We show that immediate and delayed abnormal returns following earnings announcement surprises differ across market states. Immediate abnormal returns are more sensitive to earnings surprises in down markets, while delayed abnormal returns are less sensitive; underreaction is attenuated in down...

The main aim of the thesis is to formulate a concept of liquidity risk and to incorporate liquidity risk in market risk measurement. We first review two types of liquidity risk and the relation between liquidity risk and market risk. To achieve our aim, we use a new framework of portfolio theory...

Numerical computations are performed on a model which has been proposed to describe the characteristic and psychological aspects of financial markets in a pure setting. Overreactions, fluctuations and convergence to realistic values are observed in these calculations. By varying parameters...

Fluctuations in the aggregate balance sheets of financial intermediaries provide a window on the joint determination of asset prices and macroeconomic aggregates. We document that financial intermediary balance sheets contain strong predictive power for future excess returns on a broad set of...

On financial markets, information is a highly demanded resource and processing it to (potentially) generate excess returns drives the activities of many market participants. Not surprisingly, this high relevance of information in markets culminates in a high research interest focusing on how...

Do equity prices efficiently reflect fundamental information as the Efficient Markets Hypothesis suggests? The author challenges a widely held acceptance by financial academicians of the EMH. In a frictionless environment, information acquisition and trading would be costless, transaction prices...

We propose a measure of investors' climate sentiment by performing sentiment analysis on StockTwits posts on climate change and global warming. We find that when investors' climate sentiment is high, emission stocks are relatively overpriced. Moreover, we show that an increase in carbon prices...

High-frequency trading (HFT) has been dominating the activity in developed financial markets in the last two decades. Despite its recent formation, the literature on the impacts of HFT on financial markets and participants is broad. However, there are ongoing debates and unanswered questions...

Using supervisory data from UK central counterparties (CCPs), we study a collateral cycle in which market participants raise liquidity in the repo markets to meet CCPs margin calls, before CCPs reinvest the liquidity through reverse repos as well as bond purchases. In the first leg, we find that...
