가금산업은 국민소득 증가와 식생활의 서구화로 생산액과 소비량이 증가하여 우리 농업에서 매우 중요한 위치를 차지하고 있다. 그러나 세계 각지에서 나타난 고병원성 조류인플루엔자로 인하여 많은 경제적 피해가 발생하고 있으며, 질병의 인체감염으로 인간의 소중한 생명도 위협을 받고 있다. 우리나라의 경우도 예외가 아니어서 그동안 모두 3차례에 걸쳐 고병원성 조류인플루엔자가 발생하여 많은 피해를 입었다. 고병원성 조류인플루엔자의 발생으로 인한 경제적 피해는 가금생산농가에만 국한되는 것이 아니다. 질병 발생으로 인한 경제적 피해는 생산농가와 직간접적으로 연관된 사료업체, 부화업체, 가공업체, 유통업체, 외식업체, 및 기타 관련 산업에서 골고루 발생하며, 손실보전을 위한 정부의 재정지출 증가로도 이어진다. 이번 연구에서는 고병원성 조류인플루엔자(HPAI) 발생이 미치는 경제적 영향을 계측하고 이와 관련하여 현행 질병 방역체계의 개선 방향을 도출하였다. 근래 들어 고병원성 조류인플루엔자의 연중 발생 가능성이 우려되기 때문에 질병예방과 확산방지를 위한 방역체계의 검토에서 개선 방안에 이르기까지 포괄적으로 다루었다.

금융정책(金融政策)과 자본시장(資本市場)의 증권가격(證券價格)과의 동태적(動態的) 관련성(關聯性)을 실증적으로 분석한 결과, 동태적(動態的) 구조면(構造面)에서 볼 때 특히 주식시장은 화폐에 대하여 시차를 갖는 반면, 장기채시장과 단기무위험시장에서는 시차를 갖지 않음이 발견되었다. 그리고 증권가격형성 메카니즘을 살펴본 결과, 화폐(貨幣)의 증가(增加)는 부(富)의 효과(效果)로 이어지고 그 결과 주가의 상승이 초래된다. 다른 한편으로 화폐의 증가가 대체효과를 반드시 유발시키지는 않으며, 그 이유로는 투자자들이 장기채를 선호함으로써 가격의 상승을 불러일으키는 반면 무위험자산의 경우 가격의 변동은 일어나지 않았기 때문이다. 끝으로, 가격효과(價格效果)의 존속은 비교적 단기로 끝남이 확인되었다. 증권시장(證券市場)의 장기적(長期的) 구조(構造)를 파악하기 위하여 공적분(共積分) 검정(檢定)을 실시하였다. 단위근(單位根) 검정(檢定)에 의하여 우리나라의 금융시계열은 단위근이 존재한다는 사실이 입증되었다. 따라서 금융시계열이 비정상적(非定常的) 확률과정(確率過程)을 따르고 있다. 공적분(共積分) 검정(檢定)에 의하여 화폐의 실질대수 유통속도와 실질주가, 장단기수익비율, 화폐차등수익률과 소득변화율 사이에는 차분후에 장기적 정상균형관계가 형성되고 있음이 발견되었다. 통화정책과 주가는 장기의 동태적 구조 측면에서 파악할 때 장기정상관계를 유지하고 있다. 그리고 주가는 시차(時差)가 0인 동시적(同時的) 통화정책(通貨政策)과 제1계 시차통화정책과 소득에 의하여 결정되고 있다. 다른 금융시계열은 주가결정에 영향을 미치고 있지 못한 실정이다. 주가의 상승은 부(富)의 효과(效果)와 대체효과(代替效果)를 유발하고 있다. 따라서 통화당국은 이점을 고려하여 화폐정책(貨幣政策)을 수립하여야 한다. 그리고 통화량은 주가의 가격형성에 양(陽)의 효과(效果)를 형성하고 있다. 따라서 화폐의 공급량의 증가는 명목주가(名目株價)의 상승을 유발하고 이에 따라 부(富)의 효과(效果)와 대체효과(代替效果)가 발생한다. 이와 같은 현상의 발견은 정부당국의 통화정책과 자본시장정책에 중요한 의의를 갖고 있다고 하겠다. 주가형성(株價形成)에 대한 통화정책의 효과는 당기 뿐만 아니라 차기에도 이어지고 화폐량과 소득이 주가의 결정에 영향을 미치고 있으며 다른 금융변수(金融變數)들은 영향을 미치지 않고 있다. 그러나 실질화폐잔고와 실질주가 장단기수익비율 화폐차등수익률과 소득변화률과는 장기적(長期的) 정상적(定常的) 균형관계(均衡關係)를 형성하고 있다. 따라서 장기적 관점에서 증권시장은 경제성장을 위한 통화정책과 각 분야의 균형적 성장을 유발할 수 있는 재정정책(財政政策)이 요청되고 있다. 위의 논의에서 유추할 수 있는 것은 화폐의 영향을 완화시키기 위하여 option시장의 개발과 농산물, 광물, 기타 실물 및 금융에 대한 선물시장의 개설이 요청된다. 이와 같은 시장을 통하여 통화 정책이 증권시장에 미치는 과도한 효과를 축소시켜 합리적이고 건전한 증권시장(證券市場)의 발전(發展)과 금융시장(金融市場)의 원활한 발전이 이룩될 수 있을 것이다. 자본시장이론(資本市場理論)에서는 화폐는 무시하고 실물적인 관점에서 증권가격의 결정을 연구하거나 위험분석에 주안점이 주어져 왔었다. 본 연구를 통하여 통화정책의 결과가 자본시장에 직접적으로 영향을 미치고 있음을 확인하였다. 통화금융정책과 주가의 유기적 관계를 확인한 본 논문의 결과를 정책당국이 참고하여 통화금융정책(通貨金融政策) 효율성(效率性)을 극대화(極大化)할 수 있을 것으로 본다.

The purpose of this paper is to estimate the environmental performance of 29 Chinese provinces by adopting the advanced measurements, integrated pollution intensity index, IPI, which can be computed using Data Envelopment Analysis(DEA) techniques. This index has the advantage of accounting for multiple resources used, good outputs produced and pollutants emitted simultaneously. The result obtained using the methodology shows the obvious evidence that provinces located around eastern area of China take relatively low levels and these phenomenons have been clearly observed throughout the sample period 1998~2007. The estimated index can be interpreted that the environmental burden in China has been steadily decreased as economic growth. This paper also tries to figure out the relationship among IPI, income levels, economic structures, the level of environmental regulations and FDI inflow. The estimated relationship between IPI and income per capita predicts improving environmental performance with increasing income levels. This explains the improvement in IPI which is simultaneously observed with income increases. According to the 'pollution haven hypothesis', many researches have been concerned the possibility that a large amount of foreign capital has been invested in China to avoid the strict environmental standards in advanced countries. However, the estimated coefficients in all model specifications take negative sign with IPI and highly statistical significant. This is a indication that there are positive impacts of foreign investments on IPI by adopting clean and high technologies from advanced countries.

This article firstly reviewed Permanent Established(PE) concept of OECD and UN model tax treaty and compared it with that of Korean Corporate Income Tax Law(CITL). The various factors regarding profit like ways of deciding the local source profit, scope and calculation method which will be imputed to PE were also reviewed. Based on above, standard PE judgement basis and calculation method of local source profit were also studied by using actual cases in foreign corporation which performs plant construction & sales in Korea. Accordingly to properly solve the conflict regarding international tax and to protect the tax authority against the foreign corporation in Korea, by standing on equality, I now propose followings for the better concept of PE in Korea. Firstly, the article that a building site or construction or installation project constitutes a PE only if it lasts more than 6 months should be modified to reflect OECD model convention's criteria of 12 months. Second, the scope of 'subordinate attorney' which is regarded as PE under CITL is now including 'holding-delivery attorney', 'order attorney', and 'assurance attorney' as well as 'contract attorney'. This is overly limit the activities of foreign corporation. It had better be loosened only to include 'contract attorney' as OECD provisions. Third, the CITL limits the cases of preparatory and/or auxiliary place which is not regarded as PE, thus limit the foreign corporations' business by expanding the concept of PE. This had better be eased. Fourth, in deciding the amount of local source profits, the CITL stipulates to split the profits by the relevant contribution of transaction parties through 'profit split method'. To solve the conflict, the ways of profit split must be better clarified through providing object and detailed standard and basis.

A household survey was conducted to determine the utilization rate of medical facilities and to identify the factors related with the utilization in the South District of Taegu from July 3 to July 15, 1988. Study population included 1,723 family members of 431 households which were selected by one-stage simple cluster random sampling. Well trained medical college students interviewed mainly housewives with a structurized questionnaire. Morbidity rate of acute illness during the 2-week period was 101 per 1,000 persons and it was highest in the age group of 9 years below. The rate for chronic illness was 77 per 1,000 persons, increasing with age, low income and medicaid benefit. During the 2-week period, 689 of 1,000 persons utilized the medical facilities. Of the facilities, most number, 294, used hospital and clinic, and the order ran as pharmacy, health center, and herb medical clinic. The utilization rate was higher in the female, 70-year and older group, medicaid group, the lowest income class and self-employed group than other groups. The average number of visits among users of medical facilities during the 2-week period was 3.25. those who visited medical facilities most frequently were females, the 70-year and older group, the lowest income class and blue collar worker group. During one-year period, admission rate of 1,000 persons was 27.6 and that of female was 38.9, higher than that of male. the eldest group had the highest admission rate. Admission rate of medical insurance beneficiaries was twice or higher than non-beneficiaries. The higher the family monthly income, the more frequently they admitted. During one-year period, average admission days of the persons hospitalized were 22.5 days and males were hospitalized longer than females. The groups which were hospitalized longest were those between the ages of 40 and 49, medical insurance beneficiaries, the lowest income group and unemployed group. During one-year period, average admission days of 1,000 persons were 560 days and those of female were 661 days, more than those of male. The guoups which had the longest admission days were those above 70 years of age, the lowest income and unemployed groups. The medical insurance beneficiaries were three times or longer than non-beneficiaries. In logistic regression analysis of utilization of physician significant independent variables were the 9-year and younger group(+), the 70-year and older group(+), acute illness episode(+), chronic illness episode(+), medical insurance beneficiary(+) and white collar workers(-). Acute and chronic illness episode(+), and medical insurance for government employees and private school teacher(-) were significant variables in analysis of utilization of pharmacy. In multiple regression analysis of the number of physician visits, siginificant variables were acute illnes episode(+), chronic illness episode(+), industrial, occupational and regional medical insurance beneficiary(+), white collar workers(-). Acute and chronic illness episode(+), and medical insurance beneficiary(-) were significant variables in analysis of the number of pharmacy visits. In logistic regression analysis of admission event, significant independent variables were the 9-year and younger group(+), the 70-year and older group(+) , chronic illness episode(+), and medical insurance beneficiary(+).

This study analyzed the effects of housing wealth on the balance accounts of elderly households with an age of over 60 facing the asset decumulation period, capitalizing upon an ordered logit model for the 2011 household finance survey data. Out of some variables representing personal and social characteristics, the age and waged worker variables had a positive effect, but the number of household, low education level, living in the apartment and capital region variables negatively affected the balance accounts of elderly households. Some variables reflecting economic wealth and financial strategies such as the attitude of risk-taking, ordinary income and the ratio of financial assets had a positive impact, but other variables such as DSR did a negative one on the balance accounts of the elderly households. The ownership of housing wealth variable positively, but the ratio of housing assets variable negatively affected the balance accounts of the elderly households, which could be derived from the duality of housing as both consumption goods and assets. However, the ownership of other real estates and the ratio of them in the total assets variables had a negative impact on the balance accounts of the elderly households. Furthermore, since the financial asset-debt ratio worsened the balance accounts of the elderly households with both housing and other real estates, it is implied that the purchase of real estates with excessive bank loans could make them dangerous.

The aim of this study is to review the improvement method of Korea capital gains tax according to the alienation of the real estate, and to suggest an improvement plan. The study has been carried out by reviewing the related literatures. Capital gains tax could be calculated either using the actual price of sale or the standard prices. Korea capital gains tax has been revised many times since 1975 when it was first enacted. Initially the actual price of sale was the default rule and the standard prices was allowed only exceptionally if the actual price of sale could not be detected. The actual price of sale rather than the standard prices should be used for determining the capital gains tax on the transfer. By doing so, the desired principles of taxation such as "principle of taxation on tax paying ability". In conclusion, the present capital gains tax of Korea should be improved in many aspects in order to promote income redistribution function and efficient allocation of resources.

This study examines structures and characteristics of movie consumption media. Using survey data, this research focused on combinations of movie platforms including theater, video, DVD, terrestrial television, cable television and the Internet. The results indicated that there were forty eight combinations in accessing theatrical movies. The market share of theaters was approximately 33.5%. However, this has increased to 64.50% in case of integrating other movie consumption media. The results of Chi-Square analysis showed that although the older movie-goers prefer to theaters, the youngers like to access other movie media. In addition, many movie-goers tended to replicate their viewing at the theater.

The traditional trip-based modeling approach has assumed that a trip is generated for a purpose. However, the approach has not considered trips as a set of connected trips nor has it considered trip chaining. The purpose of this study is to identify general characteristics of trip chaining, and to explore relationships between trip purposes and trip chains using multivariate regression models. The data for this study come from the 2006 Seoul household travel diary survey. It is found that simple trip chains are dominant phenomena, and socio-economic characteristics such as occupation, income, age, and gender are closely related to types of trip chains. People aged less than 20, females, or high-income people are more likely to have a higher number of home-based trip chains. In addition, commute and school trips for workers and students respectively tend to be strongly associated with simple trip chains, while shopping and leisure trips for housewives tend to be related to simple trip chains.
