In the context of $CO_2$ mitigation, how early reduction action taken by individual companies previous to the actual regulated period is implemented at the free allocation process, remains one of the major issues. This article considered efficiency factor as a criterion for the early action. Then the emissions allowance allocated was compared and analyzed with and without the consideration of early action. In the cases of manufacturing sectors of Korea for the period 2001~2009, it is shown that emissions in the all industries fell by their efficiency factors. The amounts of emissions allowance allocated to the all industries except petro-chemistry are increased when EA is counted in the allocation process.

2002년도 전력소비량은 2,785억kW로서 작년보다 $8.0\%$ 증가하였으며, 12월중 소비량은 248억kW($8.2\%$증가)로 월간 최대를 기록하였다. 이처럼 전력수요가 크게 증가한 것은 8, 9월중 많은 강우와 저기온 영향으로 냉방수요 증가가 둔화되었음에도 불구하고, 10월부터 일찍 시작된 한파의 영향으로 난방전력 수요가 크게 증가한 때문으로 판단된다. $\divideontimes$겨울철 난방전력 민감도 조사에 의하면 총난방전력수요는 665만kW이며, 겨울철 기온이 $1^{\circ}C$하락함에 따라 31만kW의 난방전력이 증가하는 것으로 나타났다. 2002년도 용도별 소비량은 주택용이 $11.8\%$의 높은 증가율을 보였는데 이는 심야전력($24.9\%$ 증가)을 비롯한 난방전력의 수요가 증가한 때문이다. 또한 일반용($9.1\%$ 증가) 및 교육용($11.9\%$ 증가)도 건실한 증가율을 나타냈다. 한편, 산업용전력은 반도체, 기계장비 및 자동차업종 등 수출주도형 업종의 소비량은 높았으나, 소비 비중이 높은 화학제품 및 섬유업종의 전력소비 둔화로 평균증가율보다 낮은 $6.4\%$ 증가에 그쳤다. 그러나 전체 전력소비량에서 차지하는 비중은 $54.3\%$(1,512억kW)로 여전히 제일 높았다. 지역별로는 수도권이 1,049억kWh를 소비하여 전체의 $37.7\%$ 부산$\cdot$경남은 532억kWh로서 $19.1\%$를 점유하였다.

So far, the phenomenon of "electrification" has been deepened in Korean industry and especially direct heating energy which accounted for 44.0%(2010) of total energy consumed in Korean manufacturing has been significantly electrified. This paper decomposed electricity consumption for direct heating in Korean manufacturing from 1992 to 2012 using LMDI(Log Mean Divisia Index). This paper includes 4 different factors such as electricity proportion effect, direct heating proportion effect, energy intensity effect and added value effect. And this paper compared the consumption pattern by business type. As results, electricity proportion effect had contributed the most to the increase of electricity consumption for direct heating in Korean manufacturing. And Petrol-Chemical and Iron & Steel had the most electrification of direct heating.

The purpose of this study is to provide the strategic implication of the Korean open air market by examining the factors affecting their competitiveness. I have undertaken empirical research that uses the methodology of a mixture regression modeling, as a way to ascertain the determinants of competitiveness for the Korean open air market. I construct a mixture regression model which uses the proportions of merchandise categories as explanatory variables and the number of visitors as a dependent variable. The analysis of results show that competitive and non-competitive markets have different proportions of merchandise categories. The finding shows that stock farm products and home appliances are major influencers on the number of visitors in neighborhood markets. The finding also presents that stock farm products and processed foods are major influencers on the number of visitors in small & medium-sized city markets.

The export on visual and game industry has grown very rapidly and is expanding its role in economic growth. In contrast, researches on these firms' financial performances in strategic and policy point of view are difficult to be found regarding the export of cultural industry. In this study, we analysis the effects of firms export in cultural industry on their financial performances focusing on game and visual industry. We find that the recent activities of export in game industry have positive effect on firm's growth in game industry. However, we find that the export deteriorate the net profit. On the other hand, we find no significant results in the case of visual game industry. Our results suggest that we need more strategic approaches in exporting goods in contents industry.

We test the hypothesis whether foreign direct investments(hereafter "FDI") can affect the changes of the firm value. In this study, we use a newly developed event study technique, referred to as value-based event study approach(hereafter "VESA"), which is based on the seminal papers of M&M(1958, 1961, 1963) and Lee(2006, 2007). The empirical findings about the effects of FDI's on the intrinsic firm values, which can be measured by intrinsic Q(hereafter "IQ") values of the VESA, are as follows; First, the FDI's are carried out by healthy firms in terms of high IQ's. The IQ values become higher during the post-FDI period than prior to performing FDI's. Second, among the four components of IQ values, the value of assets-in-place, the value of intangible assets, and the value of growth opportunities are all increased during the post-FDI period, except the value of current earnings. Third, the same results are observed in all the samples classified by industry. In sum, thanks to the above findings in this study, we can conclude that the announcements of the FDI's are good and reliable indicators for the firm to signal to the market that the FDI firms are healthy in intrinsic firm values, and also that they have good chances to increase their firm values through the new investments abroad.

우리나라 육계산업은 1960년대 후반기에 외국에서 잘 개량된 전용육계종계를 도입하면서부터 급격히 성장하기 시작하여 비교적 짧은 기간에 육류의 중요생산업종으로 커다란 비중을 차지하게 되었다. 육계산업이 크게 신장함에 따라 관련산업인 종계사업, 부화사업, 사료공업도 크게 발전되는 계기가 되었으며 도계품 중심의 가공업도 발전하게 되었다. (중략)

The main purpose of this paper is to analysis the growth process of new emerging Korean society in Georgia, the USA by investigating changes in the regional distribution of Korean business located in metro Atlanta region. More specifically, it aims to identify the characteristics of spatial distribution of Korean business in metro Atalanta through their locational trends since 1980s. To this end, it has explored the history of Korean migration into Georgia and the locational trends of Korean firms in metro Atlanta by industries. As a result, the main location of Korean firms has expanded into the northeastern regions of Atlanta due to the development of transportation, new regional development, education environment and changes in residential distribution by ethnic. Also, the main Korean business has transformed from retails and restaurant to real estate and finance because of changes in market strategies, institutions and Korean local migration.

This study examines the determinants of proportion of self-employed and their policy implications focusing hotel/restaurant and wholesale/retail sectors in Korea. In this study, we estimate the optimal size of self-employed in Korea using OECD data. Several hypothesis are tested by use of the regression analysis on the panel data of OECD economies during 2000-2007 period. Using the panel data of per capita GNI, unemployment level, income tax burden, we found that the excess supply level of self-employed was about 8.0%~9.5% overall. We also found that the excess supply level of self-employed was 13.7~14.1% for hotel and restaurant sector, and 10.4~11.1% for wholesale and retail sector. This results imply that strategically coordinated programs for noncompetitive sectors are more effectively implemented. Furthermore, more aggressive entry and exit policies are needed to solve the over-supply problem of self-employed in Korea.

This study aims to empirically examine serial entrepreneurship in Korea. Using the ICT startups survey data, I compare serial entrepreneurs with their novice counterparts in terms of business behaviors and performances. I found that serial entrepreneurs are more likely than novice ones to co-found a business with other entrepreneurs, enter a market with relatively large assets and expand their business into overseas market. They tend to put more importance on large-scale production and expansion strategy than first-time entrepreneurs. They are more likely to cooperate with suppliers and customers but less likely with the governments. From their experience of founding and operating businesses, the findings suggest that serial entrepeneurs are more market-oriented and more capable of managing internal human relations and external network of supply chain. Consequently, serial entrepreneurs show stronger early financial performance than novice entrepreneurs especially when they team up to found a business.
