This paper explores commonality in liquidity for country ETFs. Using data from 21 country ETFs, the empirical results present the strong commonality in liquidity among country ETFs. Furthermore, the paper shows that the magnitude of commonality in liquidity for country ETFs varies with the...

Short sellers are routinely blamed for destabilizing stock markets by exacerbating deviations from fundamental values. In response, regulators periodically impose short sale constraints aimed at preventing excessive stock market declines. One explanation is that policy makers regard short...

This paper aims at testing for time-variations in herd behavior in stock markets. In particular, we analyze how investors’ behavior differs between times of market turmoil and tranquil trading periods. Thereby, we take into account herding within a certain market as well as international...

We show how the timing of financial innovation might have contributed to the mortgage boom and then to the bust of 2007-2009. We study the effect of leverage, tranching, securitization and CDS on asset prices in a general equilibrium model with collateral. We show why tranching and leverage tend...

This paper presents a tractable model of non-linear dynamics of market returns using a Langevin approach.Due to non-linearity of an interaction potential, the model admits regimes of both small and large return fluctuations. Langevin dynamics are mapped onto an equivalent quantum mechanical (QM)...

We find that stock price crash risk is positively associated with lagged equity lending fee and fee risk. This positive relation is stronger for the stocks with a lower short interest level and higher information uncertainty. Our results are robust to using alternative measures of price crash...

This paper investigates the role of volatility risk on stock return predictability specified on two global financial crises: the dot-com bubble and recent financial crisis. Using a broad sample of stock options traded at the American Stock Exchange and the Chicago Board Options Exchange (CBOE)...

In a sample of U.S. stocks, higher stock lending fees predict significantly lower excess returns beyond shorting demand and loan supply. This relation is stronger after October 2008 which is likely attributable to a regime shift in the lending market with the onset of the Global Financial...

We present a microfounded New Keynesian model that features financial vulnerabilities. Financial intermediaries' occasionally binding value-at-risk constraints give rise to variation in the pricing of risk that generates time-varying risk in the conditional mean and volatility of the output gap....

Purpose – The intervalling effect bias of beta refers to the sensitivity of beta estimation with respect to the reference time interval on which returns are measured and its manifestation may indicate the degree of market inefficiencies. The purpose of this paper is to study the intervalling...
