Short‑ and long‑run macroeconomic impacts of the 2010 Iranian energy subsidy reform

This paper examines the short- and long-run effects of the 2010 Iranian energy subsidy reform on macro indicators including GDP and inflation. The subsidy reform, which consists of a simultaneous energy subsidy cut and a cash transfer to households, is not fiscally motivated but instead aims to reduce energy consumption. Using timeseries to analyse the dynamics of the macro variables in response to the subsidy reform elements (energy price increase, and cash transfer), this study reveals that the subsidy reform has a negative effect on the economy in the short- and midterm, and the cash transfer to households does not fully compensate for this adverse effect. These results are robust and consistent across specifications. The main channel that transmits the effect of energy price to GDP is value-added of industry and service sectors. The long-run analysis rejects the existence of a long-run relationship between the energy subsidy reform and GDP. The findings indicate that the energy subsidy reform does not result in a reduction in energy consumption. These findings challenge the environmental aspect of the fossil fuel subsidy reforms as stand-alone policies without major reforms in the energy efficiency of economic sectors.

本文探究了2010年伊朗能源补贴改革对国内生产总值（GDP）、通货膨胀率等宏观经济指标的短期与长期影响。此次能源补贴改革同时实施能源补贴削减与家庭现金转移支付两项举措，其初衷并非出于财政考量，而是旨在降低能源消费。本研究采用时间序列分析法，探究宏观经济变量对补贴改革两项核心举措——能源价格上调与家庭现金转移支付——的动态响应，结果显示，该补贴改革在短期与中期内会对经济产生负面影响，且家庭现金转移支付无法完全抵消这一不利效应。上述研究结果具备稳健性，且在不同模型设定下均保持一致。能源价格变动影响GDP的核心传导渠道为工业与服务业增加值。长期分析结果表明，能源补贴改革与GDP之间并不存在长期关联。研究结果显示，此次能源补贴改革并未实现降低能源消费的政策目标。上述发现对"将化石燃料补贴改革作为无需配合经济部门能源效率重大改革的独立政策"这一做法的环境效益提出了质疑。
