个体经济发展规模萎缩的政府管理环境分析

2000年以来,个体经济发展规模出现萎缩,其面临的管理环境欠佳是重要原因。主要表现为对个体户收费过多、缺乏管理和监督、设定门槛过高、扶持力度不够以及个协的运作方式与市场经济的要求不吻合等。为了加快个体经济的发展,增加就业,稳定社会秩序,必须改进政府管理方式,优化政府管理环境。

Beyond cheap talk: management's informative tone in corporate disclosures

This study investigates the information content of Management Discussion and Analysis (MD&A) reports of listed Chinese companies. We develop a Chinese word dictionary and measure the tones of MD&As. Our results indicate that tone is positively associated with future earnings and is particularly useful when a firm's future prospect is uncertain, accounting information is difficult to understand, or board monitoring is strong. Further analyses show that tone also predicts future cash flow, future sales growth, market reactions, analysts’ revisions, and institutional investors’ shareholdings. Together, we provide robust evidence that in emerging markets such as China, management tone conveys valuable information beyond cheap talk.     

互联网与业务流程融合的创新扩散及关键因素研究

依据创新扩散理论与流程观，提出一种企业互联网融合（互联网与业务流程融合）测度模型，包括信息化管理影响因素和相关假设，并将互联网与价值链上业务流程融合规模作为互联网融合的度量标准。基于196家传统企业调查数据，采用Logistic模型和结构方程建模对样本数据进行对比分析，验证所提出的模型及假设，揭示企业实施互联网技术支持业务活动的状况，鉴别企业之间互联网融合差异的关键解释因素，同时提出一种研究企业实施互联网技术支持业务活动的新途径。

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.
