The research objective examines the effect of corporate governance on capital structure and its effect on liquidity policy and corporate performance. It tests the effect of capital structure and liquidity policy on corporate governance. It also examines the effect of liquidity policy on capital structure and the effect of capital structure on liquidity policy. The study population is all manufacturing companies that went public on the Indonesia Stock Exchange in the period 2010-2019. The research population is 182 manufacturing companies. The Judgment Sampling was used and 109 companies meet the research criteria. The study used panel data for ten years so that the amount of data observed was 1090 observations. The analysis tool uses Warp Partial Least Square (WarpPLS). The results showed that corporate governance had a significant positive effect on capital structure, but corporate governance had a significant adverse effect on liquidity policy, and corporate governance had a significant positive effect on corporate performance. Furthermore, capital structure has a significant negative effect on corporate performance, but liquidity policy has no significant effect on corporate performance. Capital structure and liquidity policy are proven to be reciprocally significant positive correlations for manufacturing companies in Indonesia.

Background: Bankrupted households have recently been increased due to excessive medical expenditure in Korea. They have not been protected from economic risk when household's member has severe diseases that need a lot of money for treatment. Purpose of this study examines policy effect by comparing unmet needs' change of policy object households and non-object groups. Methods: We used Korea Health panel 2nd 4th data collected by Korea Institute for Health and Social Affairs and National Health Insurance Service. Analysis subjects were 381 households (pre-policy) and 393 households (post-policy) that had cancer and cardiovascular and cerebrovascular diseases. Since it was major concern that estimates benefit strengthening policy started by certain time, we setup comparing households which had diabetes, hypertension disease. Comparison subjects were 393,247 households, respectively and we evaluated policy effect using difference in difference (DID) model. Results: Although unmet needs of policy object households were higher than non-object groups, policy execution variable affected negative direction. But interaction-term which shows pure effect of policy was not statistically significant. We utilized multi-DID model to examine factors affecting unmet needs causes. Copayment assistance policy did not significantly affect households that responded to 'economic reason,' and 'no have time to visit' for unmet needs causes. Conclusion: The second copayment assistance policy did not significantly give positive effect to beneficiary households than non-beneficiary groups. When we consider that primary purpose of public insurance guarantee high medical expenditure occurred by unexpected events, it needs to deliberate on switch of benefit strengthening policy that can assist vulnerable people. Also, we suggest that government forward a policy covering non-reimbursable medical expenses as well as switch of benefit strengthening direction because benefit policy do not affect non-covered medical cost which accounts for quarter of total health expenditure.

According to the system dynamics model of this study, if there is a significant network effect on vehicle operating costs, it is difficult to achieve the shift to AFV even in the long term without a policy intervention because the car market is locked in to the current structure. Network effect can be caused by an increasing return to scale in fuel supply sector as well as in maintenance service sector. It is also related to the fact that the reliability and awareness of consumers on new products increases with the growth of the market share of the new products. There are several possible policy options to break the 'locked in' structure of car market, such as subsidy on vehicle price (capital cost), subsidy on fuel (operating cost) and niche management policy. Combined policy options would be more effective than relying on a single policy option to increase the market share of AFV.

Although there have been studies regarding the separating policy of dispensary and medical practice, little study have provided a concrete empirical evidence to what extent the policy objectives are achieved. In this paper, we try to provide empirical evidence whether the policy separating dispensary from medical practice achieved the policy objectives, which representatively are reducing the mis-use or over-use of anti-biotic prescriptions and medicines, and decreasing the government spending for the cost of pharmaceutical support. By comparing the average of the rate of change of the number of medicines prescribed, the rate of anti-biotics prescribed, and the government spending for the cost of pharmaceutical support between the areas where the separation policy was implemented and the exceptional areas, we concluded that it is difficult to conclude that the policy separating dispensary and medical practice achieved its policy objects, as it first announced to achieve in the introduction of the policy in 2000. However, the limitation of this study is that the data, that can thoroughly analyze the effect of separating policy of dispensary from medical practice, cannot be collected as expected. Hence, we could not use a parsimonious empirical model to evaluate the effect of the policy introduced in 2000. Rather we used a simple statistical method to extract enough empirical evidence fro m the data available. In the near future, we would expect to see more research that analyze the exact effect of policy separating dispensary and medical practice with concrete empirical model using more sophisticated dataset.

In this paper we analyze the effect of the credit period on inventory policy under trade credit with ordering cost including a fixed cost and freight cost, where the freight cost has a quantity discount. For marketing purposes, some supplier offers credit period to his buyer to stimulate the demand for the product he produces. The delay in payments during the credit period has the effect of reducing the buyer's capital opportunity cost. It is also assumed that the buyer pays the freight cost for the order and hence, the ordering cost consists of a fixed ordering cost and a variable freight cost which depends on the order quantity. As a result, the possibilities of trade credit and discounts on freight costs are expected to play an important role in the buyer's inventory policy. Based on the economic order quantity inventory model, we analyze how the buyer can determine the optimal inventory policy and we examine the effect of the length of credit period on the buyer's inventory policy.

This paper tries to identify the effect of reducing PM2.5 concentration of the First Seasonal Management Policy implemented by Korean government by using statistical method. In particular, this paper tests the hypothesis that this policy effect may differ by region (west-coast, south-coast, and east-coast). To this end, this paper analyzed only pure policy effects by removing temporal abnormalities such as COVID-19, warm winter temperature during the policy implementation period (December 2019 to March 2020) by using the difference-in-difference method (DID). As a result of the analysis, this policy had the effect of reducing PM2.5, but the effect is not homogenous by region. In particular, PM2.5 reducing effect is the largest in west-coast region and south-coast region folllows, but its effect is not statistically significant in the east-cost region. In conclusion, this paper drew implications that the current Seasonal mamangement policy which is implemented regardless of the regional difference needs to be changed.

In this paper, an alternative inventory policy that trades off the bullwhip effect at an upstream facility with cost minimization at a current facility, with the goal of reducing system wide total expected inventory costs, when external demand distributjon is autocorrelated, is considered. The alternative inventory policy has a form that is somewhere between one that completely neglects the autocorrleation and one that actively utilizes the autocorrelation. For this purpose, a mathematical model that allows us to evaluate system wide total expected inventory costs for a periodic review system is developed. This model enables us to identify an optimal inventory policy at a current facility that minimizes system wide total expected inventory costs by the best tradeoff of the bullwhip effect at an upstream facility with cost minimization at a current facility. From numerical experiments, it has been found that (i) when the autocorrelation is negative, the optimal policy is one that actively utilizes the autocorrelation, (ii) when the autocorrelation is small and positive, the optimal policy is one that neglects the autocorrelation, and (iii) when the autocorrelation is large and positive, the optimal policy is somewhere between one that actively utilizes the autocorrelation and one that neglect the autocorrelation.

Since the foreign currency crisis, Korean economy has suffered recession and the government launches residence and real estate policy in order to increase the demand and trade of real estate and to help the economy revitalization. 1 As a result, the rate of economy growth is shown the high increase with the figure of 10.9% in 1999 and 8.8% in 2000. However, it brings overheating market as a negative effect. Although, the government established the policy for the control of speculation, the policy causes instability of economy. This study is to analyze the effect between the residence policy and the housing cost since the foreign currency crisis through housing sale price estimation and housing lease price estimation and is to apply the basis data of the next residence policy.

Aviation/tourism industry has a unique characteristic of high inter-dependance between customer and service-provider. It is the mental condition of service-provider that could influence on the attitude of the service-provider. Thus, it is important to manage the mental condition of the service employees to enhance a company's financial performance. This paper tries to analyze the combined model of both policy acceptance and service profit chain(SPC) models. First, service policy acceptance model tells how the service policy acceptance, which consists of policy compliance, trust, participation and policy failure, would influence on SPC model. According to empirical research, it was found that both the employees' policy compliance and the policy trust have a positive significant impact on their participation on service policy. In the policy acceptance model, the employee's voluntary participation based on their trust and compliance of the policy was proven to have a positive effect on increasing job satisfaction and customer orientation. Regarding SPC model, their participation in the policy had the strongest impact among variables on customer orientation. Such results implies the employees' participation on the policy could become the starting point to enhance the customer value.
