1Questions to Be PreparedLet us consider an open economy which has removed all barriers to capital mobility. The openeconomy comprises three agents: households, firms and a government (which includes monetaryauthorities). We denote GDP by Y, the domestic interest rate by r, the exchange rate (i.e., thepound sterling price of one euro) by e (a rise in e means a depreciation of the pound sterling), andby r* the world interest rate. Prices are fixed and normalized to unity. The economy is describedby the following equations:CC(Y-T), 0 0, NXy < 0,MDL (Y,r), Ly>0, Lr <0,MS =M + H₂CI = CI (r-r*), CI, > 0,(la)(1b)(1c)(1d)(le)(1f)(1g)(1h)where a bar indicates that the variable is exogenous; C and G are final consumption expenditureby households and the government, respectively, T are lump-sum taxes, I stands for invest-ment (i.e., gross fixed capital formation), NX net exports (i.e., exports, EX(e), less imports,e .IM*(e,Y), expressed in local currency, say pound sterling), MD and MS are money demandand supply; money supply MS = M + H includes an exogenous component, M, and an endoge-nous component H = ARES which is the change in international reserves; in a floating exchangerate regime, H = 0; CI are capital inflows defined as investment less savings; if CI > 0, it meansthat the country sells more domestic assets than it purchases foreign assets and thus experiencescapital inflows; if CI < 0, it means than the country purchases more foreign assets than it sellsdomestic assets and thus experiences capital outflows. A rise in r makes domestic assets profitableand thus leads to capital inflows.1. Which condition implies that an exchange rate depreciation produces an increase in netexports? Explain.12. Comment equations (1).3. Derive the slopes of the IS-, LM-, and BP-schedule in the (Y,r)-space. Develop intuitionabout their pattern. Note: for simplicity purposes, we assume that net exports is a goodapproximation of the current account.

Given information C=c(Y-T) I=Ir G=G T=T NX=nx(e,Y) Ml(r,Y) Ms=M+H CI=(r-r*)

Consider the following equations for a small open economy for both the goods and money markets.Goods Market: C = 3000 + 0.8Yd; T = 1000 + 0.3Y; G = 6000; TR = 500; I = 4000 + 0.24Y – 100r; M = 3000 + 0.2Y; X = 2000.Money market: LP = 1000 + 0.15Y; LT = 2000 + 0.25Y – 15r; Ls = 1000 – 35r; MS = 40,000; P= 4a. Derive both the IS and LM equations for the economy and compute the Equilibrium level of Income and Interest Rate.

Consider a developed country, Country A. Assume that the trade volume (exports + imports) with respect to its economic development level can be described by the following function: T(D)=2D^2+5D+9 Where: T(D) represents the trade volume in billions of dollars. D is the level of development, measured by some index (e.g., Human Development Index) where 0≤D≤10. Calculate the derivative of T(D) with respect to D. Interpret result in terms of the rate of change of trade volume with respect to development. At what level of development D does the country experience the highest rate of change in trade volume? If the standard deviation in the development index scores of developed countries is 1.2, how would this affect interpretation of trade patterns among developed countries? Note: For the purposes of this question, assume that the relationship is purely mathematical and doesn't account for other real-world factors that might influence trade volume.
