The Impact

The required decarbonization of the energy system is a complex task, with ambitious targets under the Paris Agreement, and related policy analysis should consider possible impacts on the economy and society. By coupling the energy system model TIMES PanEU with the impact assessment model EcoSense and the computable general equilibrium model NEWAGE, we present an integrated assessment toolbox for the European energy system capable of internalizing health damage costs of air pollution while simultaneously accounting for demand changes in energy services caused by economic feedback loops. The effects of each coupling step are investigated in a scenario analysis. Additionally, CO2 decomposition analysis is applied to identify the main drivers to decarbonize the energy system. Our results show that integrating externalities forces the system to take early action, which provides benefits on the societal level. Including macro-economic variables has a negative effect on energy service demands and generally reduces the need for structural change, which are still the main drivers of decarbonization. The tighter the models are coupled, the fewer the iterations needed and the lower the CO2 prices resulting from the carbon cap and trade system. In this aspect, an integrated view can provide valuable insights to determine efficient and effective decarbonization paths.

The Impact

Goods and services tax (GST) has been a controversial topic in Malaysia when it was first implemented. This study examines the impact of the GST on the Malaysian economy from three major perspectives. First, it investigates the consequent changes in sectoral responses, including output and prices for 15 main sectors. Second, the study presents the results of GST impact on seven macroeconomic variables, namely, consumption, investment, government revenue, government expenditure, export, import, and gross domestic product. Third, the results of household welfare are discussed. A computable general equilibrium model is utilized to simulate GST impact on the Malaysian economy, and a simple comparative static model is performed. The results prove that the higher the GST rate, the higher is the impact on each sector. The sectors most affected by GST are communication and ICT, and the electricity and gas sectors. By contrast, agriculture, forestry and logging, and the petroleum and natural gas sectors are the least affected. Consumption and investment receive the largest negative effect, whereas government revenue and expenditure show the largest positive effect. The study likewise finds that by lowering GST rate, the welfare loss was minimized and the higher-income groups were affected more than the lower-income groups.

AbstractClimate regulations tend to target energy-intensive sectors whose products are widely used in industrial production as intermediate inputs, and carbon abatement may be partially offset by intermediate input-led leakage. This paper aims to examine the impact of intermediate input linkages on carbon leakage both theoretically and empirically. The theoretical part develops a Harberger-type model with an input-output linkage structure, identifies four leakage effects and derives closed-form solutions for these leakage effects. Its empirical part builds a computable general equilibrium model of China's economy and introduces structural decomposition analysis to link the theoretical and empirical models. When imposing a carbon price on the electricity generation sector, our results show significant sectoral carbon leakage. Our decomposition analysis further suggests that such leakage is mainly through the production substitution effect and the multiplier effect. Our results highlight the importance of sectoral linkage when discussing the carbon leakage issue of climate policies.

The purpose of this study is to evaluate the impact of public expenditure cuts on employment and income to support policies for the development of the labor mar- ket. Impact evaluation is of interest for policy makers as well as researchers. This paper presents a method – that is based on a Computable General Equilibrium model – to analyse the impact of the public expenditure cuts policy on employment and income in industries and occupations in Vietnam using macro data, the Input output table, 2006, 2008 and the 2010 Vietnam Household Living Standard Survey.

Change Mitigation

This paper proposes the use of decomposition analysis to assess the effect of local energy-related actions towards climate change mitigation, and thus improve policy evaluation and planning at the local level. The assessment of the impact of local actions has been a challenge, even from a strictly technical perspective. This happens because the total change observed is the result of multiple factors influencing local energy-related greenhouse gas (GHG) emissions, many of them not even influenced by local authorities. A methodology was developed, based on a recently developed decomposition model, that disaggregates the total observed changes in the local energy system into multiple causes/effects (including local socio-economic evolution, technology evolution, higher-level governance frame and local actions). The proposed methodology, including the quantification of the specific effect associated with local actions, is demonstrated with the case study of the municipality of Malmö (Sweden) in the timeframe between 1990 and 2015.

Abstract On 5 October 2015, the Trans-Pacific Partnership Agreement (TPP) led by the U.S. was signed. Already, 12 countries1 have joined the agreement, but China has not. Thus, lots of research has focused on the negative effect of the TPP on China’s foreign trade. On the other hand, China is moving forward in its own efforts to establish bilateral free trade agreements (FTAs) and free trade zones. In June 2015, China-South Korea and China-Australia signed bilateral FTAs which went into effect in December 2015. Several questions were raised: Since South Korea and Australia are the major trade partners in the Pacific area and the bilateral FTAs will be effective before the TPP, will these FTAs’ positive effects on China’s foreign trade offset some of the negative effects of the TPP? If China and the U.S. adopted a competitive trade policy, which countries would benefit? If China and the U.S. adopted a cooperative trade policy, how would the trade value and economic welfare change? This paper simulates and analyses the mutual effects of China-South Korea and China-Australia FTAs and the enlarging TPP using the computable general equilibrium model. The major conclusions drawn suggest that China-South Korea and China-Australia FTAs will significantly offset the TPP’s negative effect on China’s foreign trade. If China is not included, the U.S. economic benefit from the TPP will be limited. The economic welfare for a country like Australia, which joined both the bilateral FTA and the TPP, will be increased the most. In the long run, China joining the TPP would be the most beneficial decision for its national interest. However, if the TPP cannot be approved by the US congress, the U.S.’s economic indicators and export would be decreasing sharply. China’s economy and export will benefit from FTAs.

The Impact

This paper uses a relatively new approach to quantify the effects of trade liberalisation on poverty.  It relies on the combination of a standard, social accounting, matrix-based, computable general equilibrium model and household micro-data. These two tools are used sequentially in order to simulate the impact of trade policy reform.  This framework enables the decomposition of the effects of trade liberalisation, which in turn allows for an analysis of alternative social policy packages.  The methodology is applied to Zimbabwe for illustration.  The results show that poverty is reduced by tariff reduction, although the poor households get the least benefits.
