    Personal-Service-Agenturen (PSA) sind vermittlungsorientiert arbeitende Zeitarbeitsunternehmen. Sie wurden im Zuge der Hartz-Reformen in das Instrumentenspektrum des SGB III eingeführt. In diesem Beitrag werden erste Ergebnisse der Evaluation der PSA vorgestellt. Zunächst werden die rechtlichen Grundlagen des Instruments, die Umsetzung durch die Bundesagentur für Arbeit, die institutionellen Rahmenbedingungen sowie die Nutzung des Instruments erörtert. Anschließend werden wirkungsanalytische Ergebnisse präsentiert. Die Ergebnisse der ersten Analysen sind ernüchternd: Zwar zeichneten sich in der Startphase 2003 positive Integrationswirkungen ab, im Jahre 2004 hatten PSA-Beschäftigte nach bisherigen Erkenntnissen jedoch eine deutlich geringere Wahrscheinlichkeit, innerhalb des untersuchten Zeitraums wieder in eine reguläre Beschäftigung eingegliedert zu werden. Abstract Personnel Service Agencies (PSA) are placement-oriented temporary work agencies, an innovative program for the reintegration of the unemployed introduced by the so-called “Hartz reforms.” This paper reports interim findings of an implementation and microeconomic impact analysis. After an initially positive reintegration effect during the start-up phase of the program in 2003, PSA participants had a markedly lower probability of entering regular employment in 2004 than did a control group

    If You Pay Peanuts …: A Laboratory Experiment on Reward Schemes in Employment Service Contracting

    The design of tenders and contracts is a crucial factor in the success or failure of the contracting-out of reintegration services. In a laboratory experiment with professionals from private reintegration service providers, we tested two tender designs. In the first design, the government announces a predetermined amount that will be paid for each employment outcome. Participants then bid an amount of money that they are prepared to pay to operate the contract. This auction resembles contracting in the Australian Job Network and the British Employment Zones. The second design is the lowest-reward auction. In this auction, the participants bid a reward. The lowest bid wins the contract, and the reward is then paid for each unit of effort. The lowest-reward auction is similar to the current tendering practice in the Netherlands.We find that an auction with a fixed reward per placement is more efficient, yields more effort from the winner, and results in higher welfare than an auction in which bidders compete on the basis of the reward per placement. We derive this conclusion from both our theoretical analysis and data from our laboratory experiment with professional bidders
