This study empirically analyzes whether political rent-seeking behavior exits in Korea. The empirical analysis shows that there is a cyclical decline in aggregate revenue immediately following the election year. However, when using other aggregate fiscal variables including aggregate revenue, fiscal balance, tax and public burden ratio, no such cyclical deterioration are found. By sector, the expenditures of the economic affairs show a cyclical increase in the year right after the election. In addition, as the ratio of ruling party senators to total senators is high, the expenditures of the economic affairs tend to increase more and this tendency becomes more stronger right after the presidential election year. Such a result turns out to be consistent even when the expenditure was analyzed separately from the mandatory and discretionary expenditures by sector. This is a testimony to the existence of political rent-seeking behavior in Korea.

It is considered necessary to renewal a considerable number of water supply facilities in Korea because they began to be intensively buried in the period of rapid economic growth. Accordingly, local water providers are required to take measures against this situation, but they have currently been caught in a vicious circle of the lack of budget spent in renewing water supply facilities because county-based small-scale local water supply cannot afford to cover annual expenditures with their revenues from water rates. Therefore, this study developed an optimal renewal planning model capable of achieving a balance of financial revenue and expenditure in local water supply using nonlinear programming and furthermore of minimizing the total cost incurred during the analysis. To this end, this study selected the water supply area located in County Y as a research area to build the financial revenue and expenditure and used Solver function provided by Microsoft Excel to use nonlinear programming. As a result, this study developed an optimal renewal planning model minimizing incurred costs in consideration of 6 items in the financial revenue and expenditure. The optimal renewal plan was modeled according to the available annual budget. As a result, this study proposed SICD, a scenario to minimize total costs from the perspective of water suppliers, and SITS, a scenario to minimize the increase in water rates from the perspective of consumers. It can be said that the method proposed in this study is the core of the optimal financial and renewal plans as a final stage of asset management for water supply facilities. Therefore, it is considered possible for local water providers to use the method proposed in this study according to circumstances for the asset management of water supply facilities.

The care market has a unique characteristic that cannot be understood only by pure consumerism. It is not simply constituted by the relationship between consumers and providers at a uni-dimensional level of consumerism logic; rather, it operates in the tripartite-dimensional relationship between the state, consumers and providers through the design and regulation of policies by the state(Evers 1994). The unit costs of long-term care insurance has a meaning as the signal of state for policy direction. This paper consists three contents. The first, it provides to examine the developing process and method of the unit costs of long-term care and to define the characteristics of the developing method of unit costs of the Korean Long term care Insurance. The second, it tried to evaluate the adequacy, validity, and equity of unit costs of care. The third, it proposed the policy direction and measures focused on state's role as price determinator and regulator of care market in that unit costs of care is very important factors for formation and operating of care market.

The emissions trading system stands as a pivotal climate policy in Korea, incentivizing abatement equivalent to 87% of total emissions (as of 2021). As the system likely has a far-reaching impact, it is crucial to understand how the real economic activity, energy sector, as well as environment would be influenced by its implementation. Employing a macroeconometric model, this paper is the first study analyzing the effects of the Korean emissions trading policy. It interconnects the Korean Standard Industrial Classification (Economy), Energy Balance (Energy), and National Inventory Report (Environment), enhancing its real-world explanatory power. We find that a 50% increase in emission permit price over four years results in a decrease in greenhouse gas emissions (-0.043%) and downward shifts in key macroeconomic variables, including real GDP (-0.058%), private consumption (-0.003%), and investment (-0.301%). The price increase in emission permit is deemed crucial for achieving greenhouse gas reduction targets. To mitigate transition risk associated with price shocks, revenue recycling using auction could ensure the sustainability of the economy. This study confirms the comparative advantage of expanded current transfers expenditure over corporate tax reduction, particularly from an economic growth perspective.
