Before revision:   Solving analytically, we show that a negative regime shift induces an aggressive extraction behaviour due to shorter detectionperiods, creating a sense of urgency, and higher markup in prices . Precautionary behaviour can result due to decreasing resource rent.
After revision:  Solving analytically, we show that a negative regime shift induces an aggressive extraction behaviour due to a combination of faster detection, a sense of urgency, and higher markup in prices . Precautionary behaviour can result due to decreasing resource rent.
