International Organizations as Corporate Actors: Agency and Emergence in Theories of International Relations

In this paper, the implicit and explicit conceptualizations of international organizations found in the three major theories of international relations are outlined and compared. It turns out that in a neorealist framework, international organizations can be explained; however, they exhibit no autonomy and cannot therefore be conceptualized as a corporate actor. Principally, the same applies to rational choice institutionalism, although limited autonomy is conceivable. Both theories are reductionist in the sense that they do not allow a corporate actor beyond the nation-state. International organizations are at best instruments of state interests. Solely social constructivist theories allow a conceptualization of international organizations as partly autonomous corporate actors. The reason for this conceptual openness lies in its ontology that includes ideational factors such as knowledge and ideas. The concept of emergence gives the core explanation for international organization autonomy: identities and interests of states and international organizations constitute each other mutually. This is specified by referring to the generation of new knowledge within international organizations as the key feature which accounts for feedbacks to the member-states of international organizations. This power of international organizations to alter perceptions and identities of their own ‘founding fathers’ makes them more than state instruments. International organizations thereby gain autonomy, which justifies conceiving of them as high-order corporate actors in international relations.

The Role of Choice in Social Dilemma Experiments

On the basis of problems related to asymmetric information, self-governance has been proposed and often empirically found to be superior to the external imposition of rules in social dilemma situations. The present paper suggests and experimentally analyses a different line of argument, namely to what extent behavioral aspects can explain these findings. We study this hypothesis using the simplest, most general dilemma form: the prisoner's dilemma (PD). We compare behavior when players are given the possibility of choosing between two different representations of the same PD, to behavior when players are externally assigned to play a specific game. We find that cooperation rates are significantly higher in the games that were chosen.Freedom of Choice, Self-governance, Social Dilemmas, Framing

The Role of Rivalry. Public Goods versus Common-Pool Resources

Despite a large theoretical and empirical literature on public goods and common-pool resources, a systematic comparison of these two types of social dilemmas is lacking. In fact, there is considerable confusion about these two types of dilemma situations. As a result, they are often treated alike. In this paper we argue that the degree of rivalry is the fundamental difference between the two games. We show that rivalry implies that both games cannot be represented by the same game theoretic structure. Fur-thermore, we experimentally study behavior in a quadratic public good and a quadratic common-pool resource game with identical Pareto opti-mum but divergent interior Nash equilibria. The results show that partici-pants clearly perceive the differences in rivalry. Aggregate behavior in both games starts relatively close to Pareto efficiency and converges to the respective Nash equilibrium.

Die europäische Geldpolitik in der Potentialfalle?

Die Geldpolitik der Bundesbank basiert seit 1974 auf dem Konzept der potentialorientierten Geldmengensteuerung. Dr. Gerhard Maier-Rigaud vertritt die These, daß die potentialorientierte Geldpolitik ihre eigene Bezugsbasis systematisch verkleinert1. Er sieht im Übergang der geldpolitischen Kompetenz auf die Europäische Zentralbank für lange Zeit die letzte Chance für einen geldpolitischen Strategiewechsel. --

Ostracism and the Provision of a Public Good, Experimental Evidence

We analyze the effects of ostracism on cooperation in a linear public good experiment. Our results show that introducing ostracism increases contributions. Despite reductions in group size due to ostracism, the net effect on earnings is positive and significant.Experiment, Public Good, Ostracism

Cooperation in Symmetric and Asymmetric Prisoner's Dilemma Games

We experimentally study the effect of asymmetry on cooperation in a 40 period prisoner's dilemma game in fixed partner design. We distinguish between a high and low payoff symmetric prisoner's dilemma and an asymmetric game combined out of both symmetric ones. Asymmetry significantly decreases cooperation, as low-type players are more likely to defect after mutual cooperation while high-type players initiate cooperation more often than the former. Asymmetry also has a significant negative effect on the stability of cooperation rendering long sequences of mutual cooperation extremely rare.Symmetry, Asymmetry, Prisoner's Dilemma, Experiments

Four Contributions to Experimental Economics

In the following four chapters, distinct but related experimental research analyzing strategic and non-strategic economic behavior is presented. Chapter 2, entitled "Cooperation in Symmetric and Asymmetric Prisoner's Dilemma Games" is a systematic study of behavior in symmetric and asymmetric prisoner's dilemma games. The prisoner's dilemma is one of the key models in many disciplines for now over five decades. Previous prisoner's dilemma experiments show that in contrast to theoretical predictions, cooperation rates are generally very high in the symmetric payoff variant of the game. Chapter 2 studies cooperation in the prisoner's dilemma in a more realistic scenario by systematically analyzing the effects of asymmetric payoffs. Already in the early nineties Murnighan et al. (1990) noted that "research has been inexplicably absent on the effects of asymmetry". The present study takes this concern into account and focuses on this much broader type of conflict expanding the limited and rather unsystematic research conducted in this area. It analyzes and discusses the effect of asymmetry on cooperation in a 40 period prisoner's dilemma game in fixed partner design. A distinction is made between a high and low payoff symmetric prisoner's dilemma on the one hand and an asymmetric game combined out of both symmetric ones on the other hand. Asymmetry significantly decreases cooperation, as low-type players are more likely to defect after mutual cooperation while high-type players initiate cooperation more often than the former. Asymmetry also has a significant negative effect on the stability of cooperation rendering long sequences of mutual cooperation extremely rare. These results are not only a valuable addition to the existing (mostly symmetric) prisoner's dilemma literature but are also of relevance for understanding reciprocity, equity and fairness especially in light of recent theoretical developments based exclusively on symmetric experimental games. Chapter 3, entitled "Assignment versus Choice in Prisoner's Dilemma Experiments'' compares behavior in a repeated prisoner's dilemma game when players can choose between two different representations of the same prisoner's dilemma, to behavior when players are assigned to play a specific game. The chapter is concerned with the methodological question of the external validity of experimental research based on the assignment of participants to experimental games or decision situations. Experimental findings may systematically misrepresent field outcomes if assigning participants to experiments has an impact on the decisions made by the participants in the experiment and if such an assignment does not occur in the field. The chapter therefore analyzes to what extent experimental deviations from actual situations due to the assignment of participants is based exclusively on the possibility of self-selection or sorting, or whether choice has an important behavioral effect in itself. The chapter extends the results obtained in the experimental psychology literature by analyzing whether choice effects are also found in strategic contexts, rendering them of particular interest to economic environments. Based on the idea that choice either via active modification of the strategic environment or by passive self-selection into a particular strategic environment may be an important property of many empirical problems studied using experimental methods, the research goal is to separate a choice effect from sorting or self-selection effects. The experimental results clearly indicate that the mere fact that participants can choose the game they want to play has a statistically significant impact on behavior. Cooperation rates are up to 60% higher in the games that were not assigned to but chosen by participants. These findings are consistent with the robust evidence of the psychology literature on non-strategic contexts that choice increases motivation, trust, and performance. Given that in many contexts agents choose the strategic situation they get involved in, assigning participants to experiments may affect the external validity of some experimental findings. Chapter 4, entitled "The Role of Rivalry - Public Goods versus Common-Pool Resources" moves from the 2 person prisoner's dilemma game structure to the analysis of behavior in a 4 person quadratic public good and a quadratic common-pool resource game. Despite a large theoretical and empirical literature on public goods and common-pool resources, a systematic comparison of these two types of social dilemmas is lacking. In fact, there is some confusion about these two types of dilemma situations. As a result, they are often treated alike. An explicit example of this is provided by Gintis (2000) who argues that while "common pool resource and public goods games are equivalent for Homo Oeconomicus, people treat them quite differently in practice. This is because the status quo in the public goods game is the individual keeping all the money in the private account, while the status quo in the common pool resource game is that the resource is not being used at all." In line with the theoretical literature, the chapter first establishes theoretically that public good and common-pool resource games as used in the experimental literature are two distinct types of social dilemmas, the fundamental difference between the two games being the degree of rivalry. It is shown that the distinguishing feature of these two types of games lies in the distributional factor that determines whether the good is rival or non-rival. This difference gives rise to two distinct strategic environments. Based on these theoretical differences an experiment is devised that tests whether the theoretical differences have an impact on behavior. The results show that participants clearly respond to the differences in rivalry. Aggregate behavior in both games starts relatively close to Pareto efficiency and converges quickly to the respective Nash equilibrium. This clearly indicates that the differences in rivalry affect behavior, strengthening the importance of differentiating between the two types of games. Despite this difference reflecting the structure of the two games, there appear to be some behavioral similarities. In both games, aggregate behavior starts in the neighborhood of the Pareto optimum and moves rather quickly to the respective aggregate Nash equilibrium. Chapter 5 entitled "Purchase Decisions with Non-linear Pricing Options under Risk" moves away from a strategic game setting to an analysis of decisions under risk. The chapter reports on an experimental investigation of purchase decisions with linear and non-linear pricing under risk. Standard economic theory suggests that customers should be indifferent to the format of a price reduction. In particular this implies that one would expect a customer to switch from one pricing scheme to another (one supplier to another) as long as there is at least an expected reduction in the effective purchase price. The recent surge in the use of rebates, discounts, bonus and point schemes implemented by retailers but also observed in other levels of the production chain begs the question of whether traditional economic explanations do fully account for the increased usage of non-linear pricing methods. An understanding of potential behavioral reasons for using such pricing schemes - as presented in this chapter - may not only be relevant for their design, but also for wider policy considerations. The experiment presented is based on a single period stochastic inventory problem with endogenous cost. It extends classic binary lottery experiments to test standard decision theoretic predictions concerning purchasing behavior in a rebate and a discount scheme. The question to what extent customers continue to purchase under two mathematically isomorph formats of non-linear schemes even if switching to a linear pricing scheme is optimal is investigated. The results indicate that rebate and discount schemes exert a statistically significant attraction on customers. Given the increased role of non-linear pricing schemes, systematic deviations from optimal behavior are an important element in the design of such schemes and may raise consumer protection and competition policy issues. The chapter concludes with a discussion on how the results can be explained by decision heuristics.</p

Part 2: Consumer Data: Introduction

The obvious issue of consumer data in the context of consumer policy is the mass of data that consumers voluntarily or involuntarily produce and diffuse. Thereby, consumers run the risk that their data is not only being used to their benefit, but also being abused. This is particularly the case with personal and sensitive data that can clearly lead to serious harm for consumers, if this data falls into the wrong hands. Typically, in an open market economy there are commercial interests, seeking new, technical ways to access consumer data for the sake of profit maximisation. The contributions to this part show that this is an important field to be addressed by consumer policy

Nudging towards a healthier life? Conceptualising the role of health apps and wearables between empowerment and manipulation

"What once has been thought, cannot be taken back." (Friedrich Dürrenmatt, The Physicists) In Dürrenmatts play, the physicist Möbius has discovered the world formula and is afraid of its destructive potential, which poses a threat to global security. In order to ensure that his dismal discovery will not become harmful, he checks into a lunatic asylum. Tragically, his plan fails and his discovery falls into the wrong hands, which leads him to resignation and to the above-quoted insight. The lesson to be drawn from this play is that technological innovations have a huge influence on individual and social behaviour and that we cannot stop new technology from being used. However, we have the possibility to establish forms of public governance, ensuring that innovation works for the individual and common good. Health apps and wearables may appear to be a comparatively minor innovation, but they have the potential to change our society significantly, and the widespread use of this technology reminds us that it is high-time to analyse its potential, ranging from empowerment to the manipulation of users
