We show that US consumer inflation expectations are formed using a variant of adaptive expectations proposed by Mankiw et al. (2004). In particular, expectations behave differently when food and energy prices rise sharply relative to other prices. Using the recently proposed test of Homm and Breitung (2012), we analyze the 1982–2010 period and identify seven periods where the headline price ind...

At the production of superconductors the compaction of powderform raw materials can be made by means of HERF (H~gh Energy Rate Forming) "powder in tube" techniques, too. The compacting processes of the powders in the metal tubes fitted with metal cores were tested by the authors in the cases of explosive and electromagnetic formings. In order to compare the compacted material structures in the ...
