Growth and policy experiments
Growth: What happens when the labor force grows? When either sector’s capital stock expands?
Related questions: Productivity improvement: What happens when
producers adopt new, improved technologies?Policies: What happens when integration with world
market is conditioned, e.g. by a tariff?Effects on production, resource allocation, aggregate
income, income distribution?

Specific Factor Growth (FDI) and PPF
SE Asia: growth & dev. in open economies
Thailand’s trade and FDI-driven economic boom
Indonesia’s oil wealth and “Dutch Disease”

Manufactured exports - developing countries
Which countries industrialize, and why?Endowments: cheap labor, infrastructure,
resource-scarce (?)Relatively stable macroeconomic & political
conditionsLower barriers to investment and importation of
inputsEarly industrializers: Japan, Taiwan, Korea…
Size of domestic market prohibited closed-economy growth export orientation
Capital raised from domestic savingsLater industrializers: Thailand, Malaysia, VN
Same export orientation, but using foreign capital

Thailand: growth & poverty decline
In Thailand, growth was really fast in 1985-97
During this decade, trade/GDP rose and so did FDI/GDP, especially from E. Asia
Poverty also declined very fast Inequality did not increase much
Can we use SFM to understand these trends?
14
15
What factors contribute to poverty decline?
1. Overall economic growth
2. Direct anti-poverty policies
3. Indirect effects of international integration Job creation, esp. low-skilled labor Internal migration
Wage effects Remittances
16
Thailand: direct anti-poverty policies
Policies addressing opportunity, security, and community Opportunity: increasing labor productivity
through education and trainingSecurity: stabilizing incomes against shocks
(e.g. economic recessions)Community: building local capacity for
economic development and protection for poorThese direct policies had only mixed success
17
Indirect policies: globalization as anti-poverty measure
Globalization after about 1984:FDI inflowsTrade liberalizationOther pro-trade measures
Job creation through FDI and specialization in L-intensive tradables sectorsChange in structure of exports and employment: gr
of L-intensive mfgTransmission of gains: wage growth in non-ag and
in ag/rural areasThese structural changes associated with
globalization appear to account for the largest share of poverty alleviation progress in Thailand

Economy-wide spread of wage growth
Conclusions: Thailand Labor-intensive growth, e.g. of
manufacturing, has direct and immediate effects on poverty
FDI was mostly efficiency-seeking: E. Asian manufacturers looking for cheap labor
FDI increased stock of manufacturing sector capital
This raised total labor demand and encouraged rural-urban migration (spread of gains)
With prices mostly stable, real wages increased steadily through early 1990s

Resource Curse: Overview(http://en.wikipedia.org/wiki/Resource_c
urse)
Countries with rich natural resource bases have worse growth and development outcomes. Why?
One reason: “Dutch Disease”:1960s: Oil/gas discoveries by HollandHuge export “boom” from oil/gas sales, but…Severe domestic inflationLoss of manufacturing jobs and investmentSame phenomenon seen in other oil-rich countriesAre these changes all linked?
Specific factors model: increase in natural resource capital… effects on economy?
23
Nontraded goods and “real exchange rate”
SFM can explain structural change but not inflation
Need a 3rd sector – nontraded goods, with prices endogenous
Examples of NT goods; characteristics of marketsGoods may be non-traded (or effectively so) for intrinsic
reasons, or because of policy interventions D=S in domestic market; price must adjust to clear market
Demand for NT goods is usually elastic w.r.t. income growthTherefore, rise in income means rise in pN/pX and pN/pM
Why do we care?

The ‘real’ exchange rate
Real exchange rate = price of N goods in terms of all T goods (= pN/pT)RER is endogenous, even if prices of all T
goods set in world mkts (‘small country assumption’)
It conveys effects of changes in one sector, or in aggregate income, to other sectors Directly, through relative price changes Indirectly, through changes in factor prices
RER rise: indicator of inflation relative to other countries --> changes in relative production costs

(yT, yN) = (cT, cN)
RER = -pN/pT

Note: All tradable goods in one index, on vertical axis27
2. Resource wealth
Many dev. econs have relatively large resource sectors (minerals, agric., forestry) producing commodities for export to world mkts
These sectors & their global markets have special characteristics-- incl. volatility
What happens to the structure and performance of the economy when a resource sector experiences a “boom” (price rise, new reserve discovery, tech change)?
What are the contradictions/risks of rapidly rising income from a single booming sector?
2828
What do you think?
‘Income effect’: new income raises spending across the boardRise in N prices: domestic inflation, wage rises
Loss in profitability and jobs in T goods other than the ‘booming’ sector
Boom in gov’t revenues and spendingG. consumption or investment?
What about changes in factor returns?Labor, ‘capital’ in booming sector, etc.income distribution?
2929
Dutch Disease
Could a natural resource boom lead to “deindustrialization” (or “deagriculturalization”)?Why would a country like Venezuela export
only oil products and import basic goods like eggs?
Why did Nigeria’s export agriculture sectors collapse in the 1980s, and what were the consequences for incomes, welfare and poverty?
Why is Indonesia’s manufacturing sector now failing to grow?

3. Resource Boom Model
3 Sectors:1. Resource sector (oil, natural gas) - X2. Tradable (Ag, Manuf) – M3. All tradables together: T, so LT = LM + LX
4. Non-tradable (services, land) - NTExample (NT): Haircuts, restaurants,
health, educ.
Small open economy, one mobile factor – laborX production uses a specific factor (oil reserves,
mineral reserves), M and N both use specific capital.

Implications of Dutch Disease
Increased Dependence on Boom and Non-Tradable (NT) SectorsIncreased vulnerability to price shocksWorld commodity markets are very volatileNT sector adjusts through prices more than quantitiesHigher risks of macro instability
Rising NT prices means inflation and speculation (property booms, unproductive investments)
Decline of tradable sector Loss of comparative advantage is traditional industries
(Nigeria palm oil)May reduce potential for dynamic growth in manuf
industries35
Resource Curse:Lack of Diversification
Basic logic of why?Dutch Disease model explainsExpectations of easy wealthIncentives for entrepreneurs and innovators
shifted to wealth-grabbingEvidence of lack of diversification (boom sectors
dominating exports, Boom and non-tradables sector
dominating GDP)
36
Empirical Evidence on Lack of Diversification
Nigeria Petroleum, 95% exports, 20%
GDP, once a food exporter now importer,
70% labor in agriculture, 17% of GDP.
Ecuador Petroleum, 56% of exports,
Bananas 12% Oil-mining, 24% of GDP Ag 6% GDP, 8% of labor Services 60% of GDP, 68% of
LaborIran
Petroleum, 80% of exports, Ag 11% of GDP 30% of labor Unemployment 20% 37
Resource Curse: Rent-Seeking Behavior
Huge incentives to capture the “rents” (excess profits of resources). Foreign exploitation potential is high. Ex: $80/bbl of oil versus $8/bbl prod costs. Rents = Super-normal profits
Political economy of country dominated by efforts to control & capture rents.
Crowds out other kinds of political and economic initiatives.
Conflict becomes central (as does potential for dictators or authoritarian regimes).
38
Resource Curse:Feeble Taxation Systems
State control of resources (nationalization or taxation) reduces need for development of other tax systems. Oil-rich countries get almost all of their government
revenues from state oil company or taxes.Lack of public commitment to taxation system makes
government vulnerable to volatile prices of oil or other leading resource.
Also undercuts commitment to public expenditures. Low investment in public education common in resource
rich countries (competitiveness of workers lower priority when resource rents are main source of wealth).
Low commitment to democracy as well if public sector not viewed as carrying out allocation of people’s tax revenues.
39
Resource Riches Not Always a Curse
Empirical examples U.S., Canada, Australia Chile (copper, fruits, lumber) Norway and Sweden Botswana Malaysia Brazil Vietnam?
Why? Types of resource riches (ag/ind. Links) Types of institutions in place Size of economy/diversity of production sectors Timing of booms Policy choices
40
Summing up
Growth and globalization have a complex relationship
Understanding these requires careful analysisSimple models – heuristic devices (road maps)
Heckscher-Ohlin – ‘benchmark’ modelSFM: Extends H-O to take account of realities
(natural resources, limited adjustment capacity)Dutch Disease model: introduces macroeconomic
dimension with endogenous prices and many more development/political economy stories
