L'étude du modèle à trois facteurs en présence des comoments d'ordres trois et quatre dans le cadre du marché français fait l'objet de cet article. Le pouvoir explicatif des portefeuilles de marché, HML et SMB est testé en présence des portefeuilles de co-skewness et de co-kurtosis. À...

We develop a geographical-based vibrancy index using important location characteristics that measure local economic health. We show that local vibrancy is associated with future firm outcomes, including investment, leverage, profitability, and firm value. More vibrant firms are located in...

This study assesses the effect of financial development on income inequality in Côte d'Ivoire, using a multidimensional indicator of financial development that incorporates financial inclusion. We use ARDL and quantile regression methods to regress income inequality (measured by the Gini index)...

This paper argues in an Austrian-Business Cycle's perspective that all the conditions are met again to have new crisis. The Federal Bank treats, always, a crisis of liquidity excess by low interest rate, i.e. "cheap money policy". When Federal Bank will have to rise its rates, the crisis will...

We apply several recently proposed tests for structural breaks in conditional variance and covariance dynamics. The tests apply to both the class of ARCH and SV type processes and allow for long memory features. We also apply them to data-driven volatility estimators using high-frequency data...
