In this paper we propose exact likelihood-based mean-variance efficiency tests of the market portfolio in the context of Capital Asset Pricing Model (CAPM), allowing for a wide class of error distributions which include normality as a special case. These tests are developed in the framework of...

In this paper, we provide evidence on two alternative mechanisms of interaction between returns and volatilities: the leverage effect and the volatility feedback effect. We stress the importance of distinguishing between realized volatility and implied volatility, and find that implied...

LOT liquidity model, which is a kind of Tobit model with two unknown censoring points, is commonly used in the literature of microstructure of financial markets to estimate transaction costs and market liquidity from the observed return series. As far as the estimation is concerned, method based...

The consumption-based models have a lack of predictive power for explaining variability of stock returns. This paper examines two well-known models, Campbell and Cochrane (1999)'s habit model and Bansal and Yaron (2004)'s long-run risks model, to see whether they produce a significant power of...

We clarify that the widely used estimation method for the LOT liquidity model in the market microstructure literature is improper in the sense of econometric inference. Based on an extensive simulation study and a real data analysis, we show that this method not only overestimates the true...

This article introduces the rough path-dependent volatility (RPDV) model, a model structurally adapted to jointly capture two major empirical features of volatility: its rough behavior and its path-dependence.After presenting it in its general form and its link with other existing models in the...

We re-examine US mutual fund performance persistence. We investigate persistence (i) using both “academic” factor models and “practitioner” index models, (ii) using decile-size recursive portfolios and also portfolios formed from smaller numbers of funds, (iii) using nonparametric...

This presentation introduces the rough path-dependent volatility model (RPDVM). After defining the model and its different components, the presentation focuses on various specifications of the RPDVM that already exist in the literature. Finally, a Markovian approximation of the model is presented

This paper analyses the tax shield under realistic assumptions: no immediate refund and potential corporate bankruptcy for different financing policies. Assuming a German setting, we additionally investigate the impact of the interest ceiling (“Zinsschranke”) introduced by the German Tax...

It is common belief that Exchange Traded Derivatives (ETDs), e.g. Futures and Futures Options, are collateralized plain vanilla financial instruments carrying low counterparty risk and capital requirements with respect to corresponding Over The Counter Derivatives (OTCDs). In this paper we...
