With a nonlinear investment, the solution of the Kaldor-Kalecki can exhibit a limit cycle solution see for example, Krawiec, Szydlowski,that exhibits oscillations with a constant amplitude depending on the parameters of the equation system.

The numerical economiatas of eqs. The solution is then given now by a limit cycle: When the initial conditions are inside the limit cycle, the amplitude increases to the limit cycle, as shown in Fig.

When the initial conditions are on the limit cycle, the amplitude does not change, as shown in Fig.

When the initial conditions are outside the limit cycle, the amplitude decreases to the limit cycle. When a system is described by two differential difference equations with two variables, it is possible to create an anticipation on one variable and a retardation on the other one, with the method proposed recently Dubois, In considering an anticipated investment depending on the anticipated capital stock, such as.


The first and third equations a-c form a system defined at the current time t, without any time retardation nor anticipation.

With the assumptions, given above:. Simulation of the linear extended Kaldor-Kalecki model ab, with an anticipated investment. The effect of the anticipated investment is to change the phase between the oscillations of the capital stock and the investment.

Financialization and the Stock-Flow Consistent Approach

It could be important to control such a phase in practical business applications. It must be pointed out that the phase shift can be chosen within a range of values: This kalecik deals with the modelling of retardation and anticipation in business models Dubois, b. The oscillatory behaviour of the Kalecki retarded model is only possible because there is a retardation: Secondly, the more general Kaldor-Kalecki model of business cycle is studied in view of showing its anticipatory capabilities.

In this paper, this model is extended to include a new equation giving a computational anticipated capital stock KA tat the current time. Numerical simulations show the feasibility of such a method that can be applied to many other similar problems in all areas of science.

Modelo Kaldor- Kalecki

As explained in Duboisan anticipated event can be computed, at the strong sense, at the condition that another event is defined with a time retardation.

The time retardation may be interpreted as a memory that is a necessary condition for computing a strong anticipation. Recall that a strong anticipation is an anticipation that is computed by the system itself without a predictive model. Recall that an anticipatory system, as defined by Robert Rosenis built on a predictive model of the system, and is thus a weak anticipation. So, the strong anticipation is not simply an extrapolation of the past to the future, but a dynamical behaviour of the system that takes explicitly into account past, present, and future events.

Mathematical foundations of discrete and functional systems with strong and weak anticipations appeared in Dubois, econkmistas. Strong anticipation can be modelled with functional retarded differential equations coupled to an anticipative synchronized equation e.

Voss,Dubois, This paper demonstrates that functional differential equations with both retardation and anticipation are a useful tool for modelling anticipatory systems in a closed form.
