Traders differ in speed and their speed differences matter. I model strategic interactions induced when high frequency traders (HFTs) have different speeds in an extended Kyle (1985) framework. HFTs are assumed to anticipate incoming orders and trade rapidly to exploit normal-speed traders'...

This paper investigates competitiveness in the Ukrainian stock market during local crisis of 2013–2015. The following hypothesis is tested: crisis decreases competitiveness in the stock market. The analysis is carried out for the most liquid stocks in the Ukrainian Exchange (UX) over the...

In this paper we survey the theoretical and empirical literatures on market liquidity. We organize both literatures around three basic questions: (a) how to measure illiquidity, (b) how illiquidity relates to underlying market imperfections and other asset characteristics, and (c) how...

Economic expectations play a central role in financial markets, yet investors often disagree about the economy's future. This disagreement has long been viewed as a potential driver of asset prices, but it remains unclear whether it reflects mispricing or a priced source of risk. We address this...

Revisions of consensus forecasts of macroeconomic variables positively predict announcement day forecast errors, whereas stock market returns on forecast revision days negatively predict announcement day returns. A dynamic noisy rational expectations model with periodic macroeconomic...

We investigate the disclosure and prominence of non-GAAP earnings metrics in IPO prospectuses and how these disclosures affect IPO valuation. In contrast to already-public firms, we find an inverted U-shaped relation between IPO firms' GAAP performance and the likelihood that they will disclose...

We explore the possibility that overnight returns can serve as a measure of firm-specific investor sentiment by analyzing whether they exhibit characteristics expected of a sentiment measure. First, we document short-term persistence in overnight returns, consistent with existing evidence of...

Can prices convey information about the fundamental value of an asset? This paper considers this problem in relation to the dynamic properties of the fundamental (whether it is constant or time-varying) and the structure of information available to agents. Risk-averse traders receive two...

Despite accounting conservatism and indicating the firm's required return exceeds its return on equity, equity book values greater than market values (BTM 1) are not rare. The question we address is why. We find BTM 1 is pervasive and persistent. More importantly, BTM 1 is not attributable to...

We study the effect of ambiguity on the formation of bubbles and on the occurrence of crashes in experimental asset markets à la Smith, Suchanek, and Williams (1988). We extend their framework to an environment where the fundamental value of the asset is ambiguous. We show that, when the...
