We conduct a field experiment with sellers of home-improvement services on two German online markets. We take the role of consumers and vary whether we request an invoice for the delivery of the service. In a market which allows anyone to sell anonymously, a willingness to evade is prevalent. In...

This paper proposes that the national focus of energy 'rebound' studies should be extended to an international context in the presence of supra-national agreements such as EU 20-20-20. The potential for energy efficiency improvements in one nation to impact energy use in others means that...

This paper explores the connection between the proliferation of cashless, or e-money, payments and value-added tax (VAT) compliance. We present both visual and descriptive evidence that illustrates a negative correlation between e-money use and VAT evasion, proxied by the VAT compliance gap for...

Taxpayers often view tax rules and filing processes as complicated. In this paper I study whether the perceived tax uncertainty among peers leads to a reduction of voluntary tax compliance. I find strong supportive evidence for this hypothesis using a survey experiment for a large representative...

Political feasibility of emission trading systems may crucially depend on the free initial allocation of emission allowances to energy-intensive industries in order to ameliorate adverse production and employment effects. We investigate the potential trade-off between such compensation and...

In 2005, an EU-wide emissions trading scheme covering major CO2 producing sites shall come into power. The key objective of the trading scheme is to promote cost-efficiency of carbon reduction within the EU. We identify policy-relevant tradeoffs between overall efficiency, compensation and...

This paper analyses the effects of a social assistance reform in Germany. In contrast to studies which are based on microsimulation methods we use a computable general equilibrium model which incorporates a discrete choice model of labour supply to simulate a variety of reform scenarios. The...

Starting in 2005, the EU will implement a CO2 emissions trading scheme. In this paper we show that the outspoken goals of economic efficiency and free allocation of allowances are incompatible with harmonized allocation rules. In general, the assignment of allowances is endogenous and differs...

We present a model that integrates the discrete working time choice of heterogenous households into a general equilibrium setting where wages are determined by sectoral bargaining between firms and trade unions. The model is calibrated to German micro and macro data. We then use it to analyse...
