Final answer:
Reducing income tax rates often leads to lower earners increasing their work hours due to higher take-home pay, while higher earners may work less as they have sufficient income from the tax cut to afford more leisure time.
Step-by-step explanation:
The most likely outcome of the Finance Minister Pom Pom's policy of reducing income tax rates in the country of Burnination is that lower earning workers will work more, while higher earners may work less. This is due to a phenomenon known as the backward-bending supply curve for labor. Part-time workers may respond to higher take-home wages by working additional hours to increase their income. However, individuals with higher incomes might opt to enjoy more leisure time instead, as the tax cut provides them with sufficient income without the need for extra work hours. The effect of the tax reduction on the labor supply is thus not uniform and depends on individual circumstances and preferences.
