본 연구는 최근 우리나라 시장에서 의결권이 없는 우선주 가격이 의결권이 있는 보통주 가격보다 높게 형성된 이상 현상의 원인을 분석하였다. 1990년부터 2003년까지 우선주를 발행한 기업의 보통주와 우선주를 비교 분석한 결과, 우선주 시장은 14년간 지속적으로 규모가 축소되고 유동성이 하락하였음을 알 수 있었다. 우선주 가격이 보통주 가격보다 높게 형성된 종목은 외환위기이후인 1998년부터 급증하여 전체 우선주 발행종목의 40%까지 이르게 되었다. 이들 우선주는 대부분 경영실적이 악화된 기업에 해당하며, 발행물량이 극히 소규모이고 외국인 투자자가 외면하는 우선주들로서 단기간에 매우 높은 빈도의 거래가 이루어 진 경우가 많다. 즉, 소수의 투자자에 의해 쉽게 가격이 왜곡된 후, 거래량이 없이 기세로서 가격이 표시되어 유지된 경우가 많다고 추론할 수 있다. 이들 우선주는 원래에는 전환사채로 발행되었다가, 훗날 우선주로 전환된 경우가 대부분이었다.

본 논문은 최근 미국에서 성행되고 있는 기업합병(企業合倂)과 기업비공개화(企業非公開化)와 같은 기업재구성(企業再構成)의 동기를 대리인(代理人) 문제(間題)의 관점에서 설명하는데 그 목적이 있다. 기업합병의 경우, 취득기업의 내부자지분율(內部者持分率)이 높을수록 주주의 부(富)는 합병을 통해 증가하는 반면 내부자지분율이 낮은 기업은 합병을 통해 기존 주주의 부(富)는 오히려 감소한다. 이러한 현상은 소유경영자지분(所有經營者持分)이 낮을 수록 대리인비용이 크게 발생한다는 이론과 일관성(一貫性)이 있음을 알 수 있다. 또한 피취득기업의 주식가격은 합병정보가 공시 되기 이전 몇개월동안 크게 하락하였으나 합병 공시와 동시에 크게 상승하는 현상을 나타낸다. 그 이유는 대리인문제(代理人問題)로 설명 할 수 있다. 피취득기업의 경영자는 기업자원을 비효율적으로 운용할 것(지분(持分)의 대리인비용(代理人費用))이므로 합병공시전 주가는 하락하지만, 합병공시후에는 이러한 대리인문제가 개선될 것이므로 주가가 상승한다는 것이다. 따라서 합병의 경우, 취득기업과 비취득기업 모두 대리인문제(代理人問題)와 관련을 갖는다. 또한 1980년 이후 공개기업(公開企業)의 경영자가 자기회사 주식을 매입한 후 비공개기업(非公開企業으)로 환원(還元)다하는 현상이 유행하고 있다. 비공개기업으로 환원한 기업의 경영자는 창의적 기업활동을 통하여 기업가치를 증대시킨 후 다시 발행시장에서 신주를 발행하여 상당한 이익을 얻고 있다. 이는 공개기업으로 존속하는 경우 낮은 내부자지분율로 인해 대리인문제가 발생하므로 비공개 기업으로 전환함으로써 대리인 비용을 자기주식 취득을 통해 절감시킬 수 있는 증거로 간주된다.

Since convertible debt has both characteristics of stocks and bonds, its issuance can be related to both interests of stockholders and bondholders. Nevertheless, the existing studies focused mainly on the wealth effect on stockholders. In this paper we revisit the hypotheses on the issue of convertible debt especially from the viewpoint of a firm's growth, by making an additional investigation into bondholders' wealth effects. We find that stockholders' wealth increases with bondholders' wealth in the firm whose book-to-market ratio is low and thus is considered a growth firm. This finding seems consistent with the hypothesis in which the issue of convertible debt mitigates the agency cost of debt in the high-growth firm.

올해들어 원유가격 및 국제금리의 하락과 수출호조에 힘입어 경상수지가 큰 폭으로 개선됨으로써 종전에 거액의 통화를 환수해 온 해외부문이 금년에는 통화철조부문으로 전환될 전망이며, 앞으로 해외부문에서의 통화증발압력이 가중될 것으로 예상됨에 따라 통화당국은 지난 7월중 무역금융 융자단가를 인하하고, 통자안정증권발행을 확대하는 등 금융면에서 통화환수노력을 경주하는 한편, 외환부문에서도 단기자본도입억제를 위하여 연지급수입기간을 단축한 바 있다. 이에 이어 지난 8월 21일에는 최근증가추세에 있는 외자대출을 억제하기 휘하여 융자대상 및 융자기간의 축소와 함께 융자비율을 인하하였으면 연지급수입대상품목을 축소하였다. 또한 외국은행 국내지점의 양도성예금증서(CD)업무 취급허용과 함께 외국은행 국내지점 스와프 한도를 축소하고 외국환은행의 수입보증금 징수대상을 기한부수입에도 확대 적용하는 등 일련의 외환부문 통화대책을 추가적으로 실시하였다.

This study is designed to see whether overpriced IPO is caused from firm's earnings management, and how effects this to IPO firm's long-term performance. To examine addressed above, we take a look into how firm's earning quality listing on Korea Exchange in 2007 through 2016 is related with long-term stock performance post IPO. Especially, we measure how associated the disparate ratio between offer price and fair price with earnings quality and long-term performance. To examine these three factors, 'three-step mediated regression analysis method' is used. Earnings quality's calculated by discretionary accruals. Disparate ratio is calculated with offer price and estimating share price's rate measured by applying relative valuation model. To sum up, it is as follows. At first, as earnings quality gets high, the disparate ratio between offer price and fair price gets reduced. Secondly, as earnings quality gets high, firm's long term stock performance follows high. At last, as the disparate ratio between offer price and fair price gets increased, firm's long-term stock performance gets decreased. Moreover, mediation effect of the disparate ratio between offer price and fair price is partially found. Thus, it addresses that raised earnings revision before listing is resulted in overpricing of the IPO, and it also leads to poor long term stock performance. This study contributes that empirical analysis is applied to examine long-term under performance using disparate ratio between offer price and fair price. Moreover, this is useful not only to alert investors to risky investing pattern, but to provide informative reference to financial institutions in making policies or decisions about IPO.

생명공학은 기술의 특성상 보건 의료, 농업, 자원 환경, 에너지 등 광범위한 산업에 응용될 수 있는 고부가가치형, 두뇌기술집약형, 탈공해형, 자원 및 에너지절약형 기술이라는 특징을 지니고 있어 21세기 미래산업을 선도할 것으로 기대되고 있다. 본 연구의 목적은 생명공학기술이 1980년과 1990년 사이의 산업구조에 어떠한 변화를 초래하였는지를 알아보는 것이다. 생명공학의 산업경제적 파급효과를 분석해 보기 위해 한국은행에서 발행한 산업연관표를 이용하여 생명공학 관련산업의 지원에 따른 국내 제반산업의 생산변화율을 측정하였다. 정부의 지원이나 금리 및 세제의 혜택을 통해 생명공학 산업 관련 비용이 감소하게 되면 이에 따른 가격변화가 국내 산업발전과 고용의 증가를 갖는 것으로 믿어진다. 고정계수 아닌 변화계수를 특징으로 하는 본 모형의 접근방법은 생명공학에 대한 재정지원 및 세제 인센티브 등을 외생변수로 처리하여 산업구조 변화의 추이와 고용유발 등을 예측하였다. 본 논문의 가설은 생명공학의 영역이 점차 증대되어 나아가기 때문에 1980년의 제반산업의 영향은 1990년의 영향보다는 적어야 한다. 즉 생명공학 관련비용 하락이 전체산업에 미치는 1980년의 생산율 증가보다 1990년의 생산율 증가가 커야 할 것이다. 본 가설에 대한 검증의 과정에서 얻은 통계치를 통해 생명공학산업이 한국 산업 전체에 미치는 영향이 10년 동안에 그 차이가 거의 없어 미성숙 단계에 있다는 결론을 짓게 되었다. 따라서 생명공학 분야의 계속적인 발전을 위해서는 선진국 수준의 독자적 기술개발을 통한 국제 경쟁력을 강화해야 하는데 이를 위한 정부 및 민간기업 투자확대와 연구개발 지원체제의 확대가 요망되고 있다.

In this study, we examine how land use zoning affects the land price controlling other variables such as road-facing condition of the land, land form, land age after its development and land size. We employ geographically weighted regression analysis which reflects spatial dependency as methodology with a data sample of land transaction price data of Jangyu, a new town, in Korea. The results of our empirical analysis show that the respective coefficients of traditional regression and geographically weighted regression are not significantly different. However, after calculating Moran's Index with residuals of both OLS and GWR models, we find that Moran's Index of GWR decreases around 26% compared to that of OLS model, thus improving the problem of spatial autoregression of residuals considerably. Unlike our expectation, though, in both traditional regression and geographically weighted regression where residential exclusive area is used as a reference variable, the dummy variable of the residential land for both housing and shops shows a negative sign. This may be because the residential land for both housing and shops is usually located in the level area while the residential exclusive area is located at the foot of a mountain or on a gentle hill where the residents can have good quality air and scenery. Although the utility of the residential land for both housing and shops is higher than its counterpart's since it has higher floor area ratio, amenity which can be explained as high quality of air and scenery in this study seems to have higher impact in purchase of land for housing. On the other hand, land for neighbourhood living facility seems to be valued higher than any other land zonings used in this research since it has much higher floor area ratio than the two land zonings above and can have a building with up to 5 stories constructed on it. With regard to road-facing condition, land buyers seem to prefer land which faces a medium-width road as expected. Land facing a wide-width road may have some disadvantage in that it can be exposed to noise and exhaust gas from cars and that entrance may not be easy due to the high speed traffic of the road. In contrast, land facing a narrow road can be free of noise or fume from cars and have privacy protected while it has some inconvenience in that entrance may be blocked by cars parked in both sides of the narrow road. Finally, land age variable shows a negative sign, which means that the price of land declines over time. This may be because decline of the land price of Jangyu was bigger than that of other regions in Gimhae where Jangyu, a new town, also belong, during the global financial crisis of 2008.

We examine the methods to increase MBS values given parameters of default risks of individual mortgages and their correlation, and analyze the effects of these parameters on the efficiency of the methods. First, the values of MBS can be improved when they are comprised of low-correlation mortgages regardless of specific forms of investors' utility functions. Second, the values of MBS can also be raised even after their components mortgages are determined. More specifically, when investors' utilities are heterogeneous, CMO's of a less risky tranche and a riskier tranche are highly valued compared with pass-through securities of two identical tranches. When investors' utilities are homogeneous(risk averse), however, the latter meets the needs of investors better than the former does. Third, it can be shown that the efficiency of the methods in this paper is an increasing function of default risks of mortgage loans or of the correlation between them, and a decreasing function of the amount of the price fall of MBS when in default.

The use rate of M-pass(transportation card for foreigners),developed and sold to provide convenience to foreign tourists, was only 0.0051 % of visitors to Seoul over the past five years. Even this poor sales fell to the 0.024 % level in 2020 due to COVID-19. The cause of the sluggish performance was that the Ministry of land, Transport and Maritime Affairs and the card issuer excluded transportation operating organizations, and problems such as poor public relation, irrationality in pricing, and limitied number of sales locations appeared. In order to solve this problem, the research result showed that business strategies such as the establishment of a digital marketing system, realistic pricing, and the establishment of a mobile sales system that fit the trend, as well as the development of new product that reflect the participation and opinions of all related organizations are necessary. It is expected that this study will not only provide convenience to foreign Seoul tourist in the age of Post Corona, but also help improve the management of subway operating organizations.

Royalty contributed to the development of the non-fungible token (NFT) ecosystem as a reward system that pays a portion of the sales to the creator whenever transactions occur. This study quantitatively analyzes the impact of the abolition of royalties, which is being expanded by some NFT marketplaces, on the NFT market, and qualitatively analyzes the results of the impact. The analysis results are as follows. First, the number of NFT mints is decreasing by causing creators to leave the NFT market and reducing new entry. Second, major NFT projects have refused to trade with marketplaces that have abolished royalties, leading to a decrease in the number of transactions. Third, the abolition of royalties has undermined the motivation of NFT creators to continue to develop their projects, leading to a drop in NFT floor prices. This study is expected to contribute to reducing the current negative impact in the short term by suggesting how the NFT community provides incentives to owners who voluntarily pay royalties independently of the policy of the NFT marketplace. In addition, it suggests that in the long run, fundamental solutions to the problem of abolishing royalties require improvements in technology related to royalty payments, cooperation between NFT marketplaces and NFT creators, and institutional support related to royalties.
