我们利用意大利房主的原始调查数据评估意大利住宅能源升级的激励措施。在本文中，关注仅限于供热系统的更换，以及货币和非货币激励对用更有效的供热设备更换供热设备的倾向的影响。为了避免逆向选择和搭便车的问题，我们向那些不打算近期升级能源效率的人提出了明确的偏好问题。我们认为这些人不会受到这些行为的影响。我们用他们的回答来拟合一条能源效率改造曲线，该曲线预测在任何给定的激励水平下，将进行这些改进的人口比例。这条曲线用于估计节省的二氧化碳排放量及其成本效益。当能源账单上的节省更大，在更长的时间内体验到，以及当向他们提供回扣时，受访者更有可能同意更换。提醒人们注意二氧化碳（我们的非金钱激励）几乎没有效果。即使在乐观的假设下，与意大利税收抵免计划相当规模的激励措施的成本效益通常也是不利的。
We evaluate incentives for residential energy upgrades in Italy using data from an original survey of Italian homeowners. In this paper, attention is restricted to heating system replacements, and to the effect of monetary and non-monetary incentives on the propensity to replace the heating equipment with a more efficient one. To get around adverse selection and free riding issues, we ask stated preference questions to those who weren’t planning energy efficiency upgrades any time soon. We argue that these persons are not affected by these behaviors. We use their responses to fit an energy-efficiency renovations curve that predicts the share of the population that will undertake these improvements for any given incentive level. This curve is used to estimate the CO2 emissions saved and their cost-effectiveness. Respondents are more likely to agree to a replacement when the savings on the energy bills are larger and experienced over a longer horizon, and when rebates are offered to them. Reminding about CO2 (our non-monetary incentive) had little effect. Even under optimistic assumptions, the cost-effectiveness of incentives of size comparable to that in the Italian tax credit program is generally not favorable.
