Information aversion—a preference-based fear of news flows—has rich implications for decisions involving information and risk-taking. It can explain key empirical patterns on how households pay attention to savings, namely, that investors observe their portfolios infrequently, particularly when stock prices are low or volatile. Receiving state-dependent alerts following sharp market downturns, such as during the financial crisis of 2008, improves welfare. Information-averse investors display an ostrich behavior: overhearing negative news prompts more inattention. Their fear of frequent news encourages them to hold undiversified portfolios.
