Objective: New technology-based firms (NTBFs) are key actors in creating value through innovation, but they face significant challenges in the rapidly changing and competitive technological environment. Methods: This research is a multi-method analysis aiming to present a model of relationships among drivers for collaboration and competition among technology-based companies and identify effective actions and policies to enhance coopetition (cooperation and competition) that can boost the ability of NTBFs to grow and commercialize innovations. The methodology of this study is exploratory in nature. Thus, it employs literature review method for gathering qualitative data, Fuzzy Delphi method for collecting data from experts, and DEMATEL-ISM method for modeling the relationships among drivers and demonstrating the impact of coopetition on the performance of NTBFs. Results: The research findings show that coopetition can improve growth, innovation, and commercialization in NTBFs by overcoming technological and competitive limitations. Conclusions: The study offers practical and social implications for managers, policy makers, and econom

This study aimed to analyze the main determinants of individual income inequality in Brazil. For this, an earnings equation was estimated. We used a twostage approach in order to control both for sample selection bias and endogeneity problems. After that, we used decompositions based on the Shapley value, a solution concept for cooperative games. The results show that education emerges as a most significant determinant of income inequality, no matter what inequality index was take. [ABSTRACT FROM AUTHOR]

A consolidated research line in Brazil identified the proxies for determining the tax aggressiveness of companies listed on the B3 stock exchange. However, none of these studies identified the instrument used by Brazilian companies to carry out tax aggressiveness. Thus, our research seeks to fill this gap by demonstrating that fiscal aggressiveness results from the Brazilian tax complexity, that providing prerogatives to avoid or delay tax payments. Besides, this study is the first accounting study to demonstrate that special installments reduce the actual value of taxes owed by taxpayers, encouraging them to be tax aggressive. Through the foundations of Game Theory, this research demonstrates the cost-benefit of tax aggressiveness in maximizing the profit of tax avoidance. We examined the best strategic decisions in the tax avoidance game concerning the tax complexity and special installments experienced in Brazil. In this game, the only NASH equilibrium is tax avoidance since it is the only option with a chance of remuneration. Therefore, this research contributes to understanding business behavior concerning the Brazilian tax system and provides subsidies to encourage reform of the current tax complexity.

In recent years, restrictions on activities to contain the new coronavirus SARS-CoV-2 encouraged the search for virtual means of entertainment, increasing developments in the sector. Based on the above, this article conducts a research on the way in which natural phenomena are simulated computationally, covering, in this process, concepts of Console Engineering, Digital Game Theory and Gamification, which were analyzed and correlated with what can be observed in the main content of each generation of home video game consoles, proposing to parameterize the notable evolutionary milestones in the frameworks and engines available in each generation. To reach the intended objective, the practice of bibliographic and video phonogram surveys was adopted along with empirical tests performed in the most relevant media of each of the periods explored. Thus, the research was able to demonstrate the levels of Physics simulation immanent in electronic games from different times, also listing some technologies that have potential to be implemented successively.

The theme of this research is mediation and conciliation in the company's judicial reorganization in light of game theory. The analysis will be based on the concept and evolution of the mediation and conciliation institutes. Next, the effectiveness of self-composition will be examined. From this point on, the research goes to an approach to the agreement and mediation in the company's judicial reorganization. In this context, some notions related to the company and its economic and social functions will be highlighted. The objective is, therefore, to carry out an analysis of the self-composition in the judicial reorganization, especially given the complexity of this type of process, which involves a huge number of creditors, often with antagonistic interests. The research technique used is bibliographic and documental, from a deductive approach to the subject. [ABSTRACT FROM AUTHOR]

ABSTRACT The growing number of users, about 250 million, in 2016, and the sheer number of health problems, that cause 190,000 deaths per year, are just some of the data that has rekindled the debate and discussion into the efficiency of the prohibitionist drug policies concerning drug consumption throughout the world. As a result, there has been the establishment of a special branch of literature focused on the investigation into this theme. In this regard, the present article conducts an economic analysis of scenarios where there is no decriminalization of drugs and other areas where legalization has been partial (marijuana) or complete, based on Game Theory. Thus, different from other studies, this paper establishes conditions of compatibility of incentives so that the economy could become formal, after decriminalization, to avoid contraband under a legal guise. This paper also manages to show which situation (Nash equilibrium) provides the greatest well-being for society.

Public participation in art performances has been leveraged by the use of technology as a mediating element between the public and artists. However, technological mediation alone may not be enough to ensure effective auditory participation. In this article, we present the performance “ O Chaos das 5 ”, an audiovisual digital performance with a strong technological support that had the support of game theory to achieve a more effective participation of the audience in their presentations.

Abstract In this paper we present a concept of similarity in games, on which to ground alternative solution concepts, some of which differ from the classical notions in the field. In order to do this we impose a constraint on players’ beliefs that amounts to a variant of the well-known symmetry principle in classical bargaining theory. We show how this similarity relation helps to identify different Nash equilibria in games, and how these “similar Nash equilibria” can be extended to non-symmetric games. While the notion is normative, it is nonetheless inspired by phenomena in which similarities between players lead to outcomes detected in behavioral studies. We study the strategic properties of the concept of similarity and discuss its relationships with Hofstadter’ notion of superrationality.

ABSTRACT This paper highlights the fact that neoclassical theory cannot explain the process of economic change. In an uncertain and ever-changing world, a theory based on static equilibrium models is of little help. Whereas we have placed the institutions at the centre of the understanding of economic systems, since they constitute their incentive structure. Thus, economic change is largely an intentional process created by individuals’ perceptions of the consequences of their actions. These perceptions, coming from the beliefs of individuals, combine with their preferences. In the end, a dynamic theory of economic change will not be built, but an attempt will be made to understand the link between institutions and economic growth, the process of change, and to develop assumptions, within its limits, capable of improving the human environment and economic results.

Abstract: Nash equilibrium is an important concept for studying human behavior in group decision making process. Given the complexity of finding Nash equilibria, computational tools are necessary to find them. Several programs were developed for this task. However, available programs are either not comprehensive or might be of difficult installation and handling, creating a “barrier of entry” to non-specialists. The aims of this research are twofold: (i) firstly, it was to identify and to discuss about the available programs for finding Nash equilibria; and (ii) secondly, based on the theoretical proprieties of a Nash equilibrium, to develop a program capable of finding all pure Nash equilibria in games with “n” players and “m” strategies (“n” and “m” being finite numbers) as a Macro tool for Microsoft Excel®. It is expected that the program can contributed to the area of Operations Research by providing a new tool that facilitate the use of game theory concepts within group decision-making problem-solving scenarios enabling practical applications using a widespread software.

Purpose – To determine the optimal investment strategy in Nash equilibrium for the residential real estate market of Rio de Janeiro, considering the uncertainty in the demand for real estate and the number of active competitors in the market. Design/methodology/approach – A Real Options Game model was developed. The parameters of the model were estimated with econometric tools using data from the Rio de Janeiro real estate market. Findings – The quantitative results obtained are intuitive in the sense that the larger the number of competitors, the lower the level of demand required for investment in new units, whereas the greater the volatility of demand, the greater the demand threshold for the investment to be optimal. Originality/value – This study modified the methodology of Grenadier (2002), providing a more adequate and robust specification of the uncertainty for the demand function, thus allowing more intuitive economic interpretations.

The game theory applied to the context of cooperation between different university researchers, based on an interdisciplinary action, represents a win-win strategy, which combines the need to compete, and also to cooperate. This combination results in a change of episteme regarding our way of conceiving inter-organizational and intra-organizational relationships.

In this paper, we develop a new numerical method, game theory and option pricing to compute a bankruptcy triggering asset value. we will draw our attention to determining a the numerical asset value, or price of a share, at which a bankruptcy is triggered. This paper develops and analyze a cubic spline collocation method for approximating solutions of the problem. This method converges quadratically. In addition, this article also provides with a real-life case study of the investment bank, and the optimal bankruptcy strategy in this particular case. As we will observe, the bankruptcy trigger computed in this example could have served as a good guide for predicting fall of this investment bank.

We present an overview of the field of conflict economics. We begin by explaining important distinctions between standard textbook economics and conflict economics regarding assumptions, subject matter, and interrelations between economics and conflict. We then provide summaries of selected economic theories and empirical evidence that together help reveal important aspects of conflict – and peace – through an economics lens. Among the topics covered in the theoretical and empirical overview are why violence is sometimes chosen over peaceful approaches to address intergroup disputes, why it is “rational” for political leaders to sometimes mass kill civilians (and what can be done to prevent this), how social norms of committing harm against outgroups can propagate (or be stopped), why it can be difficult to develop laws and institutions to promote stable peace, and how third-party efforts to promote peace can sometimes make things worse. Lastly, we provide samples of data resources, working paper archives and journals, and readings consisting of major textbooks, handbooks, and edited books in the field of conflict economics.

This article aims to explain the negotiation techniques used in mediation and the resulting benefits, in particular, the Harvard method and game theory. The problem of work lies in properly understanding conflict as a transformative social fact that, when worked well, strengthens the relationship between the parties. For this, the logicaldeductive methodology was used combined with the study of doctrine and legislation. As a result, it was found that the adoption of a cooperative stance in the litigation enables the multiplication of individual gains and, with that, the achievement of collective gains. As the main contribution of the work, it has been that, when allied with the negotiation techniques of the Harvard method and the theory of Nash games, the use of self-compositional procedures is extremely efficient for the solution of disputes, notably, by providing multiple gains.

This research deals about the use of gamification in a Sociology class. A game where the students, separated into two groups, raffled phrases, in order to try the habitus concept from Pierre Bourdieu, that way they noticed differences between people in the same society, due to non-elective conditions. In game one of those groups always raffled positives features to the future, but the other group, only received situations, experiences or features that hindered or limited the access to cultures or leisure places, usually related to a specific social context. The goal was that with playful stimulus, and a visual representation, the habitus explanation have a better understanding by the students. Differently the usual class, first the game was played and in the end happened the theoretical explanation, this way, while the game the students make some commentaries, using their minds to build knowledge and not just passively received it. Engagement in debates was noted, and they created theories trying to explain the distances between the groups, initially lined up, this causes a visual and emotional impact, felt in different ways by the members which group. They learned about Hegelian dialectic too, making theories were refuted by friends, and building a new theory to explain the game. [ABSTRACT FROM AUTHOR]

One field of the most fertile in the study of the strategies is the Theory of Games, which aims to capture the behavior of individuals in strategic situations. This paper aims to analyze the evolution of strategies of suppliers and borrowers credit by proposing two simultaneous and reflective games, making, for both, computational simulations. Two games were held simultaneously, where the results of an influence the pay-offs of each other. After 400 generations, it's believed that this is due to the complex interaction between the two groups of actors and is not seen as a setback by the authors of the study, whereas data on the evolution of strategies is fertile ground for valuable analysis on the interaction of actors in this study. The conclusions show the potential of techniques for analyzing and understanding the strategic behavior of SMCs in their relationship with suppliers of large companies. [ABSTRACT FROM AUTHOR]

This paper presents an analysis of the effects of bargaining in agricultural markets, specifically the cattle market, based on a theoretical and empirical analysis method. Using primary and secondary data, and theories of cooperative games, through Nash's solution and Rubinstein's theorem, in order to evidence the inequality that can occur in negotiations at agricultural fairs. The results show an inequality between the possible prices between buyer and seller, as also the work diagnosed, through the theories, that for matching the corresponding price with a situation of equality in the bargaining power, it would be necessary a virtual easing of the point of disagreement of the buyer, so in comparison with the model of the Nash solution there would be a difference in bargaining power unfavorable to the seller. The results also show a difference in the seller's patience soon confirming also the existence of disadvantage for the seller during the commercializations by the model of Rubinstein.

This paper provides a new way of analysing the concept of change within the field of military history. The proposal is based on the use of complex adaptive systems and evolutionary theory. We introduce the concepts of selection, adaptation and coevolution to explain how war is managed in different societies, and game theory to explore decision-making processes of commanders. We emphasize the value of integrating formal modeling and computational simulations in order to apply the approach to real case studies. Our conclusions outline the advantages of an evolutionary military history in the difficult task of understanding the causes of transformation in past battlefields and armies.

The 2007 USA financial crisis impacted in the European Union (EU) countries. The EU states suffered in 2009 the greatest fall in their economic activities since the II World War. Some EU countries with higher previous economics imbalances, like Greece, suffered the distrust of financial markets and had to implement austerity policies. Greece was one of the first EU countries to show financial crisis signs due to increase its sovereign risk. In the present work we analyzed, from the principles of game theory, how different financial agents (Greek Government, Investors and the EU), made decisions that led into Greece crisis. The financial agents decisions are shown as a dynamic game with complete information. This paper also provides the solution of the game through Nash equilibrium.

A psicologia evolucionista propõe uma investigação sobre as origens e os propósitos das habilidades cognitivas que constituem a cognição social humana. Este artigo procura apresentar a teoria do contrato social como um modelo evolucionista para o estudo de mecanismos cognitivos associados às trocas sociais e da cooperação, tais como: detecção de trapaça, memória de faces, senso de justiça, influência da informação e conhecimento prévio, vigilância e teoria da mente que regulam, fundamentalmente, nossas interações sociais. Conclui-se que um olhar evolucionista para a mente humana gera hipóteses, enquanto a teoria dos jogos fornece métodos para testá-las, nos auxiliando a compreender a natureza humana.Evolutionary psychology proposes the investigation of the origins and purposes of cognitive skills that constitute human social cognition. This article presents the social contract theory as an evolutionary model for the study of the cognitive mechanisms and cooperation, such as cheating detection, memory for faces, sense of justice, the influence of prior knowledge and information, vigilance and theory of mind that regulate social interactions. It is concluded that an evolutionary view of human mind produces hypotheses, while game theory provides methods to test them, helping us to understand human nature.
