For financial assets whose best quotes almost always change by jumping by the market’s price tick size (one cent, five cents, etc.), this paper proposes an estimator of Quadratic Variation which controls for microstructure effects. It measures the prevalence of alternations, where quotes jump back to their just-previous price. It defines a simple property called “uncorrelated alternation”, whic...

When Nasdaq market makers avoid odd-eighth quotes, bid-ask spreads are large and decline dramatically with exchange listing. When market makers use both odd and even eighths. spreads are smaller and decline only slightly with exchange listing The large spreads observed when Nasdaq market makers avoid od...

We propose a method for using neural networks to attribute quotes in literary texts. Since previous work has been unable to successfully solve this problem based on bag-of-words features, we study the issue of whether this is due to the limited expressiveness of such features. By re-framing the modeling of quotes and characters as based off of word vectors, we hope to demonstrate that individua...

Exploring a possible correlation between the efficient price and the noise, as HL do, is an exciting and challenging task. By examining the volatility signature plots of trades and quotes, HL report that RV estimates based on quotes at very high frequency decrease. This is different from many earlier findings on volatility signature plots based on transaction prices. It is important to figure o...
