Budget-Based Contracts, Budget Levels, and Group Performance
In this paper, we experimentally investigate the effects of budget-based contracts and budget levels (performance targets) on group performance. We compare a group piece-rate contract with two different specifications of a group budget-based contract: (1) a group budget-fixed contract that provides no remuneration for performance below the budget and a fixed bonus for performance meeting or exceeding the budget, and (2) a group budget-linear contract that provides no remuneration for performance below the budget, a fixed bonus once the budget is attained, plus a piece-rate for production in excess of the budget. We also assigned each group a budget level, set at 50 percent, 75 percent, or 100 percent of the group's performance capability. The results indicate that the group budget-linear contract led to significantly higher group performance than both the group budget-fixed contract and the group piece-rate contract. Additionally, the 75 percent budget level led to significantly higher group performance than both the 50 percent budget level and the 100 percent budget level. Finally, the variability in group performance was lowest under the group budget-linear contract and the 75 percent budget level. Collectively, these results demonstrate the efficacy of both certain types of budget-based contracts and “moderately” difficult budget goals in enhancing group performance. The results also suggest that both motivation and coordination (planning) can be enhanced by budget levels of moderate difficulty and group budget-linear contracts, as the group budget-linear contract and the 75 percent budget level not only led to the highest level of performance, but also led to the lowest variability in performance.
