Tax wedges, financial frictions and misallocation
研究了公司税对劳动和资本的影响，发现税收增加导致生产从C型公司转向穿透型企业，降低劳动生产率和工资，并加剧资本和人才的错配。
We revisit the classical result that in a closed economy the incidence of corporate taxes on labor is approximately zero. We consider a rich general equilibrium framework, where agents differ in the level of their wealth as well as in their managerial and working ability. Potential entrepreneurs go through all the key decisions affected by corporate tax changes: the choice of (i) occupation, (ii) organizational form, (iii) investment, and (iv) financing structure. We allow both for the presence of financial frictions and the traditional tax advantage of debt over corporate equity, which jointly generate misallocation of capital and talent. In this environment we characterize the effects of increasing corporate taxes both analytically and for a calibrated version of the model. We show that this tax increase reallocates production from C corporations to pass-through businesses. Since, due to distorted prices, the latter have higher capital-labor ratios, this reallocation generates a reduction in labor productivity and wages. Furthermore, the corporate tax increase induces some C corporations to reorganize as pass-throughs, which implies more restricted access to external funds and thus a socially inefficient downsizing of production in these firms. Finally, the tax increase causes further misallocation of talent by inducing agents with low wealth relative to their managerial talent to switch from entrepreneurship to being workers, while the reverse happens for agents with higher wealth and lower managerial skills. Overall, we find that both labor and capital bear a large share of the corporate tax incidence, while entrepreneurs are net beneficiaries of the tax change.
