Tao Yin, Yiming Wang

Since it was proposed by Satoshi Nakamoto (2008) at the end of 2008, Bitcoin, as an alternative to conventional currencies, has quickly gained wide attention from the media, investors and scholars. This attention is attributed to its transparency, simplicity, increasing popularity, decentralized peer-to-peer system and self-regulation. There is a growing interest in studying the general dynamics of Bitcoin market. For instance, diversification was measured (Brière et al., 2015; Bouri et al., 2017; Urquhart & Zhang, 2019; Chaim & Laurini, 2018; Lahmiri et al., 2018), statistical properties and market efficiency were examined (Bariviera et al., 2017; Carbone et al., 2004; Martinez et al., 2018; McCarthy, 2009; Symitsi & Chalvatzis, 2018), liquidity and microstructure were explored (Koutmos, 2018; Dyhrberg et al., 2018; Donier & Bonart, 2015), speculative bubble and risk were investigated (Osterrieder & Lorenz, 2017; Bouoiyour et al., 2015; Klein et al., 2018), regulation was studied (Dwyer, 2015; Tasca & Liu, 2018; Katsiampa, 2017) whilst optimal trading was scrutinized (Ajaz & Kumar, 2018; Li & Tourin, 2016; Yi et al., 2018).

The development and innovations of technology has paved the way for the expanding growth of an innovative form of commerce based on a principle of shared access of assets or resources rather than private ownership (Basukie et al., 2020).

INNOVATIVE ACTIVITY OF RESTAURANTS OPERATING IN THE LARGEST POLISH CITIES

Andrzej Rapacz, Piotr Gryszel, Marek Walesiak, Andrzej Dudek

The interaction of two phenomena is observed in well-developed countries, i.e. the growing importance of the service sector (transition to the service economy or the post-industrial society) and the increasing importance of knowledge, manifested in the creation of innovations (knowledge-based economy). We live in an era when the skills of acquiring and processing information as well as creating innovations remain the key factor responsible for the market success of businesses. As indicated by Škare and Tomić (2014), the market position of enterprises, their further development and prosperity largely depend on their opening towards innovations (Burns & Stalker, 1961; Weerawardena & Mavondo, 2011; Baily et al., 2006; Sandvik et al., 2014). The very idea of innovation was actually born in industry, however, the transition of the economic system to the one where services play a dominant or at least an equal role, resulted in the phenomenon of innovation spreading in the service sector as well (Schumpeter, 1934; Swann, 2009; Hjalager, 2010).

Romina Cheraghalizadeh, Jaroslava Dědková

The hotel industry has turned out to be one of the most competitive industries in the world. The competition among hotels forced them to increase the quality of services and improve the relationship with customers. Today business development is fast (Wijaya et al., 2021), and hotels require to deal with ongoing monitoring across a variety of service areas in order to improve the services at the best levels. The service quality is known as a fundamental determinant in differentiating service providers (Mey et al., 2006). It is an important element in customers’ initial decision-making, and their return intention. However, in today’s business world, hotels may face major challenges, such as frequent changes in customers’ preferences, and demands that are more complex. Therefore, there is room for this question of whether the perceived service quality is a sufficient stimulant to retain a relationship in a long term?

COVID-19 AND DIVIDENDS: EVIDENCE FROM POLAND

Kamil Gemra, Piotr Kwestarz, Waldemar Rogowski, Mariusz Lipski

In March 2020, we witnessed enormous turbulence in the global markets caused by the escalation of problems related to the new medical phenomenon of coronavirus (COVID-19) pandemic. High fluctuations of indices were observed during the pandemic, but the crisis caused by fighting the virus was also reflected in firms’ essentials. The uncertainty provoked by the pandemic in the real economy also influenced listed companies. Some of them were forced to restrict or cease their operations temporarily. One of the impacts that this caused relatively quickly was on dividend decisions. Listed companies that had paid dividends for many years faced a difficult decision on whether they should still pay them or instead restrict or cease issuing dividends. The purpose of such actions would be to build a capital and liquidity buffer.
