- Asap plz 15) International firms will invest in less developed countries at the beginning of their production life cycle, but as production is standardized and sold mainly on prices, they shift production to developed countries.Select one:O TrueO FalseHOTELLING MODEL Consider a market in which today’s crude oil price is $100/bbl, and the marginal cost of extracting another barrel of oil is $50. The interest rate is 10% per year. Assume that the market iscompetitive.a. What is the best prediction for the oil price 1, 2, 3, 4 and 5 years from now, based on the Hotelling model? Calculate the oil prices at the end of years 1, 2, 3, 4, and 5. The market suddenly learns that the marginal cost of extraction in years 2 and 3 will be only $40, after which the marginal cost is expected to fall to $20 for years 4 and 5.b. What is your prediction for future oil prices based on this new information? Calculate the oil prices at the end of years 1, 2, 3, 4, and 5. [Hint: assume that the price of year 1stays as in part a.]Consider the following Model (notation is standard):C=c(y-τ) I=i(r) y = C+I+G Md/P = L(y, r) Md= Ms=My = f(n) n = h(W/P) f´(n) = W/P Calculate the effects of a change in τ on C, I, r, y and P.

What happens to production in the long run ? (ii) A ruptured pipe in a North Sea oil rig produces a circular oil slick that is y meters thick at a distance x meters from the rupture.Turbulence makes it difficult to directly measure the thickness of the slick at the source (where x = 0),but for x > 0,it is found that y =0.5(x2 + 3x) /x3 + x2 + 4x.Assuming the oil slick is continuously distributed,how thick would you expect it to be at the source?Discuss the effects of COVID 19 Pandemic to financial markets and institutions in Malaysia.Consider the binary variable version of the fixed effects model with an additional regressor, D1; that is, let Yit = β0 + β1Xit + γ1D1i + γ2D2i +...+ γnDni + ui.a) Suppose that n = 3.
