    Abstract: Smart sustainable development and inclusive growth policy in Europe have a significant social impact on the cities and regions. The investigation of the regions’ potential is a starting point for the social and economic development that leads to a higher quality of life. Together with developed smart infrastructures such as Industry 4.0, smart transport and cities have to be hospitable for people with disabilities. This concept is based on the combination of digital, economic, social, environmental, and other structures. Nowadays, digital technologies simplify the everyday activities of the blind and visually impaired (B&VI) people, their employment, and make the work conditions more B&VI friendly. The real estate facilities were drastically changed for the B&VI last decade. Internet of Things helps the B&VI to increase control over their lives and live independently. Examples of today available assistive devices are as follows: related to low vision (magnifiers; near/distance vision telescopes), for daily living (thermometers, barometers, and other meteorological sensors; lighting; color sensors; liquid level indicators; money handling devices), for information and communication (mobile communications; screen magnification software; Braille editing and translation software; web-browsers for non-visual output; computer vision), automatic doors and windows (smart locks; smart doorbells; smart curtains and shades), voice assistants (music and audiobooks; heating control; voice-activated phone calls; news and weather updates; calendars and reminders), home help (garden robots; robot hoovers). However, the standard smart assistive infrastructures have not been developed yet. The most prospect approach is the combination of the real estate facilities/services with the B&VI assistive soft-/hardware at the construction and facility management stage including related laws and standards.This paper discusses how the ICT technologies simplify the B&VI everyday activities and employment and make their work and living conditions in buildings more B&VI friendly and how it can influence on a real estate market and regional development. Even a small success rate implies a large socio-economic territorial benefit.

    Abstract: The spread of distributed ledger technology (DLT) in finance could help to improve the efficiency and quality of supervision. This paper makes the case for embedded supervision, ie a regulatory framework that provides for compliance in tokenised markets to be automatically monitored by reading the market's ledger, thus reducing the need for firms to actively collect, verify and deliver data. After sketching out a design for such schemes, the paper explores the conditions under which distributed ledger data might be used to monitor compliance. To this end, a decentralised market is modelled that replaces today's intermediary-based verification of legal data with blockchain-enabled data credibility based on economic consensus. The key results set out the conditions under which the market's economic consensus would be strong enough to guarantee that transactions are economically final, so that supervisors can trust the distributed ledger's data. The paper concludes with a discussion of the legislative and operational requirements that would promote low-cost supervision and a level playing field for small and large firms.

    Abstract: In the economic literature, a medium of payment has two properties: liquidity and store of value. The fast and increasing development of digital currencies raises the question: is privacy a third attribute? We test these assertions through a laboratory experiment. From the theoretical viewpoint, the experiment relies on the simultaneous combination of Keynes’s traditional demand for money and Friedman’s forward looking intuition on the role of privacy. Results show that privacy positively matters and increases the overall appeal of a medium of payment, even more for risk prone individuals. Given privacy, the sacrifice ratio between liquidity risk and opportunity cost is relatively high. Within the current debate, the experiment suggests that the future competition between alternative currencies will depend on how the three properties will be mixed in a way consistent with the individual’s preferences.

    Abstract: Mobile money is a financial innovation that provides transfers, payments, and other financial services at a low or zero cost to individuals in developing countries where banking and capital markets are deficient and financial inclusion is low. We use transaction costs and institutional theories to explain the growth and impact of mobile money. Having developed a new archival dataset that tracks mobile money deployment across 90 emerging economies during 16 years between 2000 and 2015, we address the question of relative economic impact of the banking and telecoms sectors in the provision of mobile money. We show that telecom groups and not banks are more likely to launch mobile money in countries where legal rights are weaker and credit information less prevalent. However, it is when mobile money is offered via a banking channel that the spillover effects on the economy are greater. Findings have significant implications for policy and strategy.

    Abstract: We offer an overlapping generations equilibrium model of cryptocurrency pricing and confront it to new data on bitcoin transactional benefits and costs. The model emphasizes that the fundamental value of the cryptocurrency is the stream of net transactional benefits it will provide, which depend on its future prices. The link between future and present prices implies that returns can exhibit large volatility unrelated to fundamentals. We construct an index measuring the ease with which bitcoins can be used to purchase goods and services, and we also measure costs incurred by bitcoin owners. Consistent with the model, estimated transactional net benefits explain a statistically significant fraction of bitcoin returns.

    Abstract: The development of digital technologies that helped to integrate internet into every home has changed the world. This includes the opportunity to work online at home (e-office), to shop online (e-shops), or the possibility of renting your own home (e.g. Airbnb). Thereby, the digitalization factor has brought new challenges to property market, e.g., promoting working from home model decreases demand of office units; increasing online shopping reduces demand of retail units and increases demand for industrial units such like warehouses. According to Gartner, the digitalization is the use of digital technologies to change a business model and provide new revenue and value-producing opportunities; and it is the process of moving into a digital business (Gartner, 2019). The digitalization factor represents an impact of internet technologies on property market. The aim of this study was to examine the digitalization factor and its impact on residential property market dynamics in Sweden and the UK. The dynamics of residential property market have been analyzed by using both, quantitative and qualitative, data though application of narrative analysis and descriptive statistics. The data have been collected from the property and statistical databases, the academic literature, electronic sources, magazines and professional property market reviews. The research findings demonstrated that there is correlation between the digitalization factor and residential property market dynamics in both case study countries. However, the impact of digitalization factor on the residential property market dynamics variates in each case study country.

    Abstract: Existing blockchain protocols based on the proof-of-work consensus mechanism, such as Bitcoin, necessarily feature a time lag of roughly one hour before users can ``trust'' the information on the blockchain. In Bitcoin, this lag results in a settlement lag before parties are willing to exchange real goods and services in exchange for tokens. The time delay plays a key role in securing the data on the blockchain from malicious attacks or those attempting to overwrite the history of the data. However, this time delay is not sufficient to secure the data from attacks when the value of transactions supported by the blockchain becomes sufficiently large. In this paper, we show how the settlement lag may be used to develop a new consensus mechanism which significantly improves the security of blockchain data and, in some cases, eliminates theoretical limitations on the economic value of transactions supported by blockchains. We further demonstrate how to optimize the settlement lag to maintain security while ensuring the usefulness of the blockchain to facilitate transactional services.

    Abstract: The study sought to examine the contribution of Information and Communication Technology (ICT) on performance of banks in terms of service delivery in financial institutions in Ghana. The high competition in the Ghanaian banking industry has forced rapid changes as a result of technological innovation, increased awareness and demands from customers. The study adopted both exploratory and descriptive research design. Qualitative research method was used in collecting data and data was analyzed qualitatively. The main instrument for collecting data was the structured questionnaire. A sample size of 50 respondents consisting of 8 staff members and 48 customers of Barclays Bank was used for the study. A structured questionnaire was the main data collection instrument. The purposive and systematic sampling techniques were used to obtain the required sample size. The main tool which was used for the data analysis was Statistical Package for Social Sciences. Frequencies and percentages were used to present the data in a tabular form. The limitation affecting the study was time and financial constraints. The study revealed that ICT has an appreciable positive effect on performance due to improved customer service delivery. This affects the growth of Barclays Bank. ATM service flaws such as withdrawal discrepancies, issuance of faulty cards and long time for applied ATM cards to arrive deter most customers from accessing the service. Following from this study, it is recommended, Barclays Bank enhances the performance of their ATMs and their networks to increase customers satisfaction.

    Abstract: To minimize risks and increase transparency, every company needs reliable information. The quality and completeness of digital building documentation is more and more a factor as “deal maker” and “deal breaker” in real estate transactions. However, there is a fundamental lack of instruments for leveraging internal data and a risk of overlooking the essentials.In real estate transactions, the parties generally have just a few weeks for due diligence (DD). A large variety of Documents needs to be elaborately prepared and make available in data rooms. As a result, gaps in the documentation may remain hidden and can only be identified with great effort. Missing documents may result in high purchase price discounts. Therefore, investors are increasingly using a data-driven approach to gain essential knowledge in transaction processes. Digital technologies in due diligence processes should help to reduce existing information asymmetries and sustain data-supported decisions.The paper describes an approach to automate Due Diligence processes with a focus on Technical Due Diligence (TDD) using Machine Learning (ML), esp. Information Extraction. The overall aim is to extract relevant information from building-related documents to generate a semi-automated report on the structural (and environmental) condition of properties.The contribution examines due diligence reports on more than twenty office and retail properties. More than ten different companies generated the reports between 2006 and 2016. The research work provides a standardized TDD reporting structure which will be of relevance for both research and practice. To define relevant information for the report, document classes are reviewed and contained data prioritized. Based on this, various document classes are analyzed and relevant text passages are segmented. A framework is developed to extract data from the documents, store it and provide it in a standardized form. Moreover the current use of Machine Learning in DD processes, the research method and framework used for the automation of TDD and its potential benefits for transactions and risk management are presented.

    Abstract: This paper provides a systematic evaluation of the different types of digital currencies. We express skepticism regarding centralized digital currencies and therefore focus our economic analysis on private digital currencies. Specifically, we highlight the potential for private digital currencies to improve welfare within an emerging market with a selfish government. In that setting, we demonstrate that a private digital currency not only improves citizen welfare but also encourages local investment and enhances government welfare.

    Abstract: This paper studies the forecasting ability of cryptocurrency time series. This study is about the four most capitalized cryptocurrencies: Bitcoin, Ethereum, Litecoin and Ripple. Different Bayesian models are compared, including models with constant and time-varying volatility, such as stochastic volatility and GARCH. Moreover, some crypto-predictors are included in the analysis, such as S\&P 500 and Nikkei 225. In this paper the results show that stochastic volatility is significantly outperforming the benchmark of VAR in both point and density forecasting. Using a different type of distribution, for the errors of the stochastic volatility the student-t distribution came out to be outperforming the standard normal approach.

    Abstract: Blockchain might be the future of digitalizing assets into small pieces called tokens, of which the process is called tokenization. Transaction costs and speed are reduced, and entering into so called Real Estate Investment Trusts for investing in real estate are no longer an issue. Through tokenization, anyone from this planet can invest in real estate.Context: According to Savills (2017), the total value of world real estate reached $217 trillion in 2015. It only includes developed real estate and could have been much larger when we had counted the vast amount of non-developed land on the planet. One major boundary is the accessibility and the tradability of money. In the current situation, real estate is traded via Real Estate Investment Trusts (short: REITs). The problem with these REITs is the accessibility. Only the few people who can investment above the threshold can invest in real estate. Thereby, currency is another problem, because potential investors in Hong Kong cannot invest in Dutch real estate. This leads to a lack of liquidity on the financial real estate market. Blockchain might be the solution to this lack of global liquidity in real estate. In this way, real estate is purchased via smart contracts, traded via blockchain, and invested in by tokens: all very quickly. In this way, the world has no longer the financial borders from today. In theory, anyone can invest in real estate and make profit.The main question of this research paper is: In what way can tokenizing real estate by blockchain substitute the conventional way of investing in non-listed real estate?The sub questions of this theoretical framework in order to answer the main question are:What is the conventional way of trading non-listed real estate? How does this work? What are its boundaries? What is blockchain? How can it be adopted in real estate? What are smart contracts? What are its (dis)advantages? What is tokenization? How does it work? What are its (dis)advantages? What form of token is important in relation to tokenizing real estate successfully? What are the (legal) hurdles of tokenizing assets? What is the perspective of tokenization?

    Abstract: The prevalence of consumers sharing their purchases on social media platforms (e.g., Instagram, and Pinterest) and the use of this information by potential future consumers have substantial implications for online retailing. In this study, we examine how product characteristics and the type of information provider jointly moderate the purchase decision in a social network setting. We first propose an analytical observational learning framework integrating the impact of product differentiation and social ties. Then, we use two experimental studies to validate our analytical results and provide additional insights. Our key findings are that the effect of learning from strangers is stronger for vertically differentiated products than for horizontally differentiated products. However, the effect of learning from friends does not depend on whether the underlying product is horizontally or vertically differentiated. What is more interesting is the nuanced role of social ties: For horizontally differentiated products, the effect of learning increases with the strength of social ties. In addition, “contact-based” tie strength is more important than “structure-based” tie strength in accelerating observational learning. These findings provide a motivation for online retailers to generate alternative strategies for increasing product sales through social networks. For example, online retailers offering horizontally differentiated products have strong incentives to cooperate with social media platforms (e.g., Instagram and Pinterest) in encouraging customers to share their purchase information.

    Abstract: The author develops a dynamic model with two types of electronic money: reserves for transactions between bankers and zero-maturity deposits for transactions in the non-bank private sector. Using this model, he assesses the efficacy of unconventional monetary policy since the Great Recession. After quantitative easing, keeping the interest on reserves near zero too long might create deflation. The central bank can safely get out of the "low rate-cum-deflation" trap by "raising rate and raising money supply".

    Abstract: Modern era of management has seen a rise in the level of customer engagement, which was not that much of importance earlier. Earlier, brands tend to compete on the products or service they offer. In the recent digital era, it is much more than what a brand has to offer. The emergence of digital media has boosted the importance of customer engagement. Now, customers can easily get in touch with the companies through digital channels. Corporations use these channels to let customers aware about their offerings, ask for suggestions and recommendations, and solve the queries of the customers. This research is focus on ascertaining the relationship between customer engagement, customer satisfaction, and customer loyalty, and to identify how these factors impacts the repeat purchases in telecommunication sector. The research is based on descriptive research design; quantitative research design was trailed for questionnaire developing 5-point Likert scale technique.

    Abstract: The present technological revolution, characterized by the pervasive and growing presence of robots, automation, Artificial Intelligence and machine learning, is going to transform societies and economic systems. However, this is not the first technological revolution humankind has been facing, but it is probably the very first one with such an accelerated diffusion pace involving all the industrial sectors. Studying its mechanisms and consequences (will the world turn into a jobless society or not?), mainly considering the labor market dynamics, is a crucial matter. This paper aims at providing an updated picture of main empirical evidence on the relationship between new technologies and employment both in terms of overall consequences on the number of employees, tasks required, and wage/inequality effect.

    Abstract: Data rooms are becoming more and more important for the real estate industry. They permit the creation of protected areas in which a variety of relevant documents are typically made available to interested parties. In addition to supporting purchase and sales processes, they are used primarily in larger construction projects.The structures and index designations of data rooms have not yet been uniformly regulated on an international basis. Data room indices are created based on different types of approaches and thus the indices also diverge in terms of their depth of detail as well as in the range of topics. In practice, rules already exist for structuring documentation for individual phases, as well as for transferring data between these phases. Since all of the documentation must be transferable when changing to another life cycle phase or participant, the information must always be clearly identified and structured in order to enable the protection, access and administration of this information at all times. This poses a challenge for companies because the documents are subject to several rounds of restructuring during their life cycle, which are not only costly, but also always entail the risk of data loss. The goal of current research is therefore a seamless storage as well as a permanent and unambiguous classification of the documents over the individual life cycle phases.In the field of text classification, machine learning offers considerable potential in the sense of reduced workload, process acceleration and quality improvement. In data rooms, machine learning (in particular document classification) is used to automatically classify the documents contained in the data room or the documents to be imported and assign them to a suitable index point. In this manner, a document is always classified in the class to which it belongs with the greatest probability (ex: due to word frequency). An essential prerequisite for the success of machine learning for document classification is the quality of the document classes as well as the training data. When defining the document classes, it must be guaranteed on the one hand that these do not overlap in terms of their content, so that it is possible to clearly allocate the documents thematically. On the other hand, it must also be possible to consider documents that may appear later and be able to scale the model according to the requirements. For the training and test set, as well as for the documents to be analyzed later, the quality of the respective documents and their readability are also decisive factors. In order to effectively analyze the documents, the content must also be standardized and it must be possible to remove non-relevant content in advance.Based on the empirical analysis of 8,965 digital documents of fourteen properties from eight different owners, the paper presents a model with more than 1,300 document classes as a basis for an automated structuring and migration of documents in the life cycle of real estate. To validate these classes, machine learning algorithms were learned and analyzed to determine under which conditions and how the highest possible accuracy of classification can be achieved. Stemmer and stop word lists used specifically for these analyses were also developed for this purpose. Using these lists, the accuracy of a classification is further increased by machine learning, since they were specifically aligned to terms used in the real estate industry.The paper also shows which aspects have to be taken into account at an early stage when digitizing extensive data/document inventories, since automation using machine learning can only be as good as the quality, legibility and interpretability of the data allow.

    Abstract: This paper examines whether fear of robots is correlated with life satisfaction. After controlling for individual effects and country effects and using both standard ordinary least squares and a linear multilevel regression model we find fear of robots correlates with lower reported life satisfaction. There are differences in the fear of robots and life satisfaction by age group, by how long countries have been members of the European Union and by whether we control for attitudes towards other things. We call for more research into attitudes towards technology and new technologies in particular, how these impact on current life satisfaction and other aspects of quality of life and to think more about how technological change and people’s attitudes towards these can be more aligned.

    Abstract: The growth of online platforms has raised questions about their power and the possibility that it could be exercised with bias, including by gender. Women account for about a fifth of the most successful artists at Spotify, prompting some concerns about bias. We explore the roles of female participation, along with promotion decisions at the platform - in particular playlist inclusion - in explaining the female share of successful songs and artists at Spotify in 2017. We employ two broad tests for gender bias. First, we ask whether songs by female artists are differently likely to appear on global playlists, conditional on the past success of the artists, song characteristics such as genre, and gender. Second, we test for bias in New Music Friday playlist ranking decision based on outcomes, asking whether songs by female artists stream more, conditional on their New Music Friday rankings. We find some evidence consistent with bias (in favor of women at Today's Top Hits as well as in the New Music rankings, and against women at some global playlists). These biases, however, do little to explain the low female share of streaming on Spotify, which we instead attribute to the relatively low share of female songs entering the platform.
