If not, economy may develop export “growth poles” that do not spillover.,8,Problems in Trade and Development,LDC Export Instability,9,Export Instability,Export Instability: Export earnings of LDCs fluctuate more than export earnings of Developed Countries. Problem given high degree of

7、 openness of LDCs, so export variability leads to GNP variability which is undesirable. Causes of Export Instability: All reasons associated with fact that LDC exports more heavily concentrated in primary products than manufactures. Agriculture products have inelastic supply, fluctuations in demand

8、lead to large swings in export prices and revenues. Primary products are necessities or inputs with inelastic demand, supply changes lead to large swings in export prices and revenues. LDC export bundle has high degree of commodity concentration. Lack of export diversity exposes LDC income to indust

9、ry variations.,10,Causes of Export Instability,11,Several policies have been tried by LDCs to stabilize their export earnings. None has been very successful. International Commodity Agreements (ICAs) International Buffer Stock Agreements: If world price falls below set floor, international agency en

10、ters market and buys good until floor attained. If world price rises above set ceiling price, agency sells good. International Export Quota Agreements: Producer Cartel chooses target sale price, forecasts demand, sets quantity produced to achieve target price. Prodn quotas adjusted if demand fluctua

11、tes to keep target price. Compensatory Financing: If export earnings fall below some forecast level, international agency (IMF) extends short-term loan, repaid later,Policies to Stabilize Export Earnings,12,LDCs have been enthusiastic users of ICAs. Problems with ICAs in practice fall into two categ

12、ories. Are effective ICAs possible? Crucial for buffer stocks are levels of ceiling & floor prices . If this price range does not include LR free-market equilibrium world price then agreement will not be sustainable. Crucial for export quotas are ability to forecast demand and for agreement to contr

13、ol all exporters of the good. Are ICAs desirable? ICAs may reduce export earnings and welfare of producing countries. Crucial whether price changes due to variations in supply or demand. If price changes from demand shifts then ICAs can hurt nation. If price changes from supply shifts then ICAs can

14、help nation.,Problems with ICAs in Practice,13,Problems in Trade and Development,LR Decline in LDC Terms of Trade,14,LR Decline in LDC Terms of Trade,Alleged there is persistent tendency for LDCs terms of trade (TOT) to fall over time. Prebisch-Singer hypothesis from statistical studies in 1950s. In

15、ferences invalid due to measurement error in terms of trade (exports f.o.b./imports c.i.f.) and quality changes in manufactures. Recent evidence mixed, more primary product price declines. Reasons for Alleged LR Decline in LDC TOT Differing income elasticities of demand for primary versus manufactur

16、ed products. Unequal market power in product and factor markets, particularly oligopoly pricing in manufactures. Technical change has reduced demand growth for primary products. Multi-national corporations (MNCs) worsen through transfer pricing when LDCs have restrictions on repatriating profits.,15

17、,Policies to Stop LDCs Declining TOT,Export Diversification LDCs should diversify into manufactured exports to reduce volatility of export earnings based only on primary products. Difficult to do. Export Cartels Use monopoly power to increase export price of commodity. Requires no substitutes for go

18、od & no exporters cheat on cartel price. Also Need Demand inelastic, both in SR and LR. Import and Export Restrictions Generally require country to be “large” for significant effect on TOT. Economic Integration Projects LDCs may form free-trade areas or common markets among selves or with both LDCs

19、and Developed Countries Increase trade between, develop unified presence in world markets, facilitate transfer of technology and capital.,16,Inward vs. Outward Looking Strategies,Appropriate trade strategy for an LDC? Inward-Looking Strategy Emphasizes import-substitution, attempts to withdraw from

20、trade. May work if economies of scale in import substitutes or infant industry argument for potential exports. Outward-Looking Strategy Emphasizes increase international trade from comparative advantage. Focus is on efficient allocation of factors in prodn. May also involve export-promotion policies

21、. Empirical Results Economic performance of outward-oriented economies braodly superior to that of inward-oriented economies in terms of avg. growth in real GDP, per capita GDP, income distn but not inflation.,17,Problems in Trade and Development,Economic Dualism,18,Economic Dualism,Dual Economy Dev

22、eloping economy that is divided into two sectors with significantly different levels of development. Generally think of a modern (high wage, high value output per worker, capital-intensive) vs. a traditional sector. Reasons for Dualism Markets within the economy are working poorly, particularly fact

23、or markets. Wage differentials argument combined with high urban unemployment. Import-substitution trade policies can aggravate dualism. Capital-intensity of import-substituting industries lead to wage differential. Export-promoting trade policies can cause dualism if export sector disconnected from rest of domestic economy (growth pole).,
