2. This presentation is about:
What is IndoTERM model?
Analysis of palm-oil land moratorium using IndoTERM model

3. A large system of non-linear equation solved by specialized software
IndoTERM
Each region is modeled as a separate economy, prices are different across regions.
Recursively run for every year toward 2030 through capital accumulation and other dynamic mechanism
Regions are connected through inter-regional trade of commodities and factors
is a dynamic inter-regional, bottom-up, computable general equilibrium (CGE) model of the Indonesian economy

A large system of non-linear equation solved by specialized software
Cover the whole national economy, generating standard macroeconomic variables

4. IndoTERM is a mathematical model which contains …
many equations (a system of non-linear equations with n equations, n endogenous variables, and many exogenous variables)
that determines prices and quantities
of commodities (many of them)
and inputs (including primary and intermediates)
characterized by
optimizing rational economic agents (e.g. producers and consumers)
who interact in a competitive market economy
such that all the markets are in equilibrium.

7. IndoTERM can be used for variety of purposes
Analyzing regional impact of national or international shock/policies
International oil price shocks
Import Tariff
Nation-wide indirect taxes
Analyzing nation-wide impact of region-specific shocks
Regional policies (regional taxes)
Regional specific productivity shocks (draught)
Analyzing impact of improving connectivity
Efficiency in transport services
Specific source-destination transport efficiency
Other areas

8. Research Questions
What is the implication of Indonesian Moratorium on Palm Oil Expansion from natural forest?
To what extent international transfer can mitigate its negative economic impact?

9. Scenarios and Assumptions
In the baseline, palm oil land grow by 3-8% per year toward 2030
½ of the land expansion come from natural forest, another ½ from production forest.
In scenario 1 (S1), expansion of palm oil land from natural forest is stopped in 2015 onward.
In scenario 2 (S2), expansion of palm oil land from natural forest is stopped in 2015 onward and Indonesia receives international transfers amount to $10x[CO2 emissions avoided]
Transfers is given directly to household in each region (in proportion to the region’s avoided emissions) to be spent on consumption.

10. Incorporating carbon emissions from land use change in IndoTERM
We estimate the carbon intensity per ha for each region and each land-using sector, including natural forest area
We added carbon emissions equation, and international transfers equation for avoided emissions.

11. Regional aggregation for this analysis
Western Sumatera: NAD, North Sumatera, West Sumatera, Bengkulu, Lampung
Northern Sulawesi: North Sulawesi, Gorontalo, South East Sulawesi
South Sulawesi: South Sulawesi, West Sulawesi, SulTra
Eastern Sumatera: Riau, Kepri, Jambi, South Sumatera, Babel
Bali
North Western Java: DKI, West Java, Banten
Nusa Tenggara: West Nusa Tenggara, East Nusa Tenggara
Eastern Java: Central Java, DIY, East Java
Maluku: Maluku, North Maluku
Western Kalimantan: West Kalimantan, Central Kalimantan
Papua: West Papua, Papua
Eastern Kalimantan: South Kalimantan, East Kalimantan

12. Palm Oil Production and Export of Edible Oil (S1, 2005=100)

Export of edible oil

13. GDP, Consumption, and GNE (% deviation from baseline)
Note: GDP = C + I + G + X – M
GNE = C + I + G

14. Household consumption by region in 2030 (% deviation from baseline)

15. Household consumption by provinces in 2030 (% deviation from baseline)

16. Highlights Impact on Indonesian GDP is negative but small
International transfers does not offset the impact on national GDP
Yet, international transfers (nationally) still make Indonesian on average better-off if consumption or national expenditure is a measure of welfare. This is the nature of international financing.
The effect varies widely across regions
Sumatera, and Western Kalimantan (West Kalimantan & Central Kalimantan) are the most heavily affected with moratorium without transfers.
Western Kalimantan benefit the most from international transfers.
International transfers does not offset the loss welfare of Sumatera.
Policy implication: Should there be any mechanism of equalization of the benefit of international transfers, if something like this happen?
