Primarily because the entity that controls Bitcoin, its community of users, does not take actions to stabilize and secure the cryptocurrency – that is, in the manner that nations’ monetary policies can stabilize and secure national currencies – the author evaluates Bitcoin as untrustworthy. The author then offer an argument that its untrustworthiness undermines Bitcoin’s ability to serve both as medium of exchange and as store of value. Bitcoin’s untrustworthiness does not, however, undermine its usefulness as a speculative investment. Finally, the author discuss the extent to which – and how – other cryptocurrencies can avoid the evaluation that they are untrustworthy.","PeriodicalId":287910,"journal":{"name":"Disruptive Innovation in Business and Finance in the Digital World","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114079677","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}

Of the methodologies used to test for anomalies, the data-driven panel and quantile regressions were empirically found to be better suited over the traditionally common approaches to describe the non-linear, switching behavior of the anomalies. In the developed markets, the statistically significant small firms (size) had the highest average returns. In the developing markets, the lower price-to-earnings (P/E) ratios (value) had the highest average returns. In addition, the research found (1) a small country effect, (2) sales had a negative relationship with returns, and (3) a lower (higher) book-to-market (B/M) was associated with higher returns in the developed (developing) markets, indicating investors received a higher premium for growth (value) equities. The semi-strong form of the efficient market hypothesis was also found to be violated. The anomalies’ behavior varied between sorted portfolios, industries, and developed to emerging markets; though it was found to be consistent through time (not disrupted by bear or bull markets).","PeriodicalId":287910,"journal":{"name":"Disruptive Innovation in Business and Finance in the Digital World","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117138756","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}

Traditionally, buyers and suppliers linked together in a supply chain have conflicting objectives as manifested by a zero-sum payoff structure. Suppliers want their invoices to be paid quickly in order to reduce their need for working capital. In contrast, buyers want to delay payment of invoices as long as possible in order to reduce their need for working capital. In other words, suppliers want a short cash conversion cycle; buyers want a long cash conversion cycle. This conflict is eliminated by the insertion of a financial intermediary (supply chain finance bank) between the buyer and the supplier. The bank eliminates the conflict by: (1) using its balance sheet to decouple the cash conversion cycles of the buyer and supplier; and (2) providing cheaper financing to impatient suppliers and reluctant buyers (since the bank has a higher credit rating than both the supplier and the buyer).","PeriodicalId":287910,"journal":{"name":"Disruptive Innovation in Business and Finance in the Digital World","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127781636","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}

{"title":"Cryptocurrency Tide and Islamic Finance Development: Any Issue?","authors":"M. Abubakar, M. Hassan, Muhammad Auwalu Haruna","doi":"10.1108/s1569-376720190000020019","DOIUrl":"https://doi.org/10.1108/s1569-376720190000020019","url":null,"abstract":"Cryptocurrencies are hidden monies that are specifically created to be used as digital currencies while assuming the characteristics of real money. Barring the divergent opinions on whether permitted in Islamic law (that is/are halal) or forbidden in Islamic law (that is/are haram), and for which the swing tends to be in favor of its blockchain underlying technology permissibility in Islam, cryptocurrencies are undoubtedly indicating potential for relevance in the global trade, investment, and other contract settlements in some years to come. The potential of the blockchain technology is phenomenal with recent estimates suggesting it will be worth more than $20 trillion in just two years, which is more than the entire American economy. Since fortunes are made by those entrepreneurs and indeed savvy investors who have discerned its future potential earlier on, there exists some great temptation for people to jump on the blockchain bandwagon. Apparently the growing acceptability of digital fiat money as a result of technology development on one hand, and the failure of the paper money to mitigate inflation and other economic disequilibria since the disappearance of the gold standard on the other, various forms of cryptocurrencies including Bitcoins (referred to as the king) appear to roar toward wider recognition. However, an emerging phenomenon associated with cryptocurrency revolution is an observed significant fluctuation (the tide) in its value and thus a subject of discussion within Islamic finance community and beyond. In the midst of this also is the current agitation founded on some of the Islamic law (Sharīʿa) view on the necessity of asset-backed money, to be extended to the current cryptocurrency innovation for its transformation into a Sharīʿa compliant precious metal backed currency. The big question now which this chapter sought to provide the answer is, what are the implications of these developments to a more established and widening global phenomenon of Islamic finance and its development in Muslim world vis-a-vis aspirations for sustained economic development. The work finds that cryptocurrencies would generate three advantages over all forms of money including gold through: establishing a unified financial system through its standard decentralization, being rarer than gold and its significant mitigation of inflation. It is also noted that the prevalent foreign exchange risk resulting from the underlying activities (rather than the currency itself) is free from speculation (Gharar). It is, therefore, recommended that stakeholders in the Islamic Finance world should not be passive but be proactive in commencing processes to develop technical notes, standards, and operational guidelines to partake in the inevitable migration to cryptocurrencies.","PeriodicalId":287910,"journal":{"name":"Disruptive Innovation in Business and Finance in the Digital World","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129460323","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}

The authors focus on how these innovative technologies can impact the firms by creating values as part of corporate strategy, and by changing the way employees work.

To represent this complicated behavior, recent studies have emphasized the use of autoregressive models frequently concluding that generalized autoregressive conditional heteroskedasticity (GARCH) models are the most adequate to overcome the limitations of conventional standard deviation estimates. Some studies have expanded this approach including jumps into the modeling. Following this line of research, and extending previous research, our study analyzes the volatility of Bitcoin employing and comparing some symmetric and asymmetric GARCH model extensions (threshold ARCH (TARCH), exponential GARCH (EGARCH), asymmetric power ARCH (APARCH), component GARCH (CGARCH), and asymmetric component GARCH (ACGARCH)), under two distributions (normal and generalized error). Additionally, because linear GARCH models can produce biased results if the series exhibit structural changes, once the conditional volatility has been modeled, we identify the best fitting GARCH model applying a Markov switching model to test whether Bitcoin volatility evolves according to two different regimes: high volatility and low volatility. The period of study includes daily series from July 16, 2010 (the earliest date available) to January 24, 2019. Findings reveal that EGARCH model under generalized error distribution provides the best fit to model Bitcoin conditional volatility. According to the Markov switching autoregressive (MS-AR) Bitcoin’s conditional volatility displays two regimes: high volatility and low volatility.","PeriodicalId":287910,"journal":{"name":"Disruptive Innovation in Business and Finance in the Digital World","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133764984","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}
