Kahneman and Tversky introduced the prospect theory in their work published in 1979. Prospect theory has brought a new perspective to rational decision making. A rational individual is expected to attribute equal value to gain with the same amount of loss. However, the findings of experimental studies do not confirm this expectation and show the opposite. Loss aversion, which is one of the subjects discussed within the scope of prospect theory, is that an individual who compares the same amount of loss with the gain attributes more value to this loss than to the gain. Loss aversion is an important psychological concept that is receiving increasing attention in economic analysis. Experimental studies revealing that the psychology of taxpayers has an important place in their attitudes and behaviors towards taxes has given a new direction to the field of behavioral public finance. The aim of this study is to determine the factors affecting loss aversion from a behavioral finance perspective. Data were collected from 817 participants with the questionnaire technique. Logit regression model was used in the analysis of the data obtained by convenience sampling method. The loss aversion ratio, which was estimated at 2.25 by Tversky and Kahneman, was estimated at 4.50. Based on our findings, it can be argued that as the risk level of individuals increases, the rate of loss aversion decreases and as the population of the region they live in increases, the rate of loss aversion increases.
