Housing Starts in Canada, Japan, and the United States: Do Forecasters Herd?

Recent price trends in housing markets may reflect herding of market participants. A natural question is whether such herding, to the extent that it occurred, reflects herding in forecasts of professional forecasters. Using survey data for Canada, Japan, and the United States, we did not find evidence of forecaster herding. On the contrary, forecasters anti-herd and, thereby, tend to intentionally scatter their forecasts around the consensus forecast. The extent of anti-herding seems to vary over time. For Canada and the United States, we found that more pronounced anti-herding leads to lower forecast accuracy.     

Disagreement and Biases in Inflation Expectations

Disagreement in inflation expectations observed from survey data varies systematically over time in a way that reflects the level and variance of current inflation. This paper offers a simple explanation for these facts based on asymmetries in the forecasters' costs of over- and underpredicting inflation. Our model implies (i) biased forecasts, (ii) positive serial correlation in forecast errors, (iii) a cross-sectional dispersion that rises with the level and the variance of the inflation rate, and (iv) predictability of forecast errors at different horizons by means of the spread between the short- and long-term variance of inflation. We find empirically that these patterns are present in inflation forecasts from the Survey of Professional Forecasters. A constant bias component, not explained by asymmetric loss and rational expectations, is required to explain the shift in the sign of the bias observed for a substantial portion of forecasters around 1982.     

Lockup and Voluntary Earnings Forecast Disclosure in IPOs

We examine the relation between lockup length and voluntary earnings forecast disclosures for IPOs in Singapore. Unlike firms in the United States, companies in Singapore are allowed to provide earnings forecasts in their IPO prospectuses. We find that forecasters are more likely to accept longer lockup periods, so that the lockup expires after the first post-IPO earnings announcement. Our study also shows that because the lockup agreement removes personal incentives to issue aggressive forecasts, IPO firms tend to issue conservative forecasts. Overall, our results suggest that the lockup mechanism adds credibility to the earnings forecast given in the IPO prospectus.     

Analysts’ accrual-related over-optimism: do analyst characteristics play a role?

Bradshaw et al. (J Acc Res 39:45–74, 2001) find that analyst forecast over-optimism is greater for firms with high accruals. This “accrual-related over-optimism” is generally interpreted as evidence that analyst forecasts do not fully incorporate predictable earnings reversals associated with high accruals. We investigate whether analyst experience, access to resources (brokerage size), and portfolio complexity moderate the relation between over-optimistic forecasts and high accruals. We demonstrate the robustness of accrual-related over-optimism to controls for cash flow and prior forecast errors. We find that accrual-related over-optimism is lower for analysts with greater general experience and for analysts following fewer firms but find only limited evidence of lower accrual-related over-optimism for analysts from larger brokerages and for analysts following fewer industries.     

Survey forecasts in Brazil: A prismatic assessment of epidemiology,performance, and determinants

This paper assesses the behavior of survey forecasts in Brazil during the inflation targeting regime, when managing expectations is one of the cornerstones of the conduct of monetary policy. The distinctive database of the survey conducted by the Central Bank of Brazil (BCB) among professional forecasters allows for a thorough investigation of the epidemiology, determinants, and performance of forecasts. The main results are: i) top performing forecasters are influential to other forecasters; ii) survey forecasts perform better than vector autoregressive model-based forecasts; iii) common forecast errors prevail over idiosyncratic components across respondents; iv) inflation targets play an important role in inflation expectations; and v) agents perceive the BCB as following a Taylor rule consistent with inflation targeting. The last two suggest high credibility of the monetary authority.     

The strategy of professional forecasting

We develop and compare two theories of professional forecasters’ strategic behavior. The first theory, reputational cheap talk, posits that forecasters endeavor to convince the market that they are well informed. The market evaluates their forecasting talent on the basis of the forecasts and the realized state. If the market expects forecasters to report their posterior expectations honestly, then forecasts are shaded toward the prior mean. With correct market expectations, equilibrium forecasts are imprecise but not shaded. The second theory posits that forecasters compete in a forecasting contest with pre-specified rules. In a winner-take-all contest, equilibrium forecasts are excessively differentiated.     

Do German security analysts herd?

We employ an innovative methodology suggested by Bernhardt et al. (J. Financ. Econ. 80:657–675, 2006) to examine the herding (or anti-herding) behavior of German analysts regarding earnings forecasts. This methodology avoids well-known shortcomings often encountered in related studies, such as correlated information signals, unexpected common shocks to earnings, systematic optimism or pessimism, or forecast target mismeasurement. Our findings suggest that German analysts anti-herd, that is, they systematically issue earnings forecasts that are further away from the consensus forecast than their private information indicates. Furthermore, we analyze the association between herding behavior and different characteristics, including the size of the brokerage, general or firm-specific experience, and the coverage of firms on the Neuer Markt. We mainly confirm findings for the United States, for example, that anti-herding is more severe in cases of higher competition among analysts. Contrary to anecdotal evidence, we also find anti-herding behavior in earnings forecasts for Neuer Markt firms during the “new economy” bubble.

The informativeness of analyst forecast revisions and the valuation of R&D-intensive firms

Prior studies (e.g., [McNichols and O’Brien, 1997] and [Diether et al., 2002]) find that analysts are less willing to disclose unfavorable earnings forecasts than to disclose favorable forecasts, and this tendency induces an optimistic bias in disclosed forecasts that increases with the degree of earnings uncertainty. Building on these findings, we predict that, in the context of R&D-intensive industries, there should be differential informativeness and asymmetric valuation roles for upward versus downward analyst forecast revisions. Consistent with our predictions, we find the following evidence: (i) analyst forecast revisions contain a downward bias, causing upward revisions to under-represent, whereas downward revisions to over-represent, changes in true earnings expectations, with the extent of over/under-representation greater for firms with higher R&D expenditures; (ii) upward revisions are associated with more rapid reductions in earnings uncertainties (proxied by forecast dispersions) than downward revisions, mainly for high R&D firms; and (iii) upward revisions are more effective in mitigating the return differentials between high and low R&D firms (as documented in Chan et al., 2001).     

Voluntary Disclosure of Management Earnings Forecasts in IPO Prospectuses

Asymmetric information and mechanisms for its resolution in the initial public offering (IPO) process are subjects of extensive research and debate. In this paper, we investigate the impact of one such mechanism, namely voluntary disclosure of management earnings forecasts by issuers of IPOs, as a means of reducing asymmetric information as well as ex ante uncertainty. Our focus is on the relative importance of this voluntary disclosure mechanism on both IPO underpricing and post‐issue return performance. Our results indicate that management earnings forecasts provide important and incremental information compared to other means of reducing asymmetric information, and these disclosures appear to improve the environment of IPO issuance. For example, our underpricing results show that firms that choose to provide forecasts leave 'less money on the table' with a lower degree of underpricing. In terms of post‐issue performance, firms whose forecasts turn out to be optimistic are penalized significantly relative to other forecasters and non‐forecasters.     

Asset management in the German insurance industry: the quality of interest rate forecasts

Chopra and Ziemba (J.?Portf. Manag. 19: 6?C11, 1993) show that for asset only allocations the return forecasts are more important than assumptions about the variance-covariance matrix of the returns. Following Basse et al. (ZVersWiss 96: 617?C648, 2007) the same holds true for the asset liability management (ALM) of insurance companies. Given the high quotas of bonds in the real as well as optimized insurance portfolios, interest rate forecasts are of exceptional importance. Therefore this paper examines some of these estimates for the European market using techniques of time series analysis. A?set of criteria for the evaluation of the forecasts is presented. While some results seem to be quite favorable for forecasters, others indicate that none of the analyzed forecasts seems to provide relevant information about the future development. There is lot of evidence showing that interest rates are very difficult to predict. Some hints clearly point towards herd behavior among forecasters.     

Loss aversion and financial reporting: A possible explanation for the prevalence of discontinuities in reported earnings

We formalize the notion, first suggested by Burgstahler and Dichev (1997), that earnings discontinuities can be caused by reference dependence. We extend the signaling model by Guttman et al. (2006) to include loss-averse investors. The presence of loss aversion causes the separating equilibrium (without discontinuities in the distribution of reported earnings) to disappear, while the partially-pooling equilibrium (exhibiting discontinuities) may prevail. This implies that the presence of loss-averse investors will cause earnings discontinuities around reference points. The prime candidates for investors’ reference points are earnings benchmarks such as zero earnings, last year’s earnings and analyst forecasts. Our model provides an explanation for why earnings discontinuities appear around earnings benchmarks.     

Forecasting metal prices: Do forecasters herd?

We analyze more than 20,000 forecasts of nine metal prices at four different forecast horizons. We document that forecasts are heterogeneous and report that anti-herding appears to be a source of this heterogeneity. Forecaster anti-herding reflects strategic interactions among forecasters that foster incentives to scatter forecasts around a consensus forecast.     

Volatility Forecasting in the Hang Seng Index using the GARCH Approach

The aim of this paper is to add to the literature on volatility forecasting using data from the Hong Kong stock market to determine if forecasts from GARCH based models can outperform simple historical averaging models. Overall, unlike previous studies we find that the GARCH models with non-Normal distributions show a robust volatility forecasting performance in comparison to the historical models. The results indicate that although not all models outperform simple historical averaging, the EGARCH based models, with non-normal conditional volatility, tend to produce more accurate out-of-sample forecasts using both standard measures of forecast accuracy and financial loss functions. In addition we test for asymmetric adjustment in the Hang Seng, finding strong evidence of asymmetries due to the domination of financial and property firms in this market.     

Macro information environment change and the quality of management earnings forecasts

The 1990s were characterized by substantial increases in the performance of and investor reliance on financial analysts. Because managers possess superior private information and issue forecasts to align investors’ expectations with their own, we predict that managers increased the quality of their earnings forecasts during the 1990s in order to keep pace with the improved forward-looking information provided by financial analysts, upon which investors increasingly relied. Using a sample of 2,437 management earnings forecasts, we document an increase in management earnings forecast precision, management earnings forecast accuracy, and managers’ tendency to explain earnings forecasts in 1993–1996 relative to 1983–1986. Given that these forecast characteristics are linked to greater informativeness and credibility, we also document that the information content of management earnings forecasts, as measured by the strength of share price responses to forecast news, increased in 1993–1996 relative to 1983–1986. As expected, the increased information content of management forecasts primarily occurred for firms covered by financial analysts.

Discussion of “Are earnings forecasts more accurate when accompanied by cash flow forecasts?”

Call et al. (Rev Account Stud 2009, this issue) demonstrate that, relative to analysts who issue earnings but not cash flow forecasts, analysts who issue both forecasts (i) produce relatively more accurate earnings forecasts, (ii) have a better understanding of the persistence of current earnings, and (iii) are less likely to get fired. In my discussion, I highlight some general challenges facing research on analyst cash flow forecasts, demonstrate the diminishing difference in the relative accuracy over time (including its compete elimination by 2004), and examine the sensitivity of some of the evidence in Call et al. (2009) to the age of the forecast and to the presence of extreme bad-news earnings surprises.     

Optimal investments for risk- and ambiguity-averse preferences: a duality approach

Ambiguity, also called Knightian or model uncertainty, is a key feature in financial modeling. A recent paper by Maccheroni et al. (preprint, 2004) characterizes investor preferences under aversion against both risk and ambiguity. Their result shows that these preferences can be numerically represented in terms of convex risk measures. In this paper we study the corresponding problem of optimal investment over a given time horizon, using a duality approach and building upon the results by Kramkov and Schachermayer (Ann. Appl. Probab. 9, 904–950, 1999; Ann. Appl. Probab. 13, 1504–1516, 2003). Supported by Deutsche Forschungsgemeinschaft through the SFB 649 “Economic Risk”.     

On the rationality and efficiency of inflation forecasts: Evidence from advanced and emerging market economies

This paper provides a full characterization of inflation rate forecasts using the mean values from Consensus Economics for a sample of 78 advanced and emerging economies between 1989 and 2014. It also assesses the performance of inflation rate forecasts around business cycles’ turning points. As expected, that inflation forecasts start to mirror the actual data as the forecast horizon draws to a close, particularly in advanced economies. The mean forecast error is positive and larger than one point when we pool all countries, but this masks inter-group differences. Moreover, we find evidence for biasedness, inefficiency or information rigidities, with a clear tendency for “forecast smoothing”. Accounting for cross-country informational linkages is important: forecasters fail to adjust their inflation forecasts quick enough in response to domestic news and news from abroad. Finally, during recession episodes forecasts generally appear to be inefficient. The same holds true for recoveries.     

Financial forecasts in the presence of asymmetric loss aversion, skewness and excess kurtosis

We present closed-form results for the out-of-sample forecasts under the joint presence of asymmetric loss and non-normality, extending the results of Granger [1969. Operations Research Quarterly 20, 199–207; 1999. Spanish Economic Review 1, 161–173] and Christoffersen and Diebold [1997. Econometric Theory 13, 808–817]. We consider the LinEx and Double LinEx loss functions and non-normal distributions in the form of the Gram–Charlier class. We show how the preference asymmetries interact with the distribution asymmetries to determine optimal forecasts which contain the optimal predictors under symmetry and normality as special cases. We also examine the implications of our results for the development of forecast rationality tests, extending the work of Batchelor and Peel [1998. Economics Letters 61, 49–54]. Our results are relevant for the design of efficient investment and risk management policies.     

Are Some Forecasters Really Better than Others? A Note*

In this paper, we use bootstrap approach to test the null hypothesis that all forecasters in the U.S. Surveys of Professional Forecasters (SPF) have equal ability. Our bootstrap procedure captures any potential cross-sectional and serial correlation in the forecast errors while preserving the unbalanced nature of the panel data. Once we account for the presence of cross-sectional and serial correlation in the forecast errors while resampling, we find convincing evidence that some individuals really are better than others—this is in sharp contrast to the findings of D'Agostino et al. (2012).     

Optimal Timing of Real Estate Investment under an Asymmetric Duopoly

This paper examines the sub-game equilibrium strategies for a duopoly real option model consisting of two firms with asymmetric demand functions. The relative strength of the firms is found to have significant impact on the firms’ equilibrium strategies. Preemptive strategies are critical if difference in strength between the two competing firms is relatively small. Short bursts and recession induced overbuilding are two outcomes in the asymmetric duopoly model. The model, however, predicts that the two phenomena occur in earlier phases of market cycles, rather than in the state of depression. In a depressed market with high volatility, the leader and the follower will both choose the waiting strategies. Construction cascade is, therefore, not an expected phenomenon in a depressed market in the asymmetric duopoly framework. Please forward your comments to the second author at rststf@nus.edu.sg.
