Abstract: In this paper we experimentally study what happens to the long-term relationship between a firm and a worker when the firm's profitability is affected by exogenous revenue shocks. While we find that shocks had no significant effect on wages and a little effect on relationships, we observe their significant effect on effort levels: Given the same wage, the workers exert lower effort in Shocks comparing to No Shocks. Hence, the presence of shocks in our experiment decreases market efficiency.
Keywords: Gift exchange, experiment, exogenous shocks
