The upper echelons theory postulates that the cognitive frameworks of top executives shape organizational decisions and behaviors. Based on this theory, this study contributes to the literature by analyzing the effects of the chief executive officer's (CEO) political ideology and political climate on variations in the market value of tourism firms resulting from their innovation activities. An empirical application was conducted on major U.S. hotel companies that have traded on the stock market for the last 25 years (1998–2022) and made innovation-related announcements. This application shows that, although the implementation of innovative activities positively affects a firm's market value, both the CEO's political ideology and the political climate influence the degree of change in the said market value. This study has fundamental theoretical implications for upper echelons theory by improving the understanding of how cognitive diversity derived from political ideology influences decision-making and its outcomes.
