[We show that familiarity affects the portfolio decisions of mutual fund managers. Controlling for fund location, funds overweight stocks from their managers' home states by 12% compared with their peers. In team-managed funds, home-state overweighting is 37% larger than the fund location effect. The home-state bias is stronger if the manager is inexperienced, is resource-constrained, or spent more time in his home state. Home-state stocks do not outperform other holdings, confirming that home-state investments are not informed. The overweighting also leads to excessively risky portfolios.]

We find that firms behave consistently with how their CEOs behave personally in the context of leverage choices. Analyzing data on CEOs' leverage in their most recent primary home purchases, we find a positive, economically relevant, robust relation between corporate and personal leverage in the cross-section and when examining CEO turnovers. The results are consistent with an endogenous matching of CEOs to firms based on preferences, as well as with CEOs imprinting their personal preferences on the firms they manage, particularly when governance is weaker. Besides enhancing our understanding of the determinants of corporate capital structures, the broader contribution of the paper is to show that CEOs' personal behavior can, in part, explain corporate financial behavior of the firms they manage.
