Dispersion in Analysts’ Earnings Forecasts and Market Efficiency

Recent studies show that firms with higher analysts’ earnings forecasts dispersion subsequently have lower returns than firms with lower forecasts dispersion. This paper evaluates alternative explanations for the dispersion–return relation using a stochastic dominance approach. We aim to discriminate between the hypothesis that some asset pricing models can explain the puzzling negative relation between dispersion and stock returns, and the alternative hypothesis that the dispersion effect is mainly driven by investor irrationality and thus is an evidence of a failure of efficient markets. We find that low dispersion stocks dominate high dispersion stocks by second‐ and third‐order stochastic dominance over the period from 1976 to 2012. Our results imply that any investor who is risk‐averse and prefers positive skewness would unambiguously prefer low dispersion stocks to high dispersion stocks. We conclude that the dispersion effect is more likely evidence of market inefficiency, rather than a result of omitted risk factors.     

Optimal education policies under endogenous borrowing constraints

This paper studies optimal education policies under endogenous borrowing constraints in a standard life-cycle model. In a closed economy, a policy that appropriately bundles an education subsidy with an old-age pension can restore the complete market allocation. Such a policy also removes persistent indeterminacies and endogenous fluctuations that exist in its absence. In a small open economy, a similar policy may restore the complete market allocation for a wide range of parameters, a range much wider than previously believed. These results broaden the rationale for a two-armed welfare state (education and pension) to a large class of economies.     

Environmentally sustainable or economically sustainable? The effect of Chinese manufacturing firms' corporate sustainable strategy on their green performances

Environmentally and economically sustainable strategies are predicted to influence the public perception of a firm's green performance in terms of environmental protection as well as corporate social responsibility as a whole. We empirically tested this prediction with the data from 214 Chinese manufacturing firms. Our empirical findings showed that firms' environmentally sustainable strategies are more important compared with the economic ones in shaping firms' green performances. Moreover, we also found a significant moderating effect of employees' education on the relationship between the two sustainable strategies and firms' green performances. We explain the findings and conclude with a discussion of the implications of our findings for academic researchers and practitioners.     

The Effect of SNAP and School Food Programs on Food Security,Diet Quality,and Food Spending: Sensitivity to Program Reporting Error

There is an extensive research literature on the effects of the Supplemental Nutrition Assistance Program (SNAP) on food‐related outcomes which has shown somewhat mixed results but generally favorable effects. However, most of the research has used data sets whose information on SNAP participation is gathered from responses on household surveys, and such responses are subject to reporting error. This study uses the National Household Food Acquisition and Purchase Survey data set to examine the effect of reporting error on food‐related outcomes, for that data set contains information on SNAP participation gathered from government administrative records. Our analysis shows that the degree of reporting error is small and has little effect on the estimated impact of participation in the SNAP program on food security, diet quality, and food spending. A supplemental analysis of the effect of school food programs likewise shows no difference in using survey or administrative data in the analysis.
