Are Fluctuations Inherited?

(How) Are features Inherited?

Two experiments provide evidence that our conceptual systems represent hierarchical relations between concepts in more than one way. Specifically, hierarchical relations may be represented via criteria inclusion or kind specification. The experiments provide the first evidence that these two ways of representing hierarchical relations mediate feature inheritance in systematically different ways...

Darwin’s view has had particular importance because of the central role mutation plays in his theory of biological evolution. Mutation provides the variation (raw material) upon which natural selection acts. Implicit in this view is a very important assumption. In Darwin’s model, sel...

Are Output Fluctuations Transitory?

According to the conventional view of the business cycle, fluctuations in output represent temporary deviations from trend. The purpose of this paper is to question this conventional view. If fluctuations in output are dominated by temporary deviations from the natural rate of output, then an unexpected change in output today should not substantially change one's forecast of output in, say, fiv...
