In this paper we develop a financial market model based on continuous time random motions with alternating constant velocities and with jumps occurring when the velocity switches. If jump directions are in the certain ...

We consider a discrete-time financial model in a general sample space with penalty costs on short positions. We consider a friction market closely related to the standard one except that withdrawals from the portfolio value ...

In this paper we develop a financial market model based on continuous time random motions with alternating constant velocities and with jumps occurring when the velocity switches. If jump directions are in the certain ...

Semi-arid regions are characterized by high temporal and spatial variability of precipitation, resulting in high uncertainty in their estimation. This fact has a dramatic impact on the decisions taken to allocate water ...

The purpose of this work is to present a simplified approach of evaluating the efficacy of the coverage for a net investment in foreign currency within the hedging accounting with a derivative financial instrument, a ...

Considering the high representation of soybeans in economic activity in the State of Mato Grosso, this study examines the risk that arises from the search for protection against fluctuations in future trading prices of ...

Irradiance received within the olive hedgerow canopy varies with respect to row orientation, spacing and hedge dimensions. These orchard management criteria offer the opportunity for improving productivity based on ...

The paper develops a new class of financial market models. These models are based on generalized telegraph processes: Markov random flows with alternating velocities and jumps occurring when the velocities are switching. ...
