Outline of Final Research Achievements

In this research, as a proposal to supplement management forecasts, we try to combine forecasts using analyst forecasts. We use the Bayesian approach using past forecasts proposed by Winkler (1981) to synthesize management and analyst forecasts. In order to estimate the variance-covariance matrix, we used the forecast data for TSE 1st section listed companies from 2009 to 2016, and we estimated the combined forecast for 2017. As a result of the analysis, the prediction error of the combined forecast is lower than the forecast of management and analysts in both earnings per share and ordinary income.
For the ordinary profit, we obtained statistically significantly lower prediction error and the possibility that the combined forecast is useful.
