Increasing globally terrorist acts have caused several economic, politic and social problems. One of them is that distorting effects of terrorist attacks are targeting tourism destinations on tourism demand. Increasing terrorist acts in Turkey where is the important tourism center have required that investigation for potential effects of terror and insecurity environment on tourism sector. For this purpose, the sensitivity of tourism demand from OECD countries to the Turkey in 1992-2011 against terrorist incidents analyzed by Fixed Effects Panel Data Methodology and the effects of terrorist attacks on tourism preferences investigated empirically. Contrary to popular opinion, the main findings of the model show that distorting effects of terrorist acts on tourism demand aren't remarkable in Turkey. Study contribute to the relatively inadequate empirical literature by emphasising the security perspective as the determinants of tourism demand.
