This paper describes the strategies used by AstonCAT-Plus, the post-tournament version of the specialist designed for the TAC Market Design Tournament 2010. It details how AstonCATPlus accepts shouts, clears market, sets transaction prices and charges fees. Through empirical evaluation, we show that AstonCAT-Plus not only outperforms AstonCAT (tournament version) significantly but also achieves...

noise-induced hearing loss (nihl) is the most common complication of long-term noise exposure, though there  are  some  other  complications  due  to  exposure  to  noise.  metabolic  complications  of  the  noise exposure are being evaluated in recent studies. we aimed to assess the relationship between nihl and lipid profile, and fasting blood sugar (fbs). in this cross-sectional  study, 462 ...

In this paper we study the design and characterization of prediction markets in the presence of traders with unknown risk-aversion. We formulate a series of desirable properties for any “market-like” forecasting mechanism. We present a randomized mechanism that satisfies all these properties while guaranteeing that it is myopically optimal for each trader to trade honestly, regardless of her de...

background: this paper describes the common hazards in the metal industry – chemicals and noise. the aim of the study was to get an overview of risk levels of mentioned occupational hazards and examine the implementation of adequate safety measures. methods: measurements of noise and chemicals were performed, self-reported exposure and usage of personal protective equipment from workers were us...

Purpose – The purpose of this paper is to consider the influence of individual risk preferences on the effectiveness of incentive pay schemes, by examining the link between individual effort and risk aversion in situations where outcome uncertainty multiplies with effort. Such “multiplicative noise” situations are common, occurring whenever payment is awarded per success rather than per attempt...

Information markets are low volume markets whose prices offer informative estimates on particular policy topics of interest. Observers have expressed concern that such prices might be less informative due to manipulators, i.e., traders who prefer that we see some policy estimates instead of others. We adapt a Kyle-style market microstructure model to the case of information markets, by assuming...
