What is meant by financial sector stability?
Financial stability is considered to be a state in which the financial system i. e. the key financial markets and financial institutional system (banking) is resistant to economic shocks such as a global recession.
A stable financial system is capable of efficiently allocating resources, managing risks and arranging payments. When in financial stability, the system will absorb external and internal shocks using self-corrective mechanisms.
Financial stability is considered paramount for economic growth as most transactions in the modern economy are made through the financial system.
Financial instability leads to banks becoming unwilling to fund profitable projects and reluctant to distribute credit. This could lead to bank runs, hyperinflation or a stock market crash of the bank. Financial stability can also have a severe adverse impact on consumer and business confidence.
The recent banking crisis and 'credit crunch' that accompanied the 2008 global recession stimulated the creation of the Financial Policy Committee (FPC) in the UK. The role of the FPC is to identify, monitor and taking action to remove or reduce systemic risks with a view to protecting and enhancing the resilience of the UK financial system.

The Law of Diminishing Returns (A2 Microeconomics)
The law of diminishing returns relies on the assumption that capital is a fixed factor. It states that as a firm increases the amount of inputs of a variable factor (such as labour), it will gradually derive less additional output per unit of labour for each further increase. This is a result of the fixed factor of production, which limits the capacity of cost efficient production. For example if a manufacturing firms owns 100 sewing machines, as the number of machine operators employed by the firm passes 100 and employees are required to share machines the output per worker will begin to fall.
As it becomes more expensive to produce each additional unit of output, marginal cost (MC) and average variable cost (AVC) will start to rise.
Eventually, the rise in AVC will exceed the fall in average fixed cost (AFC) which generally occurs as fixed costs can be spread to a larger amount of units of output. When this happens, average total cost (AC) will also start to rise.

Here, where MC is below AC, AC must be falling. This is because an additional unit of output that is cheaper than the average unit cost will pull down the average cost of production. Once the MC curve meets the AC curve, average costs begin to rise as they are exceeded by the marginal cost of output. If an additional unit of output is more expensive to produce that the average cost, the new average cost including this additional unit will be greater.
This relationship results in the MC curve cutting the AC curve at its lowest point. This is where costs of production are at a minimum. Profit maximising firms will aim to produce at this point.

Balanced Budget Fiscal Expansion (A2 Macroeconomics)
The idea of a balanced budget fiscal expansion relies on the positive multiplier effect being greater than one. Generally, unless the economy is at or close to full capacity this is likely to be the case as a result of its reduction in unemployment.
For those currently studying at A2 through OCR, balanced budget fiscal expansion is mentioned in Extract 1 of the case study for The Global Economy module. The IMF recommended that the UK pursue a balanced budget fiscal expansion to increase growth. This form of fiscal expansion, if successful, would stimulate an increase in aggregate demand without compromising the government's Deficit Reduction Plan.

Is 'free' trade hindering the development of poor countries?
However, the view that free trade will lead the development of a nation is a highly controversial one. Strong arguments exist, stating that trade is often unfair to developing countries as stronger economies, firms and organisations control markets by following protectionist strategies such as tariffs and subsidisation and by controlling commodity prices.
An example of this occurring is in the cocoa industry in Ghana where foreign commodity traders such as buyers for MNCs like Nestle and Cadbury trade in future markets (i.e. they buy supplies now to ensure delivery in 3 to 6 months). A downward pressure is put on cocoa prices due to competition from other exporting nations. Due to this, commodity prices are volatile which results in irregular income for workers and uncertain tax returns for governments of developing nations.
The prices of commodities are also volatile as a result of their price inelastic demand and supply. A price inelastic demand is caused by most commodities being necessities rather than luxury goods and due to their lack of substitute goods. Commodities also have a price inelastic supply due to their relatively long period of time taken to excavate and the limit to their potential supply. This means that a small change in quantity demanded or supplied can radically affect their price and so make predicting revenue generated from their export difficult.
In Ghana, as with many other developing nations, much of the nations income therefore depends on the actions of powerful MNCs from the developed world. Such as relationship is described as neo-colonial meaning that countries remain under control of overseas countries indirectly - despite them supposedly being independent.
Further injustice: how 'free' is free trade?
This seems like a ridiculous question but, unfortunately, as developing countries are pressured into completely liberalising their markets the same is not being done to wealthier and more powerful nations.
In the EU free trade occurs internally. Externally, however, traders are faced with high import tariffs. Most of the processing and packaging of cocoa is completed in Europe as a result of the occurrence of tariff escalation. EU tariff imports are much higher for processed cocoa than for raw cocoa beans and as a result Ghana is forced to export the raw beans and lose out on the value added by processing them, meaning that workers have little opportunity to earn higher incomes. Through this process strong economies are able to maintain poorer countries in a state of under development and prevent large scale industrialisation. Instead high income countries purchase cheap commodities from the developing world and add value to them before exporting them back as high value, manufactured goods. Developing nations can become stuck in the primary sector, a constraint on development. This is known as the resource curse and is considered to be a curse because resources are exhaustible and currently depletion rates are unsustainable.
This supports A.G Frank's Dependency Theory which splits the world into an economically developed core and and underdeveloped periphery. The theory states that developed countries keep developing countries in a state of under development by exploiting its raw materials and selling it costly manufactured goods, technology and credit. Developing countries are exporting low value goods and importing high value goods. This results in a poor terms of trade. As the periphery remains underdeveloped, its most skilled workers move to the developed core creating a brain drain, further exacerbating the problem.
The role of the World Trade Organisation (WTO)
The purpose of the WTO is to promote global free trade. Despite pressurising developing nations into completely liberalising trade, the WTO has not been successful in removing the EU Common Agricultural Policy (CAP) which discriminates against farmers in developing countries by undermining their natural price advantage and flooding their economies with heavily subsided imports. Critics of the WTO describe it as an organisation that favours the wealthy nations that were responsible for its creation by pressuring poorer nations into unfair trade agreements.

Referring back to the example of Ghana, in 1995 Ghana joined the WTO in an attempt to increase its global trade. Instead the nation was faced with the joining condition that farms in Ghana should no longer be subsidised by the government (which until then had occurred to encourage farmers to continue supplying food for the country's growing cities). As a result, local farmers lost out to cheaper competition from EU imported goods that had been subsidised in their country of production.
It cannot be denied that free trade between nations generates wealth, but is the benefit really being felt in the worlds poorer nations or is the liberalisation of markets in fact acting as a constraint to development?

Exchange Rates: Fixed vs Floating (A2 Macroeconomics)
The Free Floating Exchange Rate
A free floating exchange rate is a system whereby the price of one currency expressed in terms of another is determined by the forces of demand and supply.
Advantages:
- A floating exchange rate means that a government can have a larger focus on achieving other macroeconomic objectives. For example, there is no need to set interest rates to achieve an exchange rate target so interest rates can be used to achieve price stability or encourage investment.
- Automatic adjustment should ensure a Balance of Payments equilibrium is achieved. For example, if a country has a balance of payments deficit then the currency should depreciate. This is because a deficit means that imports will be greater than exports. As a result, the supply of the nations currency will exceed its demand on the FOREX market which will cause the value of the currency to depreciate. This will make exports cheaper (and so raise demand) and imports more expensive (reducing demand), eliminating the B of P deficit.
- It may be easier to adjust to external economic shocks such as a global recession. A global recession would reduce the demand for exports, causing reduced demand for currency on the FOREX markets and lead to a depreciation in the value of the currency, lowering the price of exports and making them more attractive.
- A changing value of a currency may result in consumer uncertainty. Exporters may be unsure of how much money they will receive when they sell abroad and importers may not know exactly how much it is going to cost to import a foreign good.
- The freedom to set domestic policy does not guarantee that price stability will be prioritised over other objectives. Automatic adjustment mechanisms may lead to governments pursuing short-term economic growth at the expense of higher inflation.
- The floating exchange rate can be inflationary by allowing import prices to rise as the exchange rate depreciates. This particularly an issue for countries who depend on imports for the provision of certain goods such as exotic foods.
In a fixed exchange rate system, the government intervenes in the currency market so that the exchange rate stays close to an exchange rate target.
Advantages:
- A fixed exchange rate provides certainty for traders, investors and consumers by allowing the price of imports and exports to remain more stable. Some economists argue that this will result in higher levels of trade and investment.
- Fixed exchange rates can impose financial discipline on domestic firms to keep their costs under control in order to remain competitive in international markets. This helps the government maintain low inflation, which in the long run should reduce interest rates and stimulate trade and investment.
- A fixed exchange rate reduces the costs of international trade to firms by removing the need of hedging (limiting the risk that losses are made in changes in the price of currencies by buying currencies in future markets).
- It may be difficult to work out the initial fixing of the rate of exchange. If it is fixed at a rate too high, exports will remain relatively expensive and imports cheap. This will result in a long term loss in international competitiveness by domestic firms and a poor position in the current account of the balance of payments.
- In order to fix the exchange rate, the government will need to maintain a high level of foreign currency reserves in order to intervene on the FOREX market. This incurs an opportunity cost. In addition, whilst maintaining the exchange at a fixed rate, other macroeconomic policy objectives may be sacrificed. For example, governments may alter interest rates in order to influence the rate of exchange, conflicting with with the objective of maintaining price stability.
- A fixing of the exchange rate could result in retaliation by other nations. Retaliation may take the form of protectionist measures such as trade barriers against imports from domestic firms. This will increase the price of exports, thus rendering the fixed rate ineffective in increasing trade.

Economic Systems (AS Revision)
The Market Economy
A market economy is defined as "an economic system whereby resources are allocated through the market forces of supply and demand". In a market economy the consumer is sovereign; the demand by consumers controls the output of produces and therefore the allocation of resources. This takes place through the price mechanism where firms respond to consumer choice through the free movement of price in response to demand and supply. The government will have little involvement in this process, with their main roles involving legislation and the protection of property rights. The USA may be considered the closest to a free market, however governments still play roles in providing some public services.In a market economy the level of consumer choice will be dependent upon their income. The higher the income of the consumer, the greater their choice. This could lead to social inequality by excluding those on low incomes from various goods and services. However, a free market economy may be seen as beneficial to the consumer a competition between producers will be high. This will encourage allocative and productive efficiency in order to be price competitive as well as encouraging research and development by firms to compete on non-price factors such as quality.
Command/ Centrally Planned Economies
A command economy is "an economic system where government, through a planning process, allocates resources in society". Examples of command economies include North Korea and Cuba. It is the governments that own the majority of resources and it is their role to allocate these resources. Both wages and prices of essential items are controlled by the state. Governments of command economy's set targets for production in long term plans that often aim for a high rate of growth in output.Arguments against command economies include a lack of consumer choice. Not only are consumers exposed to a lack of variety of goods and services, but as workers they are also allocated jobs by the state.With equal choice and opportunity, workers have little incentive to improve. The lack of competition between producers removes the incentive to achieve economic efficiency, and also likely to result in a lower quality of goods and services that are provided.
The Mixed Economy
A mixed economy is defined as "an economic system in which resources are allocated though a mixture of the free market and direct public sector involvement". The UK is an example of a mixed economy, where a Private Sector and Public Sector exists. The private sector allocates resources through the market forces of supply and demand, but with government intervention in markets that would fail if left to the free market. The government allocates resources in the Public Sector, which includes services such as education, healthcare and the emergency services. If governments intervene effectively and to the correct extent, a mixed economy may considered to be the best of both worlds. However in some cases, government intervention in markets is unable to correct the existing the market failure and may even make the situation worse resulting in government failure.

Measuring Inflation - What you need to know at AS (Revision)
How inflation works can be shown through a trip to the supermarket. I head to Sainsbury's and purchase a trolley full of a range of goods for £100. I then return to the supermarket a year later and purchase the same items, this time coming to a total of £105. I have experienced the effects of a 5% inflation rate. If I am to purchase these goods I will have to spend an extra £5 to what I did last year or I will need to remove an item from my trolley (shoplifting is against the law, no kleptomaniacs please). Inflation thus leads to higher prices and lower purchasing power. It tends to be a monetary phenomenon caused by a country printing more money than is justified by the country's wealth.- CPI is regarded to be more accurate. It's maths is truer and reflects to the inflation that a lot more people experience.
- The RPI does not meet international standards. It doesn't match what other countries do.
- The CPI excludes all housing costs including mortgages, interest payments and council tax. It also excludes the road fund licence and TV licence.
- Both do not respond to changes in quality. Although the price of a good or service may rise, this may be accompanied by an improvement in quality. In this respect, both measures may over-estimate inflation.
- Both do not take into account the prices of second hand goods.

Is mercantilism really a thing of the past?
Put simply, mercantilism is the belief in the benefits of profitable trading. It involves maximising net inflow of foreign exchange (traditionally in the forms of gold and silver) by restraining imports and encouraging exports. It serves the interests of producers whose actions are protected and encouraged by the national government. Core to the support of of mercantilism is another new term - Bullionism. Bullionism is an economic theory that defines wealth by the amount of precious metals owned.
Mercantilism was most popular in the 16th to 18th centuries (know as the mercantile era). Mercantile firms would be protected against foreign and domestic competition through policies set by national government. Such policies included the provision of capital, the establishment of monopolies and the implement of tariffs and/or quotas to competing imported goods.
An example of extremity of mercantilism policy can be seen the Hudson's Bay Company, who traded beaver fur. In 1670 King Charles II granted the company a charter which gave Hudson's Bay Company a monopoly status in England and sole trade of the Hudson Straight territory. The charter also made the three founders of the company "the true and absolute lords and proprietors" of the Hudson's Bay area- an area which roughly took up 40% of Canada. The firm were the unofficial government of the area and had the power to pass laws, fight wars and issued its own currency. It has territorial control of the area for 200 years before being sold to the Dominion of Canada. The power given to the trading monopolies during the mercantile era, in my opinion, makes the power of modern day large MNCs seem slightly less threatening.The end of the mercantile era is seen to be at around the time of the publishing of Adam Smith's The Wealth of Nations, which is considered to be at the base of the modern economic theory. The book argued that such a relationship between government and markets was a harm to the general population. Instead, Smith promoted policy based around free markets and the liberalisation of trade. He argued that mercantilism reduces competition and so acts as a drag on economic development. By the middle of the 19th century, this opinion had caught on a Britain had embraced the idea of free trade.
More recently, mercantilism is seen as nothing more than a part of economic history. However, arguments for the mercantilism continuing to take place exist, particularly when looking at the case of China.
After China opened its doors to free trade in 2001, Chinese economic policy focused on encouraging FDI by MNCs through the promise of cheap labour a special export zones which contained lower tax rates. However, in 2006 China chose to move attraction of investment from foreign firms to investment into Chinese firms. It is the methods that China has taken to achieve this that are now being considered to be neo mercantilism. Policies have included actions to spur exports while reduce imports such as currency manipulation, high tariffs and tax incentives for exports. There are also arguments that China is now discriminating against foreign firms through policies such as land grants and tax incentives to Chinese firms, cash subsidies and controls on foreign purchases designed to force technology transfer into China.
The question is, is this really a new era of mercantilism in China or is the country simply showing justified levels of support to its growing domestic firms?

Whats that? WhatsApp. Is it worth the $19bn takeover?

Mark Zuckerburg spoke on behalf of Facebook at a press conference in Barcelona yesterday and believes that WhatsApp is a "rare platform that has the potential to reach out to 1 billion mobile users". The real majesty of web dynamics and most obvious is the colossal global reach at nearly zero marginal costs. Whatsapp has around 50 employees. It has no marketing costs. No Washington lobbyists. No stores. No global campus. No sponsorship of the local symphony. With the introduction of voice calling becoming available in the next few months, at what is said to be free, potential add-ons to this feature are endless. Adaptations of the iPhone's FaceTime or extra emoticons at low prices will help create the revenue the company is needing and make the sum of $19bn seem a lot more reasonable. What most new users don't realise, like myself, is only the first year of WhatsApp is free. After 12 months your account will expire and you will be asked to pay prior to your subscription end date.Thursday, 20 February 2014
Fiscal Multipliers (A2 Macroeconomics)
A fiscal multiplier measures the final change in national income (real GDP) that results from a deliberate change in either government spending and/or taxation. For example, if a government spends £1 million on a project that causes GDP to increase by £1.5 million then the fiscal multiplier for this project was 1.5. Several factors affect the size of the fiscal multiplier. Some of these include:
- The nature of the fiscal policy. In terms of fiscal stimulus, Keynesian economists believe that the size of the fiscal multiplier effect is higher for government spending than for tax cuts.
- The Availability of credit. As demand rises, it will be necessary for credit to be easily available to those firms that require it in order to fund production increases and capital investment.
- Monetary Policy. For example, government spending through borrowing that leads to higher interest rates may result in a smaller fiscal multiplier as firms may feel less inclined to borrow and consumers may increase their marginal propensity to save (MPS).
- Levels of international trade. The more open an economy is, the greater the extent to which higher government spending or tax cuts will feed into rising demand for imported goods and services, lowering the impact on domestic GDP.
- Confidence. Consumers MPS might be higher if there is uncertainty about job prospects, future income and inflation.
