More progressive income taxes raise employment in models of imperfectly competitive labour markets. However, this prediction is not robust to modifications of the analytical structure. For example, in an efficiency wage setting, more progressive taxes reduce profits. This induces firms to exit...

A tax buyout is a contract between tax authorities and a tax payer which reduces the marginal income tax rate in exchange for a lump-sum payment. While previous contributions have focussed on labour supply, we consider the interaction with tax evasion and show that a buyout can increase expected...

Status considerations with respect to consumption give rise to negative externalities because individuals do not take into account that their decisions affect the relative consumption position of others. Further, status concerns create incentives for excessive labour supply in competitive...

Applying a framework of perfect competition under uncertainty, we contribute to the discussion of whether or not ad valorem taxes and specific taxes are equivalent. While this equivalence holds without price uncertainty, we show that ad valorem taxes and specific taxes are “almost never”...

In 2004, a section was added to the German Protection against Dismissal Act, establishing a new procedure to dismiss an employee, given a predetermined severance payment. Most legal scholars presume the change to be without impact, while a minority of experts claims it to be either beneficial or...

In Germany, there is no trade union membership wage premium, while the membership fee amounts to 1% of the gross wage. Therefore, prima facie, there are strong incentives to free-ride on the benefits of trade unionism. We establish empirical evidence for a private gain from trade union...

In a partial equilibrium setting without price uncertainty, the balanced-budget substitution of an ad valorem tax on output for a specific (unit) tax can enhance welfare in imperfectly competitive markets and is without impact in a competitive world. This paper demonstrates that a substitution...

In 1996, statutory sick pay was reduced for private sector workers in Germany. Using the empirical observation that trade union members are dismissed less often than non-members, we construct a model to predict how absence behaviour will respond to the sick pay reform. We show that union members...
