- Under intervention A, the status quo, 15% of 3-year-old children in the country of Granada die from Dengue and under intervention B, a new intervention only 10% of children in Granada die from Dengue. The life expectancy at three years in Dengue is 55 years. The cost of intervention A is $100 and the cost of intervention B is $185. What is the incremental cost-effectiveness ratio (ICER) comparing intervention B to intervention A expressed as a. cost per life-years b. cost per life-years savedAt a raffle, 100 tickets are sold for 1 prize of $100 and 3 consolation prizes of$20. If the ticket is worth $2, what would be the expected value?Monthly sales of a particular personal computer are expected to decline at the following rate of S'(t) computers per month, where t is time in months and S(t) is the number of computers sold each month. S'(t)= -25t^(2/3) The company plans to stop manufacturing this computer when monthly sales reach 900 computers. If monthly sales now (t=0) are 2,100 computers, find S(t). How long will the company continue to manufacture this computer?
- The government of a subtropical country is evaluating the costs and benefits of protecting a rainforest versus cutting it down for timber. The estimated value of the wood is $270$270 million. If the same forest is used as a national park, it may attract 0.030.03 million additional tourists per year. Statistically, each tourist spends $1,600$1,600 inside the country during their stay.How long will it take tourism to exceed the estimated value of the wood in the rainforest? Enter your answer in the box below and round to two decimal places if necessary.Assume a firm located in a non-urban location pays a wage of $34/hour. However, it is assumed that there is a 20% chance that workers incur "switching costs" of $14/h. a) what is the expected wage? b) If a firm in an urban cluster wants to match the expected wage (and all else is equal), what should it pay assuming that urban switching cost is only $10 and the chance that switching is necessary is only 10%.Socioeconomic impacts of COVID-19 – can globalization prevail in the face of the impeding recession?As the COVID-19 crisis continues to deepen, the significant health and economic consequences of this disease is crippling even the most developed nations. With < 0.5% of globally confirmed cases occurring in Africa, the continent appears so far to be relatively spared the untoward direct health consequences of the COVID-19 pandemic. The disease nonetheless has already had a destabilizing effect on the lives of millions of Africans with disproportionate impact on the poor and underserved. The interconnectedness that characterizes globalization has brought economic benefits to many African countries. With COVID-19, there have been disruptions in Africa’s global supply chains in the face of tumbling oil prices and a lowered global demand for African non-oil products, which constitutes a threat to the economic stability of the continent. Projected losses from oil shocks alone may result…
- The economically destructive price spike of 2007–2008 occurred when spare production capacity fell below 1 mbpd, causing a run-up in oil price from $50 to $145 per barrel. An issue for world oil spare capacity is the internal consumption of OPEC producers. OPEC production has ranged between 30 and 33 mbpd since 2004. Internal use is currently about 25% of total OPEC production, but it is growing by 2% per year. The internal consumption growth is largely for nonelastic end uses such as electricity generation, water treatment, and new buildings. If the current world spare capacity is 2 mbpd and the OPEC total production does not increase beyond 33 mbpd, how many years will it take for the spare capacity to fall below 1 mbpd again?Out of 10000 people in a community, each is willing to pay Ksh 10 for each well dug.
