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

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

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 = PBDPt , ! Domestic producers’ loss = PACPt , ! Government revenue gain = CDEF , ! Net deadweight loss = ACE + BDF

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

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

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),

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.

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 Ps = (1 + s)P Static Welfare Consequences , ! Domestic producers’ gain = PBDPs. , ! Domestic consumers’ loss = PACPs , ! Cost of government subsidy = CDFE , ! Net deadweight loss = ACE + BDF.

Dynamic Bene…ts , ! Allows producers to overcome credit market failures , ! Learning–by–doing / positive externalities , ! Allows producers to overcome …rst mover advantage Exchange Rate E¤ects , ! increase in demand for domestic currency (from foreign consumers) , ! domestic currency becomes overvalued , ! real export prices rise , ! hurts other exporters (primary and manufacturing)
