    "abstract": "Gambling is one of the basic economic activities that humans indulge in. An\ninvestigation of gambling activities provides deep insights into the economic\nactions of people and sheds lights on the study of econophysics. In this paper\nwe present an analysis of the distribution of the final odds of the races\norganized by the Japan Racing Association. The distribution of the final odds\n$P_o(x)$ indicates a clear power law $P_o(x)\\propto 1/x$, where $x$ represents\nthe final odds. This power law can be explained on the basis of the assumption\nthat that every bettor bets his money on the horse that appears to be the\nstrongest in a race.",
