Strategic formation of homogeneous bargaining networks

Gauer F. Strategic formation of homogeneous bargaining networks. Center for Mathematical Economics Working Papers. Vol 529. Bielefeld: Center for Mathematical Economics; 2014.We analyze a model of strategic network formation prior to a Manea (2011) bargaining game: ex-ante homogeneous players form an undirected network with explicit linking costs anticipating expected equilibrium payoffs from the subsequent sequential network bargaining. Assuming patient players, we provide a complete characterization of networks being pairwise (Nash) stable on a cost interval of positive length: specific disjoint unions of separated pairs, odd circles and isolated players constitute this class. Even for all single cost levels we are able to exclude a wide range of structures from being pairwise stable, including all other equitable networks. As an important implication, this reveals the diversity of possible bargaining outcomes to be substantially narrowed down provided pairwise stability. Further, we find that for sufficiently high costs the pairwise stable and efficient networks coincide whereas this does not hold if costs are low or at an intermediate level. As a robustness check, we also study the case of time-discounting players

Dynamic Multilateral Markets

We study dynamic multilateral markets, in which players’ payoffs result from coalitional bargaining. In this setting, we establish payoff uniqueness of the stationary equilibria when players exhibit some degree of impatience. We focus on market games with different player types, and derive under mild conditions an explicit formula for each type’s equilibrium payoff as market frictions vanish. The limit payoff of a type depends in an intuitive way on the supply and the demand for this type in the market, adjusted by the type-specific bargaining power. Our framework may be viewed as an alternative to the Walrasian price-setting mechanism. When we apply this methodology to the analysis of labor markets, we can determine endogenously the equilibrium firm size and remuneration scheme. We find that each worker type in a stationary market equilibrium is rewarded her marginal product, i.e. we obtain a strategic underpinning of the neoclassical wage. Interestingly, we can also replicate some standardized facts from the search-theoretical literature such as positive equilibrium unemployment.Multilateral Bargaining, Dynamic Markets, Labor Markets

Learning difficulties: collaborative inter-organisational information system use within UK retail supply networks

Inter-organisational information systems (IOIS) have been introduced to support collaborative retail supply relationships, yet how these systems are used is not well understood. This paper presents analysis of an ideographic case study of a dynamic United Kingdom grocery sector supply network. Using Archer's (1995) social change theory we explore how changes to buyer-supplier relationship structures re-conditioned individual actors' situational logics in a way that created network learning difficulties. Our analysis shows how actors' inter-organisational information system use reinforced pre-existing bargaining positions and improved already powerful actors' relative negotiating strength. This paper demonstrates the value of multi-level analysis in furthering understanding of the complex relationships between processes of network and individual learning

Bargaining Coalitions in the Agricultural Negotiations of the Doha Round: Similarity of Interests or Strategic Choices? An Empirical Assessment

The paper aims at understanding the structural features of the bargaining coalitions in the Doha Round of the WTO. We provide an empirical assessment of the preferences of each negotiating actor looking at general economics indicators, development levels, structure of the agricultural sectors, and trade policies for agricultural products. Bargaining coalitions are analyzed by grouping countries through a cluster analysis procedure. The clusters are compared with existing coalitions, in order to assess their degree of internal homogeneity as well as their common interests. Such a comparison allows the detection of possible “defectors”, i.e. countries that according to their economic conditions and policies seem to be relatively less committed to the positions of the coalition they join.Agricultural trade negotiations, Bargaining coalitions, WTO, Cluster analysis

Product market integration and endogenous bargaining structure

This paper focuses on the effects of product market integration on wage-bargaining institutions in a one-way trade model of an international Cournot oligopoly. It shows that product market integration (i.e. a reduction in trade costs either from an arbitrary or from its optimal level) lowers the incentives to centralisation for home unions, given that firms always prefer decentralisation, making it more likely that a decentralised wage bargaining structure occurs in equilibrium.Bargaining institutions, unionised oligopolies, trade integration

The Puzzle of Social Preferences

We present a brief overview of the experimental economics literature on social preferences. In numerous experiments, economically incentivized subjects are willing to sacrifice part of their material earnings to compensate the kind behavior of others, or will be willing to reciprocate at a non-negligible cost, or even pay a positive price for punishing the behavior of selfish individuals. All these actions are labeled as social in economics because there is no apparent way to reconcile them with any reasonable form of pure self-interest. We focus on social dilemma games and want to communicate two main messages. First, research in experimental economics has produced abundant evidence that illustrates the social components of people’s preferences. Second, social sanctions of different types play an important role in facilitating cooperative behavior.

Diffusion of shared goods in consumer coalitions. An agent-based model

This paper focuses on the process of coalition formation conditioning the common decision to adopt a shared good, which cannot be afforded by an average single consumer and whose use cannot be exhausted by any single consumer. An agent based model is developed to study the interplay between these two processes: coalition formation and diffusion of shared goods. Coalition formation is modelled in an evolutionary game theoretic setting, while adoption uses elements from both the Bass and the threshold models. Coalitions formation sets the conditions for adoption, while diffusion influences the consequent formation of coalitions. Results show that both coalitions and diffusion are subject to network effects and have an impact on the information flow though the population of consumers. Large coalitions are preferred over small ones since individual cost is lower, although it increases if higher quantities are purchased collectively. The paper concludes by connecting the model conceptualisation to the on-going discussion of diffusion of sustainable goods, discussing related policy implications

A theoretical analysis of the relationship between social capital and corporate social responsibility: concepts and definitions

The paper studies the relationship between social capital (SC) and Corporate Social Responsibility (CSR) by investigating the idea of a virtuous circle, between the level of SC and the implementation of CSR practices, that fosters socio-economic development by generating social inclusion and social networks based on trust and trustworthiness. Following the literature on SC that stresses its multidimensional character, both a cognitive and a structural idea of SC are considered. The first one essentially refers to the dispositional characters of agents that affect their propensity to behave in different ways. The latter refers to social networks connecting agents. With regard to the concept of CSR, a contractarian approach is adopted and CSR is considered as an extended model of corporate governance, based on the fiduciary duties owed to all the firm’s stakeholders. Among stakeholders, a original distinction between “strong” and “weak” stakeholders is introduced. The key element that allows to distinguish between strong and weak stakeholders concerns the consequences that the break in the relationship with the firm produces both on the stakeholder and on the firm. Both these two categories have made specific investments in the firm. However, strong stakeholders are precious for the firm because they bring in strategic assets. On the contrary, weak stakeholders do not bring strategic assets into the firm and firms have material incentives at defecting in the relationship with them. Considering the notions of cognitive and structural SC, a contractarian approach to CSR and the distinction between weak and strong stakeholders, the paper shows that: a) the level of cognitive SC plays a key role in inducing the firm to adopt and observe CSR practices that respect all the stakeholders; b) the decision of adopting formal instruments of CSR contributes to create cognitive SC that is endogenously determined in the model; c) the level of cognitive SC and the decision of adopting CSR practices creates structural SC in terms of a long term relationship between the firm and the weak and strong stakeholders.Social capital, Corporate Social Responsibility, Social network, Ideal utility, Cooperation, Trust.
