Abstract
This discussion paper resulted in an article in the 'Economic Journal (2007). Volume 117, issue 522, pages 1025-1050. One of the main findings of a large body of gift exchange experiments is that in an incomplete contracts environment workers on average do not shirk and usually provide more than the minimum enforceable effort level. In general, 40 to 60 percent of the workers reward higher wages with higher effort. These results are observed for simple one-employer - one-worker relationships. In this paper we investigate whether they generalize to the more realistic situation in which the employer employs several workers. We compare a bilateral gift exchange game with a treatment in which each employer has four workers. We find that effort levels in the latter treatment are only marginally lower. Gift exchange thus appears to be robust to increases in the size of the workforce and intention-based reciprocity rather than social preferences seems to be the main driving force behind gift exchange.
