To See Is To Believe: Common Expectations In Experimental Asset Markets

We experimentally manipulate agents' information regarding the rationality of others in a setting in which previous studies have found irrationality to be present, namely the asset market experiments introduced by Smith, Suchanek, and Williams (Econometrica, 1988). Recent studies suggest that mispricing in such markets may be an artefact of confusion, which can be reduced by training subjects to understand the diminishing fundamental value. We reconsider this view, and argue that when it is made public knowledge that training has occurred, this may also reduce uncertainty over the behavior of others and facilitate the formation of common expectations. Our design disentangles the direct effect of training from the indirect e_ect of its public knowledge, and our results indicate a distinct effect of public knowledge over and above that of training alon

Gestational Age and Birth Weight in Relation to School Performance of 10-Year-Old Children: A Follow-up Study of Children Born after 32 Completed Weeks

ABSTRACT BACKGROUND. Children born extremely premature (Ͻ28 weeks) or with a very low birth weight (Ͻ1500 g) have a poorer school performance than children born at term with a normal birth weight. Much less is known about children of higher gestational ages and birth weights. We studied gestational age after 32 completed weeks and birth weight in relation to the child's school performance at the age of 10 years
