There have been many attempts, theoretical and empirical, to explain the persistence of a favorite-longshot bias in various horse betting markets. Most recently, Snowberg and Wolfers (2010) have shown that the data for the US markets support a “misperceptions of probability” approach in line...

In general, models in finance assume that investors are risk averse. An example of such a recent model is the pioneering work of Aumann and Serrano, which presents an economic index of riskiness of gambles which is independent of wealth and holds (as might be understood from the adjective...

The paper presents a game-theoretical model to examine the equilibrium timing of insider trades in a market with a finite life span. An example of such a market is that for horse betting, where insiders must bet before the race or their information is of no value. We show that there is no...

Prediction markets have been shown to generate fairly accurate odds of various events occurring in the future. The forthcoming possibility of natural disasters provides, on occasion, an opportunity for a bet, yet no wide scale and accepted prediction market has arisen despite its obvious...

In this article, the authors test two different kinds of bias—the favorite-long shot/favorite-underdog bias and the home team bias—and distinguish between the two, using a distinctive feature of the Australian Football League (AFL): the fact that many games are played on neutral...

Standard methods to assess the statistical quality of econometric models implicitly assume there is only one person in the world, namely the forecaster with her model(s), and that there exists an objective and independent reality to which the model predictions may be compared. However, on many...

The authors develop a model of strategic work interactions in collective enterprises explaining the following observation: the Israeli kibbutz, in which net collective output is distributed equally, has been an economic success, while the Soviet kolkhoz, in which net output traditionally was...

Inside information concerning a risky asset is presumed to be beneficial to its holder. Measurement of the impact and benefit of inside information is difficult because its use for financial gain is often illegal. Ideally one would like to investigate and compare two mutually isolated groups,...
