This article evaluates patents in a stochastic discrete time framework following the real options approach. By modeling the dynamics of the underlying as a spatial point process both size and time of the jumps can be treated as random variables. The propagation of the jumps from the underlying...

This paper provides a theoretical fractional cointegration analysis in a nonparametric framework. We solve a generalized eigenvalues problem. To this end, a couple of random matrices are constructed taking into account the stationarity properties of the differencesof a fractional p-variate...

Virtually all governments seek to fight tax evasion exploiting better and better technological devices. Despite of that the phenomenon still remains alive and kicking all around the world. The foregoing naturally arises the question in the title. This paper develops a simple model to provide...
