We develop an identity choice model within the context of a stereotyping-cum-signaling framework. The model allows us to explore implications of the fact that, when individuals can choose identity, then the distribution of abilities within distinct identity groups becomes endogenous. This is significant because, when identity is exogenous and if the ability distributions within groups are the same, then inequality of group reputations in equilibrium can only arise if there is a positive feedback between group reputation and individual human capital investment activities (Arrow, 1973; Coate and Loury, 1993). Here we show that when group membership is endogenous then the logic of individuals' identity choices leads there to be a positive selection of higher ability individuals into the group with a better reputation. This happens because those for whom human-capital-investment is less costly are also those who stand to gain more from joining the favored group. As a result, ability distributions within distinct groups can endogenously diverge, reinforcing incentive-feedbacks. We develop the theoretical framework that can examine the positive selection and the endogenous group formation. The model implies that inequality deriving from stereotyping of endogenously constructed social groups is at least as great as the inequality that can emerge between exogenously given groups.

With questionnaires conducted for 613 adult Koreans in Seoul, the present study examined how their social features (income level, political party identification, political values, values of capitalism and egalitarianism) exercise influence on attitudes toward income polarization and their evaluation of government policies. Two groups of participants (high vs. low) for each social feature were formed first. Then their attitudes toward income polarization (liberal vs. conservative) and evaluations of policies (liberal vs. conservative) exercised by government (Participatory vs. Practical) were compared. Results indicated that liberal value was strengthened by liberal value, anti-capitalistic, and conservative value was strengthened by egalitarian values, and party identification. It was also found that party identification partial effect on the judgment of policies exercised by Participatory Government. These findings were discussed in terms of their implications for Korean society and measures for communication constructive for settlement of income polarization were suggested.

National highway is one of the social infrastructures that continue to be managed in order to serve their full functions. The national highway has been managed by the Pavement Management System (PMS) until now. The PMS manages the highway as a way of facility maintenance and maximizes the service life of the highway with minimum cost. The cost is evaluated mainly with a facility manager's perspective based on engineering judgment. People's needs of quality of life have been increased as their income level is rising and naturally the opinion of citizen as a taxpayer plays an important role in determining national policy. Therefore, the contentment of a user's perspective was the starting point of addressing these needs. The Level of Service began to be used as a measure for the evaluation of the user's perspective. In this thesis we would like to design an application and a data architecture for a pavement asset management system and to show how it meets the requirements of KTAM-40 Systems.

The optimum population of a society or country can be defined as 'the population growth path that maximizes the welfare level of the society over the whole generations of both the present and the future, under the paths allowed by its endowments of production factors such as technology, capital and labor'. Thus, the optimum size or growth rate of population depends on: (i) the social welfare function, (ii) the production function, and (iii)demographic economic interrelationship which defines how the national income is disposed into consumption(birth and education of children included) and savings on the one hand and how the demographic and economic change induced thereby, in turn, affect production capacities on the other. The optimum population growth path can, then, be derived in the process of dynamic optimization of (i) under the constraints of (ii) and (iii), which will give us the optimum population growth rate defined as a function of parameters thereof. This paper estimates the optimum population growth rate of Korea by: specifying (i), (ii), and (iii) based on the recent development of economic theories, solving the dynamic optimization problem and inserting empirical estimates in Korea as the parametric values. The result shows that the optimum path of population growth in Korea is around TFR=1.81, which is affected most sensitively, in terms of the size of the partial elasticity around the optimum path, by the cost of children, share of capital income, consumption rate, time preference, population elasticity of utility function, etc. According to a survey implemented as a follow up study, there are quite a significant variations in the perceived cost of children, time preference rate, population elasticity of utility across different socio-economic classes in Korea, which implied that, compared to their counterparts, older generation and more highly educated classes prefer higher growth path for the population of Korea.

This study empirically examines if there is a certain linkage between the production regimes and welfare systems; and if linked, how they are linked. It also investigates what the different regimes performed in terms of economic growth and redistribution. As a matter of fact, we have a series of studies that explores structural diversity of production and welfare. However, the existing studies are limited in that they consider only specific facets of the structure, although the structure of welfare capitalism should be studied as a comprehensive whole. This is the gap which this study tries to overcome. The study is composed of two major parts. The first one is the cluster analysis that examines if Esping-Andersen's notion about three different welfare regime and the thesis of diversity of capitalism can be dealt within a single research framework. The second is the ANOVA analysis investigating if variables of production and welfare are to be statistically different in the trichotomy framework. According to the result of the analyses, we can find at least two important evidences about institutional complementaries of production and welfare. First, Esping-Andersen's framework is useful to comprehensively deal with production as well as welfare. Secondly, there are statistically different regimes of production and welfare in the context of political economic and social policy variables. What is the most striking conclusion of the study is that there is no difference among the regimes in terms of the level of economic efficiency; while we can find a huge differences in terms of the level of welfare effectiveness. In conclusion, there is no substantive evidence to argue that welfare is innately antithesis of economic growth.

The purpose of this study was to confirm the relationship between positive psychological capital, professor support, and the career preparation behavior of college students, and to identify the factors influencing the career preparation behavior. The convenience sampling method was used on 180 students from August 30 to October 30, 2020, Data was collected using a structured questionnaire and analyzed by frequency, percentage, mean, standard deviation, t-test, ANOVA, Scheff test, Pearson's Correlation Coefficients, and multiple regression. The research results showed that there were significant differences in positive psychological capital and professor support according to gender, majors, and economic levels. There were significant differences in career preparation behavior according to gender (t=3.52, p<.001), major (F=10.85, p<.001), and career decision (t=4.98, p<.001). There were significant differences in career preparation behavior according to gender, majors, and career decisions. Positive psychological capital (r=.45, p<.001) and professor support (r=.40, p<.001) showed a positive correlation with career preparation behavior. Factors influencing career preparation behavior were majors, career decisions, positive psychological capital, and the explanatory power of these factors was 32.5%. Therefore, effective career and counseling guidance should be planned to increase positive psychological capital according to the major. It is necessary to provide opportunities for exploration of various career options to enable students to select suitable careers or jobs and to set goals, and provide an environment with positive motivation.

The purpose of this study is to review the relationship between psychological capital and organizational commitment/ innovative behavior, and the moderating effect of organizational support. In order to verify and achieve the purposes mentioned above, questionnaire data were gathered and analysed from 315 professors and teachers of Korea Politechnics Colleges. Multiple regression and multiple hierarchical regression analysis were applied to test the proposed hypotheses: 1) the relationship between psychological capital and organizational commitment, 2) the relationship between psychological capital and innovative behavior, 3) the moderating effect of organizational support on the relationship between psychological capital and organizational commitment, 4) the moderating effect of organizational support on the relationship between psychological capital and innovative behavior. Empirical survey's findings are as follows; First, self-efficacy and optimism appeared to be positively related with organizational commitment, and all psychological capital factors(self-efficacy, resilience and optimism) appeared to be positively related with innovative behavior. Second, organizational support appeared to have moderating effect partly on the relationship between psychological capital and organizational commitment, but it did not have a moderating effect on the relationship between psychological capital and innovative behavior. Self-efficacy and optimism appeared to be more positively related with organizational commitment in higher organizational support situation than in lower organizational support situation.

This paper analyses how China is likely to be able to sustain its current pace of growth. The results of analysis show that China's economic growth matches standard growth patterns identified by the models of economic development such as structural change, catching up model. Furthermore, China's economic growth, within these analytical frameworks, matches those of Korea at an earlier stage of her development. So Korea's growth patterns may well apply to the future of China such as the benefits of free society with economics and politics which generate technical progress and innovations. A country with a high innovative capacity is one whose institutions - educational, economic, political, legal, and so forth - allow it to dynamically and continually generate new products and services in a myriad of sectors. These are the way how China is likely to be able to sustain her economic development.

The purpose of this study is to reanalyze the impact of college education in the Korean economic growth during the period 1971-2017. The study estimates the impacts of monthly average income per worker without college education with respects to the ratio of workers with college education to worker without college education, capital per worker without college education, and the number of patients per worker with college education. The results showed that the effect of the ratio of workers who had college education was 0.433 at 5% of significant level. In addition, it was estimated that the effect of the capital for each worker who didn't have college education was 0.45646 at 1% of significant level. These findings are similar to the results in the previous study of Kim and Lim. Finally, the number of patents per worker who had college education was estimated. Unfortunately, the coefficients on these were not statistically significant except for one period. Therefore, it is concluded that there is a positive spillover effect from the college education in the Korean economic growth.

As Korean society becomes more matured, more people consider trust valuable, as a social capital. Researchers introduced trust literatures focusing on public policy, sociology than business. In this paper, it is empirically analyzed how Organizational Justice, Shared Values, Organizational Trust, 3 dimensions of social capital explained by Nahapiet & Ghoshall, together with Job Satisfaction and Innovative Behavior, as a proxy of performance at the organizational level. The results of this study are as below. Firstly Organizational Justice, consisted of 4 sub-variables of Distributional Justice, Procedural Justice, Interpersonal Justice and Informational Justice, classified by Colquitt, affects Job Satisfaction positively. Secondly Shared Values, consisted of 2 sub-variables of CEO's Core Value and Organizational Culture, availing Competing Value Model of Cameron & Quinn, affect Job Satisfaction positively. Thirdly Job Satisfaction, consisted of 2 sub-variables of economical satisfaction and self-efficacy, affects Innovative Behavior positively. Lastly Organizational Trust has mediating effect on the relationship between Job Satisfaction and Innovative Behavior. However, while the direct effect of Job Satisfaction on Innovative Behavior shows 69%, the indirect effect of Organizational Trust on Innovative Behavior shows 31%, which may not be ignorable. Furthermore in case of smaller organization with less than 30 members, the indirect effect of Organizational Trust shows 64%, comparing to 36% of direct effect of Job Satisfaction. This study was able to confirm that organizations need to maintain Organizational Trust as much as they strive to increase Job Satisfaction through securing Organizational Justice and Shared Values in order to effectively increase Innovative Behavior. For small organizations with less than 30 members, they can never achieve Innovative Behavior without Organizational Trust. Conclusively it is acknowledged that Organizational Trust is the most important prior condition for innovation and long-term survival of SME ventures.
