The study looked at how a competitive firm makes production decisions when prices are uncertain and the firm is regret-averse. They found that firms may produce more when regret-averse compared to just being risk-averse. The optimal production level can change as the firm's regret-aversion increases. Overall, regret-averse firms tend to hedge their bets to account for the possibility of regretting their decisions later. This helps explain why price uncertainty doesn't have as extreme of an impact as expected with pure risk-averse preferences.
