The objective of this paper is to apply choice experiment methods to estimate non-market value of organic farming and its policy implication. A preliminary survey shows that the attributes of organic farming are reduce environmental pollution, bio-diversity improvements, cultural diversity improvements and maintain local community, reduce green-house gas emissions, energy saving, landscape improvements and tax for organic farming improvement policy. Questionnaire was eight different choice sets presented to each respondent. Implicit values of the attributive levels of organic farming have been calculated into tax money costs per house. This paper compared the six feasible scenarios in terms of willingness to pay per year. This study is expected to contribute to government's organic farming policies and quantitative information related to practice of organic farming.

This empirical study analyzed the policy effect of deregulation in oil product prices. To investigate the effect of deregulation, it is tested whether gasoline prices are determined by market power. Also, the role of government in gasoline tax system is investigated. The empirical analysis has been done by using error correction model. The major findings are as follows. First of all, no significant empirical evidence is found to support that the deregulation affects the determination of gasoline prices. Secondly, the short-term CIF elasticity is estimated to be 0.14. This finding implies that if CIF increases 10%, the gasoline prices increase 1.4%. Finally, the investigation on government role in deregulated market shows that the government has still exercise the power of control through the tax system. For example, the government is seemed to increase the gasoline price more than the increase amount caused by the international oil prices and the exchange rates, because of the intention to achieve the internal revenue increases and lead to gasoline conservation.

It is necessary to draw up many plans to solve problems in the management of groundwater resources in Jeju Island while systematically develop and utilize water resources at an optimal level. It also seems to an evitable option to establish Groundwater Management Areas in Jeju Island. The excess use of groundwater could be discouraged by imposing charges on those licenses. Such policy as allowance trading system do not appear to be because of transaction costs, but could be applied if only were accompanied by complementary method. The methods of using and conserving the limited resources of groundwater should be founded through socially agreeable and appropriate ways. The policy complemented allowance trading system by Pigouian tax could be effective to regulate licenses. This is cutting the numbers of licenses at a constant rate, imposing charges on those who want to continue using licenses, and reimbursing in cash to those who return the licenses.

The Korean government has introduced land policy reform measures recently, in order to stabilize the circulating system of land, without a parent law involving effective land use. The measures aim to change the pattern of land market rather than the pattern of land use. Expecially, the excessive profits tax on land intends to redistribute the owernership of residential land, and to recapture windfall gains on an accrual basis. However, it may incur secondary gains in macro economics and an unintended reduction of urban land supply in the land market. This paper aims to study empirically the impact caused by the excessive profits tax on land, and to promote urban land supply. Ultimately, this paper can be regarded as an interim report on outcome of research projects which aim to propose a method of urban land supply suitable to an advanced society.

We examined the effect of Audit Quality on Accounting Policy by using Book-Tax Difference Variability as the proxy of Accounting Information Quality. We used 2,412 sample data from 2010 to 2014. In short, the result of this study's is as followed. Audit Quality have a negative relevance with Book-Tax Difference Variability. Therefore we can support that the firm has a good Audit Quality shows the better Accounting Information Quality according to this study. This study contributes as follow. we can confirm how does Audit Quality affect Accounting Policy by this study's result. We hope that this study can be helped development of capital market and give a good news to investors on firms that has a good Audit Quality

One of the main problems in Korea's public assistance program, the NBLS (National Basic Livelihood Security), is that the loophole of welfare system is continuously growing. Living wage program is the largest sub-program of the NBLS, and the most important determinant of amount of living wage for each beneficiary is the level of reported income. Therefore, accurate and effective income detection is essential in improving policy effects and furthermore reducing the leakage of wage expenditure as beneficiaries always have an incentive to underreport their income. Since most of them do not pay income tax, the welfare authority should exert an independent effort to effectively detect their income. Considering that living wage is a special kind of income tax of which marginal tax rate is -1, one can apply a classical theory of tax evasion to understand illegal or excessive receipt of living wage caused by income underreporting. Utilizing a classical theory given by Alingham and Sandmo (1972), this paper provides a theoretical analysis of the optimal income reporting of the beneficiary. Then an optimization problem is constructed from the government's viewpoint to derive optimal income detecting device (auditing). This paper proves that cut-off discriminated auditing outperforms random auditing and cut-off auditing which implies if the government assigns a positive audit probability to every reported income less than a certain level and the probability is inversely proportional to the level of reported income, it can minimize underreporting and then gradually reduce the leakage of wage expenditure.

This paper develops a simple theoretical model that is consistent with the empirical evidence of an inverted U-shpated relationship between pollution and per capita income, which is so-called environmental Kuznets curve in this literature. Also, by incorporating the issue of environmental externality into an endogenous growth model, I investigate the circumstances under which growth can be sustained with the optimal control of pollution, and hence the sustainable development can be achieved. In order to study the problem of implementing the social optimum in a market economy, I examine the optimality of three different kinds of environmental policy instruments; pollution tax, pollution-permit trading system (pollution voucher), and direct regulation. This paper shows that the optimum can be implemented with a pollution tax or with a voucher system. Also, it is shown that the socially optimal rate of pollution tax should increase proportionally to the growth rate of consumption.

This study tried to find out the level of national health expenditure and associated factors in the OECD countries and then to derive lessons for Korea's health financing based on the cross-national comparison. As a result, Korea's health expenditure in 2010(7.1% of GDP) accounted for 74.7 percent of the OECD average and ranked as countries to spend less on health. At the same time, the socio-economic indicators such as GDP per capita, elderly population ratio and the total tax revenue to GDP also remained between 72 ~ 82 percent of the OECD average. The public share of health financing(58.2%) was relatively lower than those of other countries. However the health expenditure and the public share have grown 1.9 ~ 2.4 times higher than the OECD average over the past decade. According to the quantitative analysis, countries with relatively high income and elderly population turned out to have high health expenditure. Whereas, an inverse relationship was found between the total health expenditure and the public funding. It was estimated that the value of national health expenditure to GDP decreases 0.083 when the rate of public funding increases 1 percent point. Further, the share of public funding was affected positively by the total tax burden. Based on these findings, this study suggests that the sustainable spending on health and alleviating households' direct burden could be ensured by enhancing the share of public funding along with adjusting the tax burden of the people.

The purpose of this paper is to determine whether the rate schedule of the Korean income tax system embodies the theoretically desirable distribution of the tax burden by income classes. The paper follows the approach of Young (1990) who has estimated the utility function and calculated the magnitude of sacrifice, i.e., the tax burden. The main point of the study is to estimate the utility function. The estimation results may differ if different data sets are used. Therefore, this paper employs the effective as well as the nominal tax rate schedule. The findings derived in this paper are 1) that the effective rate schedule is more appropriate in estimating the utility function; 2) that the middle class has born the relatively heavier burden over time; 3) that the current income tax credit scheme curtails the tax burden on the middle class while intensifying the tax burden of the lower and upper income classes; 4) that reducing the amount of deduction moves the distribution of tax burdens by income classes closer to the theoretically desirable model; 5) that the rate schedule of the Korean income tax system, particularly in 1991, did not conform to the desired model as did the tax systems of developed countries such as the United States, Italy, Japan, and Germany.
