Separating Equilibrium

Advertising in a social network has a number of characteristics that distinguish it from other types of advertising, and which may be of key importance in answering the question about its ability to serve as a signal of quality. In the game-theoretic model presented in this paper, the monopolist sends an advertising signal to bloggers who act as “opinion leaders” in the social network. The latter, in turn, make decisions about posting advertising messages on their blogs, taking into account the impact that this action may have on their reputation. The paper investigates the question of when advertising can serve as a reliable signal of quality in a separating equilibrium.

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.

Ideological Difference

We build a two-stage game theoretic model to capture the effect of ideologies of parties in a coalition on disinvestment decisions. We focus on three specific aspects of ideology—ideology score of the coalition, ideology dispersion of the coalition, and ideology difference between the center and the state where the enterprise is located. The benchmark two-party coalition predicts that a left government prefers less disinvestment than a right one more often than not. However, there may be a case where moving toward the left end of the ideology spectrum may raise disinvestment incidence. Similarly, a coalition with ideologically similar parties favors privatization more frequently than one in which parties are more diverse. However, for a narrow parametric range, the effect may be reversed. Low ideological difference between the center and the state in which the enterprise is located improves disinvestment incidence. Finally, we extend the model to three-party coalitions.

Abstract In this article, I directly test the hypothesis that interactions between inventors of different firms drive knowledge spillovers. I construct a network of publicly traded companies in which each link is a function of the relative proportion of two firms’ inventors who have former patent collaborators in both organizations. I use this measure to weigh the impact of R&D performed by each firm on the productivity and innovation outcomes of its network linkages. An empirical concern is that the resulting estimates may reflect unobserved, simultaneous determinants of firm performance, network connections, and external R&D. I address this problem with an innovative IV strategy, motivated by a game-theoretic model of firm interaction. I instrument the R&D of one firm’s connections with that of other firms that are sufficiently distant in network space. With the resulting spillover estimates, I calculate that among firms connected to the network the marginal social return of R&D amounts to approximately 112% of the marginal private return.

AbstractThis paper uses a game-theoretic model to examine the role of reference price for firms that vary in their quality positioning in competing for customers. Reference prices provide consumers with additional components of utility. Building on previous research on the impact of consumer decision making on firm strategies, we focus on how firms choose their positioning when consumer utility is driven not only by acquisition utility but also by the transaction utility associated with the purchase and how this, in turn, affects firms’ pricing decisions and profits. Considering a competition between two firms, this paper shows that the firm with higher product quality provides greater discounts to consumers. We also show that when firms are allowed to set a high ‘regular’ price, product differentiation is greater between the firms, and price competition is less intense. Furthermore, under some conditions, the profits of both firms can be higher than the benchmark case (when the effects of transaction utility are ignored).

Patent Validity

We study the welfare economics of probabilistic patents that are licensed without a full determination of validity. We examine the social value of instead determining patent validity before licensing to downstream technology users, in terms of deadweight loss (ex post) and innovation incentives (ex ante). We relate the value of such pre-licensing review to the patent's strength, i.e., the probability it would hold up in court, and to the per-unit royalty at which it would be licensed. We then apply these results using a game-theoretic model of licensing to downstream oligopolists, in which we show that determining patent validity prior to licensing is socially beneficial.

The Impact

In behavioral ecology, the behavioral consequences of individuals (exploiters) using the investments of others (investors), rather than investing time or effort in procuring a resource themselves, has been traditionally studied using the producer–scrounger (PS) model—a simple evolutionary game theoretic model in which producers (investors) search for resources while scroungers (exploiters) use the resources found by producers. A key assumption in the PS model is that the producer remains passive toward scroungers. As the presence of scroungers is costly, evidence is reviewed that one major consequence of having exploiters is the adoption by producers of strategies that reduce the benefits of scroungers, giving rise to countermeasures by scroungers. Scroungers also affect population structure by generating consistent differences among individuals and affecting spatial preferences within groups. Reviewing the impact of scrounging on populations should help generate parallels to explore the consequences of exploitative behavior in economics and public health.

Abstract Given consumers’ trade-offs between conventional economic and environmental attributes of products, we provide a game-theoretic model to explore the role of GTA strategy in duopoly competition by incorporating two salient features: Two product types — The green product produced by a firm with GTA strategy and the ordinary product produced by a firm without GTA strategy, and two consumer segments, i.e., the green consumers who are willing to pay for green products and the ordinary consumers who are willing to pay for ordinary products. Our analysis shows that GTA strategy may either increase or decrease the green firm’s quality provision. The subtle relationship between the green firm’s quality strategy and GTA strategy not only affects its own equilibrium performances but its rival’s. We also find that two consumer segments may be better off in the presence of a lower GTA intensity. Additionally, although the GTA strategy benefits the environment, the GTA investment is not the more the better. Finally, we find that GTA strategy would lead to higher social welfare only when the GTA efficiency is high enough. Our work not only provides an alternative economic explanation why some firms choose to implement GTA strategy and some do not in reality, but gives managerial insights for firms with different GTA strategies as well as policy insights for the social planner.

The problem of developing tools for the stimulation system of socially optimal actions (volunteering) is considered. Based on the study of the population’s differentiation according to the propensity to an altruism, the game-theoretic model of the social group’s behavior is formed, accounting for the incentives for volunteering. In the cases of the linear decreasing incentive function and the linear cost functions of agents, the Cournot-Nash equilibrium mechanism in the corresponding game is proved. An existence of the equilibrium actions and an impact of incentives on the volunteers’ time distribution are confirmed by the simulation of the volunteers’ behavior in Russia.

Settlers flocking to boomtowns on the American western frontier were faced with the same task that communities in weak states across the globe face in contemporary times: self-governance. Peer sanctions can enforce cooperation in these environments, but their efficacy depends on the social networks that transmit information from peer to peer. The author uses a game-theoretic model to show that peripheral network positions can generate such strong incentives to misbehave that persistent cheating occurs in equilibrium. The model reveals that groups maintaining high levels of cooperation that face shocks to their strategic environment or to their network can ratchet down into less cooperative equilibria in which the most peripheral become ostracized. Furthermore, population change that features rapid growth, high turnover, and enclave settlements can undermine cooperation. The insights from this article help to explain the trajectory of cooperation in the mining towns of the Wild West in which high levels of cooperation deteriorated as the population surged, and help to make sense of why only certain nonwhite settlers were targets of hostility and racism.
