tion of Contract Enforcement and Price Rigidity», Economic Journal, 119(536), 333-353.

         We study the impact of reputational incentives in markets characterised by moral hazard prob-
         lems. Social preferences have been shown to enhance contract enforcement in these markets,
         while at the same time generating considerable wage and price rigidity. Reputation powerfully
         amplifies the positive effects of social preferences on contract enforcement by increasing con-
         tract efficiency substantially. This effect is, however, associated with a considerable bilateralisa-
         tion of market interactions, suggesting that it may aggravate price rigidities. Surprisingly, reputa-
         tion in fact weakens the wage and price rigidities arising from social preferences. Thus, in mar-
         kets characterised by moral hazard, reputational incentives unambiguously increase mutually
         beneficial exchanges, reduce rents, and render markets more responsive to supply and demand
         shocks.

Fehr, Ernst (2009). «On the Economics and Biology of Trust», Journal of the European Eco-

http://dx.doi.org/10.1162/JEEA.2009.7.2-3.235
         In recent years, many social scientists have claimed that trust plays an important role in eco-
         nomic and social transactions. Despite its proposed importance, the measurement and the defi-
         nition of trust seem to be not fully settled, and the identification of the exact role of trust in eco-
         nomic interactions has proven to be elusive. It is still not clear whether trust is just an epiphe-
         nomenon of good institutions or whether it plays an independent causal role capable of shaping
         important aggregate economic outcomes. In this paper, I rely on a behavioral definition of trust
         that enables us to relate it to economic primitives such as preferences and beliefs. I review
         strong biological and behavioral evidence indicating that trusting is not just a special case of risk-
         taking, but based on important forms of social preferences such as betrayal aversion. Behavior-
         ally defined trust also opens the door for understanding national and ethnic trust differences in
         terms of differences in preferences and beliefs, and it suggests ways to examine and interpret a
         causal role of trust.

http://dx.doi.org/10.1162/JEEA.2009.7.2-3.561
         In this paper we study the role of incomplete ex ante contracts for ex post trade. Previous ex-
         perimental evidence indicates that a contract provides a reference point for entitlements when
         the terms are negotiated in a competitive market. We show that this finding no longer holds when
         the terms are determined in a non-competitive way. Our results imply that the presence of a
         “fundamental transformation” (i.e., the transition from a competitive market to a bilateral relation-
         ship) is important for a contract to become a reference point. To the best of our knowledge this
         behavioral aspect of the fundamental transformation has not been shown before.

         Scholars today are under increasing pressure to publish in A journals, the main role of which
         consists in certifying that a paper meets traditional academic standards. Consequences of this
         pressure are multiple authorship, the slicing of ideas, and incentives to deviate from the truth.
         The overburdened reviewers' evaluations are characterized by selfish efforts to protect their intel-
         lectual capital and to avoid risk. The behaviour of editors depends much on whether there are a
         large or small number of editors.
         The editors of Kyklos respond to these developments by welcoming innovative papers that go
         beyond standardized orthodoxy.

         Relative Einkommensunterschiede lösen innerhalb einer Referenzgruppe oftmals Neid aus und
         beeinflussen damit die individuelle Leistungsbereitschaft. In der ökonomischen Forschung ist bis-
         lang dieser Zusammenhang wenig untersucht worden. Unser Beitrag analysiert den Einfluss von
         relativen Einkommensunterschieden auf die Leistung von Fußballprofis der deutschen Bundesli-
         ga. Insgesamt werden 1040 Spieler über einen Zeitraum von 8 Spielzeiten zwischen 1995 und
         2004 untersucht. Relative Einkommensunterschiede zwischen Mannschaftskollegen erweisen
         sich als entscheidender Einfluss auf die individuelle Leistung der Spieler. Eine Verschlechterung
         in der relativen Einkommensposition vermindert ceteris paribus die individuelle Leistungsbereit-
         schaft. Eine höhere Einkommensungleichheit verstärkt solche positionsbedingten Externalitäten.

http://dx.doi.org/10.2202/1935-1682.1929
         The paper investigates the relationship between pro-social norms and its implications for im-
         proved environmental outcomes. This is an area, which has been neglected in the environmental
         economics literature. We provide empirical evidence to demonstrate a small but significant posi-
         tive impact between perceived environmental cooperation (reduced public littering) and in-
         creased voluntary environmental morale. For this purpose we use European Values Survey
         (EVS) data for 30 European countries. We also demonstrate that Western European countries
         are more sensitive to perceived environmental cooperation than the public in Eastern Europe. In-
         terestingly, the results also demonstrate that environmental morale is strongly correlated with
         several socio-economic and environmental variables. Several robustness tests are conducted to
         check the validity of the results.

         Confronted with a rich sensory environment, the brain must learn statistical regularities across

         visual target-detection task while being exposed to distractor stimuli. Unknown to them, auditory
         distractors predicted the presence or absence of subsequent visual distractors. We modeled in-
         cidental learning of these associations using a Rescorla-Wagner (RW) model. Activity in primary
         visual cortex and putamen reflected learning-dependent surprise: these areas responded pro-
         gressively more to unpredicted, and progressively less to predicted visual stimuli. Critically, this
         prediction-error response was observed even when the absence of a visual stimulus was surpris-
         ing. We investigated the underlying mechanism by embedding the RW model into a DCM to
         show that auditory to visual connectivity changed significantly over time as a function of predic-
         tion error. Thus, consistent with predictive coding models of perception, associative learning is
         mediated by prediction-error dependent changes in connectivity. These results posit a dual role
         for prediction-error in encoding surprise and driving associative plasticity.

         The phenomenon of empathy entails the ability to share the affective experiences of others. In
         recent years social neuroscience made considerable progress in revealing the mechanisms that
         enable a person to feel what another is feeling. The present review provides an in-depth and
         critical discussion of these findings. Consistent evidence shows that sharing the emotions of oth-
         ers is associated with activation in neural structures that are also active during the first-hand ex-
         perience of that emotion. Part of the neural activation shared between self- and other-related ex-
         periences seems to be rather automatically activated. However, recent studies also show that
         empathy is a highly flexible phenomenon, and that vicarious responses are malleable with re-
         spect to a number of factors—such as contextual appraisal, the interpersonal relationship be-
         tween empathizer and other, or the perspective adopted during observation of the other. Future
         investigations are needed to provide more detailed insights into these factors and their neural
         underpinnings. Questions such as whether individual differences in empathy can be explained by
         stable personality traits, whether we can train ourselves to be more empathic, and how empathy
         relates to prosocial behavior are of utmost relevance for both science and society.

phrenia: From Abnormal Synaptic Plasticity to Failures of Self-monitoring», Schizophrenia
Bulletin, 35, 509-527.
http://dx.doi.org/10.1093/schbul/sbn176
         Over the last 2 decades, a large number of neurophysiological and neuroimaging studies of pa-
         tients with schizophrenia have furnished in vivo evidence for dysconnectivity, ie, abnormal func-
         tional integration of brain processes. While the evidence for dysconnectivity in schizophrenia is
         strong, its etiology, pathophysiological mechanisms, and significance for clinical symptoms are
         unclear. First, dysconnectivity could result from aberrant wiring of connections during develop-
         ment, from aberrant synaptic plasticity, or from both. Second, it is not clear how schizophrenic
         symptoms can be understood mechanistically as a consequence of dysconnectivity. Third, if
         dysconnectivity is the primary pathophysiology, and not just an epiphenomenon, then it should
         provide a mechanistic explanation for known empirical facts about schizophrenia. This article ad-
         dresses these 3 issues in the framework of the dysconnection hypothesis. This theory postulates
         that the core pathology in schizophrenia resides in aberrant N-methyl-D-aspartate receptor
         (NMDAR)-mediated synaptic plasticity due to abnormal regulation of NMDARs by neuromodula-
         tory transmitters like dopamine, serotonin, or acetylcholine. We argue that this neurobiological
         mechanism can explain failures of self-monitoring, leading to a mechanistic explanation for first-
         rank symptoms as pathognomonic features of schizophrenia, and may provide a basis for future
         diagnostic classifications with physiologically defined patient subgroups. Finally, we test the ex-
         planatory power of our theory against a list of empirical facts about schizophrenia.
