The Ricardian dynamics describe the substitution of a new marginal method for an outgoing marginal method when demand increases. The process of extension or intensi…cation of cultivation allows for spasmodic changes in prices and rents but is smooth on the physical side. We criticize the notion...

In the crude oil market the phenomenon of Long Memory can be easily identified with the help of the simple (but effective) methodology of Katsumi Shimotsu. The Exact Local Whittle estimator and two testing strategies provide a strong assessment of the phenomenon. We present evidences and we...

Levy and Roll (Review of Financial Studies, 2010) have recently revived the debate related to the market portfolio's efficiency suggesting that it may be mean-variance efficient after all. This paper develops an alternative test of portfolio mean-variance efficiency based on the realistic...

This paper investigates the relationship between trading volume and price volatility in the crude oil and natural gas futures markets when using high-frequency data. By regressing various realized volatility measures (with/without jumps) on trading volume and trading frequency, our results...

This paper elaborates on a basic model of mass tort litigation, highlighting the existence of positive informational externalities a¤orded by the discovery process (as a general technology of production of evidences) in order to study when a class action is formed, or when a sequence of...
