Full-text available
This paper fits in the theory of international agreements by studying the success of stable coalitions of agents seeking the preservation of a public good. Extending Baliga and Maskin, we consider a model of N$$ N $$ homogeneous agents with quasi‐linear utilities of the form uj(rj;r)=rα−rj$$ {u}_j\left({r}_j;r\right)={r}^{\alpha }-{r}_j $$, where r...

Full-text available
In this article, we present an evolutionary model that shows the possibility of political cycles in which populist and non-populist elites alternate in power. The platforms promoted by populist politicians are presented as alternatives to solve pressing problems that afflict society, without paying attention to the economic or social imbalances tha...
Article
In this work we analyze, from the perspective of game theory, the interaction between the ruling elite, the opposition (to the government) and citizens during electoral times. In particular, we focus on the role that corruption plays (understood in a broad sense) in both contenders, government and opposition, and the level of information on the par...

In this paper we study a repeated game and the replicator dynamics to analyze the spread of a rumor in a society formed by two populations. One population is informed about a rumor and communicates the rumor to the other population. According to the preferences of each individual, this rumor is communicated in its original or in a modified form. We...
Article
The goal of this research is to study an economic system characterized by the coexistence of tax evading citizens with corrupt auditors (public officials), that is a system of predators-preys, i.e. corrupts and not, evaders and not. We show that citizens choose non-corrupt behavior when their utility exceeds a threshold level with respect to an opt...
Article
Full-text available
We study an evolutionary dynamics for the contributions by agents to a common/public good in a generalized version of Baliga and Maskin’s environmental protection model. The dynamical equilibria consist of three scenarios: a single agent contributing to preserve the good with its optimal contribution level, and all the other agents being free-rider...

Desarrollamos un modelo de adopción de lenguaje basado en un modelo evolutivo genera-do por un juego con dos poblaciones y tres estrategias y encontramos dos equilibrios estables, a saber: bilingüismo en ambas poblaciones y monolingüismo basado en la lengua vernácula de cada población.
Article
In this document, we analyse the strategic complementarity between technological investment and investment in training by workers. We show that, beyond the importance of the answer to the question about which factor determines which, initial minimal conditions in both factors are required to start a long-run social development process. If these min...

We develop a simple mathematical model describing the dynamics of the gender gap in a labor market niche and study the effects of bias, market size, and market dynamism in the evolution of the system. A high-level characterization of the system is suggested by studying a large sample of the parameter space, and specific cases of interest to policy-...
Article
In this paper, we consider a general equilibrium model in which the economies are characterized by the distribution of firms on a set of branches of production; we will show that based on the decisions of the managers of the firms, it is possible to build a dynamic system whose solutions reproduce the possible trajectories of the economy. Once the...

Full-text available
In this paper we propose and analyze a game theoretical model regarding the dynamical interaction between government fiscal policy choices toward innovation and training (I&T), firm's innovation, and worker's levels of training and education. We discuss four economic scenarios corresponding to strict pure Nash equilibria: the government and I&T pov...

We introduce an evolutionary dynamical model for corruption in a democratic state describing the interactions between citizens , government and officials, where the voting power of the citizens is the main mechanism to control corruption. Three main scenarios for the evolution of corruption emerge depending on the efficiency of the institutions and...
Chapter
Full-text available
The paper aims to study the co-evolution dynamics of human capital and innovative firms by means of an evolutionary game theory model. We analyze the properties of the model, showing that if the demand for skilled labor is higher than its supply, then innovative firms may have an incentive to become non-innovative and stop hiring skilled workers. I...
Article
Full-text available
In this work, we analyze the possible evolution of an economy in which,up to a certain point, the State acted as a monopolist in the provision of a set of public services and, faced with a change in the economic situation, poses itself, the question about whether these services should continue to be, as they were until then, provided by the State o...
Article
The problem of the consumption or provision of common and public goods is a well known and well studied problem in economic sciences. The nature of the problem is the existence of non-excludable externalities which gives rise to incentives to free-riding behaviour. There are several economical frameworks trying to deal with the problem such as coal...
Article
Full-text available
In this paper, we consider a two-country and two-sector economy, where firms can choose to be innovative or not innovative, and workers to be skilled or unskilled. Using a dynamic game, we argue that exploiting the comparative advantages a country has in producing goods that use the most abundant factor of production, free mobility of capital and l...

El presente trabajo pretende mostrar cómo la geometría diferencial y los sistemas dinámicos permiten entender, explicar y avanzar en el estudio de problemas económicos relevantes. Pretendemos convencer al lector de que una teoría formalmente desarrollada puede no estar muy lejos de la práctica más inmediata y que, por otra parte, los problemas que...
Article
Full-text available
The aim of this article is to give at least a partial answer to the question made in the title. Several works analyze the evolution of the corruption in different societies. Most of such papers show the necessity of several controls displayed by a central authority to deter the expansion of the corruption. However there is not much literature that...

Full-text available
In this paper, it is shown that any migratory flow, imposed by the imitation of the like, can be modeled by a dynamic system, once the rules governing imitative behavior are established. The parameters that characterize this system are determined by the social and economic conditions existing in the countries between which it is established and can...

In this paper we extend the well known result of existence of Walrasian equilibrium given in Debreu (1952) to economies modeled over topological vector spaces. Our work is closely related to the previous results of Yannelis-Pranhakar (1983), and Tan and Yuan (1999), but unlike these papers we prove the existence of a Walrasian equilibrium in infini...

Full-text available
Lower profit rates play an importan role in the evolution of an ownership private economy. We argue that if managers look to maximize profits rates, then the decision to change, to those branches, or technologies, that offer higher rates of profits, plays an important role in the characterization of economies. If managers choose to produce accordin...

Desde principios de la década de los noventa inicia el estado del bienestar sueco un proceso de transformaciones que permite la participación de agentes privados en sectores emblemáticos de la sociedad de bienestar, tales como educación, salud, atención infantil y asistencia a personas adultas. Hasta la fecha, la experiencia muestra que la coexiste...
Article
The object of this paper is to study the labor market using evo- lutionary game theory as a framework. The entities of this competitive model are firms and workers, with and without external regulation. Firms can either innovate or not, while workers can either be skilled or not. Under the most simple model, called normal model, the economy rests i...

Full-text available
It is recognized that corrupt behavior determines the institutional types of an economic system where an institution is ruled out by economic agents (e.g. officials-public or private) abusing their role to procure gain for themselves (rent-seeking activities) or somebody else. In this vein, we study an evolutionary model of institutional corruption...
Article
This paper studies the joint dynamics of corruption and pollution in a model of evolutionary game theory, where firms face a given pollution standard and the government must check the compliance to this standard by means of public officials who can be honest or not. A novelty of our paper is that officials decide to be honest or not by imitation, w...
Article
This paper studies the evolutionary dynamics of migration. We argue that, under bounded rationality, the strategic foundations of the migrant behavior are based in the imitation of peers. We show that any migratory flow can be modeled from a dynamical system, whose parameters reflect the social and economic policies implemented by the decision make...

Full-text available
This paper provides an extended framework to study general equilibrium theory with commodity spaces possibly of infinite dimensions. Our approach overcomes some difficulties found in the literature since it allows the study of the equilibrium when consumption sets may have an empty interior. It also overcomes the need for separable utilities or uti...
Article
The natural projection plays a fundamental role to understand the behavior of the Walrasian economies. In this paper, we extend this method to analyze the behavior of infinite dimensional economies. We introduce the definition of the social equilibrium set, and we show that there exists a bijection between this set and the Walrasian equilibrium set...
Article
A stumbling block in the modelling of competitive markets with commodity and price spaces of infinite dimensions, arises from having positive cones with an empty interior. This issue precludes the use of tools of differential analysis, ranging from the definition of a derivative, to the use of more sophisticated results needed to understand determinac...

Article
We study a coordination game, between a leader population and a follower population. Each individual of each population follows an imitative behavior in order to decide between being a high- or low-type economic agent. We show that individual behavior driven by imitation can lead to an economy that is either in a low-level equilibrium—a poverty tra...

El objetivo de este trabajo es considerar la posibilidad de que, en el largo plazo, un monopolio natural se mantenga como tal debido al resultado del aumento de su productividad ocasionado por el cambio tecnológico. Paralelamente, se discutirá sobre la pertinencia de implementar políticas tendientes a incentivar la competencia y la libre entrada en...
Article
One can restructure institutions, but if individual-level motivations for corrupt behavior are not understood, these restructuring may not be effective. We introduce an evolutionary-game modeling to deal with the problem of corruption driven by imitative behavior.
Chapter
We study an evolutionary game with two asymmetric populations where agents from each population are randomly paired with members of the other population. We present two imitation models. In the first model, dissatisfaction drives imitation. In the second model, agents imitate the successful. In the first model, we use a simple reviewing rule, while...

The Pareto optimal concept does not concern with fairness or equality, it is a concept related to efficiency. In this paper, using techniques from the general equilibrium theory, we relate efficiency, fairness and stability of an economy.
Article
General Equilibrium Theory (GE) scrutinizes the ability of markets to achieve efficient allocation of resources. Our main purpose is, in the framework to the GE to analyze, the possibility of design a mechanism enabling agents to make independent decisions compatible with social welfare. More precisely, we address the problem of the possibility of...

We study an economy with heterogenous workers and firms as a two population game, in normal form, and its evolutionary dynamics implied by strategic complementarities. The population of firms is distributed in two groups, innovative and non innovative, while workers need to choose between two strategies, acquiring skills or remaining unskilled. Wit...
Article
Abstract The economy under study is populated by two types of firms (innovative and not) and two types of workers (skilled and unskilled). The aim is to develop a model that confirms the existence of complementarities between innovative firms (R&D activities) and skilled workers (human capital) and traces corresponding optimal dynamics. Workers fol...

We consider an economy with two types of firms (innovative and non-innovative) and two types of workers (skilled and unskilled), where workers' decisions are driven by imitative behavior, and thus the evolution of such an economy depends on the initial distribution of the firms. We show that there exists a continuous of high level steady states and...
Article
Full-text available
We study an imitation game of strategic complementarities between the percentage of high-skilled workers and innovative firms, namely, human capital and R&D, respectively. We show that this model has two pure Nash equilibria, one of them with high investment in R&D and skilled workers while the other one, which we interpret as poverty trap, exhibit...

In this work we analyze the relation between social welfare, and Pareto optimal allocations. As it is well know, each Pareto optimal allocation has associate a specific vector of social weights (one to each agent of the economy). This vector has associate a specific social utility function (the Negishi function) and then, each Pareto optimal alloca...

We consider an extensive form game to analyze the interdependence between environmental protection of resources, the activities related with the tourism and the behavior of a local population. We answer two questions: 1) Suppose that the central planner invest in tourist activities, has he incentives to do an aggressive propagandistic campaign to c...
Article
In this short paper we analyze the impact of tourist demand in hotel rooms on the investment of hotels on environmental quality. We show that when income of the tourists increases, then to maintain the demand for rooms, the hotels must in-crease the investment on the environmental quality of the region where there is an increment of the tourist act...

This paper studies the impact of a correct valuation of the opportunity costs in individual decisions and social welfare applied to a tourism problem. Starting from a partial equilibrium model, the study shows that the valuation of social welfare depends on the definition of individual opportunity costs. In particular, this study suggests that if t...

This paper introduces a model of economic growth intended for representing developing countries that exhibit poverty traps. The policies of financial restraint that are usually asked for to those countries are shown here to lead to a lower equilibrium. That is, they do not allow those economies to get out of their poverty traps. Sustained investmen...

In standard economic growth theory it is assumed that labor force follows exponential growth, a not realistic assumption. As described in Maynard Smith (1974), the growth of natural populations is more accurately depicted by a logistic growth law. In this paper we analyze how the Ramsey growth model is affected by logistic growth of population, com...

One of the key elements in economic growth theory is that population grows exponentially. In this paper we reformulate the Ramsey model of economic growth by assuming that the law describing population growth verifies two stylized facts: 1) population is strictly increasing and bounded and 2) the rate of growth of population is strictly decreasing...

Usually standard economic growth theory assumes that population grows exponentially. This hypothesis is realistic only for an initial period, but it can not be valid indefinitely because, population growing exponentially can be arbitrarily large. In this paper we reformulate the Ramsey model of optimal economic growth by substituting the exponentia...
