| Abstract: | We explore the potential of different behavioral drivers for people to use cash when presented with digital payment alternatives in retail transactions. Behavioral finance traits in our study include the otherwise neglected emotional drivers. We conducted an online survey targeting university educated adults in sub-Saharan African countries, a continent characterized by lower levels of banking penetration, intensive use of cash, and increased popularity of mobile money accounts to reduce financial exclusion. We obtain robust evidence that the affect heuristic is the only relevant behavioral trait determining the use of cash and of payments with credit cards, while there is no evidence of behavioral drivers influencing the overall decision to use of electronic payments. However, in specific payment contexts cognitive traits, such as mental accounting, fungibility bias, and habit, do mediate in determining the choice of payment method. We found robust evidence that a higher value of our personal income proxy is associated with a reduction in the intention to use electronic payments. All results are robust to alternative econometric specifications: multinomial logistic, ordered logistic, and logit regressions. Our research provides a clear policy message, namely for authorities to promote a variety of payment alternatives, including cash, and ensure they are available in retail transactions. |

| Abstract: | The paper focuses on two crucial aspects of the digital economy: digital platforms and digital transformation. These two topics play a significant role in shaping the modern business landscape and have implications across various industries. Digital platforms, along with the related digital platform economy, and digital transformation lead to innovative business models and strategies that capitalize on the vast potential of the digital economy. However, the paper points out that digital transformation is not just about technology; it's also about people, processes, and culture. |

| Abstract: | Tokenization is a process that may cause a transition to new monetary standards in a world of decentralized money. The possibility of tokenization explains why Bitcoin may have a high value today under expectations that the gradual decline in the mining reward will reduce security, as explained by Auer (2019). The paper introduces tokenization as a way to upgrade Bitcoin and discusses how the possibility of tokenization can affect the value of the first cryptocurrency. Tokenization may be deferred because of the balance between the network effect and congestion in the usage of Bitcoin’s blockchain against those for the new monetary standard. As security of Bitcoin declines, this balance shifts in favour of the new monetary standard. The new monetarist model predicts zero price of Bitcoin in the view of declining security and absence of the option for tokenization. Enabling agents to use tokenized version of Bitcoin instead of Bitcoin itself allows for an equilibrium in which the price of Bitcoin increases with time as the new monetary standard is adopted more widely. |

| Abstract: | We discuss the payment habits of Canadians both in the current payment environment and in a hypothetical cashless environment. We also consider whether a central bank digital currency (CBDC) would address unmet payment needs in a cashless society. Most adult Canadians do not experience gaps in their access to a range of payment methods, and this would probably continue to be the case in a cashless environment. Some people could, however, face difficulties making payments if merchants no longer generally accepted cash as a method of payment. For a payment-oriented CBDC to successfully address unmet payment needs, the main consumer groups—who already have access to a range of payment options—would have to widely adopt the CBDC and use it at scale. This is necessary to encourage widespread merchant acceptance of CBDC, which would, in turn, encourage further consumer adoption and use. However, most consumers face few payment gaps or frictions and therefore might have relatively weak incentives to adopt and—especially—to use CBDC at scale. If that were the case, widespread merchant acceptance also would be unlikely. This suggests that addressing unmet payment needs for a minority of consumers by issuing a CBDC could be challenging under the conditions explored in this paper. The minority of consumers with unmet payment needs will only be able to benefit from a CBDC if the majority of consumers experience material benefits and therefore drive its use. |

| Abstract: | We study the real economic activity in the Bitcoin blockchain that involves transactions from/to retail users rather than between organizations such as marketplaces, exchanges, or other services. We first introduce a heuristic method to classify Bitcoin players into three main categories: Frequent Receivers (FR), Neighbors of FR, and Others. We show that most real transactions involve Frequent Receivers, representing a small fraction of the total value exchanged according to the blockchain, but a significant fraction of all payments, raising concerns about the centralization of the Bitcoin ecosystem. We also conduct a weekly pattern analysis of activity, providing insights into the geographical location of Bitcoin users and allowing us to quantify the bias of a well-known dataset for actor identification. |

| Abstract: | Using repeated large-scale surveys of U.S. households, we study the cryptocurrency investment decisions and motives of households relative to other financial assets. Cryptocurrency holders tend to be young, white, male and more libertarian relative to non-crypto holders. They expect much higher rates of returns for crypto and perceive it as relatively safer than do other households. They also view it as a better hedge against inflation. For those holding cryptocurrencies, changes in Bitcoin prices translate into their purchases of durable goods. Finally, exogenously-provided information about historical returns of cryptocurrencies leads individuals to increase their desired crypto holdings and makes them more likely to actually purchase cryptocurrency subsequently. We compare these views and behaviors to those of households toward other financial assets and argue that cryptocurrency is unique in many of these respects. |

| Abstract: | Tokens are units digitally represented in a distributed ledger or blockchain. The various uses of this technology have the potential to transform a wide array of economic activities, from traditional commercial transactions to sophisticated financial undertakings. This paper explores the similarities and differences of tokens with traditional legal instruments in commercial law and how tokens could offer superior solutions, provided that proper legal foundations are established for their operation, including aspects of the law of securities and consumer protection law. |

| Abstract: | This research studies the online consumer experience and, more specifically, the role of design e-personalisation of e-commerce websites adapted to the needs of consumers with disabilities (perceptual, cognitive or physical). It examines the roles of ease of use and pleasure of use as explanatory mechanisms for the effects of design e-personalisation on e-commerce website reuse and positive word-of-mouth intentions. We propose an online consumer experience model based on perceived design e-personalisation and test it empirically with structural equations on a sample of 117 participants from a panel of French Internet users who are more than 55 years old and have disabilities. The results highlight a serial double mediation of design e-personalisation on reuse and word-of-mouth intentions via ease of use and pleasure of use. |

| Abstract: | Undoubtedly, the digital economy provides children with ample opportunities for growth and self-development. However, it also makes them more vulnerable to harm in the online as well as the offline world.12 With younger people going online with minimal adult supervision, children are at a higher risk of falling prey to dangers in the online space and making unfortunate choices without fully comprehending the consequences of their actions. Some of these risks include exposure to inappropriate content such as sexual, pornographic and violent images. Websites containing information related to dangerous behaviours such as self-harm, suicide and anorexia, or suffering reputational damage at the hands of cyber bullies or responding to unsafe contact from an adult such as online solicitation or grooming are other examples of potential risks. Constant digital connectivity has made children more accessible to predators through unprotected social media profiles and online game forums, making children even more vulnerable than before. this paper, an attempt has been made to discuss the legal frameworks and age verification requirements in various jurisdictions protecting minors in the digital economy. Thereafter, the requirements proposed in India's Personal Data Protection Bill 2018 will be discussed. This is followed by a section on various age-verification methods currently in place in various parts of the world and its associated implementation challenges. The paper concludes with a snapshot of sectoral variation and recommendations for further policy thinking on this subject. |

| Abstract: | Cryptocurrencies exhibit unique statistical and dynamic properties compared to those of traditional financial assets, making the study of their volatility crucial for portfolio managers and traders. We investigate the volatility connectedness dynamics of a representative set of eight major crypto assets. Methodologically, we decompose the measured volatility into positive and negative components and employ the time-varying parameters vector autoregression (TVP-VAR) framework to show distinct dynamics associated with market booms and downturns. The results suggest that crypto connectedness reflects important events and exhibits more variable and cyclical dynamics than those of traditional financial markets. Periods of extremely high or low connectedness are clearly linked to specific events in the crypto market and macroeconomic or monetary history. Furthermore, existing asymmetry from good and bad volatility indicates that information about market downturns spills over substantially faster than news about comparable market surges. Overall, the connectedness dynamics are predominantly driven by fundamental crypto factors, while the asymmetry measure also depends on macro factors such as the VIX index and the expected inflation. |

| Abstract: | Cryptocurrency trading represents a nascent field of research, with growing adoption in industry. Aided by its decentralised nature, many metrics describing cryptocurrencies are accessible with a simple Google search and update frequently, usually at least on a daily basis. This presents a promising opportunity for data-driven systematic trading research, where limited historical data can be augmented with additional features, such as hashrate or Google Trends. However, one question naturally arises: how to effectively select and process these features? In this paper, we introduce Multi-Factor Inception Networks (MFIN), an end-to-end framework for systematic trading with multiple assets and factors. MFINs extend Deep Inception Networks (DIN) to operate in a multi-factor context. Similar to DINs, MFIN models automatically learn features from returns data and output position sizes that optimise portfolio Sharpe ratio. Compared to a range of rule-based momentum and reversion strategies, MFINs learn an uncorrelated, higher-Sharpe strategy that is not captured by traditional, hand-crafted factors. In particular, MFIN models continue to achieve consistent returns over the most recent years (2022-2023), where traditional strategies and the wider cryptocurrency market have underperformed. |

| Abstract: | Do peers influence individuals’ involvement in political activism? To provide a quantitative answer, I study Argentina’s abortion rights debate through Twitter - the social media platform. Pro-choice and pro-life activists coexisted online, and the evidence suggests peer groups were not too polarized. I develop a model of strategic interactions in a network - allowing for heterogeneous peer effects. Next, I estimate peer effects and test whether online activism exhibits strategic substitutability or complementarity. I create a novel panel dataset - where links and actions are observable - by combining tweets’ and users’ information. I provide a reduced-form analysis by proposing a network-based instrumental variable. The results indicate strategic complementarity in online activism, both from aligned and opposing peers. Notably, the evidence suggests homophily in the formation of Twitter’s network, but it does not support the hypothesis of an echo-chamber effect. |

| Abstract: | The open availability of the entire history of the Bitcoin transactions opens up the possibility to study this system at an unprecedented level of detail. This contribution is devoted to the analysis of the mesoscale structural properties of the Bitcoin User Network (BUN), across its entire history (i.e. from 2009 to 2017). What emerges from our analysis is that the BUN is characterized by a core-periphery structure a deeper analysis of which reveals a certain degree of bow-tieness (i.e. the presence of a Strongly-Connected Component, an IN- and an OUT-component together with some tendrils attached to the IN-component). Interestingly, the evolution of the BUN structural organization experiences fluctuations that seem to be correlated with the presence of bubbles, i.e. periods of price surge and decline observed throughout the entire Bitcoin history: our results, thus, further confirm the interplay between structural quantities and price movements observed in previous analyses. |

| Abstract: | We examine the impact of digitalization on people’s perceptions of women as political leaders in 34 Sub-Saharan African countries. We find that being a social media or internet user is linked to a higher likelihood of people supporting gender equality in political leadership. However, the intensive margin of usage does not appear to be significant. Furthermore, women’s perceptions of gender equality in political leadership are more sensitive to internet and social media use than men’s. The paper recommends policies for improving ICT infrastructure and investing in technological education. |

| Abstract: | Written on the 50th anniversary of floating exchange rates, this paper deals with possible alternatives to a unipolar dollar-based system. It considers (1) measures of international currency use; (2) potential challengers to the dollar; (3) network externalities; and (4) the plausibility of gold and digital currencies, as alternatives to regular currencies. On the one hand, network externalities operate in favor of the status quo: the dollar as the single leading international currency. On the other hand, the danger of abuse of exorbitant privilege – for example, by debasing the currency or repeated use of sanctions – operates in favor of challengers. A good guess is that the dollar will continue to lose market share slowly to others, but will remain in the lead. |

| Abstract: | We conduct a randomized survey experiment to compare the short- and longer-term effects of fact checking to a brief media literacy intervention. We show that the impact of fact checking is limited to the corrected fake news, whereas media literacy helps to distinguish between false and correct information more generally, both immediately and two weeks after the intervention. A plausible mechanism is that media literacy enables participants to critically evaluate social media postings, while fact checking fails to enhance their skills. Our results promote media literacy as an effective tool to fight fake news, that is cheap, scalable, and easy-to-implement. |

| Abstract: | Human interactions create social networks forming the backbone of societies. Individuals adjust their opinions by exchanging information through social interactions. Two recurrent questions are whether social structures promote opinion polarisation or consensus in societies and whether polarisation can be avoided, particularly on social media. In this paper, we hypothesise that not only network structure but also the timings of social interactions regulate the emergence of opinion clusters. We devise a temporal version of the Deffuant opinion model where pairwise interactions follow temporal patterns and show that burstiness alone is sufficient to refrain from consensus and polarisation by promoting the reinforcement of local opinions. Individuals self-organise into a multi-partisan society due to network clustering, but the diversity of opinion clusters further increases with burstiness, particularly when individuals have low tolerance and prefer to adjust to similar peers. The emergent opinion landscape is well-balanced regarding clusters' size, with a small fraction of individuals converging to extreme opinions. We thus argue that polarisation is more likely to emerge in social media than offline social networks because of the relatively low social clustering observed online. Counter-intuitively, strengthening online social networks by increasing social redundancy may be a venue to reduce polarisation and promote opinion diversity. |

| Abstract: | This paper studies the effect of e-commerce on local labor markets. We exploit cross-market variation in e-commerce price advantage stemming from the enactment of the Amazon Tax-state-level legislation that mandates state sales taxes collection to out-of-state online retailers. Introducing out-of-state sales taxes lowered employment and reduced wages in transportation and warehousing, industries complementary to e-commerce. Within the in-state retail sector, the decline in brick-and-mortar employment is somewhat offset by an increase in employment in warehouse clubs and supercenters. Our results are consistent with a general equilibrium model in which consumers substitute e-commerce for big-box purchases, crowding out brick-and-mortar retail. |

| Abstract: | Training and deploying the large language models requires a large mount of computational resource because the language models contain billions of parameters and the text has thousands of tokens. Another problem is that the large language models are static. They are fixed after the training process. To tackle these issues, in this paper, we propose to train and deploy the dynamic large language model on blockchains, which have high computation performance and are distributed across a network of computers. A blockchain is a secure, decentralized, and transparent system that allows for the creation of a tamper-proof ledger for transactions without the need for intermediaries. The dynamic large language models can continuously learn from the user input after the training process. Our method provides a new way to develop the large language models and also sheds a light on the next generation artificial intelligence systems. |

| Abstract: | Technological change had a major impact on all sectors of activity, including banking, which is considered a pioneer in the adoption of new technologies. Over the past decade, the banking sector has always been at the forefront of technological development.Today, the digitalization of banking services is booming. Moroccan banks are increasingly focusing on technological solutions to deliver a better customer experience to banking customers. Mobile payment, being one of the most recent tools, remains, if not unrecognizable, rarely used, despite the many advantages it offers in terms of convenience, speed and security. The aim of our paper is to determine the factors that can influence this fact, through a presentation of the state of the art, in particular the concept of innovation, being a continuous process that aims to introduce new ideas, technologies, products or services, by relating the different theories and models of its adoption. Our main motivation lies in understanding the banking consumer's behavior towards mobile payment, as much as the modern solution proposed by Moroccan banks. Through this article, and by going through a set of theoretical models of innovation adoption, mobile payment in our case, we will deduce a conceptual model including factors that may possibly influence the use or intention to use the mobile payment tool by banking consumers and thus determine their implications. In future work, the hypotheses deduced will be tested using the structural equation method. |
| Abstract: | L'évolution technologique a eu un impact majeur sur les différents secteurs d'activité, notamment le secteur bancaire considéré comme pionnier en matière d'adoption des nouvelles technologies. Depuis une décennie, le domaine bancaire a toujours été en avance en matière de développement technologique. De nos jours, la digitalisation des services bancaires est en plein essor. Les banques marocaines se focalisent de plus en plus sur les solutions technologiques pour offrir une meilleure expérience client aux consommateurs bancaires. Le paiement mobile, étant un des outils les plus récents, demeure si ce n'est méconnaissable, peu utilisé, malgré les nombreux avantages qu'il propose en termes de praticité, rapidité et sécurité. L'objectif de notre papier est de déterminer les facteurs pouvant influencer ce fait, à travers une présentation d'un état de l'art, notamment du concept de l'innovation, étant un processus continu qui vise à introduire de nouvelles idées, technologies, produits ou services, en relatant les différentes théories et les différents modèles de son adoption. Notre motivation principale réside dans la compréhension du comportement du consommateur bancaire face au paiement mobile, autant que solution moderne proposée par les banques marocaines. À travers ce présent article, et en passant par un ensemble de modèles théoriques de l'adoption de l'innovation, dans notre cas, le paiement mobile, nous déduirons un modèle conceptuel comportant les facteurs pouvant éventuellement influencer l'utilisation ou l'intention d'utiliser l'outil du paiement mobile par les consommateurs bancaires et ainsi de déterminer leurs implications. Dans un futur travail, les hypothèses déduites seront testées à travers l'utilisation de la méthode des équations structurelles. |

| Abstract: | Using transaction data from a large non-fungible token (NFT) trading platform, this paper examines how the behavioral bias of selection-neglect interacts with extrapolative beliefs, accelerating the boom and delaying the crash in the recent NFT bubble. We show that the price-volume relationship is consistent with extrapolative beliefs about increasing prices which were plausibly triggered by a macroeconomic shock. We test the hypothesis that agents prone to selection-neglect formed even more optimistic beliefs and traded more aggressively than their counterparts during the boom. When liquidity for NFTs declined, observed NFT prices were subject to severe selection bias due in part to seller loss aversion delaying the onset of the crash. Finally, we show that market participants with sophisticated bidding behavior were less subject to selection bias and performed better. |

| Abstract: | Digital inclusion implies that individuals and communities can access and adopt technology to improve their socio-economic status. India, like most emerging markets, has benefitted immensely from the diffusion of Information and Communication Technology (ICT) diffusion. In rural areas, communication services can often compensate for other infrastructural deficits, catalysing growth. However, market failures in rural areas, magnified by poor connectivity and lack of digitalization, demand policy intervention. Following customary global practice, the Indian government, has made universal broadband a priority objective. |
