the joint determination of the non-linear monitoring and tax schedules and the conditions under which these can be … implemented. Monitoring of labor effort reduces the distortions created by income taxation and raises optimal marginal tax rates …, possibly above 100 percent. The optimal intensity of monitoring increases with the marginal tax rate and the labor …

It is common knowledge that mobile individuals are difficult to tax. Governments accommodate these difficulties by … granting special tax reductions to mobile individuals as it is expedient to get some tax revenue from these individuals rather … than to lose them as tax payers completely. Taxing according to expediency is, however, criticized by ordinary tax payers …

The present study provides estimates of the Effective Marginal Tax Rates (EMTRs) for a sample of 17 OECD countries and …-country/cross-sector approach allows us comparing the incentives provided by the tax systems and gauging the effects of tax changes taking … explicitly into account the possible substitution between factors as well as their tax incidence. Our results suggest that the …

This paper studies the design of tax systems that implement a planner's second-best allocation in a market economy. An … example shows that the widely used Mirrleesian (1976) tax system cannot implement all incentive-compatible allocations … one tax system. However, this tax system is often undesirable since it severely restricts the choice space of agents in …

Many countries apply lower fines to tax evading individuals when they voluntarily disclose the tax evasion they … to evade taxes, they nevertheless increase tax revenues net of administrative costs.

This paper estimates the intensive and extensive-margin tax-price elasticities of giving using UK administrative tax … return data, exploiting variation from a large tax reform. Using a variety of estimation methods and new instruments for the … tax-price of giving, we find an intensive-margin elasticity of about -0.25 and an extensive-margin elasticity of -0 …

-sufficiency of the ETI, namely tax deductions. Building on a theoretical framework which incorporates deductions in a standard … optimal-tax model, we show that the ETI is not sufficient for welfare analysis if (i) deductions generate externalities and if … (ii) deductions are responsive to tax-rate changes. While the first condition should arguably hold true for the majority …
