Using a large international data set we analyze whether business cycle forecasters tend to herd or anti-herd. Applying different measures of economic crises, we distinguish between normal economic circumstances and times of crises. We fnd evidence for anti-herding behavior for most industrial economies, i.e. forecasters eliberately stick out their neck with extreme forecasts for strategic reasons. For a set of emerging market economies, by contrast, we find evidence for herding behavior. We relate this finding to the high incidence of economic and financial crises in these countries. A test for herding behavior during economic crises confirms that forecasters tend to herd in times of high forecast uncertainty.
We used the oil-price forecasts of the 'Survey of Professional Forecasters' published by the European Central Bank to analyze whether oil-price forecasters herd or anti-herd. Oil-price forecasts are consistent with herding (anti-herding) of forecasters if forecasts are biased towards (away from) the consensus forecast. Based on a new empirical test developed by Bernhardt et al. (J. Financ. Econ. 80: 657-675, 2006), we found strong evidence of anti-herding among oil-price forecasters.
On the international consistency of short-term, medium-term, and long-term oil price forecasts
(2011)
We derive internal consistency restrictions on short-term, mediumterm, and long-term oil price forecasts. We then analyze whether oil price forecasts extracted from the Survey of Professional Forecasters conducted by the European Central Bank satisfy these internal consistency restrictions. We find that neither short-term forecasts are consistent with medium-term forecasts nor that medium-term forecasts are consistent with long-term forecasts. Using a more complex expectation formation structure featuring a distributed lag structure, however, we find stronger evidence of internal consistency of mediumterm forecasts with long-term forecasts.
Do FOMC members herd?
(2011)
Twice a year FOMC members submit forecasts for growth, unemployment and inflation to be published in the Humphrey-Hawkins Report to Congress. In this paper we use individual FOMC forecasts to assess whether these forecasts exhibit herding behavior, a pattern often found in private sector forecasts. While growth and unemployment forecast do not show herding behavior, the inflation forecasts show strong evidence of anti-herding, i.e. FOMC members intentionally scatter their forecasts around the consensus. Interestingly, anti-herding is more important for nonvoting members than for voters.
We use the ECB's Survey of Professional Forecaster to show that euro area expectations are consistent with standard macroeconomic building blocks such as the Phillips curve, Okun's law, and the Taylor rule. Moreover, the paper finds that the financial and economic crisis of 2007-2009 did not change the expectation formation process as professional forecasters still adopt macroeconomic building blocks for their forecast. The scepticism that has recently been raised concerning macroeconomic building blocks has apparently not yet affected professional forecasts. On the contrary, we conclude that professional forecasters still have faith in macroeconomic building blocks.
