英文文献摘要：
Water is a classic common pool resource, especially during drought. This paper studies the impact of changing storage levels on urban water usage in the context of a prolonged drought and an extensive public information campaign which emphasized communal responsibility for maintaining ‘dam levels’. We identify a substantial voluntary conservation response to changing storage levels. The paper thus contributes a rare piece of real-world, behavioral evidence that voluntary conservation varies with the need for such action. Our findings also imply that estimates of price elasticity may be biased and welfare costs of mandatory restrictions may be overstated in many studies.

水是一种典型的公共资源，特别是在干旱时期。本文研究了在长期干旱的背景下改变蓄水水平对城市用水的影响，并开展了广泛的宣传运动，强调了维护“大坝水位”的公共责任。我们确定了一个实质性的自愿保护反应，以改变储存水平。因此，这篇论文提供了一个罕见的现实世界的行为证据，表明自愿保护行为随行动的需要而变化。我们的发现还暗示，在许多研究中，对价格弹性的估计可能是有偏差的，而强制性限制的福利成本可能被夸大了。
