We introduce a new model in order to describe the fluctuation of tick-by-tick financial time series. Our model, based on marked point process, allows us to incorporate in a unique process the duration of the transaction and the corresponding volume of orders. The model is motivated by the fact...

In this note, we cast a Hawkes process-based order book model into a markovian setting and; using techniques from the theory of Markov chains and stochastic stability, show that the order book is stable and leads to a diffusive price limit at large time scales.

We rely on high frequency data to explore the joint dynamics of underlying and option markets. In particular, high frequency data make observable the realized variance process of the underlying, so its effects on option price dynamics are tested. Empirical results are confronted with the...

Theoretical and historical experience suggests a financial centre may either include a single, consolidated and loosely regulated stock exchange attracting all intermediaries and actors, or a variety of exchanges going from strictly regulated to completely unregulated and adapted to the needs of...

We rely on high frequency data to explore the joint dynamics of underlying and option markets. In particular, high frequency data make observable the realized variance process of the underlying, so its effects on option price dynamics are tested. Empirical results are confronted with the...

Douglass North, along with Ronald Coase and Oliver Williamson, transformed the early intuitions of new institutional economics into powerful conceptual and analytical tools that spawned a robust base of empirical research. NIE arose in response to questions not well explained by standard...

In this paper, I focus on the extension of transaction costs to appropriative activity and coercive power in the property rights approach. It has been argued that including the costs of appropriation and violent enforcement in transaction costs is based on the assumption that Coaseian bargaining...

New Institutional Economics, based on the Coasean comparative approach, offers a highly useful framework for research on environmental problems. We propose a tentative analytic framework for environmental problems and we try its heuristic power by first applying it to the Poitou-Charentes...

In this paper we deal with a utility maximization problem at finite horizon on a continuous-time market with conical (and time varying) constraints (particularly suited to model a currency market with proportional transaction costs). In particular, we extend the results in Campi and Owen (2011)...
