The objective of the study was to explain the effect of job fit on life satisfaction of wage workers and verify the mediating effect of job satisfaction between two variables. For the purpose, 7,202 research subjects were selected from the 23th data of the Korean Labor and Income Panel Study. Selected data was analyzed by various methods including frequency analysis, descriptive statistics analysis, and correlation analysis. Moreover, the mediating effect was verified by applying SPSS Macro Model Number 4 analysis and bootstrapping method. The major findings are as follows. First, job fit of wage workers was shown to enhance their life satisfaction. Second, work satisfaction of wage workers was revealed to play a complete mediating role in the relationship between job fit and life satisfaction of wage workers. On the basis of the results, the various practical programs to increase life satisfaction of wage workers were discussed.

Recent discussions about a minimum wage increase (MWI) and its influence on the economy have mainly focused on the quantitative aspects, such as labor costs and employment. However, concerning the qualitative aspects, an MWI could have positive effects by enhancing firm productivity and crowding out marginal firms from the market. These positive effects of an MWI can offset, to some extent, its potential negative effects - increasing labor costs and decreasing employment, among others. In this regard we empirically examine the impact of an MWI on firm productivity (total factor productivity). Using firm level panel data from the manufacturing industry in Korea, we calculate the influence rates of a minimum wage by sector and by firm size (number of workers), and analyze its effects on firm productivity. In particular, the production functions of the firms are estimated by taking into account endogeneity among the input factors, in order to resolve the drawbacks of existing studies - underestimating the capital factor coefficient and overestimating the labor factor coefficient. This study finds that the influences of an MWI on wages, employment, and productivity are substantially different across sectors and firm sizes. While an MWI has shown to have positive influences on productivity growth in the manufacturing industry as a whole, each sector demonstrates a different direction of effect, and the degree of productivity change also varies by sector. The impacts of an MWI on firm productivity are generally estimated to be more negative for smaller firms, but in some sectors the effects are found to be positive. In addition, the wage increases resulting from an MWI seem to cause a productivity enhancement across all sectors in the manufacturing industry. The policy implications of this study are as follows. Considering the empirical findings that an MWI causes an increase in productivity in many sectors of the manufacturing industry, it would be desirable to take into consideration not only the negative side effects but also the positive effects of an MWI when designing any future minimum wage policy. Moreover, in spite of there being a uniform minimum wage, this study finds that the diverse influence rates of a minimum wage across firms have different impacts on wages, employment, and productivity across sectors or firm size. This finding could be conducive to discussions about differentiation among minimum wage schemes by sector or firm size.

In this research, an empirical analysis was performed to determine the correlation between management performance and R&D investment for domestic venture businesses in each industry. Specifically, an empirical analysis for each industry was attempted not only to clarify the general hypothesis on the relationship between management performance and R&D investment for venture businesses but also to demonstrate that differences exist for each industry. Empirical analysis was conducted for eight industries with respect to the $2002{\sim}2006$ panel data extracted as investigative results from the "Investigation Report on Science and Technology R&D Activities" published by the Ministry of Science and Technology. Industrial classification was limited to the middle-level classification (2-digit) in the Korea Standard Industry Code (KSIC) owing to the limited number of panels. Although this research only verified the overall positive effect of R&D activities and funds for existing research on corporate value or productivity and management performance, it was able to document the difference for each individual industry and each business size unlike existing research.Furthermore, the reliability of the research results was enhanced by targeting companies that have been continuously conducting R&D and management activities using consistent 5-year panel data in the analysis. Again, this was something that existing research did not have. Finally, through the use of recent data from 2002 after the IMF economic crisis up to 2006 in the empirical analysis, this research proposed the problems due to the prevailing circumstances at the time of entering the advanced nation stage based on an empirical analysis; the prevailing problems during the pursuit of advanced nation status before the IMF crisis broke out were not tackled. The key empirical analysis yielded several results. First, capital and size of the labor force have a positive correlation with the management performance for the entire company or the venture business. This applies to all eight industries as the subjects of the analysis. Second, although the number of years since a company has been established can have positive or negative correlation with management performance for the entire company or venture business in specific industries, a definite overall trend cannot be identified. Third, R&D investment can be said to have an overall positive effect on corporate management performance. Fourth, the size of the research staff cannot be said to be a factor unilaterally affecting the management performance of the entire company or the venture business. Fifth, the number of years a research institute has been in operation, which was assumed to have a positive effect on the management performance of a company because of the accumulated R&D know-how -- definitely acts as a positive factor contributing to the management performance of a company.

This study takes of youth panel data(2002-2003), there is the purpose to know to youth employed's labor mobility conditions of employment status conversion and examine on factors affecting conversion of employment status. Main analysis result and policy imply, is as following. First, although youth employed's non-standard employment shows some decrease, employment youth hierarchy was construed that youth of our country is consisting very changefully because appear great turnover that is converted by unemployment or Not economically activity population same period. Specially, non-standard employment phenomenon of woman or low in scholarship person appeared notedly, and because phenomenon that is converted by unemployment or Not economically activity population is expose that is deepened, discriminating policy of government dimension is required for employment stabilization of these class. Second, show result that danger to escape to non-standard job risk trap which seeking employment activity of youth class is arranged case or company which is formed by official path is suitable becomes low, must formulate path of employment about youth class and improve qualitative level of employment through suitable job placement education of youth class or function (technology) level. Third, when was construed, but take into account that the although large enterprise have low risk in non-standard job, recently employment of youth class consists very limited, rather small scale business or smaller enterprise's competitive power preferably need to be plan. Finally, danger to non-standard job youth employed's company form is government connection wonder was expose that high, Such result can do that it is difficult by limited research period, but reflect actuality that youth unemployment policy of our country is enforced laying stress on public labor or unregular job employment such as internship system. Therefore, current youth unemployment policy may have to change by employment policy that can secure stable work record by youth class or act as bridge-building that promote conversion by full-time job.

This study reviewed pension reform's overall characteristic and(anticipated) positive negative effect in OECD countries's and then analysed middle-old age's retirement transition and determinants of full/gradual retirement through the $3{\sim}7th$ Korea Labor and Income Panel considering that Korea has been aging society quickly and it is necessary to suggest not only solution of early retirement and working age reduction but also pension reform. As a result of this study, about 1/4 of 50 years and older have been continuing to work through various pathways after retirement and 98% among fully retired older who passed by re-employment step of occupational status including retirement are still searching for jobs. This showed that it is also inappropriate to typical retirement concept itself on the lines of labour market participation in Korea and part-time/temporary work or self-employment have been used by means of alternatives of maintaining works for middle-old ages. However, the duration of changed occupational status of gradual retirees is mostly only $1{\sim}2$ years. Therefore it is necessary to support the gradual retirement to minimize a term of income insecurity and promote the work of the old ages who have will and capacity of work. Most of all, partial pension system which is main program of gradual retirement, should make the rules that beneficiaries are those who age less than pensionable age and benefit levels should be actuarial fairness together with pension system and provide substantial help. But, the introduction of partial pension system is not the only way to solve and needs overall social economic approach. Especially guarantee the increase of quantitative qualitative employment for middle-old ages linking labor market policy and supporting gradual retirement not ought to be abused to force the part time works and early retirement route against their own will.

This study aims to explain the current upheaval in marriage that many young Korean men and women postpone or deny their marriage. In order to explain the delayed marriage, we need to understand the taste by which men and women choose their partners, the opportunity by which they find their ideational half in reality, and the context in which these values and opportunities of marriages intersect. This study examines the way in which the value and opportunities of marriage among Korean men and women have intersected differently in the changing economic conditions. Using KLIPS(Korea Labor Income Panel Survey, 1998-2002), differential effects of education and occupational status on marital time according to marriage cohort and gender are analyzed. Results find that the opportunity of marriage among men turns out to have been stratified significantly according to their educational achievement and labor status since the 1990s. For women, education and economic activities are likely to influence marriage decision in a discordant way; during the period of 1990-997, highly educated women are more likely than their counterparts to be married earlier while there is no significant difference according to economic activities. This implies that status homogamy has been intensified since the 1990s and many women with high motivation for social status are able to achieve a vicarious social status through marriage in a prosperous economy. For women married after 1998, however, the educational effect is insignificant but economic activity contributes to delaying marriage. This suggests that under the economic restructuring since the late 1990s, the constraint of opportunities finding decent jobs particularly for men results in the contingent change in women's perception about family roles and economic activities by reducing their expectation to achieve a vicarious status through marriage, but increasing their motive for their own economic activities.

This study examines the job and life satisfactions of the self-employed. It uses the Korean Labour and Income Panel Study(KLIPS, hereafter) data for 1998 and 2004. We examine the phases of satisfaction and what variables influence satisfaction for both years and compare the results in order to see what changed between the two regimes. We make use of k-means clustering to divide self-employed into similar degrees of satisfaction. As a result, we are able to classify the self-employed into three groups(low, medium and high) both for the two regimes. High groups consists of relatively younger, well-educated, low working dates, higher proportion of woman than other groups. As a result of regression analysis, we have some evidence that women are more satisfied than men for job satisfaction and that the existence of income is more important than the amount of income for life satisfaction. The age, education, satisfaction for working place, and health are significant to both satisfactions.

This study is to examine the effects of high commitment HRM on service performance in the service industry, and to examine the mediating effect of the organizational internal innovation direction. Specifically, the direction of internal innovation consists of high-value-added HR and service and cost-reduction downsizing. We assumed that the high-value-added direction of HR and service will have a positive mediating effect. And assumed that cost-reduction downsizing direction has negative mediating effect. The data were collected from 2013 workplace panel survey(WPS) of the Korea Labor Institute(KLI). Among the 1,775 companies, 896 companies classified as wholesale and retail, transportation, professional scientific services, education services, health social services, financial services, and other services (such as information society support services) were extracted and used. In summary, high-commitment HRM has a positively significant effect on the direction of high value-added innovation of HR and services, and has a negatively significant effect on the cost-reduction downsizing direction. In addition, the direction of high value-added innovation of HR and service was positive effect on service performance, and cost-reduction downsizing innovation direction has a negative effect on service performance. And the direct effect of high commitment HRM on service performance has not been confirmed. However, we confirmed the positive mediating effect of high value-added innovation direction of HR and services, and confirmed that the negative mediating effect of cost-reduction downsizing. Therefore, it is confirmed that the two variables have a full mediating effect on the relationship between high commitment HRM and service performance.

This study examines the effects of real exchange rate (RER) depreciation shocks on firm-level productivity and employment in Daegu-Gyeongbuk manufacturing industries during 2006-2012. In particular, the study focuses on a sharp and persistent RER depreciation of the Korean Won from 2007 to 2009, which is a situation akin to a natural experiment in Korea. We find that RER depreciation has positive effects on productivity for firms with high export exposure in foreign markets. However, these effects disappear when RER depreciation persists. In addition, we do not find evidence that RER depreciation affects employment of Daegu-Gyeongbuk firms significantly. Firms in Daegu-Gyeongbuk region should pursue core competency to obtain international competitiveness rather than depending on temporary better price condition driven by RER depreciation. Further, policy makers in a local government should provide firms with financial and investment support to encourage innovation and R&D.
