What do small firms do when given a semi-permanent corporate income tax cut? We examine firm responses to a substantial reduction in the tax rate for small- and micro-profit enterprises (SMPE) in China, using gradual increases in the qualifying threshold during 2010–2016 for identification. Based on confidential tax returns, we find that newly qualified SMPEs with immediate tax savings increased investment and productivity, while there was no change in wages or payout to shareholders. There is some weak evidence the tax cut induced entry of micro-sized firms in financially constrained sectors. Yet its size-based design led to bunching and incentivized firms to slow down growth when they approached the size threshold.

The return on government debt is lower than that of assets with similar payoffs. We study optimal debt management and taxation when the government cannot directly redistribute toward the agents in need of liquidity but otherwise has access to a complete set of linear tax instruments. Optimal government debt provision calls for gradually closing the wedge between the returns as much as possible, but tax policy may work as a countervailing force: as long as financial frictions bind, it can be optimal to tax capital even if this magnifies the discrepancy in returns.
