Evidence of multifractality from emerging European stock markets.

Abstract: We test for the presence of multifractality in the daily returns of the three most important stock market indices from Central and Eastern Europe, Czech PX, Hungarian BUX and Polish WIG using the Empirical Mode Decomposition based Multifractal Detrended Fluctuation Analysis. We found that the global Hurst coefficient varies with the q coefficient and that there is multifractality evidenced through the multifractal spectrum. The exercise is replicated for the sample around the high volatility period corresponding to the last global financial crisis. Although no direct link has been found between the crisis and the multifractal spectrum, the crisis was found to influence the overall shape as quantified through the norm of the multifractal spectrum.

The impact of COVID-19 on consumer behavior in retail banking. Evidence from Romania

Abstract: The pandemic COVID-19 has severely affected the global economy. The strict lockdown measures have also changed the daily live, including consumer behavior in retail banking. In this context, the purpose of this paper is to investigate the impact of the COVID-19 crisis on consumer behavior in retail banking, with a special focus on the Romanian banking sector. To achieve our goal, we performed a survey among the Romanian consumers in retail banking, using as research method the field survey based on questionnaire. The final sample comprised 738 valid responses from the metropolitan area retail banking consumers. The research brings a fresh insight on retail banking services consumption during the pandemic and validates a conceptual model regarding the internet and mobile banking services acceptance. The research’ results highlighted, among others, that the variable concerning the perception of the COVID-19 pandemic effect on consumers’ lifestyle has a direct and positive influence on the variable regarding the attitude toward internet and mobile banking services, mediated by other variables like safety of internet and mobile banking use and trust in banks. Several social and managerial implications are also discussed, because it is possible that the tendency to use internet and mobile banking services will prevail even after the post pandemic stage, as new consumption behavior models are developing. Banks in Romania should increase their initiatives to offer financial education courses and online tutorials to familiarize customers with the use of digital channels. Banks should also improve communication with clients and design new products and services to increase the attractiveness of saving process. They should demonstrate flexibility in negotiating lending and refinancing conditions as well.

Surface dynamics in tin dioxide-containing catalysts II. Competition between water and oxygen adsorption on polycrystalline tin dioxide

Abstract: The interaction of polycrystalline tin dioxide with traces of water contained in argon or in oxygen during repeated temperature cycling between 20 and 400 °C has been followed by measuring in situ a.c. electrical conductivity and by thermogravimetry. In an ambient with residual humidity, water adsorption interferes with oxygen adsorption. The relative surface distribution of hydroxyl groups and oxygen species depends on the history of the sample.
