We show how to minimize the asymptotic variance of multipower estimators using a linear combination of optimal powers. Taking advantage of the lower variance provided by this technique allows to build superior estimators of integrated volatility powers. In particular, we focus on a new efficient...

This paper sheds new light on the liquidity dynamics of the credit default swaps (CDS) market in Europe around the Subprime crisis. Based on an original dataset of 94 European companies from 2005 to 2009, we use a panel regression analysis to study the relationship between CDS premiums and...

Our study aims to bridge the gap between contemporary studies on financial cycles and the financial instability hypothesis in the form of a Minsky cycle (Minsky, 1963). Paper contribution range from explored causality links (financial cycles cause business cycles) to the empirical estimation of...

Investors seek to hedge against interest rate risk by taking long or short positions on bonds ofdifferent maturities. We study changes in risk taking behavior in a low interest rateenvironment by estimating a market stochastic discount factor that is non-linear and thereforeconsistent with the...

This paper characterizes the dynamics of jumps and analyzes their importance for volatility forecasting. Using high-frequency data on four prominent energy markets, we perform a model-free decomposition of realized variance into its continuous and discontinuous components. We find strong...

We provide a theoretical basis for understanding the properties of compound returns. At long horizons, multiplicative compounding induces extreme positive skewness into individual stock returns, an effect primarily driven by single-period volatility. As a consequence, most individual stocks...

In an environment of near-zero yields for traditional asset classes and tightening bank regulation, debt in privately arranged loans has become an interesting alternative to publicly distributed bonds for borrowers and professional investors. Key questions for potential investors concern the...

This paper analyzes the evolution of Australian property prices, the relationships between cities, houses and units, the stock market and monetary policy. Using monthly house and unit prices for all eight capital cities we identify extended periods of explosive positive price changes followed by...

This paper examines inflation and the role of inflation-hedging assets in an institutional portfolio. Even in the current environment of low realized inflation, inflation risk remains, in the form of inflation surprises, which have historically been damaging for equity and bond portfolios....

We survey the nascent literature on machine learning in the study of financial markets. We highlight the best examples of what this line of research has to offer and recommend promising directions for future research. This survey is designed for both financial economists interested in grasping...
