We show that aversion to risk and ambiguity leads to information inertia when investors process public news about assets. Optimal portfolios do not always depend on news that is worse than expected; hence, the equilibrium stock price does not reflect this bad news. This informational inefficiency...

Purpose This paper examines whether there are differences in the nature of the price discovery process across established versus emerging stock markets using a twenty-country sample. Design/methodology/approach The authors analyse security returns for traces of predictability or non-randomness...

Sheng and Thevenot (2011) develop a new measure of uncertainty which is a modification of the uncertainty measure advanced by Barron, Kim, Lim and Stevens (BKLS 1998), and they find this new uncertainty measure to be superior to the BKLS measure in certain settings. We follow Sheng and...

In empirical tests guided by recent theory (e.g., Hughes, Liu and Liu 2007; and Lambert, Leuz and Verrecchia 2012), we examine the joint effects of information asymmetry and information precision on the cost of capital and how these effects vary based on the amount and quality of available...

We propose a new approach to measuring informed trading in individual securities based on a portfolio optimization model for investors facing information and liquidity shocks. These shocks induce speculative and liquidity-motivated order flow, taking into account the price impact of trading. The...

I examine the possibility of information-based trading in a multiperiod consumption setting. I develop a necessary and sufficient condition for trade to occur. Intertemporal substitution introduces a desire to correlate current consumption with future aggregate shocks. When agents have...

We propose the Volume Coefficient of Variation (VCV), the ratio of the standard deviation to the mean of trading volume, as a new and easily computable measure of information asymmetry in security markets. We use a microstructure model to demonstrate that VCV is strictly increasing in the...

This paper studies an asset market where, as in major world exchanges, informed and liquidity investors continuously control the timing of orders and whether to take or provide liquidity. In equilibrium, investors demand and supply liquidity simultaneously, following distinctive time-varying...

We examine the role of earnings management in explaining the properties of asset prices and stock market participation. We demonstrate that investors' uncertainty about the extent of manipulation can cause excess movements in stock price relative to fluctuations in output. When faced with...

In empirical tests guided by recent theory (e.g., Hughes, Liu and Liu 2007; and Lambert, Leuz and Verrecchia 2011), we examine the joint effects of information precision, information asymmetry and the level of market competition on firms' cost of equity capital. Consistent with theory, we find that...
