  1. Government, Foreign Trade and Foreign Exchange Rate Functions CHAPTER 7

  2. 1. Significance of Government Expenditure • Inevitable to ensure governments’ existence • Instrument of fiscal policy • Component of AD

  3. 2. Why Government? • To frame / execute / monitor law and order • To grant / protect property rights • To provide public goods & encourage merit goods • To check market failures • To promote economic growth and manage business cycles Thus, governments spend and tax

  4. 3. Government Vs. Public Sector >Government ? >Public Sector ? 2. Why Government? > Government Vs. Public Sector

  5. 4. Govt. Expenditure Components • Consumption of goods and services • Wages / salaries for government staff • Food / clothing / shelter for military and others • Office and facilities for government actitities • Investment spending • Infrastructure • Defence • Education / health / administration • Others • Transfer payments • Public debt interest & Pensions • Subsidies • Grants and aids – social security

  6. 5. Determinants of Govt. Expenditure • Some consensus on government activities • Political  Autonomous: Fiscal policy instruments

  7. 6. Govt. Revenue Components • Taxation • Central, state and local governments • Direct and indirect taxes • Progressive, proportional & regressive taxation • Tax – GDP ratio a measure of government size • Tax function T = t Y (7.1) • Laffer curve • - Fallacy of ceteris paribus

  8. 6. Govt. Revenue Components – contd. Figure 7.1 Laffer Curve

  9. 6. Govt. Revenue Components – contd. • Grants from donors: Autonomous • Profits of PSEs and fees on public services • Dis-investments in PSUs: Autonomous • Borrowings and money printing (debt): Autonomous

  10. 7. Consequences of Government • Re-distribution of income • Pareto law • Behaviour of consumers / investors • Taxes/subsidies • Injections = Leakages identity • Automatic stabilizers • Keynesianmultiplier

  11. 8. Foreign Sector: Significance • Measure of Globalization • Net exports a component of AD • Additional factor to promote growth • Additional tools of stabilization policy in terms of tariffs, quotas, exchange rate system and the exchange rate

  12. 9. Foreign Trade • What are exports and imports ? • Trade barriers and policy • Exports of goods and services at FOB • Imports of goods and services at CIF

  13. 9. Foreign Trade – contd. a. Why trade? • Broader consumption basket • Advantages of competition • Comparative advantage / specialization • Economies of scale • Consumers’ preferences => Not a zero sum game: “win-win” situation

  14. 9. Foreign Trade Sector – contd. b. Trade barriers / facilitators • No trade regulation (ban) • Quotas (quantitative restrictions) • Tariffs (dis-incentives to import) • Export promotions • Tariff better !! • Consumers & producers’ surpluses • * Government tax revenue

  16. 9. Foreign Trade Sector – contd. c. Trade policy / globalization • Inward / outward looking • Current / capital account convertibility • Push / pull factors • Contagion effect • Infant industry • Foreign exchange risk, if it is flexible

  17. 10. Income Identity & Saving - • Investment Gap * Income identity: Y = C + I + G + (X - Z) - (Ti - S) [Y + TP - C - Td ] + [Td + (Ti - S) – G - TP] - I = NX => Saving – investment gap: S - I = NX (7.2) Since, Net export = - net foreign investment I - S = Net foreign Investment = Net capital inflow

  18. BoP Balance: Current a/c surplus = capital a/c deficit Thus, NX + NIA + NTA = Net capital outflow (NIA = net factor income from abroad and NTA = net transfers from abroad) Is trade/current a/c deficit good / bad? Good: Consumption/ investment more, inflation low Bad: External debt more but if it is due to good investment, no problem If we ignore NIA and NTA, S – I = NKO = NX 11. Balance of Payments Identity

  19. 12. Determinants of Capital Flows • >NKI = f ( id – iw) (7.6) • f > 0 • Covered interest parity: • irupee - idollar = (F – S) / S (7.7) • Uncovered interest parity: • irupee - idollar = (E – S) / S (7.8)

  20. S = f ( Y ) I = F ( r ) NKO = Ө ( r ) Where f1> 0 F1< 0 Ө1 < 0 13. Determinants of S, I and NKO

  21. 14. Determinants of Trade (a) Exports • World income (+ve) • Relative price • Domestic price relative to world price(-ve) (Forex rate) • Trade barriers (-ve) , U ] (7.3) X = f [ Yw ,

  25. 15. Effects of Foreign Trade • Injections - leakages identity • Exchange rate as an additional • instrument • Investment multiplier • Slope of AD curve

  26. 16. Measures to Correct Trade Deficit • Devaluation • Price elasticities: Marshall-Lerner condition • External debt / over shooting theory • Reactions of trade partners / beggar thy neighbour • Pass through devaluation • J curve phenomenon / short and long run • Import substitution/ reciprocal trade • Protectionist policy: Tariff, quotas, bans • Capital a/c surplus / Selling forex reserves

  27. 17. Time Path of Devaluation effects Figure 7.4: The J - Curve

  28. 18. Foreign Exchange Rate System • Fixed exchange rate system • Hard peg: • Dollarisation • Currency union • Currency board • Peg to single / composite currency • Soft peg (Horizontal / crawling band) • Bretton Woods System

  29. 18. Foreign Exchange Rate System – contd. • Floating exchange rate system • Clean / pure / or free float: No imbalance in BOP • Dirty / or managed float: - Sterilization - Asymmetric - India since 1993

  30. 18. Foreign Exchange Rate System – contd. • Ideal system • International trilemma • Foreign exchange risk • Depends on • Relative Inflation rate • Trade / commodity concentration • Size / level of eco development • Degree of openness

  31. 19. Determinants of Foreign Exchange Rate • (a) Real exchange rate is determined by the demand & supply of currencies: BoP theory (i) Demand for dollars (= supply of rupees) = imports of goods & services + exports of capital (ii) Supply of dollars (= demand for rupees) = exports of goods & services + imports of capital

  32. 19. Determinants of Foreign Exchange Rate – contd. * While imports and exports of goods & services depend on the real exchange rate, those of capital depend on the real interest rate. * Accordingly, the D and S curves with respect to real exchange rate slopes downward and upward for goods and services, and shifts parallelly to right and left for capital movements, respectively. * In order to not to complicate the graph, D and S curves in Figure below are for combination of goods and services, and capital movements.

  34. 19. Determinants of Foreign Exchange Rate – contd. * At equilibrium, Demand for dollars = Supply of dollars Or,Zg+s + Xk = Xg+s + Zk Or, Xg+s - Zg+s = Xk - Zk (7.9) => NX = - NKI (7.10) *If managed float, RBI would intervene and affect D and S of dollars and there by real forex rate. * Role of forex reserves

  35. 19. Determinants of Foreign Exchange Rate – contd. (b) Given the real exchange rate (e), nominal rate (E) is given by E = e [Pw / Pd] *Note that while real forex rate denotes the relative price of goods and services, the nominal forex rate gives the relative price of currencies.

  38. 20. Four significant variables in international transactions • Relative inflation rate • Relative interest rate • Relative economic growth rate • Foreign exchange rate

  39. 21. International Financial Institutions • > International financial institutions • IBRD / World Bank • IMF • WTO • Evaluation of their roles

  40. 22. Conclusion • Significance of US dollar / Euro / Yen • Closed vs. open (small and large) economy: In a closed economy, real interest rate is determined by domestic S and I. In a small open economy, real i = world real i if capital flows freely, information is perfect, and bonds are homogeneous. Large economy is one which exerts influence on the world interest rate when capital is perfectly mobile. • Saving - investment correlation puzzle
