The aim of this study is to synthesize the rapidly increasing literature on privacy and security risk of digital payment. By reviewing 591 studies, the literature on this topic was evaluated using a bibliographical approach to highlight the intellectual development of the field and recommend potential research directions in this still-emerging field. According to our assessment, academics have continued to focus on perceived privacy and security, while more multigroup analyses based on subdimensions of risk are needed. In addition, the vast majority of studies have not considered the inter-relationship between risk attributes. We analyse the potential causes of the lack of research diversity and provide additional suggestions to improve digital payment research in the future. This study will be valuable for academics, analysts, regulators, practitioners, and investors.

In recent years, discussions on green purchasing have increased; most studies were concentrated in developed countries, with limited studies conducted in developing countries. This study aims to systematically analyze studies that have discussed green purchasing. Using the Scopus database, 142 studies from 61 journals published during the period 1998 to 2021 were analyzed. Our analysis focused on three fundamental aspects: the determinants, the effect of green purchasing, and exploring the theoretical foundations and the most common theories that the studies relied on. The analysis results focused on researchers’ demographic and physiological determinants based on the theory of planned behavior. There has been a development in discussing the determinants related to products and marketing and social and environmental determinants in recent years. The analysis results of the studies that addressed green purchasing show that green purchasing contributes to sustainable development. This study contributes to decision-makers by identifying the mechanisms of persuasion that motivate consumers to buy green products and provides a clear picture of the contribution of green purchasing to improving company performance and thus achieving sustainability, which encourages stakeholders to devise policies, promotional, and marketing strategies through which they can attract consumers.

Municipal bonds are an option available to many cities to raise long-term financing to finance the infrastructure projects. This study aims to develop and find local measures of creditworthiness that are suitable and applicable for local government units in Palestine. Different variables are recognized to see the effect on the issuance of municipal bonds, macroeconomic variables measured by revenues and expenditures per capita, cost of capital, and unemployment rate. Municipal status variables have subgroup variables of municipality size, financial reporting quality, outstanding debt, and financial distress. Various financial ratios, comparative and cross-sectional analysis, horizontal and vertical analysis were used. These ratios and analysis have been used to determine the municipal status variable. The results of the study were limited to the largest 11 sample municipalities; each is the central local government unit at the governorates and was not generalized for all municipalities in Palestine. The study found that macroeconomic and municipality status affects the issuance of municipal revenue bonds. Based on the study results, municipal bonds are highly recommended. Also, instructions from the Ministry of Local Government need to be established and to enforce municipalities about the declaration date of publishing audited financial statements.
