Using detailed data of women's work history, this study analyses the transition process between employment and non-employment over the life history in order to identity individual and structural determinants in the processes. Korean women comprise very heterogeneous groups in terms of work continuity: one group having a continuous work history and another having an interrupted work experience. While 4.0% of total women have stayed in the labor market since leaving school, 17.3% have not worked outside at all and remaining 87.9% have experienced into and out of the labor market at least once. On the average, the cumulated time of employment per woman is 8.2 years and the cumulated time of unemployment is 13.1 years. Thus Korean women work a total of only 38.5% of their whole lifetime after leaving school. We can conclude that the increase of the employment rate of married women in Korea since the 1970s has been due to the increase of the new entrants with short or little working careers into the labor market, not to the increase of women's work continuity on the whole. A women's educational achievement does not seem to be positively related to employment duration, contrary to the suggestion of the human capital theory, Rather, family variables, especially the existence of the child under 6 yens old, is a more significant determining factor for an individual's exit from employment. And there is little difference among different age cohorts which implies little improvement in the employment continuity of younger women. This study also documents the importance of structural variables, such as the type of occupation, as significant determining factors for the hazard rate. Specially women with professional jobs tend to stay longer in the labor market. Therefore, women's entry into more professional occupations is expected to contribute to the continuity of employment. Our results also show that duration-dependence is not spurious. When unobserved heterogeneity is controlled, the negative relation between the rate from employment and the duration of employment does not disappear.

This study attempted to empirically investigate the determinants of poverty transition of the working poor with disabilities from a dynamic perspective. Analyses were conducted on the data from Panel Survey of Employment for the Disabled(PSED, Year 1-6), included the households with a disabled head of household. The working poor were defined as the household of which income fell below 120% of the absolute poverty line among the households just described. As results, The 6-year mean poverty rate for the working poor with disabilities included in the analysis was 31.4%, approximately three times of the poverty rate of the total population and the working poor with disabilities were found to have greater difficulty with poverty exit once having fell into poverty than all households living in poverty. And it was found that the economic activity factor was the key determinant of in-work poverty. In addition, employment of the working poor with disabilities did not lead straight to poverty exit, and the quality, rather than the status of, employment was the key determinant of poverty exit. The implications of the findings of this study are that it is essential to increase decent jobs, expand the social safety net of the working poor with disabilities and establish poverty reduction measures for each class of the working poor with disabilities to exit from poverty.

This study uses the youth panel survey (YP2007 2th ~ 9th) data of the Korea Employment Information Service to examine the phenomenon of subjective mismatch arising from the youth labor market and analyzed the determinants and wage effects of subjective mismatch. Overall, the analysis showed that the over-education and over-technology of both educational background and technical skill level in the Miss Match significantly decreased, while the lack of education and technology increased rather gradually. Next, the analysis of the determinants of downward employment(Excess of education and technology) showed that males were less likely to be downwardly employed(Excess of education and technology) than females, and in the status of workers, the probability of downward employment of regular and non-wage workers was lower than that of temporary/daily workers. Finally, as a result of estimating the wage effect of the mismatch based on the pooled OLS model and the Panel Fixed Effect model, the mismatch which has the greatest effect on the wage was found to be excessive education, and it has been estimated that youth employees who are over-educated have an average 6.7% lower wages than those who are not. After controlling for the unobserved individual characteristics, they were found to receive a lower wage of 3.2%, and it is estimated that 2.9% for the technical excess mismatch and 2.3% for the major mismatch receive lower wages than the reference group.

Until recently, self-employment workers are often excluded from labor market studies. Most relevant studies has focused on the determinants of entry into self-employment. However, the self-employment is highly exposed to poverty risk although they are working. Despite that, relatively little is known about the economic severity of the self-employed. This study uses data from the Korea Welfare Panel Study to examine the situation of the self-employed's in-work poverty and the determinants of in-work poverty among them. Major findings are as follows. First, self-employed people experience 3.5 times higher in-work poverty risk than employees. Especially, the ratio of own-account self-employed people living below the poverty line is similar with that of even precarious employees. Second, the extent of poverty of self-employment is more serious. Third, the proportion of self-employed among working poor is about 53% although self-employed workers are composed of only about 24% among working people. Fourth, temporary employees and self-employed people are more likely to be poor than full time employees according to logistic regression. It is statistically significant. It implies that it is desirable to regard the self-employed as the policy target group along with temporary employees. Fifth, the ratio of in-work poverty of self-employed aged 40-64 whose education level is low and the self-employed aged 40-64 who work in low-skilled service sector are higher than that of the other group. It implies that measures to alleviate their economic difficulties are urgently needed.

The developing countries have a lot of dormant resources, attempting the take-off of economic growth. The theory of 'vent for surplus' and Lewis model provide a good cornerstones to analyze the effect of export, FDI and domestic production on employment. This paper attempts to do empirical test to figure out what factor is significant as the determinant of Chinese employment. For this test, the estimation equations are derived from the Cobb-Douglas production function. The results are that the domestic production affects the most positive employment, compared to FDI and export. Unlikely general expectation, export doesn't have an substantial effect on employment in China. It is also found that the absorption of technology through export is lower than that of FDI in terms of the effect of technology on employment. So it is suggested that the employment policy should be shifted toward the increase of domestic production by using FDI rather than by promoting export industry. to reduce the internal imbalance.

Purpose - Recent issues such as vessel enlargement, strengthening of environmental regulations, and port smartization are expected to increase costs and intensify competition in the port industry. In the new normal era, when external growth has reached its limit, the efficient operation of ports is becoming indispensable for achieving sustainable growth. This study aims to identify the determinants of inefficiency by examining the cost structure and efficiency of container terminals in Korea and furthermore propose the political implications to derive the maximization of efficiency. Design/methodology - This study estimates the cost function of container terminal operators and identifies the efficiency of container terminals using stochastic cost frontier (SCF) in the first stage. In the second step, the SCF results are compared with the data envelopment analysis (DEA). Last, this paper proposes efficiency determinants on container terminal operation to establish appropriate strategies. Out of the 29 container terminal operators in South Korea, 13 operators participated in the survey. The translog cost function was estimated utilizing a total of 116 observations collected over the 2007-2017 period. Findings - Empirical analysis shows that economies of scale exist in Korea's container ports, which provides a rationale for the government's policy to establish the global terminal operator by integrating small terminal operators to enhance competitiveness. In addition, as a result of the determinants analysis, container throughput, weight of direct employment costs, and labour cost share have positive effects on improving cost efficiency, while inefficiency increases as the length of quay increases. More specifically, cost efficiency improves as the proportion of direct employment costs to outsourcing service costs increases. Originality/value - This study contributes to analyzing the inefficiency factors of container terminals through efficiency analysis with respect to a cost function. In addition, this study proposes the practical and political implications, such as establishing a long-term manpower pool, the application of the hybrid liner terminal system, and the construction of a statistical data system, to improve the cost inefficiency of terminal operators.

This study examined the aging of people with severe disabilities experiencing relative alienation and deprivation in an aging society to find ways to make them happy and economically stable. This study identified the determinants of economic preparation for aging among people with severe disabilities using the ecosystem perspective. For this study, data were drawn from Panel Survey of Employment for the Disabled (PSED). A total of 950 samples were used from the eighth wave. Logistic regression analysis was conducted to examine the influence of various factors. As a result, age, level of education, employment, subjective socioeconomic status, self-esteem, income, homeowner, and non-beneficiaries affected the economic preparation for aging. These findings have practical and political implications concerned with improving the economic preparations for aging among people with severe disabilities.

Although economic crisis is allaying in Korea, the more effective unempoyment policies are requried in this present. So in this paper, we analyze the effects of relevant factors, especially job search behaviors of the unempyoed on reemployment and look for implications to the improvement of unemployment policies. Major findings are as follows: First, we find that job search behaviors, especially the effectiveness of job search activity and job search attitude are significantly different between the unemployed and the re-employed. Second, we find that the variables of job search behaviors - the effectiveness of job search activity (number of job offers), job search attitude (reservation wage), positive use of job search methods - significantly affect the re-employment of the unemployed from logistic regression analysis results. These findings' implications are as follows: First, the approach based on search theory may be useful in finding out determinants of re-employment. Second, the effects of job search behaviors on the reemployment and their implications should be actively accepted to policy makers in order to improve the effectiveness of un-employment policies. It meams that the effects of job search behaviors must be carefully considered in making or restructuring unemployment policies and their administrations.

In this paper, we examine factors of success in online P2P (peer-to-peer) lending auctions. This paper finds the following empirical results. First, loan applicants with a stable employment status are more likely to succeed in the auction than loan applicants with an unstable employment status. Second, loan applicants, who actively share personal information and interact with lenders through online message boards, are likely to succeed in the auction. Third, the purpose of a loan for debt repayment has a significant impact on the success of the auction. However, the purpose of a loan for essential living expenses such as housing, living, and medical expenses has an insignificant relationship with the success of the auction. Our results imply that the characteristics of loan applicants such as employment status and social interaction are the factors of success in online P2P lending auctions.

Using a panel data of Korea for $1979{\sim}2002$, this study investigates the determinants of the service sector employment share in Korea. In order to analyze the impact of macroeconomic factors on the service sector's employment share we estimate a simple panel model which is in line with Baumol's model. The panel GMM estimation results show that: 1) The increase in the share of service-related jobs in total employment tends to rise with GDP per capita, which confirms demand-bias hypothesis proposed by Clark. 2) We find that a crucial role in this process has been played by the productivity gap. As Baumol's hypothesis or Baumolis disease, the expansion of the employment share in services relative to industry is the direct consequence of services' lower productivity performances.
