This paper re-examines the individual income tax evasion decision in the simple framework introduced by Allingham and Sandmo (1972), where the individual taxpayer decides how much of his income is invested in a safe asset (reported income) and in a risky asset (concealed income). These early...

We investigate experimentally if endogenous partnership formation can improve efficiency in social dilemma situations. Subjects play multiple two-player public goods games, where they can break up with their current partner after every fourth game. Subjects without a partner provide rankings of...

Firms are usually better informed than tax authorities about market conditions and the potential profits of competitors. They may try to exploit this situation by under-reporting their own taxable profits. The tax authority could offset firms' informational advantage by adopting "smarter" audit...

We test if confusion and learning could potentially explain all the decay of contributions in the repeated public goods games by implementing a limited information environment to mimic the state of confusion. A comparison shows that the rate of decline is more than twice as high in a standard...

In this paper we investigate experimentally if people search optimally and how price promotions influence search behavior. We implement a sequential search task with exogenous price dispersion in a baseline treatment and introduce discounts in two experimental treatments. We find that search...

We implement a simple two-shop search model in the laboratory with the aim to investigate if consumers behave differently in equivalent situations, where prices are displayed either as net prices or as gross prices with discounts. We compare treatments, where we either depict the known price of...

Consumers often complain that retail prices respond faster to increases in wholesale prices than to decreases. Despite many empirical studies confirming this 'Rockets-and-Feathers' phenomenon for different industries, the mechanism driving it is not well understood. In this paper, we show that,...

We develop a moral hazard model with auditing where both the principal and the agent can influence the probability that the true state of nature is verified. This setting is widely applicable for situations where fraudulent reporting with costly state verification takes place. However, we use...

This paper re-examines the individual tax-evasion decision. The standard portfolio approach is used to explain why higher tax rates and a higher gross income induce more tax evasion. These empirical facts could not be explained simultaneously with thin the standard framework before. We show...

We present an experimental study on the wasted resources associated with tax evasion. This waste arises from taxpayers and tax authorities, investing costly effort in concealment, respectively detection, of tax evasion. We show that (socially inefficient) efforts depend positively on the...
