The Effect of Payment Delays on Stock Prices

In this paper stock returns are modeled as a function of payment delays. Three hypotheses are tested: (1) that buyers compensate sellers for a six-business-day payment delay; (2) that the rate of compensation is the riskless rate; and (3) that this delay is solely responsible for day-of-the-week effects. Results support the first and second hypotheses, but not the third. The coefficient on the variable that controls for payment delays is correctly signed and statistically significant. It is the correct size in all periods but one. However, the estimated rate of compensation probably differs across days of the week. Finally, controlling for a six-business-day payment delay fails to eliminate the weekly pricing pattern.
