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:
The GEJ seeks to publish original and innovative research, as well as novel analysis, relating to the global economy. While its main emphasis is economic, the GEJ is a multi-disciplinary journal. The GEJ''s contents mirror the diverse interests and approaches of scholars involved with the international dimensions of business, economics, finance, history, law, marketing, management, political science, and related areas. The GEJ also welcomes scholarly contributions from officials with government agencies, international agencies, and non-governmental organizations. One over-arching theme that unites IT&FA members and gives focus to this journal is the complex globalization process, involving flows of goods and services, money, people, and information.
