    Does Internet Use Affect Air Pollution? Evidence from OECD Countries
    (Econjournals, 2024) Kurt, Unzule; Kilic, Cuneyt; Akcan, Ahmet Tayfur
    This study aims to analyze the relationship between the use of the internet, which has an important place in information and communication, and air pollution (Carbon Dioxide Emissions-CO2). In this context, the relationship between the variables for the 1994-2019 period in 28 OECD countries selected was tested with the help of a panel data analysis with Fourier functions (Fourier unit root test, panel Fourier cointegration test and panel Fourier causality test). The results of the analysis show that internet use reduces air pollution, while economic growth increases air pollution. The results of the Panel Fourier Granger Causality test revealed a bidirectional causality relationship between internet use and air pollution and a unidirectional causality relationship from air pollution to economic growth throughout the panel. The analysis results present a policy proposal to the governments of OECD countries that they can reduce air pollution by investing in information and communication technologies (ICT) in their economic growth processes. © 2024, Econjournals.

    The Concept of Expectation in Behavioral Finance Theory: A Bibliometric Analysis
    (World Scientific and Engineering Academy and Society, 2025) Kurt, Unzule; Çalışkan, Zehra Doğan
    Behavioral economics is a subfield of economics that reveals how individuals' economic decisions are influenced by cognitive, emotional, and psychological factors. In behavioral economics, individuals are not only seen as actors who interpret economic indicators and make rational decisions but they are also considered in terms of their emotions and motivations. Therefore, behavioral economics investigates how certain emotional and psychological motivations affect economic decisions. Behavioral finance theory, from the same perspective, examines the financial decisions individuals make within the context of psychological and emotional variables. In behavioral finance theory, the most important emotional determinant is the concept of "expectation." In this context, the study investigates how the concept of "expectation" is addressed in studies examining the field of behavioral finance theory using the bibliometric analysis method. This research examines databases such as Web of Science, Scopus, and Google Scholar between the years 1985-2022, based on criteria such as the number of publications, citations, leading authors, countries, and institutions, aiming to reveal the evolution of the concept of expectation over time. In this regard, the study finds that the effects of the concept of expectation in behavioral finance theory have been examined more frequently since the 2000s. These studies primarily focus on risk perception and loss aversion behaviors. © 2025, World Scientific and Engineering Academy and Society. All rights reserved.
