Executive Partisanship and Corporate Investment

Abstract I show that an alignment in partisan affiliation, between a firm’s management and the president, is associated with higher levels of investment. Using insider trading data, I find that managers become more optimistic about their companies’ prospects when their preferred party is in power. This optimism-driven increase in investment is amplified by herding and associated with both lower profitability and stock returns. Overall, managers’ political beliefs produce heterogeneous expectations about future cash flows and distort investment decisions.
