Consider historical data showing that the average annual rate of return on the s& p 500 portfolio over the past 85 years has averaged roughly 8% more than the treasury bill return and that the s& p 500 standard deviation has been about 21% per year. assume these values are representative of investors' expectations for future performance and that the current t-bill rate is 4%. calculate the utility levels of each portfolio for an investor with a = 2. assume the utility function is u = e(r) − 0.5 × aσ2. (do not round intermediate calculations. round your answers to 4 decimal places.)

Power plants that rely on coal increase the amount of sulfur dioxide that dissolves into the air, eventually increasing the acidity of precipitation. the higher acidity of rain and snow can damage forests by making it more difficult for plants to absorb minerals from the soil. the equations below provide information about the market demand and supply of electricity. there is a constant marginal external cost of $25 per unit of electricity. d: qd= 200 – 2ps: qs=p – 10what quantity of electricity satisfies allocative efficiency in this market? a. 60b. 70c. 50d. 43.3
