When no news is good news – The decrease in investor fear after the FOMC announcement

No News is Good News

It seems plausible that an increase in stock market volatility raises required stock returns, and thus lowers stock prices. We develop a formal model of this volatility feedback effect using a simple model of changing variance (a quadratic generalized autoregressive conditionally heteroskedastic, or QGARCH, model). Our model is asymmetric and helps to explain the negative skewness and excess ku...

NO news is good news.

NO news is good news for plants.

The organization of redox signaling and the use of nitric oxide (NO) to transmit information, modulate biological processes or create cellular damage are highly complex. Recent reports provide an exceptional picture of NO production, of the regulation of NO bioactivity through detoxification reactions and of biochemical events by which NO transduces signals into cellular responses, in particula...

News, Uncertainty and Economic Fluctuations (No News Is Good News)

We formalize the idea that uncertainty is generated by news about future developments in economic conditions which are not perfectly predictable by the agents. With a simple model of limited information we show that uncertainty shocks can be obtained as the square of news shocks. We develop a two-step econometric procedure to estimate the effects of news and we find highly nonlinear effects. La...

Labour analgesia and the baby: good news is no news.

When investigating different methods of maternal pain relief in labour, neonatal outcome has not always been at the forefront, or else maternal changes, such as haemodynamics, fever, length of labour, need for oxytocin or type of delivery, are taken as surrogates for neonatal outcome. It is essential to examine the actual baby and to appreciate that labour pain itself has adverse consequences f...
