위험 회피적인 유권자는 진보/좌익/사회정당을 선호할까? 본 논문은 위험 회피적 성향을 지닌 유권자가 어떠한 정치 성향을 지니는 지에 대한 실증분석을 수행한다. 영국의 British Household Panel Survey 를 이용하여 위험회피적 성향을 지니는 유권자를 구분할 수 있고, 1993년부터 2008년까지의 개인의 정당선택 자료를 수집하여, 위험선호도와 정당선택의 상관관계를 분석할 수 있다. 위험회피적 성향을 가지는 유권자들이 현직 정부를 선호한다는 status quo 편향을 실증적으로 분석해온 선행연구들과는 달리 본 연구는 위험회피성이 영국의 집권 정당인 노동당 지지에 어떠한 영향을 끼치는 지를 분석하였다. 위험회피적 성향을 가지는 유권자들은 닥칠 수 있는 위험에 대비하여 사회보장제도를 선호하는 경향이 있고, 이는 진보/좌익/사회정당이 내새우는 정책노선과 같기 때문이다. 실증 분석 결과 유권자의 위험회피성이 증가할수록 노동당을 뽑는 경향이 큰 것으로 드러났으며, 이는 status quo 편향을 통제하였을 경우에도 통계적으로 유의하다. 그러므로, 본 연구는 위험회피성과 진보/좌익/사회적 성향이 직접적으로 상관 관계가 있는지에 대한 실증적 논문으로서의 가치를 가진다. Do risk averse individuals indeed prefer left-wing parties? Risk averse individuals are believed to value more on social protections and redistribution policies which are often the main policy direction of left parties, towards possible risks they may face in the future. In this short paper, we present empirical results which suggest that risk averse individuals are more likely to vote for left-wing political parties such as Labour party in the UK, using data from the British Household Panel Survey (BHPS) from 1993 to 2008, where risk aversion could be identified and individual political preferences are annually collected. We distinguish this result from the previously reported finding that risk averse voters might prefer to reelect incumbent governments, as opposed to alternative parties. To our knowledge, this relationship has not been previously tested empirically and while our study focuses specifically on the UK political environment during a relatively short time period, it suggests that models that attempt to capture electoral decision-making could benefit from incorporating this effect.

Risk Aversion and Labor Decisions: A Comparative Study of Korea and France

( Seeun Jung ) 한국EU학회 2016 EU학연구 Vol.21 No.1

이 논문은 노동시장에서 개인이 어떻게 행동하는지, 특히 남녀격차가 왜 발생하는지 개인의 위험회피도를 이용하여 분석한 연구이다. 한국노동패널 (Korea Labor Income Panel Study)과 프랑스의 PSE Attitudes, comportements des Francais vis-a-vis de l`espargen 서베이 데이터를 이용하여 개인의 위험회피도를 측정하였다. 노동시장에서의 중요한 화두인 세가지 문제들을 (1. 교육수준, 2. 임금수준, 3. 직업군 선택) 개인의 위험회피도가 얼마나 설명 가능한지 분석하였다. 결과는 한국과 프랑스 양국에서 위험회피성이 높을수록 낮은 교육을 선택하고, 저임금을 받고, 안전하지만 저임금군인 직종에 머무르는 경향이 큰 것으로 나타났다. 한편, 노동시장에서의 남녀차이 역시 위험회피성으로 어느 정도 설명 가능 한 것으로 보인다. 통상적으로 여성이 남성에 비해 더욱 위험회피적인 성향을 가지는데, 이는 여성의 교육수준, 저임금군선택을 함에 있어 어느 정도 기여를 하는 것임을 알 수 있다. 그러나 남성에 비해 저임금을 받게 되는 결과를 초래하는 것을 설명하는 것에는 유의미한 결과를 얻을 수 없었다. 프랑스의 개인이 교육이나 직업선택에 있어서 위험회피성의 영향을 많이 받는 반면, 한국의 개인은 고등교육과 여성의 공공기관 직업에 대한 사회적 선호가 뚜렷하므로 위험회피성의 영향을 상대적으로 덜 받는 것으로 나타났다. 이는 한국과 프랑스의 노동시장과 사회적 함의의 차이점이 존재함을 시사한다. This paper investigates whether attitudes towards risk could explain how individuals behave in the labor market, and specifically whether gender differentials in the market could be explained by adding risk aversion as a factor in individual heterogeneity. I exploit data from the Korea Labor Income Panel Study (KLIPS) and PSE Attitudes, comportements des Francais vis-a-vis de l`espargne en 2009. To measure of risk aversion, I construct variables using several questions assessing attitudes towards risk. I investigate three questions: the impact of risk aversion on educational decisions, the impact of risk aversion on wages, and the impact of risk aversion on job sorting. The evidence indicates that individuals with high risk aversion tend to (1) pursue fewer years of schooling, (2) have lower wages in a Mincer regression, and (3) be sorted more into the public sectors that have higher levels of job security but also lower wages. This pattern is found in both the South Korean and French labor markets. Also, gender differences in the labor market seem to be partly explained by risk aversion. Women in general are more risk averse which may let them choose lower level of education and public sector jobs. However, risk aversion could not explain significantly why female wage is a lot lower than male`s. While risk aversion in French data can predict well the educational level and occupational choices, in Korea where the social preference towards higher education and women`s working in the public sector is large, risk aversion is not strongly significant in explaining their choices. This presents that there are differences in terms of labor conditions and social norms between Korea and France.

A Regression Model Tree Algorithm by Multi-task Learning

Seeun Jo,Chi-Hyuck Jun 대한산업공학회 2021 Industrial Engineeering & Management Systems Vol.20 No.2

To tackle the small sample size problem and difficulty reflecting a global effect in a model tree, this study proposes a regression model tree algorithm that employs multi-task learning. By applying multi-task learning considering the relatedness among terminal nodes when estimating a regression model tree, the proposed method prevents overfitting in a node with limited training data and considers both local and global effects. In addition, the multi-task learning algorithm used in the proposed method, interprets the relationship between different nodes. Experimental results on synthetic and real datasets demonstrate that the proposed method improves the prediction performance over baseline methods, particularly in small-sized nodes.

The Effect of Children's Age on Married Women's Career Reinterruption

Seeun Park,Sun Go 한국유통과학회 2018 The Journal of Industrial Distribution & Business( Vol.9 No.7

Purpose - The main purpose of this paper is to examine the effect of children’s age on maternal labor supply in Korea using survival analysis. Specifically, we focus on the career re-interruption of women having children under age 12, which has rarely been studied in the existing literature. Research design, data, and methodology - We use micro data from the Korea Labor and Income Panel Study (KLIPS) surveyed from 1998 to 2016. Instead of using a pre-school child dummy or the number of young children as an explanatory variable, 9 children’s age dummies are included to capture the effect of nurturing 0 to 9 years old children. This study estimates the hazard of a woman’s exiting the labor market after her first experience of the career interruption, rather than the hazard of the first career interruption itself. A Cox proportional hazard model is applied to numerically capture the impact of children’s age on behavioral changes in maternal labor supply. The sample used in this analysis is women between 15 and 54 years old. Most of all, we restrict the sample to women who had at least a child between 0 and 12 years old at the time of quitting their jobs. Results - The Cox proportional hazard model estimates show a strong negative effect of a 0-year-old child on maternal labor supply. Mothers with newborns have a high hazard ratio of labor force exit after the re-entry. The hazard of women with infants is three times higher than those with children aged 10 to 18. Additionally, the results show that not only newborns, but also children in the age of school-entry have a negative impact on their mother’s labor supply. Conclusions - The findings reveal that children’s ages need to be properly expanded and included when analyzing the effect of children and their ages on married women’s labor supply, especially on women’s career re-interruption. A large negative effect of 7-year-old children on maternal labor supply found here indicates that supporting mothers with school age children as well as pre-school children is necessary to prevent mothers from leaving the labor market.
