What Is the Headline Effect?

The headline effect refers to the disproportionate impact that negative news headlines in the popular press can have on economic behavior and market prices. Many economists believe negative headlines make consumers more reluctant to spend money.

The effect can be magnified by media sensationalism or risk aversion, as seen in coverage of gas prices or the Greek debt crisis, with consequences for both corporations and economies.

Headline Effect's Impact

How the Headline Effect Amplifies Market Reactions

Whether it is justified or not, the investing public's reaction to a headline can be very dramatic and out of proportion when compared with the reaction to good news in the headlines. Therefore, when a government agency or central bank releases an unfavorable economic report, traders, investors, and members of the investing public might disproportionately react to that bad news by converting, selling, or shorting funds away from any stocks, currencies, or other investments that have been affected. While this market reaction is, to some extent, natural and expected, the headline effect can speed up and worsen the severity of the market reaction by bringing bad news to the forefront of the trading public's mind.

Causes Behind the Headline Effect

Economists and market observers have put forth several possible explanations for the headline effect. Most likely, a combination of different factors are in play, but here are a few possibilities. First, media sensationalism may be responsible for the headline effect. The media know that bad news sells and that attention-grabbing headlines generate more clicks and page views, so negative news tends to be featured and promoted more heavily. People will naturally pay more attention and react more strongly to stories that are run for widely, frequently, or prominently by news outlets.

Second, risk aversion and loss aversion may also be responsible for the headline effect. Most people tend to weight potential dangers, risks, and losses more heavily in their decision-making. This can easily mean that people will be more likely to act on negative news than positive news.

Finally, institutional factors that bias the behavior of businesses and fiduciaries toward caution may also be responsible for the headline effect. These include things like the basic accounting principle of conservatism or the prudential rules that certain institutional funds such as pensions are required to follow.

Examples Illustrating the Headline Effect

An example of a headline effect is the media's extensive coverage of the impact of rising gas prices on consumers. Some economists believe that the more attention that is paid to small increases in the price of gasoline, the more likely it is that consumers will be more cautious about spending their discretionary dollars. The headline effect can be regarded as the difference between decreases in discretionary spending that are rationally justifiable based on economic fundamentals and those that occur purely as a result of news coverage.

Another example of the headline effect is the effect of the Greek debt crisis on the value of the euro. The economic crisis in Greece was credited with weakening the euro significantly, despite the fact that the Greek economy accounted for only 2% of the eurozone’s overall economic productivity.1 The public’s reaction to bad news about the Greek economy affected not only the eurozone but also countries outside the eurozone, such as the United Kingdom, that rely heavily on trade with the eurozone to support their own economies. Some have said that the headline effect could be as drastic as undermining the future of the euro and the European Union itself.
