Given the constraint that the unemployment benefit is not allowed to vary freely over the unemployment duration, this paper examines the optimal UI benefit structure. In particular, identifying the conflicting effects of benefit amount and benefit duration upon incentive and insurance, this paper characterizes the optimal combination of UI benefit amount and duration. Based upon some important factors determining the optimal UI benefit structure that are derived from the model, a set of directions for UI reform in Korea have been proposed.

Recently, urban information system(UIS) has been developed and utilized by local governments in Korea and has become a key means of urban informatization of local governments. When UIS is conducted only for FM oriented internal utilization regardless of its cost-efficiency, however, its cost-benefit structure could be distorted seriously. The study utilizes benefit cost analysis technique and applied the technique to a model case of Chungju UIS selected by National GIS team. Chungju City developed its GIS for the management of roads and urban planning in 1993. At its beginning, the system was an efficient model with relatively strong cost-benefit structure and could produce positive net benefit 10 years' after its construction. When the city began to develop its facility management with the financial assistance from central government in 1998, however, its cost-benefit structure became distorted. As a result, it is delayed for the UIS to produce positive net benefit until the year of 2015. Using benefit cost ratio, discount rate and Mobile GIS, the study also conducts a sensitivity analysis.

This paper studies the macroeconomic effects of an enhancement in unemployment benefits in Korea. In particular, I quantify the welfare effect of two specific policy chances which have been mainly discussed among policymakers in recent years: increasing wage replacement rates by 10%p and extending maximum benefit durations by one month. To this end, I build and calibrate an overlapping generation model which reflects the heterogeneity of the unemployed and the specificity of the unemployment insurance (UI) system in Korea. The quantitative analysis conducted here shows that extending maximum benefit durations by one month improves social welfare, whereas increasing wage replacement rates by 10%p deteriorates social welfare. Extending maximum benefit durations is applied to potentially all the UI recipients, including unemployed workers whose wage before job loss is relatively low and whose marginal utility is relatively high. However, increasing wage replacement rates is applied to only a small number of UI recipients whose wage before job loss is relatively high, while the increase in the UI premium is passed onto all of the employed. This study suggests that given the current UI system and economic environment in Korea, it is more desirable to extend maximum benefit durations rather than to increase wage replacement rates in terms of social welfare.

Given the limitations of UI benefit and self-insurance through precautionary savings, this paper suggests a new scheme of income support for the unemployed, which offers unemployed workers not only UI benefit but also borrowings from their future pension incomes. Allowing individuals to have effective self-insurance through pension- borrowing, this scheme provides them with consumption-smoothing and reduction in risk burden while maintaining search incentives of the unemployed. Simulation study based upon household panel data in Korea suggests that a heavy reliance should be set upon self-insurance through pension-borrowings rather than upon UI benefit, even for the low-income individuals who are subsidized under UI system. This result provides us with insightful implications for a social safety net in (fast-growing) developing countries, where people cannot afford a good amount of UI benefit or of precautionary savings against unemployment although they expect their incomes to be much higher in the future. Indeed, it is consumption-smoothing effect of self-insurance through pension- borrowings, as well as its incentive-maintaining effect, that makes it a promising alternative of social safety net in developing countries.

Using the simulated data set which is based upon the data set merging Economically Active Population Survey(EAPS) and the Supplementary Survey (SS) in 1998-2001, this paper examines the relevance of alternative programs Unemployment Insurance Savings Account (UISA) and Pension-funded Unemployment Benefit (PUB) - to unemployment insurance system in Korea. Estimating the relative size of unemployment benefit and IA balance under a specific type of UISA or PUB by simulation, this paper yields the two main results. First, replacing UI by UISA with the same benefit being maintained would be beneficial in terms of search efficiency in general, although its effectiveness is a little doubtful as for the non-regular workers. Second, the PUB is better than UISA as an alternative to UI, and also works relatively well even for the non-regular workers.

This paper investigates the cyclical behavior of UI benefit take-up rate, the share of unemployed persons who are eligible for job seekers' allowances(JSA) and actually receive them. Using Korea's Employment Insurance DB, it also identifies the factors linked to the decision to take up job seekers' allowances. The results show that the take-up rate is countercyclical and leads both unemployment rate and Coincident Composite Index cyclical component by 6 months and is positively correlated with replacement rate and benefit duration, suggesting that extending benefit duration and raising benefit level can boost benefit claims to increase take-up rates in Korea.

In this paper, the method on calculating benefits of combined heat and power is introduced for standard evaluation in electrical power system. This paper calculates benefits about new national viewpoint and viewpoint of independent power producers and assesses benefits of combined heat and power in Korea and In Seoul national capital area. Benefit costs are composed of avoid cost of centralized generation, line upgrading adjustment, loss adjustment and electrical power trade cost per year in earlier study, in addition trade cost of CO2, construction cost of combined heat and power for accurate calculation. Benefit of combined heat and power is calculated by simulation results of real electrical power system.

Purpose: Based on the Health Belief Model, this study aimed to identify factors influencing on COVID-19 vaccination intention of mothers with elementary school children by examining the relationships between perceived susceptibility, perceived severity, perceived benefit, perceived barrier, cue to action, and perceived self-efficacy. Methods: Mothers with elementary school children were recruited from three elementary schools. An online survey was conducted of 130 mothers in November, 2021. Results: As a result, the factors influencing on vaccination intention were perceived self-efficacy (β=.33), perceived susceptibility (β=.18), perceived benefit (β=.16), and perceived barrier (β=-.17). Conclusion: Based on our findings, there is a need to develop a tailored nursing intervention that enhances perceived self-efficacy, perceived susceptibility and perceived benefit while decreasing perceived barrier in order to improve vaccination intention.

The purpose of this paper is to suggest the implications of volunteering's task design and the volunteer's placement that make the motive-benefit matching from the functional perspective of motivation. For this study, we conducted a multi-regression analysis to examine the impact of the volunteer motivation on task satisfaction and retention will. Results showed that first, volunteers' most important motive for volunteering was social motive, followed by enhancement, value. Secondly, each motive influenced the task satisfaction and retention will of volunteers differentially. The practical implications of these findings were discussed.
