- ADVERSE SELECTIONSomet Health Insurance Company wants to sell a health insurance product for $700 permonth. There is no requirement for healthy people to have insurance coverage. Thecompany conducts a survey to see how different populations respond to the proposed cost.People with no illnesses and disabilities, generally the young and healthy, respond that theydo not spend $700 on healthcare in an entire year, and most feel they would not waste somuch money on premiums when the chance of needing surgery or expensive healthcaretreatments is so small. However, older, sicker people think that $700 per month is a greatdeal, as most of them spend far in excess of this amount on healthcare. It seems like agreat deal for them. What will happen to the costs of the health insurance if only the older, sicker peopleenroll?information refers to a market where one side (either the buyer or theseller, but usually the buyer) has less information than the other side of themarket. When there is asymmetric information in a market, markets are inefficientbecause the side with less information doesn't want to take the risk involved inbuying (or selling) the good or service.One method of solving this problem is through screening. Screening is a strategyone uses when they don't have information. A screen can be any indicator thatlets the screener know if the good or service is reliable and will meet thescreener's wants.Offer an example of when you used screening to solve a lack ofinformation. What kind of screen did you use?• Was the screen effective? Were you happy with the result?Alocal toy manufacturer is using a production line that runs 8 hours per day and produces a toy that requires a total of 7 tasks to be performed. The daily demand is 100 toysTimes of the tasks are 273, 2.01, 2.13, 2.0, 2.61, 2.71 and 2.95 minutes for A, B C, D, E , and Grespectively. However, due to the nature of the product there are precedence rules that must be observed. Such that Task A does not need any predecessors: task B requires task A to be completed. To start task Deach require task B to be completedTask must be completed prior to stating task E. Task F needs both task D and task E to be completed. Finally, task G can start only once task Fiscompleted.Given we apply the most remaining tasks rule for balancing the assembly line, with broken according to longest task time firstWhat will the estimated idle time in minutes for THIRD workstation?
- You need to answer the first few questions to answer the last. I split up because of number of questions I can ask at once but the question couldn't be answered otherwisePisa Pizza, a seller of frozen pizza, is considering introducting a healthier version of its pizza that will be low in cholesterol and contain no trans fats. The firm expects that sales of new pizza will be $20 million per year. While many of these sales will be to new customers, Pisa Pizza estimaes that 40% will come from customers who switch to the new, healthier pizzai nstead of buying the original version. a) Assume cusotmer will spend the same amount on either version. What level of incremental sales is associated with introducing the new pizza? b) Suppose that 50% of hte cusomters who will switch from Pisa Pizza's orignial pizza to its healthier pizza will switch to another brand if Pisa PIzza does not introduce a healthier pizza. What level of incremental sales is associated with introducing the new pizza in this case?A city in Metro Manila conducted a survey on selling a Modernized PUV. They have surveyed 2 questions to the 1000 Filipino jeepney drivers/operators. a.

Graphically represent two companies, one with high market power and one with low market power.The following week, Amaia's informatics faculty advisor gives her some advice. In all their years of teaching they claim to observe that working on 75 multiple choice questions boosts a student's test score by about the same amount as spending an hour reviewing lecture notes. For simplicity, assume students are able to review lecture notes at a constant pace during each hour spent studying. Given this information, in order to use her 4 hours of time spent studying to get the highest possible test score, how many hours should she have spent solving multiple choice problems, and how many hours should she have spent reviewing lecture notes? 0 hours working on problems, 4 hours reading 1 hour working on problems, 3 hours reading 2 hours working on problems, 2 hours reading 4 hours working on problems, 0 hours reading
