Disabled insurance (DI) beneficiaries lose benefits if labor incomes exceed certain thresholds (so called cash-cliffs ). The high implicit taxation of employment income is considered one of the prime reasons for the low outflow from the disability insurance. This paper presents the results of...

Disability insurance (DI) beneficiaries lose part of their benefits if their earnings exceed certain thresholds ("cash-cliffs"). This implicit taxation is considered the prime reason for low DI outflow. We analyse a conditional cash program that incentivises work related reductions of disability...

Disability insurance (DI) beneficiaries lose part or all of their benefits if earnings exceed certain thresholds ("cash-cliffs"). This implicit taxation is considered the prime reason for the low number of beneficiaries who expand work and reduce benefit receipt. We analyse a conditional cash...

This paper investigates the effects of different prize structures on the effort choices of participants in two-stage elimination contests. A format with a single prize is shown to maximize totaleffort over both stages, but induces low effort in stage 1 and high effort in stage 2. By contrast, a...

We report results from experimental first-price, sealed-bid, all-pay auctions for a good with a common and known value. We observe bidding strategies in groups of two and three bidders and under two extreme information conditions. As predicted by the Nash equilibrium, subjects use mixed...

This papers proposes a simple method for testing whether non-compliance in experiments is ignorable, i.e., not jointly related to the treatment and the outcome. The approach consists of (i) regressing the outcome variable on a constant, the treatment, the assignment indicator, and the...
