Abstract: The effectiveness of tax policies targeting firms has been evaluated conventionally by the effects on firms directly affected by the tax policies. However, the indirect effects through the supply chains of the affected firms can be of first-order importance. This paper estimates the indirect effects of tax incentives for investment on firm performance through production networks, exploiting a quasi-experimental event of an investment stimulus policy targeting small and medium enterprises and unique proprietary data of supply chains in Japan. After confirming the direct effects, I find evidence suggesting that the indirect effects on direct suppliers are even larger than the direct effects, while no discernible effects are found on downstream firms. The absence of downstream effects appears to stem from treated firms crowding out the market share of untreated large firms, leading to an insufficient change in market prices. In total, while the tax policy successfully stimulates targeted small firms, its spillover effects are primarily confined to the upstream customers which tend to be large.
