PORTFOLIO OPTIMIZATION IN AFFINE MODELS WITH MARKOV SWITCHING [PDF]
We consider a stochastic-factor financial model wherein the asset price and the stochastic-factor processes depend on an observable Markov chain and exhibit an affine structure. We are faced with a finite investment horizon and derive optimal dynamic investment strategies that maximize the investor's expected utility from terminal wealth.

Optimal Control with Partially Observed Regime Switching: Discounted and Average Payoffs
We consider an optimal control problem with the discounted and average payoff. The reward rate (or cost rate) can be unbounded from above and below, and a Markovian switching stochastic differential equation gives the state variable dynamic.

A Markov Switching Autoregressive Model with Time-Varying Parameters
This study showcased the Markov switching autoregressive model with time-varying parameters (MSAR-TVP) for modeling nonlinear time series with structural changes. This model enhances the MSAR framework by allowing dynamic parameter adjustments over time.

Risk Management of Selected Products Imported by Iranian Agriculture Using quasi-futures contracts [PDF]
The present study aims to provide a model for covering price risks in Iranian importers of agricultural commodities. In order to assess the efficiency of the model, daily spot and futures prices of soybeans and corn were collected from the Chicago ...

Time Varying Transition Probabilities for Markov Regime Switching Models [PDF]
We propose a new Markov switching model with time‐varying transitions probabilities. The novelty of our model is that the transition probabilities evolve over time by means of an observation driven model. The innovation of the time‐varying probability is generated by the score of the predictive likelihood function. We show how the model dynamics can be

In this paper, we consider the dynamics of a stochastic Gilpin–Ayala model with regime switching and impulsive perturbations. The Gilpin–Ayala parameter is also allowed to switch.
