(a) Explain how allocative efficiency is related to the concepts of consumer surplus and producer surplus. Consumer surplus is defined as the highest price consumers are willing to pay for a good minus the price actually paid. As shown in the diagram‚ P1 is the highest price consumers are willing to pay for a good. Pe is the equilibrium price determined by the market. Any consumers are willing to pay price higher than Pe will end up paying Pe. This means they pay less than they expect‚ therefore

Calculating Efficiency. Efficiency (%) = Useful Energy Out x 100 Total Energy In Questions 1) A light bulb takes in 30J of energy per second. It transfers 3J as useful light energy and 27J as heat energy. Calculate the efficiency. 2) A kettle takes in 2000J of energy per second. It transfers 1500J as useful heat energy and 500J is wasted as sound energy. Calculate the efficiency of the kettle. Remember: In the exam they may not

Pareto efficiency‚ or Pareto optimality‚ is a central theory in economics with broad applications in game theory‚ engineering and the social sciences. Given a set of alternative allocations and a set of individuals‚ a movement from one alternative allocation to another that can make at least one individual better off‚ without making any other individual worse off is called a Pareto improvement or Pareto optimization. An allocation of resources is Pareto efficient or Pareto optimal when no further

Efficiency Ratios The efficiency ratio is an indicator of how well Johnson and Johnson (J&J) is run on an organizational wide basis. Efficiency ratios are also defined as asset turnover ratios (Finkler‚ Kovner & Jones‚ 2007). The asset turnover ratio measures how productive J&J is in managing all of its assets to generate Sales. This efficiency ratio is calculated by dividing sales by total assets by total revenue. For year 2010‚ J&J had an asset turnover of 0.6. Comparing J&J’s

Sessions 6‚ 7 & 8 Economic Efficiency y Consumer Surplus A buyer’s willingness to pay (WTP) for a good p y( ) g is the maximum amount the buyer will pay for that good good. WTP measures how much the buyer values the good. Example: 4 buyers’ WTP for an iPod name Anthony WTP $250 Chad 175 Flea 300 John 125 Consumer Surplus Q: If price of iPod is $200‚ who will buy an iPod‚ and what is quantity demanded? q y A: Anthony & Flea will buy

You can see that visually in the graph (it is below the line of efficiency) and in the chart as well. It is Pareto efficient because both parties stand to gain from an alternative- the union would gain ten points if they moved to low pension and management would gain one. c. As you can see‚

There are many data management issues that need to be considered when dealing with new data‚ transferring data‚ or just storing data for long periods of time. For instance‚ if a corporation or business needs to store data for long periods of time‚ they may have to come up with multiple ways of storing the data in the event one device or method fails. Also‚ all things eventually wear out in time. Therefore‚ servers‚ hard drives‚ databases and any other technological data storing equipment or methods
