Ep = - 0.36, P = 4 -0.36 = 4/(4-a) -0.36 (4-a) = 4 0.36a = 5.4 a = 5.4/0.36 = 15 Consider the following production functions: ? Y = 10K1/2L1/2 ? Y = 2K + 3L a. Fixing labor employment (L) at 16 units, what is the marginal product of capital when capital employment is 25, 35, and 45 for each production function? Do these production functions exhibit diminishing returns to capital employment? Explain. b. Are labor and capital complements under these production functions? Explain. c. Do these production functions have the property of constant returns to scale? Explain. d. Is either production function a â€Å"Cobb-Douglas† function? Explain. ï‚ · n economics, the Cobb–Douglas functional form of production functions is widely used to represent†¦show more content†¦There is now doubt over whether constancy over time exists. History Paul Douglas explained that his first formulation of the Cobb–Douglas production function was developed in 1927; when seeking a functional form to relate estimates he had calculated for workers and capital, he spoke with mathematician and colleague Charles Cobb, who suggested a function of the form Y = bL^kC^{1-k}, previously used by Knut Wicksell. Estimating this using least squares, he obtained a result for the marginal productivity of capital k to 0.75—which was subsequently confirmed by the National Bureau of Economic Research to be 0.741. Later work in the 1940s prompted them to allow for the exponents on C and L to vary, resulting in estimates that subsequently proved to be very close to improved measure of productivity developed at that time.[1] A major criticism at the time was that estimates of the production function, although seemingly accurate, were based on such sparse data that it was hard to give them much credibility. Douglas remarked I must admit I was discouraged by this criticism and thought of giving up the effort, but there was something which told me I should hold on.[1] The breakthrough came in using US census data, which was cross-sectional andShow 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. Now as we dive deeper in to the field of economics we realized that there are two separate categories that the study of economics breaks off into. The first is macroeconomics, macroeconomics is the study of the whole picture when it comes to economics.

For instance, 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.

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). When ETS is implemented it reduces the pollution of the environment caused by different firms thus making it its main goalRead MoreEconomics1654 Words   |  7 Pagesï » ¿1. 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). Because of limited resources and unlimited demands, society needs to decide how much to produce and distribute these relatively scarce resources. The basic economic problem can be define as what to produce, how much to produce and for whom to produce.

It can be measured either in nominal terms which include inflation, or in real terms that are adjusted for inflation. It is mainly influenced by unemployment, inflation, technology levels, rate of investment, population growth rate, among other factors. These factors are used further to explain the differences in the varying level of output per capita
