Perishable products traded in informal markets might be subject to price variations in two opposite directions. Whereas the absence of posted prices opens the door for price discrimination based on some buyers’ attributes, the reduction in quality over time might decrease prices to secure a transaction. We use an audit experiment to detect these pricing patterns in the informal flower markets nearby the cemeteries of Bogota, Colombia. We analyze 441 price quotations. We interpret the lower prices in the afternoon than in the morning as evidence of dynamic pricing. Regarding price discrimination, we find that women are quoted a higher price than men, whereas attire (formal versus informal) does not affect prices. The price variations associated with the time of the day and the gender of the buyer appear to be independent of each other.
