This study analyzed Korea's relations table through network analysis. In particular, among the centralities, eigenvector centrality, PageRank centrality and degree were used. The author studied which network characteristics affected the value-added rate.

A network analysis method was used.

It is the inward relationship that affects the value-added ratio of Korea's industries and the outward relationship has less influence. In particular, the inward relationship not only acts as a cost but also has an effect on the rate of added value recently.

Since the three years of 2010, 2015 and 2019 are the target, the data are somewhat insufficient to generalize.

As for the value-added ratio of an industry, input is more important than output (sales). Therefore, where the input is received is very important.

It is possible to increase the understanding of the determinants of the value-added rate of Korean industries.

(1) It was clarified which side is inward or outward in determining the industry in Korea. (2) The relationship between PageRank, eigenvector centrality and degree was analyzed in Korean cases. (3) Input is a cost and acts to increase added value.

During the Paris Convention, Korean Government made commitment to curb carbon emission by 37 percent by the year of 2030. Since then there has been constant debate, both in media and academia, as to whether attempts to reduce carbon emission would spell the concomitant economic slowdown. The purpose of this paper is to build a Computable General Equilibrium (CGE) model to see the effects of emission decrease on Korea economy.

To answer the above question, we build a comprehensive framework to gauge the economic impact of Paris Convention through the lens of Computable General Equilibrium (CGE) model using Armington and Melitz model.

Contrary to conventional wisdom, Korea’s economic performance in terms of welfare remains robust when the carbon emission is reduced. Broadly speaking, Korea’s welfare does not contract significantly in part due to expansion at the export market. For instance, the energy intensive industry (EIT) is affected most directly from the Paris Convention commitment and yet it experiences growth in export. On the contrary, the authors find that the general economic impact on Korea’s output is negative. The additional experiment using Melitz model shows that as the carbon reduction is enforced, both the number and the average productivity of the exporting firms increase in the EIT sector, which the authors refer in the paper as the “Melitz Effect.”

This paper shows that what can be occurred in Korean industries by emission decrease commitment.

One byproduct from restricting carbon emission is the surge in the electricity price. This is due to the fact that industries have to shift away from traditional fuels such as oil to electricity for energy. Therefore the authors propose that industrial policies aimed at balancing electricity price should accompany the plan to reduce carbon emission.

For Korean economy, the effects of emission reduction is researched using Armington and Melitz model at the same time. Especially, this is the first research case using the Melitz model in this Korean topic.

The purpose of this paper is to measure the effects of TPP on Korean economy focussing on the changes in the number of firms and productivity.

Following Melitz (2003) and Balistreri et al. (2011), the authors apply CGE simulation to five groups of 140 countries.

The authors find that welfare increases in Korea to join the TPP regardless the size of the TPP through productivity improvement of participating firms and increases in the number of exporting firms, factor prices and outputs.

This study helps tentative member countries of TPP decide to join.

The effects of TPP to Korean economy is measured with Melitz model, which has not yet attempted before.
