...A-LEVEL ECONOMICS ECON4/Unit 4: Mark scheme 2140 June 2014 Version 1.0 Final The National and International Economy Mark schemes are prepared by the Lead Assessment Writer and considered, together with the relevant questions, by a panel of subject teachers. This mark scheme includes any amendments made at the standardisation events which all associates participate in and is the scheme which was used by them in this examination. The standardisation process ensures that the mark scheme covers the students’ responses to questions and that every associate understands and applies it in the same correct way. As preparation for standardisation each associate analyses a number of students’ scripts: alternative answers not already covered by the mark scheme are discussed and legislated for. If, after the standardisation process, associates encounter unusual answers which have not been raised they are required to refer these to the Lead Assessment Writer. It must be stressed that a mark scheme is a working document, in many cases further developed and expanded on the basis of students’ reactions to a particular paper. Assumptions about future mark schemes on the basis of one year’s document should be avoided; whilst the guiding principles of assessment remain constant, details will change, depending on the content of a particular examination paper.

Macroeconomics Essay

...Running Head: Macroeconomics Jaque Mcilwain August 9, 2012 Morales Macroeconomics Class Thursday 6pm Abstract I will be discussing the two types of circular flow diagrams: One that represents the flows in the macro-economy as closed system and one that represents the flow as an open system. Circular Flow Diagrams. Circular flow diagrams are an economic model that illustrates the way a countries money flows or the way a country operates. There are two different kinds of flow charts and they are classified as an open system and a closed system. An open economy is basically a country that is completely reliant on and influenced by other countries and their economies. In other words most of their flow of money is based on what other countries are doing to generate income and operates off how the other countries money flow through the economy. A closed economy is self-reliant and is not influenced by what goes on in other countries or by what goes on outside of their economy. In other words this economy relies on itself when taking into account about the way money flows. An example of an open economy is really the world by default. If any nation trades with another country then they are known as an open economy by default. The United States and Great Britain are great examples of an open economy because they are highly dependent upon importation and exportation of goods and the industry. An example of a closed economy would be North Korea an enemy of the United States...

...the productivity gap; that we cannot put too much weight on any one factor but must see productivity as part of a wider picture; the extent to which productivity improvements are cancelled out by a rising rate of inflation and/or an appreciating exchange rate; productivity improvements become meaningless if we cannot sell any extra output in world markets for whatever reason, eg recession or poor quality.

Economics: Demand and Supply

...Pranav Vikram Shriram 1264456 Introduction to Economics BS1547 Introduction to Economics Macroeconomics Assignment- 1 Neo-Classical and Keynesian “The study of how society, and those in society allocate scarce and hence valuable resources between competing uses can be defined as Economics”(Jones, 2013) which was founded by Adam Smith in 1776. “The field of Economics that deals with the aggregate economy and changes in its level of unemployment, national income, growth rate, GDP, inflation and price level is called Macroeconomics.”(www.investopedia.com) As economics developed two distinct approaches were seen to immerge the Neo Classical which stated that Macroeconomics = ∑Microeconomics and the Keynesian which stated the opposite. Both these approaches are still followed in the managing of the present world Economies. Figure 1. As seen above, Neo classical approach lasted several years before the Great Depression, but was revived once again after the period of stagflation when the Keynesian approach failed to improve the economic condition. The Neo Classists approach influenced by Adam Smith and others with reference to the ‘invisible hand theory’ (Jones, 2013) stated that the “market is best left alone and that it will adjust and clear itself and hence finding its own macro-equilibrium.” (Jones, 2013) Keynes suggested that this is not realistic approach and that “government intervention is needed for the market to reach its macro-equilibrium.” (Jones, 2013) The Neo Classical...

The Great Depression Macro Paper

...It is hard to imagine that the sustained economic prosperity of the Roaring Twenties was soon followed by a severe worldwide economic depression. In 1929, the Great Depression began in the United States. By the time the economy hit rock bottom in 1933, real GDP plunged nearly 30%. Real per capita disposable income sank nearly 40%. More than 12 million people were thrown out of work; the unemployment rate soared from 3% in 1929 to 25% in 1933. Some 85,000 businesses failed. Hundreds of thousands of families lost their homes (Wheelock 2008). The money supply had fallen 35%, prices plummeted by about 33%, and more than one-third of banks in the United States were either closed or taken over by other banks (Parker 2010) . Milton Friedman and Anna Schwartz, in their 1963 book A Monetary History of the United States, 1867–1960, call this massive drop in the supply of money “The Great Contraction.” Monetarists, including Friedman, argue that the Great Depression was mainly caused by this monetary contraction, poor policy-making by the American Federal System, and continued crisis in the banking system. While there are many credited theories that provide an explanation for the Depression, this essay will focus on Monetarism and John Maynard Keynes’s argument for government stimulus in order to combat the economic downturn. Causes For The Great Depression In their book A Monetary History of the United States, 1867–1960, Friedman and Anna Schwartz stated that the Depression began with...

The housing sector for the country has shown a good growth and this rate cut would also help in the easing of unemployment. The consecutive steps have been taken by Reserve Bank keeping in mind the fact that a lower exchange rate is needed for a balanced growth of the Australian Economy. Cash rate graph (source: www.global-rates.com) The Australian economy has constantly been altering cash rates as their monetary policy in the earlier years as inflation was never a big concern for the economy. We can further understand how the altering of cash rates will influence macroeconomic aggregates: Aggregate Demand and Aggregate supply curve From the shown diagram we can see that the demand AD1 is intersecting the supply AS1 in a flat area of aggregate supply. This situation is mostly seen when there is an excess economic capacity in the economy and minimal inflationary pressure. However, in the scenario of stagnated aggregate demand growth, there are high chances the economy might face a recession with a rising level of unemployment. In this situation to increase the aggregate demand the reserve bank of an economy lowers the interest rate to shift the aggregate demand...

...study of macroeconomics and microeconomics provides the fundamental tools to assists business owners and finance managers in the decision making process. These tools also assist us in understanding how organizations and the economy operate as a whole. Many factors affect supply and demand. Price is the main factor that affects the supply and demand levels, this change can be reflected by a movement along the supply or demand curve. Factors that are not related to price, will shift the entire supply or demand curves. Before a firm decides to make changes in the price of their goods, it must determine the price elasticity of demand for that good. In this reflection paper, each team member will evaluate and discuss important economic concepts covered during week one. Discussions will also include any topics that members are having difficulty understanding. The portion I am having difficulty understanding is the production possibilities curve. I understand that in order to produce more of one item, you must give up some level of the production of another item. My problem is that I am not able to interpret all of the points in the production possibilities curve graph.

...Economic Assessment: Outcome 2 &3 [Pick the date] 1a).What is Gross Domestic Product? GDP stands for Gross Domestic Product. GDP is the monetary value of all goods and services produced in a country within a given time period. Any goods or services produced outside the specified country is not included the country’s GDP. GDP is usually used as an indicator of an economy’s health and it also measure a country’s standard of living. GDP is often calculated quarterly and yearly and is used as a comparison to the previous quarter or year. GDP is composed of overall consumption of the country, government spending, investments and net exports (exports – imports). The formula for calculating is GDP = C + I+ G + (X-M). b).Distinguish between real gross domestic product and nominal gross domestic product. Nominal Gross Domestic Product is a monetary measure of the value of finished goods and services produced for a period of time (quarterly or annually). Nominal GDP does take inflation into consideration. Real Gross Domestic Product calculates the value of economic productivity in a given year accustomed for changes in price. It takes into consideration inflation before giving results. Real GDP is very different from Nominal GDP. This is proven below: 1. Nominal GDP does take inflation or deflation into consideration in its calculation whereas Real GDP is obtained only after including the effect of inflation or deflation. 2. Nominal GDP is calculated at current...
