4. Suppose you are the manager of a restaurant that serves an average of 400 meals per day at an average price per meal of \$20. On the basis of a survey, you have determined that reducing the price of an average meal to \$18 would increase the quantity demanded to 450 per day. a. Compute the price elasticity of demand between these two points.
=0.125
b. Would you expect total revenues to rise or fall? Explain.
I would expect the total revenue to fall because it its less the price elasticity of demand is less than one, so that means that the demand is not sensitive to price change. c. Suppose you have reduced the average price of a meal to \$18 and are considering a further reduction to \$16. Another survey shows that the quantity demanded of meals will increase from 450 to 500 per day. Compute the price elasticity of demand between these two points.
=1
d. Would you expect total revenue to rise or fall as a result of this second price reduction? Explain.
It would not fall or rise because price elasticity is equal to one, making it not affecting the total revenue e. Compute total revenue at the three meal prices. Do these totals confirm your answers in (b) and (d) above?
The total revenue for 400 meals, at an average of \$20 per meal, is 8000
The total revenue for 450 meals, at an average of \$18 per meal, is 8100
The total revenue for 500 meals, at an average of \$16 per meal, is 8000
The totals don’t confirm my answers in b and d because the demand is sensitive to price...

Indeed the world is ruled by little else. Practical men, who believe themselves to be quite exempt from any intellectual influences, are usually the slaves of some defunct economist. John Maynard Keynes (1883-1946) Two fundamentals facts together constitute the economizing problem and provide a foundation for economics: Society’s economic wants and Economic resources. Individuals and institutions have innumerable unfilled wants and creating unstable economic conditions. Macroeconomic is concerned with the behavior of the economy as a whole; instead of focusing on the factors that influence the production of particular products and the behavior of individual industries, it focuses on the determinants of total national output. Macroeconomic is concerned with the decision. Decisions to achieve the economic goals, Sustainable economic......

...Project part I product | Estimated elasticity | Barnes & Noble books | -4.00 | Coca-Cola | -1.22 | Cigarettes | -0.25 | Beer | -0.23 | Gasoline | -0.06 | BARNES & NOBLE BOOKS Barnes & Noble Books are elastic. The price of elasticity is always negative. In comparing elasticities we are interested in their size. So we drop the minus sign and compare their absolute values. The estimated elasticity is 4.00 which are greater than the absolute value of 1.00 so this good is elastic. Since Barnes & Noble Books are elastic a proposed tax increase will have an increase in price which will reduce the total revenue. Because books are more money people buy less and the distributors share the tax burden which decreases their total revenue + a decrease in sales. Buyers will pay a larger portion of the tax because it does not matter whether the buyer or seller pays the tax. It is all relative either way they pay the same amount. Relative to the quantity being sold. COCA-COLA Coca-Cola is an elastic good. If demand is elastic then an increase in price due to an increase in taxes will reduce revenue for Coca-Cola. You will then have a decrease in quantity demanded also because this good is a substitute. Again as in Barnes & Noble Books buyers will pay more tax than the sellers will. CIGARETTES Cigarettes are inelastic because they are less than the absolute elasticity value of 1. Because cigarettes are inelastic an increase in price due to the tax......

...This work is licensed under a Creative Commons License - Attribution-NonCommercial 2.0 Germany Transaction Cost Economics: An Introduction Oliver E. Williamson This overview of transaction cost economics differs from prior overviews to which I have contributed in two respects: it presumes little previous knowledge of the transaction cost economics (hereafter TCE) literature; and it is organized around the “Carnegie Triple” – be disciplined; be interdisciplinary; have an active mind. It is partly autobiographical on that account.1 Section 1 discusses the Carnegie Triple and sets out five key quotations that anchor the transaction cost economics project. Sections 2 through 4 describe how TCE implements each element in the triple. Section 5 discusses operationalization. The conclusions follow in Section 6. 1. 1.1 Introduction The Carnegie Triple It was my privilege...

#### The Money Multiplier

...Money and Banks: Some Theory and Empirical Evidence for Germany Oliver Holtem¨ ller∗ o November 2002 Abstract This paper contributes to the analysis of the money supply process in Germany during the period of monetary targeting by the Bundesbank from 1975-1998. While the standard money multiplier approach assumes that the money stock is determined by the money multiplier and the monetary base it is argued here that both the money stock and the monetary base are determined endogenously by the optimizing behavior of commercial banks and private agents like households and ﬁrms. An industrial organization style model for the money creating sector that describes the money creation process is developed assuming that the main policy variable of the central bank is the money market interest rate. A vector error correction model for the nominal money stock, the monetary base, nominal income, short-term and long-term interest rates, and the required reserve rate is speciﬁed, and the interaction between these variables is analyzed empirically. The evidence contradicts the money multiplier approach and supports the presented model of the money creating sector. JEL Classiﬁcation: C32, E51, E52 Keywords: Industrial organization approach to banking theory, money multiplier, endogenous money, vector error correction model ∗ This paper is partially based upon the second chapter of the author’s doctoral dissertation (Vector au- toregressive analysis and monetary policy, Aachen:...

They come in all shapes and sizes, but have the following common characteristics: g g g g g g Owners. Managers. Objectives. A pool of resources (labour, physical capital, ¢nancial capital and learned skills and competences) to be allocated roles by managers. Administrative or organizational structures through which production is organized. Performance assessment by owners, managers and other stakeholders. Whatever its size, a ¢rm is owned by someone or some group of individuals or organizations. These are termed shareholders and they are able to determine the objectives and activities of the ¢rm. They also appoint the senior managers who will make day-to-day decisions. The owners bear the risks associated with operating the ¢rm and have the right to receive the residual income or pro¢ts. Where ownership rights are dispersed, control of the ¢rm may not lie with the shareholders but with senior managers.

#### How Economists Think

...ECONOMICS _____________________________________________________________________________________ WEEK 1: HOW ECONOMISTS THINK * What are preferences? Preferences refer to all of the objectives an individual wants to achieve that might motivate a choice among a set of alternatives. * What does it mean for an individual’s preferences to be rational? Please explain the concepts of costs and benefits and the reasoning process used by a rational individual. A rational individual will try to make the best possible use of his/her scarce resources, usually choosing an activity that has the highest utility. Rational preferences possess 2 properties, which are completeness and transitivity. Completeness means that choices can be ranked in an order of preference. For instance, an individual will have a preference when faced with two choices. Transitivity means actions can be compared with other actions. As an example, if action a is preferred to b, and action b is preferred to c, then a is preferred to c. A benefit is the maximum unit of currency amount you would be willing to pay to do x, while the cost is the value of all the resources you must give up in order to do x. The cost-benefit approach to decisions states that an individual should do an activity x if the benefit exceeds the cost. Relating to cost, in the process of coming up with a decision, a rational individual will take into account opportunity costs and ignore sunk costs. * New theories argue......

#### Modern Portfolio Theory (Mpt) and Financial Economics a Theory of Lesser Turf

...Andrey Artemenkov, The department of economic measurements, GYY artemenkov@rambler.ru Modern Portfolio theory (MPT) and Financial Economics: a theory of lesser turf?♣ “In this age, which believes that there is a short cut to everything, the greatest lesson to be learned is that the most difficult way is, in the long run the easiest.” Henry Miller “[These are colossal] disproportions that have accumulated over the last few years. This primarily concerns disproportions between the scale of financial operations and the fundamental value of assets, as well as those between the increased burden on international loans and the sources of their collateral. … In effect, our proposal implies that the audit, accounting and ratings system reform must be based on a reversion to the fundamental asset value concept. In other words, assessments of each individual business must be based on its ability to generate added value, rather than on subjective concepts. In our opinion, the economy of the future must become an economy of real values. How to achieve this is not so clear-cut. Let us think about it together.” From the Address of Vladimir Putin, Prime Minister of Russia, at the Davos Economic Forum (February, 2009) This Part analyzes the pre-analytical foundations and macro-economic impact of the Modern Portfolio Theory1 (MPT) tenets, on which much of the present Western investment theory and financial economics is erected. Our general inference is that while the former are......
