The population of the research was 6745 people working in the electronics and optics sector in Ankara Organized Industrial Zones and 464 people were sampled from the study. Regression equation results reveal that emotional intelligence has a positive effect on work performance, emotional intelligence affects the job satisfaction of individuals, and it is decisive upon life satisfaction resulting in the total satisfaction of individuals. However, cognitive intelligence (IQ) alone does not affect employee performance. Consequently, high levels of emotional intelligence of individuals also positively affect their social life, job satisfaction and performance. Therefore, the results are supported by the scope of this thesis, domino effect of business satisfaction, employee performance, operating efficiency, business world and country prosperity.</p> 2021-08-26T00:00:00+00:00 Copyright (c) 2020 Journal of Sustainable Economics and Management Studies https://dergiler.gelisim.edu.tr/index.php/ecoman/article/view/1 Testing Explosive Bubble for Eurozone Exchange Rate in the COVID-19 Outbreak: Evidence from Recursive Right-Tailed Tests 2020-12-18T22:10:52+00:00 Onur ÖZDEMİR onozdemir@gelisim.edu.tr <p>This paper investigates the presence of explosive bubbles in financial markets using daily data (5-day weeks) of the closing rate of EUR/USD exchange in the COVID-19 outbreak, covering the period from December 2, 2019 to December 4, 2020. The bubble behavior in the closing rate of EUR/USD exchange is measured by two distinct right-tailed testing procedures. In this vein, the Supremum Augmented Dickey-Fuller (SADF) test developed by Phillips et al. (2011) and the Generalized Supremum Augmented Dickey-Fuller (GSADF) test developed by Phillips et al. (2015) are used to identify multiple bubble periods. The empirical findings imply that positive bubbles are a common feature of the closing rate of EUR/USD exchange in the COVID-19 outbreak. As a critical year, 2020 is identified to point out the importance of explosive bubble behavior, after which estimated statistics by two types of unit-root test procedures provide evidence of ongoing financial instability.</p> 2021-08-26T00:00:00+00:00 Copyright (c) 2020 Journal of Sustainable Economics and Management Studies https://dergiler.gelisim.edu.tr/index.php/ecoman/article/view/12 Liquidity Timing Ability of Fund Managers under Changing Market Dynamics 2021-03-22T12:22:47+00:00 Hale YALÇIN hale.yalcin@yeditepe.edu.tr Sema DUBE sdube@yeditepe.edu.tr <p>We examine the liquidity timing ability of Turkish variable fund managers during 2011-2018, and how this ability is affected by the environmental factors such as the technological advancement level, the presence of derivatives market, the growth in the overall economy, the level of market openness, and the performance of portfolios for bond, gold, real estate, foreign exchange, emerging markets. We use interaction variables within a panel data framework. We find strong evidence of the liquidity timing ability of mutual fund managers even after controlling for environmental factors. The nature of the interactions for most of the control factors with liquidity timing ability is strongly significant and differs based on the factor.</p> 2021-08-26T00:00:00+00:00 Copyright (c) 2020 Journal of Sustainable Economics and Management Studies https://dergiler.gelisim.edu.tr/index.php/ecoman/article/view/17 Reserve Options Mechanism and Exchange Rate Volatility: An Implementation for Turkey 2021-04-12T22:30:43+00:00 Lokman KANTAR lkantar@gelisim.edu.tr <p>Due to the flexible monetary policies implemented during the crisis, low-interest rates obtained funds has moved towards countries with emerging economies and that caused speculative attacks (the volatility in exchange rates, capital market etc. to make short-term trades.) on countries such as Turkey. Therefore, Turkey has developed a set of measures to ensure price stability along with financial stability. One of these measures is the Reserve Option Mechanism, which enables TL required reserves to be held in foreign currency. Foreign currencies entering the country through the Reserve Options Mechanism will not enter the economy directly, and some of this money will be kept by the CBRT as required reserves by banks. Thanks to this mechanism, it is aimed to reduce the volatility in exchange rates. In this study, the effect of Reserve Options Mechanism on exchange rate volatility has been examined.</p> 2021-08-26T00:00:00+00:00 Copyright (c) 2020 Journal of Sustainable Economics and Management Studies https://dergiler.gelisim.edu.tr/index.php/ecoman/article/view/27 Renewable Energy Use and Energy Productivity: A Panel Data Analysis 2021-07-14T14:10:52+00:00 Gonca YILMAZ goyilmaz@gelisim.edu.tr Esat DAŞDEMİR edasdemir@gelisim.edu.tr <p>This study emphasizes renewable energy source use's effects on productivity, competitiveness, and growth. The hypothesis of the study was tested with panel data analysis on European and Central Asian countries. Panel data analysis covered 15 Eurasian countries with data from 1990-2014. In our hypothesis, renewable energy use increases income by increasing efficiency in production. The model established reveals the difference between various energy types and renewable energy. Analysis outputs support the study hypothesis. According to the results, the increase in the share of renewable energy use in total energy use affects per capita income positively. On the other hand, an increase in the share of fossil fuels decreases per capita income. Our study suggests that countries aiming for better economic growth should increase their use of renewable energy.</p> 2021-08-26T00:00:00+00:00 Copyright (c) 2020 Journal of Sustainable Economics and Management Studies
