讲座介绍:

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 mechanisms—’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 measures inadvertently direct dirty capital towards financially constrained firms with higher utilization, potentially exacerbating economy-wide emission intensity. Such theoretical prediction explains empirical bservations of Hartzmark and Shue (2023), indicating such strategies may be counterproductive. Conversely, ex-ante approaches 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.
