A Model of the Origins of Basic Property Rights

This paper studies the origins of one of the most basic of property rights, namely, the right of an individual or an organization to the fruits of its labour. My objective is to address the questions of why, when and how this property right can emerge and be made secure. I develop a model of the strategic interaction between two players in the state-of-nature, which is an environment characterized by the absence of any laws and institutions (including property rights and the state). My analyses explores, in particular, the roles of the players� fighting and productive skills on the emergence and security (or otherwise) of this property right.

Spatial Pillage Game

A pillage game is a coalitional game as a model of Hobbesian anarchy. The spatial pillage game introduces a spatial feature into the pillage game. Players are located in regions and can travel from one region to another. The players can form a coalition and combine their power only within their destination regions, which limits the exertion of the power of each coalition. Under this spatial restriction, a coalition can pillage less powerful coalitions without any cost. The feasibility of pillages between coalitions determines the dominance relation that defines stable states in which powers among the players are endogenously balanced. With the spatial restriction, the set of stable states changes. However, if the players have forecasting ability, then the set of stable states does not change with the spatial restriction. Core, stable set, and farsighted core are adopted as alternative solution concepts.allocation by force, coalitional games, pillage game, spatial restriction, stable set, farsighted core

The Role of Inter-Group Relationships in Institutional Analysis

Taking value as the socio-economic analogue of biological or cultural fitness, in this paper I start a study of the interaction between individual-level and group-level explanatory mechanisms by looking for what kind of intra-group relationships obtains given the nature of inter-group relationships. Specifically, it is shown that when value comes from appropriating resources from other groups, inter-group relationships are conflictual or war-like and, as a consequence, intra-group-relationships are centralized and hierarchical; when the value creation process involves niche-competition between groups, inter-group relationships are fission-fusion with commitment and intra-group relationships are decentralized and egalitarian; finally, when value comes from appropriating occasional benefits from cooperation, inter-group relationships are indistinguishable from intra-group relationships, and the latter are decentralized and hierarchical. Interpreting intra-group relationships as different forms of social order and the division of labour, applications to political and economic institutions are also provided. Exploitation, a well-defined concept in the paper without recourse to the labour theory of value, is shown to be consistent with some of these institutions and, particularly, with the absence of explicit coercionvalue, distribution, exploitation

Make Him an Offer He Can’t Refuse: Avoiding Conflicts through Side Payments

The equilibrium of a two-stage conflict game with side-payments predicts that with binding stage-one offers, proposers make and responders accept side-payments, generating settlements that strongly favor proposers. When side-payments are non-binding, proposers offer nothing and conflicts always arise. Laboratory experiments confirm that binding side-payments reduce conflicts. However, 30% of responders reject binding offers, and offers are more egalitarian than predicted. Surprisingly, non-binding side-payments also improve efficiency, although less than binding. With binding side-payments, 98% of efficiency gains come from avoided conflicts. However, with non-binding side-payments, only 49% of gains come from avoided conflicts and 51% from reduced conflict expenditures.contest, conflict resolution, side payments, experiments

"Who's the thief?": Asymmetric Information and the Creation of Property Rights

This paper studies the creation of property rights in a state of anarchy and in the presence of uncertainty about a potential appropriator's ability. In a game of conflict, securing property can be achieved by spending resources for protection. We show that secure property rights will never emerge in equilibrium. The reason for this finding is not that it is not possible to secure property in principle, but that because of uncertainty agents will choose to protect their possessions against an expected appropriator and not against the most able one. Hence, agents voluntarily expose themselves to the risk of losing ownership. This finding has important consequences, since secure property rights are a fundamental prerequisite of economic activity, and insecure property may for example hinder the exploitation of mutually beneficial trade opportunities or distort investment and production incentives.Asymmetric Information, Property Rights, Conflict

A Tale of Markets and Jungles in a Simple Model of Growth

Institutions determine prospects for economic growth and development. This paper collapses potentially complex interactions of different institutions into a simple condition on the primitives that determines whether a society supports spot markets or not. In a dynamic model of an agrarian economy agents are heterogeneous in land holdings, skill, and food endowments. Food holdings serve as a proxy for agents' power to expropriate. The main point of interest is whether land is assigned to the skilled or to the powerful, i.e.\ by coalitional expropriation or by markets. The model finds two different types of limit behavior: a sequence of stable markets and a limit cycle where markets and expropriation alternate. More equal first period endowment distributions facilitate sustainable markets that, in turn, enhance economic efficiency and decrease macroeconomic fluctuations.Expropriation, inequality, institutions, growth, volatility

Side-Payments and the Costs of Conflict.

Conflict and competition often impose costs on both winners and losers, and conflicting parties may prefer to resolve the dispute before it occurs. The equilibrium of a conflict game with side-payments predicts that with binding offers, proposers make and responders accept side-payments, generating settlements that strongly favor proposers. When side-payments are non-binding, proposers offer nothing and conflicts always arise. Laboratory experiments confirm that binding side-payments reduce conflicts. However, 30% of responders reject binding offers, and offers are more egalitarian than predicted. Surprisingly, non-binding side-payments also improve efficiency, although less than binding. With binding side-payments, 87% of efficiency gains come from avoided conflicts. However, with non-binding side-payments, only 39% of gains come from avoided conflicts and 61% from reduced conflict expenditures.contests, conflict resolution, side-payments, experiments

Inter and intra-group conflicts as a foundation for contest success functions

This paper introduces a notion of partitioned correlated equilibrium that extends Aumann's correlated equilibrium concept (1974, 1987). This concept captures the non-cooperative interactions arising simultaneously within and between groups. We build on this notion in order to provide a foundation for contest success functions (CSFs) in a game wherein contests arise endogenously. Our solution concept and analysis are general enough to give a foundation for any model of contest using standard equilibrium concepts like e.g., Nash, Bayesian-Nash or Perfect-Nash equilibria. In our environment, popular CSFs can be interpreted as a list of equilibrium conjectures held by players whenever they contemplate deviating from the ``peaceful outcome'' of the ``group formation game''. Our setup allows to relate the form of prominent CSFs with some textbook examples of quasi-linear utility functions, social utility functions in the spirit of Fehr and Schmidt (1999) and non-expected models of utility a la Quiggin (1981, 1982). We also show that our framework can accommodate situations in which agents cannot correlate their actions.Contest success functions; Correlated equilibrium; Inter and intra-group conflicts; Induced contests
