The extracellular patch-clamp technique was used to examine how halothane, a general anesthetic, affects the properties of single nicotinic acetylcholine receptor channels of embryonic Xenopus skeletal muscle cells grown in culture. Under control conditions, single-channel events showed a bimodal distribution on the basis of current amplitudes. This distribution was maintained during exposure t...

Did the Internet make international markets more integrated? To address this question, we study long-term price differences and their speed of convergence, based on a unique data base for identical goods sold in both online traditional “brick-and-mortar” distribution channels, covering ten European countries. We find that are closely comparable between channels. Furthermore, converge only sligh...

This study elucidates the effectiveness of intermediary channels in driving sales at social commerce sites (SCSs).

But as Paul Samuelson (1955, 1969) has demonstrated, in general equlib...
