    The Relationship Between Energy Consumption and Economic Growth: Evidence From Different Income Country Groups
    (Econjournals, 2017) Yaşar, N.
    This study analyses the relationship between energy consumption and economic growth for 119 countries during the period of 1970-2015, classified into four groups regarding to the World Bank income ranking. The main motivation of this study is to analyze whether the causal relationship differs between different income groups of countries. For this purpose, panel auto regressive distributed lag boundary approach and Granger causality test were used. The results of the study indicate that the causal relationship between energy use and economic growth differs depending on which income group country belongs to. We conclude that the feedback hypothesis is supported for upper-middle income group in the long run and high-income group, while conservation hypothesis is supported for upper-middle income group in the short run and lower-middle income group in the long run. Finally, neutrality hypothesis is supported for low and lower middle-income groups in the short run. © 2017, Econjournals. All rights reserved.

    Firm Survival in Times of Crisis: Do Innovation and Financing Constraints Matter? Insights From the Covid-19 Pandemic
    (Routledge Journals, Taylor & Francis Ltd, 2023) Ozsuca, Ekin Ayse
    Utilizing survey data collected over three rounds, this paper investigates the impact of pre-COVID innovation performance, innovation type, sources of knowledge, and the moderating role of financial constraints on survival following the outbreak of COVID-19. The findings pinpoint a strong and positive link between firm survival and innovation, especially process innovation, confirming the ability of innovators to adapt to new conditions as a determinant of survival. Moreover, relying on internal knowledge is found to increase the chance of survival and adaptability to times of crisis. The results further indicate that access to finance strengthens the positive impact of innovation on firm survival/adaptation.

    The Stochastic Futures of the Natural Gas Prices: Russian Federation in Caspian Region
    (2014) Yaşar Başkaraağaç, Nermin
    This study examines the convergence hypothesis of natural gas price series of Russian Federation and USA using both linear and nonlinear time series techniques Russian Federation and USA during the period of 1991-2011. Although the linear Augmented Dickey Fuller (ADF), Philips Perron (PP), test provide evidence of the existence of a unit root, which means that the series are nonstationary, KPSS test result support the null hypothesis of existence of the stationary series. A nonlinear test as an alternative approach to investigate whether there are nonlinearities in the series is also taken into consideration. KSS, the nonlinear testing procedure provide some supportive evidence of a nonlinear price convergence among the Russian Federation and USA.

    Ethical İssues İn Marketing: An Application For Understanding Ethical Decision Making
    (2014) Parıltı, Nurettin; Külter Demirgüneş, Banu; Özsaçmacı, Bülent
    In recent years business ethics and social responsibility have gained great importance in marketing practices, especially in societal marketing practices. Businesses infinitely struggle to indicate their contributions to society. Consumers consciously evaluate this contribution. Manipulated consumer choices and unethical marketing applications can affect purchasing behavior. Particularly intense competition, globalization and societal consciousness transform businesses into social organizations and lead them into marketing efforts offering social value. Although business ethics and social responsibility of businesses have gained more attention in recent years, defining consumers’ perceptions on ethical issues is still minimal. This study presents an empirical research of consumer perceptions on ethical issues. Reflection of this perception on purchasing behavior is also another important issue to be considered. The aim of this study is to investigate the factors related with ethical issues in marketing practices and to reveal possible influences of these factors on consumers’ ethical decision making. The main objective of the study is to find out consumers’ perceptions on businesses’ ethical issues such as misleading advertising, deceptive packaging and to reveal the impact of these issues on their ethical purchasing behavior or ethical decision making. It also reveals which criteria is more important for ethical decision making. This study reveals that consumers reflect their ethical perceptions on their purchasing behavior. Each ethical issue has been found to be a positive effect on purchasing behavior. Businesses’ practices on packaging has been indicated as the most effective ethical issue on purchasing behavior. The study is considered to be a significant outcome for businesses to direct their advertising, packaging and other activities.

    Stochastic Pattern of Health Care Spending: Evidence From Nonlinear Panel Data Analysis
    (Better Advances Press, 2021) Yasar, N.
    This paper analyses the stochastic pattern of health care spending for 188 countries around the world which are categorized into four groups based on the World Bank income categories. The main motivation of this ar-ticle is to evaluate whether the stochastic features of total health care expenditure varies if decomposed into private and public health care consumption. To achieve this goal, in addition to conventional empirical methods, latterly de-veloped panel stationarity approaches are employed for both linear and nonlinear regression processes. Our results demonstrate that allowing for cross-section dependency between series and nonlinearity in the estimation process may lead to more often rejection of the null hypothesis of unit root for all series in panel data set. © 2021 Better Advances Press.

    Is There a Financial Accelerator Mechanism in the Turkish Banking Industry
    (2018) Erenoğlu, Ekin Ayşe Özşuca
    This paper empirically investigates the cyclical behavior of price-cost marginsfor Turkish banks over the 2002q1-2017q3 period by exploiting dynamic panel datamodeling approaches. The estimation results indicate that margins behavecountercyclically during economic fluctuations. It appears that Turkish banks’ price-costmargins tend to stay high acting countercyclical during economic downturns, which maylimit the supply of loans and thereby, cause a further reduction in production, deepeningthe contraction. Specifically, several bank-specific characteristics, that is; banks’liquidity, capitalization and size, together with the monetary policy and marketconcentration in the banking industry are found to be crucial in explaining thecountercyclical behavior of net interest margins in Turkey. Furthermore, the recentglobal financial crisis in the late 2008 seems to have a considerable effect on the banksmargins as well. Overall, these findings provide evidence for the existence of “financialaccelerator” at work in the Turkish economy during the period under investigation.

    Insights into Consumer Preference of Foreign Brand Names: Reality or Myth?
    (2014) Akagün Ergin, Elif; Özsaçmacı, Bülent
    This study builds from LeClerc et al.’s (1989, 1994) work on foreign branding effects, but it does so in the context of a developing East European country; as in the case of Turkey. The purpose of this exploratory research is to examine consumers’ attitudes towards products with foreign brand names and also to assess the impact of foreign brand names on the purchasing decision making. In the data collection phase of the study an in-depth interviews were conducted with 23 participants in the city of Ankara, Turkey. The results show that products with foreign brand names elicit more positive consumer attitude than products with national brands. Overall, the findings suggest that consumers prefer to purchase products with foreign brand names for a variety of reasons which including quality, reliability, functionality and prestige. The results have important implications for domestic and foreign manufacturers with regards to the consumer-side effects of their decisions on branding strategies and on their competitive foreign branding decisions.

    Impact of Loyalty Cards On Customers’ Store Loyalty
    (2007) Akagün Ergin, Elif; Parıltı, Nurettin; Özsaçmacı, Bülent
    In this paper, we try to determine whether loyalty cards issued by stores have an impact on customer loyalty and how loyalty cards compare with other factors companies can use to increase loyalty in general. Based on the results of the study, it is concluded that loyalty cards have no impact on customers’s store loyalty. On the contrary, it is observed that customers that use their loyalty cards frequently tend to shop at different stores with different loyalty cards.

    Can Us Wage Increases Be Regarded as A\rleading Indicator for Bond Rates
    (2020) Acar, Elif Oznur; Özşuca, Ekin Ayşe
    After the subprime meltdown, the Federal Reserve focused its attention on US non-\rfarm payroll data in order to pave the way for its fund rate hikes. As time went by,\rthe Federal Reserve deemed particularly one sub-component of this data, namely the\rincrements on average weekly wage growth as a proxy for in\ration and thus a plausible\rexplanation for raising the interest rates. In that aspect, we decide to elaborate on this\rissue further and examine whether this implemented strategy indeed had a re\rection in\rthe real market. For doing so, we intend to determine whether there is any causality\rrelation in either direction between US average weekly wage increases and 10-year\rTreasury Bond rates. We utilize the Toda-Yamamoto causality approach and come\rup with a statistically signicant result between wages and bond rates. For robustness,\rwe also consider the unemployment rate and consumption expenditures as independent\rvariables.

    The Relationship Between Foreign Direct Investment and Co 2 Emissions Across a Panel of Countries
    (Springer International Publishing, 2018) Yaşar, N.; Telatar, M.E.
    This paper analyses the relationship between foreign direct investment inflows and pollution emissions for 139 countries during the period of 1970-2015 and the countries are classified into four groups regarding to the World Bank income ranking. The main motivation of this study is to analyse, whether the causal relationship differs between different income groups. For this purpose, panel ARDL (Auto Regressive Distributed Lag) boundary approach and Granger causality test are used. The results of the study indicate that the causal relationship between FDI (Foreign Direct Investment) and CO 2 emissions differs depending on which income group country belongs to. We conclude that, while there is not statistically significant short-run causality relationship running from FDI to CO 2 emission for high income, upper middle income and low income group countries, the pollution haven hypothesis is supported for lower middle income group countries. © Springer International Publishing AG, part of Springer Nature 2018.
