    Blue Economy of Bangladesh: Opportunities and Challenges for Sustainable Development
    (Advances in Social Sciences Research Journal, Society for Science and Education, United Kingdom, 2018-08-25) Islam, Md. Khairul; Rahaman, Mahbubur; Ahmed, Zobayer
    The blue economy refers to the economic activity based on maritime resources. The paper aims to explore the current scenario of sea resources of Bangladesh. Using secondary data, the study reveals that Bangladesh can accelerate its economic growth through the sustainable use of the sea resources. Moreover, Bangladesh has 710 km long coastline with 200 Nautical Miles of an exclusive economic zone inside the Bay of Bengal. Marine fisheries contribute 19.4% of the total fish production of the country. Besides, the western coastline of Cox’s Bazaar is the longest sea beach in the planet that is visited by on an average, 81% of the international tourists arrive in Bangladesh. However, due to lack of institutional capacity and given the socio-cultural context, the sustainability of the sea resources is now facing critical threats. Apart from studying the present status of sea resources, the paper proposed some way forwards based on existing opportunities and challenges for promoting sustainable development in Bangladesh

    Predicting the Stock Market Efficiency in Weak Form: A Study on Dhaka Stock Exchange
    (EconJournals, 2018) Pervez, Masud; Rashid, Md. Harun Ur; Chowdhury, Md. Asad Iqbal; Rahaman, Mahbubur
    This study aims to examine the efficiency of Dhaka Stock Exchange (DSE) in the weak form using random walk model of Efficient Market Hypothesis (EMH) based on daily return series. The study applies both non-parametric (Kolmogorov–Smirnov test with Lilliefors coefficient, run test) and parametric test (autocorrelation test, unit root test and variance ratio test) on DSE general index, DSE broad index (DSEX) and DSE30 index ranging from June 1, 2004, to March 18, 2018. The results of the study show that the normality test and unit root test reject the null hypothesis of randomness while the result of the run test shows that only the share prices of DSE30 index follow the random walk out of three indices. Besides, the return series of DSE broad index show some signs in favour of randomness by autocorrelation test and the returns of DSE general index support the efficiency concerning variance ratio test under both homoscedastic and heteroskedastic assumptions. The overall results of the study show inefficiency of DSE in the weak form which means the investor has a chance to make an abnormal profit predicting the historical data. This study also provides valuable insight to the shareholders, investors, the board of directors and regulatory bodies.
