This paper analyzes the demand and supply structure of the market for college professors, and then characterizes the changes in the economic status of them for the last three decades. On the supply side, the number of Korean recipients of doctorate degrees from the U.S. institutions, relative to the number of newly hired professors, has declined dramatically since early 1990s. The relative remuneration of professors, which is found to be closely related to the 'number of students per professor', has also declined steadily. These suggest that the decline in the relative wage of professors has been a driving force for the decline in the relative size of new PhD's in the U.S.

The purpose of this study is to explore the structure of social discourse on aging in Korea by analyzing newspaper articles on aging. The analysis is composed of three steps: first, data collection and preprocessing; second, identifying the latent topics; and third, observing yearly dynamics of topics. In total, 1,472 newspaper articles that included the word "aging" within the title were collected from 10 major newspapers between 2006 and 2019. The underlying topic structure was analyzed using Latent Dirichlet Allocation (LDA), a topic modeling method widely adopted by text mining academics and researchers. Seven latent topics were generated from the LDA model, defined as social issues, death, private insurance, economic growth, national debt, labor market innovation, and income security. The topic loadings demonstrated a clear increase in public interest on topics such as national debt and labor market innovation in recent years. This study concludes that media discourse on aging has shifted towards more productivity and efficiency related issues, requiring older people to be productive citizens. Such subjectivation connotes a decreased role of the government and society by shifting the responsibility to individuals not being able to adapt successfully as productive citizens within the labor market.

We analyze the social welfare effect when a policy-based financial system (PFS) enters a decentralized financial market. Particularly, the PFS in this case supports the interest spread for corporate loans held by firms with heterogeneous bankruptcy decisions under an imperfect information structure. Although support for capital costs through the PFS expands the economy consistently, the optimal level of PFS out of the corporate loan market is estimated to be 8.6% by a simulation model considering social welfare adjusted by the disutility of labor. This result is much lower than the recent level of PFS in the Korean financial sector.

This paper empirically analyzes the behavioral patterns of the labor flows surrounding self-employment. One of the findings is that, while a substantial portion of the labor flows into (and from) the self-employment sector is a movement from (and into) the non-employment, such flows are largely confined to a relatively small group of marginal workers. Still, the share of those marginal workers among the self-employed has declined steadily at least until the outburst of the financial crisis in 1997, evidencing that the job stability has been increased in this sector. On the other hand, the expected duration of self-employment has shown a downward trend up until 1990 but has increased since then. Such a trend reversal is also observed in the proportion of the labor force self-employed, indicating that the former is at least partly responsible for the latter.

Consider an n goods production economy. Assume the equilibrium condition of Sraffa's price system, a balanced growth condition and the goods market clearing conditions. If both equations are given to determine a real wage rate and investment, the economic system is over-determined. It suggests that there exists no long-period equilibrium to satisfy both labor market and goods market conditions. This paper interprets this situation of over-determinacy as a disequilibrium state, and attempts to solve it through disequilibrium dynamics. It constructs a model of accumulation and real wage rates consistent with Lotka-Volterra system, and shows that the overall growth path fluctuates endogenously around a resting point of long-period disequilibrium.

This paper adopts a distributive performance process model of in-work poverty based on labor markets, households, and welfare states and analyzes the 4-11 waves of the Korean Welfare Panel Study during 2008-15. Previous studies on in-work poverty have focused on the definitions and concepts of in-work poverty by analyzing employment and unemployment persistence and repetition dynamics, but rarely paid attention to institutional distributive performance. In this regard, this study preforms a stepwise analysis of labor markets, households, and welfare states as a process of income generation in labor markets, satisfaction of welfare needs and income pooling at households, and deduction of social security contribution and income tax as well as receipt of public transfer income at welfare states. Results of empirical analysis show that in-work poverty had been on increase during 2008-11, followed by a decrease between 2012-15. At labor market stages, full time status had the most prominent impact on in-work poverty process, while status by employment and contract type have generated a huge variation as well. At household stages, household work intensity and number of earners contributed to reduction of in-work poverty, but the relations did not seen to be straightforward. However, welfare state played little role in lifting employees out of in-work poverty. In terms of institutional distributive process, in-work poverty was prevalent in either household-welfare state stage or labor market-household-welfare stage. Non-vulnerable group in terms of in-risk poverty was around 80% of the sample during the period of analysis, the size of which has remained constant.

In general, women's labor force participation follows a M-curve pattern because women's state of economic activity usually changes by their life course stage. This research attentions that the effect of sequence of life course as well as the effects of‘marriage bar’, or‘maternity leave’is very important in understanding women's chaning economic activity status. First, this research hypothesizes that women's four patterns of job career such as‘continuous pattern’,‘discontinuous pattern’,‘non-economic activity pattern’,‘marriage leave pattern’result a significant difference in social and demographic variables. Second, this research analyzes the effect of ordering and timing of life events on women's work transition. This research investigates labor market dynamics to conceptualize labor market behaviors using longitudinal data and sequence analysis and event history analysis. We find that four patterns of job career vary by age, educational attainment, having a certificate or not, their parents’human capital and health status. And we find that the ordering and timing of‘participation in labor market’and‘marriage’determine the pattern of women's work transition.

The purpose of this study was to investigate the contexts in which employed mothers with young children consider leaving the labor force. We used a mixed methods design, which integrates the findings of quantitative and qualitative analyses, to better understand the dynamics underlying employed mothers' intentions to leave the labor force. The participants of both quantitative (N = 324) and qualitative (N = 16) data were married mothers who were employed full-time and had at least one child younger than elementary-school age at the time of data collection. Both the quantitative analysis of logistic regression and the qualitative thematic analysis revealed that the child's age, the husband's income, the utilization of child care by relatives, the mother's job involvement, family-to-work role conflict, and other costs and rewards of participation in the work force were the important contexts where employed mothers considered leaving the labor force. The quantitative analysis uniquely found that being employed at a workplace with flexible work hours were associated with lower odds of considering exit from the labor market. The qualitative analysis highlighted that the decision to leave the labor force or to stay in it is a complicated issue that almost all employed mothers potentially face at some point in their careers. These findings suggest that policy support is warranted to help employed mothers with young children remain in the workforce when they wish to.

This paper identifies the mechanisms governing the industrial location changes in Korea by focusing upon the emergence of the country's large conglomerate business organizations (chaebols). As the country has distinctive industrial organization, production systems, and government-business relations, this study tries to develop an ideal conceptual framework for the analysis of industrial location changes in Korea. It perceives the Korean economy as a system within which 'space-organizing', lage business organizations interact over time with government, smaller firms and multinational corporations at different geographical scales. The usefulness of the model is assessed using a case study of Korea's most representative chaebol, the Samsung Group. This study identifies chaebols as the dominant institutions in Korean society. Their growth and business strategies have been influenced by the Korean Government through its power to allocate capital resources. Regional dynamics of industry and labor, therfore, have been strongly influenced by changes in the location, industrial structure, and production system of chaebols. With econmic power concentrated within a few giant business groups and their major areas of operation restricted, unbalanced regional development has resulted. Dissatisfaction from residents in less-developed areas has pressured the Government to advise chaebols to disperse their production facilities. Most small and medium-sized firms are closely linked to large corporations through subcontracting. By forming hierarchical subcontracting. By forming hierarchical subcontracting systems, chaebols have indirectly exploited scattered, part-time, home-based, female and lower-paid laborers organized by subcontractors. Further, chaebols have expanded their business arena to encompass overseas locations in a bid to overcome the problem of a small domestic market, trade regulations and increased market, trade regulations and increased labor costs. Through their international business networks Korea's local and regional economies are integrated into the world economy. Indeed, the identification of the changing relationships of chaebols with both the Korean Government and smaller firms is the key to explaining the nations's spatial dyanmics of industry and labor.

This research examines the spatial development of rural industrial estates (Nong-gong Jigu) in Chonbuk province and gives insight into the strategies for economic development in the entire region. Selected location factors which are likely to pull new investment into the estates are examined by using questionnaires. Few loction factors except nonlocal factors can be found in explaining why location choices are made. The irrelevance of the analysis based on location factors suggests that an alternative approach should analyze changes in the spatial development of the rural industrial estates. Such an alternative is to understand the dynamics of the spatial organization of production by focusing on characteistics of plant closing in the rural industrial estates. To take into account of the characteristics of plant closing we provide the hypothesized relationships between employment size, organizational structure, inter and intra industrial linkage, characteristics of production processes, and availability of local labor market and the likelihood of closing. A logit model is then made to identify the selected factors which might influence the probability of plant closing. The results from the logit analysis and their implications suggest that the policy should be more concerned with the characteristics of firms, such as size and ownership, as well as of the local labor markets. Given that the Chonbuk region has experienced rapid population decline, together with its poor industrial base, it seems that the success of the policy in the declined rural areas in less certain.
