Economics - 1000 Words

Assume a consumption function that takes on the following algebraic form: C = $100 + .8Y. Assume that Y = $1000 what is the level of consumption at this income level. C = $100 + .8($1000) = $100 + $800 = $900. 1. Using the above figure calculate the marginal propensity to consume between the aggregate income levels of $80 and $100. Also explain why this consumption function is linear. The marginal propensity to consume is equal to $15/$20 = .75. The consumption function is linear because the marginal propensity to consume is constant and therefore the slope is the same throughout all income levels. 2. Assume consumption is represented by the following: C = 400 + .75Y. Also assume that planned†¦show more content†¦Therefore, if people have more money then they are likely to purchase more goods - potentially ones from our country, thus exports will rise and the value of net exports will increase. If disposable income abroad is low then exports will fall and the value of net exports will fall. †¢ Disposable income at home. This refers to how much money people at home have available to spend on luxuries. The more money people have at home, the likelier they are to spend - which can result in a rise in imports. Rising imports will have a negative effect on net exports on the overall aggregate demand. Vice versa. †¢ Exchange rates. These play a large part in the value of net exports. A fall in a countries exchange rate will reduce the price of exports and raise the price of imports, thus exports should rise and imports fall - resulting in an increase in net exports. A rise in a countries exchange rate will raise the price of exports and make imports cheaper, therefore making exports fall and imports rise. The overall effect will be a fall in net exports. 8. Explain the accelerator theory. The accelerator effect is when an increase in national income results in a proportionately larger rise in investment Consider an industry where demand is rising at a strong pace. states that if there is a small change in the production output of consumer change, there will be a much greater change in the productionShow MoreRelatedEconomics And Economics On Economics Essay1142 Words   |  5 PagesWhen we talk about economics we must first defined the word. Economics is a social science that studies human behavior and how to allocate our limited (scares) resources, efficiently and effectively to meet our unlimited human wants.

For inst ance, if there was an unlimited amount of money for everyone, then everyone would have everything they had always wanted and would not have to work to get the money. Everyone would have billion dollar homes and the nicest cars in the world. Unfortunately, we do have a limited amount of money, so the economists find ways to get around that. There are two types of economicsRead MoreEconomics : Economics Of Business1361 Words   |  6 PagesHND Accounting Economics FINAL REPORT: The Economics of Business DUE DATE: 20 May 2015 Catherine Macintosh 11006620 For the attention of Sarah Sutherland Word count: 1,243 (Excluding Acknowledgements, Abstract/Executive Summary, Terms of Reference, References Appendices TABLE OF CONTENTS Page 1.0 Costs 3 1.1 Total costs 3 1.2 Average costs Read MoreEconomics1291 Words   |  6 Pageshis profit. Do you agree? Use a graph to illustrate your answer. The argument is incorrect. As the graph shows, a reduction in marginal cost will cause a monopolist to reduce his price. 2. Economist Harvey Leibenstein argued that the loss of economic efficiency in industries that are not perfectly competitive has been understated. He argued that when competition is weak, firms are under less pressure to adopt the best techniques or to hold down their costs. He referred to this effect as x-inefficiencyRead MoreEconomics1444 Words   |  6 Pagesresource is inefficient it means the resources are not used in the best distribution by firms or organizations. An ETS is executed when the environment has been polluted and the government intervenes in order to control the pollution by providing economic encouragements towards the firms and organizations to reduce the amount of pollution emitted in the environment (Brown* 2001).

What is the ‘economic problem’? The fundamental economic problem is related to the issue of scarcity. Scarcity means that resources are limited and short in supply in the world (e.g. diamond).
