报告摘要：
This paper investigates the allocative efficiency of green finance instruments through a general equilibrium model with heterogeneous firms and financial frictions. We emphasize the impact of the timing of financial instruments—’ex-post’, such as carbon taxes, versus ’ex-ante’, like green credit schemes—on the distribution of dirty capital and its environmental implications. Our study reveals that ex-post instruments inadvertently direct dirty capital towards financially constrained firms with higher emission intensity, potentially exacerbating economy-wide emission. Conversely, ex-ante instruments yield beneficial redistributions. The study emphasizes the significance of incorporating the distributive effects of green finance tools into their design and advocates for a general equilibrium viewpoint to evaluate their effectiveness comprehensively, highlighting the pivotal role of instrument timing.
