Chapter 5 – question 2, page 117
2. (Elasticity and Total Revenue) Explain the relationship between the price elasticity of demand and total revenue.
If demand is price inelastic, an increase in price will lead to increase in revenue because the percentage increase in price will cause a smaller decrease in quantity demand. If demand is elastic, an increase in price will lead to a decrease in revenue because the percentage increase in price will cause more reduction in quantity demanded.
Chapter 5 – question 5, page 118
5. (Determinants of Price Elasticity) Would the price elasticity of demand for electricity be more elastic over a shorter or a longer period of time?
It's inelastic in the short run and inelastic in the long run, but I guess it would more elastic in the long run than in the short run when people can find substitutes.

...MANAGERIAL ECONOMICS ASSIGNMENT 1A & 1B RUCHIKA SHINGNE 201600225 SEC C 1a. Scope of Economic Analysis Introduction Economics is the science of making decisions in the presence of scarce resources. Economics is the study of the production and consumption of goods and the transfer of wealth to produce and obtain those goods.

There are mainly two key ideas in economics; that goods are scares and society must use its resources efficiently. Managerial economics is the study of how to direct scares resources in the way that most efficiently achieves a managerial goal. Managerial economics is the application of microeconomic theory and methodology to decisionmaking problems faced by private, public and non-profit institutions. It assists decision-makers i.e. managers in efficiently allocating scarce resources, planning corporate strategy, and executing effective tactics. Managerial economics to a certain degree is prescriptive in nature as it suggests course of action to a managerial problem. Problems can be related to various departments in a firm like production, accounts, sales, etc. Managerial economics or economics is categorized in two types; microeconomics and macroeconomics.

Managerial Economics

...Managerial Economics is a branch of economics. With the help of this branch, we can apply Economics in decision making. Managerial Economics bridges the gap between economic principles/ theory and managerial practice. To take a specific decision, this branch applies micro economic analysis. We can apply the principles of Economics in taking decisions related to some problems like scale of operation, quantum of resources to be employed, marketing etc. Because of the scarcity of the resources it is not possible to have whatever we want. To get the better value from limited resources it is essential to evaluate the difference between the total cost and the total benefits of any activity. To choose the better option one of the tools provided by the managerial economics is marginal analysis. By weighing the marginal benefits against the marginal costs one can take the best decision. Marginal Costs- Marginal cost is the change in total cost when one more unit is produced. Marginal cost occurs when an activity increases by one unit. When the firm increases its production the total cost always increases even though the marginal costs may not rise. Rise in marginal costs is shown in the below chart. Following table shows the total cost and the marginal cost by making pizza: Quantity Total Cost Marginal Cost 0 0 -- 1 5 5 2 10 5 3 17 7 4 25 8 5 34 9 6 44 10 7 58 14 8 73 15 9 90 17 10 110 20 (MARGINAL ANALYSIS) Marginal Benefits- Marginal benefit is change in total benefit...

...Managerial Economics – Individual Assignment 1 ------------------------------------------------- Please answer all the following questions: All questions carry equal marks 1) - Managerial economics is the science of directing scarce resources to manage cost effectively. Explain how managerial economics concepts can help understanding strategic decisions. (Max 1000 words) Microeconomics is the study that helps make decisions of allocating resources, services and prices, while macroeconomics studies the field of behavioural economy in a wider range, such as entire industries or economies. Managerial economics helps improve the analytical skills through rational thinking, as well as solving problems; it uses both the economic theories of microeconomics as well as econometrics in order to make rational managerial decisions. It is those theoretical concepts that help understand and make strategic decisions, but in order to be able to apply them, it is crucial to collect data carefully and organize it well, to establish a strong basis for decision-making. On the other hand, it is also of high importance that any business sets their goals before analysing the data collected, as those goals will be at the heart of any formulation of managerial objectives. As a matter of fact, managerial economics aims for the best decision-making context, meaning to achieve those objectives in the most efficient way, using the minimum available resources and creating no waste.

...Managerial Economics Definition: Managerial economics is the science of directing scarce resources to manage cost effectively. It consists of three branches: competitive markets, market power, and imperfect markets. Competitive markets (a) Markets. i. a market consists of buyers and sellers that communicate with one another for voluntary exchange. It is not limited by physical structure. ii. in markets for consumer products, the buyers are households and sellers are businesses. iii. in markets for industrial products, both buyers and sellers are businesses. iv. in markets for human resources, buyers are businesses and sellers are households. v. Note: an industry is made up of businesses engaged in the production or delivery of the same or similar items. (b) Competitive markets. i. markets with many buyers and many sellers, where buyers provide the demand and sellers provide the supply, e.g., the silver market. ii. the demand-supply model - basic starting point of managerial economics, the model describes the systematic effect of changes in prices and other economic variables on buyers and sellers, and the interaction of these choices. (c) Non-competitive markets – a market in which market power exists. Market power (a) Market power - the ability of a buyer or seller to influence market conditions. A seller with market power will have the freedom to choose suppliers, set prices and influence demand. (b) Businesses with market power...

...Managerial Economics and Globalization 1. Some games of strategy are cooperative. One example is deciding which side of the road to drive on. It doesn’t matter which side it is as long as everyone chooses the same side. Otherwise, everyone may get hurt. a. Does either player have a dominant strategy? Explain. There is no dominant strategy from left or right. Both right and left could result in a higher payoff. b. Is there Nash equilibrium in this game? Explain. A Nash equilibrium exists when “players are in equilibrium if a change in strategies by any one of them would lead that player to earn less than if she remained with her current strategy (Shor, 2006).” Since neither player has a dominant strategy, this game does not have a Nash equilibrium. c. Why this game is called a cooperative game? Both players have to cooperate with one another and choose the same side. It is in the best interest of both left and right to choose the same side. If not, they will have a big negative payoff. 2. a. What is the firm’s Total Revenue? MC equals MR to maximize the profits. The monopoly output level is at E. From the demand curve, the price should be at A. Total revenue equals Price times Quantity. This is represented at area of AJEO\ b. What is the Total Cost? The average output E on the graph is H. The total Cost equals ATC times Q. This equals area BHEO. c. What is the firm’s Total Profits? Total profits equal total revenue minus total cost. This...

...Managerial Economics Chapters 1-6, 8 1) Goal Alignment at a Small Manufacturing Company The owners of a small manufacturing company have hired a manager to run the company with the expectation that he will buy the company after five years. Compensation of the new vice president is a flat salary plus 75% of first $150,000 of profit, and then 10% of profit over $150,000. Purchase price for the company is set as 4.5 times earnings (profit), computed as average annual profitability over the next five years. Does this contract align the incentives of the new vice president with the goals of the owners? A) No, these incentives are not aligned. If the VP keeps $112,500 of the first $150,000k then he will be motivated up to that point. Only 10% of the profit over $150,000 will be retained by him which is a very real decreasing marginal benefit. In addition, setting the purchase price based on profit certainly incentivizes him to keep the total profit down during that time. See below: So in this scenario he would earn $75k less over the 5 years, but would be able to buy the company for ½ the price. I have not factored in the flat salary as it isn’t really relevant except to add to the discrepancy even more. 2) Production Opportunity Cost A can manufacturing company produces and sells three different types of cans: versions X, Y, and Z. A high-level, simplified profit/loss statement for the company is provided here. Corporate overhead (rent, general and administrative...
