Causes of Long-Run Economic Growth (Macroeconomics)
I'm fully aware that there is already about a post about economic growth, however i want to use this one to focus in specifically on economic growth in the long run. Long run economic growth isn't so dependent on aggregate demand changes, but a lot more dependent on changes to the long run aggregate supply curve. A shift the the right of the LRAS curve is a sign of long run economic growth.
Increases in LRAS on a diagram resemble an increase in the economies capacity to supply goods and services, and for this increase to happen there needs to be there needs to be either an increase in the quantity of the factors of production or an increase in the quality of them. The most important factor of production is undoubtedly the labor force, so therefore these are what i'll focus on.
There are few ways to increase the quantity of the labor force. First, increasing the size of the population. This is difficult to achieve artificially as it is influenced a lot by social and cultural factors. The second way is to increase the labor force participation rate. This is a measure of the proportion of the population able to work and either in employment or actively seeking it. Changes to the taxation and benefit system can influence this by making it more appealing for people to actually start seeking work and get into employment. The final way is to increase the flow of migrant workers, better known as immigration. Joining groups such as the EU allows free-er movement of labor among countries which can increase the population. However, immigration may only be temporary and therefore there may be no long-term increase in the productive capacity.
It is also possible to improve the quality of the labor force. The first method is through education and training. It improves each workers productive potential allowing each worker to make more due to the better knowledge and skills gained through the education. As economic growth occurs, economies tend to move away from primary and secondary industries and onto tertiary industries. It is important to equip the population with the skills to take part in the tertiary sector so the economy can complete the transition away from primary and secondary sector industries.
There we go.. to summarize: The quantity or the quality of the factors of production are required to increase for the economies productive capacity to increase which then causes economic growth in the long run. Thanks for reading.

Absolute and Comparative Advantage (Macroeconomics)
Today we come to the theories of comparative advantage and absolute advantage. Lets start with 'text-book' definitions:
- Absolute advantage - A country is said to have an absolute advantage over another country when it can produce a good at a lower cost (using less resources).
- Comparative advantage - A country is said to have a comparative advantage over another country with regard to a product which it can produce at a lower opportunity cost expressed in terms of alternative goods forgone.
An example now. Take two countries, country A and B and lets look at their production of apples and televisions (crazy examples, but hey ho!). When both countries use 50% of their resources producing each good, country A can produce 5 apples and 15 televisions and Country B can produce 3 apples and 12 televisions. The opportunity cost of country A producing bananas in terms of televisions is 3. For every banana they are giving up the chance to produced 3 televisions. For Country B the opportunity cost is 4. The opportunity cost of country A producing televisions in terms of bananas is 1/3 and the opportunity cost for country B is 1/4.
Looking at these figures, Country A has the lowest opportunity cost for producing bananas, therefore they have the comparative advantage in producing bananas, leaving country B to produce television.
Simple eh? Nope, it's a difficult concept to get your head around, but that is the basics. Thanks for reading and sorry about the delay.

Exchange Rates (Macroeconomics)
Exchange rates are something that affects all of us, be it directly or indirectly. Exchange rates are basically the value of a currency compared to that of another currency. They fluctuate a lot, which leads to price changes.
I'll be using the Sterling (£) in my examples throughout. Firstly, let's look at what determines the value of a currency. The value of the £ is determined by the free market, so therefore the powers of demand and supply dictate the value of the £. The majority of the demand for the £ will come from trading partners demanding the U.K's exports and therefore needing the £ to buy them. The majority of the supply of the £ comes from us demanding foreign imports, and needing to sell the £ to get foreign currency to buy the imports.
An increase in the demand for the £ will increase the value compared to other currencies. This is often referred to as a "strengthening of the £" or an "appreciation". Obviously, a fall in demand for the £ will have the opposite effect. An increase in the supply of the £ will decrease the value compared to other currencies. This is often known as a "weakening of the £" or a "depreciation". A decrease in supply will have the opposite effect, raising the value.
Another key factor that influences the demand and supply of the £ is interest rates. If interest rates in the U.K. are high, then we will see a high demand for the £ as people will make a better return off of it in U.K. banks. This will increase the value of the currency. A decrease in interest rates will see money flow out of the U.K. in search of a better return on their investment and therefore demand and the value of the £ will fall.
There are two different exchange rate mechanisms. The first one is the floating mechanism. This is when the value of the currency is determined by the free market - the powers of demand and supply. The advantage of this mechanism is that theoretically the exchange rate should automatically adjust which will eliminate any imbalances withing the Balance of Payments. The other is the fixed mechanism. This is when the exchange rate is fixed and determined by the government or central bank of a country. The bonus to this is that it gives more stability to the value of the currency but runs the risk of goods becoming to un-competitive if it's too high or the market can be flooded if it's too low.
That's the lot for exchange rates, thanks. Also, any requests for what to come next? Post it in comments and ill see what i can do. Thanks for reading, follow the blog if you enjoy!

Monetary Policy (Macroeconomics)
Monetary policy, liked with fiscal policy is another tool the government can use to control the economy. Monetary policy involves the use of exchange rates, interest rates and the money supply to manage the economy.
Firstly, interest rates. These are set by the MPC and are mainly used in the U.K to try and achieve the inflation target of 2.0%. The theory is that a reduction in interest rates will give consumers more disposable income through lower loan repayments and this will boost the consumption factor of Aggregate Demand. Also, it should make businesses take out loans more willingly as borrowing money becomes cheaper and thus the investment factor of Aggregate Demand will rise also. Overall, a fall in in interest rates should create a rise in the real GDP of the country. It works the opposite way with a rise in interest rates, this should reduce the real GDP of the country as well as control inflation.
Interest rate changes also effect the Balance of Payments. Interest rates in the U.K. rising will cause a flow of 'hot money' into the economy as people will benefit from the higher returns of putting their money in the U.K. This flow will increase the demand for the pound, so the value will appreciate. The knock on effect of an appreciation in the value of the pound is that our exports become more expensive and it becomes cheaper for us to import goods. This will worsen the Balance of Payments. Obviously, the opposite will occur with a fall in interest rates.
Exchange rates was another tool under the title of 'Monetary Policy'. By managing the exchange rate, the Bank of England can buy and sell pounds to influence the exchange rate. This will control the competitiveness of U.K. exports and therefore help control the Balance of Payments. However, the government doesn't generally take this approach as they let the free market determine the value of the pound. One instance where this is sometimes done is in China.
The final tool under the 'Monetary Policy' heading was the money supply. This is where the government can increase or decrease the amount of money in the economy. The idea behind increasing the money supply is that it should stimulate Aggregate Demand as people have more money to spend and businesses have more money to invest. However, this method is very inflationary and is widely avoided. Decreasing the money supply will have the opposite effect to the above.
That's it, the three parts involved in the 'Monetary Policy' tool the government has at its disposal. Thanks for reading.

Fiscal Policy (Macroeconomics)
Right, this post will discuss the basics of fiscal policy. Basically, fiscal policies are any policies that relate to government spending and government taxation - the government uses these two tools to manage the economy and redistribute resources.
The budget plays a big part in fiscal policies. Depending on what fiscal policies have been employed by the government depend on the position of the budget. If the government spends more than it receives through tax receipts then it will have a budget deficit. If it receives more than it spends then there will be a budget surplus.Two other terms that come about when talking about the budget are the following:

If the government spends more than it receives through tax receipts then it will have a budget deficit. If it receives more than it spends then there will be a budget surplus.Two other terms that come about when talking about the budget are the following:
- Public Sector Net Cash Requirement (or PSBR) - This is an account of how much the government has to borrow in order to balance the budget.
- Public Sector Debt Repayment (or PSDR) - This is when the budget is in surplus and the government can pay back some loans.
When using taxation as a fiscal policy, the government can change the rates of direct taxation or indirect taxation. Direct is tax paid straight from the income, wealth or profit of individuals or firms (income tax or corporation tax). Indirect is tax paid on goods and services (VAT or council tax).
The effects of fiscal policies are as follows, generally:
- A rise in taxes / a cut in government spending leads to a fall in aggregate demand.
- A cut in taxes / a rise in government spending leads to a rise in aggregate demand.
Now for the rules. "The Golden Rule" is a rule relating to the Labour parties thoughts that fiscal policy should be stable and consistent. This rule states that tax receipts should cover all government spending and that borrowing by the government should only be done for investment purposes. This rule applies over an economic cycle, not on an annual basis.
Another rule is the "Sustainable Rule". This states that government debt should be kept at a stale level. This means that debt shouldn't rise above 40% of GDP, this target is to be met every year.
Fiscal policy basics complete. Thanks.
