Usefulness of Netnography in the Digital Banking Context

This chapter discusses the usefulness of netnography as a research method in the digital banking context. Netnography has become a relative attractive data collection and data analysis method in some social science research areas but is still relatively unknown in financial research. Compared with other research methods, netnography seems to have some advantages in the digital banking world, such as real-time customer feedback. Moreover, virtual observations can be used not only by researchers but also by bank representatives to, for example, find out how bank customers can contribute to value co-creation.

Liquidity effects on oil volatility forecasting: From fintech perspective

Fin-tech is an emerging field, inspiring revolutionary innovations in the financial field. It may initiate the evolutionary episode of the financial research, where volatility forecasting is a crucial topic in finance. For forecasting volatility, GARCH model is a prevailing model, however, further improvement of the GARCH model is still challenging. In this paper, we demonstrate how Fintech can play a part in volatility forecasting by employing a metaheuristic procedure called Genetic Programming. On the basis, we are able to develop a new volatility forecasting model, which can beat GARCH family models (including GARCH, IGARCH and TGARCH models) in a significant way. Since genetic programming is an evolutionary algorithm based on the principles of natural selection, this innovative work will be a breakthrough point in the financial area. The innovation of this paper demonstrates how GP technology can be applied in the financial field, attempting to explore the volatility forecasting area from the combination of new technology and finance, known as fintech. More importantly, when the formula of volatility forecasting is unknown as we introduce a new factor, namely, the liquidity factor, we unveil that how GP method can be helpful in determining the specific volatility forecasting model format. We thereby exhibit the liquidity effects on volatility forecasting filed from the fintech perspective.

Review of the 151th meeting of the Dispute club “Economic Policy Knots” of the Association of the Russian Economic Think Tanks on the Topic “What is the Twenty-first year preparing for us?”

The work is devoted to a review of the results of the 151st meeting of the Dispute Club “Economic Policy Knots” of the Association of Russian Economic Think Tanks (hereinafter referred to as ARETT) on the topic "What is the twenty-first year preparing for us?" The purpose of the event was to discuss issues of economic and market development in 2021. The debaters were Alexei Leonidovich Vedev, head of the financial research laboratory of the Institute for Economic Policy named after E.T. Gaidai, and Natalia Vladimirovna Orlova, head of the “AO ALFA-BANK” macroeconomic analysis center. The review presents the key ideas of the disputants, and also summarizes the main results of their answers to questions.

Review Procedures Borrowing And Return Record Files Medical Outpatient Medical Record in Health Unit River Candle

The borrowing of medical record documents at the puskesmas is used for internal or external purposes which include needs in aspects of the usefulness of medical record documents such as administrative, medical, legal, financial, research, and educational aspects. Based on a survey at the puskesmas, the procedure for borrowing and returning medical record files has not been carried out effectively, for example, the return of outpatient medical record files is often not in accordance with the provisions, namely a maximum of 1 (one) hour before the end of working hours, thus hampering the implementation of medical record retrieval at any time. The time is needed by patients, doctors, and parties who need medical record files. The purpose of this study was to determine the procedure for borrowing and returning outpatient medical record files. This research is a type of descriptive research. The object of the research is the procedure for borrowing and returning medical record files of outpatients in the medical record unit. The instruments used are observation guidelines and interview guidelines.

Chaotic Dynamics Analysis Based on Financial Time Series

It is a common phenomenon in the field of financial research to study the dynamic of financial market and explore the complexity of financial system by using various complex scientific methods. In this paper, the chaotic dynamic properties of financial time series are analyzed. Firstly, the nonlinear characteristics of the data are discussed through the empirical analysis of agriculture index data; the daily agriculture index returns can be decomposed into the different scales based on wavelet analysis. Secondly, the dynamic system of some nonlinear characteristic data is established according to the Taylor series expansion form, and the corresponding dynamic characteristics are analyzed. Finally, the bifurcation diagram of the system shows complicated bifurcation phenomena, which provides a perspective for the analysis of chaotic phenomena of economic data.

Finite-Time Impulsive Control of Financial Risk Dynamic System with Chaotic Characteristics

The control of financial risk has always been one of the important topics in financial research. Based on the theory of finance, this paper proposes a kind of financial risk dynamic system. By analyzing some properties of the dynamic system, the system shows obvious coexisting chaotic oscillations. In order to control the financial risk dynamic system effectively, this paper proposes a finite-time impulse controller to control the financial risk dynamic system. Simulation results show that the finite-time impulse controller has faster convergence speed than the impulse controller.

Stress, Contagion, and Transmission: 2020 Financial Stability Conference

Once a year, financial system regulators and economists meet to present and discuss the latest research on financial stability at a conference sponsored by the Federal Reserve Bank of Cleveland and the Office of Financial Research. The major focus of discussion during the 2020 conference was the impact of the COVID-19 pandemic on the financial system. This Commentary summarizes the ideas and insights presented in the research papers and keynote speeches.
