UK proposed corporate tax reform results #52

One of the proposals from a few of the leadership candidates earlier this month was to set the UK corporate income tax rate at 15% (it's currently 19% and set to rise to 25% in 2023).

I just tried running this through OG-UK and got the following result (percent formatted).

Variable 2022 2023 2024 2025 2026 2027 2028 2029 2030 2031 2022-2031 SS
GDP ($Y_t$) +0.07% +0.13% +0.15% +0.16% +0.20% +0.12% +0.11% +0.09% +0.08% +0.07% +0.12% +0.27%
Consumption ($C_t$) -0.04% -0.92% -0.20% -0.02% +0.06% +0.13% +0.16% +0.17% +0.18% +0.19% -0.03% +0.47%
Capital Stock ($K_t$) +0.09% +0.25% +0.46% +0.49% +0.53% +0.55% +0.54% +0.53% +0.51% +0.49% +0.44% +1.20%
Labor ($L_t$) +0.05% +0.07% -0.01% -0.01% +0.02% -0.12% -0.13% -0.14% -0.15% -0.16% -0.06% -0.23%
Real interest rate ($r_t$) +0.98% +2.37% +1.98% +1.93% +1.92% +1.72% +1.70% +1.70% +1.71% +1.72% +1.77% +0.76%
Wage rate +0.01% +0.06% +0.16% +0.18% +0.18% +0.23% +0.24% +0.24% +0.23% +0.23% +0.18% +0.50%

For a ten-point rate cut, these results seem small. I'm definitely reading them right as already percentages right? It could also be the fact that we're still using the linear tax fit.
