Overview

Abstract (English)

Previous research shows that mood-altering events, such as sports results, elections outcomes and natural disasters, impact fertility, crime rate, and investor behaviour. In this paper, we use recent Canadian Birth Statistics and the National Hockey League (NHL) results to examine the link between sports events and short-term fertility spikes. In addition, using betting odds, we differentiate among unexpected wins, unexpected losses, and expected outcomes, as a test for the relevance of the Prospect Theory to this context. Our dataset is a daily panel, following all the seven Canadian Census Metropolitan Areas with a team in the NHL, from 2008 to 2019. In our panel fixed effects estimations, we account for the day of the week and all statutory federal and provincial holidays of Canada. In the estimations with raw NHL results, the coefficients of interest ultimately lose their statistical significance. In the specifications accounting for expectations, we find a statistically significant association with fertility for unexpected wins, and statistically insignificant coefficients for unexpected losses as well as expected NHL outcomes. In light of the results, we propose the greater likelihood of pre-game social gatherings on sports nights and celebratory sex after the euphoria of an unexpected win, as the possible channels of impact.
