We study nonlinear income taxation in a Roy model in which agents' productivity is sectorspecific. We show that when income taxes can be sector-specific, the Diamond-Mirrlees theorem (according to which the second-best displays production efficiency) fails: social welfare (be it Rawlsian or...

This paper is concerned with a policy oriented macroeconomic experiment involving an international economy with a relatively small home country and a large foreign country. It compares the economic performance of two alternative tax systems as a means to finance unemployment benefits: a...

This paper analyzes the effects of an income tax credit for hard-to-tax consumer services on evasion of the value-added-tax (VAT). Based on the individual tax files of the universe of VAT payers in Germany, our analysis shows that harnessing incentives for consumers through tax credits fosters...

State borders create a discontinuous tax treatment of retail sales. In a Nash game, local tax rates will be higher on the low-state-tax side of a border. Local taxes will decrease from the nearest high-tax border and increase from the low-tax border. Using driving time from state borders and all...

The employment of capital is rival in nature. Small countries do not benefit from taxing its employment. By contrast, the use of digital services is non-rival and small countries do benefit from taxing expenditures on such services. In fact, some countries have already decided to tax digital...

We develop a tax competition model that allows for the setting of both an origin-based and a destination-based commodity tax rate in the presence of avoidance and evasion. In the presence of evasion, jurisdictions will give cross-border shoppers tax preferential treatment, thus not fully...

I leverage a Pakistani tax reform that cuts the tax rate on the supply chains of five major industries of the country from 15% to 0% to cast light on the extent of, and mechanisms driving, VAT noncompliance in a representative emerging economy. I find that firms overclaim refunds by 22% and...

Pension benefit rules depend on individual history far more than taxes do, and age plays a much larger role in pension determination than in tax determination. Apart from some simulation studies, theoretical studies of optimal tax design typically contain neither a mandatory pension system nor...

We derive a general optimal income tax formula when individuals respond along both the intensive and extensive margins and when income effects can prevail. Individuals are heterogeneous across two dimensions: their skill and their disutility of participation. Preferences over consumption and...

In our dynamic optimizing sticky price model, agents are heterogeneous with regard to their age and their productivity. We find that the business cycle dynamics in the OLG model in response to both a technology shock and a monetary shock are similar, but not completely identical to those found...
