The growth and employment effects of R&D investment were analyzed according to business size, export value and manufacturing sectors so as to suggest improvement directions for effective industry policies. The effect of R&D investment was considered simultaneously from the two perspectives of growth and employment effect, and the causality analysis was carried out by using a path analysis. The result of the path analysis confirmed significant differences in the growth effect of R&D investment depending on business size. However, the effect of increasing employment was difficult to obtain statistically significant results for any various combinations of business size and export value. This is a mixture of directions for the effects of R&D investment on employment, which could be due to the failure to consider appropriate time lags between investment and effect. Efficiency analysis by industry sectors confirmed significant differences in efficiency depending on business size, but differences depending on export value were difficult to identify. In order to derive improvement policy by industry sector according to business size and export value, the direction of selective support policy and universal support policy was derived for six industry groups by combining the return to scale in the efficiency analysis and R&D concentration. Hirschman-Herfindahl index is used for calculating R&D concentration.

1997년 노동당 정권 출범 이후, 영국 중앙정부는 지역발전정책의 분권화(예 : RDA의 설립, 지역의회 창설 등)를 대대적으로 추진하였다. 이러한 배경 하에서, 본고는 영국 Region 수준에서의 지역발전정책 분권화의 중요한 제도적 기반을 살펴보았다. 즉 2002년부터 시행되어 온 영국 중앙정부의 잉글랜드 9개 지역 RDA에 대한 포괄적 예산지원, 그리고 그에 대응해서 각 지역 RDA가 중앙정부와 합의 하에 설정한 지역발전 목표의 추구와 중앙정부의 실적 모니터링을 고찰하였다. 그리고 분권화된 지역발전정책의 필요성이 높아지고 있는 우리나라의 상황에 영국에서의 분권화가 제시할 수 있는 시사점 및 향후 과제를 간략히 논의하였다.

본 연구는 2002년 1월부터 2010년 4월까지의 기간 동안 우리나라 주식형 펀드의 자료를 이용하여 교차보조의 존재 여부에 대한 분석을 수행하였다. 분석 결과, 전체적으로 운용보수가 낮은 펀드로부터 운용보수가 높은 펀드로 성과의 이전이 이루어져 운용사가 투자자의 이익보다는 운용사의 이익을 극대화하는 행동을 선택함을 확인할 수 있었으며, 이러한 경향은 2008년 이후 강화된 것으로 나타났다. 또한 설정된 지 오래된 펀드로부터 신생 펀드로의 교차보조와 전 분기 수익률이 높은 펀드로의 성과 이전이 존재하나 2008년 이후 이러한 경향은 완화된 것을 확인하였다. 이러한 분석 결과는, 투자자 보호를 위해 투자자의 이익을 해할 가능성이 있는 거래에 대한 면밀한 감독과 운용사의 운용능력에 대한 평가가 종합적으로 이루어질 필요가 있음을 시사한다.

최근 IETF mobileip 워킹 그룹은 Mobile IPv6의 보안 문제를 가장 중요하게 다루고 있고, 홈 에이전트와 이동 노드는 IPsec을 적용하여 인터넷 보안을 제공하고, 상대 노드와 이동 노드는 RR과정으로 서로를 인증 할 수 있는 표준안을 제출하였다. 이동 노드는 자신의 흠 주소를 획득하여 인터넷 연결의 이동성을 보장받기 위하여 특정 라우터에게 홈 에이전트를 등록하고 흠 에이전트와 이동 노드는 IPsec 적용을 위한 보안 연계 정보를 교환할 수 있어 IPsec 적용이 가능하다. 반면 상대 노드와 이동 노드와 IPsec을 적응하기 위해서는 이동 단말기의 한계 및 IPsec 프로세싱의 부하로 RR과정을 통하여 상호 인증하는 메커니즘을 채택하였다. 본 고는 Mobile IPv6 환경에서 홈 에이전트와 이동노드사이에 IPsec 적용 방안을 위한 보안 연계 및 보안 정책 관리 방향을 제시한다.

This paper examines the investment efficiency of Korean venture capitals during 1987~2006 (20 years), focusing on their selection capability. Despite the Korean government's efforts, venture capital industry has evolved in a slow speed. Since the genesis of venture paradigm in Korea at 1997, venture capital industry as a macro unit has been fully discussed in Korean contexts. But venture capital's activities at micro level regarding each investment's outcome have not been examined. This study attempts to fill the voids of micro knowledge about each investment success rates by venture capitals. We analyzed venture investment records in 4,791 venture startups and their success rates. Their investment criteria were relevant to high potential industries and amount of tangible assets. But their criteria were not relevant to R&D intensity and financial growth of venture firms, which may indicate low level of maturity about Korean venture capital industry. We found that Korean venture capital's investment pattern may be originated from the low return of investment, so that efficiency of IPO markets is a prerequisite for the upgrade of venture capitals' efficiency. Some policy implications are discussed.

The study investigates the association between CEO education and firm performance with a sample of 85 nonfinancial firms listed on the Saudi stock exchange during 2018 applying ordinary least squares method. CEO education is defined by three variables, the level of education, if the degree-granting institution is domestic or foreign, and if the highest degree is in management or other fields of study. Financial performance is measured by return on assets and return on equity. Firm size, age, liquidity and growth are introduced as control variables. The study shows that 58 CEOs of the firms studied are graduates, 38 have obtained their degree from a domestic institution and 44 have a management degree. Graduate CEOs are found to enhance performance. Graduating from a domestic institution influences performance positively. Management degree of CEO does not seem to impact performance. Firm size, liquidity and growth are positively associated with performance. Firm age does not explain performance differences of firms. Results are robust to performance measures. The findings of the study suggest that firms can benefit from a CEO hiring policy that emphasizes on the minimum qualification set as graduation or higher, education from a domestic institution and no undue weight on management qualification.

This study analyzed the factors influencing the choice of new farming type in order to prepare the countermeasures against structural changes of farm labor force. The analytical model was the multinomial logit model(MNL). The test for Independence and Irrelevance Alternatives(IIA) assumption in MNL shows that the IIA assumption in our data is rejected. Alternatively, we chose the multinomial probit model(MNP) that does not assume IIA. Data were obtained from 2010 census of Agriculture, Forestry and Fisheries of Statistics Korea. New farming types are succession(13.9%), return-to-farming(45.0%), part-time-farming(32.5%) and etc(8.6%). Analysis results showed that the characteristics of farms, commodity, management, and region influenced the choice of new farming type. This study is expected to help policy makers to produce support policies by new farming types in order to increase the number of new farmers and to make them easier to settle down in agriculture.

Purpose: This study is to investigate the effect of managerial ownership level in distribution and service companies on the stock price crash. The managerial ownership level affects the firm's information disclosure policy. If managers conceal or withholds business-related unfavorable factors over a long period, the firm's stock price is likely to plummet. In a similar vein, management's equity affects information opacity, and information asymmetry affects stock price collapse. Research design, data, and methodology: A regression analysis is conducted using the data on companies listed on the Korea Composite Stock Price Index (KOSPI) between 2012-2017 to examine the effect of the managerial ownership level on stock price crash risks. Results: Logistic and regression results indicate that the stock price crash risk was reduced as managerial ownership levels are increased. The managerial ownership level has a significant negative coefficient on stock price crash risk, negative conditional return skewness of firm-specific weekly return distribution, and asymmetric volatility between positive and negative price-to-earnings ratios. Conclusions: As the ownership and management align, the likeliness of withholding business-related information is reduced. This study's results imply that the stock price crash risk reduces as the managerial ownership level increases because shareholder and manager interests coincide, thereby reducing information asymmetry.
