The collaborative filtering (CF) tends to recommend a user those items only connecting to similar users directly but fails to recommend the items with indirect actions to similar users. Therefore, CF performs poorly in the case of sparse data like Kickstarter. We propose a method of enabling indirect crowdfunding campaign recommendation based on bipartite graph. PersonalRank is applicable to calculate global similarity; as opposed to local similarity, for any node of the network, we use PersonalRank in an iterative manner to produce recommendation list where CF is invalid. Furthermore, we propose a bipartite graph-based CF model by combining CF and PersonalRank. The new model classifies nodes into one of the following two types: user nodes and campaign nodes. For any two types of nodes, the global similarity between them is calculated by PersonalRank. Finally, a recommendation list is generated for any node through CF algorithm. Experimental results show that the bipartite graph-based CF achieves better performance in recommendation for the extremely sparse data from crowdfunding campaigns.","PeriodicalId":38647,"journal":{"name":"Banking and Finance Review","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78948080","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bank capital executes the significant role of preventing the bank from failure and acts as a buffer against possible losses. Capital adequacy is the least amount of capital a bank has to preserve to execute the business, take advantage of profitable growth opportunities, absorb losses, and sustain the customers’ confidence on it. Several bank crises and bank defaults motivate the Basel Committee on Banking Supervision to provide a comprehensive guideline in managing bank capital. The capital adequacy regulation is an international standard to safeguard the banks through setting a risk-sensitive minimum capital requirement. The regulatory authority sets the regulatory capital, and the operating banks are required to maintain the adequate level of capital.","PeriodicalId":38647,"journal":{"name":"Banking and Finance Review","volume":"74 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78689659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For that purpose, the study uses time series data on a monthly basis from 2010:M1 to 2018:M8. The data are obtained from the Financial Services Authority (OJK) Indonesia and analyzed using vector autoregression (VAR). Some variables are employed to proxy risk vulnerability including financing-to-deposit ratio (FDR) as a proxy of liquidity risk, nonperforming financing (NPF) as a proxy of financing risk, and cost-to-income ratio (BOPO) as a proxy of operational risk. The findings suggest that financing risk is the most dominant risk triggering vulnerability on Islamic banks in Indonesia.","PeriodicalId":38647,"journal":{"name":"Banking and Finance Review","volume":"63 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83866428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data were collected from 66 IBs over 18 countries covering the period of 2007–2015 and analyzed using the System-GMM estimator. The findings indicate that an increase in SSB effectiveness increases IBs’ performance even during the crisis periods. A possible justification for this positive effect is related to the SG structure of IBs that allows them to undertake higher risks to achieve a high efficiency level. For this, the IBs, policymakers and practitioners should consider these findings when aiming to improve SG practices in the Islamic banking industry, which in turn may help in protecting IBs during crisis and non-crisis periods. More specifically, they should give due importance to SSB (size, cross-membership, educational qualification, reputation and expertise) in enhancing the performance of IBs during the crisis and non-crisis periods. This study provides additional evidence on how IBs can sustain their performance during either crisis or non-crisis periods through adopting appropriate SG structure. However, the study only focuses on a small sample of 66 IBs due to lack of the data.","PeriodicalId":38647,"journal":{"name":"Banking and Finance Review","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88271719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is mostly based on the use of Web and represents a unique category of fundraising, with different vehicles, processes and goals. It is very diffused in the global economic landscape and in Italy where a specific discipline for crowdfunding was introduced for the first time in Europe. The chapter, after a summary of the peculiarities, spread and regulation of crowdfunding, intends to analyze the characteristics of a platform operating on the Italian market (Produzioni dal Basso), highlighting its characteristics, strengths and weaknesses. The work also intends to carry out a simulation for the realization of a crowdfunding project by an Italian Foundation operating in the social sector of child and adolescent distress, to be implemented through the use of the same platform.","PeriodicalId":38647,"journal":{"name":"Banking and Finance Review","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79015745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
