본 연구는 패널회귀분석을 활용하여 연안여객선 취항계획 특성분석을 수행하는 것을 목적으로 한다. 분석결과 GLS와 고정효과 분석결과 결항일수와 여객수송실적은 취항계획에 정의 영향을 끼치며 화물수송실적과 운임수입은 모형별로 상이한 것으로 나타났다. 또한 LSDV 및 OLS분석을 통해 지방청별로 군집을 이루는 경향을 확인하였다. 이는 지방청마다 여객선업체 및 선박의 잦은 변동이 존재하며 무조건적인 선박의 증편보다는 다양한 측면에서 심도있는 계획이 필요함을 나타낸다. 후속 연구에서는 항로별, 선종별로 나누고 세부적인 요인을 추가적으로 분석하여 보다 세밀하고 실무적인 결과를 도출해야할 필요성이 있다.

Objectives: This study aimed to examine how the relationship between socioeconomic factors at the macro level and suicide mortality rate of Korea was different from that of other OECD countries. Methods: We created OECD panel data of 29 OECD countries from 1985 to 2006 and analyzed the relationship between socioeconomic factors and suicide mortality rate for separate age and sex groups using a fixed-effect model. Economic factors included per capita GDP, per capita GDP growth rate, unemployment rate, and women's economic participation rate. Social factors included birth rate, alcohol consumption, and the percentage of population 65 and older. Results: Unemployment rate had a positive relationship with suicide in other countries but it had a negative relationship in some groups of Korea. Women's economic participation rate was both positively and negatively related with suicide in Korea but it did not relate to suicide in others. The negative relationship of birth rate and the positive relationship of alcohol consumption with suicide were evident in Korea, which were not found in other countries. The percentage of population 65 and older was negatively correlated in some female groups in Korea, while no significant relationship was found in other countries. Conclusions: Korea was substantially different from other OECD countries in the relationship between socioeconomic factors and suicide mortality rate.

1970년대 오일쇼크 이후 많은 국가들이 석유에 대한 에너지 의존도를 줄이는 정책을 펼쳤다. 특히, 한국은 빠른 속도의 탈석유화가 일어났으며, 이러한 탈석유화는 급속한 전기화로 이어져 전력수요 급증의 한 요인이 되었다. 본 연구에서는 OECD 34개국을 대상으로 한 1985년부터 2011년까지의 패널자료를 이용하여 탈석유화와 전기화의 관계를 분석함으로써 최근 벌어지고 있는 전력수급난에 대한 정책적 시사점을 제공하고자 한다. 패널분석을 위해 확률효과모형 및 고정효과모형을 적용하였 다. 분석결과 총에너지 소비에서 에너지유 소비 비중(탈석유화 척도)이 10%p 증가하면 전력 소비량이 약 15% 감소하는 것으로 나타났다. 특히 산업용 전력소비가 전체 전력소비에서 차지하는 비중을 국제 비교해보면 우리나라의 경우 OECD 34개 중 4위(2011년 기준)로 나타나는 등 주로 산업부문에서 석유에서 전력으로의 급격한 수요 전환이 현재의 전력수급 위기의 주요 원인 중 하나라는 점을 알 수 있다.

Purpose - This study empirically analyzes the effects of food delivery service use frequency and the proportion of single-person households on the generation of MSW (Municipal Solid Waste). Additionally, the study analyzes MSW increase during the COVID-19 period. Design/methodology/approach - The study uses annual information on MSW and related characteristics of 228 Si, Gun, and Gu, which are administrative districts of Korea, from 2015 to 2020. Panel fixed effect model is employed for estimations. Findings - The study finds that food delivery and single-person household have significant effects only on recyclable and standard garbage bag MSW, respectively, not on all produce types of MSW. Additionally, it is estimated that, during the COVID-19 period, the increasing effect of food delivery is intensified while single-person households diminish its increasing effect. Lastly, the study confirms that the marginal effect on the increasing effect of MSW generation by the number of household members. Research implications or Originality - The estimated results are expected to provide useful information for the related policies. In particular, it is necessary to focus more on recyclable MSW concerning the developing delivery culture, and regarding changes in the family structure, focus more on the number of household members than single-person households.

This study investigates the effect of chief executive officers (CEO) demographic characteristics such as age, functional experience, education, and gender, on corporate leverage decisions. This study investigates the independent commissioner's role in moderating the relationship between CEO demographic characteristics and leverage decisions. The data used is panel data with a sample of 283 non-financial companies listed on the Indonesia Stock Exchange (BEI) from 2010-2017. Moderated regression analysis is used as an analytical technique, with the selected model fixed effects model. The results showed that male and young CEOs were more risk-averse, so they tended to use debt more. However, this study found no evidence of the effect of CEO experience and education on leverage. This study finds evidence that independent commissioners reduce the influence of CEO age and gender on leverage decisions. It shows the role of independent commissioners in controlling risk-taking from male and young CEOs related to leverage decisions. These results become input for companies to consider demographic characteristics in choosing a CEO. Also, companies need a board (in this study seen from independent commissioners) that is strong enough to control the CEO regarding risky decision making, such as leverage decisions.

Purpose: The purpose of this study was to examine the relationship between portfolio quality and financial sustainability of microfinance institutions in Kenya. Research Design, Data, and Methodology: The analysis was based on a panel dataset of 30 microfinance institutions for the period of 2010 to 2018. Data was obtained from the Microfinance information exchange (MIX) database, and it was analyzed through descriptive and inferential statistics with the aid of STATA. Based on the results of the Hausman test, the study adopted the fixed effect regression model to test the research hypothesis. Results: The study found that portfolio quality had a positive significant effect on financial sustainability of Microfinance institutions in Kenya (β= 0. 211; p-value < 0.05). For the control variables; firm age had a positive effect (β= 0.773; p-value <0.05), while firm size (β= -0. 749; p-value < 0.05) had a negative effect on financial sustainability. Conclusions: The study concluded that portfolio quality has an important influence on the financial sustainability of microfinance institution. The study recommends that managers of microfinance institutions should devise good collection policies to improve portfolio quality while lessening loan default rate. The portfolio quality may improve the overall profitability and enhance investor confidence in their strategic decision-making on refinancing.

Purpose: This research aims to analyze the quality and characteristics of foreign tourists to Indonesia. Research design, data and methodology: The indicator used to see the quality of foreign tourists is their expenditure while in Indonesia. The data used is secondary data and the statistical analysis used is panel data regression to see the effect of Economic Distance, GDP per capita, Average Length of Stay and Exchange Rate on the quality of Foreign Tourists from 2010 to 2019. Results: Foreign tourists to Indonesia are dominated by young tourists, male and stay about 8.87 days. Their expenditure is relatively low, mostly spent on accommodation, food and beverage. The variables of average length of stay, exchange rate, economic distance, and GDP per capita have a significant and positive effect on the quality of foreign tourists to Indonesia. Conclusions: The number of foreign tourists visiting Indonesia in 2010-2019 tends to increase where the majority of tourists come from countries that are geographically close to Indonesia, young tourists, and male. The quality of tourists in terms of spending is still relatively low. The characteristics of foreign tourists and economic indicators used in the study have a positive effect on improving the quality of tourists.

Purpose - In this study, we investigate the effects of government environmental subsidies and the globalization Chinese firms on their profitability using return on assets (ROA). Design/methodology/approach - In this study, a merged data including accounting, financial market, subsidization of the Chinese governments, local and the central, and export activities of 19,563 year-firms, for those listed on Shanghai Stock and Shenzhen Stock Exchange for 11 years from 2008 to 2018 is used. We collect subsidy data from RESSET database and financial data from CSMAR database. Then, we empirically test the test hypotheses using fixed effects models (FEM) separately and in a simultaneous equation model (SEM). Findings - Firstly, the globalization of Chinese firms has a negative impact on their profitability for some years after the year. Secondly, environmental subsidies just like other subsidies have ameliorating effects on financial performance for global firms. Such effects have lasted some years. Thirdly, environmental investments have a mostly negative impact on short- and long-term profitability for global firms. Lastly, the government's environmental subsidies in China have a positive effect on their profitability for both global and domestic firms. Research implications or Originality - We can infer that environmental investments with the help of the governmental subsidies can help Chinese firms deploy global strategies to expand markets to surpass competitors in the long run despite worsening profitability in global markets in the short run.

본 연구는 중국의 1985년부터 2008년까지의 각 성 시에 관한 패널데이터를 활용해서 재정분권화가 경제성장에 미치는 영향을 실증분석한다. 재정분권화를 위해 최근에 개발된 지표를 사용하고 지방정부의 자율재량권을 계량화해서 모형에 반영하여 다음의 결론을 얻는다. 인플레이션율의 증가는 중국경제에 긍정적인 영향을 미치는 것으로 나타났는데 이는 필립스커브에 의하면 고용량의 증가로 대변되는 중국경제성장과 상충되는 개념으로서 향후 중국경제의 불안정성을 암시하고 있다. 중국의 WTO가입은 중국경제에 긍정적인 역할을 해온 것으로 나타났는데 이는 고전학파의 자유무역이론을 뒷받침하는 실증결과로 해석할 수 있다. 지출분권화는 중국경제성장에 긍정적인 영향을 미치고, 또한 세입분권화도 지출분권화만큼 크지는 않지만 경제성장에 긍정적인 영향을 끼쳤다. 국세나 지방세를 많이 부과하면 경제성장에 부정적인 영향을 미치는 것으로 나타났고, 기대와는 달리 지방정부의 자율재량권을 계량화해서 반영한 지표는 경제성장과 관련이 없는 것으로 나타났다.
