Noise as Information for Illiquidity

We propose a market-wide liquidity measure by exploiting the connection between the amount of arbitrage capital in the market and observed “noise” in U.S. Treasury bonds—the shortage of arbitrage capital allows yields to deviate more freely from the curve, resulting in more noise in prices. Our noise measure captures episodes of liquidity crises of different origins across the financial market, providing information beyond existing liquidity proxies. Moreover, as a priced risk factor, it helps to explain cross-sectional returns on hedge funds and currency carry trades, both known to be sensitive to the general liquidity conditions of the market

Ideals and Boolean Rings: Some Properties

The purpose of this thesis is to investigate certain properties of rings, ideals, and a special type of ring called a Boolean ring

Trait Anxiety Is Associated with Negative Interpretations When Resolving Valence Ambiguity of Surprised Faces

The current research examines whether trait anxiety is associated with negative interpretation bias when resolving valence ambiguity of surprised faces. To further isolate the neuro-cognitive mechanism, we presented angry, happy, and surprised faces at broad, high, and low spatial frequency and asked participants to determine the valence of each face. High trait anxiety was associated with more negative interpretations of broad spatial frequency (i.e., intact) surprised faces. However, the modulation of trait anxiety on the negative interpretation of surprised faces disappeared at high and low spatial frequencies. The current study provides evidence that trait anxiety modulates negative interpretations of broad spatial frequency surprised faces. However, the negative interpretation of low spatial frequency surprised faces appears to be a robust default response that occurs regardless of individual differences in trait anxiety
