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...

Most of the recent numerical market equilibrium models of natural gas markets use imperfect competition assumptions. These models are typically embedded with an oversimplified representation of the demand side, usually a single-variable affine function, that does not capture any dynamic...

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...

This paper deals with the optimal enforcement of the competition law between the merger and anti-cartel policies. We examine the interaction of these two branches of the competition policy given the budget constraint of the competition agency and taking into account the ensuing incentives for...

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...

The article analyzes the choices of location of firms from Emerging economies, i.e. Chinese and Indian firms, towards the developed world, Europe taken as a case study. In doing so it put into question the previous postulates based on the requirement of a competitive gap for the advantage of the...
