Say in a market we haveDemand is P = 5 – 0.005QSupply is P = 0.00125Qa-you will have a graph with price on the vertical axis and quantity on the horizontal axis formost parts of this problem. You will want to show intercept values and equilibrium values withthe specific values from the problem (when you graph the supply show it go out at least to thesame level of Q as the Q intercept for the demand curve).b-what are the equilibrium price and quantity traded in the market?c-say the government levies an excise tax in the market of 50 cents that renders the supply tonow be P = .00125Q + 0.5 (essentially the supply curve shifts up by 50 cents at each quantity).What are the new equilibrium price and quantity traded in the market with this excise tax?d-did the market price increase by as much as the 50 cent tax? (compare the market priceincrease with the amount of the tax of 50 cents)e-what is then loss in consumer surplus from the tax? Do consumers like excise taxes?f-what is the elasticity…

The market demand for productXis given by: \[ Q_{d}=6-1 / 2 P \text { or } P d=12-2 Q \] The market supply for goodXis given by: \[ Q_{s}=-14+2 P \text { or } P s=7+1 / 2 Q \] whereP=price per unit andQis number of units. Draw a supply-and-demand graph with these curves. 1.) Using the line drawing tool, draw the supply and demand curves. Properly label your lines. 2.) Using the point drawing tool, plot the equilibrium point. Label your point 'E'. Note: Carefully follow the instructions above and only draw the required objects. The equilibrium price is$and the equilibrium quantity is unit(s). (Enter your responses as integers.) A per-unit excise tax is imposed on suppliers of productX, and the market supply with the tax is now given by: \[ Q_{s}=-19+2 P \text { or } P s=9.50+1 / 2 Q \] Using the graph on the right, show this supply curve. 1.) Using the line drawing tool, draw the new supply curve. Label your line 'S1+tax'.1. Note: Carefully follow the instructions above and only draw…

During the night, the electricity sector has a marginal cost of $1/MWh (megawatt-hour) forthe first 100 MWh produced (from wind turbines), and $20/MWh for each additional unit (from gasgenerators). During the day, they have a marginal cost of $1/MWh (megawatt-hour) for the first 50MWh produced (from solar panels), and $20/MWh for each additional unit (from gas generators).Nighttime and daytime demand are given by QnightD = 50 −P and QdayD = 200 −P , respectively.What are the market quantity and price during the day, and the market quantity and price at night?This is a model of the wholesale market for electricity, which you can think of as being competitive,but there is no resale between night and day.
indicate whether you think the statement is true or false andexplain why. 15. The discounted rate is usually positive.16. When constant marginal cost > 0, marginal net benefit (P-MC) increases at the rate ofinterest.17. Hotelling’s rule states that the dynamically efficient allocation occurs when the presentvalue of the marginal net benefit for the last unit produced is equal across time periods.18. Monopolist over-converse resources from a dynamic efficiency perspective.19. When the growth rate in demand exceeds the discount rate, the efficient outcome in acompetitive industry will result in a larger amount of oil available for the future period thanthe current period.20. Biofuels are a back-stop technology for oil and would cause more present production ofoil
