in 2009 with real GDP growing close to the estimated trend rate of growth. 
Since then however the pace of expansion in the UK economy has slowed down with growth of only 0.7% in 2011 and even weaker growth forecast for 2012. Indeed in the 2nd quarter of 2012, data showed that the British economy had fallen into a second recession – known as a double-dip. 
The level of real GDP remains well below the peak reached at the end of the last economic cycle. Many commentators are forecasting that recovery will continue to be slow in the next couple of years and this poses big risks for households, businesses and the government.

Why is the UK finding it hard to achieve a decent recovery in output and jobs? As always when we study macroeconomics, there are many factors at work. The UK is an open economy and our fortunes are affected not just by domestic events and policies but also what is happening in the global system.
Why is GDP growth so difficult to forecast?
Why is GDP growth so difficult to forecast?
When economists make forecasts about the future path for an economy they have to accept the inevitability of forecast errors. Conditions in the economy are always changing and no macroeconomic model can hope to cope with the fluctuations and volatility of indicators such as inflation, exchange rates and global commodity prices. GDP growth is hard to forecast – the chart above is the one produced by the Bank of England when they publish their quarterly Inflation Report. The projection area is their forecast, notice how the uncertainty grows as we move further from the present. In 2014, the range of probabilities for real GDP growth in the UK stretches from -1% (recession) to over 5% (very strong growth). The graph above is a probability fan chart, the darker the area, the higher is the probability attached to the outcome.


IGCSE A level notes, Price mechanism

Introduction

Adam Smith’s Invisible Hand
Adam Smith, one of the Founding Fathers of economics described the “invisible hand of the price mechanism” in which the hidden-hand of the market operating in a competitive market through the pursuit of self-interest allocated resources in society’s best interest.
This remains a view held by free-market economists who believe in the virtues of an economy with minimalgovernment intervention.
The price mechanism describes the means by which millions of decisions taken by consumers and businesses interact to determine the allocation of scarce resources between competing uses
The price mechanism plays three important functions in a market:
1/ Signalling function
  • Prices perform a signalling function – they adjust to demonstrate where resources are required, and where they are not
  • Prices rise and fall to reflect scarcities and surpluses
  • If prices are rising because of high demand from consumers, this is a signal to suppliers to expand production to meet the higher demand
  • If there is excess supply in the market the price mechanism will help to eliminate a surplus of a good by allowing the market price to fall.
price mechanism
In the example on the right, an increase in market supply causes a fall in the relative prices of digital cameras and prompts an expansion along the market demand curve
2/ Transmission of preferences
  • Through their choices consumers send information to producers about the changing nature of needs and wants
  • Higher prices act as an incentive to raise output because the supplier stands to make a better profit.
  • When demand is weaker in a recession then supply contracts as producers cut back on output.
One of the features of a market economy system is that decision-making is decentralised i.e. there is no single body responsible for deciding what is to be produced and in what quantities. This is a remarkable feature of an organic market system.
3/ Rationing function
  • Prices serve to ration scarce resources when demand in a market outstrips supply.
  • When there is a shortage, the price is bid up – leaving only those with the willingness and ability to pay to purchase the product. Be it the demand for tickets among England supporters for an Ashes cricket series or the demand for a rare antique, the market price acts a rationing device to equate demand with supply.
  • The popularity of auctions as a means of allocating resources is worth considering as a means of allocating resources and clearing a market.
Mixed and Command Economies and Prices
  • Most economies are mixed economies, comprising not only a market sector, but also a non-market sector, where the government (or state) uses planning to provide public goods and services such as police, roads and merit goods such as education, libraries and health.
  • In a command economy, planning directs resources to where the state thinks there is greatest need. Following the collapse of communism in the late 1980s and early 1990s, the market-based economy is now the dominant system in most countries – even though we are increasingly aware of manyimperfections in the operation of the market.
Prices and incentives
  • Incentives matter! For competitive markets to work efficiently all ‘economic agents’ (i.e. consumers and producers) must respond to appropriate price signals in the market.
  • Market failure occurs when the signalling and incentive functions of the price mechanism fail to operate optimally leading to a loss of economic and social welfare. For example, the market may fail to take into account the external costs and benefits arising from production and consumption.  Consumer preferences for goods and services may be based on imperfect information on the costs and benefits of a particular decision to buy and consume a product.
Secondary markets
  • Secondary markets occur when buyers and sellers are prepared to use a second market to re-sell items that have already been purchased.
  • Perhaps the best example is the secondary market in tickets for concerts and sporting-events.
Do ticket touts provide a valuable service to a market? Or should they be banned by law?
Government intervention in the market mechanism
  • Often the incentives that consumers and producers have can be changed by government intervention in markets
  • For example a change in relative prices brought about by the introduction of government subsidies and taxation.
Government subsidies and taxation
Agents may not always respond to incentives in the manner in which textbook economics suggests.
The “law of unintended consequences” encapsulates the idea that government intervention can often be misguided of have unintended consequences! (See the final chapter on government failure)

Introduction

Finite resources and sustainability
There are only a finite - or limited - number of workers, machines, acres of land and reserves of oil and other natural resources on the earth.  Because most resources are finite, we cannot produce an unlimited number of different goods and services. Indeed by supplying more for an ever-growing and richer population we are in danger of destroying the natural resources of the planet.
Our ecological footprint affects the sustainability of economies and has huge implications for future living standards. Environmental pressure groups such as Friends of the Earth and Greenpeace seek to highlight the permanent damage to the stock of natural resources and the dangers from rapid development and the effects of global warming.
The Worldwide Fund for Nature has claimed that the natural world is being degraded "at a rate unprecedented in human history" and has warned that if demand continues at the current rate, two planets will be needed to meet global demand by 2050. Resources are being consumed faster than the planet can replace them
One issue is the threat posed by the shortage of water as the world’s demand for household and commercial use continues to grow each year. Experts predict that half the world's population will be affected by water shortages in just 20 years' time. During the 20th century the world population increased fourfold, but the amount of freshwater that it used increased nine times over. Already 2.8 billion people live in areas of high water stress. For more on this issue visit the World Heath Organisation’s special web site on water scarcity.
At the heart of improving resource sustainability is the idea of de-coupling – a process of trying to increase the efficiency with which resources are used and breaking the link between increasing demand and resource depletion.
Factors of Production
Land:
  • Land includes all natural physical resources – e.g. fertile farm land, the benefits from a temperate climate or the harnessing of wind power and solar power and other forms of renewable energy.
  • Some nations are richly endowed with natural resources and then specialise in the their extraction and production – for example – the high productivity of the vast expanse of farm land in Canada and the United States and the oil sands in Alberta, Canada. Other countries are reliant on importing these resources.
Labour:
  • Labour is the human input into production.
  • An increase in the size and the quality of the labour force is vital if a country wants to achievegrowth. In recent years the issue of the migration of labour has become important. Can migrant workers help to solve labour shortages? What are the long-term effects on the countries who suffer a drain or loss of workers through migration?
Capital:
  • Capital goods are used to produce other consumer goods and services in the future
  • Fixed capital includes machinery, equipment, new technology, factories and other buildings
  • Working capital means stocks of finished and semi-finished goods (or components) that will be either consumed in the near future or will be made into consumer goods
New items of capital machinery, buildings or technology are used to boost the productivity of labour. For example, improved technology in farming has vastly increased productivity and allowed millions of people to move from working on the land into more valuable jobs in other industries.
  Infrastructure – a crucial type of capital
Examples of infrastructure include road & rail networks; airports & docks; telecommunications e.g. cables and satellites to enable web access.
The World Bank regards infrastructure as an essential pillar for economic growth in developing countries. India is often cited as a country whose growth prospects are being limited by weaknesses in national infrastructure.
Entrepreneurship
An entrepreneur is an individual who supplies products to a market to make a profit.
Entrepreneurs will usually invest their own financial capital in a business and take on the risks. Their main reward is the profit made from running the business.
Renewable and Finite Resources
Renewable resources are commodities such as solar energy, oxygen, biomass, fish stocks or forestry that is inexhaustible or replaceable over time providing that the rate of extraction of the resource is less than the natural rate at which the resource renews itself. (This is important!)

This is a key issue in environmental economics, for example the over-extraction of fish stocks, and theglobal risks of permanent water shortages resulting
Finite resources cannot be renewed. For example with plastics, crude oil, coal, natural gas and other items produced from fossil fuels, no mechanisms exist to replenish them.
