Hi, I am a horse-lover and undergraduate economics major at Yale University writing a research paper on racing. I am focusing on how changes in the gambling industry as a whole (development of online gambling, increased legalization of sports gambling, racinos, etc.) have impacted the economic aspects of the sport. In particular, I am interested to see if there have been any substantial changes in breeding practice. In my research I have obviously found a lot of articles about a supposed shift in breeding focus away from strength and stamina and towards pure speed. I would really like to speak with someone in the know about this and other changes in the industry (particularly, changes due to economic or societal factors outside the sport). Please let me know if you have any insight.
