"In this paper, we propose a model in which the effects of taxation on growth are highly non-linear. Taxes have a small impact on long-run growth when taxes rates and other disincentives to investment are low or moderate. But, as tax rates rise, the marginal impact of taxation on growth also rises. This non-linearity is generated by heterogeneity in entrepreneurial ability. In a low-tax economy, the ability of the marginal entrepreneur is relatively low. So, increasing the tax rate leads to the exit of low-ability entrepreneurs and to a small decline in the growth rate. In a high-tax economy the ability of the marginal entrepreneur is relatively high. So, increasing the tax rate leads to the exit of high-ability entrepreneurs and in a large decline in the growth rate."Agora, é só decidir onde estamos colocados, como país.
