Article history:
Received : 14 November 2019 Accepted : 10 January 2020 Published : 8 April 2020 Introduction Since early 1980s.
Indonesia has implemented internal measures to reform trade liberalization policies focusing on simplifying port and customs procedures, reducing import duty rates and other additional costs, simplifying import licenses and other non-tariff barriers, de-regulating import and distribution systems, de-regulating investment regimes, developing bonded zones and processing export shipments (Anas & Roesad, 2003.
Erwidodo, 1.
The main objective of the measures was improving the international competitiveness of domestic commodities.
In supporting the outward-oriented economic policy strategy, the Indonesian government carried out some external measures, including participating actively in bilateral, regional and multilateral trade cooperation.
Joining the cooperation schemes.
Indonesia must comply with agreements emphasizing trade liberalization.
The relationship between trade liberalization and economic in developing country has been an intensive controversial debate.
The integration of developing countries into the global economy has strengthened negative sentiments especially in the developing world that "the poor have become poorer and the rich have become richer.
" Many attributed this development to adverse effects of trade liberalization and globalization on the global economy in terms of increased poverty and income This negative sentiment was not totally baseless.
Some empirical studies have supported it, suggesting negative effects of trade liberalization on the poor population based on partial balance analysis (Ravallion.

or general equilibrium analysis (Lofgren, 2.
In contrast, the pro-view on trade liberalization emphasizes the importance of trade openness to improve economic growth.

International Monetary Fund (IMF) and the World Trade Organization (WTO), believe that trade liberalization will accelerate growth and reduce poverty in developing countries.
So far, only few studies have examined the relationship between liberalization and trade facilitation on the one hand and economic performance, poverty, and income distribution, on the other, that employed the computable general equilibrium (CGE) with the transmission that runs from macro level to micro level, in the context of Indonesia.
Therefore, this study aims at filling in this gap.
In doing so this study utilizes a more comprehensive computable general equilibrium (CGE) framework with a top-down model and relies on Indonesian data.
Methods The analysis in this study applied a computable general equilibrium approach with a top-down model, following the model developed in Decaluwe.

Maisonnave, and Robichaud .
This model is a static model of a country where companies are assumed to operate in a perfectly competitive environment.
Some changes were introduced to answer the research questions, including exogenizing trade transport costs, improved elasticity data from Indonesian case studies, and adjustment of closure in the model.
The top-down model was intended to relate macro data transmission .

to obtain new real expenditure data of individual households (Statistics Indonesia, 2008.
The poverty and income distribution inequality were measured based on both initial and new real expenditure data of individual households.
Poverty was analyzed using the Foster-Greer-Thorbecke (FGT) approach, and income distribution was analyzed using the Gini coefficient.
Data Sources The main data used in this study came from the 2008 Social Accounting Matrix (SAM) and the 2008 National Socio-Economic Survey (SUSENAS) (Statistics Indonesia, 2008a, 2008.
The supporting data included: Input-Output Table of 175 sectors in 2005.
Input-Output Table of 66 sectors in 2008 and a survey on Special Savings and Household Investments (SKTIR) in 2008 obtained from the publication of the Indonesian Central Bureau of Statistics, as well as the parameter data of estimated equation system obtained from previous studies deemed relevant (Statistics Indonesia, 2008d, 2008.
Although some sectors and households were the focus of the research, they were not included in the SAM 105 in 2008 published by the Central Bureau of Statistics (BPS).
The disaggregation was done for the production sectors, domestic commodities, and import commodities, respectively, from 24 sectors to 46 sectors.
Households were disaggregated from 8 household groups to 20 groups.

The Gini index value ranges between 0 and 1.
The higher the Gini index value, the greater the income inequality.
A Gini index value of zero implies a perfect evenness in the income distribution, whereas a value of one signifies perfect income inequality.

Scenario 5 The simulations in the agricultural sector in this study included the subsectors of soybeans, corn, vegetables, fruits, rubber, coconut, palm oil, coffee, cocoa, other crops, livestock and derived products, forestry and labor, shrimp and other fisheries.
Meanwhile, the simulations in the agricultural industry sector included simulations in the oil and fat industry, rice milling industry, all types of flour industry, sugar industry, beverage industry, other food industry, leather and leather products industry, wood industry and wood products, and rubber goods industry.
Results and Discussion The discussions on the results of the research simulations are grouped into three main topics: .
Impacts of trade policies on economic performance.
Impacts of trade policies on poverty.
Impacts of trade policies on income distribution.
The Impacts of Trade Policies on Economic Performance Import duty reduction Changes in economic performance as reflected in changes in macroeconomic variables due to the policy of reducing import duties on agricultural and agricultural industry sector are presented in Table 2.

Table 2 reveals that reducing import duty by 50% in agricultural and the agricultural industry increased the real GDP by 0.

in the domestic economy, led to a constantly high total supply of composite commodities in the domestic economy.
This condition encouraged the creation of more activities in the domestic economy so that the real GDP continued to increase.
This finding was in line with that of Dollar and Kraay .
, suggesting that trade openness increases economic performance.
Trade openness had significant positive effects on economic growth in Tanzania (Hamad.
Mtengwa, & Babiker, 2.
it also made significant positive effects on economic growth in Switzerland (Khobai & Chitauro, 2.
The growth was due to the efficiency gained through competition and productivity escalation.
The increase in the real GDP, as the result of import duty reduction policy in the agricultural sector, was significantly higher than that in the agricultural industry sector.
Tariffs reduction in the agricultural sector decreased the price of imported agricultural commodities.
This condition lowers the input costs for the agricultural industry, encouraging the output increment of the agricultural industry sector.
This result means that both import outputs of agricultural and agricultural industry sector are expanding due to the tariff reduction policy in agricultural sector, consequently increasing the real GDP.
Table 2 exhibits that the import duty reduction policy in agricultural sector and the agricultural industry sector increased the consumption by 0.
033% and 0.
095%, respectively The increase in consumption was thought to be a consequence of three factors: .
the decrease in composite commodity price.
the income increase of households and corporates.
the increase availability of composite commodities in the domestic economy.
The consumption increment due to the import duty reduction policy in the agricultural sector was greater than that in the agricultural industry sector.
This condition is presumed because Indonesia's agricultural commodities are primary commodities that do not have much product differentiation and can be substituted for imported agricultural commodities.
Thus, the price decline of imported agricultural commodities did not significantly increase domestic consumption because consumers only changed their pattern from domestic agricultural commodities to cheaper imported agricultural commodities.
In the meantime, agricultural industry commodities are relatively intensive commodities using capital with more product Therefore, the price decline in agricultural industry commodities increases the imported commodity consumption.
Meanwhile, domestic commodity consumption remains high, increasing total consumption.
Investments in the agricultural sector and the agricultural industry sector increased by 743% and 0.
176%, respectively, due to the import duty reduction policy by 50%.
The investment increment was driven by an increase in household income .

In terms of trade discrepancy, both export and import increased.
However, the 0.
export increase was smaller than the 0.
717% import increase, reducing the trade balance surplus.
This is in line with the increased foreign trade performance due to the import duty reduction, marked by the increase in imports, exports and the trade balance.
The import performance in agricultural and the agricultural industry increased by 0.
193% and 0.
201%, due to import duty reduction by 50%.
The import increase is allegedly due to the import duty reduction, causing imported commodities to be relatively cheaper than domestic commodities.
Consequently, domestic demands for imported commodities increased.
The pattern changes in commodity demands encouraged domestic producers to reallocate resources to more efficient productive sectors, generally the primary and potential-export commodities, so that exports increased.
The import duty reduction in agricultural and the agricultural industry increased exports by 0.
241% and 0.
The increase in imported commodities availability, especially raw materials and auxiliary materials at lower prices in the domestic economy, provided incentives for domestic producers to produce more export commodities at lower costs with higher competitiveness.
A higher increase in exports compared to the import would escalate the trade balance surplus.
The trade balance surplus increase by 699% and 0.
330%, due to the import duty reduction in both sectors.
Trade Transaction Cost Reduction The economic performance due to trade transaction cost reduction is presented in Table 3.

This is presumably because reducing trade transaction costs has lowered the costs of domestic commodity trade transactions, which are greater than the decrease of imported commodity trade transaction costs.
Thus, prices of domestic commodities at consumers' level become cheaper than imported commodities.
This increases domestic commodity demands, while imported commodity demands also continue The increase of both commodity demands raise supplies of composite commodities in Economic Journal of Emerging Markets, 12.

The declining trade transaction costs reduced the prices of composite commodities at consumer then, the composite commodity demands increased.
The increase of exports due to trade transaction cost reduction was low because import duty rates decreased.
This may be caused of trade transaction cost reduction in the domestic economy, causing the domestic trade transaction costs to be relatively cheaper than the export trade transaction costs.
Thus, it provided incentives for domestic producers to increase supply in the domestic economy which was relatively larger compared to export supply .
arked by increased production output.
The increase in imports due to trade transaction costs reduction was smaller than the import duty reduction.
Domestic commodities more accepted trade transaction cost reduction in the domestic economy than imported commodities.
Consequently, domestic commodities became cheaper than imported commodities.
This condition increased domestic commodity demands, which were larger than imported commodity demands.
Conversely, the import duty reduction was only accepted by the import commodities, causing the imported commodity prices was cheaper than the domestic commodities and leading to high import increments.
Combined policies of reducing import duty and trade transaction costs The simulation results of the combined policies between import duty reduction in agricultural or the agricultural industry and the trade transaction costs reduction on economic performance are presented in Table 4.

The Impacts of Trade Policies on the Poverty Incidence Changes in poverty were approached with poverty incidence indicators.
The poverty incidence calculation due to the policies are presented in Table 5.
Import duty reduction Table 5 exhibits that reducing import duty by 50% in the agricultural and agricultural industry reduced the poverty incidence in urban areas by 0.
However, poverty incidence increased by The import duty reduction by 50% in the agricultural industry reduced the poverty incidence in urban areas by 0.
05% while in rural area remained unaffected.
This indicates that the percentage of poor people in urban areas decreased due to the import duty reduction in agricultural or the agricultural industry, but the percentage of poor people in rural areas increased.
The poverty incidence at the national level increased by 0.
04% due to the import duty reduction in agricultural but decreased by 0.
02% due to the import duty reduction in the agricultural industry sectors.
This means that the import duty reduction in agricultural increased the percentage of poor people at the national level, while the import duty reduction in agricultural industry reduced the percentage of poor people at the national level.
It can be seen that urban households received benefits, but rural households relatively suffered losses due to the import duty reduction in the agricultural or agricultural industry sectors.
This indicates a tradeoff between economic growth and poverty due to the import duty reduction in the agricultural The economic growth increased along with poverty incidence.
Therefore, implementing import duty reduction in both must be accompanied by complementary compensation policies for poor households and groups above the poverty line to prevent the poverty incidence in rural areas worsening.

Urban Rural Rural households depending on the agricultural increased poverty in rural areas.
The import duty reduction in the agricultural caused domestic commodity prices higher than imported commodities.
This condition transferred household demands from domestic agricultural commodities to imported commodities.
so that demands of domestic commodities declined and caused a contraction in agricultural sectors.
This situation forced producers to reallocate their production to more efficient sectors, especially in export promotion sectors.
Unfortunately, less-skilled labor in the agricultural cannot easily move to experiencing expansion .
enerally the import promotion sector.
Therefore, the labor production factor in the agricultural based in rural areas would suffer losses due to the import duty reduction.
This finding was in line with the study by Davis and Mishra .
, suggesting that the theory of Stolper-Samuelson was not always consistent with the empirical reality.
The theory says that abundant production factors in a country will increase real income when a country opens their If less-skilled labor is the abundant factor in developing countries, the labor will receive the most pro-poor benefits.
According to them, .

Trade liberalization might reduce protection for un-skilled workers, making them poorer.
Meanwhile, according to Harrison .
, globalization produces winners and losers among poor In the same region, liberalization may reduce income of rural agricultural producers and increase the consumers' real income in rural or urban areas for the same commodity.
Import duty reduction by 50% in the agricultural industry at the national levels, in urban and rural areas, declined the poverty due to the increased households' purchasing power as a result of falling prices of composite commodities in the domestic economy and rising incomes.
Trade transaction cost reduction Reducing trade transaction costs by 25% dropped the poverty incidence in urban areas, rural areas, and at the national level by 0.

areas than those in the urban areas due to low infrastructure.
Therefore, the price decline and the increase of composite commodities availability in rural areas were greater than those in urban areas, causing households in rural areas be more profitable.
Trade transaction cost reduction significantly decreased the rural commodity prices.
Consequently, commodities from rural areas were cheaper than commodities from urban areas.
It increased the rural commodity demands and expanded the This aspect increased the labor income in the sector and declined poverty in rural areas.

22%, as a result of reducing import duty in agricultural and trade transaction and decreased by 0.
20%, 0.

34%, due to reducing import duty in agricultural industry and trade transaction costs.
The percentage of poor people at all level - urban, rural, and national decreased due to the combined policies.
The poverty decline was caused by the price reduction in composite commodities and the increase of each household's income.
The combined policies lowered prices and raised the availability of composite commodities.
encouraging more economic activities that could increase the households' income and then declined the poverty incidence.
The poverty decline due to the combined policies of reducing trade transaction costs and import duty in agricultural industry was bigger than that in agricultural sectors.
This is because the import duty reduction in the agricultural contracted in the and expanded the agricultural industry sectors.
The labor production factor in the agricultural industry was generally skilled labor, which easily moved to expanding sectors, increasing income, and decreasing poverty.
Meanwhile, the import duty reduction in the agricultural contracted the agricultural.
income of less-skilled labor production factor in the sectors declined since the less-skilled labor did not easyly move to expanding sectors.
Thus, the total decline in poverty incidence was relatively small.
Rural households received bigger benefits than urban households due to both reduction Low infrastructure made trade transaction costs in rural areas high.
Reducing trade transaction costs of rural areasAo commodities would expand rural-based sectors and increase the labor-production income.
Besides, it will further decline poverty in rural areas.

it means cutting trade transaction costs reduced the income distribution inequality at the national and rural levels, but not in urban areas.
Thus, rural households benefited more than urban households.
The decline of income distribution inequality in rural areas was because the costs in rural areas became cheaper than the trade transaction costs in urban areas.
Then, rural-based sectors became more efficient and then expanded.
The expansion led to the income increase in labor production factors.
the increased income of low household groups reduced the income distribution inequality nationally.

Reducing trade transaction costs is better than trade liberalization.
However, applying both policies eliminated negative impacts and increased the positive impacts of each policy.
Thus, the study recommends: .
implement trade liberalization policies in sectors that have positive impacts, including the agricultural and the agricultural industry sectors.
However, the implementation should protect poor households and groups above the poverty line in rural .
support trade transaction cost reduction by improving transportation infrastructure and simplifying trade bureaucracy along the products' distribution chain from producers to This improves economic performance, declines the poverty incidence and reduces the income distribution inequality.
combine trade liberalization with both import duty reduction and trade transaction cost reduction to minimize negative impacts and increase the positive impacts.
