Our writers will create an original "Explain the meaning of aggregate supply (AS) and aggregate demand (AD) and explain what factors cause shifts in the curves." essay for you Create order Aggregate demand is the sum of all expenditure in the economy over a period of time. AD = C+I+G+(X-M) Where: C = consumption Spending I = Investment Spending G = Government Spending (X-M) = net export or balance of payments (exports minus inputs) The aggregate demand curve describes the aggregate demand (overall level of spending) at different price levels. Traditionally the y-axis displayed price but current thinking has replaced this with inflation. This is because an actual fall in prices is unlikely and that central banks prefer to target interests rates as opposed to money supply as a policy tool. On the x-axis is measured real GDP or Real National Income or Real Output. The AD curve is taken to slope down from left to right (fig 1) because a rise in the price level is assumed to be met by a rise in interest rates which will increase the cost of borrowing. Therefore consumption spending will fall, investment will fall and international competitiveness will decrease resulting in a fall in exports and a rise in imports (balance of payments decreases). Shifts in AD occur when changes in C, I, G, X and M occur as the result for example a change in interest rates. Factors that increase C, I, G, X and M result in a shift of the curve outwards (AD2) and vice a versa. Factors affecting C, I, G, X and M are in fig 2 C I G X + M Wages Incomes; short term and expected Interest rates Actual wealth and wealth perception Taxes Credit Expected rates of return Interest rates Perception of future size market and inflations rates Tax system Willingness to borrow Political climate UK competitiveness Interest rates Overseas markets World economy Fig 2: Aggregate supply is the capacity of the economy, the amount it will produce (or can produce) at a given price. It is a function of the costs of production, level of technology, labour skills, incentives to production, taxation, capital, productivity and the labour market. However economists disagree on the resulting shape of the curve having an obvious impact on the conclusions of any analysis. There are three main approaches. Keysian economists suggest the curve shown in fig 3. At Yf the economy is at full production it cannot; labour force/skills and resources are exhausted. At Y1 the economy is at under-capacity and there will be widespread unemployment, since a lower level of production requires a reduced volume of labour. As the economy moves from Y1 to Yf resource and skill shortages occur. Shifts in the curve result from changes in the production possibility frontier. For example new technology or an increase in the workforce as the result of immigration Classical economists divide AS into long and short term (fig 4). In the short-term wage rates and other input costs are fixed. However companies can only increase production by increasing costs. For example, although wage rate stays the same the payment of overtime results in a higher wage bill. Increases in input costs (e.g. an increase in the wage rate) result in a shift of the curve upwards and vice versa. In the long term AS is said to be perfectly inelastic (vertical line), as wages and input costs are likely to adjust to price increases there will be no under use of resources and markets will clear resulting in firms supplying at the maximum capacity of the economy regardless of the inflation rate. 3) The middle approach used for general analysis fig 5. This assumes that as production increases so do costs but that this function although undefined falls somewhere between the Keysian and classical approaches. b) Using AD/AS diagrams with discussion, illustrate the likely impact of a rise in interest rates on the growth of output and the level of prices in the UK. Normally an interest rate rise would occur as a result of a rise in prices. However if we raise interest rates at a given price this rise will still increase the cost of borrowing. This will in turn lead to a fall in consumption spending and investment, international competitiveness will decrease resulting in a fall in exports and a rise in imports (balance of payments decreases). The AD curve will therefore shift inwards AD2 (fig 6). The equilibrium point between AD and AS will therefore move to E2. Since an actual fall in prices is unlikely this will result in a lower inflation level P2 but at the cost of a decrease in output (national income) and an increase in unemployment since the lower output requires fewer units of labour. Since we have moved along the AS curve to the left output growth is also likely to be diminished Q2. Explain why unemployment and inflation are a problem for business. A rise in inflation will result in a rise in interest rates, which will reduce aggregate demand, see Qu a. Reduction in demand will decrease sales and therefore profits, if businesses do not adjust this may also lead to oversupply. In addition as interest rates increase the cost of borrowing, investment will therefore be reduced limited the business capacity for growth. Interest rate raises also harm competitiveness abroad and therefore will be damaging to export driven industries. If inflation rates rise this is likely to force companies to raise wages in the long run, which will squeeze profit margins. Unemployment has an affect on consumption, if fewer people are working then they have less money to spend, less consumption results in reduced profits. Unemployment also indicates an economy at under capacity and therefore not maximising production which in turn means an under exploitation of potential (assuming demand would keep pace) sales/profits. Unemployed people also devalue in terms of experience and skills the longer they are unemployed which is damaging in the long term to business human resources Assess how the UK government policy has tried to control unemployment and inflation rates in the past 10 years. Since the 1992 UK exit of the ERM UK government policy has concentrated on the creation of a stable environment for business the major target of which has been to keep inflation low. The government set a target of 2.5% inflation (retail price index measure) responsibility for meeting this target has fallen to the bank of Englands monetary policy committee (MPC) who has used the interest rate base rate to manipulate inflation. In 2004 the chancellor change the inflation target to within 1% point of 2% consumer price index. Inflation has remained low throughout this period. By focusing in inflation we would expect a negative effect on unemployment (Philips curve). The government used policy to promote job creation and improve education and skills in order to counteract this (new deal). Till the end of 2004 the UK saw 50 consecutive quarters of growth, in addition the UKs growth and comparative economic strength have meant good international competitiveness all of which have meant that although unemployment has varied it has remained below EU average. Q3. a) Distinguish between a free trade area and a customs union in relation to the process of further economic integration. Free trade area is a group of countries or states between which there are no tariff (direct tax or duties paid on goods entering) or non tariff (restrictions on quantity or entrance method, must all come through one port, or excessive bureaucracy) barriers. The difference between this and a custom union is that for its members a customs union offers a free trade area but to non members it offers a uniform customs policy (equal tariff and non-tariff barriers) regardless of which country of the union the external goods will be entering. Both mechanisms further economic interdependence by promoting trade, the more dependent a country is on another for its supply of goods or services the greater its dependence on that country and the reciprocation of this is therefore interdependence. However a customs union requires further economic integration because of the necessity to agree and implement the universe external tariff system. In addition the internal free trade area of a customs union positively biases trade between member states thus forming closer economic ties between the small numbers of member states. A customs union is also normally formed as a method of increasing economic political and social ties between member states (e.g. EU) whereas general free trade agreements are normally directed at simply increasing trade and growth (e.g. GATT, WTO). b) To what extent do the disadvantages of a customs union outweigh the benefits enjoyed by many firms in the member states? The level of benefits or disadvantage to firms entering a customs union is greatly dependent on their situation prior to joining. If the states none union tariff level was high and firms were inefficient then joining the union would have a larger negative effect due to increased competition both from within the union and from outside (given a comparatively lower external tariff) and will be at a competitive disadvantage. If however the state has a low tariff structure and the firms are efficient they will benefit from better access to internal markets and if external tariffs are comparatively higher may enjoy more protection. The focus of a firms trading is important. If a firm imports resources form within the customs union these will become cheaper, if it imports from external states and the union tariffs are comparatively higher then its imports will become more expensive. If a firm operates domestically it will face increased competition form member states but may be better prote cted if tariffs are comparatively higher from external firms. Exporting firms will benefit form greater access to internal markets but may suffer from reciprocating tariffs of none member states if the CU tariff is comparatively higher. If a firm is prior to joining a CU highly protected and inefficient or if most of its business is done external to the union it is likely to have a net disadvantage in joining especially if the common external tariff differs negatively (dependent on firm) from the pre-CU level.

————————————————- Effective Speaking Skills ————————————————- the basics for The Ice-breaker The icebreaker! (Aurora Australis) No not that one†¦ You’re first speech as a Toastmaster and, arguably, you’re most important. The icebreaker is the pretext for all speeches to follow and the one in which you’re good and bad speaking habits are identified. My talk tonight will include the Icebreakers; Purpose, structure and provide you with information on how to write and present your first speech as a toastmaster. We will write a custom essay sample on Effective Speaking Skills or any similar topic only for you Order Now It is important to note that in the fourth and final night of speech craft you will all be giving your own icebreakers. So firstly what is the purpose of the icebreaker? Quite simply the icebreaker is designed to give new participants an introduction to public speaking; to give the speaker a feel for presenting a topic in front of a captive audience. The icebreaker is also used to discover speaking skills that you already have and identify which areas of your abilities need development. The icebreakers structure is typical to that of most speeches having an introduction, body and conclusion. Now without revisiting the fifth grade let me summarize quickly the most important features of each component. The introduction is used to reveal the topic and maybe most importantly GRAB ATTENTION. Continuing with your speech from this point would be futile if the listener has no reason to actively follow your speech. Great attention grabbers are things such as asking rhetorical questions, making startling statements, using humor or narrative and arousing curiosity. While most toastmasters are just as good listeners as they are speakers it is a simple truth that, outside of these walls, unless you give someone a reason to listen to you; they won’t. The body of course is the crux of your talk and the reason you are standing in front of your peers. We will touch more on what the body of an icebreaker speech would normally include shortly. Finally the conclusion is used to summarize your speech and should always finish with impact. This can be achieved by closing with a quotation or narrative. The second and most unique component to the Icebreakers structure is its timing. The Icebreaker is a four to six minute speech and as you will notice on the timekeepers lights; the green light appears at four minutes, the amber at five and the red at six. So how do I write and present my icebreaker speech? The best way to begin your speaking experience is to talk about a familiar subject – yourself. It would be near impossible to condense your life into 5 minutes so you must narrow it by selecting some significant and interesting life events that will give your fellow toastmasters an introduction and brief insight into you as an individual. This might include your birthplace, education, family and/or future ambitions. You could speak of your recent travels to Asia and tell of some funny stories whilst there or you could simply give a brief chronological account of your life to this point highlighting the key parts. Select your visual aids carefully should you choose to use them. Be wary not to provide too much or too little information so as to confuse the viewer and listener. For instance; if I was suddenly giving a lesson on the special theory of relativity it’s simply a gross impracticality to provide all the information in a single slide expecting the listener to understand. Instead provide your visual be it a slide presentation or object with as much simplicity and symbolism as possible so as to maximize meaning whilst minimizing clutter.

The Stranger Essays (295 words) - Emotions, Absurdist Fiction

The Stranger Beatrice Guapo Period 4 May 1, 2000 What is love to Muersault My father once said, If you cannot love, then you cannot live. In the novel The Stranger by Albert Camus, Muersault, the main character would not be able to comprehend this statement, let alone agree. Love seems to have no importance to character Muersault. In the beginning of the novel Muersault mother passes away. Sunday was over, that Maman was buried now, that I was going back to work, really, nothing had changed. This is Muersault's thoughts two days after his mother's death. Usually when a person mother dies there is a long healing process that can last a life time, but in Muersault's case he shows no signs of loss or pain. He gives the impression that he did not love his mother, and feeling this way is okay. Muersault is involved with a young woman named Marie. One day Marie asks Muersault if he loves her, he tells her It didn't mean anything but that I didn't think so. When two people are involved, there is a mutual compassion and concern for each other's feeling. If one were to ask if the other loved them, and they did not, they would find a delicate and considerate manner to tell them how they felt. Muersault answer gives the impression that he had not given his and Marie's relationship any thought before that moment, love wasn't a meaningful enough issue to subject it to any thought. To Muersault the issue love does not deserve contemplation. His mother death and significant other love request were dealt with as though they were an everyday event. How can a person really know how to enjoy the virtues of life if they cannot see the importance of love. English Essays

Where to Place the Possessive Apostrophe in a Surname

Where to Place the Possessive Apostrophe in a Surname Where to Place the Possessive Apostrophe in a Surname Where to Place the Possessive Apostrophe in a Surname By Mark Nichol You see them all the time during rural drives and suburban errands alike, those olde-fashioned wooden shingles mounted on mailboxes or dangling from porches or fastened to walls: â€Å"The Smith’s† and the like- stark reminders that possessives still throw many people for a loop. Rules about possessives can be complicated, but this error is straightforward enough: Take away the apostrophe and the final s, and what do you have? â€Å"The Smith.† That’s obviously not right (unless the resident ostentatiously refers to himself as â€Å"The Smith† or employs hammer, tongs, and anvil to practice her livelihood). Who lives at this house? The Munsters. Whose residence is it, then? â€Å"The Munsters’† - or perhaps â€Å"The Munsters’ house.† (The additional s is pervasive in books and many other media, while its absence is typical in journalism in the old days of mechanical typesetting, that meant one less piece of type to position and other more casual or ephemeral kinds of publications. In the organic medium of wood, the simpler style can easily be forgiven.) And what if the surname already ends with an s? The rule is to append es to the name, so, the plural of Addams is Addamses. The sign should therefore read â€Å"The Addamses,† or â€Å"The Addamses’ house.† This construction is admittedly cumbersome, and there is a way to avoid it without giving a passing copy editor a case of the shingles: Label your abode â€Å"The Addams house† or inform visitors and passersby that â€Å"The Addams family lives here.† This wording is not as folksy, but it still manages a homey touch without adding sibilant syllables or pesky apostrophes. Admittedly, this ubiquitous error is as much the fault of the sign maker as it is that of the person who commissions the sign, but because it’s difficult to make amends by amending an error engraved in wood, you might want to remember, when you approach the artist’s workbench, the rule for the proper position for the possessive apostrophe.

The Difference Between a Commonwealth and a State

The Difference Between a Commonwealth and a State Have you ever wondered why some states have the word commonwealth in their name? Some people believe there is a distinction between states and states that are also commonwealths but this is a misconception. When used in reference to one of the fifty states there is no difference between a commonwealth and a state. There are four states which are officially known as commonwealths: Pennsylvania, Kentucky, Virginia, and Massachusetts. The word appears in their full state name and in documents like the state constitution. Some places, like Puerto Rico, are also referred to as a Commonwealth, where the term means a location that is voluntarily united with the U.S. Why Are Some States Commonwealths? To Locke, Hobbes, and other 17th-century writers, the term commonwealth meant an organized political community, what we today call a state. Officially Pennsylvania, Kentucky, Virginia, and Massachusetts are all commonwealths. This means that their full state names are actually The Commonwealth of Pennsylvania and so on. When Pennsylvania, Kentucky, Virginia, and Massachusetts became part of the United States, they merely took the old form of state in their title. Each of these states was also a former British Colony. After the Revolutionary War, having Commonwealth in the state name was a sign that the former colony was now ruled by a collection of its citizens. Vermont and Delaware both use the term commonwealth and state interchangeably in their constitutions. The Commonwealth of Virginia will also sometimes use the term State in an official capacity. This is why there is both a Virginia State University and a Virginia Commonwealth University. Much of the confusion surrounding the term commonwealth probably comes from the fact that a commonwealth has a different meaning when its not applied to a state. Today, Commonwealth also means a political unit having local autonomy but voluntarily united with the United States. While the US has many territories there are only two commonwealths;  Puerto Rico and the Northern Mariana Islands, a group of 22 islands in the Western Pacific ocean. Americans who travel between the continental U.S. and its commonwealths do not need a passport. However, if you have a layover that stops in any other nation, you will be asked for a passport even if you do not leave the airport. Differences Between Puerto Rico and the States While residents of Puerto Rico are  American citizens they have no voting representatives in Congress or the Senate. They are also not allowed to vote in the Presidential elections. While Puerto Ricans do not have to pay income tax they do pay many other taxes. Which means that, like the residents of Washington D.C., many Puerto Ricans feel they suffer from taxation without representation because while they do send representatives to both Houses, their reps cannot vote. Puerto Rico is also not eligible for federal budget money allocated to the States. There is much debate around whether  Puerto Rico should become a state or not.

The importance of Coaching within Raising Employee Perfomance Research Paper

The importance of Coaching within Raising Employee Perfomance - Research Paper Example When there individuals within an organization that need to enhance their skills for better operations, coaching thus is done on them to improve their delivery potential as well as make those individuals more productive to the organization (Charness, 2014,pg.87). Coaching therefore will target areas such as skills that need to be developed or strengthened; the lapses that exist in work; behavior and performance output of individuals. When these weak areas are recognized within an organization, the employees are taken through coaching by the managers or supervisors depending on the organizations policy (Charness, 2014, pg.35). A case study that reveals the benefits of coaching can be drawn from the UK rail industry where up to 13 coaches were tasked with the responsibility of increasing the skills of customer service for about 350 people in their organization (customer hosts). As a tool to improve employees output, coaching has had other numerous benefits to UK rail industry including: nurturing and improving an individual’s talent; setting expectations about the employee and making the organization managers accountable; engaging leaders in organization activities; professional satisfaction; boost of employee morale; and overall improvement of the organizational goals. This report therefore aims to discuss coaching explaining its purposes; benefits; and challenges. Additionally, the report will give a brief conclusion on the topic of study. Coaching can be defined as process that enables an individual to learn and develop skills from a direction and advice provided by a seasoned expert or professional (Crane, & Patrick, 2014, pg.89). Additionally, coaching can be understood as a process that involves directing, training as well as instructing an individual or a group of persons to develop certain skills necessary to achieve some goal. Directions can be given through motivational talks while trainings offered through seminars and

Is global climate change man-made Essay Example | Topics and Well Written Essays - 250 words

Is global climate change man-made - Essay Example This leads to the growing debate of today, is global warming man-made? Or is it just a cycle that the Earth goes through? Greenhouse gases affect the Earth’s climate by increasing the greenhouse effect, which is a natural phenomenon whereby water vapor, CO2, and other gases in the atmosphere allow sunlight to pass through, but then absorb much of the heat from the earth that otherwise would have escaped to outer space. Without the natural greenhouse effect, the mean temperature would be about minus 18Â °C, and the Earth would be uninhabitable Emitting greenhouse gases in large amounts increases the concentration of these gases in the atmosphere, which then increases the greenhouse effect so that more heat is trapped by the atmosphere. This can increase the temperature of the atmosphere and change the climate on Earth. Probably the most harmful contaminant that people are responsible for releasing into the atmosphere is carbon dioxide. The energy sector has been cited as being responsible for three fourths of the carbon dioxide emissions, one fifth of the methane emissions and a good portion of the nitrous oxide released into the earth’s atmosphere. Most of this comes from the burning of fossil fuels, although deforestation, land clearing, and other agricultural practices have all led to rises in pollution levels. Without some sort of agreement between countries, this could become the factor that tips the scales toward mankind as being the biggest cause of climate change. Many of the statements that are for climate change being a natural event are true. Global climate change is natural, but it is due to men selfishness, and the fact that we are so inconsiderate, that it is taking place at such an alarmingly rapid
