Abstract
Disputes over penalties for breaching a contract are often resolved in court. A simple model illustrates how inefficient courts can sway public buyers from enforcing a penalty for late delivery in order to avoid litigation, thereby inducing sellers to delay contract delivery. By using a large dataset on Italian public procurement, we empirically study the effects of court inefficiency on public work performance. Where courts are inefficient, we find the following: public works are delivered with longer delays; delays increase for more valuable contracts; contracts are more often awarded to larger suppliers; and a higher share of the payment is postponed after delivery. Other interpretations receive less support from the data.
