Korea faces a challenging task of simultaneously reducing emissions of air pollutants and greenhouse gases (GHG). Since both are emitted from the same sources such as fossil fuel combustion and economic activities, there could be commonalities and interactions between the policies for reducing each of them. A static computable general equilibrium model is developed to observe the economic impact of policies for reducing air pollutants or GHG and the interactions between those policies in Korea. The results show that reducing one of the air pollutants, particulate matter 2.5 (PM2.5) emissions by 30% from the business-as-usual (BAU) in 2022 will lead to reduction of GHG emissions by 22.8% below the BAU level, exceeding the national GHG reduction target. Also, by achieving the domestic GHG reduction target, which is 32.5% below the BAU level by 2030, PM2.5 emissions will be reduced by 32.8%. The costs of reducing air pollutants and greenhouse gas are high, reaching from 0.34% to 1.75% of gross domestic product, and the reduction causes an asymmetrical damage to emission intensive industries. The sum of the benefits from air pollutants and GHG reduction is estimated to be 0.4 to 1.2 times greater than the costs, depending on the scenario.

In this study, parametric and non-parametric methods are employed to measure the total factor productivity (TFP) growth in the Korean manufacturing industry from 1993 to 2003. The analysis period contains both periods before and after the Asian financial crisis. The TFP growth rate is decomposed into different components. Also different elasticities are reported. By classifying the results by period and classifying a number of time invariant firm characteristics, such as sector, size, and location of firms, we observe systematic heterogeneity for each characteristic. We discuss the underlying causal factors. The results from a non-parametric approach are also compared with those of a parametric approach.Time trend, general index, production function, total factor productivity, chained multilateral index,

A comparative analysis on Korean manufacturing plants is performed by size of plants and sources of TFP growth are decomposed into entry, exit, and survival effects of plants, focusing on the pre-and post-crisis periods. Additional survival analyses investigate internal and external determinants of the survival of plants. The results indicate that the exit of small-and medium-sized establishments (SMEs) with higher productivity is becoming problematic in the post-crisis period. The improvements in large-scale establishments (LSEs) after the crisis appeared to occur generally in high-technology industrial sectors; SMEs in low-technology industries are suffering from a sluggish market selection process.j ere_470 512..538 JEL Classification Numbers: C33, C41, D24, L60, O30.

South Korea needs to actively implement work-family balance policies to increase both the low employment rate of women and the low total fertility rate. This study analyzes the quantitative benefits that the implementation of work-family balance policies provides to employees and employers. We conducted a choice experiment that asked 633 participants about their stated preferences for a hypothetical company with different work-family balance practices. The analysis was performed by using a hierarchical Bayesian model that considered preference heterogeneity according to the respondents' characteristics. The results indicate that the availability of parental leave provides benefits equivalent to an increase of 5.80 million won in annual salary and that offering childcare in the workplace has an effect equivalent to an increase of 5.37 million won in annual salary. Further, low-income groups, women, the younger generation, and parents of preschool children are most sensitive to the policy. Finally, small and medium-sized enterprises are less desirable to work for than large companies, but the implementation of work-family balance policies could change this preference.

Abstract:The Korean emissions trading scheme (ETS) has one special characteristic that makes it different from other schemes, such as the EU ETS. While the other schemes consider only direct emissions from fossil fuels, the Korean ETS also regulates indirect emissions arising from the consumption of electricity. The problem of double counting arises under this setting, in which emissions from the power sector can be accounted for twice, when electricity is produced and consumed. This study aims to compare design options on indirect emissions accounting for the Korean ETS using a computable general equilibrium model. Four scenarios are generated for options accounting for direct and/or indirect emissions and are evaluated in terms of efficiency and equality. The result shows that the ETS operates most efficiently when only direct emissions are considered. However, the option that includes both direct and indirect emissions produces a competent result in terms of equality by spreading the economic burden of emissions reduction among industries. We conclude that this option can be an alternative to meet the key purposes of the Korean ETS.
