Trade Policy in Developing Countries "Economically, what is the di¤erence between restricting imports of iron to bene…t iron producers and restricting sanitary improvements to bene…t undertakers?" Henry George (1886) Fall 2010 Huw Lloyd-Ellis () Econ239 Fall 2010 1 / 24
Import Substitution Basic idea , ! erect barriers to foreign imports , ! satisfy demand with domestic (less e¢ciently–produced) substitutes , ! allow domestic producers to become more e¢cient , ! eventually remove the trade barriers Main policy tools: , ! Tari¤s , ! Quotas (often combined with tari¤ beyond quota) , ! Non–tari¤ barriers Huw Lloyd-Ellis () Econ239 Fall 2010 2 / 24
The Impact of Import Barriers (Small Open Economy) Implicit assumptions: , ! competitive markets , ! all the parties get equal weight in the welfare analysis ! world price, P � , is independent of domestic policy , Static Welfare Consequences ! Domestic consumers’ loss = P � BDP t , ! Domestic producers’ loss = P � ACP t , , ! Government revenue gain = CDEF , ! Net deadweight loss = ACE + BDF Huw Lloyd-Ellis () Econ239 Fall 2010 3 / 24

Potential Dynamic Bene…ts From protecting domestic “infant” industry “Learning–by–doing” e¤ects , ! cost reductions that can only be achieved through on–going production Spillovers to other industries , ! e.g. through e¤ects on public education system Increasing returns to scale , ! DC producers often have a …rst–mover advantage , ! LDC producers must achieve an e¢cient scale to compete Huw Lloyd-Ellis () Econ239 Fall 2010 10 / 24

Problems with the Import Substitution Strategy Protection may induce continued ine¢ciency , ! becoming competitive requires costly e¤ort and investment , ! incentives to incur costs depend on ultimate removal of trade barriers , ! BUT once protected, removal of barriers becomes di¢cult — why ? , ! domestic producers may have little incentive to invest ) ultimately depends on credibility of the government’s strategy Huw Lloyd-Ellis () Econ239 Fall 2010 14 / 24
Detrimental impact on primary exports due to exchange rate distortions , ! widespread IS reduces demand for foreign currency , ! domestic currency becomes overvalued , ! foreign prices of domestic exports rise and demand for them contracts , ! tends to hurt primary goods producing sectors (e.g. agriculture), Huw Lloyd-Ellis () Econ239 Fall 2010 15 / 24
The Move away from Import Substitution Many LDCs ran into severe debt crises in the 1980s crises were not caused by IS policies, but it made it di¢cult to react , ! overvalued currencies — di¢cult to obtain foreign currency via exports , ! mis–allocation of resources due to distorted internal prices Strongly in‡uenced structural adjustment programs imposed by creditors (e.g. IMF) , ! required the removal of trade barriers as a condition for new lending. Huw Lloyd-Ellis () Econ239 Fall 2010 16 / 24
Export Promotion Basic idea , ! provide preferential treatment to exporters of manufactured goods , ! once they are established, remove this aid Main policy tools used in export promotion are: , ! export subsidies , ! reduced import duties on material inputs , ! preferential credit access and terms of that credit.

The Impact of Export Subsidies E¤ective world price for producers increased to P s = ( 1 + s ) P � Static Welfare Consequences ! Domestic producers’ gain = P � BDP s . , ! Domestic consumers’ loss = P � ACP s , , ! Cost of government subsidy = CDFE , ! Net deadweight loss = ACE + BDF . Huw Lloyd-Ellis () Econ239 Fall 2010 18 / 24
