Price volatility spillovers in ISE indexes were analysed based on monthly data from January 1991 to January 2004 for exchange rate, interest rate, inflation, industrial production and M1 money supply. The Exponential Generalized Autoregressive Conditional Heteroscedasticity model was used to test univariate volatility spillovers for macroeconomic variables. It was found that there exists unidirectional strong volatility spillover from inflation, interest rate to all stock price indexes. There are spillovers from M1 money supply to financial index, and from exchange rate to both IMKB 100 and industrial indexes. There is no volatility spillover from industrial production to any index.

Investigation of academic dishonesty has increased markedly in the past two decades; however, the body of research offers inconclusive evidence for many variables. This study examines faculty and student perceptions of in-class and outof-class cheating behaviours and provides contextual evidence for the prevalence of assessment practices used. Faculty and students differed only slightly in their attitudes toward collegiate cheating and their views on possible reasons for it. We found that the prevalence of teaching and assessment types used in student grading is significantly correlated with perceptions of out-of-class cheating, but not with out-of-class cheating behaviours. Students with less experience in out-of-class assessment display a less ethical attitude toward out-of-class cheating.

In this study, technical, allocative and economic efficiency scores of the banks whose stocks traded in Istanbul Stock Exchange are measured using data envelopment analysis (DEA) for the time period 1998 to 2004. Economic efficiency scores of banks obtained from DEA model was related to their stock prices to determine whether there is an explanatory power of efficiency scores on stock price returns. The average banks’ efficiency decreased from 0.781 in 1999 to 0.504 in 2001 and started to increase after this year except the year of 2003 indicating that financial crises affected the efficiency scores of the banks. During the time period 1998 to 2004, six banks appeared to be technically efficient at least once.

The tourism sector makes significant contributions to national and regional development. On the other hand, emerging political instabilities and any crisis have a significant impact on the development of the sector. In this study, it is aimed to determine the financial performance of companies within the scope of Istanbul Stock Exchange (ISE) Tourism index between 2009-2020. For this purpose, the Malmquist Total Factor Productivity index was created by using the financial ratios calculated from the financial statements of the companies. As a result of the study, it was determined that there was a significant decrease in the performances and productivity of tourism companies between 2016-2020. It has been revealed that the effects of the political crises that took place in Turkey were involved in the decrease in productivity in this period.
