27. Interim efficiency with MEU-preferences
Recently Kajii and (2008) proposed to characterize interim efficient allocations in an exchange economy under asymmetric information when uncertainty is represented by multiple posteriors. When agents have Bewley's incomplete preferences, Kajii and Ui (2008) proposed a necessary and sufficient condition on the set of posteriors. However, when agents have Gil

28. Testing the Optimality of Aggregate Consumption Decisions: Is there Rule-of-Thumb Behavior?
Consumption is an important macroeconomic aggregate, being about 70% of GNP. Finding sub-optimal behavior in consumption decisions casts a serious doubt on whether optimizing behavior is applicable on an economy-wide scale, which, in turn, challenge whether it is applicable at all. This paper has several contributions to the literature on consumption optimal

29. Involvement of GABAergic mechanisms of the dorsal periaqueductal gray and inferior colliculus on unconditioned fear
The fact that the dorsal periaqueductal gray (dPAG) and inferior colliculus (IC), together with superior colliculus, medial hypothalamus and amygdala, constitute the brain aversion system has been well-established. Stepwise increases in the intensity of electrical stimulation of dPAG or IC cause freezing and escape responses, which are followed by a freezing

30. L-histidine reduces inhibitory avoidance in Carassius auratus submitted to cerebellar ablation
The effect of post-training treatment with L-histidine (LH) on the memory consolidation of inhibitory avoidance was investigated in Carassius auratus submitted to cerebellar ablation. The inhibitory avoidance procedure included 3 days: one habituation day, one training day (5 trials, T1-T5) and one test day. On the training day, each fish was placed individu

31. O modelo principal-agente com risco moral sob a Ãtica da economia comportamental
The principal-multiagent model with moral hazard and loss averse agents is considered here.

32. A relação entre a teoria física e o desejo na filosofia política de Hobbes / The relationship between physical theory and the desire by the political philosophy of Hobbes
This dissertation tries to show the relationship between the physical and the political theories of Thomas Hobbes. This is possible because Hobbes made no distinction between the way in which physical bodies and humans move: every body moves as a result of the action of another body. When a body is affected by another, movements or conatus appear within itse
