NEWS AND INFORMATION RIGIDITY: FURTHER EVIDENCE FROM GDP GROWTH FORECASTS
The study investigates the existence and the extent of information rigidity in gross domestic product (GDP) growth forecasts among 25 developed and 18 developing economies during 2002–2017 period utilizing a survey dataset never explored before on this issue. In general, the study finds ample evidence of information rigidity. However, it is not as common and as severe as it is in earlier studies. Our study also finds ample evidence of overreaction to new information. Information rigidity is present during the recession period for the developed countries, and we find some evidence of information gathering picking up during the recession period. Overall, we notice less forecast rigidity or inefficiency in our study compared to some earlier studies. Our multi-country test results show that forecast revisions depend on both own country and cross-country lagged revisions. In general, forecast revisions of developed economies, especially USA, prompt revisions in other developed and developing economies. Similarly, some developing countries’ forecast revisions prompt revisions in other developed and developing countries although at smaller magnitudes. Therefore, we confirm from earlier studies that one source of forecast rigidity is not to incorporate overseas events in forecast revisions quickly and completely.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
