We introduce a general binomial model for asset prices based on the concept of random maps. The asymptotic stationary distribution for such model is studied using techniques from dynamical systems. In particular, we present a technique to construct a general binomial model with a predetermined...

The field of risk theory has traditionally focused on ruin-related quantities. In particular, the socalled Expected Discounted Penalty Function has been the object of a thorough study over the years. Although interesting in their own right, ruin related quantities do not seem to capture...

This paper analyzes deforestation in areas of overlapping land tenure in the northern Ecuadorian Amazon. We use a random coefficients model to test for differences in forest cover across tenure forms over time. Tenure categories are significantly associated with changes in deforestation, even...

The Expected Discounted Penalty Function (EDPF) was introduced in a series of now classical papers ([9], [11] and [12]). Motivated by applications in option pricing and risk management, and inspired by recent developments in fluctuation theory for Lévy processes, we study an extended definition...
