...File C5-207 July 2007 www.extension.iastate.edu/agdm Elasticity of Demand E lasticity of demand is an important variation on the concept of demand. Demand can be classified as elastic, inelastic or unitary. An elastic demand is one in which the change in quantity demanded due to a change in price is large. An inelastic demand is one in which the change in quantity demanded due to a change in price is small. The formula for computing elasticity of demand is: (Q1 – Q2) / (Q1 + Q2) (P1 – P2) / (P1 + P2) If the formula creates a number greater than 1, the demand is elastic. In other words, quantity changes faster than price. If the number is less than 1, demand is inelastic. In other words, quantity changes slower than price. If the number is equal to 1, elasticity of demand is unitary. In other words, quantity changes at the same rate as price. Close substitutes for a product affect the elasticity of demand. It another product can easily be substituted for your product, consumers will quickly switch to the other product if the price of your product rises or the price of the other product declines. For example, beef, pork and poultry are all meat products. The declining price of poultry in recent years has caused the consumption of poultry to increase, at the expense of beef and pork. So products with close substitutes tend to have elastic demand. Figure 1. Elastic demand Elastic Demand Elasticity of demand is illustrated in Figure 1. Note that a change in price...

...Supply, Demand and Equilibrium in Linear Equation The quantity demanded is the amount of a good that consumers want to buy at a given price, holding constant all other factors that influence purchases. The demand function shows the mathematical relationship between the quantity demanded , the price of the product, and other factors that influence purchases. A demand curve plots the demand function, again holding constant other factors. The quantity supplied is the amount of a good that firms want to sell at a given price, holding constant all other factors that influence firms’ supply decisions. The supply function shows the relationship between the quantity supplied, the price of the product, and other factors that influence the number of units supplied. An equilibrium exists if no market participant wants to change its behavior. In a market, equilibrium occurs at the price and quantity where the demand curve and the supply curve intersect. Example Problem: :SUPPLY AND DEMAND .AT $1.40 PER BUSHEL,THE DAILY SUPPLY FOR OATS IS 850 BUSHELS AND the daily demand is 850 bushels.when the price falls to $1.20 per bushel,the daily supply decreases to 350 bushels,and the daily demand increases to 980 bushels.assume that supply and demand equation are linear A-find the supply equation. B-find the demand equation. C-find the equilibrium price and quantity. Let x1 = 120 cents Let x2 = 140 cents For the supply equation: Let y1 = 350 Let y2 = 850 For the Demand equation:...

...curve and the budget line; (ii) a kink in an indifference curve; (iii) a “corner” where the consumer specializes in consuming just one good. Here is how you find a point of tangency if we are told the consumer’s utility function, the prices of both goods, and the consumer’s income. The budget line and an indifference curve are tangent at a point (x1 , x2 ) if they have the same slope at that point. Now the slope of an indifference curve at (x1 , x2 ) is the ratio −M U1 (x1 , x2 )/M U2 (x1 , x2 ). (This slope is also known as the marginal rate of substitution.) The slope of the budget line is −p1 /p2 . Therefore an indifference curve is tangent to the budget line at the point (x1 , x2 ) when M U1 (x1 , x2 )/M U2 (x1 , x2 ) = p1 /p2 . This gives us one equation in the two unknowns, x1 and x2 . If we hope to solve for the x’s, we need another equation. That other equation is the budget equation p1 x1 + p2 x2 = m. With these two equations you can solve for (x1 , x2 ).∗ Example: A consumer has the utility...

...1. Deadlock (“deadly embrace”) is a system-wide tangle of resource requests that begins when 2 or more jobs are put on hold. • Each job is waiting for a vital resource to become available. • Needed resources are held by other jobs also waiting to run but can’t because they’re waiting for other unavailable resources. • The jobs come to a standstill. • The deadlock is complete if remainder of system comes to a standstill as well. • The resources can be categorized into physical and logical resources. The physical resources are printer, disk drive, cpu, memory, scanner etc. The logical resources are files. • Deadlock is more serious than indefinite postponement or starvation because it affects more than one job. • Because resources are being tied up, the entire system (not just a few programs) is affected. • Requires outside intervention (e.g., operators or users terminate a job) to resolved the deadlock. 2. Seven Cases of Deadlocks Case 1 Deadlocks on file requests Case 2 Deadlocks in databases Case 3 Deadlocks in dedicated device allocation Case 4 Deadlocks in multiple device allocation Case 5 Deadlocks in spooling Case 7 Deadlocks in disk sharing Case 8 Deadlocks in a network Case 1: Deadlocks on File Requests | |If jobs can request and hold files for duration of their...

...Chapter 1 Microeconomics of Consumer Theory The two broad categories of decision-makers in an economy are consumers and firms. Each individual in each of these groups makes its decisions in order to achieve some goal – a consumer seeks to maximize some measure of satisfaction from his consumption decisions while a firm seeks to maximize its profits. We first consider the microeconomics of consumer theory and will later turn to a consideration of firms. The two theoretical tools of consumer theory are utility functions and budget constraints. Out of the interaction of a utility function and a budget constraint emerge the choices that a consumer makes. Utility Theory A utility function describes the level of “satisfaction” or “happiness” that a consumer obtains from consuming various goods. A utility function can have any number of arguments, each of which affects the consumer's overall satisfaction level. But it is only when we consider more than one argument can we consider the trade-offs that a consumer faces when making consumption decisions. The nature of these trade-offs can be illustrated with a utility function of two arguments, but is completely generalizable to the case of any arbitrary number of arguments.1 An advantage of considering the case of just two goods is that we can analyze it graphically because, recall, graphing a function of two arguments requires three dimensions, graphing a function of three arguments requires four dimensions, and, in general, graphing...

...ECONOMICS 247 ASSIGNMENT 1 VERSION B 1a. The study of economics is the study of how society manages its scarce resources. If however, this was no longer the case and scarcity disappeared, then the study of economics would cease to exist. There would be no point in tracking how society manages its resources if everyone can get exactly what they wanted. Opportunity cost would also cease to exist due to the fact that there would be no more scarcity. Opportunity cost is the cost of the choice that the consumer makes in terms of what the consumer must give up to get it. If everyone can get what they wanted due to the unlimited resources then consumers wouldn`t have to make choices. b. The difference between a “change in supply” and “a change in quantity supplied” is that one is a shift in the supply curve and the other is a movement along the supply curve. A change in supply is a shift in the supply curve and a change in quantity supplied is a movement along a fixed supply curve. 2a. Microeconomics studies “the impact of a change in consumer income on the purchase of luxury automobiles” b. Microeconomics studies “the effect of a change in the price of Coke on the purchase of Pepsi” c. Macroeconomics studies “the impact of a war in the Middle East on the rate of inflation in Canada” d. Macroeconomics studies “factors influencing the rate of economic growth” 3a. The determinant of supply that has an impact is change in technology. The cost of producing hot chocolate is reduced...

...Chapter 6: CPU Scheduling • • • Basic Concepts Scheduling Criteria Scheduling Algorithms Operating System Concepts 6.1 Basic Concepts • Maximum CPU utilization obtained with multiprogramming. • CPU–I/O Burst Cycle – Process execution consists of a cycle of CPU execution and I/O wait. – Example: Alternating Sequence of CPU And I/O Bursts – In an I/O – bound program would have many very short CPU bursts. – In a CPU – bound program would have a few very long CPU bursts. Operating System Concepts 6.2 1 CPU Scheduler • The CPU scheduler (short-term scheduler) selects from among the processes in memory that are ready to execute, and allocates the CPU to one of them. • A ready queue may be implemented as a FIFO queue, priority queue, a tree, or an unordered linked list. • CPU scheduling decisions may take place when a process: 1. Switches from running to waiting state (ex., I/O request). 2. Switches from running to ready state (ex., Interrupts occur). 3. Switches from waiting to ready state (ex., Completion of I/O). 4. Terminates. • Scheduling under 1 and 4 is nonpreemptive; otherwise is called preemptive. • Under nonpreemptive scheduling, once the CPU has been allocated to a process, the process keeps the CPU until it releases the CPU either by terminating or by switching to the waiting state. Operating System Concepts 6.3 Dispatcher • Dispatcher module gives control of the CPU to the process selected by the short-term scheduler;...
