(1) Economic and environmental impact analysis of carbon tariffs on Chinese exports 共著 2015年 Energy Economics, Vol.50, pp.80-95
ABSTRACT: As an alternative measure for the proposal of border tax adjustments (BTAs) advocated by the countries that seek to abate CO2 emissions (hereafter referred to as ‘abating countries’), export carbon tax (ECT) voluntarily conducted by the developing countries has been widely discussed in recent years. This paper uses the multi-regional and multi-commodity computable general equilibrium (CGE) model and the GTAP8.1 database to investigate the economic and environmental effects of carbon tariffs on Chinese exports. The following three policy scenarios are considered: 1) the abating countries implement cap-and-trade emission programs without BTAs; 2) the unilaterally abating countries levy import tariffs and export subsidies on non-abating countries; and, 3) the abating countries implement unilateral climate policies combined with ECT imposed by China. The ECT policy of China is evaluated with a carbon price set at 17 US$/t-CO2. Results illustrate that the ECT voluntarily implemented by China is ineffective in reducing its domestic CO2 emissions. Moreover, ECT merely has a minor impact on global emissions. Finally, the competitiveness of China's energy-intensive and trade-exposed (EITE) industries suffers substantial losses if export tariffs are imposed. However, China's gains in terms of welfare and gross domestic product (GDP) would be slightly improved if an ECT policy is implemented, compared to the scenario where China is subjected to BTAs levied by the abating coalition. In the light of the tradeoff between tariff revenue for welfare and competiveness losses of the EITE industries, it is therefore difficult to conclude that carbon tariff on Chinese exports is an alternative policy to BTAs.

(2) Labor Value and Exploitation in the Global Economy 単著 2017年8月 Research in Political Economy, Vol.32, pp.15-37, doi:10.1108/S0161-723020170000032003
ABSTRACT: This paper discusses labor value and the rate of exploitation in the global economy using international input-output tables. Labor value is defined as the multiplication of the labor coefficient and Leontief inverse. Exploitation means that the amount of labor embodied in the received wage commodity is less than the amount of the labor actually sold. Therefore, the Fundamental Marxian Theorem, which states that the conditions for the existence of profit and those for the existence of exploitation are the same, should be modified to stipulate that the existence of profit requires exploitation in at least one country. In other words, exploitation may not exist in some countries (nonexploitation). In the context of international input-output tables, we introduce the concept of global labor value, which is the vector of embodied labor in various countries. In the empirical study using an international input-output table, we find that (1) there are non-exploitation cases in several countries. (2) During the time period 1995-2009, the rate of exploitation increased in Asian countries, namely China, Japan, Korea, and Taiwan, whereas the advanced countries other than Asia faced a decreased rate of exploitation.
Keywords: Exploitation; global economy; input-output tables; Fundamental Marxian Theorem; labor value

(3) Capital Accumulation, Vintage And Productivity: The Japanese Experience 共著 2019年6月 Singapore Economic Review, Vol.64,No.3,
pp.747-771, DOI: 10.1142/S0217590816500211
ABSTRACT: We empirically examine the relationship between capital accumulation, vintage and productivity of industries in Japan using firm-level microdata. Our analyses confirm that vintage significantly influenced productivity during the period of economic expansion. The effect was particularly notable during the upturn that started in 2000, when most examined industries displayed strong vintage effects. The rejuvenation of capital equipment during this period clearly resulted from a strong productivity effect. During the economic bubble of the late 1980s, by contrast, vintage exerted no observable effects on productivity despite significant increase in investment. This finding shows that an increase in capital stock during this period was not necessarily productive and likely produced a merely temporary boom. We reconfirm that the relation between vintage and productivity changed in subtle ways in response to the phases of business cycles.
Keywords: Vintage; embodied technology; productivity; business cycle.

(4) Impact of alternative regional trade arrangements on the Ethiopian economy 共著 2021年1月 Economic Structures 10, 2 (2021).
ABSTRACT: The Common Market for Eastern and Southern Africa (COMESA) is a Free Trade Area (FTA) regional trade agreement in Africa. Currently, Ethiopia is negotiating to join COMESA FTA. This study assesses the impact of three regional trade arrangements, COMESA FTA, customs unions, and the European Partnership Agreement (EPA) on the economy of Ethiopia. The analysis is based on a static Global Trade Analysis Project (GTAP) model, version 9 database. Unlike previous studies, the customs union scenarios are designed at the detailed Harmonized System (HS) level. COMESA FTA (scenario 1) with standard GTAP model results in a welfare loss for Ethiopia due to negative terms of trade and investment-saving effect, but with unemployment closure (scenario 2); Ethiopia enjoys a welfare gain mainly due to endowment effect. In scenario 3 (COMESA customs union) and scenario 4 (European Partnership Agreement), Ethiopia loses due to negative terms of trade and investment-saving effect. There is a large increase in demand for unskilled labor force in Ethiopia by around US$23 million, US$112 million, and US$43 million for scenario 2, 3, and 4 respectively. Moreover, there is a positive output effect for oilseeds, leather, and basic metals across all scenarios. The world, as a whole, enjoys welfare gains with COMESA FTA (scenario 1 and 2). However, with scenario 3 and 4, there is an overall welfare loss. There is no strong reason for Ethiopia to move to the customs union, and the EPA in the short run. Therefore, a transition period is necessary, but it is recommended for Ethiopia to join COMESA FTA.
