The data set covering the Marmara region was expanded to cover all Turkey, and the hypotheses in the research model created by extending the period were retested and the study was repeated. The sector was analyzed on a country basis by comparing the findings. In this research, a survey was conducted with 475 people working in managerial positions in firms operating in the Turkish logistics sector. Empirical evidence regarding the mediating role of strategic posture was obtained from this study. As a result, it was determined how important it is for Turkish logistics companies to have a strategic posture, and it is a very important complement in terms of improving performance. In addition, the necessity for companies examined within the scope of the study to make strategic choices in line with the impact of environmental conditions was revealed.

For this purpose, an online questionnaire is adapted from the Spielberger State-Trait Anxiety Inventory (STAI), and sent to the 1111 participants from both sectors. It is hypothesized that economic anxiety would have a greater effect on private sector employees than public sector employees while the health anxiety has more dominant effects on public sector employees. To test the significance level of the mean differences between these groups, an independent sample t test was used and for testing the significance level of the mean differences among three or more groups one-way analysis of variance (ANOVA) was used. The t test results revealed that private sector employees had higher levels of economic anxiety on average than public sector employees. While there is no significant difference between the sectors in terms of health anxiety, routine change anxiety is higher on average over all other anxiety levels for both sectors. According to the results of one-way ANOVA test, employees living in minimum subsistence conditions, i.e., low-income group, had much more intense levels of economic anxiety than high-income group, and it was concluded that high-income group was under psychological pressure due to the routine changes they experienced. Finally, the results showed that private sector employees were more feared about getting short-time working allowances compared to public sector employees.

In this phase, systemic risk factors are increased, negative events and expectations became more likely to spread and effect all markets. Particularly in stock markets, it is seen that markets of many countries integrated with “global” market rapidly, but level of this integration has not reached to remarkably high levels and does not result with strong co-movements. Even faced crises cause similar reactions in stock markets in short-term, after-shock movements may show distinct characteristics. In this framework, possible effects of World Health Organization’s pandemic announcement for the disease COVID-19, which is made on 11 March 2020, on the changes in co-movements of stock markets are investigated by using Principal Component Analysis and a change point detection analysis. Daily index movements until the date 31.12.2020 of 20 stock markets, including Turkey are used in analyses. Additionally, impact of pandemic related local numbers and restriction levels on Turkish stock market is examined.

In this context, institutions where behaviors become a set of formal-informal rules that determine the boundaries of choice for the stakeholders of the society from thought to action and form the framework of individual action by gaining stability, are of great importance in terms of developing an economic thinking system compatible with the real world. With its dynamic perspective on economic events and phenomena, the institutional economic tradition has revealed important discoveries by evaluating the effects of institutions on the economic order from different perspectives and closed a major gap in this area. With this study, the historical adventure of institutional economics, which started with the pioneering studies that Thorstein B. Veblen put forward based on the Darwinian evolution approach, has been discussed from the perspective of old and new institutional economics. By presenting the contributions of the prominent representatives of the tradition to economic thought through labor included in the analysis, it is aimed to open a door from the perspective of institutionalized behavior to studies on the economic impact of human behavior. In addition, the evaluations for the sustainability of the institutional tradition were discussed, and the advantages and disadvantages of the tradition in question were emphasized within the framework of today's prevailing economic approach.

Our focus is on the distinction between firms’ product quality improvement and variety extension objectives. We use data from Turkish Statistical Institute (TURKSTAT) Innovation Survey between the years 2014 and 2016. According to the descriptive results, number of firms report that product quality as very important is greater than the firms report that product variety. Logit estimations results show that majority of the product variety objective and technology level indicators are significant and positively related with probability of product innovation. There is also a positive relationship between probability of product innovation and patent applications for small and medium sized firms. Moreover, probability of innovation is positively related with variety objective whereas quality objective indicators are insignificant.
