A couple of recent papers have shifted the focus towards disagreement of professional forecasters. When dealing with survey data that is sampled at a frequency higher than annual and that includes only fixed event forecasts, e.g. expectation of average annual growth rates measures of disagreement across forecasters naturally are distorted by a component that mainly reflects the time varying forecast horizon. We use data from the Survey of Professional Forecasters, which reports both fixed event and fixed horizon forecasts, to evaluate different methods for extracting the fundamental component of disagreement. Based on the paper's results we suggest two methods to estimate dispersion measures from panels of fixed event forecasts: a moving average transformation of the underlying forecasts and estimation with constant forecast-horizon- effects. Both models are easy to handle and deliver equally well performing results, which show a surprisingly high correlation (up to 0:94) with the true dispersion.

AbstractThe main goal of this paper is to examine the conditional pricing effect of return dispersion on the cross section of returns. We observe a systematic conditional relation between dispersion and return even after controlling for market, size and book‐to‐market factors. However, we find that return dispersion risk is asymmetrically priced with a significantly positive premium observed during periods of large market gains only. The findings are found to be robust to alternative conditional specifications of market returns, suggesting asymmetric pricing effect of the return dispersion factor. We provide alternative explanations for the systematic risk captured by the return dispersion factor and discuss implications for portfolio management and corporate decisions.

This paper constructs internationally consistent measures of macroeconomic uncertainty. Our econometric framework extracts uncertainty from revisions in data obtained from standardized national accounts. Applying our model to quarterly post-WWII real-time data, we estimate macroeconomic uncertainty for 39 countries. The cross-country dimension of our uncertainty data allows us to identify the effects of uncertainty shocks on economic activity under different employment protection legislation. Our empirical findings suggest that the effects of uncertainty shocks are stronger and more persistent in countries with low employment protection compared to countries with high employment protection. These empirical findings are in line with a theoretical model under varying firing cost.

This study examines whether macroeconomic uncertainty affects the forecast accuracy of financial analysts in an international setting. We use inflation and foreign exchange volatility as measures of macroeconomic uncertainty. We find strong evidence that forecast accuracy decreases in the level of macroeconomic uncertainty. Further, we document that the negative association between forecast accuracy and macroeconomic variables is more pronounced for emerging economies than developed economies. Overall our results suggest that macroeconomic uncertainty represents a unique dimension in the complexities associated with predicting future firm performance.

Mobile phones have been central to ICT innovation since the introduction of the smartphone and constant-quality prices are a barometer of their economic impact. Official consumer price indices (CPIs) indicate that impact differs wildly across countries: for the 2008–18 period, average annual rates of mobile phone inflation range from no change to a 25 per cent decline among 12 key countries examined in this paper. Although evidence indicates certain fundamental factors are at play, mis-measurement may lead the spread in rates to be overstated. Examination of methods employed in CPI calculation, including quality adjustment and index formulas, illuminates but does not resolve the mystery.
