  In the current study, the impact of economic uncertainty on stock liquidity has been investigated with an emphasis on CEO tenure. This research is practical in purpose, and from a correlation methodological perspective, it is causal (post-event). The research population consists of companies admitted to the Tehran Stock Exchange. A systematic elimination sampling method has been used to select 124 companies from 2012 to 2019. In this research, macroeconomic variables, including changes in the inflation rate, interest rate, exchange rate and gross domestic product (GDP), have been used to assess economic uncertainty. Furthermore, both autoregressive conditional heteroscedasticity (ARCH) and generalized autoregressive conditional heteroscedasticity (GARCH) models have been employed to investigate uncertainty. Finally, by using the panel data model and multivariate regression, research hypotheses have been investigated. According to the results of the classical hypothesis test based on variance heterogeneity, the generalized least squares (GLS) method has been utilized. According to research findings, economic uncertainty has a substantial impact on stock liquidity. The interactive effects of CEO tenure along with changes in inflation and interest rates on stock liquidity are inverse and significant. For economic growth and exchange rate changes, however, they are positive and significant. . Manuscript profile
