Fitting Multi-Layer Feed Forward Neural Network and Autoregressive Integrated Moving Average for Dhaka Stock Exchange Price Predicting

The stock market plays a vital role in the economic development of any country. Stock market performance can be measured by the market capitalization ratio as well as many other factors. The primary purpose of this study is to predict the movement of the stock market based on the total market capitalization of the Dhaka Stock Exchange (DSE) using autoregressive integrated moving average (ARIMA) models as well as artificial neural networks (ANN). The data set covers monthly time series data of total market capitalization from November 2001 to December 2018. This study also shows the best model for forecasting the movement of DSE market capitalization. The ARIMA (2,1,2) model is chosen from among the several ARIMA model combinations. From several artificial neural networks (ANN) models as a modern tool, a three-layer feed-forward topology using a backpropagation algorithm with five nodes in the hidden layer, one lag, and a learning rate equal to 0.01 is selected as the best model. Finally, these selected two models are compared based on the Root-Mean-Square Error (RMSE), Mean Absolute Error (MAE), Mean Absolute Percentage Error (MAPE), and Theil’s U statistic. The results showed that the estimated error of ANN is less than the estimated error of the traditional method. Doi: 10.28991/ESJ-2022-06-05-09 Full Text: PD

Bubble identification in the emerging economy fuel price series: : Evidence from a generalized sup augmented Dickey–Fuller test

n the recent past, the world in general and Pakistan in particular faced a drastic fuel price change, affecting the economic productivity of the country. This has drawn the attention of empirical researchers to analyze the abrupt change in fuel prices. This study takes a lead and investigates for the first time, in the literature related to Pakistan, the presence of multiple fuel price bubbles, with the purpose of knowing if the price driver is due to demand or it is exuberant consumer behavior that prevails and contributes to a sudden boom in fuel price series. The empirical analysis is performed through a recently proposed state-of-the-art generalized sup ADF (GSADF) approach on six commonly used fuel price series, namely, LDO (light diesel oil), HSD (high-speed diesel), petrol, natural gas, kerosene, and MS (motor spirit). The bubble analysis for each of the six fuel price series is based on monthly data from July 2005 to August 2020. The findings provide evidence of the existence of multiple bubbles in all series considered. Specifically, four bubbles are detected in each of the kerosene and natural gas price series, whereas three bubbles are noted in each of the HSD, LDO, petrol and MS price series. The maximum duration of occurrence of bubbles is of 12 months for kerosene. The date-stamping of the bubbles shows that the financial crisis of 2008 contributed to the emergence of bubbles that pushed oil prices upward and caused a depreciation in the national currency.Peer reviewe

Customers' preferences in selecting Islamic banks in Gulf Cooperation Council (GCC) countries

The present study aim to investigate relationship between religion, higher profitability on investment, sharia board audit, services (faster/friendly), bank reputation, product and service quality and to know which variable more influence in selecting Islamic banks in GCC countries. The study adopted convenience sampling. 101 completed questionnaires were chosen for analysis. The study found that there is no relationship in between consumer preferences and higher profitability on investment, services (faster/friendly), bank reputation, but there is, however, a significant relation with regards to religion, sharia board audit and product and service quality and paper provide fresh insights to the Islamic banks and recommendations, study implications, future research possibilities also discussed

Employee-Perceived Corporate Social Responsibility (CSR) and Employee Pro-Environmental Behavior (PEB): The Moderating Role of CSR Skepticism and CSR Authenticity

Despite the substantial attention given to pro-environmental behavior (PEB) by academicians, practitioners, and policymakers, few studies have investigated how employee-perceived corporate social responsibility (CSR) affects employees’ PEB. Moreover, though the concept of PEB has been found to elicit a wide range of positive benefits for employee behaviors and attitudes, it has rarely been applied to the context of the manufacturing sector. Underpinned by the social identity theory (SIT) and the attitude-behavior-context (ABC) theory, the present study investigates the impact of employee-perceived CSR on employees’ PEB through the moderating roles of employee–CSR skepticism and employee–CSR authenticity. The convenience sampling technique was used to select employees from Pakistani manufacturing firms to participate in the study’s survey. Analysis results of data from 235 respondents across 115 manufacturing firms suggest that employee-perceived CSR positively drives employees’ PEB. In addition, the findings offer valuable insights on employee–CSR skepticism and employee–CSR authenticity. Specifically, CSR skepticism weakens the link between perceived CSR and PEB, while CSR authenticity strengthens this link. By providing implications and limitations, the present study discusses that organizations can convey the message of their credible, genuine, and authentic CSR efforts to their employees for social, economic, and environmental wellbeing. The study’s discussions and conclusions are presented

Does Corporate Social Responsibility Impact on Corporate Risk-Taking? Evidence from Emerging Economy

This study analyzes the impact of corporate social responsibility (CSR) fulfillment on corporate risk-taking to assist stakeholders in identifying the “double-edged sword” role of CSR activities and provide empirical evidence for enterprises to properly carry out CSR activities. The results show that the self-interest instrumentalization of CSR activities intensifies agency conflict, and CSR fulfillment weakens risk-taking to a certain extent. When CSR fulfillment reaches a certain value, CSR activities can improve risk-taking. Then, CSR fulfillment and risk-taking show a U-shaped relationship. Further analysis shows that the impacts of CSR on debt financing and R&D input reflect the U-shaped effect pathways of CSR fulfillment on risk-taking. Finally, it is suggested that CSR activities should be avoided to become the “self-interest tool” of the management. The regulators guide enterprises to break through the inflection point of the U-shaped effect and consider more for the stakeholders’ overall interests. Additionally, the regulators establish an effective compensation system to ensure that the enterprises with adequate CSR fulfillment obtain high-quality capital resources and promote the sustainable development of the capital market

The Mediation Effect of Carbon Accounting in Relation to Carbon Risk Management and Carbon Performance of Malaysian Companies

This paper enhances the knowledge on carbon management among organizations certified by the Malaysian International Organization for Standardization (ISO) 14001. Specifically, the study investigated the impact of carbon risk management on carbon performance through the mediation of carbon accounting. This research adopts a quantitative method with a final sample size of 136 and structural equation modeling (SEM) was employed to analyze the data. The findings suggest that carbon risk management and carbon accounting have a significant positive effect on carbon performance. Notably, carbon accounting exerts a full mediating effect on the relationship between carbon risk management and carbon performance

Determining Financial Uncertainty through the Dynamics of Sukuk Bonds and Prices in Emerging Market Indices

The main focus of the study is to determine the financial uncertainty while examining the Sukuk bonds prices, Sukuk bond and global emerging market indices returns dynamics. The study, with a time period ranging from 2017 to 2020, applies the quantile regression technique. The study findings show that evidence of co-moment exists between the global emerging market index and Sukuk bond price returns, except the one. There is no impact of the financial uncertainty indicator reflected by the global volatility index (VIX) on the Sukuk index returns, and even this impact is negative for (VXEEM). The causal impact among the global emerging and Sukuk bond markets will help formulate future trading strategies in particular to Islamic bond markets
