"Biased Forecasts to Affect Voting Decisions? The Brexit Case" [job market paper]

Abstract

This paper introduces macroeconomic forecasters as political agents and suggests that they use their forecasts to influence voting outcomes. We develop a probabilistic voting model in which voters do not have complete information about the future states of the economy and have to rely on macroeconomic forecasters. The model predicts that it is optimal for forecasters with economic interest (stakes) and influence to publish biased forecasts prior to a referendum. We test our theory using high-frequency data at the forecaster level surrounding the Brexit referendum. The results show that forecasters with stakes and influence released much more pessimistic estimates for GDP growth in the following year than other forecasters. Actual GDP growth rate in 2017 shows that forecasters with stakes and influence were also more incorrect than other institutions and the propaganda bias explains up to 50 percent of their forecast error.

"Inefficient Use of Competitors’ Forecasts?"

Abstract

This paper assesses to what extent forecasters make efficient use of competitors’ forecasts. Using a panel of forecasters, I find that forecasters underuse information from their competitors in their forecasts for current and next year’s annual GDP growth and inflation. The results also show that forecasters increase the attention to their competitors as the forecast horizon decreases. In a model of noisy information with fixed target forecasts, I confirm the empirical results of underuse of competitors’ information. I also extend the model to include a revision cost and show how this can explain the observed inefficiency and observed horizon dynamics. Using the same model framework, I also rule out overconfidence as the main explanation of the observed behavior.
