However, TFPG estimates showed an increasing trend in the 1990s when major economic reforms were implemented. The educational level of the labor force has improved consistently since the 1960s. However, based on the decomposition analysis the paper finds that its contribution to TFPG has declined.

On the basis of the results of his simulation runs, the author of this Policy Notes suggests that tariff reduction is generally pro-poor as shown by the drop in poverty incidence as a whole due to the increase in factor prices and decline in consumer prices. However, the simulation results also indicate that there is a bias in favor of factors employed in the manufacturing sector as industry expanded while agriculture contracted. More details are shown in this Policy Notes.unemployment, income distribution, computable general equilibrium (CGE), poverty, tariff reform

What are the effects on the local rice industry? How about on the poverty situation in the Philippines? On income distribution and on prices? The author presents the results of his simulation runs in looking at these effects.computable general equilibrium (CGE), agriculture sector, poverty, rice sector, Philippines

Between 1990 and 2013, the Philippines has lost 3.8 million hectares of its forest. This study carries out a quantitative assessment of the potential economic and poverty impacts of the NGP using a computable general equilibrium (CGE) model. In the assessment, a CGE model is specified, calibrated and used to simulate three scenarios: (i) a baseline or a business-as-usual scenario that incorporates the current forest deterioration in the Philippines; (ii) a full NGP scenario which implements a reforestation program that halts and reverses the reduction in the country’s forest cover; and (iii) a partial NGP scenario where only half of the 1.5 million hectare target reforestation is achieved. The assessment indicates that the NGP will result in an improvement in the overall output of the economy. The production of agricultural crops (palay, coconut, sugar, and other agriculture) improves...

One of the key focused areas is the trade sector. Policy reforms included tariff reduction, simplification of tariff structure, and tariffication of quantitative restrictions. While some of the reforms were pursued unilaterally, others were done under various multilateral agreements such as the World Trade Organization (WTO), and regional agreements under the Association of Southeast Asian Nations (ASEAN) such as the ASEAN Free Trade Area (AFT A). This paper aims to analyze the effects of the trade reforms, particularly tariff policies, on income distribution and welfare. The paper employs a computable general equilibrium (CGE) model calibrated to Philippine data in the analysis. vii

This paper discusses the structure of the Philippine computable general equilibrium model (PCGEM)... more This paper discusses the structure of the Philippine computable general equilibrium model (PCGEM). The model is a medium-sized CGE model of the Philippine economy. It disaggregates the production sector into 34 sectors. It incorporates 3 types of factor inputs: labor, variable capital and capital. The household sector is grouped in decile. Production differentiation is introduced in imports and exports. PCGEM is a neoclassical CGE model, with price clearing mechanisms. Furthermore, it is a full employment model. At its present state, the model is closed with fixed current account balance, fixed exchange rate (the numeriare), and endogenous PINDEX, which is the weighted value added price (or the GDP deflator). Also, savings go back into the system in the form of investments. The model is static and calibrated using the 1990 social accounting matrix and the 1990 sectoral tariff revenue. PCGEM is coded in a software called General Algebriac Modelling System (GAMS).

There are macroeconometric models, CGE-poverty microsimulation models, household models, partial/single equations models used by various analysts in private and public institutions and in the government planning agencies to conduct policy simulation exercises to analyze the distributional and poverty effects of adjustment policies. While the results guide the policy discussions on the poverty effects and provide policy framework for the medium-term development plan of the country, the ultimate impact on poverty would largely depend upon the specific government poverty programs, the targeting mechanisms, and the institutional arrangement that facilitate the implementation of such programs. The discussion in the paper indicates that there are large gaps in the poverty programs of the government and in the institutional arrangements. 9. Insights References Tables and Figures 1.

The approach relaxes the representative household assumption in the traditional CGE modeling by replacing household groups with individual households. As such the approach allows one to model the link between trade reforms and individual households and their feedback to the general equilibrium of the economy. The present paper incorporates the whole 24,797 households of the 1994 Family Income and Expenditure Survey and simulates the tariff reduction from 1994 to 2000. Tariff reduction leads to higher imports and exports. Although domestic production for the local market declines, the overall production improves. These are due to substitution and scale effects of tariff reduction. Resource reallocation and factor movements favor the nonfood manufacturing sector. Agriculture wages, as well the rate of return to capital in agriculture, decline as a result of the d...

The paper attempts to analyze the effects of the tariff reduction from 1994 to 2000 on household income and welfare using a computable general equilibrium (CGE) model calibrated to the 1994 social accounting matrix (SAM). Insights that can be drawn from the tariff reduction experiments include: (a) significant drop in domestic prices; (b) improvement in export competitiveness through the effective depreciation in the real exchange rate; (c) reallocation of production and resources towards the non-food manufacturing sector, which is a dominant sector both in trade and production; (d) drop in agriculture wages and increase in production wages; and (f) factor substitution favoring skilled production workers. The effects on nominal income are biased against rural households. This is largely because of the decline in agriculture wages and the...

The approach allows one to model the link between trade reforms and individual household responses, and their feedback to the general equilibrium of the economy. The present paper incorporates the entire 24,797 households of the 1994 Family Income and Expenditure Survey.

The series of simulation experiments indicate that tariff reduction is welfare improving. The transmission channel is not so much through the improvement in household income, but through the reduction in domestic and consumer prices. In terms of resource reallocation effects and factor movements, the nonfood manufacturing sector benefits the most. As a result, unemployment in production labor declines while its wages improve. However, agriculture sector contracts which results in higher unemployment in the sector and lower agriculture wages.

In the agreement, the original six ASEAN nations (Brunei, Indonesia, Malaysia, the Philippines, Singapore and Thailand) placed zero-duty on 99 percent of all their products in an inclusion list. However, they also put up a list of sensitive/highly sensitive products in which certain tariffs can be maintained. In the case of the Philippines, tariffs on rice and sugar were initially maintained at 40 percent and 38 percent. But in the ATIGA, the Philippines has committed to reduce its rice tariffs to 35 percent and its tariffs on sugar to 5 percent in 2015. In particular, through the Executive Order (EO) 892 signed by the Philippine president in 2010, the Philippines committed to reduce tariffs on sugar imports from the area from 38

These models are chosen as they represent the range of recently constructed CGE models of the Philippine economy. They also represent two schools of thought in CGE modeling:

The results indicate that while welfare rises and poverty falls for all household groups except the poorest (those with rural unskilled private employees as household head), urban households gain more than rural households. Policy experiments involving full tariff reduction and uniform five percent tariff rate indicate generally the same pattern of effects, except that the magnitude of change is relatively larger in the former while all household groups, including the poorest, experience a reduction in poverty in the latter. Since poverty remains high and the disparity between rural and urban poverty is still wide, other poverty-reducing measures have to be designed and implemented to target those households that do not benefit much from this type of market reform.
