By increasing current cash-flows tax cuts alleviate financing frictions, hereby stimulating current investment; multipliers are close to 1 for constrained firms, especially new entrants, & negative for larger & unconstrained firms

Financial Frictions and Stimulative Effects of Temporary Corporate Tax Cuts. William Gbohoui, Rui Castro. IMF Working Paper No. 19/97, https://www.imf.org/en/Publications/WP/Issues/2019/05/07/Financial-Frictions-and-Stimulative-Effects-of-Temporary-Corporate-Tax-Cuts-46641

Summary: This paper uses an industry equilibrium model where some firms are financially constrained to quantify the effects of a transitory corporate tax cut funded by a future tax increase on the U.S. economy. It finds that by increasing current cash-flows tax cuts alleviate financing frictions, hereby stimulating current investment. Per dollar of tax stimulus, aggregate investment increases by 26 cents on impact, and aggregate output by 3.5 cents. The average effect masks heterogeneity: multipliers are close to 1 for constrained firms, especially new entrants, and negative for larger and unconstrained firms. The output effects extend well past the period the policy is reversed, leading to a cumulative multiplier of 7.2 cents. Multipliers are significantly larger when controlling for the investment crowding-out effect among unconstrained firms.
