Shocks to equity options' ATM implied volatility (ATMIV) are followed by persistently lower short-term rates. Shocks to the ratio of OTM puts' over OTM calls' implied volatilities (P/C) are followed by persistently higher rates. The stock's and Treasury-bond's ATMIV indices, which measure market...

This paper examines the relationship between technological change and wages using pooled cross-sectional industry-level data and several alternative indicators of the rate of introduction of new technology.
