The question deals with market graphs, supply/demand, externalities, taxes, subsidiaries, and quotas.Part (a), we use the supply and demand equations, graph them, and see how much consumer and producer surpluses are there {triangle equation: bh(1/2)} using Qs, Qd, Pp, Pc, and the equations.Part (b,i) use previous CS and PS to get Total Surplus (TS).Part (b,ii) you draw market equlibrium Supply/Demand Graph and Graph Comp. And SO Supply. Indicate Equ. Price and quanity for both Equilibriums.Part (b, iii) indicate SO Equ. again and see if positve or negative externalities exist. I need help solving (b, iii).Part (b, iv) Get TS at SO Equ. with original Demand and SO Supply.Part (b, v) should econland widget industry shut down, need some guidance on this one.Part (c, i) new scenario, tax of 1.50 imposed, so the demand curve is steeper. Bigger CS and lower PS. Calculate CS, PS and GS and add them together.Part (c, ii), who bears more tax burden. Use PS ad CS with and without tax to see who had the greatest depreciation of surplus.Part (c, iii), use CS, and PS with tax, and the add GS to that to get TS.Part (d), I need help setting price ceiling and also calculating PS, CS, GS, and TS after that.Part (e) Same setting help needed for rpice floor and calculating TSPart (f) What are quotas? How can I use them to get SO Equ.? How do you calculate PS, CS, GS, and TS after that?And this is all assuming goverment gets to keep the quota.Please answer my questions embeded in the assumptions I wrote. Please provide clear, well-thought out, accurate answers. Please correct any of the assumptions I made if you think it’s wrong. Thank you for your guidance and pateince with reading and answering my quiery.
