Illegal transactions such as blackmarketing and smuggling allegedly result from too restrictive trade policies. A recent U.S. Senate hearing on the blackmarketing of American goods imported into Korea for the purpose of supporting United States troops and their dependents stationed in Korea concluded with the allegation that Korea's highly restrictive trade practices are responsible for the emergence of the black market. It has also suggested that the removal of such restrictive trade policies would eliminate black market activities. This study addresses the relationship between trade policy and blackmarketing by investigating whether trade liberalization results in the reduction of illegal transactions, and whether the eradication of blackmarketing indeed improves social welfare. When both legally imported goods and illegally exchanged items command the same price, trade liberalization, meaning a decrease in tariff rates or an increase in import quotas, will increase the quantity of legal imports at the expense of illegally transacted goods on the black market. But the price of legally imported goods usually differs from that of illegally sold ones. In this case, a change in the relative prices of these two groups of goods due to a change in trade policy will give rise to income, as well as substitution, effects. Initially, a decrease in the import price due to a decrease in import tax rates or an increase in the allotted quota will reduce illegal transactions, since the decrease in the import price will induce the substitution of legal imports for illegally exchanged, but otherwise, identical goods. On the other hand, the demand for the illegally transacted goods will rise, because of the income effect of the reduced import price. Thus, assuming the positive income effect overwhelms the negative substitution effect, the demand for illegal goods will increase, thwarting the reduction of blackmarketing through trade liberalization. Yet, stepping up the enforcement measures which are geared to preventing blackmarketing itself will drastically reduce the extent of illegal transactions, since it increases the cost of blackmarketing and hence the price of the illegally transacted goods. What this study suggests is that the emergence of the black market in Korea should be attributed more to the excessive supply of duty-free goods imported through U.S. commissaries and exchanges than to the excessive demand for foreign goods. On the other hand, blackmarketing, in most cases, improves economic welfare, since it constitutes an increase in the "actual" amount of imported goods. Suppressing blackmarketing through stepped-up enforcement methods is beneficial only when the substitution effect of the legally transacted goods resulting from the increase in the price of the illegal goods prevails, since the increase in the demand for legal imports must override the decrease in the demand for black market goods as well as the negative income effect.

우리나라의 경우 희귀질환은 국내 유병인구가 2만명 이하로 드물게 나타나는 질환으로 적절한치료 방법과 대체의약품이 개발되지 않은 병을 말한다. 희귀의약품은 대상 환자 수가 적어 연구개발이 어렵고 시장에서 수익성을 기대하기 어려워 제약기업이 쉽게 개발할 동기를 갖기 어렵기 때문에 선진국에서는 희귀의약품의 개발을 촉진하기 위한 제도를 운영하고 있다. 국내에서도 희귀질환자들에게 치료기회를 확대 제공하기 위한 일환으로, 1999년 정부의 적극적인 지원하에 한국희귀의약품센터가 설립되었다. 한국희귀의약품센터는 적용대상이 드물고 대체의약품이 없어 긴급한 도입이 요구되는 의약품 및 희귀질환자 치료용 약품의 구입공급과 제반 정보의 수집 및 제공을 함으로써 국민의 건강증진에 기여하고 있다. 한국희귀의약품센터의 주요 역할은 희귀의약품 및 희귀질환에 대한 최신정보를 수집 분류 데이터베이스화하여 이를 희귀의약품의 수요자 및 공급자 등 필요로 하는 자에게 제공하고 있으며, 특히 적용 대상이 드물고 대체의약품이 없어 긴급하게 도입할 필요가 있는 의약품 및 희귀질환자 치료용 의약품에 대하여 자가 치료용 의약품의 수입추천 안내 및 수입대행, 희귀의약품의 지정추천업무 등을 수행하고 있다. 희귀의약품 지정에 관한 규정은 1998년 4월 16일에 식품의약품 안전처에서 고시하였으며 2013년 2월에 식약처에서 고시 제 2013-8호로 개정하였다. 개정 이유는 지속적인 투자, 연구 개발이 필요한 희귀의 약품의 개발을 활성화하고 지정 한도액을 상향하는 등 희귀의약품 지정제도 개선하고자 하는 것이다. 이번 개정의 주요 내용은 개발 초기부터 '개발단계 희귀의약품' 지정하고 지정 갱신을 위해 별도 생산(수입)실적 보고를 폐지하며, 위탁제조판매업자의 희귀의약품 지정 신청을 가능하게 하고, 유병인구 500명 이하인 경우 지정한도 금액 상향 등이다. 이번 개정을 통해 희귀의약품에 대한 연구 개발이 더욱 확대 될 것으로 기대하며, 앞으로도 희귀질환 환자들에게 원활하게 희귀의약품이 공급되도록 지원 정책이 추진되어야 할 것이다.

Due to greenhouse gas increased by human activities, abnormal climate changes are continuously occurring everywhere in the world and internationally people make efforts to reduce the emission of greenhouse gas. Our country also is making endeavors to realize low carbon society on the foundation of the green growth and for this low carbon consumption pattern settlement through green life is necessary. Therefore for the nationals the offering of the information on greenhouse gas emission that is reduced through the change to low carbon life is required. In this study the objects are beef and wine whose weight of import is high among the beverages and foods consumed in the country and we calculated the food mileage and emission of carbon dioxide of the domestic and foreign product beef and wine and estimated the potential amount that can be reduced when replacing the imported products with domestic products. As the year 2007 being standard if we replace 10% of imported beef with domestic products it is possible to reduce 14,000 tons of carbon dioxide per year and on one day out of a year if we replace imported beef with domestic beef the reduction of 384 tons of carbon dioxide is appeared to be possible. In the same standard year if we replace 10% of imported wine with domestic product we can reduce 1,396 tons and on one day out of a year if we replace imported wine with domestic wine reduction of 38 tons of carbon per year appeared to be possible. Through active promotion and expansion of variety of domestic foods and beverages in the real life of the nationals the consumption pattern of natural low carbon life should be achieved and offering of more systematized greenhouse gas emission DB is thought to be necessary.

This study was conducted to investigate the possibility of replacing imported Timothy hay (TH) with domestic Italian ryegrass silage (IRGS) as a horse feed considering feed quality, nutrient digestibility and feed price. Two experimental diets (TH and IRGS) were fed to six-headed Thoroughbred (body weight, 475.7±33.3kg) of the Korea Racing Authority of Wondang Stud Farm. The 3 head animals were assigned to Control group (TH) and Treatment group (IRGS), respectively. The nutrient digestibility was determined by the total collection method. IRGS is enough for using as a horse feed because its Relative feed value(RFV) was higher than TH and its fermentation quality is suitable for horses. Although no difference was observed in nutrient digestibility, Total digestible nutrients(TDN), and Digestible energy(DE) between Control and Treatment group (p>0.05), the fact that price of IRGS was much lower (53.7~62.4%) than that of TH indicates IRGS has competitive advantage over TH as a horse forage feed. The present study indicates that IRGS can be fully replaced with TH due to its superior economic value even though the similarity of its nutrient digestibility, TDN, and DE to TH.

In this study, it is estimated how many changes of macroeconomic variables are happened under the proposition of import substitution of mining products 1% using macroeconometric input-output model. For this, used macroeconometric input-output model is composed of 141 behavioral equations representing the macroeconomy structure. In general, macroeconometrics models are constructed mainly on the side of the expenditure then it is not easy to estimate the effects of the shocks occurred from industry level. To mitigate that, this study tries to construct a macroeconometric input-output model. Macroeconometrics model which is useful to estimate the effects of macroeconomic shocks, economic policy and more, in this study, is linked with input-output table through the NDI(national disposable income) derived from compensation of employee. And this paper presents the estimation results of import substitution effects of mining products on Korean economy. As a results, GDP is increased 0.00073%, gross labor employed 0.00029%, current balanace 0.00010% and unemployment rate is mitigated 0.00233%.

This paper presents theoretical explanations about the spill-over effects of domestic production of light rail transit and empirically investigates its effects on output, value-added and employment in the Korean economy. We distinguish net gains of domestic production from gross effects that bring about whether localized or imported cars are used. The input-output analysis is employed to fully capture the interaction among various industries involved. The empirical results reveal that net gains of domestic production such as import substitution, improvement of trade balances, and increase in output, value-added and employment are enormous. The cost reduction in construction, E&M systems, cars, management, and tariff and transportation is also significant.

The objectives of this study were to explain market structures of logs imported to Korea from U.S.A., New Zealand. Chile. The demand for imported logs is modeled as a function of output of wood manufacturing in Korea and log prices of competing suppliers. It is hypothesized that the quantity of log impaled in a period is determined by its own and competing prices and the output of wood corresponding manufacturing sector in the current period. Import demand functions of logs imported to Korea from U.S.A., New Zealand and Chile were estimated by SURE(Seemingly Unrelated Regression Equations). Elasticities of amounts of logs imported to Korea from U.S.A., New Zealand and Chile with respect to price of imported log from U.S.A. were -2.88, 1.36 and 3.17, respectively. Elasticities of amounts of logs imported to Korea from U.S.A., New Zealand and Chile with respect to price of imported log from New Zealand were 0.71, -1.65 and 1.44, respectively, Elasticities of amounts of logs imported to Korea from U.S.A., New Zealand and Chile with respect to price of imported log from Chile was -2.88. 1.36 and 3.17.

IMF 이후 시설원예분야에 있어 생에너지, 에너지 절약형, 대체에너지 개발 등의 용어들이 자주 등장하고 하고 있다. 이는 시설원예 난방에너지원의 대부분을 수입에 의존함에 따라 지난 2년간에 걸친 유가의 상승으로 인한 온실경영의 어려움을 단적으로 보여주고 있는 것이라 하겠다. 따라서, 난방연료비의 상승에 대응하여 시설원예의 안정적인 유지 발전과 장기적으로 환경보존이라는 측면에서 난방에너지를 줄이고 대체에너지의 개발 등을 통한 난방비 부담의 감소와 안정된 생산기술을 확립하여야 한다. (중략)

큰 어려움이 예상되었던 2011년 육계산업은 여러 변수들로 인해 예상 밖의 선전을 보였다. 2010년 하반기 종계도태 증가와 맞물려 HPAI로 종계가 일부 매몰처분 되면서 공급과잉이 아닌 공급부족현상이 나타났고, 구제역으로 인한 대체수요, 방사능 유출로 인한 대체수요 등으로 4월까지 산지가격이 폭등했다. 이후 공급량 증가와 수입량 증가가 맞물리면서 가격이 폭락하는 상황이 발생했다. 폭등과 폭락을 경험했던 상반기와 달리 하반기에는 일시적 공급 감소는 있었으나, 꾸준히 공급량이 증가했다. 다사다난했던 2011년 육계산업을 정리하면서 2012년 산업을 전망하고자 한다.
