Revisiting the determinants of unit values

This paper studies the issue of how traded quantities affect trade prices, which has been relatively unexplored in the trade literature. By reproducing previous literatures' regressions which are based on the general equilibrium trade theories, incorporating the role of traded quantities, this paper shows a possibility of prevalence of the second degree price discrimination (quantity discount) in international trade, rather than the pricing behaviour of the general equilibrium theories.

The emission reduction effect and economic impact of an energy tax vs. a carbon tax in China : a dynamic CGE model analysis

Chinese government commits to reach its peak carbon emissions before 2030, which requires China to implement new policies. Using a CGE model, this study conducts simulation studies on the functions of an energy tax and a carbon tax and analyzes their effects on macro-economic indices. The Chinese economy is affected at an acceptable level by the two taxes. GDP will lose less than 0.8% with a carbon tax of 100, 50, or 10 RMB/ton CO2 or 5% of the delivery price of an energy tax. Thus, the loss of real disposable personal income is smaller. Compared with implementing a single tax, a combined carbon and energy tax induces more emission reductions with relatively smaller economic costs. With these taxes, the domestic competitiveness of energy intensive industries is improved. Additionally, we found that the sooner such taxes are launched, the smaller the economic costs and the more significant the achieved emission reductions.
