    • An Empirical Analysis on the Impact of Government R&D Subsidies on Employment of SMEs
      Wonhong Lee, Hee-Seung Yang


         This study empirically analyzes the impact of government R&D subsidies on employment of SMEs in Korea using data from Survey and Analysis of National R&D Program and KIS-Value DB. We compare government R&D recipients to a matched set of non-recipients with PSM and Panel DID methods, and find that the recipients hire more employees than their counterparts. In addition, we find evidence that recipients of more government R&D subsidies hire more employees than recipients of lesser. These findings highlight that consecutive government R&D support from a mid- to long-term perspective is necessary to accelerate the net job creation effect.

    • Multinational Firms¡¯ Demand for Tax Haven:Evidence from South Korea
      Hyelin Choi


         Recently, foreign direct investment in Korea has undergone changes in terms of investment purposes, target countries, and major industries. In particular, investments in tax havens have been rapidly increasing since 2010. This study analyzes the characteristics of firms that invest in tax havens using firm-level data from the Statistics Korea. The analysis shows that larger, capital-intensive, and active in overseas direct investment firms are more likely to invest in tax havens. Moreover, firms with higher intangible assets and more intra-firm transactions have higher demand for tax havens.

    • An Analysis of the Impact of COVID-19 on International Airline Services:The Case of Daegu Airport
      Joo Yeon Sun


         This study aims to empirically examine the flight frequency of airlines operating non-stop international flights. By employing data from 2019 to April 2023, the empirical results using model including the number of past flight frequencies suggest that airlines with experience operating existing routes operate more flights rather than new ones. The higher the share of international routes at Daegu Airport and the lower the market concentration of international routes, the more the number of flights increases. The number of flights by foreign airlines drastically decreases. Finally, the number of COVID-19 confirmed cases has no impact on international flight operations.

    • The Effect of Socioeconomic Characteristics on Individual Perceptions of Economic Inequality and Giving
      Seoyoon Jeong, Myungkyu Shim


         This paper explores how different individual socioeconomic characteristics impact their perceptions of economic inequality and actions of giving. Using the 2022 Yonsei-Yongwoon survey data, we find that individuals with high labor income tend to be more aware of prevailing economic inequality while willing to donate less. Those who possess one or more residential properties are less aware of inequality. Political ideology also effects perception differently, in that individuals having relatively progressive views believe income should be more equalized, while the opposite is observed for those with conservative views. These findings are robust throughout various robustness checks.

    • Climate Change Transition Risk and Monetary Policy Response: The Case of Korea
      Jiyoung Lee, Joon-Ho Hahm


         This study assesses the impact of implementing a carbon tax for a low-carbon transition in Korea, using the New Keynesian DSGE model by Diluiso et al. (2021) calibrated with Korean data from 2001 to 2020. We investigate transition risks under two scenarios: a timely, gradual transition and a delayed, radical one. Additionally, we examine the influence of different monetary policy reactions on transition costs. Results indicate that a delayed, radical transition results in higher volatility in macroeconomic and financial variables compared to a gradual transition. Notably, a more responsive monetary policy can help mitigate adverse impacts on stability.

    • A Study on the Estimation of the Probability of Payment of the National Tax Delinquents using XGBoost
      Youngwoo Jeong


         The aim of this study is to estimate the likelihood of payment of the national tax delinquents and it determinants using XGBoost, a kind of machine learning method. For doing this, a total of 434,494 cases of national tax delinquents information, which were entrusted to KAMCO for consignment collecting between 2013 to 2022, were used for empirical analysis. As a result of this analysis, it was confirmed that several variables such as total amount of arrears, female or not, delinquent¡¯s age were major factors to affect the possibility of payment of national tax delinquents, based on the Shapley Value. And also, it was found that the classification accuracy of XGBoost was about 10%p higher than that of the logistic regression model, and the F1 score also produced relatively excellent result. Therefore, it is certain that XGBoost model is superior to a traditional model for predicting the possibility to pay of the national tax delinquents. The contribution of this paper is to confirm that the possibility of payment can be estimated through machine learning method using actual data of national tax delinquents.
