This dissertation goal is to deepen our understand about firms\u27 resource allocation decisions. In the first chapter, using an NPV-based revealed-preference strategy, I find that idiosyncratic risk affects the discount rate that firms use in their capital budgeting decisions. I exploit quasi-exogenous within-region variation in project-specific idiosyncratic risk and find that, on average, firms inflate their discount rate by 5 percentage points (pp) in response to an 18pp increase in idiosyncratic risk. Moreover, these discount rate adjustments are negatively associated with measures of firm profitability. I then explore how proxies for costly external financing and agency frictions relate to discount rate adjustments. Consistent with th...
