我们分析了对耐用产品技术的有效补贴。我们从理论上证明了政策制定者在设计一种随时间增加的补贴和设计一种随时间减少的补贴以利用未来技术进步之间面临着一种紧张关系。通过对加州家庭对住宅太阳能的偏好进行动态估计，我们发现有效补贴随着时间的推移而增加。当家庭预期未来的技术进步和未来的补贴时，监管机构的支出会增加五倍。
We analyze the efficient subsidy for durable good technologies. We theoretically demonstrate that a policy maker faces a tension between intertemporally price discriminating by designing a subsidy that increases over time and taking advantage of future technological progress by designing a subsidy that decreases over time. Using dynamic estimates of household preferences for residential solar in California, we show that the efficient subsidy increases over time. The regulator’s spending quintuples when households anticipate future technological progress and future subsidies.
