This paper proposes conditions for the existence and uniqueness of solutions to systems of linear differential or algebraic equations with delays or advances, in which some variables may be non-predetermined. These conditions represent the counterpart to the Blanchard and Kahn conditions for the...

In this paper we model the conflict between the group of polluting firms of a country and the social planer of the same country which attempts to control the volume of emissions generated during the production process. Both players of the game have their own control policies which are the rate...

We explore bifurcation phenomena in the open-economy New Keynesian model developed by Clarida, Gali and Gertler (2002). We find that the open economy framework can bring about more complex dynamics, along with a wider variety of qualitative behaviors and policy responses. Introducing parameters...

This paper investigates the identification, the determinacy and the stability of ad hoc, "quasi-optimal" and optimal policy rules augmented with financial stability indicators (such as asset prices deviations from their fundamental values) and minimizing the volatility of the policy interest...

This paper analyzes the solution of linear mixed-type functional differential equations with either predetermined or non-predetermined variables. Conditions characterizing the existence and uniqueness of a solution are given and related to the local stability and determinacy properties of the...

This note provides some examples of plant leaves whose outline maps exhibit Poincaré recurrence and mixing while subjected to repeated Anosov diffeomorphic transformation. The datasets and a computer program (Fortran 77) have also been given.

We explore bifurcation phenomena in the open-economy New Keynesian model developed by Gali and Monacelli (2005). We find that the open economy framework brings about more complex dynamics, along with a wider variety of qualitative behaviors and policy responses. Introducing parameters related to...

In this paper, the basic assumption is that the environment provides two different kinds of services. First, the environment may serve as an input to the production of conventional goods. For example, the exploitation of an oil source from which one firm extracts the oil which in turn is used as...

In this paper we set up an oligopolistic market model, where firms invest in pollution abatement in order to increase the whole market size via an increase in the consumers’ reservation price. Moreover, we suppose that the demand function is not a linear one and the resulting game is not a...

Traditional economic theory, up to the middle of the twentieth century, builds up the production functions regardless of the inputs’ scarcity. In the last few decades it has become clear that in many cases inputs are depletable quantities and at the same time a lot of constraints are imposed...
