Game Theoretic Model

Although there were 152 million mobile phones in Brazil as of January 2009, a research conducted by the International Communications Union in 2008 revealed that amongst the 154 countries surveyed, Brazilian users paid the most for the use of mobile phones. Between 2008 and 2009, Anatel introduced mobile number portability as a measure that would promote greater competition amongst operators. This article sought to evaluate the impacts of this policy on competition in the Brazilian mobile telephony segment, particularly as to fees charged. To this effect, both a static and a dynamic analytical framework were built, based on the Prisoners‟ Dilemma Game-Theoretic Model. Theoretical propositions were compared to empirical data related to the mobile fees charged in São Paulo and indicated that the implementation of the mobile number portability policy did not bring about the reduction of fees charged to consumers. This finding contradicts the price reduction phenomenon that occurred in other countries after implementing the portability policy and suggests the need for further rulings which pose to encourage carriers to charge lower fees.

The Right

Adjustable-Rate Bonds with Puts (ARBP), frequently issued by the Russian companies, give the issuer the right to arbitrarily change the coupon payments on the bonds at certain moments. But at these moments, the investor has the right to force the issuer to redeem the bonds at a face value. These reciprocal actions of the issuer and investors can be considered as a dynamic game. We suggest a game-theoretic model that allow to determine the optimal decisions of the players. These decisions are compared with empirical data.

Informal Value Transfer System

Informal financial operations exist in the shadow of official regulation and cannot be protected by the formal legal instruments, therefore raising concerns about the enforcement of obligations taken by their participants. This paper analyzes two alternative types of auxiliary institutions, which can coordinate expectations of the members of informal value transfer systems, namely attitudes of trust and norms of social control. It offers some preliminary approaches to creating a game-theoretic model of partner interaction in the informal value transfer system. It also sheds light on the perspectives of further studies in this area of institutional economics.

The Impact

Strong labour laws play a major role in motivating innovation among employees. It has been found in the literature that stringency of labour laws is positively linked with employees’ efforts in innovation, in particular, wrongful discharge laws (WDL). However, employees may also bring nuisance suits against employers. Usually, the result of these suits is that both parties settle with each other. Thus, even if employees are justly dismissed, they may be able to bring nuisance suits against employers and gain a settlement amount. This article investigates how the possibility of nuisance suits affects the impact of WDL on employees’ efforts in innovation. In this respect, a game-theoretic model is developed in the article to find the equilibrium level of employees’ efforts in the presence of nuisance suits, where there is a possibility of employees getting discharged from the firm. I find that if nuisance suits are a possibility, the stringency of WDL has no impact on employees’ efforts if defence cost of the firm is low; but for higher defence costs, WDL affects employees’ efforts. The efforts exerted by an employee are found to be weakly increasing in the defence costs of the firm.
