This paper provides a closed-form solution for the price-dividend ratio in a standard asset pricing model with stochastic volatility. The solution is useful in allowing comparisons among numerical methods used to approximate the non-trivial closed-form

We develop a new method for computing minimal state variable solutions (MSV) to Markov-switching rational expectations models. We provide an algorithm to compute an MSV solution and show how to test a given solution for uniqueness and boundedness. We construct an example that is calibrated to...

In this paper we apply a general model of one-sided and two-sided platform businesses to a collusive framework which we model as joint profit maximization. We have a particular interest in how the social loss and other metrics depend on the strength of the network (direct or indirect) effect. We...

In this paper we apply a general model of one-sided platform businesses to a duopoly competitive framework. We have a particular interest in how the option of multi-homing affects the competitive dynamic. We find that if multi-homing is precluded, the incumbent platform is always able to...

The impact of transaction costs on asset pricing in equilibrium is rarely studied. We study an equilibrium model with proportional transaction costs where two investors trade in a derivative to hedge non-traded endowments. For any positive transaction cost there always exist no trade equilibria....

This paper presents a Solow Growth Model with the labor force ruled by the logistic equation added by a constant migration rate, I. We prove the global asymptotic stability of the capital and production per capita. Considering a Cobb-Douglas production function, we show this model to have a...

This paper develops a non-stochastic sovereign-debt dynamic model, with increasing cost of capital. It finds that there are parameters for which there is a stable fixed borrowing level, and there are parameters for which the model depicts the case of serial defaulters. Levels of debt that tend...
