In addition, the model is developed with a more general utility function.
The study examines the optimal trajectories in human and physical capital and consumption showing the existence of a unique steady state which stability is analyzed. The paper compares the results with the original studies in discrete time.

In this theoretical framework, the prices show a codependency between the two sectors, given by the rate of profit, and inter-industry transactions. In this setup and using discrete time, the model can be represented by a nonlinear two dimensional dynamical system of difference equations of second order. The study shows that the dynamical system admits a unique solution for any initial condition and that there is a unique nontrivial equilibrium. In addition, it can be shown that locally the dynamical system can be represented in the canonical form xt 1 = f(xt) and that the stability of the equilibrium depends on the technological parameters of the production process. Future research includes the extension of the model to the case of several commodities and the closed ...

This sector is composed by agents that face a restriction to the incorporation of new capital, and have the possibility to choose the proportion of its available capital devoted to each of the two goods. These agents have a menu of three strategies to seek to innovate, and thus increase their productivity. The adjustment of these strategies is done endogenously and results in a process that determines the structure of the innovation network. The consideration of public policies in the system leads to the conclusion that the effect of policies depends heavily on the specific population to which they are directed. These results are manifested both in the performance of the system and in the network structure that emerges from the evolution of the model.

More concretely, this rate is assumed to be decreasing over time and a general population growth law verifying this characteristic is introduced. In this setup, the model can be represented by a three dimensional dynamical system which admits a unique solution for any initial condition. It is shown that there is a unique nontrivial equilibrium which is a global attractor. In addition, the speed of convergence to the steady state is characterized, showing that in this framework this velocity is lower than in the original model.

Under the assumptions of certain topologies of interactions and assuming cognitive and informational restrictions, an agent-based model is introduced to analyze the evolution of decisions over time.
The results of the simulations show how social pressures can determine the relationship between individual and social preferences. Societies whose agents have strong individual preferences have outcomes with fragmentation processes that generates a higher number of groups. A minor importance of the individual preferences, results in a smaller proportion of individuals maximizing their individual utility. As well, the quantity of options available and the initial proportion of each alternative are significant variables to determine the proportion of individuals selecting a particular option.
In addition, the study analyses the existence ...

Under the assumptions of certain topologies of interactions and with cognitive and informational restrictions of individuals, we analyze the evolution of these decisions over time by means of an agent-based model.
The results of this work allow us to understand how social processes influence the relationship between individual and social preferences. A greater importance of the individual component implies outcomes with fragmentation processes (a greater number of groups). A minor importance of the individual component results in a smaller proportion of individuals maximizing their individual utility.
This model shows that when individual preferences come into play, even in the case that there is only one variable and two options, a fragmentation and polarization process arise. This is an important difference from the voting model ...
