With hedgefunds, managers develop risk management models that mainly aim to play on the effect of de correlation.In order to achieve this goal,companies use the correlation coefficient as an indicator for measuring dependencies existing between(i)the various hedge funds strategies and share...

Consistency, asymptotic normality and e ciency of the maximum likelihood estimator for stationary Gaussian time series, were shown to hold in the short memory case by Hannan (1973) and in the long memory case by Dahlhaus (1989). In this paper, we extend these results to the entire stationarity...

This paper provides a probabilistic and statistical comparison of the log-GARCH and EGARCH models, which both rely on multiplicative volatility dynamics without positivity constraints. We compare the main probabilistic properties (strict stationarity, existence of moments, tails) of the EGARCH...

Emerging economies and especially the BRICS countries have strong economic ties with the euro area. In addition, the financial crisis in the euro area may have effects on other markets or areas, especially those of the main emerging markets. Credit default swap (CDS) spreads are relevant...

In this study, we test the three factor model of Fama and French and the Characteristic Model of Daniel and Titman (1997) on The French Stock Market over July 1976 to June 2001 period. Stocks are ranked by size and book to market ratios and then by ex-ante HML, SMB or Mkt loadings. The...

This paper analyzes the special features of electricity spot prices derived from the physics of this commodity and from the economics of supply and demand in a market pool. Besides mean-reversion, a property they share with other commodities, power prices exhibit the unique feature of spikes in...

This thesis first presents India’s economy and financial system’s recent history and current issues. Then, with an emphasis on the recent turmoil period, it studies the question of financial integration in various markets: equity markets are dealt with in the 1st chapter, CDS spreads are...

L’objet de cette étude est d’évaluer l’impact des décisions des agences de notation (modifications de notation de crédit et les mises sous surveillance de ces notations) sur le prix des actions. Nous concentrons notre étude sur le marché français et comparons nos résultats aux...

This paper contributes to the crucial problem of LIBOR malfunctioning due to its manipulation by banks, a phenomenon described clearly in the FSA Inquiry Report published in September 2012. After applying classical tests of non-stationarity to a series of participating banks’ LIBOR quotes, we...

This article proposes a new empirical methodology for computing a cross-market volatility index - coined CMIX - based on the Factor-Dynamic Conditional Correlation (DCC) model, implemented on volatility surprises. This approach solves problems in treating high-dimensional data and estimating...
