This paper examines the spillovers of the sanction procedures on listed companies which were victims of others' financial regulatory breaches (i.e. regulated entities or individuals). Market manipulators can be investigated and possibly sanctioned for doing so, according to the French...

We replicate the study of Tabak & Cajueiro (2007): "Are the crude oil markets becoming weakly efficient over time? A test for time-varying long-range dependence in prices and volatility" published in Energy Economics 29, pp. 28-36. The results have been mostly confirmed. Specifically, we have...

This paper assesses the information content of sanctions of listed companies pronounced by the French Financial Market Authority, through reactions from financial markets over the period 2004 to 2016. We answer whether, for a listed company, being named in a sanction report, as an offender, an...

This article introduces a new measure of stock market efficiency. The measure specifies how much a stock market index deviates from Brownian motion and is computed from frequency representations of isoquantile shapes estimated from lagged index returns. We describe the theory behind the...

Isobar surfaces, a method for describing the overall shape of multidimensional data, are estimated by nonparametric regression and used to evaluate the efficiency of selected markets based on returns of their stock market indices. -- Isobars ; efficient market hypothesis ; nonparametric...

We examine how the publication of intentional financial crimes committed by listed firms is interpreted by financial markets, using a systematic and quantitative review of existing empirical studies. Specifically, we conduct a meta-regression analysis and investigate the extent and nature of the...

I collect 1,186 reported estimates of long-run value creation from 49 studies and present the first meta-analysis of the literature on shareholder activism and its effect on firm value in the longrun. This synthesis is necessary because shareholder activism is increasing over time and across...

Shareholder activism constitutes an increasingly prominent feature of corporate governance landscape. There is a controversy in prior research over whether and how much value activism creates. We examine whether estimates of the impact of shareholder activism are published selectively in prior...

We develop a four-factor model intended to capture size, value, and credit rating transition patterns in excess returns for a panel of predominantly mid- and large-cap entities. Using credit transition matrices and rating histories from 48 US issuers, we provide evidence to support a...

This paper investigates the impact of volatility in the upstream electric vehicles (EV) battery raw materials market on the downstream stock returns of individual EV producers. The study uses the daily stock returns of two lithium producers and the newly proposed EGARCH-EARJI model to capture...
