Taxation Theory Quiz

Choose the right answer:

• The assumptions on the distribution of abilities determine the optimal top marginal rate. In some cases, it can be as higher as 80%

• Optimal taxation theory is concerned about the distribution of taxes across income groups

• Wage cannot be considered as a proxy of abilities

• None of the above

Choose the right answer:

• Optimal redistribution is reduced with wage inequality

• Optimal redistribution increases with wage inequality

• Optimal redistribution increases with tax incidence

• None of the above

Recall the theory behind the Laffer curve and choose the WRONG answer:

• The Laffer Curve is a theoretical framework that can be used to justify that tax increases can increase tax revenue

• The Laffer Curve is a theoretical framework from which it can be unequivocally concluded that a tax reduction increases tax revenue

• The Laffer Curve is a theoretical framework that explains that there are two opposing effects of a tax increase in terms of tax revenue. One, the increase in tax revenues and, two, the potential effect on individuals labor supply

• The Laffer Curve is a theoretical framework within the theory of optimal taxation that has mainly been used to justify tax cuts

Concerning equity in taxation theory, choose the right answer:

• Optimal taxation theory determines what is the optimal degree of inequality that an economy can bear

• The ultimate determinants of equity fall outside Pareto optimality

• Taxing individual characteristics such as height can never be optimal

• None of the above

Recall the progressivity analysis in taxation theory and choose the right answer:

• Progressivity has declined over the years but personal income taxes in OECD countries still have progressive tax schedules

• Local and global progressivity can be measured with the same tools

• Global progressivity can be analysed through the relation between marginal tax rates and average tax rates

• None of the above

According to the Laffer Curve...

• Tax reductions always result on tax collection increases

• Economic growth accelerates tax collection

• Government budget deficit decreases

• Might be used for advising tax increases or decreases

Ramsey rule optimal conditions (income taxation)...

• Concerns tax elasticities

• Stablishes the equalization of the ratio of marginal dead weight loss in respect to marginal revenue for all incomes

• Establishes that the ratio of marginal deadweight loss to marginal revenue should be equalized across all income levels (broad-based rule) and that goods with more inelastic demand should be taxed at higher rates (inverse elasticity rule)

• Establishes that the ratio of marginal deadweight loss to marginal revenue should be equalized across all income levels (inverse elasticity rule) and that goods with more inelastic demand should be taxed at higher rates (broad-based rule)

What the main justifications for progressive taxation: i ii and i i, ii and iii None

• i

• ii and i

• i, ii and iii

• None

What is the primary driver of deadweight loss in taxation?

• Elasticity of supply and demand

• Tax collection costs

• Government expenditures

• Economic growth

How does vertical equity influence tax policy?

• It ensures all individuals are taxed at the same rate

• It requires different treatment based on economic differences

• It eliminates all forms of income inequality

• It simplifies tax administration
