This study estimated the impacts of the building permit area change on the forest products import quantities in Korea. The first objective of this dissertation is to analyze whether there is any causal relationship between change in the building permit area and changes in the import quantities of forest products in Korea. Assuming that there is any causal relationship, the second objective is to evaluate the dynamics of the impacts of the building permit area change on the forest products import quantities in Korea. The relationship between the building permit area and the import quantity was represented by bivariate vector autoregressive or vector error correction model. Whether there is any causal relationship between change in the building permit area and changes in the import quantities of forest products was analyzed by the causality test of Granger. And the dynamics of the impacts of the building permit area change on the forest products import quantities were evaluated by variance decomposition analysis and impulse response analysis. The import quantity of forest products can be explained by the lagged building permit area variables and the lagged import quantity variables in Korea. Change in the building permit area causes change in the high-density fiberboard import quantity in Korea. In the bivariate model of the high-density fiberboard import quantity, after six months, the building permit area change accounts for about ten percent of variation in the import quantity, and its own change accounts for about ninety percent of variation in the import quantity. On the other hand, the impact of a shock to the building permit area is significant for about six months on the import quantity of high-density fiberboard in Korea. That is, if the building permit area change indeed had an impact on the import quantity of high-density fiberboard in Korea, it was only of a short-term nature.

This paper analyses the interrelationship among wholesale price, trading volumes, import volumes and demand for three agricultural products (cabbage, onions, and garlic) by using the consumer panel and the data from the Korea Rural Economic Institute and the Korea Customs Service with a VAR model. The results are summarized as below. (1) The prices of three agricultural products decrease when trading volumes increase while the price of cabbage and onions decreases when import volumes increase. But the prices of three agricultural products have little effects on trading volumes. (2) The demand of three agricultural products increases when trading volumes increase while the demand of cabbage and onions increases when import volumes increase. (3) when demand of garlic and cabbage increases by 10%, their price increases by 2.5% and 1.3% respectively. And the demand of garlic has positive effects on import volumes of garlic.

환율의 과도한 변동이 무역량을 위축시키는지에 대하여 선진국을 대상으로 그 동안 많은 연구가 있어 왔다. 최근 한국은 1990년 이후 제한하여 오던 환율의 변동허용폭을 폐지함에 따라 환율의 과도한 변동을 경험하고 있다. 본 연구는 한국의 경우 환율의 변동성이 원유수입(原油輸入)에 미치는 효과를 장단기(長短期)로 구분하여 Johansen에 의하여 개발된 공적분기법으로 분석하였다. 분석결과에 의하면 단기에 있어서 환율의 변동성은 원유수입을 감소시키나 장기에는 원유수입에 큰 영향을 주지 않는 것으로 나타났다. 이는 단기에는 원유(原油)의 비축물량이 존재하여 가격의 불확실성이 원유수입을 감소시키나, 장기적으로는 원유수입이 비경쟁적 수입이고 수입기업이 환위험을 감소시키는 기법등을 사용한 결과로 환율의 변동성이 원유수입에 큰 영향을 주지 않았다고 할 수 있다.

최근 쇠고기 저가방출이 소값 안정에 기여했다고 생각할지도 모르나, 양돈.낙농육우 등 축산업계가 흔들리고 있다. 우리 축산업계에서는 기회있을 때마다 축산자재(사료 등)에 대한 부가세 영세를 적용을 건의해 왔다. 결국 쇠고기 수입량의 증가, 축산기자재에 대한 부가세 영세율 적용불가, 향락산업의 번창은 그결과가 어떻게 오리라는 것은 이번 일본의 참의원선거를 통해서 우리가 확인한 셈이다.

"흑염소는 대부분 소규모로 사육되고 있어 산업적인 비중이 낮아 축산관련 분야에서 별 관심 없이 여겨왔던 축종이었으나 `80년대 이후 건강식품에 대한 소비가 증가됨에 따라 농가 수입원으로 정착되기 시작하여 사육규모도 서서히 증가하고 있는 단계에 이르고 있다. 그러나 근래 경기침체로 인한 소비위축과 사료값 상승, 염소고기 수입량 증가 등으로 염소산업이 전반적으로 침체되어 있다. 금년에는 염소고기(육용)의 소비량이 가장 많은 시기인 봄부터"

This paper is designed to investigate the dynamic structure of optimal tariff imposed by the oil importing country from OPEC when OPEC increases the oil reserves through exploration and development. For this purpose, we used a Stckelberg differential game modeling approach, and tried to analyze two cases such that the one is the extraction cost is dependent on the oil reserves and the other is the extraction cost is independent of it. On the basis of this analysis, we propose that the importing contry has to impose dynamically inconsistent tariffs if the extraction cost is dependent on the oil reserves. Otherwise, she should impose dynamically consistent tariffs announced at initial time. In addition, we found that whether or not the exporting country uses some portion of oil produced for domestic consumption does not affect our policy proposition stated above.

The data used in the study were taken from the national dairy genetic evaluation of bulls from 1986 up to 2001. It was conducted to compare the phenotypic performance and genetic merits in terms of production traits, linear traits and selection indexes of four types of dairy semen (TypeⅠ:semen from Korean proven bull, Type Ⅱ:semen from proven bull imported by National Agricultural Cooperative Federation(NACF), Type Ⅲ:semen imported from USA, Type Ⅳ:semen imported from Canada) used in Korea. The result of national dairy genetic evaluation was used to compare genetic merits. Type Ⅲ was superior in the phenotypic performance of milk yield, milk fat and milk protein and was significantly different from Type Ⅰ. Types of semen were not significantly different in fat when semen from bull born after 1991 were compared. Likewise, types of semen were not significantly different in the genetic merit for milk yield, milk fat, milk protein and milk protein %. Moreso, for profit index (MFP) and Korean type production index (KTPI) it was not statistically different. However type Ⅰ was superior in milk fat % and was significantly different from other types. Type Ⅳ was superior in Final Score of conformation test (FS) and Udder Composite Index (UDC) and significantly different from Type Ⅰ. When semen from bull born after 1991 were compared, types of semen were not significantly different in milk yield and milk protein, although type I was superior in milk fat, milk fat %, milk protein % and MFP and was significantly different from others. Moreover type Ⅲ and type Ⅳ was superior in UDC and were significantly different from others.
