Abstract

This study uses a computable general equilibrium model to analyze various policy scenarios for a carbon tax on greenhouse gas emissions from petroleum fuels and kerosene in Ethiopia. The carbon tax starts at USD 5 per ton of carbon dioxide in 2018 and rises to USD 30 per ton in 2030. Different scenarios examine the impacts with revenue recycling through a uniform sales tax reduction, reduction of labor income tax, reduction of business income tax, direct transfer back to households, and use by the government to reduce debt. Because petroleum fuels and kerosene are a relatively small part of the Ethiopian economy, the carbon tax has quite small impacts on overall economic activity while having a notable proportionate impact on greenhouse gas emissions from these energy sources, depending on the recycling scenario. The carbon tax can raise significant revenue-up to USD 800 million per year by 2030. The impacts on the poor through increased cost of living are not that large, since the share of the poor in total use of petroleum fuels and kerosene is small. In terms of income effects through employment changes, urban households tend to experience more impacts than rural households, but the results also depend on the household skill level and the revenue recycling scenario.

Abstract

Many countries have introduced policy measures, such as carbon pricing, greenhouse gas offsetting mechanisms, renewable energy standards, and energy efficiency improvements, to achieve their climate change mitigation targets. However, in many instances, these measures overlap in ways that may dilute each policy's greenhouse gas reduction potential. This study examines how a renewable energy standard in the power sector would interact with a national emission trading scheme that is introduced to achieve a greenhouse gas mitigation target. Using a static, multiregional computable general equilibrium model of China to simulate policy measures, the study finds that the addition of a separate renewable energy standard policy would increase the economic cost for achieving a target level of greenhouse gas mitigation. The study concludes that although renewable energy standard policies promote the use of renewable energies, they are an economic burden from the perspective of reducing greenhouse gas emissions if a carbon pricing mechanism is in place.

Abstract

This paper provides a forward-looking view of trade and its relevance for Lesotho's medium- and long-term development. It does this through computable general equilibrium analysis of potential impacts based on specific trade-related scenarios. The scenarios include the potential loss of American Growth and Opportunities Act preferences and preference erosion against competitors through, for example, a United States-Vietnam Free Trade Area. An immediate loss of American Growth and Opportunities Act preferences would have a significant economic impact that far exceeds that of a potential future United States-Vietnam Free Trade Area. If these preferences were suspended in 2018, Lesotho would face a loss of 1 percent in income by 2020, relative to the baseline, and exports of textiles and apparel would drop by 16 percent. The computable general equilibrium simulations stress the need to strengthen efforts to support structural transformation leading to diversification of export products and markets, improving backward and forward linkages, and lowering trade costs. The simulations also indicate that trade facilitation measures leading to an average decrease in trade costs of 2 percent per year would eliminate the negative consequences of the loss of American Growth and Opportunities Act preferences in terms of the loss of income. The changing external environment is likely to offer new opportunities to Lesotho's export industries in the medium term, including through regional integration under the Continental Free Trade Area.

Abstract

The price of oil could play a significant role in influencing the expansion of biofuels. However, this issue has not been fully investigated yet in the literature. Using a global computable general equilibrium model, this study analyzes the impact of oil price on biofuel expansion, and subsequently, on food supply. The study shows that a 65 percent increase in oil price in 2020 from the 2009 level would increase the global biofuel penetration to 5.4 percent in 2020 from 2.4 percent in 2009. A doubling of oil price in 2020 from its baseline level, or a 230 percent increase from the 2009 level, would increase the global biofuel penetration in 2020 to 12.6 percent. The penetration of biofuels is highly sensitive to the substitution possibility between biofuels and their fossil fuel counterparts. The study also shows that aggregate agricultural output drops due to an oil price increase, but the drop is small in major biofuel producing countries as the expansion of biofuels would partially offset the negative impacts of the oil price increase on agricultural outputs. An increase in oil price would reduce global food supply through direct impacts as well as through diversion of food commodities and cropland toward the production of biofuels.

Abstract

The primary objective of this study is to analyze the impact on Bangladesh of increased market access in India, both within a static production structure and also identifying dynamic gains. The study shows that Bangladesh and India would both gain by opening up their markets to each other. Indian investments in Bangladesh will be very important for the latter to ramp up its exports, including products that would broaden trade complementarity and enhance intra-industry trade, and improve its trade standards and trade-handling capacity. A bilateral Free Trade Agreement would lift Bangladesh's exports to India by 182 percent, and nearly 300 percent if transaction costs were also reduced through improved connectivity. These numbers, based on existing trade patterns, represent a lower bound of the potential increase in Bangladesh's exports arising from a Free Trade Agreement. A Free Trade Agreement would also raise India's exports to Bangladesh. India's provision of duty-free access for all Bangladeshi products (already done) could increase the latter's exports to India by 134 percent. In helping Bangladesh's economy to grow, India would stimulate economic activity in its own eastern and north-eastern states. Challenges exist, however, including non-tariff measures/barriers in both countries, excessive bureaucracy, weak trade facilitation, and customs inefficiencies. Trade in education and health care services offers valuable prospects, but also suffers from market access issues. To enable larger gains, Bangladesh-India cooperation should go beyond goods trade and include investment, finance, services trade, trade facilitation, and technology transfer, and be placed within the context of regional cooperation.

Abstract

A global computable general equilibrium model is used to analyze the economic impacts of rising oil prices with endogenously determined availability of biofuels to mitigate those impacts. The negative effects on the global economy are comparable to those found in other studies, but the impacts are unevenly distributed across countries/regions or sectors. The agricultural sectors of high-income countries, which are relatively energy intensive, would suffer more from rising oil prices than would those in lower-income countries, whereas the reverse is true for the impacts across manufacturing sectors. The impacts are especially strong for oil importers with relatively energy-intensive manufacturing and trade, such as India and China. Although the availability of biofuels does mitigate some of the negative impacts of rising oil prices, the benefit is small because the capacity of biofuels to economically substitute for fossil fuels on a large scale remains limited.

Abstract

The study aims to provide insights to policy makers in measuring the impact of trade liberalization and regional integration measures on gender employment and wages. The study incorporates gender-differentiated employment and wages for selected South Asian economies across sectors to identify targeted value chains and economic activities, particularly among green trade sectors. This is the first major attempt to develop a gender-differentiated data set for South Asian countries, within the widely used Global Trade Analysis Project framework, to examine the nexus between trade, green economy, and gender. Two illustrative scenarios are examined. The first scenario examines a complete tariff elimination among the Bhutan-Bangladesh-India-Nepal grouping of countries in all sectors. The second scenario involves complete tariff elimination among countries in South Asia. The results indicate that a free trade agreement signed by all countries is likely to be more beneficial compared with only some countries signing the free trade agreement. Women's employment grows faster than men's employment, as most of the sectors that benefit due to these free trade agreements are women intensive. Growth in women's employment and wages in South Asia is consistent with growth in green sectors.

Abstract

As preferential trade agreements are growing in number and depth, assessment of their economic impacts has become more important to inform policy-makers facing a multitude of potential preferential trade agreements. This paper provides novel ex ante estimates of the impacts of two key preferential trade agreements currently negotiated by Indonesia, the largest economy in Southeast Asia. The paper then compares these estimates with those of other preferential trade agreements that Indonesia may negotiate in the future. To that end it, combines a dynamic, multi-country computable general equilibrium model and a microsimulation tool linking the macroeconomic results to household-level welfare. The results suggest that, among the preferential trade agreements considered, the European Union-Indonesia Comprehensive Economic Partnership Agreement (EU-CEPA) is expected to yield the largest gains for Indonesia in income, output, and exports. This result is due to a combination of large expected reductions in trade barriers and a high share of international trade between the partners. These macro effects translate into the highest expected income growth relative to the other preferential trade agreements at every point of the income distribution. However, the gains for the EU-CEPA are proportionately larger for richer households, unlike the other agreements considered. The regressive gains are mainly due to the increase in skill wage premia spurred by the additional demand for skill-intensive sectors, especially services.

Abstract

A macro-micro simulation framework that links a computable general equilibrium model with the survey-based global income distribution dynamics model can be used to assess the economic and distributional effects of macroeconomic shocks and policies. The methodology is used to assess the economic and subnational labor market impacts of a series of stylized trade policy options for the Sri Lankan economy over a 10-year time period. The analysis focuses on the impact of unilateral para-tariff liberalization, free-trade agreements with China or India, and a full-reform scenario. The simulation results show that more ambitious trade reform can result in larger gains in gross domestic product, poverty reduction, and exports, particularly in sectors employing a higher proportion of women. In the absence of additional policies, growth is not equally distributed. In all the scenarios in which the Sri Lankan economy grows, the distribution of gains is regressive. Increasing labor demand for skilled workers translates into a larger skilled wage premium - by as much as 1.1 percent with respect to the baseline. Implementation of full trade reform accelerates the concentration of economic activity in the western regions of Colombo, Gampaha, and Kalutara. Net employment gains in the western regions would increase from 111,000 to 136,000 in the full reform scenario by 2028 and with respect to baseline conditions.
