Do discounts mitigate numerological superstitions? Evidence from the Russian real estate market

In this paper I investigate the impact of numerological superstitions and discounts' effect on the buyers' behavior in the apartment market using actual sales data. Based on the dataset from Moscow primary real estate market, which includes 40 buildings, we test the apartments buyers' demand on lucky 7th floor and unlucky 13th floor in comparison to neighboring floors and its response to developers' discount policy for the apartments on the 13th floor. Results of the random-effects model for the preference towards 7th floor show that that "good luck" effect is present at the 90% confidence interval. Results of the mixed-effects model for the preference towards the 13th floor's apartments show that in case of discount moderation, the "bad luck" effect of the 13th floor is mitigated, while in case of "no discount" buildings we find the clear negative effect of the 13th floor.
