Purpose - The purpose of this paper is to find out the determinants of the quality of financial information in the financial environment of the cement companies of Bangladesh. Research design, data and methodology - This study considers a total of fifty-eight firm years as the sample from the seven listed cement companies of Bangladesh during the period of 2007 to 2015. This study applies the multivariate regression analysis including the pooled OLS, panel and controlling time. Results - This study finds that profitability and external financing are the two major explanatory variables in determining the quality of financial information. This study also finds that firm size and accrual quality don't have any significant influence on quality of financial information. Conclusion - This study observed that profitability of this sector which is much volatile and prone to be manipulated. Thus, this paper suggests that higher profitability needs more scrutiny while assessing quality of financial information. Finally, this study provides some indications for future research such as considering the listed firms of other sectors of Bangladesh or cross country comparison in different country setting.

According to recent statistics, the number of family-owned small business have increased. And these growing numbers have created an urgent need for researchers and government to analyse and plan for this population. The purposes of this study were to identify the determining factors of the location of family owned small business and to analyze the factors related to their job satisfaction, and life satisfaction. The data used for this study, were 713 self-employed men and women which were elected from the panel data of 1998 MIPS of Daewoo Economic Research Institute. Statistics performed for the analysis were frequencies, percentiles, t-test, $\varkappa$$^2$, OLS and Logistic analysis. It was found that the person who work at home-base small office were the residents of smaller city, and are older than the office-going attendants. The variable which effects the job satisfaction of the home-based workers was the educational background. And sex was the only factor which affects the job satisfaction of the office-going attendants. It was also found that job satisfaction affects the life satisfaction significantly in both group.

The study aims to investigate whether Musharakah management has an impact on Chinese and Malaysian business partnerships. To estimate the relationship between Musharakah and the Sino-Malaysian partnership, this study uses a panel econometric technique namely pooled ordinary least squares. Ordinary Least Squares regression (OLS) is a common technique for estimating coefficients of linear regression equations which describe the relationship between one or more independent quantitative variables and a dependent variable. Data was retrieved from the annual reports (from 2009 to 2019) of non-financial firms listed on the stock exchange of China and Malaysia. Four partnership measures (i.e., Musharakah, Mudarabah, Tawuruq, and Kafalah) were used to estimate the impact of Musharakah on the Sino-Malaysian partnership. Empirical results reveal that Musharakah and Mudarabah are positively related to Kafalah but the relationship is statistically insignificant. Alternatively, Musharakah is positively and significantly related to Mudarabah. Musharakah and Mudarabah have a positive but insignificant relationship. The findings of this study suggest that management of partnership has a positive impact on firm partnership. Furthermore, it supports the hypothesis that improving partnership enhances Musharakah, which has a positive impact on the firm's partnership.

This study aims to investigate the impact of COVID-19 pandemic on the stock markets of sixteen countries. Pooled OLS regression, conventional t-test and Mann-Whitney test are used to estimate the results of the study. We construct a weekly panel data of COVID-19 new cases and stock returns. Pooled OLS estimation result shows that the growth rate of weekly new cases of COVID-19 negatively predicts the return in stock market. Next, the returns on leading stock indices of these countries during the COVID-19 outbreak period are compared with returns during the non-COVID period. We use a t-test and Mann-Whitney test to compare the returns. The results reveal that investors in these countries do not react to the media news of COVID-19 at the early stage of the pandemic. However, once the human-to-human transmissibility had been confirmed, all of the stock market indices negatively reacted to the news in the short- and long-event window. Interestingly, we noticed that the Shanghai Composite Index, which was severely affected during the short-event window, bounced back during the long-event window. This indicates that the Chinese government's drastic measures to contain the spread of the pandemic regained the confidence of investors in the Shanghai Stock Market.

본 연구는 1820년부터 2006년까지 세계인구와 세계 산출량인 국민소득의 수준과 표준화 추이 및 패널 분석을 바탕으로 인구와 산출량이 부(-)의 관계라는 맬서스 가설을 재조명하였다. 실증분석 결과에 의하면 세계경제에서 맬서스 국면이 1900년부터 1994년의 기간 동안 나타났으며, 개별 국가의 경제성장 단계도 맬서스 국면을 경험했던 것으로 분석되었다. 그러나 1995년 이후 인구가 큰 폭으로 감소하고, 산출량이 급격하게 증가하면서 맬서스 국면은 유효하지 않은 것으로 나타났다. 이런 현상은 급격한 기술진보를 바탕으로 오히려 산출량이 기하급수적으로 증가했지만, 인구는 출산율 감소와 같은 사회적 현상으로 인해 큰 폭으로 감소한 것에 따른 것으로 보인다. 인구가 생산활동에 기여하는 방식이 양적 증가보다 자본이 체화된 인적 자본으로 전환된 것도 또 다른 요인이라고 볼 수 있을 것이다. 또한, 인구의 수요 창출 효과도 함께 고려한다면 인구의 경제적 역할은 지속적인 진화 과정을 거치게 될 것이다.

Purpose - This paper empirically investigates the relationship between country governance quality and worker remittances from foreign countries. Because remittances can be a source of funds for economic development and smoothing economic crises in developing countries, the related topic has been a concern for policy-makers and academic researchers. This paper divides the motives of remittances into altruistic and investment motives through existing papers, and then considers the governance quality the remittance receiving country as one of the determinants of remittances. Design/methodology - Our empirical model considers whether governance quality can affect the volume of remittances, and uses altruistic and investment factors studied in the literature. To do this, a two-step approach is taken. First, the panel data are examined via pooled OLS, random effects, and Tobit estimation. Second, the paper reduces six governance indicators into one variable, Governance, using the principal component technique (PCA) for a robustness check. Findings - The main findings can be summarized as follows. The negative governance variable in the estimation results shows a lower governance quality that induces workers to send savings to their home countries. This means that a country with poor governance quality seems to have more remittance inflows from abroad. It also reveals that poor governance quality is more relevant to an altruistic motive rather than an investment motive, in general. The positive per capita GDP variable shows the investment motive for developed countries. Originality/value - Existing papers have focused on various factors related to the motives of remittances. However, governance quality effects on remittance inflows have not been fully studied so far. This paper considers governance quality in an estimation equation explicitly as one of the determinants of remittances. This area of study is needed, in theory and empirically, in order to fully understand the relationship between governance and remittances.

Objective: Using the Korean Health Panel data (KHP) of 2008 and 2009, this paper analyzed the effect of antihypertension medication adherence on the changes in medical service utilization and medical expenditure in the next year. Method: Through a face-to-face interview survey, KHP has provided an extensive data on demographic characteristics, medical utilizations behavior, medical expenditure and health behaviors of the targeted households and their members since 2008. KHP is recognized as highly accurate regarding medical expenditure in that it makes the target households to record 'Health diary' whenever they use healthcare service, which could minimize their cognitive bias or memory distortion. The 2010 KHP data was based on the interview from 6,432 households and 19,697 household members. Two part model was used to explore the effects of medication adherence on medical use (logistic regression analysis) and medical expenditures (OLS). Result: Our study result demonstrated that the 74.7% of the patients who strictly adhere to their medication in both years, in 2008 and in 2009, were likely to use inpatient service in 2010. This shows the noncompliant patients were in fact use emergency service less than the compliant patients. Conclusion: Based on our analysis, this paper concludes that the high medication adherence of hypertensive patients could contribute to reduce the emergency service use. Therefore it is highly recommendable for the Korean government and the insurer, NHIS, to actively invest in developing education and promotion program to improve medication adherence among hypertensive patients.

본 논문의 논제는 국내 기업들, 특히 재벌계열사들 중심의 최근의 재무적 현안이 되고 있는, 현금유동성 수준에 대한 재무적 결정요인들에 대한 분석이다. 연구의 특징은 재벌소속 계열사들의 동 유동성에 대한 재무적 결정요인들에 대한 기존 연구(김한준 (2015))에 관한 확장, 심층적 연구이며, 이를 통하여 기존의 검정된 결정요인들에 대한 다양한 계량 경제적 모형들을 활용한 강건성 확인이 연구목적이라고 할 수 있다. 다양한 연구방법들이 검정에 응용되었으며 (정적, 동적 패널자료모형, 변수선택법, 파마-맥베스 모형 등) 연구결과 관련, 유의성있는 재무적 결정요인들로서는 현금흐름, 시가대비 장부가, 대리인비용, 그리고 추가적 설비투자비용 등이 판명되었다. 이는 기존의 연구결과와도 일관성이 있는 것으로 판단된다. 본 연구를 위하여 추가 투입된 잠재변수들 중, 현금전환기간과 산업더비변수들 (음식료업, 화학업, 건설업 등)이 종속변수에 대한 영향력에서 통계적 유의성을 보였다. 본 연구결과가 해당기업들의 적정 현금유동성 수준의 정책적 결정에 실증적 기준을 제공하여, 국내 자본시장의 선진자본시장으로의 진입 가능성에도 일조할 수 있기를 기대한다.
