This work aims to initiate a reflection on the awareness of environmental, social, and corporate governance issues, summarized in the acronym ESG (Environmental, Social, Governance), among Italian SMEs. The integration of ESG issues into business models has led to an expansion of the risk...

Evidence suggests that arbitragers exchange investment ideas. We analyze why and under what circumstances sharing occurs. Our model suggests that sharing ideas will lead to the following: more efficient asset prices, larger arbitrager profits, and correlated arbitrager returns. We predict that...

We analyze commonality in informed trading across stocks, and how informed trading varies with the structural and trading characteristics of a firm. We thereby isolate the residual level of informed trading that is unrelated to commonality, trading characteristics, and structural...

We review the theories on how liquidity affects the required returns of capital assets and the empirical studies that test these theories. The theory predicts that both the level of liquidity and liquidity risk are priced, and empirical studies find the effects of liquidity on asset prices to be...

This paper analyses the intraday co-movements between returns on several commodity markets and on the stock market in the United States over the 1997-2011 period. By exploiting a new high frequency database, we compute various rolling correlations at (i) 1-hour, (ii) 5-minute, (iii) 10-second,...

We propose a novel approach to cross-sectional equities sample selection, derived from best market practice in index construction and focused on investability. Using the U.K. market as a template, we first demonstrate how the popular Datastream dataset is plagued by data deficiencies that would...

Securities Transaction Taxes have received much attention over the last few years with countries and global organizations trying to control the level of speculations, especially since the Global Financial Crisis. This study examines the impact of an increase in the level of securities...

Contrary to existing event studies around option listing introductions, we show short selling and options trading are complements, rather than substitutes. Further, while a plethora of literature demonstrates both short sellers and option traders are informed traders, relatively little is known...

We design an experiment to study the implications of information networks for the incentive to acquire costly information, market liquidity, investors' earnings and asset price characteristics in a financial market. Social communication crowds out information production as a result of agent's...

The theory of fair geometric returns, F theory for short, rejects the generally accepted notion that volatility is the risk of risky assets. Instead, it claims that capital market volatility, in turn, constitutes the maximum achievable geometric return. In order to get to the point, F theory, in...
