In this paper, we present a discrete time regime switching binomial-like model of the term structure where the regime switches are governed by a discrete time semi-Markov process. We model the evolution of the prices of zero-coupon when given an initial term structure as in the model by Ho and...

In analogy with standard derivation of Tsallis factor in non extensive statistical mechanics, we find the wealth distribution for an economic agent in a conservative exchange market. Tsallis entropic index distinguish between two different regimes, the large and small size market. The Pareto...
